摘要： A proximity sensor with movement detection is provided. The proximity sensor may include an ASIC chip; at least three light sources configured to emit light in a particular sequence; and a photo detector configured to receive light and generate an output signal. The proximity sensor may have a compact size package, wherein the photo detector may be stacked on the ASIC chip and disposed at a substantially equal distance from the at least three light sources. The proximity sensor includes a driver operable to generate a current to a plurality of light sources in a particular timing sequence, a photo detector configured to receive light and generate an output signal, an ASIC configured to report the movement of an object near the proximity sensor if the output signal pattern generated matches one of the output signal patterns from among a set of known output signal patterns. The proximity sensor may be configured to be used as a counter or an on/off switch based on particular movements detected.

摘要： Various embodiments of a optical proximity sensor and corresponding methods of measuring crosstalk in the sensor are disclosed. The amount of crosstalk generated between the light emitter and the light detector of an optical proximity sensor is measured and quantified according to one of two methods. The measured crosstalk may then be stored in a register or memory location and then subtracted from signals representative of signals indicative of the nearby presence of an object to be detected combined with crosstalk, thereby removing so the contribution or effect of crosstalk on such signals.
