  • Patent number: 10496180
    Abstract: A proximity sensor including a housing, light emitters mounted in the housing for projecting light out of the housing along a detection plane, light detectors mounted in the housing for detecting amounts of light entering the housing along the detection plane, whereby for each emitter-detector pair (E, D), when an object is located at a target position p(E, D) in the detection plane, corresponding to the pair (E, D), then the light emitted by emitter E is scattered by the object and is expected to be maximally detected by detector D, and a processor to synchronously activate emitter-detector pairs, to read the detected amounts of light from the detectors, and to calculate a location of the object in the detection plane from the detected amounts of light, in accordance with a detection-location relationship that relates detections from emitter-detector pairs to object locations between neighboring target positions in the detection plane.

  • Patent number: 9710144
    Abstract: A computer readable medium storing instructions which cause a processor to generate data structures for an object moving along the perimeter of a curved touch-sensitive user input device, each data structure corresponding to a gesture and including a time stamp, polar angles at which the object starts and ends, a middle polar angle of the object, and an assigned state being one of the group RECOGNIZED, UPDATED and ENDED, wherein the instructions cause the processor to assign the RECOGNIZED state to the data structure when the moving object is initially detected on the perimeter of the device, to assign the UPDATED state to the data structure when the moving object is further detected on the perimeter of the device after the initial detection, and to assign the ENDED state to the data structure when the moving object ceases to be detected on the perimeter of the device.
