The Future of Envelope Technology: How Digitalization is Changing Mail
In a world driven by technology, the way we communicate has undergone a significant transformation. Traditional mail, once the primary means of sending messages and documents, has now evolved to keep pace with the digital era. Envelope technology, the cornerstone of the mailing process, is experiencing a fundamental shift due to digitalization. Let's explore how this technological revolution is reshaping the future of mail.
Enhanced Security and Efficiency
Digitalization has introduced advanced security measures to envelope technology. Encryption techniques, electronic signatures, and secure file transfers have made sending important documents more reliable and confidential. The days of worrying about lost or tampered mail are gradually becoming a thing of the past.
Moreover, digital envelope technology offers enhanced efficiency. Automated processes can sort and categorize mail quickly, reducing human error and minimizing delivery delays. The integration of artificial intelligence and machine learning algorithms ensures precise identification and routing of mail, making the entire process more streamlined.
Paperless Communication and Sustainability
A significant consequence of digitalization in envelope technology is the rise of paperless communication. Emails, online messaging platforms, and electronic document management systems have become the go-to methods for exchanging information. The environmental benefits of reducing paper waste are substantial, leading to increased sustainability.
With digital alternatives to traditional mail, businesses and individuals now have the convenience of instant communication, eliminating the need for physical delivery. Digital envelopes allow for the transmission of documents, contracts, and other essential files at the click of a button, making remote work and collaborations more efficient.

The digital revolution is here, and it's changing the way we send and receive mail.


Ninth International Workshop on Statistical Relational AI
The purpose of the Statistical Relational AI (StarAI) workshop is to bring together researchers and practitioners from three fields: logical (or relational) AI/learning, probabilistic (or statistical) AI/learning and neural approaches for AI/learning with knowledge graphs and other structured data. These fields share many key features and often solve similar problems and tasks. Until recently, however, research in them has progressed independently with little or no interaction. The fields often use different terminology for the same concepts and, as a result, keeping-up and understanding the results in the other field is cumbersome, thus slowing down research. Our long term goal is to change this by achieving a synergy between logical, statistical and neural AI. As a stepping stone towards realizing this big picture view on AI, we are organizing the Ninth International Workshop on Statistical Relational AI at the 34th AAAI Conference on Artificial Intelligence (AAAI) in New York, on February 7th 2020.
StarAI will be a one day workshop with short paper presentations, a poster session, and three invited speakers.
Authors should submit either a full paper reporting on novel technical contributions or work in progress (AAAI style, up to 7 pages excluding references), a short position paper (AAAI style, up to 2 pages excluding references), or an already published work (verbatim, no page limit, citing original work) in PDF format via EasyChair. All submitted papers will be carefully peer-reviewed by multiple reviewers and low-quality or off-topic papers will be rejected. Accepted papers will be presented as a short talk and poster.
StarAI is currently provoking a lot of new research and has tremendous theoretical and practical implications. Theoretically, combining logic and probability in a unified representation and building general-purpose reasoning tools for it has been the dream of AI, dating back to the late 1980s. Practically, successful StarAI tools will enable new applications in several large, complex real-world domains including those involving big data, social networks, natural language processing, bioinformatics, the web, robotics and computer vision. Such domains are often characterized by rich relational structure and large amounts of uncertainty. Logic helps to effectively handle the former while probability helps her effectively manage the latter. We seek to invite researchers in all subfields of AI to attend the workshop and to explore together how to reach the goals imagined by the early AI pioneers.
The focus of the workshop will be on general-purpose representation, reasoning and learning tools for StarAI as well as practical applications. Specifically, the workshop will encourage active participation from researchers in the following communities: satisfiability (SAT), knowledge representation (KR), constraint satisfaction and programming (CP), (inductive) logic programming (LP and ILP), graphical models and probabilistic reasoning (UAI), statistical learning (NeurIPS, ICML, and AISTATS), graph mining (KDD and ECML PKDD) and probabilistic databases (VLDB and SIGMOD). It will also actively involve researchers from more applied communities, such as natural language processing (ACL and EMNLP), information retrieval (SIGIR, WWW and WSDM), vision (CVPR and ICCV), semantic web (ISWC and ESWC) and robotics (RSS and ICRA).
Previous StarAI workshops were held in conjunction with AAAI 2010, UAI 2012, AAAI 2013, AAAI 2014, UAI 2015, IJCAI 2016, UAI 2017 and IJCAI 2018 and were among the most popular workshops at the conferences.

- Connecting the Nova
- Connecting to a computer / phone / tablet / other
- Loading some software and mapping the midi channel
- Special guitar functions
- Playing wirelessly
Connecting the Nova
Use the included extra long USB-C cable to connect the Nova to your computer / tablet / phone.
- Never use the angled connector without feeding the cable through the strap.
- If you use the straight connector when sitting, make sure to keep the connector end from bumping the seat.
USB connectors are more fragile than guitar jacks. Being rough with the cable connection can permanently damage the Nova's USB plug.
Connecting to your Computer / Phone / Tablet
Your included USB cable has USB C connectors on both ends and an adapter to USB A in case your computer doesn't have a USB C connector available.
Connecting to Something Else
You can connect to a synth or anything else that takes a midi connector. You can use a midi cable with a DIN connector plugged into the Nova, and then into your synth. In this case you will still need to have the USB cable connected to a charger or battery pack to provide power.
Now turn it on!
When you first turn on your Nova, it should show up on your device as a midi controller. The Nova is a class compliant midi device, which is a fancy way of saying it should just work.
The Nova is a midi controller which means it doesn't make any sounds of it's own. It relies on software (or hardware) that understands midi and translates the keys you press on the Nova into sounds playing from your device.
Typically we can use music software. We just tell it to use the Nova, plug in some speakers, and we are good to go!
Types of Music Software
Music software can be a lot of things. It can be:
- A stand alone player - Takes midi and just plays sounds.
