Mobile Development Platforms Comparison
Software giants, like Google are disrupting the otherwise safe and established players in the mobile application development business. Newcomers like Android have led to significant structural changes on the future of mobile application development by imposing their rules. This changed environment not only brings additional opportunities, but also adds certain constraints. Developers today, need to assess their options and find out how they can benefit from this changed environment.
While mobile computing has caught the attention of application developers, there has been very little work done to examine the programming ease of these technologies. Here we will take a look at two of the most widely available mobile development environments – Android and Windows Mobile and explore and assess these options from a developer’s perspective. visit:-https://liveenettvapk.biz/
Android was released by Google in 2007, as an open source platform for mobile software development for smartphones. The Android platform was released as part of the Open Handset Alliance. The primary aim of this alliance was to set up open standards for smartphones. Android is basically a Linux based, open source operating system for mobiles. As a mobile operating system it allows developers to create managed codes in Java, by using Java libraries developed by Google. Not only does Android provide a mobile operating system including a development environment, it also offers a custom virtual machine known as the Dalvik Virtual Machine for running applications as well as acts as the middleware in between the operating system and the code. When it comes to application development, Android facilitates the usage of 2D as well as 3D graphic libraries, advanced network capabilities such as 3G, Edge and WLAN and a customized SQL engine for continual storage.
Developed by Microsoft, the Window Mobile is an operating system for mobile devices. Based on the Microsoft Windows CE 5.0, Windows Mobile is used as an operating system on many smartphones, PDAs and touch screen devices. Windows Mobile facilitates the creation of custom written applications in managed as well as native codes. The Application Programming Interface (API) in Windows Mobile is extensible and has rich features along with a programmable layer. Besides that Windows Mobile also takes advantage of the capabilities provided by Microsoft.Net environment.
We will compare these platforms and closely examine their strengths and weaknesses. The platforms will be compared on the basis of implementation and performance aspects as well as developer support. We have chosen these criteria for the comparison as they represent the most important aspects when it comes to mobile software developers.

Beep do beep. Just passing on the latest info.


Jan 2016 – Sept 2019
My role: Interaction design
Microsoft HoloLens is the first self-contained, holographic computer, enabling you to interact with holograms in the world around you. I have been shaping the future of Mixed Reality computing in HoloLens design team since 2016 Jan by creating scenarios, IxD flows and prototypes.
I cannot reveal anything I have been doing at work on this site yet, but you can see a glimpse of my time in HoloLens design team in my Medium article, “Taking the leap from 2D to 3D”.
Also I created a HoloLens Tutorial video walking through how to create a simple projectile using HoloToolkit-Unity.


It wasn’t until 1961–when an inventor named George Devol installed his robot, Unimate, into a General Motors factory in Trenton, New Jersey–that the first modern industrial use of the robot was attempted. Unimate would lift die-cut metal pieces and stack them for the human workers. This development changed the dynamics of robotics and brought them into the workplace, making them pivotal to a business.
Automated machines have taken over the duties of dangerous and mundane jobs from humans, allowing greater productivity. Because robots never tire, extra shifts have been added to factories. Farmers have taken advantage of new technology with automated harvesters, the waste disposal industry has implemented robots in some of its dirtier jobs, and the medical industry benefits from advancements in assisted surgical robotics. The idea of a factory with no human workers has come to fruition. IBM runs a “lights off” factory in Texas completely staffed by fully autonomous robots making keyboards.
Robots’ main position in society are in a capacity to assist humans by taking on the jobs that are dirty, dull or dangerous. Beyond the factory floor, robots have been instrumental in space exploration and performing other tasks that would be impossible for humans to accomplish. The Mars rovers Spirit and Opportunity lasted years longer than NASA predicted and stayed on the mission far past the time any manned mission could have functioned. The Chernobyl meltdown site contains radiation levels that would kill any human. As such, the Pioneer robot was developed to enter the remains of the facility to address structural stability.
We offer multiple levels of robotics programs and platforms (Lego Mindstorm, mBOT, Dash and others) which are age based. The rigor of our approach and program increases as the students get older. We also support our student teams in various robotic competitions – Wonder League Robotics, FIRST Lego League.
Our robotics program covers everything related to robotics – starting from “what is a robot” to creating your own competitive robot. Learn robotic concepts, operation principles and algorithms. Students will learn scientific principles as they build multiple robots including a Line Tracer, Avoider, Battle Robot, Soccer Robot, and more.


