Abstract: A sensor determining coordinates of a proximal object, including a one-dimensional array of alternating light emitters and detectors, including a plurality of light emitters projecting light along a detection plane, and a plurality of light detectors detecting reflections of the projected light, by a reflective object in the detection plane, and a plurality of lenses mounted and oriented relative to the emitters and the detectors such that the light detectors receive maximum intensity when light enters a corresponding lens at a first particular angle, whereby for each emitter-detector pair, light emitted by the emitter of that pair passes through one of the lenses and is reflected by the object back through one of the lenses to the detector of that pair when the object is located at one of a set of positions in the detection plane, that position being associated with that emitter-detector pair.

Abstract: An optical assembly including a reflectance-based sensor emitting light into a detection plane and detecting reflections of the emitted light, reflected by an object located in the detection plane, a light redirector positioned away from the sensor redirecting light emitted by the sensor into one or more spatial planes parallel to the detection plane and, when the object is located in the one or more spatial planes, redirecting light reflected by the object into the detection plane, and a processor controlling light emitted by the sensor and receiving outputs from the sensor, and configured such that when an object passes through one or more of the spatial planes, the processor identifies both the spatial planes through which the object passes, and the location of the object within the spatial planes through which it passes, based on the received outputs and the position of the light redirector relative to the sensor.

Abstract: 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.

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.

Abstract: A device including an elastic layer that, when depressed by an object, causes a local indentation in the layer, the geometry of the local indentation being in accordance with a force of depression, light emitters, light detectors, a light guide between the emitters and the layer directing light beams from the emitters into the layer at an angle such that the light beams, after entering the layer, remain confined to the layer by total internal reflection, a light guide between the detectors and the layer that directs light beams exiting the layer onto the detectors, each detector having a reference output value corresponding to expected light detection when no object is touching the layer, and a processor determining the object's force of depression based on the geometry of the local indentation in the layer, as calibrated by a deviation between actual and reference output values for one of the detectors.