- A DAW (Digital Audio Workstation) - Lets you compose songs, and use a lot of different sounds at the same time. These typically have their own instruments.
- A VST (Windows) or AU (Mac) - A plug in into a DAW, to let you choose from thousands of free and paid types of samplers / synths and classic synth emulations.
Quick Tip: If you are just starting out you may want a stand alone player (Like the free Surge XT ).
In a lot of our videos you can see we are using Ableton Live (A DAW) using a plugin called SynthMaster. For some examples of setting up with various computers / soft synths, you can check out the Knowledge Base.
- Using the Nova with an iPad - Quick and easy!
- SynthMaster (Mac, Windows) - Lots of sounds that work well with the Nova's touchpad.
- Surge XT - Great, free, stand-alone synth with some custom sounds we've designed for the Nova.
- Options for DAW's - A list of applications you might want to check out for composing music.
In your software you will most likely need to map the MIDI device to look for the Mosi Nova. Go to your Midi Settings and select the Midi device listed. You should see:
- USB Midi Device (On Mac)
- USB A (On Windows)
Note: This varies across operating systems and versions.
The Nova will play on Midi Channel 1 when it is turned on.
Load up the Surge XT, and set it up! Instructions Here
You should be able to play now! Try pressing a button on the fretboard, and tapping on the touchpad at the same time.
You can keep a finger down on the pad, and every button on the fretboard will play as you press it. Try moving your finger to morph the sound.
You can also go into Finger Tapping mode by pressing two buttons on the same string six or more frets apart. This mode means you do not need to touch the pad to trigger notes. To exit this mode, just touch the pad.
The pad itself triggers CC values which can be mapped to different sound modifiers in your software. It generates MOD (CC1) for the Y axis and CC20 for the X axis.
To map CC 1, touch next to vertical Y edge.
To map CC 20, touch next to a horizontal X edge.
If you want to try playing without being tethered by a cord, check out this article on playing wireless: Wireless Setup

An ATS or Automatic Transfer Switch is a device that is used to reroute the power in certain circumstances. For instance, the PUP or public utility power may go out at establishments during natural disasters, and ATS devices start backup generators. There are tons of issues involved in this kind of shift – not the least of these issues are making decisions about when it is safe to switch back the power.
Automatic Transfer Switches are used to make sure that there is a continuity of power supply, although it can mean various things in various situations. In a standard house, institution, or small business, the continuous power supply may mean that short power interruption can be tolerated.
For instance, if the backup generator is used to help supply backup when the public power fails, there will be a short pause while the personal generator starts up. In health institutions like hospitals, any short interruption may be a matter of life and death.
To find out more about electric current, click here for details.
There are some ways that ATS can make sure that these interruptions are as short as possible – including batteries to fill from the cessation of the PUP to the start of BGS or backup generator supply. Some of these devices sense temporary spikes and dips in PUP that precedes failure, as well as start-up generators before the complete failure of PUP.
Expert professionals like engineers usually install these devices to switch loads between two different electrical current sources. Some of these things are manual and can be activated when users flip switches, while others, such as ATS, will switch depending on how the source changes. When sources fail, the ATS may go into full effect to help energize a building.
Types of Automated Transfer Switches
In addition to soft-loaded designs, their static transfer switch and close or open transition designs are for various purposes of ATS. Open-transfer (OP) devices, as well as break-before-make devices, operate by stopping contact with one electrical source and creating contact with other sources.
It will prevent unwanted back feeding, using electricity from more than one source that competing against each other, as well as preventing the flow of electricity in unwanted directions. By contrast, closed-transfer (CT) devices or also known as make-before-break switches, will transfer electrical current without causing any forms of interruption.
How semiconductors work? Visit https://electronics.howstuffworks.com/diode.htm to find out more.
It is pretty useful for electrical equipment or structures that rely on their power in ways that even interruptions for a couple of seconds can be a matter of life and death. Unlike their OPS (open-transfer switches) counterpart, close-transfer devices find ways to load electric current to ensure that the generator can supply electricity before breaking connections from one source to another.
These devices are pretty complicated compared to their open counterparts, and users need to monitor the current flow during the transition and divert energy – using bypass capacitors – to help prevent backflows. Professionals refer to various energy sources as synchronized when the voltage difference is less than 5% or have differences in frequency of less than 0.2 Hertz.
Isochronous governors will control the shift in the current. Closed switches make sure that the transfer of electrical current can happen under these circumstances – sometimes within 100 milliseconds. These devices will turn into OTs if the CT is not possible. Lastly, Static Transfer Switches (STS) use semiconductors such as Silicon-controlled rectifiers to help shift electrical sources.
These setups use electron motion energy in semiconductors to allow the shift to happen almost immediately. They are pretty reliable, as well as perform independently of sources available, but they need to be tested to help protect loads from various interruptions in the current frequency.
How does ATS work with more than one generator?
Automated Transfer Switch setups can use more than one generator to help protect electrical operations that happen simultaneously in places that are far from each other. These systems use more than one ASCO automatic transfer switches setups to act as if there were one ATS with a single generator. This setup will let these systems act with more than one generator for purposes of, for instance, different kinds of architectural designs and structures.
Each device needs controllers to ensure that the electricity transfers effectively, efficiently, and safely between utility sources and generators. These things should be tested in directions, as well as distributing electricity accordingly. People need to make sure that they take into consideration even the smallest time differences between different generators and powering different structures. For some operations, even a short time without electricity can harm the purpose of various building designs.