Permanent magnet material: permanent magnet material is magnetized by an external magnetic field and its magnetism does not disappear. It can provide a stable magnetic field to the external space. There are four common measurement indicators of NdFeB permanent magnet:
The units of remanence (BR) are tesla (T) and gaussian (Gs) 1Gs = 0.0001t
When a magnet is magnetized by an external magnetic field in a closed circuit environment until the technology is saturated and the external magnetic field is withdrawn, the magnetic induction intensity shown by the magnet is called remanent magnetism. It represents the maximum flux that a magnet can provide. As can be seen from the demagnetization curve, it corresponds to the situation when the air gap is zero, so the magnetic induction intensity of the magnet in the actual magnetic circuit is less than the remanent magnetism. NdFeB is the highest practical permanent magnet material of BR found today.
The units of magnetic coercivity (HCB) are ampere/meter (A/m) and oE (OE) or 1 oE ≈79.6A/m
The reverse magnetic field intensity required to reduce the magnetic induction to zero is called magnetic coercivity (HCB) when a magnet is reverse-magnetized after technical saturation. But at this time the magnetization of the magnet is not zero, but the reverse magnetic field and the magnetization of the magnet cancel each other out. (The external magnetic induction intensity is zero.) At this point, if the external magnetic field is withdrawn, the magnet still has certain magnetic properties. The coercivity of NdFeB is generally more than 11000OE.
The units of intrinsic coerced force (HCJ) are ampere /m (A/m) and oE (OE) 1 oE ≈79.6A/m
The strength of the opposite magnetic field applied to reduce the magnetization of a magnet to zero is called the intrinsic coercivity force. The intrinsic coercivity force is a physical quantity to measure the anti-demagnetization ability of a magnet. If the applied magnetic field is equal to the intrinsic coercivity force of the magnet, the magnetism of the magnet will be basically eliminated. The HCJ of NdFeB will decrease with the increase of temperature, so the high HCJ grade should be chosen when working in high temperature environment.
Magnetic energy product (BH) in joules /m3 (J/m3) or high? GoE 1 mGoE ≈ 7.96K J/m3
The product of B and H at any point on the demagnetization curve is called the magnetic energy product, and the maximum value of B×H is called the maximum magnetic energy product (BH) Max. Magnetic energy product is one of the important parameters of the energy stored in a constant magnet. The larger (BH) Max is, the greater the magnetic energy contained in the magnet is. When designing the magnetic circuit, the working point of the magnet should be near B and H corresponding to the maximum product of magnetic energy.


Cell Phones, Mythbusters, and Selective Perception
The situation became clearer when I found a fairly detailed webbed description of the program. The people at Mythbusters were unable to get permission to actually test a cell phone in an airplane in the air--cell phones being forbidden to operate in airplanes in the air. Instead, they did two experiments:
1: A signal generator to simulate a cell phone, a navigation gauge, and various other equipment were placed inside a faraday cage (to eliminate external interference). They found that signals in the 800-900 MHz range affected the navigation gauge.
2. An actual airplane was borrowed and tested on the ground. No signal they tested had any effect on its electronic equipment. They concluded that the difference was that the electronic equipment in a real airplane is shielded, whereas in the first experiment the signal generator was more or less next to the unshielded navigation gauge.
So it is true both that they found that a cell phone had no effect on an airplane's electronics and that they found that some cell phone signals could affect the kind of electronic equipment in an airplane. I suspect that listeners selectively remembered the part of that that fit their existing beliefs and prejudices.
I also found a discussion of the issue of cell phones on airplanes, from the sceptical side of the argument, in a Computerworld article. The author thinks that both the regulators and the airlines are in favor of the ban for reasons unrelated to safety risks from interference. The article provided a link to an FCC press release which amounts to "we decided to stop our investigation into whether cell phones should be banned on airplanes because we couldn't find enough evidence to tell," which strikes me as some evidence in favor of the sceptics' view of the situation.


Online casino games and slot machines are becoming more popular because developers continue to discover new ways to improve and expand the user experience. These games are also gaining in popularity thanks to the advancements in technology. Top online slots such as slot5000 use the most advanced technology.
To ensure that you’re playing only the best slot machines, we recommend reading reviews about online casinos such as this one. You might be interested to learn more about the latest advancements in casino technology, and how they enhance the thrilling and immersive nature of online slot games.
HTML5 is the industry standard web technology
The first technology used to power online slots machines is modern web-based HTML5 technology. This technology replaces the less secure flash technology. You can play online slots in any browser, mobile or desktop, with better security. slot5000 providers have the ability to combine their desktop and mobile slot games via web-based HTML5 technology. This allows customers to sync data across multiple platforms. It is convenient to play online slots no matter where you live.
Random Number Generators
A random number generator (or RGN) is a device that makes it nearly impossible to predict the outcome of each spin. This technology keeps the game interesting and keeps players coming back for more. It is vital that it is constantly monitored. RGN technology has evolved tremendously since the days of the old pub fruit machine. Modern technological advances have improved player fairness and made it possible to provide a consistent gaming experience.
Modern slots can offer stunning visuals because many players carefully review the game’s design before they spin the reels. No one plays a slot and immediately thinks about volatility or random number generators. The game’s appearance is what they focus on most. It should be stunning. Also, consider the volatility and RTP. A stunning slot machine is more than just the graphical design. Technologies like 3D modeling, storytelling, illustrations, and illustration influence the game’s visual style. Game developers must work together to produce a final product.
Virtual Reality Slots
One of the most important trends in casino slots is virtual reality (VR) technology. Virtual reality technology is becoming more popular, with applications ranging from robots and online casinos. VR allows the user to enter 3D scenes that are more realistic and immersive than those created on a screen. Virtual reality gaming is available at some online casinos and will continue to grow in popularity.

