Questions and Answers:
What are the main features to look for in a blood pressure monitor watch?
The main features to look for in a blood pressure monitor watch include accuracy, ease of use, comfort, reliability, battery life, and connectivity to other devices. It is also important to consider the size of the watch and the display screen as well as the availability of alerts and reminders.
How does a blood pressure monitor watch work?
A blood pressure monitor watch uses sensors to measure the pressure of blood against the walls of the arteries. The watch features a cuff that is worn around the wrist or arm. When activated, the cuff inflates to compress the artery temporarily, allowing the monitor to measure systolic and diastolic blood pressure. Some blood pressure monitor watches use an optical sensor to measure blood pressure through the skin without the need for a cuff. This is called photoplethysmography (PPG) and uses light waves to detect changes in blood volume.
Can a blood pressure monitor watch diagnose high blood pressure or hypertension?
A blood pressure monitor watch can detect high blood pressure or hypertension, but it cannot diagnose the condition. Only a medical professional can diagnose and treat hypertension. It is important to use a blood pressure monitor watch as a tool for self-monitoring and to provide data for medical professionals to make informed decisions about patient care.

Solar power generation system is a device system that utilizes battery modules to convert solar energy directly into electrical energy. In the light conditions, solar cell components generate a certain electric potential, through the series and parallel connection of components to form a solar cell array, so that the array voltage reaches the requirements of the system input voltage.
The battery is charged by the charge/discharge controller to store the electric energy converted from light energy. At night, the battery pack provides input power for the inverter, which converts DC power into AC power and delivers it to the power distribution cabinet, where it is switched to supply power. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery.


The Gavita EL1 Gen 2 Master Controller is an entry-level way to centrally control large rooms with e-series fixtures. This second-generation Master Controller features improved and expanded functionality that raises the bar including non-volatile memory, event logging, and independent sunrise, and sunset settings.
The EL1 has one lighting control channel and can control 500 max repeater BUS fixtures and 40 max single BUS fixtures without a booster.
Switch, Dim & Boost Centrally Now you have complete control over the light cycle and the output of your fixtures from one single point. Never reach to a ballast again!
Simple Programming Setting up the controller is a breeze, with a 5 language text interface in plain language on a high-quality OLED display.
Separate Sunrise/Sunset Set different times for sunrise and sunset.
Crop Safety - Auto-dim In extreme conditions the Master Controller automatically dims your lights, so your plants will survive the high heat.
Memory Nonvolatile memory to store user settings.
Independent Light Cycles on EL2 Models Allow to program two different, and overlapping cycles, for example, a 12/12 on channel 1 and an 18/6 on channel 2.
Logging The logging functionality provides insight into the current and past status of your lights and alarms. Logging functions for high/low temperature, last auto-dim event, last shutdown event, and last power loss.
Easy Installation The complete installation is plug-and-play. Every e-series fixture comes with all necessary cables to install it on the e-series control BUS.
Crop Protection - Auto-Shutdown When cooling or ventilation fails, the Master Controller automatically switches off your lights, preventing imminent damage to your crop (or worse).
Safe The most important and valued features of the Master controller are the temperature safety features. Your lamps will automatically dim when your climate control is no longer able to maintain the correct temperature. Or will even shut down your lamps when a maximum temperature is reached.
The control signal is a safe, analog, and low voltage signal, and the controller is protected from signal shortcuts in the wiring. Wiring faults will not kill your controller.
Flexible Whether you control two fixtures or 1,000, the Master Controller will do the job. Standard, each output channel can control 40 fixtures (Single BUS e-series) up to 500 fixtures (Repeater BUS e-series), without the addition of booster modules.

12Ghosts - 12-Z - Tjunction
To change Tjunction, right-click on the entry and select Change Tj.
Tjunction (sometimes called Tj or TCC) is the temperatur where the CPU starts to throttle down the speed, or a system shutdown is initiated. (Note, this is not the temperature specified as maximum case temperature which is somewhere between 60°C and 70°C, and also referred to as "Tcase" or "Tmax", the temperature where "maximum" cooling should be supplied.)
Usually this is assumed to be 100°C (212°F). On certain notebook processors it might be 85°C (185°F). However, neiter Intel nor AMD have ever made an official statement or published any specification. Building the temperature diode on the die is not what's difficult, but calibration still requires human intervention, which makes it expensive. Tj is different on different processors, and might even be different on two CPUs of the same processor type.
However, since we are human beings and used to deal with temperatures, it is easier to think of the maximum allowed temperature as something near the boiling point.
Tip: To verify the temperature start 12-Z, and reset Min/Max temperatures, before sending the computer to sleep overnight. After waking the computer, the minimum temperature should be just a few degrees (4°-5°C or 6°-8°F) above room temperature.