This draft is about the Kernel Graphics Interface developed by the KGI Project. It is intended to give a short overview of the concepts behind, being kind of a white paper. It'll take about 20min to read, if you like to know more about it or comment on it, feel free to email the maintainer of this document. You can download a snapshot of the current sample implementation from ftp://kgi.sourceforge.net/pub/kgi. A sample implementation for Linux is currently under development, the first part - a reimplementation of the Linux console system to meet the requirements of the KGI architecture - being finished already. This includes an implementation of most of the concepts explained here. Any file references given here refer to files included in the snapshot. An online version of the source tree is available at http://kgi.sourceforge.net/source/kgi-0.9
The development of a Kernel Graphics Interface (KGI) is part of the GGI Projects effort to create a portable, fast and secure General Graphics Interface (GGI). While GGI itself is more a suite of application programming interfaces, most applications will not directly interface to KGI. Instead, KGI is intended to provide the neccessary kernel support (protection, virtualization and abstraction) in order to allow applications to benefit from graphics hardware with as little overhead as possible. Additionally, a certain amount of kernel level support for display hardware can ease the effort to meet the security and stability
requirements of modern multi-user multi-tasking operating systems.
As mentioned, KGI deals primarily with display hardware. This section should give some fundamental properties of graphics hardware and their implication on KGI design. Some of these properties make it special compared to other computer subsystems, while others are just implied by the fact that it is hardware. Most of the KGI design goals and constraints can be summarized as:Display Hardware is essential for human-machine interaction.This very obvious property makes display hardware different from all other computer componentes and implies the following design requirements for KGI:
These requirements are accompanied by the fact that display hardware is not standardized and probably the fastest evolving computer subsystem. KGI should therefore be open for future developments and not be specific to a particular graphics application programming interface. And last but not least, KGI is intended for UNIX-like operating systems, which feature multi-user multi-tasking environments. Thus KGI should allow for simple setup of independent multihead machines, featuring several workplaces per machine.
- Display ...
Display hardware must become available very early during the boot process in order to display diagnostic messages. KGI must therefore provide means to output diagnostic messages from the kernel and do this as early as possible.
- ... hardware ...
The primary intention of advanced display hardware (other than simple frame buffers) is to offload computing or memory bandwith intensive operations to specialized (co-)processing hardware, thereby freeing the main CPU for other tasks. In some aspects, display hardware therefore acts as a co-processor that needs to be virtualized - just like the main (co-)processing unit(s) (e.g. FPU, ...). On the other hand, display hardware is also a system resource that needs to be protected from accidental or intentional misuse. Finally, KGI drivers - or firmware - are (as far as common features are concerned) considered part of the display hardware and must be designed to be independent of the OS and host architecture.
- ... is essential for ...
Display hardware must be reliable. This implies that the user or operator should be able to get access to a 'rescue shell' even if graphical user interfaces are not accessible. (E.g. the graphical user interface sever crashed.) Therefore KGI must not rely on applications to free resources properly.
- ... human-machine...
Display hardware is built for humans working with computers. This requires KGI neither to prescribe nor to prevent policies if/how to share display hardware, what to do in case of non-fatal errors etc.
- ... interaction.
Display hardware must be responsive. This implies that even for highly loaded machines delays between user input and visible feedback due to this change must be short. With 3D graphics becoming more and more standard, this requires advanced hardware programming techniques, such as graphics processor virtualization, priority scheduling, "processes models" for graphics processors etc. KGI must therefore provide means to handle several processes sharing resources where this makes sense.
The KGI architecture can be structured into the following 'subsystems':
Additionally the current KGI sample implementation for Linux has also a console subsystem and compatibility module, adopted to the changes neccessary to implement the KGI architecture.
- a human-machine interaction model
- an abstract display hardware model
- physical I/O and environment operating system support
- display hardware drivers and management
- input hardware drivers and management
- application interface (graphics process management)
The subsequent text will focus on the interaction and hardware models,OS environment, display driver and application interface. The input hardware driver, console and compatibility module will not be described in much detail.
KGI is developed for multi-user multi-tasking operating systems that allow several users to run processes simultaneously, providing means to isolate (protect) processes from each other, but also to share limited resources. KGI is consequently designed to allow several users to work interactively with the same machine. It allows each user to use an arbitrary number of display and input hardware (often referred to as independent multi-head). Input and output devices are grouped to "workplaces" owned by a particular user (the one using it). In order to access resources of a particular workplace, processes must belong to the user or have explicitly been granted access to these resources.A side note:Additionally, KGI allows for virtual (textual and graphical) consoles that are mapped on physical display and input hardware (thereby becoming visible/active).
Actually all human-machine interaction hardware like sound, workplace local peripherals, etc. needs to be treated this way. However, KGI is currently limited to input and visual output. Actually, Kernel User Interface describes better what most of the KGI sample implementation for Linux does, but originally KGI was intended to handle display hardware only. Also, it should be pointed out clearly, that this Kernel User Interface is restricted to hardware drivers, protection and virtualization. Especially it must not be misunderstood as running a Graphical User Interface at kernel level, which is a common misunderstanding about KGI.
Analysing the flow of information gives a very natural model of human-machine interaction. Information going into the machine is "digitized" by input hardware. This digitizing is dealt with by the Kernel Input Interface file:kgi-0.9/kgi/include/kii/kii.h Information going out of the machine is converted by output (display) hardware. This is dealt with by the Kernel Graphics Interface file:kgi-0.9/kgi/include/kgi/kgi.h The actual information processing is done in processes that interface to hardware through abstract hardware representations, referred to as devices. Devices virtualize limited hardware resources.
All input device drivers (event sources - kii_input_t) register with a central mangagement code ( file:kgi-0.9/kgi/src/Linux/kgi.c) that enumerates input devices and groups these into so-called focuses kii_focus_t. All input devices associated with a focus send events to the same focused object (e.g. a virtual console) represented by a device (event-sink) kii_device_t. The focused object then processes the event, the result being commands sent to the display hardware represented by a device kgi_device_t. These get handed to the display hardware driver kgi_display_t, which in turn sends commands to the hardware, usually resulting in some feedback to the user.
