The SL1 is meant to be attached to submersible sensor-laden research robots known as profiling floats. These devices collect data during short trips as far as a mile beneath the surface. When they emerge from the depths, they beam that information to a satellite. Today, there are thousands of profiling floats drifting through Earth’s oceans as part of an international program called Argo. They remain the best tool scientists have for remotely studying the upper ocean, but their life span and data collection are severely limited by their power sources.
All the floats in the Argo fleet are powered by lithium-ion batteries, which are typically only good for about five years or a few hundred dives. Their battery reliance limits how often they can dive; a typical float only does it once every 10 days. And after its battery dies, a float is usually abandoned, because the cost of collecting it is higher than the cost of the device itself. Still, a float can cost as much as a new car, which makes them expensive pieces of jetsam.
“Anything we put in the ocean is limited by its battery,” says Steve Jayne, a senior scientist at Woods Hole Oceanographic Institution, who isn’t involved with Seatrec. “If you had unlimited energy available to you, you might be able to profile every day instead of every 10 days.”
Seatrec’s ocean generator doesn’t produce a lot of energy—each charging cycle tops it up with about half the energy of a single AA alkaline battery—but that’s more than enough to meet the needs of the low-powered sensors typically found on profiling floats. For applications that require more power, Chao says, it’s possible to increase the size of the generator or simply daisy-chain smaller ones together. The floats are also designed to work in any ocean environment, whether they are trapped among Arctic ice floes or diving among sharks in the tropics. All it takes to adapt them to different regions is tweaking the chemistry of their waxy guts so they solidify and melt at the correct temperatures.
Chao hopes that Seatrec’s ocean generator will deliver on a promise first conceptualized in the 1980s by the renowned oceanographers Douglas Webb and Henry Stommel. They envisioned a globe-spanning fleet of missile-shaped underwater research robots called Slocum gliders that would explore the oceans with the same dexterity, autonomy, and longevity that we’ve come to expect from the robots that NASA sends to explore other planets. Like Seatrec’s SL1, these gliders would be powered by underwater temperature differences.
Although Webb, Stommel, and their collaborators made progress toward bringing a global fleet of Slocums into existence, their vision is still a work in progress, says Matt Palanza, a program engineer at the Woods Hole Oceanographic Institution’s Ocean Observatory Initiative who previously worked with Webb. Palanza’s team at the Ocean Observatory oversees the largest civilian fleet of Slocum gliders in the world—50 in total—and he says the reason there aren’t thousands patrolling the world’s oceans is simply a lack of funding. “The technology is there and continuously being developed,” he says.
Chao and the team at Seatrec believe that extending the vehicles’ life spans with limitless clean energy could drastically increase the size of the ocean research fleets. But the company isn’t the first to work on the technology. In 2003, Webb built a prototype thermal glider that used temperature differences to control its ascent and descent in the ocean, but still relied on batteries for its electronics. In 2008 a team led by researchers at Woods Hole successfully deployed a different glider prototype in the Carribean that used ocean temperature differences to power an electric propulsion system. The following year, Chao and a team of researchers from NASA and the Scripps Institution of Oceanography rolled out Solo-Trec, the world’s first profiling float powered completely by electricity generated from temperature differences.


Ethernet cables is wired as straight through or crossover. The straight through is that the most typical kind and is employed to attach computers to hubs or switches. they’re presumably what you’ll realize once you visit your native store and obtain a patch cable. Crossover coaxial cable is a lot of ordinarily accustomed connect apc to a computer and will be a touch tougher to search out since they aren’t used nearly the maximum amount as straight through coaxial cable. Then, what’s the distinction between them? distinction between straight through and crossover cables are introduced during this post.
T568A And T568B Wiring customary Basis
A RJ45 connection could be a standard eight position, eight pin connection used for terminating Cat5e patch cable or Cat6 cable. A pinout could be a specific arrangement of wires that dictate however the connection is terminated. There are 2 standards recognized by ANSI, transient ischemic attack and EIA for wiring local area network cables. the primary is that the T568A wiring customary and therefore the second is T568B. Read more here about the T568A.
T568B has surpassed 568A and is seen because the default wiring theme for twisted combine structured cabling. If you’re unsure of that to use, opt for 568B. Some impressive knowledge of monitor cables will help you understand these much comfortably. You can refer to Zappedia Website to know more of it.
What Is Straight Through Cable?
A straight through cable could be a style of twisted combine cable that’s employed in native space networks to attach a pc to a network hub like a router. this kind of cable is additionally generally known as a patch cable and is an alternate to wireless connections wherever one or a lot of computers access a router through a wireless signal. On a straight through cable, the wired pins match. Straight through cable use one wiring customary: each ends use T568A wiring standard or both ends use T568B wiring standard. the subsequent figure shows a straight through cable of that each ends are wired because the T568B customary.
What Is Crossover Cable?
A crossover coaxial cable could be a style of coaxial cable accustomed connect computing devices along directly. in contrast to straight through cable, the RJ45 crossover cable uses 2 completely different wiring customarys: one finish uses the T568A wiring standard, and therefore the alternative finish uses the T568B wiring customary. the inner wiring of local area network crossover cables reverses the transmit and receive signals. it’s most frequently accustomed connect 2 devices of the identical type: e.g. 2 computers (via network interface controller) or two switches to every alternative.
Choose a Straight Through or Crossover Cable?
Straight through vs crossover cable, that one ought to I choose? sometimes, straight through cables are primarily used for connecting in contrast to devices. And crossover cables are use for connecting alike devices.
Use straight through coaxial cable for the subsequent cabling:
Switch to router
Switch to computer or server
Hub to computer or server
Use crossover cables for the subsequent cabling:
Switch to change
Switch to hub
Hub to hub
Router to router
Router local area network port to computer NIC
PC to PC
Straight through and crossover cables are wired otherwise from one another. One straightforward thanks to tell what you’ve got is to seem at the order of the coloured wires within the RJ45 connection. If the order of the wires is that the same on each ends, then you’ve got a straight through cable. If not, then it’s presumably a crossover cable or was wired wrong. At present, the straight through cable is way a lot of widespread than crossover cable and is wide utilized by individuals. FS.COM provides a full vary straight through Cat5e, Cat6, Cat6a and Cat7 local area network cables with several lengths and colours choices. hunt for local area network patch cables, simply return to FS.COM!