Enabling Home LAN will allow you to communicate between two computers and hence share or transfer files at a very fast rate (varies according to your Ethernet card speed) and also it enables you to share the internet connection between two computers. If you have two or more computers at home, then it makes sense to have them on a network. Setting up a home network is no longer a tedious task once you go through our following tutorial.
Things you’ll need:
At least 2 computers
Ethernet Cable: you can buy it from the local computer parts shop
Wireless router: this may be optional if you only want to network between two computers.
Ethernet card with driver installed on both of your computers
First of all run network configuration wizard on both computers by going to Start->Control Panel->Network connections and click on Set up home or small office network. (see below)
Click next and then follow the screenshots: (see below)
Click Next (see below)
Check on Ignore disconnected network hardware and choose your Ethernet adapter and then click next. (see below)
Choose the appropriate connection method. To connect two computers check on the second option, This computer connects to the Internet through a residential gateway or through another computer on my network. If you want to share the internet connection between two computers as well then select the first option, This computer connects directly to the internet. The other computers on my network connect to the internet through this computer.
For better understanding click on View an example link.
Type in your computer description (optional) and computer name then press Next.
To get the name of your computer accurately, go to Startà right click on My computerà Properties à Go to Computer Name Tab
Note the Full computer name, in my case it’s SAAZ-117D10A6F5 and also the WORKGROUP, it’s usually MSHOME.
Leave the workgroup name MSHOME (by default) and click Next
Set file sharing ON if you want to share files with other computers in network. Then click Next.
You’ll be provided the details you entered after the above procedure: (see below). Make sure that everything is ok and click Next.
Select Just finish the wizard: I don’t need to run the wizard on other computers and click Next.
Click Finish to complete wizard. The system may ask to restart your pc to load the extra drivers needed for LAN Communication.
And you are done by setting up connection between two computers.
To connect with more than two computers, the basic principal stays the same. Simply make sure that all the computers you want to set up in LAN are connected on a network via hubs, switches, etc and then simply assign a different IP Address to each machine. Just make sure that they are all on the same Subnet Mask.
Note: Usually you don’t need to enter IP Addresses and you don’t need to restart computers to make network connection in windows XP platform.
However if you need to set up the IP addresses of two computers follow these steps:
Setting up different IP addresses
Now you will have to set IP addresses on computers. You can do this by going to Start->Control panel->Network connection and right click on Local area Connection icon and left click on Properties.
In the list find Internet protocol (TPC/IP) select it then click Properties.
In the box check on Use the following IP address and set IP address and Subnet mask. IP address by default can be 192.168.0.1 and Subnet Mask 255.255.255.0. Make sure that the fourth number section of IP address is different on each computer.
For example, if first computer’s IP: 192.168.0.1 then the second computers’ must be 192.168.0.2.
Then click Ok.
Restart both computers if needed. Now you made network between two computers.
Now you can connect both or multiple computers.
Hope it helped you.

- An analog/mixed mode design depends primarily on the cleverness of the designer and the limitations of the process. Simulation is used to verify how well these things have been optimized against the specification. I suppose one can't have too much simulation, but having an engineer sit for months verifying a design can add considerable cost to the effort. We try our best to verify the design as quickly as possible to ensure cost and schedule.
- Do we need a simulation plan? - Often a pre-agreed set of simulations to prove a design can be helpful. While we always want to run full process corner simulations on every design over every temperature and operating voltage, the set of simulations this requires can be enormous. If the chip is large and the simulations take days or weeks, the implications to cost and schedule are obvious. Lets work together up front to determine what's really needed. If you need every simulation, it's fine with us.
- We use 64 bit Smartspice (Silvaco) for analog simulations and mixed mode simulations where extreme accuracy is required. It can also handle very large circuits. The 2 processor cpu architecture also increases speed.
- Mixed Mode simulations are done using Smash (Dolphin) This simulator is very handy where the logic can be described by vhdl and at the same time very accurate analog simulations can be accomplished.
- Both simulators can be used for full chip simulation.
- Very often design, simulation, and layout can overlap in the schedule. Since this is so, MTE often subcontracts layout with highly qualified subcontractors. This is part of our successful "virtual" company approach. This allows us to address any job, no matter how large. It also allows us to address shorter development schedules than many chip contractors can.
- Our internal layout tools are from Stabie-soft. They have a great layout editor called Slam, which has an integrated lvs and drc capability.
- Should final verification with Calibre or other such high end verification tool be a requirement, this can easily be subcontracted with the layout. This keeps our internal overhead and costs down.

I’d like to create a minimal Rails project that can display a chart. The first tutorial I’ve got to work for me is called Charts with Chartkick and Groupdate. I’m going to pick it apart and turn it into a bare-bones how-to. Continue reading “Rails Charts with Chartkick”
My Conditions project has two wireless “conditions” sensors sending air temperature and humidity to a Rails server every minute. Now I want to display the current temperature and humidity on a CharlieWing. The first task is to get the Rails server to stop dumping the entire history of temperature readings into the JSON file returned when I request it. I’d like to implement this with URL parameters so I can request (for example) http://192.168.2.2/measures?station=1&limit=1 but my attempts so far have failed. As usual, I’m going to put my pedant hat on and get this right.

How to take your van conversion to the next level with smart devices to make van living and travel more enjoyable
Why does the minimalist life have to come with compromise?
Why can’t we simplify out life in the van and on the road as well? Automate the simple things and make life that little bit easier? That’s what we have striven to achieve in our van build. To not only make it a home, but make it a smart one too.
Now this is significantly easier than you may think with the use of some handy little contraptions.
A minimalist life is life simplified and that goes with our technology too. Our electric hot water service switches on 45 minutes before my alarm for work so that I can have a hot shower first thing in the morning without wasting the power to keep it running all night.
All our lights are automated or can be (there’s always personal preference in a custom build). We are able to choose the colour of light (like red for keeping night vision) and mean we can wake up without harsh, white light, directly in our eyes.
Most of our basic electrical appliances are interconnected to create simplicity and practicality, the core of all our builds.
The brains behind our smart gadgets are 2 main products; our Google Home Mini and our RVWiFi 4GX.
The Google Home is how we create our routines and alarms and the RVWIFI is what connects all the dots by creating a WiFi network inside and around our van as well as giving us cell service and enhanced reception.
Now lets dig a little deeper into the smart gadgets we have used. Two convenient and extremely easy to install gadgets that we included; are our LED Strip Lights and Magic WiFi chips. Magic WiFi chips plug directly into your LED Lights and connect them to your WiFi to control the colours and patterns as well as brightness of your lights.
For 12V appliances and our LED down lights we use a Sonoff 12V WiFi Chip. This little gem costs about $10 and integrates seamlessly into your existing wiring.
These intelligent little chips are a breeze to install, simply connecting inline with the positive and negative wires of your lights. They are worth their weight. We have one of these chips wired to the switch wires of our Duetto Mk2 12v Hot Water Service so we can heat the water for a shower 45 minutes before our morning alarms go off.
With these additions to your electrical system (especially if you are considering eliminating gas from your build design), you will feel as though you never left luxuries behind. Why not be minimal and make your build smarter, not harder?