For both KGI and KII care has been taken to separate hardware device driver specific issues (kii_input_t, kgi_display_t) from logical device representation (kii_device_t, kgi_device_t).
Despite all differences between the various graphics hardware, ranging from simple text frame buffers (Monochrome Display Adapter, LCD panels for embedded systems, etc.) up to virtual reality hardware as SGI's "Infinite Reality(TM)", certain properties of graphics hardware can be modeled and abstracted. KGI's display hardware model is intended to give a functional representation of the underlying hardware, hiding implementation details from applications.
Display hardware controls some attributes of the visible display area either independently for small sub-areas (e.g. the color of a pixel) or the whole display area (e.g. brightness). KGI categorizes attributes into attributes that can be controlled independently per pixel, left and probably right frame (e.g. color, alpha value) and attributes that can be controlled independently per pixel, but common to all frames (e.g. z-value, stencil masks, ...) Sometimes the number for bits stored per attribute needs to be given, which is done using a bitmask indicating which attributes are present and a zero-terminated array of 8bit unsigned integers. (file:kgi-0.9/kgi/include/kgi/kgi.h gives details about the attributes defined.)
Images are a rectangular set of pixels, the attributes of those being stored as an array of unsigned integers (the frame buffer). Not all of the bits stored per pixel may control visible attributes (e.g. z-values). Certain attributes (usually color or color index value) are read from the buffer in a certain order, control the properties of a given visible image unit (dot) and serialized into a dot stream. There might be some scaling and interpolation units or look up tables before the final dot stream assembly, which is why KGI distinguishes between image units (pixel) and dot stream units (dots).
- Dot Stream Converters and Dot Ports
The dot streams generated by several image units (e.g. a GUI frame buffer and a video overlay buffer) are passed to some conversion device or processing unit before being converted into a sensable physical property. These devices are referred to as "dot stream converters" (e.g. a overlay processor, video DAC, etc.). KGI represents these devices by a dot port, which is a description of the transfer protocol or dot stream format. A dot stream converter is simply a number of input dot ports an one output dot port. Several dot stream converters may be connected, building a tree with dot stream converters as nodes and images as leaves. The root node is a dot port that represents the monitor.
- Display Modes
Modern display hardware can be operated in a great variety of modes, e.g. color indexed mode, text mode, true color mode, true color with video overlay etc. Instead of enumerating and standardizing these modes (like1024x768 pixel with 8bit Red, 8bit Green, 8bit Blue and 8bit Alpha), KGI provides means to check if a certain requested mode is possible or not. Roughly speaking, a mode describes the hardware operation mode (number of images, attributes per image, dot stream converter properties, etc.).
- Display Resources
As a result of a successful mode-check, the hardware driver(s) will return a set of resources available in this mode. While images, dot streams and dot stream converters describe the transformation process from the internal buffer representation to a visible image, display resources provide means to alter image buffers and internal buffers (like texture memory). Currently KGI specifies memory mapped I/O regions and accelerators. It is planned to extend these to support the VESA Media Interface (VMI), card-local I2O buses, proprietary buses (S3 Streams Interface), etc.
Some resources are static, e.g. video input and output buffers, and may influence the number of possible modes. Other resources are mode-dependent, e.g. may only be availiable in certain modes or operating system environments. For each resource access policy restrictions are given, describing the hardware driver's constraints about sharing this resource (exclusive maps, write/read re-ordering, allowed access widths, etc.). Some display resources (e.g. frame buffers) may be exported directly to applications, allowing for fast access and high performance. Other resources (e.g. accelerators) are not directly exported, but require some buffering and context management mechanism. This is described in more detail in the Application Interface section below.
KGI display drivers bridge between the display hardware and the application interface. For the most common hardware design, a modular driver architecture has been developed to allow for maximum re-usage of coding efforts. The most common design of display hardware can be sketched like this:
Though recent developments allow the integration of some parts into one piece of silicon, the functional units can still be identified. Each functional unit (except memory) is represented by a driver module, using a well defined internal interface. A fully operational display hardware driver is obtained by linking the proper (binary) subsystem drivers together. For example, a graphics card based on a 3Dlabs PermediaNT, with a TI TVP 3026 ramdac with integrated clock chip and a multisync monitor may reuse the ramdac, clock and monitor driver written for a S3 Vision968 based board with TI TVP 3026 and multisync monitor. A proof-of-concept implementation for this concept has been released by the GGI Project in early 1998. Valuable feedback and conclusions have been drawn from this implementation, resulting in an improved version of the internal module interface. A sample driver for the architecture described in this document is being developed, but only semi-operational yet. However, it is developed far enough to give a impression how to use the internal module interface. As KGI display drivers may run in kernel mode, the use of floating point operations is not allowed. All drivers must conform to certain requirements, such as they must not call other than the KGI environment functions. Also, KGI drivers must not rely on certain advanced features such as interrupt handling, DMA support etc. being available. However, if present they may benefit from this. This allows KGI driver to be used as userspace drivers or in-kernel drivers without modification.
The intra-display driver interface is defined in kgi-0.9/drv/display/kgi/module.h
A main goal for the display driver modules was to be independent of the underlying Operating System Environment. This requires the usual abstraction of system-dependent data types, physical I/O methods, IRQ/DMA handling and environment. The system dependent data types and the environment functions (memset, etc.) are considered straightforward and will not be discussed in detail here.
- I/O regions
Physical I/O is abstracted by so-called regions, which are a physical contigous part of an address space. For each address space, the following abstractions/operations apply:
Subregions may be exported to application or other drivers, e.g. a driver may claim a region of 64MB, containing 32MB frame buffer and 32MB control registers and export only 32MB to the application using
- for each address space virtual, physical, I/O and bus addresses are defined. Virtual addresses are used by the driver access this region. Physical addresses are used to establish mappings of this region into other virtual address spaces. I/O addresses are the addresses that the device will respond to if applied at the address select lines. Bus addresses are used to access the device from other devices on the same bus. (E.g. a frame grabber writing directly to the frame buffer.)