Artificial intelligence (AI) refers to the simulation of human intelligence and awareness in machines that are programmed to think, judge, respond, and mimic humans and their actions (Frakenfield, 2022). It is commonly used by people to describe any piece of technology that mimics human learning and problem solving skills.
The term is used to describe everything from finding the best route on Google Maps, self-driving cars, algorithms to display a list in a certain order on a website or in a social media app, and facial recognition software to unlock a smart phone. It is part of our everyday lives, at work, in university and at home. Developments in Artificial Intelligence (AI) have progressed at an incredible rate, and are predicted to impact many areas of society, including education in the coming years.
One such development is the emergence of generative artificial intelligence (AI). AI systems that are generative have the ability to produce text, images, or other forms of media in response to prompts. A prompt (or prompt engineering) is the command or instruction you enter into a generative AI system to create a desired output - for example, a piece of written text or an image relating to a particular topic, idea, person, and so on.
This guide will help students and staff explore a range of generative AI technologies and consider how these technologies might affect their teaching and learning practice.
The University of South Wales (USW) is committed to leveraging generative AI for the benefit of students and staff, and promotes the fair, ethical, professional, and responsible use of generative AI tools.
The University is committed to preparing our students for an increasingly AI-enabled future and acknowledges digital fluency as a key USW graduate attribute.

In this passive filter, an extruded aluminum chassis was used, with great resistance to shocks, vibrations and mechanical fatigue to which they will be subjected. The encapsulation also has another purpose other than the one mentioned above, which is to isolate the components, mainly the inductances, from external electromagnetic fields, which could negatively influence the crossover frequencies and cutoff inclinations of the different paths in the system's music reproduction. We highlight these details in relation to the widespread use of filters encapsulated in plastic chassis, with very low mechanical performance, which are also completely permeable to magnetic leakage from speaker motors. It is also worth highlighting the connection system, since as a rule, strong section cables are used from the amplifiers to the speakers. Therefore, threaded connectors were mounted to minimize contact resistance, and capable of accepting a large diameter of wire, maintaining perfect electrical contact under all circumstances. The components used are of high quality, highlighting inductances with a low saturation level at high powers, and with a strong wire section for the bass path, and electrolytic capacitors with low losses and high allowable voltage (100 V). A relatively low crossover frequency (80 Hz) was chosen so that the subwoofer would only reproduce this part of the musical spectrum, leaving the function of reproducing the rest of the higher frequencies to the lower-mid speakers. Crossover frequency 80 Hz Attenuation inclines 6dB/octave. Allowable power 200w Cont. 400w Program 4 ohm impedance.


In broadcast communications, 5G broadband is the fifth-age innovation standard for cell networks that wireless organizations started to send overall in 2019, and is the arranged replacement to the 4G organization that gives availability to latest cellphones. As indicated by the GSM Association, 5G organizations are projected to have over 1.7 billion endorsers overall by 2025.
Like their ancestors, 5G organizations are cell organizations, in which the assistance region is partitioned into more modest geographic regions called cells. All 5G remote gadgets in the cell are associated with the Internet and phone networks by radio waves through a neighborhood recieving wire in the cell. The new organization has higher download speeds, at last up to 10 gigabits each second (Gbit/s). As well as being 5G quicker than existing organizations, 5G has higher transfer speed and can consequently interface more various gadgets while working on the nature of Internet administrations in blocked regions. Because of the expanded data transfer capacity, it is normal that the organization will be progressively utilized as normal Internet specialist co-ops (ISPs) for PCs and work stations, rivaling existing ISPs like satellite Internet, and in the Internet. It will likewise make conceivable new utilizations of things (IoT) and machine-to-machine regions. Cellphones with 4G capacity alone can’t utilize the new organization, which requires a 5G-skilled remote gadget. Follow whatisss to know more about such technologies.
5G organizations are cell organizations, in which the help region is separated into more modest geographic regions called cells. All 5G remote gadgets in a cell discuss by radio waves with a cell base station by means of fixed recieving wires, on recurrence channels determined by the base station. Base stations, called GnoDBs, are exchanging focuses in phone organizations and associated with switches for Internet access by high-data transmission optical fiber or remote backhaul associations. Like other cell organizations, a cell phone moving starting with one cell then onto the next is consequently doled out to the ongoing cell. 5G can uphold 1,000,000 gadgets for each square kilometer, while 4G backings just a 10th of that limit.
The business affiliation that lays out principles for 5G, Third Generation Partnership Project (3GPP), characterizes “5G” as any framework utilizing 5G NR (5G New Radio) programming – a definition that was presented in 2018. came into general use toward the finish of The base norms are set by the International Telecommunication Union (ITU).
Many organization administrators use millimeter waves, called FR2, in 5G phrasing, for added limit and higher throughput. Millimeter waves have a more limited range than low-recurrence microwaves, so cells are restricted to a more modest size. Millimeter waves likewise experience more difficulty going through building walls. Millimeter-wave recieving wires are more modest than the bigger radio wires utilized in past cell organizations. Some are a couple of centimeters long. You should also know about What Is 5G UC.
5G paces will go from ~50 Mbit/s to 1,000 Mbit/s (1 Gbit/s). The quickest 5G paces will be in the mmWave band and can arrive at up to 4 Gbit/s with transporter accumulation and MIMO.
Sub-6 GHz 5G (mid-band 5G), by a wide margin the most well-known, will commonly convey somewhere in the range of 100 and 1,400 Mbit/s, yet will have a lot higher reach than mmWave, particularly outside. C-band (N77/N78) will be sent by different US administrators in 2022. The C-band was wanted to be sent by Verizon and AT&T toward the beginning of January 2022, yet was deferred because of safety concerns raised by the Federal Aviation Administration.
At first, the term was related with the International Telecommunication Union’s IMT-2020 norm, which required a hypothetical pinnacle download speed of 20 gigabits each second and transfer paces of 10 gigabits each second, among different necessities. Then, at that point, industry norms bunch 3GPP picked the 5G NR (New Radio) standard along with LTE as its proposition to present the IMT-2020 norm.
5G NR can incorporate low frequencies (FR1), frequencies under 6 GHz, and frequencies over 24 GHz (FR2). Notwithstanding, the speed and dormancy in early organizations of FR1 utilizing 5G NR programming on 4G equipment (non-independent) is just somewhat better compared to more up to date 4G frameworks, assessed to be 15 to half better. The standard archives for 5G are coordinated by 3GPP.
The 5G framework design is characterized in TS 23.501. Bundle conventions for versatility the executives (laying out associations and moving between base stations) and meeting the board (joining organizations and organization cuts) are portrayed in TS 24.501. Details of significant information structures are found in TS 23.003.

