Filed:

Oct 10, 2006

Appl. No.:

11/539985

Inventors:

Lin He - Los Angeles CA, US
Tong Fang - Morganville NJ, US

Assignee:

Siemens Medical Solutions USA, Inc. - Malvern PA

International Classification:

G06K 9/00
G06K 9/36

US Classification:

382128, 382280

Abstract:

Certain exemplary embodiments can comprise a method, which can comprise providing machine instructions adapted to render a final enhanced image of an object based upon a final enhanced set of data. The final enhanced set of data can be derived from a detected set of data obtained from an imaging device, such as a medical imaging device.

Nov 17, 2008

Appl. No.:

12/272556

Inventors:

Lin He - Irvine CA, US
Thomas J. Kolze - Phoenix AZ, US
Gottfried Ungerboeck - Langnau a.A., CH
Bruce J. Currivan - Dove Canyon CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04N 7/12
H04N 11/02

US Classification:

37524026

Abstract:

A method and apparatus is disclosed to map a sequence of data to Quadrature Amplitude Modulation (QAM) constellation symbols. The method and apparatus encodes only a portion of the sequence of data and leaves a remaining portion of the sequence of data unencoded. The encoded portion of the sequence of data and the remaining unencoded portion of the sequence of data are then mapped into modulation symbols of the QAM constellation. The encoded portion of the sequence of data selects subsets of the QAM constellation, and the remaining unencoded portion of the sequence of data determines a specific modulation symbol within each subset of the QAM constellation.

International Classification:

H03M 1/06

US Classification:

341118

Abstract:

Various pipeline ADCs are disclosed that substantially compensate for interference or distortion that results from imperfections with various ADC modules of the pipeline ADCs. The pipeline ADCs include various ADC stages and various compensation stages that are coupled to the various ADC stages. The various ADC stages convert their corresponding analog inputs from an analog signal domain to a digital signal domain to provide various digital output signals and various analog residual signals to subsequent ADC stages. The various compensation stages compensate for interference or distortion that is impressed onto the various analog residual signals which results from imperfections within previous ADC stages.

Abstract:

Systems and methods for cable transmission are provided. The system includes an up-tilt circuit, a digital-to-analog converter, and a power amplifier. The up-tilt circuit is configured to receive an input digital signal that has a flat spectrum and generate an up-tilted digital signal that has an up-tilted spectrum. The digital-to-analog converter is configured to receive the up-tilted digital signal and to provide an analog signal. The power amplifier is configured to receive the analog signal and amplify the analog signal for cable transmission.
