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 steering wheel for a vehicle, including front and back semi-toroidal surfaces joined at their outer circumferences by a light guide in the shape of a circular rim, and enclosing a toroidal volume having a cavity therein, a PCB mounted in the cavity, an alternating array of invisible-light emitters and receivers mounted on the PCB, such that the light guide projects invisible-light beams emitted by the emitters radially outward of the steering wheel, and directs reflections of the projected light beams off of a driver's hands radially inward to the steering wheel toward the receivers, and a processor connected to equipment mounted away from the steering wheel, the processor synchronously activating each emitter with a respective neighboring receiver, identifying a driver's hand gestures along an arc of the light guide based on reflected light detected by the receivers, and controlling the equipment in response to the thus-identified hand gestures.

Light-based controls in a toroidal steering wheel

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 and associated user interface

A state machine for controlling a sensor including a chip package coupled with photo-emitters and photo-detectors mounted in a device, and with a host processor, including an emitter driver, a detector driver, a signal processor for generating signals representing amounts of light detected by the detectors, and a scan controller for controlling the emitter and detector drivers to activate an automated sequence of emitter-detector pairs, the scan controller including registers for storing parameters designating emitter-detector pairs that are to be activated during the automated sequence, and for storing the signals generated by the signal processor for the emitter-detector pair activations, and at least one input/output pin for receiving parameters from the host processor to be loaded into the registers, and for outputting the stored signals in the registers to the host processor, for the host processor to identify therefrom location coordinates of an object near or touching the device.

Light-based touch screen

A touch screen assembly including a display, infra-red light emitters, photo diodes, a transparent frame including an exposed upper edge along its perimeter, and internally reflective facets for directing light emitted by the emitters along light paths that travel upward through one side of the frame, over the display screen, downward through the opposite side of the frame, and onto the photo diodes, and a processor operative to identify a location of an object touching the display, based on amounts of light detected by photo diodes when light emitted by light emitters is blocked along its light path by the object, and to recognize the object touching an outer wall of the frame, based on amounts of light detected by activated photo diodes when light emitted by activated emitters is absorbed along its light path by the object at the outer wall, thereby providing touch sensitivity to the frame itself.

Integrated light guide and touch screen frame

A cover for a handheld electronic device, including a cover piece that fits over a side surface of a handheld electronic device, a plurality of proximity sensors mounted in the cover piece, and directed outward from the side surface, for detecting user gestures performed outside the side surface, wireless communication circuitry, and a processor configured to operate the proximity sensors, and to cause the wireless communication circuitry to transmit commands to the electronic device in response to gestures detected by the proximity sensors.

Curved light guide frame

Light guide frame

A touch screen including a housing, a display mounted in the housing, a plurality of collimating lenses mounted in the housing along two opposite edges of the display and arranged along the two edges so as to be shift-aligned relative to one another, a plurality of light pulse emitters mounted in the housing that are spaced apart from and transmit light pulses through the collimating lenses of one of the two edges over the display, a plurality of light pulse receivers mounted in the housing that are spaced apart from and receive the light pulses through the collimating lenses of the opposite of the two edges, and a calculating unit, mounted in the housing and connected to the receivers, that determines a location of a pointer on the display that partially blocks the light pulses transmitted by the emitters, based on outputs of the receivers.

Light-based touch screen with shift-aligned emitter and receiver lenses

A method for use by a touch screen in which light transmitted inside the screen is scattered by an object touching the screen from outside the screen, the method including activating emitter-receiver pairs for a plurality of emitters and receivers while an object is touching a screen from outside the screen, wherein light emitted by each emitter is transmitted inside the screen, wherein each emitter is associated with a limited number of receivers that detect significant light from such emitter while no object is touching the screen, and wherein the activated emitter-receiver pairs include pairs for which the receiver is not associated with the emitter in the pair, determining that receivers not associated with emitters detect significant light due to the object scattering the light emitted by the emitters, and deriving the location where the object is touching the screen from the determining.
