Appl. No.:

12/619427

Inventors:

Huinan J Yu - Kildeer IL, US
Jun Jiang - Lake Zurich IL, US
John R St. Peter - Elburn IL, US

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.

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:

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.