Turlock Electronics Recycling
Many people are not aware that it is not only dangerous, but also illegal, to dump electronic waste into landfills. Simply tossing that old cell phone in the trash may not seem like such a big deal, but the cumulative impact of millions of Americans improperly disposing of their consumer electronics means a swelling of toxins in landfills around the country. For instance, your average 17-inch monitor contains as much as two pounds of lead, a substance that can contaminate water and is particularly dangerous to young children.
Iron, copper, aluminum, plastic, glass, and other valuable materials can be profitably recovered from old electronic devices, including TVs, stereos, cell phones, regular telephones, computer monitors, laptops, hard drives, servers, and peripheral devices such as printers and fax machines. These metals and other materials can be recycled and used in the manufacturing of new equipment, which reduces the electronics industry’s environmental impact.
Recycling electronics in Stanislaus County has never been easier. In Turlock, a number of retailers have started recycling ewaste, taking back products such as household batteries, TVs, and cell phones.

The Wii U was a home video game console developed by Nintendo as the successor to the Nintendo Wii. The console was released in November 2012 and was considered to be part of the eighth generation of video game consoles along with Sony's PlayStation 4 and Microsoft's Xbox One. The Wii U was the first Nintendo console with HD graphics. The system's primary controller is the Wii U GamePad, which features an embedded touchscreen. The Wii U was succeeded by the Nintendo Switch in 2017.
Despite being a fairly recent console, emulators are available that even allow you to play Wii U games at reasonable fps provided you have a decent gaming PC.

UNMANNED Systems Technology magazine, Dossier: BMPower fuel cell system03.12.2018, 07:04
Ian Bamsey investigates the development of an affordable fuel cell power system that can significantly extend the flight time of an electrically powered UAV
The great challenge with multi-rotor UAVs is range. Conventionally powered by lithium batteries, in professional applications they struggle to achieve more than 30 minutes’ flying time between recharges – even with a payload of a lightweight camera. That has prompted a number of companies to look to alternative means of powering a UAV’s electric rotors.
There is no easy answer to this problem of range extension, but one that promises a major improvement is the use of a hydrogen-powered fuel cell. BMPower is showing that it can offer a practical fuel cell power system (FCPS) at a far more affordable price than the aerospace technology currently under evaluation in the military sphere. Its solution offers a threefold or more improvement in flight duration according to the specific application...

Renowned as China's cradle for the national electronic industry, University of Electronic Science and Technology of China (formerly Chengdu Institute of Radio Engineering) is situated at Chengdu, the city of over a thousand-year-old cultural history in "the land of abundance". In 1956, instructed by Premier Zhou Enlai, UESTC was founded on the basis of the incorporation of electronic divisions of the then three universities including Jiaotong Universities, Nanjing Institute of Technology and South China Institute of Technology. As one of the seven earliest key universities in national defense, UESTC became one of the nation's key universities in 1960. Then, in 1997 it was included as one of the first universities into "Project 211", a project in China for developing 100 first-class universities and a number of key fields of research for the 21st century. In 2001, UESTC was admitted into the nation's Project 985, receiving special support for developing world-class universities and world-famous research-oriented universities.
Fifty years'efforts and cultivations have witnessed the University's process from sole dependence on electronic information engineering to all-around programs in electronic disciplines, and the University now turns out to be a key multidisciplinary university with electronic science and technology as its nucleus, engineering as its major field and featured the harmonious integration of science, engineering, management and liberal arts, well prepared at the call of the history to come up as a high-level research-oriented university.
In the new century, electronic information science and technology as the lead for modern high-tech development demonstrates a more swift and violent stance. In face of the new chances and challenges, the staff of the University will hold on its notion of "great buildings and master scholars, ambition and accomplishments" in the pursuit of excellence and embark on the journey to a more glorious future.


