A sensor for a control panel, including a housing along an edge of the panel, light emitters projecting light along an in-air detection plane over the panel and detectors detecting reflections of the projected light, reflected by an object in the detection plane, lenses oriented such that each detector receives maximum light intensity when light enters a corresponding lens at a particular angle, whereby for each emitter-detector pair, when the object is located at a specific position in the detection plane, light emitted by the emitter of that pair is reflected by the object back through one of the lenses at the particular angle to the detector of that pair, the specific position being associated with that emitter-detector pair, and a processor configured to determine panel locations, map each location to a position in the detection plane associated with an emitter-detector pair, mapping the panel to the detection plane.

Object detector based on reflected light

A modular proximity sensor including a plurality of sensor modules, each sensor module including a housing, lenses, light detectors, each detector positioned along the image plane of a respective lens so as to receive maximum light intensity when light enters the lens at a particular angle, light emitters, each emitter positioned in relation to a respective lens so as to project light into a detection zone, an activating unit synchronously co-activating each emitter with at least one of the detectors, and a calculating unit receiving detector outputs corresponding to amounts of projected light reflected by an object in the detection zone, and calculating a two-dimensional location of the object in the detection zone based on the detector outputs and the particular angle, wherein neighboring sensor modules monitor different detection zones, and a processor receiving outputs from each sensor module and mapping the object location in multiple detection zones over time.

Optical proximity sensors

A proximity sensor, including a housing, an array of lenses mounted in the housing, an array of alternating light emitters and light detectors mounted in the housing, each detector being positioned along the image plane of a respective one of the lenses so as to receive maximum light intensity when light enters the lens at a particular angle, an activating unit mounted in the housing and connected to the emitters and detectors, synchronously co-activating each emitter with at least one of the detectors, each activated emitter projecting light out of the housing along a detection plane, and a processor receiving outputs from the detectors corresponding to amounts of projected light reflected by an object in the detection plane to the detectors, and calculating a two-dimensional location of the object in the detection plane based on the detector outputs and the particular angle.

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

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

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.
