Abstract: In a remote unit receiver capable of demodulating a plurality of signal instances corresponding to a singe remote unit transmitted signal, a first instance of a signal is demodulated to produce a first set of energy values corresponding to a set of possible data values of the signal. A second instance of the signal is demodulated to produce a second set of energy values corresponding to the set of possible data values. The first and the second sets of energy values are then combined to determine a combined set of energy values. A first estimate of a most likely transmitted data value is determined based upon the combined set of energy values.

Abstract: The present invention discloses a process to add a thin, active coating to all of the passageways, ports, and flow field channels of an assembled fuel cell or fuel cell stack. The coating substance may include, alone or in combination, ionomers (such as Nafion®), wicking fibers, catalyst, sealants, and water absorbents. The coating provides, alone or in combination, water management, electrochemistry enhancements, porosity control, and leak-seal functions. The invention is carried out in five steps. In the first step a coating fluid is prepared containing the desired substance(s) and a diluting carrier fluid such as alcohol. In the second step, the coating fluid is pumped or vacuum drawn into the cell/stack via an existing external connections (inlet/outlet ports). In the third step, the surplus coating fluid is removed by purging and/or vacuuming, leaving only a thin, coating or deposit behind. In the fourth step vacuuming and/or heating and/or spinning of the cell/stack is used to evaporate the carrier fluid. In the fifth step the stack is heated to a temperature that sets, inverts micelle structures, or otherwise makes the coating permanent. The process may be repeated to thicken the deposited layer or to add substances successively.

Abstract: A flexible metal hose formed by a helically wound metal having an "S" shaped cross-section.  The strip is provided with projections and recessions, with projections and recessions of adjoining convolutions meshed, enabling hose flexure without unwrapping.  First and second resiliently engaged sealing surfaces extend helically along the hose to block leakage via the projections and recessions. In one embodiment the sealing surfaces are formed on a lip of one convolution and a body portion of the adjoining convolution. A second embodiment is a "smooth bore" hose having a first helical strip, constructed as described, and a second helical strip with first and second smoothly cylindrical axially spaced radially inner and outer regions. One region forms the smooth bore and the other is resiliently engaged between the radially outer lip of the first strip and the radially outer first strip body portion of the adjoining convolution to form the seal.

The fibers (typically at least 85 %) have a length between 5-100 mm, preferably 7-50 mm, substantially the same as the length of the fiber bundle they are in. The fibers are preferably held in the bundles by substantially non-water soluble sizing, such as epoxy resin or PVOH. The fibers in the bundles typically have diameters of approximately 7-500 microns, preferably about 7-35 microns. The bundles may comprise at least 10 % reinforcing fibers, such as glass, aramid or acrylic.
