Abstract: A wireless status indicator for a wireless power transfer system includes an object configured to wirelessly generate power responsive to a magnetic flux field of a wireless power transmitter and to generate a status indication of the wireless power transfer system. A wireless power transfer system comprises a wireless power status indicator configured to wirelessly generate power responsive to a wireless power signal and to generate a status indication of the wireless power transfer system. A related method includes generating power by a wireless status indicator and generating a status indication responsive to a wireless power signal. The wireless status indicator is a separate stand-alone device than a wireless power transmitter and wireless power receiver involved in the wireless power transfer. The status indication corresponds to a state of wireless power transfer.

Abstract: Embodiments relate to a proximity sensor, particularly for mobile devices like smartphones, tablets or the like. The proximity detector includes a first emitter-detector pair with a first light emitter and a first photodetector, wherein the first light emitter and the first photodetector are separated by a first distance, and a second emitter-detector pair with a second light emitter and a second photodetector, wherein the second light emitter and the second photodetector are separated by a second distance, wherein the first distance is different from the second distance. Embodiments further relate to a method for detecting the proximity of a target to a proximity sensor.