Even if many similar designs exist, Smart & Green’s LED lighting incorporates unique, high quality technology, making our products remarkably different:
The basic concept of Smart & Green is the standardization of LED light bulbs: whether stand-alone or with a diffuser you’ll have no trouble finding a place for them in your surroundings.
The sky’s the limit when it comes to creating an ambience thanks to the easy availability of all the colors of the rainbow or just white.
Simplify the lighting around you by using Smart & Green’s LED lamps safely anywhere, anyhow.
If you’re playing in the pool, take it with you … but what if it falls? Don’t worry, it comes out tops in the most stringent tests!
Your cordless lamp can go with you everywhere and will last a long time. Lithium-polymer technology means the battery has a long life, and allows you to recharge your lamp whenever you want.
But the real luxury is not just that there’s no power cord – you can also control all your lamps at a distance with one touch of a button.


Developing a custom SoC based on an ASSP with a proven track record in the market not only makes it easy to design the components surrounding the CPU and the subsystems. It also has the advantage of easier development and evaluation because related software is also already provided.
From our experience of ASSP-based design for our product, the development period was achieved six months shorter than the development period by conventional design. This rapid time-to-market was achieved by shortening hardware design period and by developing software in advance.
- Delivery time of sample SoC : Six months ahead of schedule
- Advance development of software : Eight months ahead of schedule
- Product shipping : Six months ahead of schedule
This section introduces one example of ASSP-based development.
①Extracting necessary application IP from ASSP
We extract application IPs which are required for customer's development from our proven ASSP.
②Combining base platform and extracted application IP
After cutting down unnecessary IPs and Interfaces from base platform, then we combine this optimize platform and extracted application IP.
③Adding your special functions to differentiate from others
By adding your special functions to differentiate from others, your special SoC design is now created.
④Evaluating and verifying functions, performance, and power
The functions, performance, and power can be evaluated and verified using a dedicated hardware emulator at approximately 1000 times as fast as an HDL simulator.
For your software development, we provide a prototype environment such as an FPGA board and CPU board. This allows customers to develop software before manufacturing SoC.
⑤PCB (printed circuit board) co-design
Implementing high-speed components (DDR, PCIe, USB, etc.) and SoC on a PCB tends to cause a electrical issue such as electromagnetic noise, crosstalk, and clock jitter. We analyze such issue creating PCB prototype and offer proposed measures.
This reduces risk associated with developing a PCB and thereby reduces cost for PCB design and manufacturing.


4 in one camera
4 in 1 Cameras
4-in-1 cameras can be changed to Analog, TVI, CVI, and AHD. One camera has four different technology
Analog, TVI, CVI and AHD.
Most have a button on the cable like in the picture, hold for 5 seconds and move left/right/up/down to change. These cameras have BNC female and power input usually 12V DC.
Don't need to worry if the DVR supports the camera; change to desired option with the flip of a button on the camera cable, no tools needed. Even better if you DVR is Analog it will work now as Analog camera. When you purchase an AHD, HD-TVI or HD-CVI just change the mode to HD.

Hi, Im looking for some help with a few questing im stuck on with my study, If anyone can help would be much appreciated....
1, What is the RS-232 interface on a printer also known as?
2, On an AT Motherboard what is the data bus whidth of an ISA slot?
3, On an ATX Motherboard how wide is a 72-pin SIMM memory slot?
15-01-2008, 08:34 PM
1. Parallel port, usually DB-25 (very rarely not).
3. I have no idea, do you mean physical width (as in millimetres)?
15-01-2008, 08:45 PM
RS-232 is a serial port, not parallel.(typing this in wikipedia takes two seconds and you have the answer straightaway)
15-01-2008, 09:32 PM
Meh, I saw printer and that was the first thing that came to mind, since printers use parallel ports >.>
15-01-2008, 09:49 PM
Especially the earlier generations of Apple printers were all serial, and modern day printers use Univeral SERIAL Bus, so hardly all of em ;)
15-01-2008, 10:18 PM
Unfortunately mid-life Apple printers weren't specified in the question and USB is not an R* type interface. IBM PCs used LPT ports for printers and as far as I can remember Serial printers are about as rare as they come (as in practically non-existant)
Apple printers were all parallel printers until 1984. After that, there was a short reign of serial printers up until around 1992 when they started producing SCSI printers as well.

