There are a number of ways to construct accelerometers, but the ones in the iPhone (and probably most other consumer-level equipment) specifically are MEMS accelerometers. As I understand it, a change ...
You put it up to your ear and the screen goes blank. Turn it on its side, and the screen rotates. Walk outside and it can find your location, point a compass in the correct direction and post your ...
In a conference room at Analog Devices (ADI), Howard Wisniowski holds a demo board a little bigger than a commemorative stamp about a meter above the table top. An ADI motion sensor and associated ...
Have you ever wondered how your iPhone knows up from down, or when you’re shaking it? It’s all because of the tiny accelerometer chip inside the device, but how does it work? It’s not like the ...
How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...
Researchers at the National Institute of Technology (NIST) have developed a new type of accelerometer based on lasers and optomechanical principles rather than the traditional mechanical strain gauges ...
