Patent ID: 8619267

Claim:
A proximity sensor with movement detection comprising: an ASIC chip; at least three light sources configured to emit light in a predetermined sequence; and a photo detector configured to receive light and generate an output signal; wherein the photo detector is stacked on the ASIC chip and disposed at a substantially equal distance from the at least three light sources; wherein the ASIC chip comprises a comparator configured to report a movement upon determining the presence of a predetermined profile in the motion signal, wherein the predetermined profile is a profile of a motion signal generated by the control logic in correspondence to a certain movement of an object over the proximity sensor; wherein the comparator is configured to report a movement if the profile of the motion signal generated by the control logic matches one of the predetermined profiles from among a set of known motion signal profiles; and wherein the known motion signal profiles comprise horizontal and vertical motion signal profiles corresponding to movements of an object along the X-axis and the Y-axis over the proximity sensor, respectively.