Professor Seager's Exoplanet Space Mission Research
Professor Seager aims to find Earth-like worlds. Space telescopes above the blurring effect of Earth's atmosphere give us our best capability to fin small rocky worlds. Professor Seager is involved in several space-based missions including as PI of ASTERIA (formerly ExoplanetSat), as Deputy Science Director of TESS, and as a scienficir leader of the Starshade project.
Professor Seager's research group also works and has worked with data from several space telescopes including Kepler, Spitzer, Hubble, and EPOXI. Above the blurring effects of Earth's atmosphere, space telescopes provide excellent observations of exoplanets and their host stars.
ASTERIA: Arcsecond Space Telescope Enabling Research in Astrophysics
Professor Seager's 6U CubeSat
ASTERIA is being implemented at JPL. ASTERIA, formerly called
ExoplanetSat, is motivated by the thought that no current mission has
the capability to survey the nearest sun-like stars for an Earth
analog. The best way to monitor the brightest sun-like stars (0 < V
< 6) for long-duration transiting exoplanets is by a targeted star
search; the brightest stars are too widely separated across the sky
for a single telescope to continuously monitor. A fleet of dozens of
identical ASTERIA spacecraft would be ideal to each monitor one star
at a time, instead of a single space telescope surveying thousands of
stars simultaneously. The detailed properties of each target star are
well known in advance.
ASTERIA is a prototype nanosatellite capable of monitoring a
single, bright, sun-like star. ASTERIA will have the precision
pointing control (8 arcsecond (three sigma) ) and precision thermal
stability (ten milli Kelvin) to reach high photometric precision. To
take advantage of CubeSat launch opportunities,
ASTERIA as a 6U CubeSat (roughly 10 x 20 x 30 cm, 12 kg) that will
operate in low-Earth orbit.
The ASTERIA project is a JPL-MIT collaboration. While the concept
was conceived of and brought through TRL 5 at MIT and Draper Lab, the
program is now funded at JPL through the Phaeton Program for training
early career employees. JPL is responsible for overall project
management, systems engineering, attitude determination and control,
flight software, spacecraft implementation, integration and test, and
mission operations. MIT will lead science operations. Flight hardware
delivery is scheduled for March 2017, with launch and deployment
targeted for summer 2017.

TESS: Transiting Exoplanet Survey Satellite
The MIT-led NASA Mission TESS
is an all-sky survey for transiting exoplanets.
TESS will carry four identical specialized wide-field
CCD cameras, each covering 24 x 24 degress on the sky with a 100-mm
aperture. In a two-year all-sky survey of the solar neighborhood, TESS
will cover 400 times as much sky as Kepler did. In the process, TESS
will examine more than 0.5 million bright nearby stars and likely find
thousands of exoplanets with orbital periods (i.e., years) up to about
50 days. TESS will not be able to detect true Earth analogs (that is,
Earth-sized exoplanets in 365 day orbits about Sun-like stars), but it
will be capable of finding Earth-sized and super Earth-sized
exoplanets (defined as planets up to 1.75 times Earth's size) transiting M
stars, stars that are significantly smaller, cooler, and more common
than our Sun. The TESS search for habitable planets that may be
followed up for signs of life is, therefore, focused on M dwarf host
JWST: James Webb Space Telescope
The James Webb Space Telescope
is a 6.5 m effective diameter aperture infrared telescope, with a
launch scheduled for October 2018 on an Ariane 5 rocket from French
Guiana. JWST will be the premier space-telescope observatory of the
next decade, serving thousands of astronomers worldwide. It will study
every phase in the history of our Universe, ranging from the first
luminous glows after the Big Bang, to the formation of solar systems
capable of supporting life on planets like Earth, to the evolution of
our own Solar System. JWST is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center is managing the development effort. The main industrial partner is Northrop Grumman; the Space Telescope Science Institute will operate JWST after launch.
Professor Seager, and indeed most of the exoplanet atmosphere research community, is counting on the JWST for exquisite atmosphere observations of all kinds of transiting exoplanets. Of prime interest are the rocky worlds with thin atmospheres, transiting and in the habitable zones of "bright enough" M dwarf stars.

