From the small vibrating motors in cell phones to the more complex motors used in household washing machines and air conditioners, motors have become everyday fixtures in the consumer world. The energy consumed by all these motors is significant...
Field effect transistors (FETs) are important semiconductor devices because they are fundamental components of many devices and electronic instruments. Some of the countless applications for FETs include their use as amplifiers, memory devices, switches, logic devices, and sensors.
The advent of wireless connectivity in the home automation market has enabled developers to create many innovative products that make end users feel safer and more aware of their personal property. Remote tamper detection is one example of innovation made possible through wireless connectivity.
Forming a beam or multiple beams with an electronically scanned array antenna has found utility in a number of applications. These include radar, communication systems, radio astronomy and others. An array antenna consists of multiple antennas or radiating elements that each transmits a signal....
It’s hard to believe some 20 years after Internet became available to most Americans that many of our neighbors are still not only offline but computer illiterate as well. I was reminded of that fact in March when the Governor of New Jersey proposed that the unemployed in the state, as a condition to receive their benefits, use the state’s jobs listing web site each week.
Choosing the right power supply design is imperative for an overall successful product. With the ongoing goal of increased density, reliability, and efficiencies, power ratings need to be reviewed carefully. Product life, temperature, input voltage, load, and cooling are vital considerations,
The Qi standard is the only non-proprietary solution for wireless charging available in products today. It works by generating a safe electromagnetic field between a charger and a device through a well-established process called magnetic induction. Qi chargers have a built-in transmitting coil, so any Qi device will work with any Qi charger, now and in the future.
Wireless power is slowly evolving to help make charging second-nature to the consumer. In Japan, for instance, several portable devices are available that support wireless charging.As more portable devices that offer wireless charging capabilities enter the market, the need for standards naturally will follow.
Touchscreens are everywhere! While the means by which they detect a touch has evolved over the years, more recently you might say they have revolved as old technologies are reopened and rechristened anew. (I’m looking at you, optical touch.) Touchscreens are finding their way into our homes and our everyday consumer devices.
Sensors have been an important addition to smartphones ever since accelerometers were first used to determine screen orientation. Now a wide variety of sensors, including magnetometers, barometers, and gyroscopes, are found in many other devices, such as watches, glasses, headsets, and shoes.
New construction materials and techniques enable LVDT linear position sensor operation in diverse environmentsApril 30, 2013 3:04 pm | by Lee Hudson, Applications Engineer, Macro Sensors, www.macrosensors.com | Macro Sensors | Comments
The LVDT Linear Position Sensor is a robust sensor adaptable to a variety of applications. A very reliable sensing device with no moving parts, LVDTs are often the best linear feedback technology when it comes to reliability and longevity. However, in the past, LVDTs were limited by its own sensitivity to the environment that caused errors in linear feedback.
Accurate measurement of low pressure with respect to atmospheric reference (typically called vented or gauge reference) requires that pressure sensors breathe under dry, humid and wet conditions. In humid and wet environments, challenges are posed on how to operate the pressure sensor without allowing water into the back end of the sensors....
Solid state lighting is continuing its solid growth across a range of industries and applications. ECN recently spoke to Robbie Paul, Lighting Sales Director at Digikey to discuss the solid state lighting market and the latest LED trends.
Cold weather has been hanging on well into April here in the northeast. But if you were in Philadelphia this week, you would be forgiven for walking around wearing sunglasses – especially indoors at the Pennsylvania Convention Center – a sure sign that Lightfair is in town.
RGB LEDs are becoming increasingly popular for applications inside vehicles. For reasons of style and personalisation, as well as driver comfort and safety, they present an exciting opportunity for interior designers at major car makers. As multiple light points are required inside the vehicle in order to achieve the implementation of an effective solution....