- before accessing a region, the I/O address of a device must be specified and the region must either be allocated (allowing auto-configuration) or claimed. If this is successful, the driver is granted exclusive use of this region. Upon driver termination or if not neccessary for operating the hardware, the allocated regions must be freed again.
- The driver may only access the region using the virtual address obtained during registration and special I/O functions. Currently defined are simple input and output (read/write) operations, as well as copy and string input/output operations. Some operations may not be defined, depending on the capabilities of the I/O bus system.
a memory mapped I/O resource. For details of the definitions, see file:kgi-0.9/kgi/include/kgi/io.h
KGI contains some input drivers modified to be aware of the multihead issues. This is for historical reasons as at the time of project start no unified input drivers were around.
Applications do not interface to graphics hardware directly, unless approved by the display driver. Instead, an abstract representation of graphics hardware is defined and accessed by applications using a special device file and standard UNIX file operations (open, close, ioctl, mmap, read).
|are used to maintain virtualization of display hardware resources|
|ioctl||is used to control overall behaviour of display hardware and to send commands to the hardware (e.g. setting of look-up tables, control of video overlay scaling, etc.).|
|read||is used to report asynchronous events (accelerator programming error, accelerator finished, request for shared mapping from other processes etc.)|
|mmap||is used to gain direct access to accelerator command buffers, memory mapped I/O regions, such as video stream ports, accelerator register files, frame buffer regions etc. Applications that want to use direct access may be required to conform to certain restrictions, e.g. access only with certain widths, etc. This may be indicated by setting access permissions for the special file and using set-user-id features, or implementing some verification protocol with the session manager. KGI tries not to impose policy here, except that the driver's constraints have to be met.|
This article was intended to give an overview about the KGI architecture to handle display hardware. Currently the KGI Project is working on a improved proof-of-concept implementation (kgi-0.9) using Linux as a target OS, that will implement the enhanced concepts presented in this articles, such as graphics processor virtualization as part of a first version of a direct-rendering architecture. This will include an experimental X server (XKGI) adopted to this architecture.
The implementation of the KGI human-machine interface model is already finished and currently it beta-testing state. It already allows to setup true multi-head machines with XFree-4.0. However, most advanced features require native KGI drivers, which are still under development.

Today, technology is prominent in many HVAC trends mainly because it’s easily accessible and a lot smarter. AI, IoT, and virtual reality technologies are changing the HVAC industry in every possible way and have solved multiple problems.
Some studies depict that the HVAC market can grow exponentially from 197.0 billion USD in 2021 to 277 billion USD by 2025. So technology has become a major contributor to this industry’s growth. The best part of this growth is these advancements have moved towards sustainability and energy-saving.
In this post, we shall discuss the 10 new HVAC technology trends that benefit both the HVAC companies and their customers.
Advanced HVAC Technology Trends of 2022
Here are the 10 latest HVAC technology trends that will be trending in 2022.
1. HVAC Zoning System
HVAC zoning system or Zoned HVAC refers to the heating and cooling system where the ductwork is damped to regulate and redirect air to specific areas of the house alone.
Here a house is divided into different areas, and each part is individually controlled by separate smart thermostats using which the user can control and monitor the temperatures. Since each room has temperature settings, the best temperature for each area is achieved, and there is a decrease in usage in empty rooms.
So by creating customized temperature zones throughout the house, you can increase comfort and save energy bills.
The zones system can be applied to the VRF, air conditioning, or ductless systems. Also, zone systems can be installed in existing systems by using a zone control panel.
Almost every household that has adopted the HVAC zoning system benefits because there is an increased probability for houses to have a room too hot or too cold. Or at least family members with different temperature preferences. The HVAC zoning system can fulfill the different comfort needs and save monthly energy bills. So HVAC Zoning System is among the best HVAC innovations.
2. Energy Analysis Software
Another exciting HVAC technology is the energy analysis software. Earlier, HVAC technicians or users had to manually check their energy bills, energy consumption, and other data when deciding to install a new HVAC unit.
But the advancements in technology have eased this process. Various energy analysis software now helps the contractors save time and effort in researching the energy history while also saving customers money.
So this analytical software helps calculate the lifetime energy usage and other data related to the HVAC system and also tracks the efficiency of an HVAC system. Thus after analyzing it calculate the savings in comparison to other systems.
This software has greatly helped customers and HVAC professionals make the best decision concerning their HVAC system and save energy costs.
Also, these software programs can quickly lead to HVAC innovation on a large scale. So today, engineers and architects can use this platform to find the appropriate equipment for their design and get an idea about the building’s lifetime energy consumption. And even if needed, consider the implementation of non-HVAC techniques like reflective roofing, geothermal, and night-sky cooling.
3. Thermally Driven Air Conditioning
Thermally driven air conditioning in HVAC systems is among the HVAC trends in 2022.
It is calculated that large, portable air conditioner units consume about 4,100 watts per hour, while mid-sized air conditioners can use 2900 watts each hour. And the electricity that powers these systems is mainly derived from fossil fuels than other energy forms.
So in an attempt to create an eco-friendly future, the advanced HVAC systems have incorporated thermally driven air conditioning that supplies electricity via solar power and thus have become sustainable systems.
And this method provides an energy-efficient cooling method that can be an alternative to the traditional air conditioners, and the biggest advantage it offers is eliminating electricity costs.
Also, these systems have proved to remove heat with evaporation at low pressure.
Though this technology has existed for many years, the ongoing research has helped curate a cost-efficient way to tackle energy consumption and carbon emissions and, thus, positively influence the environment.