The nominal voltage of a lithium iron phosphate battery is 3.2V, and the full-charge voltage is 3.65V. Put another way, a lithium-ion battery's practical use-related potential difference between its positive and negative electrodes cannot be greater than 4.2V due to material and use safety regulations.
The car and its accessories are powered by the HV battery. The HV battery's charge level may progressively drop when the car isn't being driven or charged. When the car is kept in hot weather and is briefly parked in cold weather, the HV battery's capacity may gradually decline.
Lithium-ion Batteries: Unmatched Energy Storage Capability Lithium-ion batteries excel in energy storage, boasting the highest energy density among all battery cells. Compared to alkaline batteries, they possess a superior capacity for storing energy. Moreover, lithium-ion batteries are available in three commonly used sizes: AA, AAA, and 9V. Notably, their milliampere-hour (mAh) ratings outperform those of any other non-rechargeable battery technology.
Size restrictions have been put in place for lithium batteries. For non-rechargeable lithium metal batteries, the lithium content per battery is limited to 2 grams. As for rechargeable lithium ion batteries, they are restricted to a maximum energy rating of 100 watt hours (Wh) per battery. These limitations encompass the majority of lithium batteries commonly used in electronic devices by everyday individuals. This regulation will be effective until March 15, 2023.
A limited range of useful energy is provided by 12-volt batteries, ranging from over 14 volts (when fully charged and not in use) to 10.5 volts when being utilized or under load (resulting in dimming lights, groaning pumps, and shrinking TV pictures). It is important to note that a 12-volt battery cannot sustain a voltage over 14 volts for more than a few seconds unless it is undergoing charging.
For AGM or certain types of flooded batteries, the desired voltage range for a 12-volt charger is between 2.4 and 2.45 volts per cell, equivalent to 14.4 to 14.7 volts. It is worth noting that some flooded cells have the capacity to withstand voltages exceeding 15 volts.
Overall, appliances operate slightly better because to the increased voltage. A high energy density is another feature of high voltage batteries. They have a longer battery life while giving more power since they can give higher capacity under the same usage conditions.
To boost the voltage across a battery's terminals, one can arrange the cells in a sequential order known as "series". This entails aligning the cells one after the other, linking the anode of one cell to the cathode of the next. Through the act of connecting batteries in series, the overall voltage is elevated.
Voltage is a measurement of the energy stored in a battery, while amperes quantify the level of electrical current. Batteries bearing higher voltages are compatible with cordless tools that possess greater power, and they furnish the necessary energy for high-torque applications. It is worth mentioning that certain battery varieties experience a decline in voltage as they discharge, whereas others tend to remain largely stable. This observation was made on June 2, 2016.
Lithium-ion batteries, known for their immense power, also possess the potential of being highly explosive. Repeated recharging of these batteries may give rise to dendrites, which in turn can initiate a short circuit and lead to the battery erupting into flames. This phenomenon has been observed as of March 9, 2021.

I experimented with a 200A rated smaller black square CB. It reached a significant temperature and tripped at 125A. A different one rated at 250A was tried; not much better. This is the one I purchased and mounted in my travel trailer. It stayed closed at 200A despite being more expensive and larger, and after roughly 20 minutes, it tripped at a higher amperage. This one trips as anticipated and doesn't overheat. I am rather confident that this device will open at the proper current to protect the electrical system without posing a fire risk, unlike the cheapies I tried.

Printed circuit boards, or else known as PCBs, are primarily the mind or heart of every digital tool. A PCB can be viewed as the center through which a digital gadget obtains its info as well as does the tasks which it was developed for.
Printed circuit boards have been in usage for over a century as well as modern PCBs have been around for over HALF A CENTURY. These digital components have actually essentially changed the entire manner in which the globe features.
These circuits are positioned inside nearly every digital tool and also they have actually enabled the globe to become just what it is today. Modern technology has become more and more common because of these little boards, and electronics have progressed by an amount many people did not consider feasible. These days, it is not unusual to see a kid controling an electronic device with specialist grace and simplicity.
Printed circuit boards include an extremely great portion of steel that is superb at performing such as copper. Copper is just one of the most common materials made use of to earn a motherboard. These slim and also fine pieces of copper are engraved with the design as well as format that was previously prepared by the designers. Printed circuit board layout frequently contains plastic and also having copper etched right into them for maximum conductance.
There are 4 major layers to a PCB. The top layer is the silkscreen, as well as this screen is what contains all the numbers and also letters which are visible. The silkscreen is essential due to the fact that it assists human beings like us much better understand just what each part is made use of for as well as how to utilize this particular board.
The 2nd layer is a solder mask which assists to insulate everything as well as provides the eco-friendly tint, adhered to by a slim layer of copper. The thickness of the copper layer actually varies depending on the item and its needs. The last as well as bottom layer makes up most of the density as well as consists of the substratum. Fiberglass is a website typical substrate that is made use of.
Planning out the style and design of a board could be an extremely difficult as well as difficult job that is frequently just done by specialists. Newbies and experts alike could highly take advantage of the use of on the internet software program that helps with the whole preparation and creating procedure. Creating a design for circuits is not specifically a very easy work, and that is why software application could assist a whole lot. Not only can software application assist with the format, but they can likewise explain blunders and help one find out options to feasible twists in their strategy.
The work of the board itself is to sustain and also attach all the differing digital parts that compose the PCB.

