Abstract: Fuel cells (38) have water passageways (67; 78, 85; 78a, 85a) that provide water through reactant gas flow field plates (74, 81) to cool the fuel cell. The water passageways may be vented to atmosphere (99), by a porous plug (69), or pumped (89, 146) with or without removing any water from the passageways. A condenser (59, 124) receives reactant air exhaust, may have a contiguous reservoir (64, 128), may be vertical, (a vehicle radiator, FIG. 2), may be horizontal, contiguous with the top of the fuel cell stack (37, FIG. 5), or below (124) the fuel cell stack (120). The passageways may be grooves (76, 77; 83, 84) or may comprise a plane of porous hydrophilic material (78a, 85a) contiguous with substantially the entire surface of one or both of the reactant gas flow field plates. Air flow in the condenser may be controlled by shutters (155). The condenser may be a heat exchanger (59a) having freeze-proof liquid flowing through a coil (161) thereof, the amount being controlled by a valve (166).

Abstract: Fuel cells (38) have minute water passageways (67) that provide water through one or both reactant gas flow field plates (74, 82) of each fuel cell, whereby the fuel cell is cooled evaporatively. The water passageways (67; 78, 85; 78a, 85a) may be vented by a porous plug (69), or by a microvacuum pump (89) that does not pump any water from the passageways, or simply vented (99) to atmosphere. A condenser (59) may have a contiguous reservoir (64); the condenser (59) may be vertical, such as a vehicle radiator (FIG. 1), or may be horizontal, contiguous with the top of the fuel cell stack (37, FIG. 5). The passageways may be grooves (76, 77; 83, 84) in the reactant gas flow plates (75, 81) or the passageways may comprise a plane of porous hydrophilic material (78a, 85a) contiguous with substantially the entire surface of one or both of the reactant gas flow field plates.

Abstract: A vehicle back-up safety system comprising a sensing system for detecting the presence of an obstruction within a prescribed area behind the vehicle while a user is driving in reverse. In response to a signal from the sensing system signifying the presence of a an obstruction, a control means activates a fluid distribution system which draws brake fluid from the master brake cylinder and into the vehicle's brake line system, thereby activating the vehicle's brakes.

Abstract: An elevatable wheelchair having a hydraulic system for elevating and lowering the wheelchair and a drive gear arrangement for motivating the wheelchair while the wheelchair is in an elevated position. The hydraulic system comprises four hydraulic legs, each corresponding to and coupled to one of a pair of front wheels or to one of a pair of auxiliary rear wheels. When hydraulic fluid is introduced to the four hydraulic legs, the hydraulic legs begin to extend, thereby elevating the wheelchair. The hydraulic system also comprises a pair of flow equalizers to ensure a uniform flow of hydraulic fluid to each hydraulic leg, thereby enabling each hydraulic leg to extend at the same rate. The elevatable wheelchair also comprises a drive gear arrangement which coacts with the main wheels of the wheelchair in order to transfer motion to the auxiliary rear wheels, thereby enabling the wheelchair user to motivate the wheelchair while in the elevated position by engaging the hand rails on the main wheels.

Abstract: A "Barometer" Neuron enhances stability in a Neural Network System that, when used as a track-while-scan system, assigns sensor plots to predicted track positions in a plot/track association situation. The "Barometer" Neuron functions as a bench-mark or reference system node that equates a superimposed plot and track to a zero distance as a "perfect" pairing of plot and track which has a measured/desired level of inhibition. The "Barometer" Neuron responds to the System inputs, compares these inputs against the level of inhibition of the "perfect" pair, and generates a supplied excitation or inhibition output signal to the System which adjusts the System to a desired value at or near 1.0; this the reference level of inhibition of the "perfect" pair.

Abstract: A vector neural network (VNN) of interconnected neurons is provided in transition mappings of potential targets wherein the threshold (energy) of a single frame does not provide adequate information (energy) to declare a target position. The VNN enhances the signal-to-noise ratio (SNR) by integrating target energy over multiple frames including the steps of postulating massive numbers of target tracks (the hypotheses), propagating these target tracks over multiple frames, and accommodating different velocity targets by pixel quantization. The VNN then defers thresholding to subsequent target stages when higher SNR's are prevalent so that the loss of target information is minimized, and the VNN can declare both target location and velocity. The VNN can further include target maneuver detection by a process of energy balancing hypotheses.