is a carefully shaped screen with its own spacecraft, which,
when flown in formation with a space
telescope along the line of sight to a star, blocks enough of the
light from the star to reveal any orbiting planets. The starshade size
and shape, and the starshade-telescope separation, are chosen to
control diffraction around the screen and create a very deep and dark
shadow; the planet light is unaffected due to its angular separation
from the star. Creating shadows large enough for future space
telescopes and deep enough to image Earthlike planets requires
starshades that are tens of meters in diameter and separated from the
telescope by tens of thousands of kilometers.
Use of a starshade to suppress starlight has several key strengths for
discovering and characterizing nearby Earth analogs. First and
foremost, because starlight is blocked before entering the telescope,
no complicated optics are required, resulting in high throughput and
allowing the use of any relatively small commercially available space
telescope. This is in contrast to the lower throughput observatory and
extremely specialized and difficult wavefront sensing and control
system required for the internal coronagraph technique. Second, the
inner working angle (iwa) of the starshade/telescope combination (the
smallest angle on the sky at which an orbiting companion can be
detected) is independent of telescope aperture. Rather, it is
determined by the starshade size and separation from the telescope.
Similarly, a starshade based observing system has no limiting outer
working angle; the field of view is only limited by detector size.
A starshade-based starlight suppression system is, of course, not without its own challenges. The starshade must be manufactured to the required shape while meeting precise tolerances, the petal edges must be carefully designed to be small enough to minimize sunlight scatter into the telescope, the starshade must be deployed while meeting tight positioning requirements, the starshade must be precisely positioned and pointed during observation, and the basic optical response must be understood and proven. Nevertheless, while many of these challenges are new, the starshade structure has heritage from large radio antenna deployables and the JWST sunshield; and the fundamental engineering behind the structure and deployment is well understood.
Starshade at Northrop Grumman Corporation
Ongoing and Past Missions
NASA's Kepler Space Telescope
completed its prime mission and is living on as the
K2 Mission. During its prime mission, Kepler is
monitoring 150,000 stars for nearly four years to
search for a characteristic drop in brightness
indicative of an Earth-sized planet. A huge amount of
followup work confirmed and validated a large fraction of transit light curves as consistent with a planets.
Kepler will provided statistical frequency of different kinds of
planets orbityg different star types. Kepler fell short of its main mission goal of determining the frequency
of Earth-size planets in Earth-like orbits about
sun-like stars, and the exoplanet community continues to debate a value extrapolated from larger and shorter-period planets than the true Earth analog.
Professor Seager was a participating scientist member of the Kepler team and her group analzed Kepler data of Jupiter-size and Neptune-size planets, focusing on their radii, albedo constraints from secondary eclipse, statistical properties, and any possible interpretation of physical characteristics.

Hubble Space Telescope
NASA's Hubble and Spitzer Space Telescope
provide observations of transiting planets,
planets that go in front of and behind their star
as seen from Earth. Observations of transiting
planets exploit separation of photons in time,
rather than in space. That is, observations are
made in the combined light of the planet-star
system. Primary and secondary eclipses enable
high-contrast measurements because the precise
on/off nature of the transit and secondary eclipse
events provide an intrinsic calibration reference.
This is one reason why the Hubble Space Telescope
and the Spitzer Space Telescope have been so
successful in measuring high-contrast transit
signals that were not considered in their

NASA's EPOXI is a 30 cm telescope now orbiting the sun millions of miles from Earth. EPOXI is a combination of the names for a space mission's two components: the Extrasolar Planet Observations and Characterization (EPOCh), and the flyby of comet Hartley 2, called the Deep Impact Extended Investigation (DIXI). Professor Seager was a member of a team that used EPOXI to study stars with transiting planets and also to observe Earth from afar. Professor Seager's group is trying to understand what we would learn about Earth as an exoplanet from EPOXI's near infrared spectra of Earth. For a slightly different topic of inversion of EPOXI's Earth orbital light curves to determine Earth's physical characteristics, see the following paper by an EPOXI team member:

