Title: Fuel cell electrode manufacturing method
Inventor: KAKUTANI OSAMU
IPC: H01M4/92
Filed: 2002-11-26
Granted: 2011-01-25
Abstract: An electrode for a fuel cell having a positive electrode layer, a negative electrode layer, and an ion exchange membrane interposed between the layers. The ion exchange membrane is a solution. The solution for the ion exchange membrane is applied while the solution for one of the positive and negative electrodes is undried.

Title: Method employed by a base station for transferring data
Inventor: AXNESS TIMOTHY A
IPC: H04B1/04
Filed: 2002-11-18
Granted: 2008-04-01
Abstract: A hybrid serial/parallel bus interface method for a base station. The method is employed for transferring data from a first node to a second node, the first node being the base station. The base station provides a data block, demultiplexes the data block into a plurality of nibbles, each nibble having a plurality of bits, and adds a start bit to each nibble. A  given state of at least a given one of the start bits initiates a transfer of data, thereby eliminating need for a separate clock line. For each nibble, the base station converts that nibble into serial data, provides a line and transfers the nibble serial data over the line. The second node converts the nibble serial data into parallel data to recover the nibble and combines the recovered nibbles into the data block.

Abstract: A sealing assembly for a pressurized fuel feed system for an internal combustion engine is disclosed. The seal assembly comprises providing a fuel conduit having a fluid flow passage therethrough for conveyance of a pressurized fuel-containing gas in a general fluid-flow direction with a first sealing surface disposed on the fuel conduit. A second sealing surface engages with the first sealing surface, such as to provide a fluid-tight connection preventing pressurized gas from leaving the fluid flow passage. The said first and second sealing surfaces are substantially perpendicular to the general fluid-flow direction. An o- ring is disposed between the first sealing surface and second sealing surface, the o-ring being compressed by the first and second sealing surfaces to form said fluid-tight connection. Preferably the o-ring is subjected to a squeeze of at least 40%, more preferably 50%, when the first and second sealing surfaces are coupled together. The sealing arrangement is most advantageously applied to throttle assemblies and the like, in particular for use with low-speed, gaseous fueled engines.

Abstract: A hybrid ARQ retransmission method in a communication system, wherein data packets being encoded with a forward error correction (FEC) technique prior to transmission, are retransmitted based on an automatic repeat request and subsequently soft-combined with previously received erroneous data packets either on a symbol-by-symbol or a bit-by-bit basis. The symbols of said erroneous data packets are modulated by employing a predetermined first signal constellation. The symbols of the retransmitted data packets are modulated by employing at least a predetermined second signal constellation. Each symbol bit has a mean bit reliability defined by the individual bit reliabilities over all symbols of the predetermined signal constellation. According to the invention, the predetermined first and the at least second signal constellation are selected such that the combined mean bit reliabilities for the respective bits of all transmissions are averaged out.
