Abstract: A fuel cell is disclosed which is formed on a semiconductor wafer by etching channel in the wafer and forming a proton exchange membrane PEM barrier in the etched channel. The barrier divides the channel into two. A hydrogen fuel is admitted into one of the divided channels and an oxidant into the other reacts with a catalyst formed on an anode electrode at the hydrogen side of the channel to release hydrogen ions (protons) which are absorbed into the PEM. The protons migrate through the PEM and recombine with return hydrogen electrons on a cathode electrode on the oxygen side of the PEM and the oxygen to form water.

Abstract: The present invention provides a cursor control device for use in three dimensional space. The cursor control device is based on point and click technology such that a user points a remote member of the cursor control device to a television assembly and depresses appropriate keys for corresponding functions. In particular, a mouse key on the remote member enables control of cursor movement functioning of a cursor displayed through the television assembly. A base unit portion of the present invention device is coupled to or interfaced with the television assembly. The base unit provides an ultrasound source for use of ultrasound by the remote member for determining positioning angular orientation of the remote member in three dimensional space. The base unit includes an infrared receiver for receiving infrared signals generated by an infrared transmitter at the remote member. Mouse commands and other commands from the remote member are communicated through infrared signals to the base unit.

Abstract: To provide a pair of shoes responsive to the relative forces applied to a wearer's feet, at least one force sensor is provided in each of a left and right shoe. The sensor detects pressures which are then converted from a form provided by the sensor into a digital form which may be processed on by a microprocessor. The processor then executes any one of a number of force analysis programs and outputs, in a preferred form, a force model comprising attack, decay, sustain and release information. Each shoe then transmits coded information representing the sensed force profile to a central receiving device which may be located in a watch-like receiver worn on the wearer's wrist. The receiving device has the ability to pick up and discern signals transmitted by each left and right shoe and also from a number of auxiliary transmitters. Control of the display is made through the use of selector switches which also appear on the user interface.

Abstract: An apparatus for disinfecting water in a water cooler holding tank by using an ultra-violet radiation to eliminate biological growth. The apparatus includes a bottle positioning collar that adapts to the base unit of a standard water cooler adjacent where the neck of an inverted water bottle is supported by the base unit. Incorporated within the collar is an ultra-violet lamp assembly, which under control of an electrical supply unit, periodically exposes the water standing in the holding tank to disinfecting ultra-violet radiation. The collar may include a transparent window which may be easily accessed for cleaning when the water bottle has been removed.

Abstract: Device and method for preparation of a condom by a user. The device defines a circular surface adapted to receive the annular ring of a condom in retaining or sealing relationship and gas inflation source is provided for producing a gas flow into the condom. By producing a pressure level to cause a detectable loss of air if the membrane has porosity in excess of a predetermined maximum degree the user can effectively test the condom for leaks. By associating the gas inflation sources with a composition selected to reside in the condom during use and effective against sperm or disease organisms, the user may achieve an improved degree of protection.

Abstract: A device and method for testing the integrity of a vaginal diaphragm having an annular ring about a membrane desired to be nonporous consists of a base member defining a surface for engaging the ring in sealing relationship and defines, with the membrane, a pressure chamber, a clamp for clamping the ring in sealing relationship upon the surface, apparatus for creating an inflating pressure condition in the chamber of a level predetermined to cause loss of air from the chamber through the membrane if the membrane has in excess of predetermined maximum degree of porosity, and an indicator of loss of air from within the chamber. Preferably the clamp is defined by a cover, and the device is in the form of a protective carrying case for the diaphragm.

Abstract: A computer system for processing analog and digital data input signals from many sources and producing analog and digital data output control signals includes a plurality of digital processing devices for processing the input data, a Processor Bus that interconnects the processing devices for relatively very high speed data transmission between the processing devices a plurality of analog and digital input and output data converter modules, a Converter Bus that interfaces the converter modules and a controller device that couples the Processor Bus and the Converter Bus together and controls the flow of signals therebetween, whereby analog and digital input data received at a range of data rates from relatively low to relatively high rates by input converter modules is transmitted on the Converter Bus to the Processor Bus, via the controller device, in digital format and is processed in the digital format at relatively very high data rates by one or more of the processing devices and digital output data from t