ChatGPT, or Generative Pre-trained Transformer, is a cutting-edge artificial intelligence (AI) technology that is revolutionizing the way we interact with machines. Developed by OpenAI, Chat GPT is a powerful language model that can understand and respond to natural language inputs with unprecedented accuracy and fluency.
What is ChatGPT?
ChatGPT is a deep learning model that is trained on a massive amount of text data, allowing it to understand and generate human-like language. It uses a transformer architecture, which is a type of neural network that is particularly well-suited for processing sequential data like text.
How does ChatGPT work?
ChatGPT is pre-trained on a massive amount of text data, which allows it to understand the nuances and complexities of human language. When a user inputs a natural language query or statement, Chat GPT uses its pre-trained knowledge to generate a response or complete the statement.
One of the key strengths of ChatGPT is its ability to generate highly fluent and contextually appropriate responses. For example, if a user inputs the statement, “I’m feeling sick,” ChatGPT can generate a response such as, “I’m sorry to hear that. What are your symptoms?”
Uses of Chat GPT:
ChatGPT has a wide range of potential uses, including:
- Virtual assistants: ChatGPT can be used to create virtual assistants that can understand and respond to natural language inputs. This could be used to create more advanced and human-like virtual assistants for customer service, personal assistance, and more.
- Language translation: ChatGPT can be used to generate highly accurate translations of text from one language to another.
- Text completion: ChatGPT can be used to complete sentences or paragraphs in a way that is contextually appropriate and fluent.
- Content generation: ChatGPT can be used to generate new text content, such as articles, blog posts, or product descriptions.
Limitations of Chat GPT:
Despite its many strengths, ChatGPT does have some limitations, including:
- Lack of common sense: While ChatGPT is highly proficient at understanding and generating human language, it lacks the common sense and “world knowledge” that a human possesses.
- Bias: As ChatGPT is trained on a massive amount of text data, it can inadvertently learn and replicate biases present in the data.
- Safety: Some researchers have raised concerns about the safety of AI language models like ChatGPT, as they could potentially be used to generate misleading or malicious content.
Chat GPT is a powerful and versatile AI technology that is capable of understanding and generating human language with unprecedented accuracy and fluency. With a wide range of potential uses, from virtual assistants to language translation, Chat GPT has the potential to revolutionize the way we interact with machines. However, it is important to be aware of the limitations of this technology and to take steps to mitigate any potential risks.


Semiconductor market: AI boom boosted prices but units sold collapsedThe AI boom has had important implications for the semiconductor market. In particular the logic chips are in high demand. In 2023 surging demand was constrained by shrinking supply. This resulted in a substantial fall in units sold whereas prices surged. Here we analyze the underlying economic and technological drivers and forecast the development of global sales of the semiconductor market until the end of 2025.

I have not posted quite so much of late because I have had problems with my computer. My old HP inkjet printer finally died after a new version of Windows 10 was installed. So I ordered a reasonably priced color laser printer and immediately ran into problems.
There are so many ways to connect the printer to the computer that I was nonplussed. I tried first to connect it via USB to the computer. That didn’t seem to work, plus the USB plug didn’t sit firmly enough at the rear of the printer. Then, with the help of my friend Mike Estrin of Network Connections LLC, I tried connecting the printer to the router using Lexmark’s software.
Finally, I bought a network cable and with Mike’s help, hooked the printer to the router using it.using it. Now it finally seems to work without losing the connection or shutting down for no apparent reason.
My fingers are still crossed. My Lexmark has been functioning normally for the last twenty-four hours. I hope it continues to. The printer does produce nice copies, has good color, and is probably cheaper to run than an inkjet with a voracious appetite for expensive ink.

In 2015, the UK Government launched a rollout scheme of smart meters into every household in the UK. This was part of a £11 billion carbon emission reduction initiative which aims to reduce nationwide carbon emissions by 34%. As a result, every household in the UK will receive a smart meter by 2020, if the scheme goes according to plan.
What is a Smart Meter?
Smart meters are gradually replacing old gas and electricity meters. They work wirelessly, automatically sending energy usage details to your energy provider. Consequently, the provider uses the information to bill you based on exactly how much gas and electricity you have consumed.
What are the Benefits of Smart Meters?
Installing a smart meter in your home can provide a number of fantastic benefits. These include:
- A smart meter display allows householders to monitor their gas and electricity usage. In addition, they show how much the bill is adding up to with live costs direct from the energy supplier. The suppliers can remotely adjust tariffs based on contracts.
- Estimated readings become a thing of the past so charges are accurate.
- No need for energy providers to send out workmen to your household to gather a meter reading.
- According to the government, switching energy suppliers will also be easy work with a smart meter. The switch can go ahead faster and with minimal fuss.
- Pre-payment customers are provided with extra topping up options. Therefore the chance of running out of credit at an inconvenient time is eliminated.
- Householders can set up their smart meters to work with renewable energy sources. This will monitor how much energy the sources are providing.
- Smart meters are provided free of charge by energy providers so it’s a no-brainer.

