A first comparator makes a comparison between potentials on paired signal lines connected with the secondary winding of a transformer to produce a signal indicating whether data of a first value has been received or not. A second comparator makes a comparison between potentials on the paired signal lines to output a signal indicating whether data of a second value has been received or not. A first detector samples the output signal of the first comparator at regular sampling intervals to produce...

A method for communicating data is provided that includes storing one or more physical connectors associated with an input/output card and configuring the input/output card to a selected one of a slave, master, and passive mode. An identification for the input/output card may be provided to an end user, the identification reflecting a selected configuration parameter associated with the input/output card.

A smart switch design in an external data storage or a flash memory reader/writer application that controls a power on/off to both a data storage device and an electronic bridge board inside a interface cable, the external data storage including: an enclosure for protecting interior elements; a switch with first and second ends, the first end connected to a wire of the electronic bridge board for receiving a power signal from a computer via an interface cable, the second end is connected to a po...

A method and system for allocating pre-selected physical memory locations to an application executing on a data processing system. Memory allocation subroutines, interacting with the programming interfaces of the operating system (OS), allocates and looks down blocks of memory. The memory allocation subroutines then de-allocates the memory blocks based on whether or not the memory blocks fall within the pre-selected range of physical memory locations. The physical memory locations of the blocks ...

A method for decoding Low Density Parity Check (LDPC) codes comprises executing a sum product algorithm to recover a set of information bits from an LDPC code represented as a bipartite graph of symbol nodes and check nodes, the sum product algorithm being responsive to input log likelihood ratios associated with the symbol nodes. The check nodes are updated by generating a set of forward difference metrics and a set of backward difference metrics in dependence on the ratios of logarithmic proba...

A method of generating low density parity check codes for encoding data includes constructing a parity check matrix H from balanced incomplete block design (BIBD) in which a plurality B-sets which define the matrix have no more than one intersection point. The parity bits are then generated as a function of the constructed parity check matrix H.

Provided are methods and apparatuses for decoding input data by using a single decoder for decoding a first set of symbols and then, after those decoded symbols have been interleaved, using the same decoder for decoding the decoded and interleaved first set of symbols together with a second set of symbols. Also provided are methods and apparatuses for decoding input data by using multiple read/write means for controlling the storage and reading of data so as to interleave and/or de-interleave da...

A computer-implemented method for viewer-specific presentation of information. The method includes a first step of receiving a request for information from a viewer. A viewer state associated with the viewer is then identified. The viewer state then provides a list of one or more data states in a ranked order of preference for satisfying a request for information for said viewer state. A data store contains data elements of a variety of data types, each data element tagged with a specific data t...

A protective face mask with a facial covering sheet is formed of an impact-resistant transparent sheet to match the contour of a face. The mask has mirror image eye openings that are open-sided, a mouth opening and an array of ventilation openings adjacent to the bottom of the nose of the wearer. A forehead pad and a pair of cheek pads are adhered to the inner surface of the mask to absorb impact. A set of elastic straps are provided to securely hold the mask onto the head of the wearer.

A glove with protective padding for a wrist covers a dorsal side of the wrist excluding the radio styloid, the Lister's tubercle, and the distal ulna.