Ear hearing aids have been life changing for many people for a number of years now. Despite its high cost, these highly sophisticated devices can allow even those with severe hearing problems, regain their hearing to a large extent. If you are suffering from a loss of hearing, then investing in an ear hearing aid will be one of the best investments you make.
The latest technology focuses on digital hearing devices and the old analogue ones are fasting becoming a thing of the past. Digital devices have a lot of benefits that makes it a far better solution for those who can afford it. Firstly, it offers a superior sound quality and the problems of noise that analogue devices has is pretty much eliminated digitally. Since digital hearing aids are controlled by a microchip it can be programmed to suit your exact hearing levels which makes it extremely effective.
Analogue hearing aids used to be rather large and bulky things, but with digital ones its became far smaller and in many cases almost invisible. Many people felt embarrassed to walk around with an ear piece, but digital devices as far smaller.
There are essentially 4 styles of ear hearing aids on the market. Each one is slightly different in the way it works and the style that best suits you depends on your own unique situation. The behind-the-ear (BTE) hearing aid is still the most inexpensive but its also the biggest and gets fitted over the ear. Inside-the-ear (ITE) aids are those that sit just inside the ear while in-the-canal (ITC) devices sits mostly inside the ear canal and is virtually invisible with just a small part sticking out. The most advanced devices are the completely-in-the-ear-canal (CIC) hearing aids that are positioned deeper inside the ear canal and completely invisible.
Ear hearing aids can truly give you one of your most important senses back. Even people with severe hearing loss can regain a high percentage of hearing with the right device. Your hearing is important and an important part of functioning normally in society. Its important that you consult a specialist before you purchase a device as they will be able to give you the best guidance on what to buy and even if a second hand hearing aid may be viable.

Praxis features an audio engine that allows your program to synthesize audio in real time. A demonstration of this can be seen in the Synthbench program, which synthesizes audio and renders the waveforms it generates. It emulates the style of the Reactable system, where you arrange widgets on a table to generate a sound. Some widgets emit a waveform, some widgets apply an effect to the waveform they have been placed on top of and some widgets emit a low frequency waveform for controlling a parameter of the widgets it is connected to. Once again, I made this because when I saw the Reactable I thought it looked really fun, so I wanted to make a version of this “toy” for myself so I could play with it. That’s what praxis is all about – making your own universe of play where any toy you care to describe can be brought to life.
The version of Synthbench that exists in praxis only features the node audio generation behaviours and rendering. What is missing is being able to place new nodes and move them around with the mouse: you need to use code to add new nodes and move them. This is purely due to laziness. I chose to write the part of Synthbench that I wrote mainly to test that real time audio generation could be done fast enough in Lua. That is, each node needs to generate and render enough samples per second to satisfy the audio pipeline while maintaining 50 frames per second. After I was satisfied that it works, I let my attention drift to other things.

