A newly published patent application from Apple describes a way in which the iPhone would automatically lower or raise its volume based on how close you are to the device. Lance Whitney is a freelance ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

One of the major issues surrounding the iPhone 4 release this summer was the proximity sensor failing during phone calls resulting in muting, conference calling, and other inadvertent touch input.

Today, the U.S. Patent and Trademark Office has approved an Apple patent that enables the utilization of various phone sensors to automatically adjust the output volume and turn on the device's other ...
