The EIR can be configured to perform outputting raw message data containing an encoded message and/or outputting decoded message data corresponding to an encoded message. The wireless communication interface can comprise a radio frequency front end configured to perform receiving a first radio signal and/or transmitting a second radio signal. The radio frequency front end can be electrically coupled to an analog-to-digital converter which can be electrically coupled to the system bus and/or to a digital-to-analog converter which can be electrically coupled to the system bus.Type: GrantFiled: September 25, 2009Date of Patent: October 18, 2011Assignee: Hand Held Products,Inc.Inventors: Ynjiun P. Wang, Huyu Qu, James T. Sauerwein

Patent number: 8033468Abstract: An image scanner apparatus, method and system to scan a bar code or other optical code using an image capture device where the blurring associated with the movement of the bar code pass the image scanner is reduced or eliminated by using differential panning of the bar code. An image of the bar code is panned or moved across the image capture device in a direction that negates at least some of the apparent movement of the bar code past the image scanner. The apparent motion of the bar code to the image capture device is reduced thus reducing the blurring of the bar code in the captured image.Type: GrantFiled: July 21, 2008Date of Patent: October 11, 2011Assignee: NCR CorporationInventor: Sik Piu Kwan

Patent number: 8028915Abstract: A current data capture system has a set of configuration parameters operative for enabling the current data capture system to capture transaction data. A configuration host is operative for pulling the set of configuration parameters from the current data capture system, and for pushing a pulled set of configuration parameters to at least one additional data capture system to enable the at least one additional data capture system to capture the transaction data.Type: GrantFiled: January 11, 2008Date of Patent: October 4, 2011Assignee: Symbol Technologies, Inc.Inventors: Robert James Pang, Kenneth S. Bhella, Viraj Jeevan Thameera Amarasekera, Christopher Warren Brock

Publication number: 20110215152Abstract: The present invention is directed towards systems and methods for decoding a bar code. Decoding the bar code includes segmenting the bar code into black tokens, white tokens and gray boundary pixels. Decoding the bar code also includes calculating a boundary position of each token with sub-pixel positional accuracy using intensity values of pixels in a boundary region.Type: ApplicationFiled: March 8, 2010Publication date: September 8, 2011Inventors: Eunice Poon, Jia Li, Seungsik Kwak, Mikhail Brusnitsyn

Patent number: RE43511Abstract: A device for individually processing each color component of a serial analog signal from a color scanner. The device includes a multiple-channel-image-capture circuit comprising an analog front end/digitizer having a plurality of channels operable to process an analog-color signal with one channel for each color component of the analog-color signal, a register, and an analog-to-digital converter operable to output a digital signal responsive to the analog-color signal, and a controller operable to control the color component processing by the plurality of input channels such that each color component of a serial analog-color signal is individually processed. Each input channel of the analog front end/digitizer may include a programmable circuit operable to modify a color component of the color signal in response to a value stored in the register related to the color component.Type: GrantFiled: January 31, 2007Date of Patent: July 17, 2012Assignee: Marvell International Technology, Ltd.Inventor: Douglas Gene Keithley
