Patent number: 7882149Abstract: Disclosed are arrangements which seek to update schemas in a controlled manner so that a device (3710) or service can accurately parse documents conforming to a new version of a schema (3724, 3734) without the need for translation services or extra information within the document to provide guides for translation. One embodiment provides a “best-effort” attempt to process documents of an unknown schema, based on a defined similarity threshold, instead of rejecting such documents as being invalid. The arrangements disclosed seek to provide a satisfactory output from an input document that conforms with an unexpected schema. A method for constraining evolution of a schema associated with a markup language includes the steps of defining the schema and defining a metaschema associated with the schema. The metaschema provides rules for valid changes to the schema.Type: GrantFiled: November 29, 2005Date of Patent: February 1, 2011Assignee: Canon Kabushiki KaishaInventors: Peter Reeve Foster, John Charles Brook, Nigel David Peter Eke

Publication number: 20110002242Abstract: Sparse channel equalization may be achieved by receiving a signal via a multi-path communication channel. The equalization then continues by extracting sparse information regarding the multiple path communication channel from the signal. Such sparse information generally indicates the position of the signals received via each of the multiple paths. The equalization then continues by estimating a channel response of the multiple path communication channel based on the sparse information. The equalization then continues by generating equalization taps (or coefficients) based on the channel response. The equalization then continues by equalizing the signal based on the equalization taps.Type: ApplicationFiled: March 12, 2003Publication date: January 6, 2011Inventors: Randall Perlow, Nabil Yousef, Charles Brooks, Tianmin Liu

Patent number: 7701515Abstract: A front end circuit for a television receiver includes a demultiplexer for inputting a multi-band signal from a signal source and separating the multi-band signal into corresponding bands. A plurality of amplifiers adjust gain on signals corresponding to the bands. A multiplexer combines outputs of the amplifiers into a gain-adjusted signal. A plurality of switches direct selected bands to corresponding tuners. The amplifiers are low noise amplifiers. The amplifiers adjust gain between the bands so as to have similar signal strength in the bands. A cable TV input may also be used, wherein the switches also direct signals from the cable TV to the corresponding tuners. Each amplifier can output two (or more) identical signals for its corresponding band, the multiplexer can be a dual multiplexer, and an output of the multiplexer includes only bands selected for direction to the tuners.Type: GrantFiled: July 2, 2004Date of Patent: April 20, 2010Assignee: Broadcom CorporationInventors: Ramon A.

Publication number: 20100073572Abstract: An apparatus and method is disclosed for adjusting a gain of an amplifier assembly array. The amplifier assembly array includes a first stage to provide an amplified signal based upon an input signal. The first stage has a variable gain controlled in response to one or more gain control signals. An Automatic Gain Control (AGC) module generates the one or more gain control signals according to a ramp function in response to a power level of the amplified signal. The first stage may include a first low noise amplifier (LNA) to amplify the input signal to provide a first amplified input signal and a second LNA to amplify a second input signal to provide a second amplified signal. A switch selects between the amplified signal and the second amplified signal to provide the amplified signal. The amplifier assembly array may additionally include a second stage to provide a second amplified signal based upon the amplified signal.Type: ApplicationFiled: November 19, 2009Publication date: March 25, 2010Applicant: Broadcom CorporationInventors: Lawrence M.

Patent number: 7634244Abstract: A multi-stage amplifier assembly configured to receive a terrestrial digital television (“DTV”) input signal including multiple frequency channels. The amplifier assembly optionally includes a PIN diode coupled across differential inputs to a first stage of the multi-stage amplifier assembly. The PIN diode is controlled to attenuate the input when an exceptionally large signal is present in a channel adjacent to a desired channel. The PIN diode, essentially a variable resistor, permits the multi-stage amplifier assembly to maintain dynamic range in such situations for reasonable tradeoffs. The amplifier assembly further optionally includes an out-of-band second stage LNA. The amplifier assembly further optionally includes a multi-band input filter. The multi-band filer insures that the AGC operates on the TV band of interest, thus improving the linearity of the system. The invention can be implemented in CMOS and/or SiGe.Type: GrantFiled: May 31, 2005Date of Patent: December 15, 2009Assignee: Broadcom CorporationInventors: Lawrence M. Burns, Charles Brooks, Leonard Dauphinee

Publication number: 20090119732Abstract: A second coaxial-connector may be added to a TV receiver that directly samples digital or analog format TV signals, which may be received via a first coaxial-connector. The second coaxial-connector may enable backwards compatibility with one of plurality of available consumer audiovisual devices, wherein Audio/Video (A/V) analog and/or digital modulation format feeds from the consumer audiovisual device may be inputted directly into the TV receiver via the second coaxial-connector. The A/V feed from the consumer audiovisual devices may be demodulated via a common demodulator for similarly modulated TV signals in the TV receiver. Filtering and/or amplification of the local A/V feed may be performed via dedicate components; however, analog-to-digital conversion of the local A/V feed may either be performed via the dedicated converter or via a common-path converter. The local A/V feed may also be demodulated directly, via a dedicated demodulator.Type: ApplicationFiled: November 2, 2007Publication date: May 7, 2009Inventors: Thomas Spieker, Charles A. Brooks

Patent number: 7468805Abstract: Methods and apparatus for proofing (644) a variable document intended for printing are disclosed in which a GUI (2000) is configured to allow user manipulation of layout rules associated with content containers within a template for variable document generation. Selective proofing (2100) involves proofing a plurality of variable data documents each formed from a common layout in which variable data content is placed into containers having locations and sizes within the layout and defined by layout rules. Measures of variation (2103, 2106) and measures of deviation (2109, 2110) are calculated. The measures of deviation are processed (2112) to give a deviation value. Once completed for each document, the deviation values of the documents are compared (2114) to identify at least one group of the documents for presentation for further assessment. Live proofing includes creating a layout (2002) for a variable data document based upon a template established in the GUI.Type: GrantFiled: July 14, 2004Date of Patent: December 23, 2008Assignee: Canon Kabushiki KaishaInventors: Andrew James Lo, John Charles Brook, Alan Valev Tonisson, Lachlan James Patrick