Carbon 14 dating machine
Therefore, communication between PRL and LAMS is fast and effective.Organisation of Laboratory is an effect of cooperation of the Adam Mickiewicz University, Institute of Archaeology and Ethnology, Polish Academy of Sciences, and Centre for Archaeological Research, Foundation of the A. Poznan Radiocarbon Laboratory is the first such institution in the Central-Eastern Europe.Performance of the Poznan Radiocarbon Laboratory (PRL) is possible due to a close collaboration with the AMS Laboratory (LAMS), housed at the same floor, and leaded by the same person.Carbon dating is an essential tool of modern archaeology because it allows the age of a biological sample to be determined from the radioactivity of its carbon compounds.
However, for samples aged around 50,000 years or older, accelerator mass spectrometry (AMS) is the only method that is sensitive enough to detect the minute amounts of remaining carbon-14.
Mickiewicz University in Poznan The Laboratory is kept by the Foundation of the A.
Mickiewicz University and is housed in the area of the Poznan Park of Science and Technology C laboratories are usually open to cooperate with wide community.
For carbon dating, the process starts in an ionizing chamber, where the atoms within a sample of pure carbon are given a negative charge.
An accelerator then increases the kinetic energy of the carbon ions to 10-30 million electron volts and moves them through a tube where a powerful electromagnet makes them change direction. Because carbon-14 decays over time, the amount of it in a sample indicates the age of the sample.


What is Artificial General Intelligence?
There are three levels of Artificial Intelligence. What is Artificial General Intelligence, you might then ask? The answer is that its level of artificial intelligence that matches human intelligence. So anything that a human can do, AI can do to. This article outlines the consequences of reaching that state of AI.
The level at which AI‘s intelligence and human intelligence are at an equal level is called Artificial General Intelligence (AGI). Machines at this stage have at the same intellectual capacity level as we as humans have.

Equivalence Checking of Digital Circuits by , Book Resume:
Hardware veri?cation is the process of checking whether a design conforms to its speci?cations of functionality and timing. In today’s design processes it becomes more and more important. Very large scale integrated (VLSI) circuits and the resulting digital systems have conquered a place in almost all areas of our life, even in security sensitive applications. Complex digital systems control airplanes, have been used in banks and on intensive-care units. Hence, the demand for error-free designs is more important than ever. In addition, economic reasons underline this demand as well. The design and production process of present day VLSI-circuits is highly time- and cost-intensive. Mo- over, it is nearly impossible to repair integrated circuits. Thus, it is desirable to detect design errors early in the design process and not just after producing the prototype chip. All these facts are re?ected by developing and prod- tion statistics of present day companies. For example, In?neon Technologies  assumed that about 60% to 80% of the overall design time was spent for veri?cation in 2000. Other sources cite the 3-to-1 head count ratio between veri?cation engineers and logic designers. This shows that verifying logical correctness of the design of hardware systems is a major gate to the problem of time-to-market (cf. ). With the chip complexity constantly increasing, the dif?culty as well as the - portance of functional veri?cation of new product designs has been increased. It is not only more important to get error-free designs.

Easy Ways to Fix Nighthawk Extender Not Found Issue
Installing Nighthawk WiFi range extenders to fulfill internet requirements has become one of the most common practices these days. After users setup Netgear Nighthawk extender, they need to connect to the WiFi network to enjoy the internet. FYI, Netgear_ext is the network name of the WiFi extender. But, what if this WiFi name does not show up on the WiFi list? Yes, we are talking about the Nighthawk extender not found issue. In this case, accessing the internet on wireless client devices seems impossible sometimes. But, every problem has a solution. With that said, let’s start our post focused on troubleshooting the issue when a WiFi extender is not found on network lists of client devices (mobile phones, tablets, laptops) present in its range. You can take the help of the information provided here if you are struggling with the same problem.
Overview: Nighthawk Extender Not Found
You might have got complete idea about the issue we’re going to tackle here. But, don’t you think that the picture will become clearer if you are familiar with the reasons behind the issue? Right from an outdated firmware of the extender to WiFi interference present in the path of communication of your devices, many reasons work together to create this annoying issue. But, the most common one is a disturbance by a network glitch. To do away with that you are supposed to power cycle the entire home network. For this, first of all, power down the modem, then your router, and lastly the extender. You can also unplug these devices from the power socket. After that, consider waiting for 10-30 minutes. Once done, power up all your devices in the same sequence as you powered them off. In case the Nighthawk extender not found issue is still adamant about leaving you, then it is recommended that you take the assistance of the tips highlighted in the next section.
Solutions: Netgear WiFi Extender Not Found
|1||Outdated firmware of WiFi extender||Connect your computer to the extender directly i.e. using a LAN cable and upgrade the firmware by accessing the Netgear Genie setup wizard|
|2||WiFi signal interference||Remove the physical obstructions present in the path of communication between your Netgear Nighthawk WiFi range extender and the client device.|
|3||Poor internet service||In this case, you must check the LAN cable connection between the extender and router. If everything is fine, contact your ISP to inquire about internet-related issues.|
So, these were the easy solutions corresponding to the reason causing the issue. It is expected that you will now be able to resolve the problem using these solutions. But, if you are still unable to see the WiFi extender network name on the list, then there is a possibility that you disabled the SSID broadcast during the setup process. Therefore, consider checking if what we’ve just stated is true or not. You can do so by following the instructions highlighted in the next section.
How to Check If Extender is Broadcasting SSID?
We are assuming that your WiFi range extender is powered up and you’ve successfully connected it to the main router through a LAN cable. Know that you’ll need an additional cable to connect your computer to the extender since you won’t be able to see the extender’s SSID on the network list. After that, follow the steps given below:
- Switch on your computer and launch an internet browser.
- You must visit mywifiext.net now.
- When prompted to log in, use the valid extender credentials.
- On the Netgear Genie dashboard, go to WiFi Settings.
- Now, see if Enable 2.4GHZ WiFi or Enable 5GHz WiFi and Broadcast this Network Name (SSID) boxes are checked.
- If not, then check them and save the settings.
In older extender models, you need to follow the path: Advance > WiFi Settings > Check Wireless Access Point and Enable SSID Broadcast to fix the problem.
The Concluding Thought
With that, we are now wrapping up the post that aimed to fix the Nighthawk extender not found issue. We are hoping that you will be able to see the extender’s network name after enabling the SSID broadcast. However, if you do not want to enable the SSID broadcast, then you are supposed to manually enter the SSID of your extender in the network list of your client device to use the internet.