Do you have a headless Raspberry PI device and need to make minor changes? What if do not have the time to connect a monitor and a keyboard? No worries! Learning how to remotely access Raspberry PI devices will do you a favor.
In this tutorial, you will walk through the steps to install SSH and enable SSH on your Raspberry PI to remotely control your device.
Ready? Read on and start remotely controlling your Raspberry PI devices!
This tutorial comprises hands-on demonstrations of remotely accessing Raspberry PI devices. To follow along, be sure you have the following in place:
- At least one Raspberry PI device – This tutorial uses Raspberry PI 4, but the steps are applicable to all versions of Raspberry PI devices.
- A computer (Windows, Mac, or Linux) – This tutorial uses Windows 10 to access Raspberry PI remotely.
Installing SSH on a Raspberry PI Device
As you set up SSH on your Raspberry PI device, ensuring the SSH daemon is installed and running is crucial. The SSH daemon is the background process that allows you to remotely access your Raspberry PI device.
SSH daemon should be installed by default on your Raspberry PI device, but double-checking would not hurt.
1. Open a terminal in your Raspberry PI device, and run the
systemctl command below to check if the SSH daemon is installed.
sudo systemctl status sshd
If the SSH daemon is installed and running properly, you will see a message similar to the one below.
sudo apt update && sudo apt install openssh-server -y
3. Once the installation completes, run the following commands to
enable the SSH daemon (
sshd) to start automatically at system boot.
# Starts the SSH daemon
sudo systemctl start sshd
# Enables the SSH daemon to start automatically at system boot
sudo systemctl enable sshd
💡 If you are having trouble enabling the SSH daemon, jump to the following “Enabling SSH via the
4. Finally, check the status again to ensure that the SSH daemon is running properly.
sudo systemctl status sshd
sudo systemctl status sshd
Enabling SSH via the
If you have successfully enabled the SSH daemon, you are in luck. But if you got the “timeout” or “Failed to start service” error, you need an alternative.
systemctl enable command tends to lead to errors. But fortunately, an alternate method or utility for enabling SSH on your Raspberry PI device called
raspi-config exists. The utility allows you to configure and manage various settings on your device, including enabling SSH.
1. Run the below command to launch the
raspi-config utility, which will present you with a menu of options, as shown below.
Use the arrow keys on your keyboard to navigate through the menu and press Enter to select the option labeled Interfacing Options. This option lets you enable various interfaces on your Raspberry PI device, such as SSH.
2. Next, select the SSH option and press Enter, which opens a new window where you can enable SSH.
3. Now, press the Tab key to move the cursor to Yes, and press Enter to enable SSH on your Raspberry PI device.
Ignore the cautionary message that appears since You will change the default password in the following section. Press Enter twice to exit the
Changing the Default SSH Password
You have successfully enabled SSH on your Raspberry PI device, but you must still ensure your device will not become compromised. How? By changing your default SSH password.
The default password for the ‘pi’ user on Raspberry PI devices is ‘raspberry’. While the default password may be convenient, it poses a security risk.
Run the following
passwd command to initiate changing your default SSH password.
When prompted, provide the current default password, and enter and confirm a new password twice. Make sure to choose a strong, unique password to avoid getting your device getting compromised.
At this point, your Raspberry PI device is more secure. But how do you connect to your Raspberry PI device remotely? You will first need to get your Raspberry PI device’s local IP address in the following step.
Now, run the below
hostname command to get your Raspberry PI device IP address (
Take note of the IP address, as shown below, as you will use it to remotely access your device over the internet on the same network.
Connecting to the Raspberry PI Device Remotely
Now all the hard work is done, and you can finally connect to your raspberry PI device remotely. But first, you will need an SSH client.
If you are using Windows, KiTTY is a popular choice. For macOS and Linux users, the built-in terminal works fine, but this tutorial uses Kitty for demonstrations.
Open KiTTY, and configure the destination to connect to and the connection type with the following:
- Enter your Raspberry PI device’s local IP address in the Host Name field (i.e., [email protected]).
- Enter 22 for the Port number.
- Select SSH as the Connection type.
Keep other settings as is, and click Open to connect to your Raspberry PI device remotely.
Now, enter the new password you set for the ‘pi’ user in the “Changing the Default SSH Password” section.
If successful, you will be logged in to your Raspberry PI device, as shown below. And that is it! You can now manage your Raspberry PI device remotely to your heart’s content.
Remotely accessing your Raspberry PI device is a great way to get things done faster without sacrificing security. There are a few steps involved to ensure everything is set up correctly and securely. But you will surely get the hang of remotely accessing your Raspberry PI devices.
With your SSH configuration setup, enjoy all the amazing projects you can create with your Raspberry PI device!

As IT is a very vast subject area having lots of facts and information doing an assignment of IT will involve lots of information and facts. With the help of Information Technology Assignment help a student can get all the information that is needed to complete the assignment.
Computer technology that we used today is very advanced. It has evolved through many years and has developed rapidly in the recent years. Today every work is done with the computer or computer based technologies. While writing an assignment on information technology it is very important to give the important facts regarding the evolution and history of the computers. All these information can be found on the Information Technology Assignment help.
Charles Babbage who is considered as the father of the computer had proposed the first computing device in the year 1834 which was a analytical engine. However Colossus developed the first working electronic computer in the year 1940 but it was also replaced by RAM(Random Access Memory) developed by William Tube and after that lots of developments were carried out in the field of computers such as Eniac in the year 1946 which was known as the first generation computer, then came the UNIVAC in the year 1951 which was known as the second generation computer and in the year of 1980 MsDos was born and PC was introduced by IBM which was considered as the third generation computer.
Information Communication technology is also a major part of the Information Technology. Information Communication Technology is the technology in which information is accessed with the help of Telecommunication.

Wi-Fi video transmitter
This is the perfect solution for those who want to record stills and video from their night vision, thermal, or other video source without the wires. This wi-fi transmitter allows you to send the signal to your android or IOS device (up to 100 yards with clear line of sight).
This unit has been built with 5.5mm X 2.5MM barrel power plugs (Input: Female and output: male) and RCA video input. having both power input and output allows you to run the transmitter from the same external power source as your scope. The kit also includes an adapter that allows you to power the transmitter from a single 9V battery should you not have an external power source.


Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Note: you could optionally connect the alligator clips directly to the electrodes.
Power 2x 9V Battery 2x 9V battery clips. Anything around 80k should suffice. Our MyoWare sensor uses 82k resistors for example. We will make these using two 9V batteries. Now, everyone knows what a positive voltage power supply is, e. Common electrical circuit rule of thumb is when you connect two batteries in series eg positive terminal of battery 1 connected to the negative terminal of battery 2 then measure the voltage from the negative terminal of battery 1 and the positive terminal of battery 2, the measured voltage is equal to the summation of the voltages of battery 1 and battery 2.
So how do we get the -9V from these two? It might help to think about what voltage actually means… voltage is an electrical potential difference.
The keyword here is difference.
Voltages are only meaningful in terms of the reference point or more commonly referred to as ground. A voltage is the electrical potential between this reference point and the point you are measuring. Do you see the answer yet? Using your breadboard, 9V batteries and battery clips, connect the battery clip wires as shown.
DIY Muscle Sensor / EMG Circuit for a Microcontroller
However, for the time being, disconnect the positive terminal of battery 2 and the negative terminal of battery 1. It is good practice to always disconnect your power while you assemble a circuit. At the end of the assembly we will reconnect these wires to power the circuit on. You could also add switches to do this.
Next, grab two 1 M ohm resistors, bend them and then plug them in to your breadboard like the two examples shown.Electromyography EMG is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles.
An electromyograph detects the electric potential generated by muscle cells  when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order, or to analyze the biomechanics of human or animal movement. EMG testing has a variety of clinical and biomedical applications. EMG is used as a diagnostics tool for identifying neuromuscular diseasesor as a research tool for studying kinesiologyand disorders of motor control.
EMG signals are sometimes used to guide botulinum toxin or phenol injections into muscles. EMG signals are also used as a control signal for prosthetic devices such as prosthetic hands, arms and lower limbs. An acceleromyograph may be used for neuromuscular monitoring in general anesthesia with neuromuscular-blocking drugsin order to avoid postoperative residual curarization PORC. Except in the case of some purely primary myopathic conditions EMG is usually performed with another electrodiagnostic medicine test that measures the conducting function of nerves.
This is called nerve conduction studies NCS. Needle EMG and NCSs are typically indicated when there is pain in the limbs, weakness from spinal nerve compressionor concern about some other neurologic injury or disorder. Less common medical conditions include amyotrophic lateral sclerosismyasthenia gravisand muscular dystrophy. The first step before insertion of the needle electrode is skin preparation. This typically involves simply cleaning the skin with an alcohol pad.
The actual placement of the needle electrode can be difficult and depends on a number of factors, such as specific muscle selection and the size of that muscle. Proper needle EMG placement is very important for accurate representation of the muscle of interest, although EMG is more effective on superficial muscles as it is unable to bypass the action potentials of superficial muscles and detect deeper muscles.
Also, the more body fat an individual has, the weaker the EMG signal. When placing the EMG sensor, the ideal location is at the belly of the muscle: the longitudinal midline.
The belly of the muscle can also be thought of as in-between the motor point middle of the muscle and the tendonus insertion point. Cardiac pacemakers and implanted cardiac defibrillators ICDs are used increasingly in clinical practice, and no evidence exists indicating that performing routine electrodiagnostic studies on patients with these devices pose a safety hazard.
However, there are theoretical concerns that electrical impulses of nerve conduction studies NCS could be erroneously sensed by devices and result in unintended inhibition or triggering of output or reprogramming of the device.
In general, the closer the stimulation site is to the pacemaker and pacing leads, the greater the chance for inducing a voltage of sufficient amplitude to inhibit the pacemaker. Despite such concerns, no immediate or delayed adverse effects have been reported with routine NCS. Additionally, no complications from these procedures have been reported in the literature. Evoked potential testing, likewise, has not been reported to cause any problems when it is performed during pregnancy.
Patients with lymphedema or patients at risk for lymphedema are routinely cautioned to avoid percutaneous procedures in the affected extremity, namely venipuncture, to prevent development or worsening of lymphedema or cellulitis. Despite the potential risk, the evidence for such complications subsequent to venipuncture is limited. No published reports exist of cellulitis, infection, or other complications related to EMG performed in the setting of lymphedema or prior lymph node dissection.
However, given the unknown risk of cellulitis in patients with lymphedema, reasonable caution should be exercised in performing needle examinations in lymphedematous regions to avoid complications. In patients with gross edema and taut skin, skin puncture by needle electrodes may result in chronic weeping of serous fluid.Amazon Kinesis Data Firehose is the easiest way to reliably load streaming data into data lakes, data stores and analytics tools.

I actually wanted to do it without looking it up on the Internet, but now i ran into some problems.
Attached you find the Schematic of my design. The Problem is, that I just occasionally get a good reading of the muscle-contraction.
Measuring right after the INA I haven't checked the rest of the circuit so far!! Is there a flaw in my design I think thats very much the case?? Andy Watson Super Contributor Posts: You need to provide a path s for the input bias current of the INA See section 8. I totally overlooked that. If that solves the Problem I owe you a big one. Thank you very much!!!
Audioguru Super Contributor Posts: Country:. An ECG circuit is similar and uses DC coupling no input coupling capacitors from the patient, and uses shielded cables to the sensors, and the patient is biased at a DC reference of 0V with inverted common mode AC and DC signals to cancel any interference picked up. Here is a typical ECG circuit:. ECG circuit. Hi All!
Sorry for the delay! Quote from: Andy Watson on September 01,pm. You don't absolutely need a reference electrode since you are already feeding a reference voltage into your inputs via grounding your inputs through those k resistors.Zwift tron bike
The reference electrode arrangement given by Audioguru is used to feed a scaled and inverted version of the common-mode voltage from the instrumentation amplifier. This is done in order to further suppress the common-mode signal between the inputs. The common-mode interference is mains hum picked up by the ungrounded patient. There is also DC common mode interference from the patient's muscles. BTW, a lazy man's solution is to use an all-in-one chip, such as AS Expensive like hell, but has everything you need on chip -- signal conditioning, ADC, DSP and being verified by market for years.
Hi all Thanks for all your help!!!!!!!!!!!!!!!!!!! Finished the project almost a year ago Works like a treat, btw JPG There was an error while thanking.