4. Dual Fuel Heat Pumps
Heat pumps are generally more efficient and provide maximum comfort when using a combination of fuels. That said, the dual fuel heat pumps used in the HVAC systems come as a combination of an electric heat pump and gas furnace, providing efficient and cost-effective heating and cooling.
During hot summers, the dual fuel heat pump becomes a high-efficiency central air conditioner, whereas, in the mid-spring or fall, it works as a cost-effective and efficient heat. Meanwhile, during winter, the heat pump shuts off, and the furnace takes over when the temperatures drop to greater heights.
So the pumps automatically alternate between electric and gas pumps based on the outside temperature and provide higher energy efficiency, which is the next level of innovation.
Though the initial cost of installing a dual-fuel heat pump is higher than a conventional system, in the long run, you will save your pocket. Also, this upgrade can be covered in the energy-saving tax credit and rebates.
So if you plan to install a dual fuel pump, consult the HVAC professional about the same. Or, if you are an HVAC contractor, explain this advanced HVAC technology and its tax benefit to your customer.
5. Smart HVAC technologies
You reached the office only to realize that you had left the AC ON. So will you return home to turn it off or just take advantage of smart technology and turn it off from the office itself?
Smart HVAC technology can be at your rescue at these crucial times. Also, imagine this scenario where you can get the AC turned on 15 minutes before you reach home. Isn’t it cool?
So smart technology can offer you the convenience of setting triggers and controlling the HVAC system from your mobile device. With advanced HVAC systems equipped with wifi capabilities, you can send commands to the HVAC units using your handheld device.
Smart controllers, smart ACs, and programmable thermostats can offer numerous benefits like remote monitoring and low energy bills. Apart from comfort and convenience, you can achieve energy efficiency and savings by setting triggers to activate your HVAC unit when needed.
Thus, ensure that the HVAC unit is not running unnecessarily throughout the day.
Now that many houses are adopting this technology; you can connect your unit with other smart appliances in your house and set them to work on automated conditions based on your preferences.
6. Predictive Maintenance
The predictive maintenance technique uses condition-monitoring tools and techniques that help monitor the performance of a structure or piece of equipment during its operation.
Here predictive maintenance is one of the smart HVAC technologies that use IoT and AI to sense data on air quality and equipment status to predict the perfect time for maintenance.
Since HVAC installations, repairs and maintenance are extremely costly, nobody would want to go through unnecessary maintenance at an odd time. So it is vital to stay alert about the working of the HVAC system and predict when HVAC maintenance is required before a serious issue pop-up.
Overall, this technique helps reduce costly unexpected breakdowns in the systems and helps the HVAC professionals plan maintenance around their production schedule. Other benefits of this technique include improved air quality, better comfort, and a safer home.
7. Virtual Reality
While the installation, repair, or replacement of HVAC systems is generally done remotely, the training of HVAC technicians doesn’t necessarily be. HVAC technicians can also get trained for exceptional circumstances through virtual reality.
HVAC companies find the Virtual Reality training cost-effective because these professionals can use virtual components and quickly develop their skills before moving into the real-world work culture. So this practice saves not only money but also time.
So the training with Virtual Reality is made possible using a virtual simulator. Using this device, technicians can learn the process of installation or troubleshooting the new system. With the HVAC industry blooming, the workforce is also expected to increase. So virtual reality has made it possible for a large group of people to be trained in lesser time and, most importantly, with less equipment.
Another crucial benefit of this latest HVAC technology is that Virtual Reality training can provide safety, especially for beginners. As for the companies, this can be easy for them to handle risk and reduce the HVAC training cost.
8. Geothermal HVAC systems
With sustainable or green technology being the need of the hour, the HVAC industry has adopted different technologies that can contribute to the word eco-friendly.
One such technology is geothermal heating and cooling systems. This system is an excellent option to naturally cool a house using water, heat pumps, and an underground piping system. No refrigerant is used as geothermal heat pumps exchange heat with the ground, making them environmentally friendly.
During summer, the heat is transferred to the ground after it is absorbed from the building. Whereas during winter, the heat is absorbed from the ground, then transferred into the building. Though installing geothermal systems is expensive, they deliver higher efficiency, and it is a better option than thermally driven AC systems.
9. Ductless HVAC Systems
Ductless heating and cooling systems offer two important benefits: they are efficient, and the installation doesn’t require extensive ducts, making them easy to install at less cost.
Apart from this, a ductless system offers zoning capability where you can heat or cool a particular zone. The Ductless HVAC systems can be installed in moderate temperature zones and harsh temperature zones, and you can witness great seasonal efficiency ratings.
10. 3D Printed Air Conditioners
The 3D printing technology has gained more attention for more than a decade simply for its quick printing process of various products. 3D-printed air conditioners are a perfect example of how technology can meet HVAC unusually.
These conditioners have a 3D porous block that absorbs humidity and cools the air via evaporation. Since 3D printer products are durable and require less maintenance, this technology is expected to bloom this year despite this technology being first created in 2015.

Lithium-ion batteries are increasingly used in mobile applications where mechanical vibrations and
shocks are a constant companion. This work shows how these mechanical loads affect lithium-ion
cells. Therefore pouch and cylindrical cells are stressed with vibrational and shock profiles according to the UN 38.3 standard. Additionally, a vibration test is set up to reflect stress in real-world applications and is carried out for 186 days. The effects of the load profiles on the tested cells are investigated by capacity measurement, impedance spectroscopy, micro-X-ray computed tomography and post mortem analyses.


"Houston, it looks like we got us a Dragon by the tail"
Well that was amazing: I just watched the live video feed from NASA of the SpaceX Dragon capsule docking (well, being grabbed by a robot arm) with the International Space Station. This is a pretty important moment: it's the first time a privately funded mission has made it to space and linked up with NASA.
