Proximity sensor with motion detection

A proximity sensor with movement detection comprising:

• a sensor module comprises at least three light sources configured to emit light and a photo detector configured to receive light and generate an output signal;
• and
• a controller module coupled to the sensor module comprising control logic and a comparator;
• wherein the comparator is 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 sensor module;
• 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 sensor module, respectively.

A detector comprising:

• a sensor module comprising a plurality of light sources configured to emit light and a photo detector configured to receive light and generate an output signal;
• a controller coupled to the sensor module and comprising control logic and a comparator;
• a counting engine coupled to the controller configured to register predetermined movements of an object;
• wherein the sensor module comprises at least three light sources disposed adjacent to three sides of the sensor module in a triangular pattern;
• and
• a substantially clear epoxy material covering the at least three light sources and forming a lens over each of the at least three light sources and a casing covering the epoxy material to form a detector package, wherein the detector package comprises apertures over the at least three light sources and the photo detector.