Owning an electronic gadget means that there bound to be some problems that might arise at some point or the other. Especially when there are costlier gadgets like iPhone’s, it is essential to see to the proper functioning of its system so that everything turns out to be just perfect. Therefore, taking care of the innovative electronic device needs to be done with utmost clarity and thus, there are might one or more reasons to get that iPhone repaired. Thus, the 6 main important reasons as to why your iPhone needs to be repaired are as follows:
- Serious battery issues
One of the important issues that usually grip all of the iPhones is that it can have serious battery problems. This can totally be really costly and therefore, the repairing service should be availed as soon as possible. However, it is only under the guidance of the experts that the repairing must be done and therefore, it can be used normally as usual.
- Broken screens
One of the most serious damages that usually occur when one has an iPhone with them is that the screens once damaged, can really be costly to be repaired. Most of the iPhone screens are made of nanotechnology that prevents the scratching of the phone and therefore, its repairing is done keeping in mind all of the respective and individual cases. Therefore, it is really essential to carry the phone around with utmost simplicity and carefulness so that it doesn’t get damaged in any way possible.
- System damage
One of the fewer damages that handicap the iPhone is that the system gets damaged sometimes and this can really harm the phone if it is not taken to the service center. Thus, on seeing to the system settings, one can likely get in touch with the best possible setting options and this can bring in fewer damages too.
- Touch screen not working
When going to theiPhone service center in Mumbai, it is good to see the fact that the touch screen can be repaired as well if it is not working. This can totally bring in some extra costs, but the screen damage needs to be repaired urgently or else the phone is of no use.
- No signal
Most of the iPhone service center in Thane helps in the repairing of the iPhone’s if there is no signal. Such a problem seems to be very common with all of the iPhone models and therefore, if one gives the phone to some professional service centers, then it might get repaired overnight.
- The camera is not working
One of the fewer reasons as to why the iPhone needs urgent repair is that the camera is not working at all. In such a condition, one can likely give it at the mobile repair service and the experts there can help in the camera problem to be perfectly fine again.
Thus, if any of the above problems arise, it is time to get the iPhone repaired.

Tech Peek | 5G & Manufacturing Technology
5G mobile phone networks make all the headlines — who wouldn’t like to download a two-hour movie in 10 seconds — but some of the first “killer applications” for 5G will be in manufacturing. The inherent nature of the factory – a controlled environment – addresses 5G’s biggest shortcomings while promising a decent return on a comparatively limited investment. In fact, the factory of the future has been waiting for 5G to call. Industry stands on the cusp of implementing what experts call “massive machine-type communications” with billions of connections. 5G will act as the catalyst. Here are seven reasons why the technology will transform manufacturing.

Athens, GA summers are humid and hot. You need an air conditioner that can handle the heat. Ductless AC is flexible and energy-efficient. Here’s why a ductless AC mini-split system could be just what you need:
Ductless AC Has Outstanding Energy Efficiency
The SEER of an air conditioner indicates how efficiently that system will perform. The minimum SEER is 14. Mini-splits have SEER ratings of up to 30.5. Ductless AC also has advanced inverter technology. It runs on high speed to achieve the initial thermostat setting. When the desired temperature is reached, it maintains that temperature by making small adjustments in output using only the energy that’s needed.
An outdoor unit is connected to one or more indoor units by way of tubing. Each indoor unit controls conditions in a separate room or zone. Indoor units have their own thermostats, so you can cool one room without cooling the others.
Many Athens homes lose up to 30 percent of cooled air through leaky ducts. That keeps utility bills high and overworks your air conditioner. Ducts also collect contaminants that can be hazardous to health and damaging to your air conditioner.
Healthy Indoor Air
Mini-split air conditioners have cutting-edge air filtration capability. Indoor air is always circulating through the system, so contaminants are filtered out. Ductless air conditioning can remove up to 99.9 percent of indoor air pollution. Because mini-split systems run at multiple speeds and stay on longer, they remove indoor humidity as well.
These units are easy to maintain, easy to install and feature virtually noiseless operation. Mini-split AC systems can be installed in just one room, in several rooms or throughout the whole house. At Kovack Mechanical, Inc., we have the experience and expertise to correctly size and install these high-tech systems. Call us at (770) 892-6986 to learn more.


We live in unusual times. Even before a trio of bubbles could fully deflate, we are in another one. This time it is artificial intelligence leading the charge. To understand just how much of this is being driven by hype and if there is enough substance below the surface, I reached out to a friend who has a Ph.D in Computer Science with a focus in AI from Carnegie Mellon University and who has been an operating an AI company he founded more than six years ago. Before starting his company, he was the Lead Data Scientist at a Fortune 500 firm.
He mentioned that generative AI tools like OpeAI’s ChatGPT and Google’s Bard have been transformational for the industry and many in the field had not expected such rapid progress.