It was pretty impressive, to watch the robot arm being carefully guided to link up with the capture mechanism on the Dragon: that's a lot of complicated equipment being wielded in a place with very little margin for error, and watching the tense faces at Houston goes to show how hard it all is. But of course, that sort of thing has happened loads of times now, with the ISS having been in orbit for years, and numerous other complicated things (such as Hubble) being delicately positioned in orbit.
That isn't the point though: so far, every space mission has had the backing of very big, well funded (in comparison) government agencies. The achievements of NASA et al. over the past decades have obviously been immense - humans on the moon, probes to the edge of the solar system, robots on other planets. These are right and proper things for publicly funded science to be doing - but if it takes a massive government-funded organisation to get anything into space, that's going to be a problem. It's not the kind of setup that will let humans really do space, or allow the kind of unlimited exploration and adventure that we'd all love to see.
NASA's budget, as we recently became only too aware, can only stretch so far, and making the hard choices between different missions is no fun. Now though, SpaceX has conclusively shown it is possible for a private company, in just a few years, to become capable of getting hardware into space, and interacting with the bigger players already there. Hopefully they and other private companies will soon be capable of dealing with the necessary commercial aspect of space - launching satellites, tourism, and so on - leaving publicly funded bodies to get on with the fun stuff.
Of course, today's achievement didn't happen spontaneously, and it certainly wasn't cheap: it took many many years to get this done, and months of planning just for the docking; and I'm guessing the price tag (for the mission itself and years of development) and was pretty heavy. Running up and down to space on a whim is still a long way away. But the fact that a private company can get to space is the important point, and illustrates how far we have come in the last fifty years. It's often lamented that humans have not been back to the moon since the '70s - almost as if we lost interest - but in those days, it took a large part of the wealth of a world superpower to do it. This is clearly no longer the case - and it can only get easier from here. The true age of space flight could soon begin.

Light giving off diodes (LEDs) are an electronic light source. LEDs started life as light indications in electrical components made by Hewlett Packard. The light is an outcome of electrons releasing energy in the form of photons much better called electroluminescence.
Their energy effectiveness, low maintenance, toughness and also lengthy life imply that they are now a bright choice to the energy-hungry and also delicate analogue lights most of us grew up with.
Initially their expense limited their use as a day-to-day light source. Nonetheless ever-increasing energy prices combined with improved manufacturing procedure has actually made them a sensible alternative to Mr Edison’s creation.
Today they are utilized in tvs, traffic signal, car headlights, torches and also indications throughout the world.
Why should I be utilizing LED lighting?
LEDs use less power. The primarily factor for making use of LEDs is that they can take in up to 85% less energy than typical illumination. Less power taken in is good for the atmosphere however it is likewise great for service also. Less power use equals more money conserved.
LEDs last much longer. The typical age for a LED light is 10 years. Also after that they will only require changing as their light fades. Over an extended period of time their light outcome slowly dims. They can last longer too; it depends upon the application.
LEDs are much safer – LEDs utilize low voltage (12-24) volts as well as are much less of a fire threat than light bulbs as well as particularly neon lighting. LEDs emit no UV and also extremely little warmth so they can be utilized in areas where too much warmth is dangerous.
LEDs are less complicated to maintain. LEDs can be left alone and also a fast wipe over every now and then is all they require.
LEDs are strong state. There is no filament or glass to break and also they are durable even in wet problems. They can even be used undersea in some conditions.
LEDs are easier to throw away. Although there is no real way to recycle them presently they are small and also consequently much easier and much less harmful to the atmosphere than disposing glass bulbs as well as gas-filled tubing.
Best led work lights are a lot, a lot smaller sized. They can for that reason be used in a lot more creative methods than typical lights. For instance lightboxes can be slimmer, LEDs can be also be installed into acrylic panels for sure applications.
I’ve heard it is extra pricey?
Initially LEDs can be extra pricey than traditional light bulbs and fluorescent tubes however their benefits greater than remedy this. Businesses encounter power audits and also a commitment to decrease their carbon emissions, never mind the requirement to reduce costs. LEDs are part of the solution to these concerns.
What do I do with my existing lighting?
Numerous businesses believe that to update their existing lighting, as an example fluorescent tubes in ceiling strip lighting and signs, will be widely disruptive and costly. We call it retrofitting. There is a variety retrofitting LED items that can make use of existing analogue light fittings. You obtain the benefit of less power intake, reduced maintenance and also long life however you don’t have to purchase brand-new light fittings. Transforming to LEDs is as simple as changing a bulb.
What are the items available?
LEDs are made in a range of colours and tones. Straightforward electronics can manage the illumination as well as period of each LED so the impact you can get with an LED item are exceptionally varied. The market is broadening rapidly.
Easy LED modules Individual modules are generally created in banks of 4 LEDs but they also are available in a variety of different shapes and sizes and also generally escape a basic 12v transformer. They can be set up without the demand for an electrical contractor.
LEDs can be gotten ready dealt with into a sheet of plastic or run along the side of a piece of acrylic which can then be cut to fit the particular application. The limited formation of these LEDs indicates that a really even area of light can be attained.
Slimline LED lightboxes
When fluorescent tubes are positioned as well close to the front of a lightbox you usually see a striping result. Fluorescent tubes are also brief lived. If one goes you deal with a costly call out for a replacement. LEDs enable a thinner lightbox as well as a more even light for your graphics. Long life and reduced maintenance suggests that site visits are a lot less often called for. Simply an occasional wipe-over should do it!
Retrofitting non-LED products
There are now retrofitting products that just match current fluorescent and also light bulb installations. This is a short to tool term solution when you have a large amount of traditional lights, like strip lighting, and do not have the budget plan to change the fittings. You will promptly benefit from the power financial savings connected with LED illumination. One of the most usual items are fluorescent tubing replacement systems and halogen replacement area lights.

During thunderstorm, the dual thrust design of Stormking Terminal enables it to launch a faster and stronger upward streamer. This captures the lightning more efficiently and provides an enhanced area of protection. The captured lightning at a preferred point is then conducted to a dedicated earthing via low impedance conductor.
