US Classification:

23546213, 23546201

Abstract:

Barcodes stored by mobile devices can be used in commerce. In sending barcode data optically from a display backlight of a mobile communication device to a barcode scanner optical receiver, the transmitted data bit time needs to be compatible with the frequency range the barcode scanner is designed to receive. The disclosed methods and mobile devices can send barcode data optically at different frequencies from a modulated display backlight to different models/makes of laser barcode scanners that may be used at a point of sale (POS). The disclosed are methods and devices for processing the bit time mix choices make a determination of bit time mix choices based upon predetermined criteria. Location of the device is an example of predetermined criteria. A location may have a particular bit time mix signature that may be accessed, for example, in a look up table.

International Classification:

G01J 5/02

US Classification:

250349

Abstract:

An infrared sensing assembly for allowing detection of a location of an external object, as well as a mobile device employing such an assembly and related methods of operation, among other things, are disclosed. In one exemplary embodiment, the sensing assembly includes a pyramid-type housing structure having a central surface and multiple outer surfaces each of which extends in an inclined manner away from the central surface. The sensing assembly further includes multiple phototransmitters each positioned proximate to a respective one of the outer surfaces, and a photoreceiver positioned proximate to the central surface, with each respective photoelectric device being oriented so as to correspond to its respective surface. The sensing assembly is operated so that light is emitted from the phototransmitters, reflected by the object, and received by the photoreceiver. By processing signals from the photoreceiver that are indicative of the received light, the external object's location is determined.

International Classification:

H04B 10/00

US Classification:

398135

Abstract:

An optical transceiver () can comprise an optical receiver (), an optical lens (), and an optical transmitter (). The optical lens can have a lateral periphery () and can be configured and arranged to focus at least some incoming light () at the optical receiver. The optical transmitter, in turn, can be disposed within a boundary defined by the lateral periphery of the optical lens and other than in a lateral plane that contains the optical receiver.

US Classification:

345173, 359613, 362555, 356615

Abstract:

A method for resolving blind spots associated with a proximity sensor provides an optical guide in cooperation with an isolator wall that separates a transmitting section and a receiving section of the proximity sensor. Additionally, a specific guide angle of the optical guide directs, towards a receiver, more light rays reflected off an external object than light rays transmitted from a light source in the transmitting section.

International Classification:

G06F 1/16
G06F 3/147
G06F 9/4401

Abstract:

An example computing device comprises a processor to be coupled to a display device, and a boot controller coupled to the processor and to be coupled to the display device. The boot controller is configured to detect a power signal, receive sensor data detected by one or more sensors prior to an operating system being loaded by a boot process of the processor, determine a posture associated with the display device based on the sensor data detected by the one or more sensors, and communicate, to the display device, posture information indicating the posture associated with the display device. Pre-boot content is to be displayed on a display panel of the display device in a first arrangement based on the posture information. In more specific embodiments, determining the posture includes determining at least an orientation of the display device and whether a peripheral is present on the display device.

International Classification:

G09G 3/20

Abstract:

The present disclosure is directed to systems and methods of reducing display image power consumption while maintaining image quality on display devices having a plurality of display power modes. Each display power mode has associated therewith a defined baseline value (K) first relationship. A display image includes a baseline percentage under-boosted pixels (X). Using the first relationship value (K) and the pixel percentage (X), a baseline second relationship value is determined (K). The value associated with the second relationship is adjusted to a first plurality of values. At each value, the value associated with the pixel percentage is adjusted to each of a second plurality of values. At each combination of second relationship value and pixel percentage, a respective first relationship value is determined. A first relationship value, second relationship value are selected to provide a reduced power consumption while maintaining image quality.