Corsair Virtuoso RGB Wireless
The Corsair Virtuoso RGB Wireless is the new flagship headset from Corsair. Super high audio quality with 7.1 surround sound, customizable RGB lighting and a detachable microphone! The Virtuoso comes in two different versions, the regular Virtuoso comes in two flavors, black and white. And then there is also a special edition of the Virtuoso RGB Wirelesss headset with a brushed metal finish, improved mic and it also comes with a storage pouch!
The normal Virtuoso RGB Wireless comes with a price tag of $179.99 MSRP, the Special Edition goes for a price of $209.99 MSRP.
- Sound quality: 50mm speakers with a frequency range of 20Hz-40,000Hz.
- Comfort: Premium foam earcups and a lightweight pillow-soft headband.
- Versatility of connectivity: Can be wireless (up to 60ft signal), USB wired, or 3.5mm wired (so you can connect to PC, XB1, PS4, Switch, Mobile)
- Xbox One
- Nintendo Switch
- Wireless (Slipstream Corsair Wireless technology)
- Detachable microphone (omnidirectional mic).
- 20+ hours battery life while in wireless mode RGB lighting
- Smart Sleep and Wake Mode
- RGB Lighting
The Normal version of the Corsair Virtuoso RGB Wireless contains: Headset, Wireless USB Adapter, Charging Cable (1.8m), Aux Cable (1.5m), Guide.
I used the Virtuoso RGB Wireless headset for several days before I made my second part of the video review. It really fit well on my head and the premium foam earcups made it a charm to wear. I often have issues that headsets are a bit too heavy and then apply pressure onto my glasses which sometimes leads to headache. With the Virtuoso RGB Wireless I tested both my normal glasses and the special gaming Gunnar glasses which have a thicker case that can cause issues, I had none with this new headset. The coolest feature for the headset is the detachable microphone, for me as a content creator I usually use an expensive external microphone, in my case the Rode NT, so I do not need the mic. Now with this headset I can simple detach it so it doesn’t get into my way or is annoying. Now just make sure not to lose that thing!
With such a hefty price tag you also expect performance and quality. The Virtuoso RGB Wireless comes with 50mm speakers with a frequency range of 20Hz-40,000Hz, that is basically double what most gaming headsets have. During my review of the headset in the video I also tested out the microphone and the quality is superb! The cool thing about this headset is also, that you can use it to listen to music on your phone, because it comes with a 3.5mm audio cable that you can plug in everywhere, so it is not limited to gaming.
The design is nice and the materials that are used are high quality. I also like the RGB lighting that I can modify in the software alongside with the many modifications I can make. Within the software you can turn of certain features like the light on the mic, which can cause slight distractions otherwise while gaming, so I was happy I could turn it off. You can also set a sleep mode timer, that way the headset will automatically turn off once you don’t use it anymore.
Whats in the box?
The box comes with the Headset, Wireless USB Adapter, Charging Cable (1.8m), Aux Cable and a Guide. If you ordered the special edition you also get a storage pouch. The USB Adapter can be plugged into your PC or Console of choice, the Charging Cable is 1.8 meters long and can be plugged into any USB plug to charge your headset. The Aux Cable is also a nice addition, in case you want to use the headset to listen to music on your phone or through a mixer (like I usually do when I stream).
Like always you can adjust settings for the headset in the ICUE Software from Corsair.

We describe an importance sampling method to generate samples based on the product of a BRDF and an environment map or large light source. The method works by creating a hierarchical partition of the light source based on the BRDF function for each primary (eye) ray in a ray tracer. This partition, along with a summed area table of the light source, form an approximation to the product function that is suitable for importance sampling. The partition is used to guide a sample warping algorithm to transform a uniform distribution of points so that they approximate the product distribution. The technique is unbiased, requires little precomputation, and we demonstrate that it works well for a variety of BRDF types. Further, we present an adaptive method which allocates varying numbers of samples to different image pixels to reduce shadow artifacts.

Water meter hardware is mostly sold for residential use.
Meter reading can be done remotely by sending an RF signal to the water meter. The water meter sends back a data packet containing the amount of water used so far during that billing cycle, and it will also encrypt this information so that only the utility company can read it.
The residential smart water meters are designed to work in residential “single family homes” and their readings are done using both the utility power lines and the customer’s own AC wiring. In order for this to work, there needs to be a power connection going from the residential home up to a transformer that is connected to the utility power lines.
This transformer then provides a second AC output which can be put on the residential home’s existing AC wiring. A smart water meter will use this 2nd AC input in order to communicate back and forth with the residential home’s company (the residential “home-owner” utility).
The residential smart water meter will put out a carrier signal that is then detected by the residential home’s power company. The residential power provider has a “box” which detects this carrier signal coming from the customer’s home, and it will send back an answering signal. That residential smart water meter will read the residential power company’s signal, and send back a response with some encoded data in it.
The residential power provider “box” detects this answer, retrieves the information from it, and then sends this information on to the residential smart water meter’s software which will record the amount of money that is owed for using that supply of residential water. The residential power provider “box” can also send out commands to the residential smart water meter, telling it what settings to use for billing or how much residential power to take.


Geographical Information System has three important components: computer hardware set of application modules and a proper organization context.
A working GIS integrates five key components: -
Computer Hardware Module: The general hardware component of a geographical information system is the computer or central processing unit.
Computer Software Module The GIS software includes the programs and the user interface for driving the hardware. GIS software is essential to generate, store, analyze, manipulate and display geographic information or data. A good GIS software requires user friendliness, functionalities, compatibilities, updatability, documentation, costeffectivness. The following is a list of GIS software producers and their main products.
- Environmental Systems Research Institute ( ESRI ): ArcInfo, ArcView.
- Autodesk: AutoCAD Map
- Clark Labs: IDRISI
- International Institute for Aerospace Survey and Earth Sciences: ILWIS
- Mapinfo Corporation: Mapinfo.
- Bentley Systems: Microstation.
- PCI Geomatics: PAMAP
- TYDAC Inc. : SPANS
Data Data is the most important component of a GIS. Geographic data and related tabular data can be collected in house, compiled to custom specifications and requirements, or purchased from a commercial data provider. A GIS can integrate spatial data with other existing data resources, often stored in a DBMS. The integration of spatial and tabular data stored in a DBMS is a key functionality afforded by GIS.
People GIS technology has limited value without the people who manage and develop plans for applying it to real world problems. GIS user range from technical specialists who design and maintain the system to those who use it to help them perform their everyday work. The identification of GIS specialist's vs. end users is often critical to the proper implementation of GIS technology. This is what called 'brain ware' which is equally important as the Hardware and software. Brain ware refers to the purpose and objectives, and provides the reason and justification, for using GIS.
Method A successful GIS operates according to a well designed implementation plan and business rules, which are the models and operating practices unique to each organization.
For many years, though GIS has been considered to be too difficult, expensive, and proprietary. The advent of graphical user interface (GUI), powerful and affordable hardware and software, and public digital data has broadened the range of GIS application and brought GIS to mainstream use.