Stormking Terminals are Characterised by
Stormking terminals have dual thrust design, which results in faster and stronger upward streamer increasing the efficiency of Lightning Protection System.
Stormking terminals are made from copper and brass. The outer panels are made from Copper while central rod is made of solid brass and both are coated with chrome.
The copper and brass used are high grade pure metals. Plus they are coated with chromium for added protection against pollutants and corrosive atmosphere.
The triggering of upstreamer is non–electronic hence constant, superior performance. No battery or external power is required to activate the terminals.
The above superior features results in superior protection.

HI guys, this is the article about home equipment. I’m glad to be here and tell you something useful and interesting. To better the house functions, we will need to equip a lot of devices and appliances and it is significant to get more knowledge about them.
For security function, you will have to read more about home security camera reviews to have useful information for safety insuring. Today, I will tell you some interesting points about home equipment that you should know.
Understand A CCTV Camera For House
In terms of security camera for home, a CCTV camera has been the best type used up to the present. Considering this product, you ought to know some following points:
Styles For CCTV Camera
There are three most common styles for this camera. The first one is standard bullet style which is of the most popularity. This type has canopy and can be mounted easily on the grounds that it has a firm base. We often place in outside the house to observe things around the gate.
The second one is standard dome style. This camera is smaller than the type above and it has 180o rotating lens in order to cover all the space. This camera is often placed in the house or right in the main door.
The last one is convert camera. The camera will be disguised and the design looks like a digital watch. The lens is tiny but very effective to record images and sounds. The thieves will not know about the camera as it is hidden.
Comparison Between Wired And Wireless Camera
In the field of connection, there are two types: wired and wireless camera. Each type has its own outstanding features and you will choose the one that you think is appropriate.
The wired camera physically connects to the recorder with a coxial cable. This method works best for short distances or areas where a wireless transmission would suffer from interference.
The wireless camera uses radio frequency signals to transmit data between the camera and the receiver. Both devices are set to the same frequency and use directional antennas to increase the strength of the connection.
These two types are all good and you will not have to compare too much. You only need to understand the way they are operated and then choose the best suitable one.
Focus On The Lens Quality
It is very important to focus on the lens quality when it comes to choosing to buy a security camera. The lens should be of high quality and have resolution of 250 x 130, for example, for more clearance.
In addition to this, you should also have a good television or screen to display what the camera can record. For home security, you should have a TVL with high resolution.
These are some points about equipping a security camera that you had better know and understand in order to choose a good item for more safety. In the next part, I will help you get to know about some other devices and equipment for you house.
As said in the first part, we should choose to buy devices for houses on the basis of the different functions of the house. The part above mentions the security function so in this part, I will make it clear for daily and familiar functions.
For brightening the house, you will need to equip a good light system. In each room, the lamps and lights can be different on the grounds that the using purposes of each room are distinct. We can have some following types of lights and lamps.
- Table lamps
- Surface mounted bulbs
- Recessed lamps
The chandeliers are suitable for the living room and the dining room. Here, we need some lights for romantic and warm environment so chandelier is of the best choice. While table lamps are used when we read books or work at home. This lamp will create and spread the light within just a corner and it will not affect the other corners in the room and house.
Bulbs which are mounted on the walls are often used to brighten the stairs or for the purpose of decorating. The recessed lamps are on the ceilings in order to create magic light combination in the house.
For everyday life, we will need to buy several appliances and devices such as stoves, washing machines, fridges and some digital devices. Such equipment will better your life living.
To have a safe and versatile house, every owner needs to figure out the facilities they should purchase and consulting more home security camera reviews is necessary.. I hope that the information above will be helpful for you when it comes to equipping house devices.

I have used using Nimbuzz with my N95 in recently and it worked flalessly with my home's wireless router.Gone were the day we fumbles with microphone wires and USB cord try to make pc to phone calls using free voip provider. I have received Skype calls in New Zealand all the way from USA using Nimbuzz, the call experience was simply fantastic!
Later on I downloaded Nimbuzz, a free and great Symbian software on my N95 and again, it worked very well. My mate from the USA managed to make free VOIP to me when I logged into my Skype account using Nimbuzz.What strikes me the most is that voice call quality is crystal clear even better than the internet phone which I used before. However, I have yet to find out a solution where I can mkae free pc to landline calls.
The IP telephony is a simply wonderful thing as now I can make and receive Skype calls from my Nokia N95 whenver I am at home or at work (using the wireless router).With Nimbuzz, I can make free "PC calls" (yes, Nokia is your multimedia computer!) with using any commercial VOIP service provider. Besides that I can make phone calls free from my mobile (SKype to Skype). In this way, I need not use any expensive wireless IP phone to make SIP calls.Technically, you can make unlimited free calls using Nimbuzz or very cheap international phone calls via free internet VOIP telephony.
You can get free download through your broadband to get Nimbuzz. Now you can do without the GPRS VOIP call which you will charge by your data carrier.


Peer to Peer Networking
A Peer to Peer Network is a network where each of the computers acts
as a client and a server. No main server computer is necessary. Each computer can share their resources to other computers and also use the shared resources
of the other computers on the network. This type of network is perfect
for a network at home, because there are usually no security concerns.
It works well to give the other computers full read and write access to
your drives. To create this type of network, you must first connect your computers
with a network cable. If you are using only two computers and you are using
RJ45 (large, telephone-type) connectors on your cards, then you can use
a crossover cable. If you have more than two computers, you must buy a hub and connect the computers to the hub with a straight-thru cable. After you connect the computers you must set up the software and drivers on the computers in
order to use the network. To find out how to do this, click the appropriate link
|If you do not want to buy a crossover cable, and you have
the tools and wire to make one, find out how by clicking the link below.
