Filed:

Jun 8, 2007

Appl. No.:

11/760150

Inventors:

Stephen W. Horton - San Diego CA, US
Timothy James Yates - San Marcos CA, US
Charles Seunghwan Han - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H04B 1/38

US Classification:

455557, 370408, 358 115, 709218, 455434, 4554566

Abstract:

Methods and apparatus for enabling output from a mobile device are described herein. A mobile device having an image capture device can selectively generate a hard copy output of a captured image by interfacing with an output device. The mobile device can selectively interface with the output device directly or indirectly via one or more intermediate devices and/or systems. The mobile device can interface directly with an output device using a wired or wireless connection, and can selectively operate as a host or client. The mobile device can selectively couple the stored image to a remote output device via a wireless connection. The mobile device can select the remote output device from a predetermined list of devices, or can be supplied a dynamic list of remote output devices. The dynamic list of output devices can be updated, for example, based on a location of the mobile device.

US Classification:

23546231, 23546206, 23546244

Abstract:

This disclosure describes barcode scanning techniques for an image capture device. The image capture device may automatically detect a barcode within an image while the image capture device is operating in a non-barcode image capture mode, such a default image capture mode. In one aspect, the detection of the barcode within the image may be based on a combination of identified edges and low intensity regions within the image. The image capture device may configure, based on the detection of the barcode, one or more image capture properties associated with the image capture device to improve a quality at which the images are captured. The image capture device captures the image in accordance with the configured image capture properties. The techniques may effectively provide a universal and integrated front-end for producing improved quality images of barcodes without requiring significant interaction with a user via a complicated user interface.

Abstract:

An x-ray imaging device. One surface of a flat single crystal CsI crystal is supported on an optically transparent support plate. The opposite surface, i. e. an x-ray illumination surface of the crystal is coated with an x-ray transparent optical reflector to provide an x-ray scintillation sandwich having an optical mirror at the x-ray illumination surface of the CsI crystal. An optical camera is preferably focused on the illumination surface of the CsI crystal. In a preferred embodiment an index of refraction matched optical adhesive is used at the x-ray illumination surface to attach the reflector and to reduce Fresnel reflections.