The startup invented the underlying sensor technology that powers Myo, a gesture control armband that was initially envisioned to serve a function similar to the computer keyboard or mouse but in the VR environment. The device uses electromyography EMGa sensor technology that is typically used in the medical world to pick up electrical impulses from muscles. Lake says the product will not be a Myo 2. The product won't look like the Apple Watch or fitness trackers like Fitbitbut will instead be a completely new interface that will continue the trend towards wearables replacing phones, he said.
In many ways, the new generation of smart home devices like Amazon Alexa have already displaced the phone at home, he said. No longer if you're cooking something in your kitchen do you need to take out your phone to set a timer, when you can talk to Alexa and say 'Hey set me a timer for 10 minutes or find me a recipe for this thing I'm cooking'," said Lake.
With Myo we started with this problem of trying to solve what does the equivalent to the keyboard look like after we have all of these wearable displays and goggles in the future, and then we kind of worked backwards to say what are the technologies we have to invent to make that possible," he said.
Thalmic Labs CEO hints at what the start-up is building with money from Amazon's Alexa fund
Amazon is not known to be experimenting with wearables itself, although it is looking into health tech opportunitiesincluding hardware, CNBC recently learned. Intel, meanwhile, recently disbanded the group that focused on fitness wearables and instead is turning its attention toward augmented reality, CNBC reported.

What Happen If We Overcahrge Our Cell Phone?
Normally we have habit to charge our cell phone full night because we think that we will get 100% battery power in the morning. Now question is that, is this good habit or bad habit to over charge your smart phone? is this process damage your cell phone battery?
Is this process will decrease your battery storage capacity? We will see all this answers step by steps.
Smart Phones are really very smart. When your phone reaches to 100% then there is a system in your cell phone which stops charging automatically.
But you don’t remove your phone from charging because you are sleeping but your phone is alive so it will continuously use battery and once again it will reach to 99% then again charging will start automatically and again stop when it will reach to 100%.
This cycle will continuously repeat between 99% and 100% and it will create a problem for your smart phone. It is not 99% for all the smart phones. Few smart phones plug in again when it reaches to 90%.
It varies as per different smart phones but difference is not huge. So this process of charging and discharging will heat-up your smart phone and it will reduce the capacity of your battery.
There are some applications available on play store which can remind you when your phone becomes fully charged.

In this monograph important results that address current practical problems in Knowledge Engineering are presented. They provide solutions that are not only important, but in a number of cases they constitute a unique contribution of the author to this research domain. These important results have been presented as follows:
Chapter 3 introduces the Semantic Knowledge Engineering approach. It gives a comprehensive overview of an original knowledge representation and design methods as well as new tools proposed for the approach. In the chapter a new complete hierarchical design procedure is introduced. Based on it, a heterogeneous architecture of knowledge-based applications is proposed by the author.
Chapter 4 presents a complete formalization of the XTT rule representation language, including its syntax and semantics. The language ensures high density of knowledge representation by combining decision trees and decision tables. Contrary to traditional, flat rule bases, the representation is focused on grouping similar rules into decision components, rather than on designing single rules. It forms a transparent and hierarchical visual representation composed of the decision components linked into an inference network. In the chapter the structure of the XTT knowledge bases is described in detail. Moreover, original inference procedures for them are proposed. The chapter also contains original methods for rule verification and the detection of logical rule anomalies.
Chapter 5 contains a description of a new design, implementation and analysis environment for XTT-centric design of Rule-Based Systems. The environment supports all phases of the design process. The proposed set of tools allows for conceptual prototyping of the XTT knowledge bases, and their logical design with formalized verification and detection of logical anomalies. The implementation of systems containing an XTT-based logical core is also supported.
Chapter 6 introduces an original rule-based knowledge engineering framework for the Semantic Web. The framework contains a formal calculus for integrating the XTT rules with Description Logics, called DAAL. Moreover, it offers a hybrid reasoning engine, PELLETHEART, that is able to use rules with ontologies. The framework can be practically used with a new knowledge engineering tool LOKI which extends the semantic wiki functionality.
Chapter 7 discusses an original bi-directional translation of the XTT rule-based representation to the UML notation used in Software Engineering. The translation preserves the semantics of the XTT model. It is a valuable tool for designing applications in the heterogeneous architecture, where a logical application core is clearly identified. The primary motivation for this translation is to provide an illustrative representation of the XTT logical model. This representation uses the notation that software engineers are familiar with.
In the Semantic Knowledge Engineering approach, rule language used to build the knowledge-based model is formalized not only on the syntactic, but also on the semantic level. Moreover, the semantics of language expressions (atomic formulae) is considered, including the relations between these expressions. The semantics of the logical inference process is considered. A number of inference methods for the same knowledge base built with the language is provided. Their application depends on the needs of the user and is not determined by a single algorithm. Moreover, logical aspects of the model quality are discussed. It is possible to detect certain semantic anomalies of the model. The semantic aspects of the design process of the model are considered, and the process is precisely defined in several consecutive phases. These correspond to different levels of abstraction of the knowledge the designer has.
To summarize, the original contribution of this monograph in the fields of Computer Science and Artificial Intelligence is the following:
The presented approach has been applied in several areas as discussed in this monograph. These include knowledge management, Business Rules, Software Engineering and the Semantic Web. Moreover, other applications not discussed in the monograph include soft-real time control of mobile robots, and the design of reliable computer security systems. All of the above mentioned topics have been discussed in other papers by the author.
Based on the monograph, as well as the set of important papers, I successfully passed the habilitation procedure, and received the habilitation degree (DSc) in Computer Science, at AGH UST on 2012.05.10.

