LSI Assigned Two Patents

Optical disk playback device
with three-dimensional playback functionality

United States Patent and Trademark Office has received an application no. 20130100788, on April 25, 2013, by LSI Corp., Milpitas, CA, titled as "Optical disk playback device with three-dimensional playback functionality" for the registration of patent.

Inventors are Freund Joseph Michael, Fogelsville, PA, and deGarrido Diego P. (Langhorne, PA).

Abstract: "An optical disk playback device comprises one or more lasers, an optical assembly, an optical detector, and controller circuitry coupled to the optical detector. The optical assembly is configured to direct incident light from the one or more lasers so as to form first and second scanning spots on a surface of an optical disk, and is further configured to direct corresponding reflected light from the first and second scanning spots on the surface of the optical disk to the optical detector. The optical detector is configured to process the reflected light from the first and second scanning spots to generate respective first and second data streams, and the controller circuitry is configured to generate a three-dimensional image signal from the first and second data streams."

The patent was filed on October 24, 2011 under application No. 20130100788

Error correction capability adjustment
of LDPC codes for storage device testing

LSI Corp., San Jose, CA, has been assigned a patent (8,413,029) developed by Richard Rauschmayer and Hongwei Song, Longmont, CO, for an "error correction capability adjustment of LDPC codes for storage device testing."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods and structure described herein provide for adjusting an error correction capability of an LDPC ECC. For example, the system of one embodiment includes a decoder adapted to decode data that has been encoded with a LDPC ECC. The system also includes a detector communicatively coupled to the decoder and adapted to estimate bit values in the data prior to decoding by the decoder. The detector is further adapted to change bit values based on bit value estimations to reduce the error correction capability of the LDPC ECC. The reduction in error correction capability is adjustable such that sector failure rates of storage devices may be incrementally analyzed."

The patent application was filed on March 11, 2009 (12/402,359).
