Abstract: A portable electricity generation device comprises a plurality of fuel cells, each fuel cell having an anode end with a catalyst facilitating the separation of hydrogen atoms into electrons and protons, a cathode end facilitating the combination of the electrons and protons into water molecules in the presence of oxygen, and a current bearing portion providing a current path for the electrons to traverse. The electricity generation device also includes a fuel storage container for storing a supply of hydrogen and delivering the supply of hydrogen to an anode end of the plurality of fuel cells so as to initiate a flow of the electrons through the current bearing portion. In addition, the portable electricity generation device includes an air moving device configured to direct atmospheric air toward a cathode end of the plurality of fuel cells, wherein the air moving device is positioned to convectively cool the plurality of fuel cells as it supplies atmospheric air to the cathode end.

Abstract: There are many inventions described and illustrated herein. In one aspect, the present invention is directed to a portable fuel cell power and management system (for example, hydrogen and/or methanol based systems), components and/or elements thereof, as well as techniques for controlling and/or operating such systems. The fuel cell power management system (and method of controlling and/or operating same) actively monitors, manages and/or controls one or more operating parameter(s) of the fuel cell system. For example, the system monitors, manages and/or controls the consumption and/or the rate of consumption of fuel by the system, and in response thereto, may provide and/or alert the user to amount of fuel remaining, consumed, the rate of consumption and/or the time (or estimation thereof) remaining until all of the fuel is spent. In this way, the user may schedule or plan accordingly.

Abstract: A hot water recirculation system includes a source of hot water, a fixture, a fluid circuit, a fluid pump, and an electrical circuit sensor. The fixture is remote from the source of hot water and is configured to dispense hot water. The fluid circuit extends from the source to the fixture for delivering hot water to the fixture. The fluid circuit returns to the source for recirculating hot water in the fluid circuit back to the source for reheating. The fluid pump is configured for recirculating hot water through the fluid circuit. The electrical circuit sensor is configured to detect operation of an electrical circuit proximate the fixture and associated with a user operating the fixture. The electrical circuit sensor is further configured to initiate operation of the fluid pump responsive to detected operation of the electrical circuit to initiate hot water recirculation. A method is also provided.

Abstract: A display system and method of displaying data relating to a generator control unit for an aircraft having a first memory of a first type and a second memory of a second type. The first memory contains display data relating to a generator control unit for an aircraft and a plurality of file markers interspersed among the display data, with each of the file markers occupying a respective position in the first memory. The first memory is searched to locate the positions of the file markers. Those positions are stored in the second memory, which is preferably a random-access semiconductor memory. The display data in the first memory is displayed by retrieving a portion of the display data from the first memory based upon the positions stored in the second memory.

Abstract: Apparatus and method for converting image data of an image matrix to an image matrix having a different number of matrix points. Each new image pel has a gray scale determined by considering its position with respect to the nearest neighbors of an original image pel. A look up table is provided having a plurality of planes, each plane including a plurality of storage elements arranged in columns and rows. The storage elements contain the gray scale level of a new image pel. The look up table plane represents the gray scale levels for a plurality of positions within the neighborhood. The planes are addressed by the gray scale levels of the pels comprising the neighborhood, and the storage elements within a plane are addressed by the position of the new pel with respect to the neighbors.

Abstract: Operation of an AC plasma display panel requires the three control operations of write, erase, and sustain. Sustain, write and erase signals are stored in a plurality of sections in a storage device and the sections are selectively accessed according to the specific operation to be provided to the plasma panel display. Switching between the sections in the storage device is accomplished without signal discontinuity in the sustain, write, and erase signals used to drive the illuminable cells. The sustain operation is recycled during those periods when no write or erase operation is being done.

Abstract: A pressure relief panel for an aircraft powerplant comprises a carbon disc designed to fragment when the pressure difference across it reaches a pre-determined level. The panel is designed to totally enclose the disc and has two walls one of which is dished to form the enclosure the other of which is shaped to form a smooth continuation of the powerplant outer surface. The walls are apertured to expose the disc to both ambient pressure and the pressure in the interior of the powerplant wall, the apertures having a total area sufficient to allow passage therethrough of the flow from any of the fluid-carrying pipes within the wall should a leak or breakage occur, but the individual apertures each having an area sufficiently small to prevent escape from the enclosure of potentially dangerous pieces of the disc.

Abstract: A drinking straw formed with a flexible corrugated intermediate section is fixed to a flat flexible tab adjacent the intermediate section, which tab may be bonded between the sealing flaps of a paper container with the straw held inside the container. Alternatively, the tab may be fixed between a seal disc and a closure cap of a bottle or can so that the straw may be suspended, in folded array inside of the bottle or can prior to use.