Modular design compartmentalizes critical functions for redundancy. The Solenoid and Oxygen
electronics (on the SOLO board) can measure and inject oxygen independently of the Primary
Controller handset even in case that the handset or its cable is unplugged or damaged, while the
SOLO board continues to control loop PPO2 until the diver is surfacing.
The control electronics uses the DiveCAN®, a digital communication standard developed by
Shearwater Research Inc. specifically for rebreathers for robust error-checked communications,
when a message is either received correctly or it isn’t received at all. The DiveCAN® is easily
upgradable and expandable.
PPO2 reading output from all three oxygen sensors are electronically separated one from another
as well as the PPO2 reading outputs to the Primary Controller Bus and the Secondary Monitoring
Bus are electronically separated one from another.
The Secondary Monitoring Bus is independent on the Primary Controller Bus and provides backup
PPO2 monitoring in the event of a failure on the Primary Controller.
A fault or short circuit on any sensor or one connected device, it does not affect the remaining
ppO2 readings on the working device.
The Primary Controller handset, the Head-Up Display or NERD2 are connected via the watertight
connectors rated up to 300m depth. The connectors allow flexible connection of the controller
and monitoring devices as well as easy disconnection of the devices for travel, upgrades and repair.

As AI continues to advance, it has the potential to revolutionize the marketing landscape. Marketers already rely on AI-powered tools and algorithms to analyse vast amounts of consumer data, identify patterns, and predict trends. These insights allow marketers to develop targeted campaigns and deliver personalized experiences to customers. With the continuous advancements in AI technology, marketing professionals can expect increased automation, efficiency, and enhanced customer engagement.
However, as AI becomes more integrated into marketing strategies, concerns about the future of marketing professionals have arisen. Some argue that the widespread adoption of AI could lead to the replacement of human marketers. But is this a realistic possibility?
Let’s delve deeper into the potential impact of AI on marketing professionals. While it is true that AI can automate certain tasks, such as data analysis and campaign optimization, it is unlikely to completely replace human marketers. AI is a tool that can augment and enhance the capabilities of marketing professionals, rather than rendering them obsolete.
One of the key advantages of AI in marketing is its ability to process and analyse vast amounts of data at a speed and scale that humans simply cannot match. This enables marketers to gain valuable insights into consumer behaviour, preferences, and trends, which can inform their decision-making process. AI algorithms can identify patterns and correlations in data that may not be immediately apparent to humans, allowing marketers to uncover hidden opportunities and optimize their strategies.
Moreover, AI can automate repetitive and time-consuming tasks, freeing up marketers to focus on more strategic and creative aspects of their work. For example, AI-powered chatbots can handle customer inquiries and provide personalized recommendations, allowing marketers to allocate their time and energy towards developing innovative campaigns and building meaningful relationships with customers.
Another area where AI can greatly benefit marketing professionals is in the realm of predictive analytics. By analysing historical data and using machine learning algorithms, AI can forecast future trends and consumer behaviour with a high degree of accuracy. This enables marketers to anticipate customer needs and preferences, enabling them to deliver personalized experiences and targeted campaigns that resonate with their audience.
Furthermore, AI can assist marketers in optimizing their advertising efforts. By leveraging AI algorithms, marketers can automatically test and refine their ad campaigns in real-time, ensuring that they are continuously improving their performance and maximizing their return on investment. AI can analyse various factors such as ad copy, visuals, targeting parameters, and audience response to optimize ad placements and deliver the right message to the right people at the right time.
While AI undoubtedly brings numerous benefits to the field of marketing, it is important to acknowledge that it is not a panacea. Human marketers possess unique skills and qualities that cannot be replicated by AI, such as creativity, empathy, and intuition. These human traits are essential for understanding and connecting with customers on a deeper emotional level, which is crucial for building brand loyalty and trust.
In conclusion, the future of AI in marketing holds great promise. It will undoubtedly transform the way marketing professionals work, enabling them to leverage data-driven insights, automate tasks, and deliver personalized experiences to customers. However, rather than replacing human marketers, AI will serve as a powerful tool that complements their skills and enhances their abilities. By embracing AI technology and continuously adapting to its advancements, marketing professionals can stay ahead of the curve and thrive in the ever-evolving digital landscape.
Is AI Capable of Replacing Human Marketers?
While AI undoubtedly offers valuable insights and automation capabilities, completely replacing human marketers seems unlikely. Effective marketing requires a deep understanding of human behaviour, creativity, and the ability to build relationships. These qualities are difficult to replicate with AI alone.
A key strength of human marketers lies in their ability to interpret and contextualize data. While AI algorithms can identify patterns and trends, human marketers possess the intuition to make sense of this information and make informed decisions based on it. Additionally, marketing often requires a personal touch, such as understanding cultural nuances or empathizing with customer needs. This human element cannot be easily replaced by AI.
Furthermore, human marketers bring a level of creativity that AI struggles to match. Creativity is a vital component of marketing as it allows for the development of unique and engaging campaigns. Human marketers can think outside the box, coming up with innovative ideas that resonate with target audiences. AI, on the other hand, relies on predefined algorithms and data analysis, limiting its ability to generate truly original concepts.
Another aspect where human marketers excel is in building relationships. Marketing is not just about selling a product or service; it’s about establishing connections with customers. Human marketers can engage in meaningful conversations, understand customer pain points, and provide personalized solutions. This level of empathy and emotional intelligence is challenging for AI to replicate. While AI can automate certain aspects of customer interactions, it lacks the ability to truly connect on a human level.
Moreover, marketing often involves adapting to rapidly changing trends and consumer preferences. Human marketers can quickly pivot their strategies and adapt to new market dynamics. They can identify emerging trends, analyse competitor activities, and make real-time adjustments to their campaigns. AI, while efficient in processing large amounts of data, may struggle to keep up with the ever-evolving marketing landscape.
It is important to note that AI can be a powerful tool for human marketers. It can assist in data analysis, automate repetitive tasks, and provide valuable insights that enhance decision-making. AI can help marketers optimize their strategies and improve efficiency. However, it is unlikely to completely replace human marketers, as the human touch and unique skill set, they bring to the table are irreplaceable.
The Pros and Cons of AI in the Marketing Sector
Like any technology, there are advantages and disadvantages to incorporating AI into the marketing sector. On the positive side, AI can automate repetitive tasks, freeing up marketers’ time to focus on more strategic initiatives. It can also analyse and process vast amounts of data at a speed and scale that humans simply cannot match. By harnessing the power of AI, marketers can gain deeper insights into consumer behaviour and preferences, resulting in more targeted and effective campaigns.
One of the key advantages of AI in marketing is its ability to automate repetitive tasks. For instance, AI-powered chatbots can handle customer inquiries and provide instant responses, improving customer service and satisfaction. This automation not only saves time but also allows marketers to allocate their resources more efficiently, focusing on high-level strategy and creativity.
In addition to automation, AI can also analyse and process vast amounts of data. With the ever-increasing volume of data generated by consumers, AI can quickly sift through this information to identify patterns, trends, and correlations that humans may miss. By leveraging AI algorithms, marketers can gain valuable insights into consumer behaviour, preferences, and purchasing patterns. This data-driven approach enables marketers to create more personalized and targeted campaigns, resulting in higher conversion rates and customer engagement.
However, there are also potential drawbacks to consider. One concern is the ethical implications of AI in marketing. As AI becomes more capable, there is a risk of crossing boundaries and invading consumers’ privacy. Marketers must ensure they are using AI responsibly and transparently, respecting consumers’ rights and maintaining trust.
Ensuring ethical AI practices involves implementing strict data protection measures and obtaining explicit consent from consumers for data collection and usage. Marketers need to be transparent about how AI is being used and provide clear opt-out options for consumers who may not want their data to be processed by AI algorithms. By prioritizing privacy and ethical considerations, marketers can build trust with their audience and avoid potential backlash.
Another challenge is the inherent biases that can exist in AI algorithms. AI systems learn from data, which means if the data is biased, the AI’s decisions can also be biased. This can perpetuate harmful stereotypes or discriminatory practices, leading to unfair targeting or exclusion of certain groups.
To mitigate this risk, marketers must be vigilant in ensuring the data they feed into AI systems is diverse and representative. This involves using diverse datasets that include a wide range of demographics, cultural backgrounds, and perspectives. By training AI algorithms on inclusive data, marketers can reduce the risk of biased decision-making and ensure that their campaigns are fair and inclusive.
In conclusion, AI offers numerous benefits to the marketing sector, including automation of repetitive tasks and data-driven insights. However, it is crucial for marketers to navigate the ethical implications and biases associated with AI. By adopting responsible and transparent practices, marketers can harness the power of AI while maintaining trust and fairness in their marketing efforts.
Examining the Potential of AI in Marketing
Despite the potential concerns, the future of AI in marketing holds immense promise. AI has the ability to transform marketing campaigns and drive better results. By leveraging AI technology, marketers can gain a competitive edge by understanding customer needs and preferences at a deeper level, targeting their audience with precision, and delivering personalized experiences.
AI-powered chatbots have already become a common feature of digital marketing strategies. These virtual assistants can efficiently handle customer inquiries, provide real-time support, and even make product recommendations based on individual preferences. With the ability to analyse vast amounts of customer data, AI can continuously refine and optimize marketing strategies, adapting to changing market dynamics and consumer behaviour.
It’s important to note that while AI can enhance marketing efforts, it should be seen as a tool to augment human capabilities rather than replace them. Human marketers bring a unique blend of creativity, critical thinking, and emotional intelligence to the table, which AI cannot replicate.
In conclusion, AI undoubtedly has the potential to revolutionize the marketing sector. It can automate processes, provide valuable insights, and deliver personalized experiences to customers. However, the idea of AI completely replacing human marketers is unlikely. Instead, the future likely involves a collaborative partnership between AI and marketing professionals, where AI is used to augment human capabilities and empower marketers to make data-driven decisions. As AI continues to evolve, it is crucial for marketers to stay informed, embrace the technology, and leverage its potential to drive meaningful results.

