20090109048Wireless surface acoustic wave-based proximity sensor, sensing system and method - The subject invention is related to wireless proximity sensor and sensing system for detecting the position of an object. The system includes a transceiver for providing wireless communication with a passive wireless surface acoustic wave (SAW) proximity sensor. The wireless proximity sensor receives a wireless signal from the transceiver, which powers the SAW device and in turn transmits a signal back to the transceiver that includes information about the position of an object.

20110006907System and Method for Detecting the Presence of an Object - In a reflection type proximity detector or method, a controller calculates a calibration value based on ambient conditions with the transmitter off and then performs tests. In each test, the calibration value is added to and subtracted from a measured value taken with the transmitter in one state (on or off) and a second measured value is then taken and compared with this range. In tests where the transmitter is switched from off to on between the measurements and the second value exceeds the range, and tests where the transmitter is switched from on to off between the measurements and the second value is below the range, an object is detected. When the transmitter does not switch states between the measurements, and the second value is less than or greater than the range, then no object is detected, as the change in measured value likely resulted from an outside signal.01-13-2011
