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.

Optical proximity sensor

A user interface method for an automated door lock, including providing a sensor operable to identify two-dimensional locations of an object within a detection plane that extends outward from a door, providing an unlocker operative to automatically unlock the door, identifying, by a processor coupled with the sensor and the unlocker, a linear movement of the object within the detection plane, in a first direction of motion, further identifying, by the processor, a linear movement of the object within the detection plane, in a second direction of motion substantially orthogonal to the first direction of motion, and activating, by the processor, the unlocker in response to the identifying and the further identifying.

Door lock user interface

A system including two handheld electronic devices, each device including a housing, a communicator mounted in the housing continuously receiving images from an internet server, a display mounted in the housing, and a sensor mounted in the housing and connected to the communicator, configured to detect sizes of objects in an adjacent detection zone, and including an analyzer recognizing the other handheld electronic device when the sensor detects that an object in the adjacent detection zone is as long as an edge of the housing, wherein the server receives outputs from the analyzer and partitions each of the images into two half-images, and continuously transmits one of each half-image to the handheld electronic device and the other of each half-image to the other handheld device, such that each full image spans the two device displays.

Handheld electronic device and associated distributed multi-display system

Optical proximity sensor and associated user interface

A door handle including light emitters for emitting light out of the handle, light detectors, lenses oriented relative to the emitters and detectors such that for each emitter-detector pair, when a reflective object is located at a target position near the handle, corresponding to that emitter-detector pair, then the light emitted by that emitter passes through one of the lenses and is reflected by the object back through one of the lenses to that detector, a keyless lock that, when activated, scans for a digital key via wireless communication, and a processor operable to synchronously activate emitter-detector pairs, to recognize from the amounts of light received by the activated detectors, and from the target positions corresponding to the activated emitter-detector pairs, that the object is approaching the handle and performing a sweep gesture and, in response thereto, to activate the keyless lock.

Door handle with optical proximity sensors

Activating a plurality of light emitters and light detectors around a screen, each emitter-detector pair corresponding to a light path crossing the screen, wherein some of the light paths are blocked when one or more objects touch the screen, providing a look-up table, listing, for each cell from a plurality of cells, those light paths that traverse that cell when no object is touching the screen, wherein the cells partition the screen, for each cell: accessing the look-up table to identify those light paths that traverse that cell, determining whether the thus-identified light paths are blocked during the activating and, if affirmative, recognizing that cell as being a touched cell, and combining adjacent touched cells into a common touch location, thereby calculating one or more touch locations wherein each touch location is a combination of one or more constituent touched cells.

Optical touch screens

A proximity sensor including a housing, a plurality of light pulse emitters for projecting light out of the housing along a detection plane, a plurality of primary light detectors for detecting reflections of the light projected by the emitters, by a reflective object in the detection plane, a plurality of primary lenses oriented relative to the emitters and primary detectors in such a manner that for each emitter-detector pair, light emitted by the emitter of that pair passes through one of the primary lenses and is reflected by the object back through one of the primary lenses to the detector of that pair when the object is located at a position, from among a primary set of positions in the detection plane, that position being associated with that emitter-detector pair, and a processor for co-activating emitter-detector pairs, and configured to calculate a location of the object in the detection plane.

Proximity sensor for determining two-dimensional coordinates of a proximal object

A lens for placement opposite a diode in an optical touch sensor, including an upper portion including an upper refractive surface located nearer to the diode, and an upper reflector located further from the diode, the upper reflector being curved in two dimensions and cut horizontally by a top horizontal plane of the lens, and a lower portion, coplanar with the diode, including a lower refractive surface located nearer to the diode, and a lower reflector located further from the diode, the lower reflector being curved in the two dimensions and cut horizontally by a bottom horizontal plane of the lens, wherein the upper and the lower reflector are symmetrical and vertically aligned, and wherein non-collimated light reflected by the lower reflector onto the upper reflector is partially collimated in the two dimensions by the lower reflector and further collimated in the two dimensions by the upper reflector.
