  Uses of Infrared Technology Radiation One of the most common uses of infrared radiation is in heat-sensitive thermal imaging cameras.  These can be used to study human and animal body heat patterns, but more often, they are used as night-vision cameras.  These have uses in warfare, as security cameras and in nocturnal animal research. Most remote controls operate by sending pulses of infrared, spelling out codes that an electronic device will recognize.  This includes TV remotes, DVD players, projectors, etc. Infrared is often used to send signals through fiber optic cables, particularly when using standard silica fibers. Fiber optic cables are commonly used to transmit audio to sound systems and for high-speed Internet connections. Infrared is also widely used in astronomy. Taking pictures of the universe in infrared can lead to some amazing discoveries.  Astronomers can look at an area of the sky that appears empty and dark in the visual part of the electrom...

Introduction The world is racing to decarbonize power generation, transportation, and industry. While solar and wind are leading the clean energy charge, they face one major challenge — intermittency. This is where green hydrogen steps in, storing renewable energy in a clean, versatile fuel that could power everything from heavy trucks to factories. What is Green Hydrogen? Green hydrogen is produced by splitting water into hydrogen and oxygen using renewable electricity via a device called an electrolyzer. Unlike “grey hydrogen” (from natural gas) or “blue hydrogen” (from natural gas with carbon capture), green hydrogen produces zero carbon emissions. Why is it a Game Changer? 1. Long-Term Energy Storage – Stores excess solar and wind energy for months. 2. Clean Transportation Fuel – Powers fuel-cell vehicles with only water as exhaust. 3. Industrial Decarbonization – Replaces fossil fuels in steel, cement, and chemical industries. 4. Grid Balancing – Hydrogen plants act as backup gene...

  Wearables The first and most widely-known modern innovation in which electronics play a key role is wearable devices – including smart watches, glasses and rings, and even  items of clothing with inbuilt patient monitoring capabilities . And, while the development of novel biosensors to measure things like heart rate, body temperature and sleeping habits is often the focus when looking at wearables, electronics and, at times, microelectronics are also key in allowing these devices to be scaled down while still carrying out their intended function. Besides functionality, there are several other factors for manufacturers to consider when selecting the right electronic components for a wearable as well, because many of these technologies are expected to be lightweight, comfortable, discreet, energy-efficient and robust. In addition to letting people measure their own vital signs on the go, wearable devices are also  driving the uptake of telemedicine  – which has only...

 Artificial Intelligence (AI) refers to the ability of machines to mimic human-like intelligence, including learning, problem-solving, and decision-making. AI applications are diverse, ranging from virtual assistants like Siri and Alexa to fraud detection in finance, personalized recommendations in retail, and even self-driving cars.  What is AI? AI encompasses a range of technologies that enable computers to perform tasks that typically require human intelligence. This includes:  Learning: AI systems can learn from data, identify patterns, and improve their performance over time.  Reasoning: AI can analyze information, draw conclusions, and make logical deductions.  Problem-solving: AI can identify and solve complex problems, often using algorithms and models designed to mimic human cognitive processes.  Perception: AI can process and interpret sensory information, such as images, sounds, and text, to understand the world around them. 

  Wearable Tech Forward-Thinking Fashion   But wearable tech is far more than just a watch or an electrical engineering trend. It can become a life-saving device. Electrical engineers have been hard at work developing wearable pieces that prevent injury and workplace accidents. For example, Sole Power boot s are specifically designed to eliminate on-the-job injuries. The boots contain technology that monitor the wearer’s real-time location, environmental conditions, and even fatigue. All in all, these boots are meant to improve situational awareness and improve safety in the workplace. Beyond boots, smart clothing is another form of wearable technology that incorporates sensors and other electronics into fabric, trackin...

  1. Wireless Power Transfer Did you ever worry about forgetting to pack your charger when getting ready to leave on a trip? Or maybe you did forget it. This trend in electrical engineering eliminates any need for concern or inconvenience. Though still in its early stages of development and production, wireless power transfer is a promising innovation for the future of electronics. In short, wireless power transfer (WPT), also known as wireless energy transfer, is the transmission of electrical energy from a power source to a receiver without the use of interconnecting wires. WPT systems use time-varying electromagnetic fields for energy transmission. These systems ride along...

  The IBOC (In-band on-channel) is one kind of technique used to transmit the radio signals like analog and digital on the equal frequency without assigning other range. This kind of technology permits the broadcasting of digital audio without using new range allocations intended for the digital signal. This system will be well-matched with obtainable tuners because it uses the accessible AM &FM bands through connecting a digital sideband signal toward the typical analog signal. The IBOC technology uses a PAC (perceptual audio coder) for digital compression that is expanded throughout Lucent Technology. A system like USADR AM IBOC DAB includes the FEC (forward error correction), the codec, blender, modem & interleaving section.
