An input panel for an electronic device, including an arrangement of buttons, wherein each button is actuated when pressed, providing input to an electronic device, and a sensor, detecting location of a user's finger above the buttons, the sensor including a housing, a printed circuit board, light emitters and photodiode detectors, lenses mounted in the housing in such a manner that, when the housing is mounted along an edge of the arrangement, the lenses direct light from the emitters along a plane above the buttons, and direct light from the plane, reflected toward the lenses by an object inserted into the plane, onto the detectors, a processor configured to identify a location in the plane at which the object is inserted based on the detections of light reflected by the object, and a communications port configured to output the identified location to the electronic device.

Contactless control panel

A sensor, including light emitters projecting directed light beams, light detectors interleaved with the light emitters, lenses, each lens oriented relative to a respective one of the light detectors such that the light detector receives maximum intensity when light enters the lens at an angle b, whereby, for each emitter E, there exist corresponding target positions p(E, D) along the path of the light from emitter E, at which an object located at any of the target positions reflects the light projected by emitter E towards a respective one of detectors D at angle b, and a processor storing a reflection value R(E, D) for each co-activated emitter-detector pair (E, D), based on an amount of light reflected by an object located at p(E, D) and detected by detector D, and calculating a location of an object based on the reflection values and target positions.

Optical proximity sensor and associated user interface

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.
