Error Detection/correction And Fault Detection/recovery > Pulse Or Data Error Handling Pulse Or Data Error HandlingPulse Or Data Error Handling patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/15/07 - 20070266274 - Interleaver and de-interleaver An interleaver employs a generalized method of generating a mapping. The mapping is generated for interleaving bits of a data block and associated error detection/correction information. The data block is of length N, and the length of the error detection/correction information is P. An (N+P)×(N+P) square matrix is formed and ... 11/08/07 - 20070260944 - Decoding ldpc (low density parity check) code and graphs using multiplication (or addition in log-domain) on both sides of bipartite graph Decoding LDPC (Low Density Parity Check) code and graphs using multiplication (or addition in log-domain) on both sides of bipartite graph. A means for decoding LDPC coded signals is presented whereby edge messages may be updated using only multiplication (or log domain addition). By appropriate modification of the various calculations ... 10/11/07 - 20070240021 - Method, system and program product for autonomous error recovery for memory devices An autonomous error recovery approach is provided for a memory device of a computing system. In response to a request for data, addressed data and associated control information of the memory device are tested for error. If error is detected, the contents of an addressed storage compartment of a second ... 09/27/07 - 20070226549 - Apparatus for detecting errors in a communication system A communication network switch comprises a control module having a control processor and a plurality of communication modules connected to the control module via a control interface. Each communication module comprises a detector for detecting errors associated with communication signals such as read and write access requests received from the ... 09/06/07 - 20070208966 - Test circuit for semiconductor device A semiconductor test circuit includes an input terminal, a controller, a setting circuit, a command generator, a transmission path switching circuit and a comparator. The input terminal receives a serial data including a command code and a control data. The controller receives a control signal and outputs an internal control ... 08/30/07 - 20070204188 - Error correction method and reproduction apparatus A reproduction method includes a step of performing error correction of the first coded data piece and generating error location information which represents an error location of the first coded data; a step of generating erasure locator information which represents an erasure position of the second coded data piece, based ... 06/28/07 - 20070150774 - Maintaining data integrity in a data storage system A method of recovering data on a storage medium is provided. A first error correction scheme is performed on a high risk region of the storage medium. A second error correction scheme is performed on a remaining portion of the storage medium. ... 05/03/07 - 20070101209 - Method of error correction for a series of marks on an optical disc A series of marks on an optical disc are sampled to yield a series of data pulses. The marks are at least substantially angularly equidistant to one another on the optical disc. A function is performed on the series of data pulses to yield an error-corrected series of data pulses. ... 01/04/07 - 20070006052 - Method for storing information on an optical disc A method is described for storing information on an optical disc, wherein data is encoded to form ECC blocks, and wherein the ECC blocks are written in predefined writing zones (Z) between run-in/run-out fields. According to the present invention, two or more ECC blocks are written between a run-in field ... 12/21/06 - 20060288262 - Optical disc reproducing apparatus When an error arises during the reproduction of a file from an optical disc, the error is detected by error detecting means, and the cause of the error is discriminated by error discriminating means. If the cause discriminated by the error discriminating means suggests that the error has arisen during ... 12/14/06 - 20060282710 - Event-generating instructions An information carrier medium containing debugging software that, when executed by a processor, causes the processor to generate an event signal and an event code and provide the event signal and the event code to an event detection logic coupled to the processor. The event detection logic is adapted to ... 07/13/06 - 20060156079 - Shift register system, driving method, and driving circuit for a liquid crystal display An exemplary shift register system (31) includes a counter (316), a shift register (311) and a plurality of switches (312, 313, 314, 315).
