Abstract: Various embodiments are described that relate to directing of a signal. An incoming signal can be compared to a threshold voltage. If the signal does not meet the threshold voltage, then the signal can be used for normal usage, such as communication with a software-defined radio. However, if the signal does meet the threshold, then the signal can be directed away from normal usage. In one example, the signal can be directed away from a communication component and directed to an energy harvesting component that charges a battery of the software-defined radio.

Abstract: ForcePhone is a novel system for enabling phones to recognize the force applied to their touchscreen and/or body. ForcePhone uses built-in sensors to measure the applied force via a physical property called structure-borne sound propagation. The phone plays an inaudible sound through the phone's speaker. When the phone is free to vibrate, the sound from the speaker easily travels through its body to the phone's microphone. When a force is applied to the phone, vibration is restricted and the sound traveling through the pathway is degraded. ForcePhone estimate the amount of applied force by monitoring the change in sound degradation.

Abstract: Antenna switching circuitry includes an antenna node, a number of signal path nodes, and a number of switching elements. Each one of the switching elements is coupled between a different one of the signal path nodes and the antenna node. At least two of the signal path nodes are coupled together in order to form a low distortion node, such that the switching elements between the low distortion node and the antenna node are used to pass a low-distortion radio frequency (RF) signal. By coupling two of the signal path nodes together, a low distortion signal path is created to the antenna. Creating a low distortion signal path using multiple switching elements allows for the size of the switching elements to remain small, which reduces the parasitic capacitance of each one of the switches and therefore the insertion loss of the antenna switching circuitry.
