Appl. No.:

12/619427

Assignee:

Motorola Mobility LLC - Libertyville IL

International Classification:

G06K 7/00
G06K 15/00

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:

F02K 3/00

US Classification:

60 39163

Abstract:

A gas turbine engine includes a spool, a turbine coupled to drive the spool and a propulsor that is coupled to be driven by the turbine through the spool. A gear assembly is coupled between the propulsor and the spool such that rotation of the spool drives the propulsor at a different speed than the spool. The propulsor includes a hub and a row of propulsor blades that extends from the hub. The row includes no more than 16 of the propulsor blades.

US Classification:

Abstract:

In one embodiment, a method for controlling a liquid crystal display (LCD) is provided. The method receives a first light from a light source structure at a light emitting layer and emits from the light emitting layer a first color component, a second color component, and a third color component. The method then receives a second light through a first polarizer layer of a first polarization state positioned above the light emitting layer, a liquid crystal layer positioned above the first polarizer layer, and a second polarizer layer of a second polarization state positioned above the liquid crystal layer and converts the second light into the first color component, the second component, and the third color component in the light emitting layer. An intensity of the first light is dynamically controlled based on the converting of the second light.