Illusions in the Round
The technology of the future could be controlled by light.
n the future gamers will be able to engage with hologram hordes not just on flatscreens, but in 3D – as soon as light-based computers become available. These machines will process data 100,000 times faster than today’s models. Physicists are actively seeking ways to overcome the technical obstacles that currently stand in the way of optoelectronic computing. A possible solution to the problem of heat dissipation has now been demonstrated.
The year is 2050, and we’re in a huge hangar in an industrial area on the edge of a megalopolis. The raucous sounds of a life-and-death struggle echo in the surrounding streets. In the hall itself, a host of merciless orcs mounts an apparently unstoppable onslaught against the small group of plucky comrades, who have assembled here this evening for an exciting adventure in the world of virtual reality. Though hopelessly outnumbered, the tiny fellowship repeatedly repulses the attacks launched by the onrushing battalions of the creatures of darkness. Above the tumult of the battlefield there is tumult in the sky. Against the backdrop of lowering stormclouds, pale lightning flashes erratically illuminate the scene, and thunderclaps compete with the already deafening sounds of clashing weaponry. One by one, the orcs succumb, and the holograms dissolve into nothingness. The doughty defenders have held the own, and won the day. – Then the lights go up, and the exhausted warriors troop off to the bar to quench their thirst and raise a toast to a famous victory.
The creation of virtual worlds, such as one in which hologram armies seek to conquer a hologram landscape, requires enormous reserves of processing power, and the processing must be done at mind-boggling speed. For, of course, a lumbering orc whose reactions are slow is no match for a nimble opponent. In spite of rapid progress, currently feasible rates of data transmission and processing are not high enough for game engines to be able to simulate virtual worlds in three dimensions on a large scale. But that is set to change. Future computers will have the capacity to operate as fast as visible light waves oscillate, enabling them to process data at speeds 100,000 times higher than those attainable today.
Light waves oscillate with frequencies on the order of one trillion (1012) times per second, as do and their associated electric fields. And these electric fields influence the behavior of the electrons that serve as the carriers of data and information in our digital computers. Thus light-based computers could perform one trillion elemental switching operations every second.
It will, however, take a while before we can expect to see the first optoelectronic data processing machines on sale. But the basis for this transformative technology has already been established. For instance, it is now possible to direct the motions of electrons at optical frequencies. – Then there is the problem of heat. Computer operations generate heat, and computers must at all costs be protected from overheating. The light-driven electronics of the future will also have to deal with this problem. The challenge here is to find a solid that supports the necessary interactions between light and matter, but is capable of rapidly re-emitting the light energy transferred to its electrons in the process. Silica (SiO2) – in other words, glass – is one promising possibility. Indeed, recent experiments have shown that the electrons in glass respond to the ultrashort light pulses as expected, but the amount of energy irreversibly absorbed is vanishingly small, while the rest is quickly dissipated. As a result, the glass does not heat when trains of light pulses are directed onto it in rapid succession over long periods. This discovery is so significant and spectacular that the researchers reported their findings in the leading scientific journal Nature.
So this quite literally ‘cool’ relationship between light and glass could provide a solution to the question of how electronic data processing can be accomplished at optical frequencies without running the risk that the computer will overheat. Optoelectronics would then have reached the maximal attainable rate of data transmission and data processing. Hence light-based computing at optimized optical switching rates could open up entirely new opportunities for data-intensive simulations, in fields such as climate modelling, forecasting of natural disasters or virtual tests of the action of new drugs in real organisms. In terms of possible applications for optoelectronics, the sky’s the limit.
Of course, none of this implies that close encounters with virtual orcs in the year 2050 will be a picnic. But at least their intrepid opponents will not have to do battle at torrid tropical temperatures because the optical computers needed to conjure up the holograms radiate so much heat!


