Abstract: The present invention is directed roof edge seal and barrier devices and their method of manufacture. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier comprises stamping or cutting an elongate strip of material along a sinuous path located between the edges of the strip and then separating the strip into two portions, each of which consists of a fixing edge corresponding to the edge of the original strip from which project a series of teeth or prongs forming a comb structure.

Abstract: Approaches are disclosed for encoding N symbols of a sequence in parallel using an R parity symbol encoding algorithm. A first symbol matrix is added to a first parity matrix over a finite field to produce a first intermediate matrix. The first intermediate matrix is multiplied by at least a first coefficient matrix and a second coefficient matrix over the finite field to produce a second intermediate matrix. A second symbol matrix is multiplied by at least the second coefficient matrix to produce a third intermediate matrix. The second and third intermediate matrices are added to produce a revised parity matrix.

Abstract: In one embodiment, an encoder circuit is provided. The encoder includes an input circuit having a plurality of finite field subtraction circuits, each configured to receive a respective one of the sequence of symbols and subtract the symbol from a respective symbol of an intermediate polynomial to produce a respective feedback symbol. For each coefficient of a code generation polynomial, a first circuit is configured to multiply each feedback symbol by a respective constant corresponding to the coefficient to produce a first set of intermediate results. Each first set of intermediate results is summed to produce a second intermediate result. A buffer circuit of the encoder is configured and arranged to store the second intermediate results produced by the first circuit as the intermediate polynomial.

Abstract: In one embodiment, a multi-stage decoder circuit is provided. Each stage of the decoder circuit is configured to perform one or more decoding iterations and produce an error mask indicating errors detected in the decoding stage. A compression circuit is coupled to one or more of the decoder stages and is configured to generate, for each of one or more of the plurality of decoder stages, a respective compressed error mask from the error mask produced by the decoder stage. A buffer circuit is coupled to the compression circuit and is configured to buffer the compressed error masks. A decompression circuit is coupled to the buffer circuit and is configured to decompress each of the compressed error masks. A combination circuit is coupled to the decompression circuit and is configured to combine the decompressed error masks into a single error mask.

Abstract: An example apparatus for replacement of a breached pipe section includes a first cylindrical pipe fitting having a first surface defining a first aperture, a middle pipe member, and a second cylindrical pipe fitting having a second surface defining a second aperture, and first and second aperture caps. A first end of each of the first and second pipe fittings is welded to opposite ends of the middle section, and a second end opposite of each of the first and second pipe fittings is welded through the respective first and second apertures to opposite ends of pipe surrounding the breached pipe section. The first and second aperture caps are welded to the apertures of the first and second pipe fittings to close the respective first and second apertures.

Abstract: An air conditioning system for providing air conditioning to the interior of an automotive vehicle with a mixing chamber designed to create, by controlled mixing of a warm and of a cool partial air flow, at least one warmer and one cooler air-conditionable air flow. The flow paths of the warm partial air flow and of the cool partial air flow intersect in the mixing chamber.

Abstract: The present invention is a multiple zoned air conditioning system for providing air conditioning to the interior of an automotive vehicle. The air conditioning system includes a main air conditioning module with a first heat exchanger for cooling and with a second heat exchanger for heating, as well as a multiple zone module. The main air conditioning module creates, in cooperation with the multiple zone module, at least one first air flow conditioned for temperature. The multiple zone module is interchangeably disposed in the main air conditioning module, with the second heat exchanger engaging the multiple zone module so as to allow air flow therethrough, when the multiple zone module is disposed on the main air conditioning module.