John here, Interactive Media Designer for Designing Digitally, Inc. Over the past several months, we have been developing augmented reality applications for clients. With this new and exciting technology we have been giving our clients' users a fresh new experience and a whole new way to interact with both the virtual world and the real world. I wanted to take some time out to share this amazing technology our team is working with.
Augmented reality, at a very basic level, turns the real world into a canvas in which developers can construct user experiences. It makes the world we live in a playground for virtual sights and sounds. It gives us the opportunity to deliver information and entertainment to the user with real world context. To place augmented reality into a more technical light, it allows us to take visual information and map it directly to objects within real life footage. What makes augmented reality so ground breaking is that all of this tracking happens in real time. Have you ever driven by a restaurant and wondered what time it closes? Augmented reality could look at that restaurants logo along with GPS information and display a virtual billboard over the restaurant with the information you need. It may sound like science fiction but it is already being set in motion.
Although augmented reality is still in its infancy, when you look at the grand scheme of things it can still be a valuable tool in multiple fields and at various levels. Everything from simple greeting cards to educational tools to branding and marketing tools can effectively incorporate augmented reality. The simplest examples of augmented reality are novelties and publicity gimmicks. For instance, you could send someone a birthday card. When they show the card to their computer's webcam, a 3-D birthday cake would grow out of the card. A more serious example is low cost hands on virtual training. An auto mechanic could use physical tools to work on virtual car. A surgeon could perform virtual practice surgery from his computer while still using his hands. These are all possible with technology available today, but as hardware becomes faster, smaller, and more portable, applications such as these become even more cost effective and feasible.
As the technology develops, you will see augmented reality mini apps more and more often in day to day life. Real time data will be streamed to us about everything we see, smell, hear and touch. We will be able to interact with this data in order to make more informed decisions. Heads up displays will show us detailed history on cars and homes for sale as we pass them on the streets. We at Designing Digitally, Inc. are excited to be at the forefront of this amazing emergent technology. Before you know it the virtual will become real and the real will become virtual. We hope to help blur these lines.