360 Degree Rotating Led Motion Sensor/ Torch Light
3 Different Mode:
Auto Mode: Motion Sensor Light
The light will automatically be switch on when motion is sensed within a distance of not more than 10 meter away from the sensor which is the protruding ball on the lamp.
In order to save the electricity or battery life, the sensor light can only be switched on when the area is dark. Thus in bright area, the light will not be activated.
Sensor light is a device that every house should be. It can be place near the doorway as a method to prevent theft. The moment motion is sense when coming in to the doorway, the light will automatically be switched on. This will alert the theft and prevent further crime from happening.
Sensor light can be used to improve visibility of the room when the area is is too dark to be visible. The light will be auto switch on before you can find and switch on general lighting.
The light is set at a mode that it will auto shut off the light after 30 second in auto mode.
On Mode: Torch Light / Table Lamp
Small and compact in size. It can be easily carried or moved around. A torch light is needed in every household. It can also be used as a table lamp. Led light which is cooler in temperature and brighter than other kind of lighting. 360 degree rotating device meaning it can be position to the preferred direction by rotating the torch.

Science, Technology, Engineering and Manufacturing (STEM) based subjects cover a whole array of different topics covering the land, air and sea. The continuous development and innovation in STEM based subjects will improve the quality of life, extend our existance in the world and help us explore the abyss of space - time.
The energy sector will continuously thrive on innovative technology to make energy generation more environmentally friendly, next generation manufacturing techniques to reduce power station production costs, scientific knowledge to develop fusion and engineering to put theory into practice.
The founders of Great Western Energy have been educated in STEM based subjects and therefore have an inherent obligation to educate the next generation. This is not just a a recruitment excercise for the STEM subjects, but an excercise to engage with people who don't have a passion in STEM subjects with the hope of spreading the word of the great things that happen in these subjects. Afterall, we could be talking with the generation of politicians, entrepreneurs or business leaders, but more importantly the next generation of mums and dads.
This very equation describes the meaning of energy, which is part of our name and industry. It was derived by Albert Einstein, and is not just a description of the energy sector, but also part of the founding principles of the universe we occupy.
Innovative developments are becoming more challenging day-by-day as new technology is produced, managed and developed. The first car was produced in 1807 powered by the internal combustion engine and since modern technology has managed to introduce new propulsion methods, aerodynamic concepts and crash technology. The point is, technological developments happen at rocket car pace!
There are many demands that the energy sector is going to have to meet over the coming years that have been enforced by environmental legislation, fossil fuel depletion and energy generation costs. These challenges will be tackled in two parts, long-term and short-term. The solutions include:
Smart technology will help raise awareness in the way we consume energy, increased insulation in our homes and energy efficient technology such as LED light bulbs. More emphasis has been placed into reducing energy consumption in the work place with government levys, taxes and incentives.
Renewable energy generation can exist in many forms including nuclear, hydroelectric, photovoltaics, wind and wave. The most efficient form of energy generation is hydroelectric, where the conversion of gravitational potential energy to electrical energy is approximately 80% and photovoltaics usually are the least efficient at or below 20%. The biggest issue with renewable energy generation is the cost per kWh is much higher than fossil fuel power stations.
We are open to visiting local community organisations to educate society on the modern challenges faced in the energy sector and STEM based industries. We can use our wide range of skills to talk on STEM in addition to entrepreneurship and business management.
If you are interested in one of us holding a talk, or even mentoring a student, please contact us through the "Get In Touch" page.