What is the difference between half and full duplex?
Half duplex mode is a two-way directional communication but one at a time.
Full duplex mode is a two-way directional communication simultaneously.
In simplex mode, Sender can send the data but that sender can’t receive the data..
Is 10base full duplex?
Half duplex Ethernet 10BASE-T technology restricts the media to having one channel for transmit and receive. … In the event that these two hosts were communicating in a full duplex 10BASE-T Ethernet environment, the two hosts would have two channels, separating out transmit and receive.
What causes half duplex?
A duplex mismatch occurs when two devices connected by Ethernet do not properly negotiate their connection. Ethernet has the option of running at different speeds (10, 100, or 1 Gbps) and has the option of running half duplex or full duplex.
Does full duplex double the bandwidth?
Full-duplex operation doubles the theoretical bandwidth of the connection. If a link normally runs at 1 Mbps but can work in full-duplex mode, it really has 2 Mbps of bandwidth (1 Mbps in each direction). … However, you certainly get better throughput than in a half-duplex mode.
What is duplex setting?
LAN Switches One of the most basic settings of a switch is the duplex setting of each individual port connected to each host device. … There are two types of duplex settings used for communications on an Ethernet network: half duplex and full duplex.
Can there still be collisions in a full duplex Gigabit Ethernet Switch?
The collisions are possible on an Ethernet network where all host share the same carrier medium. … In full duplex, the Tx and Rx medium (separate copper wires of same cable) and therefore there would be no collision. Example would be a PC connected to a Switch Port.
Is Bluetooth full duplex?
half-duplex communication, or full-duplex communication. Bluetooth can send data at more than 64 kilobits per second (Kbps) in a full-duplex link — a rate high enough to support several human voice conversations.
Is full duplex faster than half duplex?
It’s not. Half duplex is half the speed of full duplex, because only one end can talk at a time. Wireless networking is typically half duplex.
Is Ethernet full or half duplex?
Legacy Ethernet is half-duplex, meaning information can move in only one direction at a time. In a totally switched network, nodes only communicate with the switch and never directly with each other.
Can is full duplex?
RDM and CAN bus are examples of this type of service. This is sometimes known as two-way alternate, denoting that nodes take it in turn to transmit. Nodes that are not transmitting generally act as receivers. Full Duplex: Many data networks transfer data in two directions and are known as duplex communications links.
What is required for full duplex?
The following requirements, as stated in the 802.3x standard, must be met for full-duplex operation: The media system must have independent transmit and receive data paths that can operate simultaneously. … Both stations on the LAN are capable of, and have been configured to use, the full-duplex mode of operation.
How do I change to a full duplex?
Configuring Speed and Duplex in Microsoft* Windows*Navigate to the Device Manager.Open Properties on the adapter you would like to configure.Click the Link Speed tab.Select the appropriate speed and duplex from the Speed and Duplex pull down menu.Click OK.
What speed and duplex should I use?
If the speed is 10 or 100 Mbps, use half duplex. If the speed is 1,000 Mbps or faster, use full duplex.
Is TDD a half duplex?
Time-division duplexing (TDD) is a method for emulating full-duplex communication over a half-duplex communication link. The transmitter and receiver both use the same frequency but transmit and receive traffic is switched in time.
What is the example of full duplex?
In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is plain old telephone service; the parties at both ends of a call can speak and be heard by the other party simultaneously.
What are the benefits of using full duplex?
Speed. Speed is a big advantage of a full duplex network infractructure. When a device is set at half duplex, it can receive and transmit data, but not at the same time. With a full duplex network environment, that data can be sent and received at the same time.
Is WiFi full duplex?
A wired Ethernet network is full duplex, meaning a device can send and receive, or upload and download, simultaneously. WiFi is half duplex, so if a client is sending data to the AP(Access Points), the AP can not also send data to the same or any other client at the same time.
Why is full duplex better than half duplex?
Full-duplex Ethernet does save time when compared to half-duplex because it alleviates collisions and frame retransmissions. Sending and receiving are separate functions, creating a system where there is full data capacity in each direction. In contrast, half-duplex can be used to conserve bandwidth.
Are cell phones full duplex?
A cell phone is a full-duplex device. That means that you use one frequency for talking and a second, separate frequency for listening. Both people on the call can talk at once. Channels – A walkie-talkie typically has one channel, and a CB radio has 40 channels.
Is 4g full duplex?
Re: Why can’t WiFi work as full duplex while 3G and 4G can. Not only Wi-Fi cannot work as full-duplex, but also two or more devices cannot transmit or receive traffic simultaneously. Unlike 3G/4G, Wi-Fi uses unlicensed frequencies in the spectrum, which simply means you do not have to pay for using them.
Is LTE full duplex?
It is one of the two mobile data transmission technologies of the Long-Term Evolution (LTE) technology standard, the other being Long-Term Evolution Frequency-Division Duplex (LTE-FDD). … The LTE-TDD spectrum is generally cheaper to access, and has less traffic.

Post From: DTC C# Client
|Adam Burgess - Posts: 1 | Ending Date: 2019-09-02 [Expired]|
I have been working on accessing Sierra Chart data feeds from an external application using C#. My skillset doesn't really extend into the sort of C++ programming that I'd need to understand in order to build a native interface using the provided header files. There are some old C# samples around the place but nothing that was really even close to what I was chasing. There were even a few people claiming to have done this, but no code was provided.
So I ended up writing a C# interface into DTC that is currently providing some of the connectivity that I wanted, although it's definitely still a work in progress.
- That project isn't (and was never intended as) a complete DTC protocol handler for every possibly message type.
- There is a sample client that can be used for functional testing.
The source code has been made publicly available under an MIT License at https://github.com/QANTau/DTC-Client.
Sharing this in the hope that it's useful to others.
