  • Patent number: 8776493
    Abstract: A prime mover uses detonation chambers to provide rotary power through a center hub. The center hub has a center shaft able to rotate and mounted to the center hub, and rotating arms are mounted to the center shaft. A detonation chamber is mounted to each rotating arm at a distance from the center hub which establishes a force moment about the center hub. Fuel passages connect an external fuel source, such as hydrogen and oxygen, with the detonation chambers to deliver fuel to the detonation chambers. Fuel delivered to the detonation chambers is ignited to establish a reaction force which is transferred through the rotating arms and the center hub. The rotating force is used to drive a generator.

  • Patent number: 7027009
    Abstract: A method and apparatus for communicating simultaneously at the same frequencies includes two or more conductor-backed, spiral antennas that have been shown to exhibit linear polarization. To permit simultaneous transmission on the same frequencies, two of the linearly polarize, conductor-backed spiral antennas can be spaced vertically and be oriented so that the feed points of one antenna are orthogonal to the feed points of the second antenna. Since the specifically designed spiral antennas will be both transmitting or both receiving at orthogonally arranged polarizations, the antennas will not interfere with each other, even though communication is upon substantially the same frequencies.

  • Patent number: 6972725
    Abstract: A multi-antenna garment comprising a first and second antenna incorporated into an electrically nonconductive garment, with tubular composites to improve gain and mitigate radiation hazard. The first antenna includes first and second RF elements attached to a first garment so that a gap exists between them, where the RF elements each form a band when the garment is worn by a wearer. The second antenna includes third, fourth, fifth, and sixth RF elements attached to a second garment worn over the first garment. RF feeds are electrically connected to the first, third, and fifth RF elements. Ground feeds are electrically connected to the second, fourth, and sixth RF elements. Insulating material disposed over gaps between the first and second, the third and fourth, and the fifth and sixth RF elements and in pockets in the regions of the RF feeds limits the wearer's exposure to electromagnetic field to acceptable levels.

  • Patent number: 6788262
    Abstract: An ultra-broadband antenna incorporated into an electrically nonconductive garment, with radiation absorber material to mitigate radiation hazard. The antenna includes first and second RF elements attached to the garment so that a gap exists between them, where the RF elements each form a band when the garment is worn by a wearer. RF and ground feeds are electrically connected to the first and second RF elements, respectively. A shorting strap electrically connected between the first and second RF elements on the anterior side of the garment generally opposite the feeds helps match the antenna impedance to an external signal source. Radiation absorber material disposed over the gap between the first and second RF elements and in a pocket in the region of the RF feed limits the wearer's exposure to electromagnetic field to acceptable levels.

  • Patent number: 6621457
    Abstract: An antenna includes a liner shaped to fit over a helmet; a first RF element attached to the liner; a second RF element attached to the liner so that the first and second RF elements are separated by a gap; an RF feed electrically connected to the first RF element for providing RF energy to the first RF element; a ground feed electrically connected to the second RF element; a first shorting strap that is electrically connected to the first and second elements opposite from the RF feed; and a second shorting strap electrically connected to the first and second RF elements between the first shorting strap and the RF feed. The shorting straps are used to generally match the impedance of the antenna to an electrical device such as a transmitter, receiver, or transceiver. A matching circuit may be connected in series between the first RF element and the RF feed to further refine matching the antenna impedance to the electrical device.

  • Patent number: 6448941
    Abstract: A method for communicating with a decreased probability of detection by an unintended listening party uses frequency hopping and two substantially identical linearly polarized antennas whose polarization vector is synchronized to frequency. Synchronization of polarization with frequency is accomplished through specifically designed conductor-backed spiral antennas. For these conductor-backed spiral antennas, a change in frequency is synchronized to a change in the polarization vector of the communication signal. Since the receiving station will be programmed to alter its reception frequencies in accordance with those being transmitted, the second spiral antenna will automatically change its polarization upon making these frequency changes. A rapid change of polarization increases the difficulty in detecting and intercepting the communication by parties for whom the message was not intended.

  • Patent number: 6342866
    Abstract: A wideband antenna system comprises a stack of m antennas, where m is a positive integer, and m≧2. Each antenna includes: a) an electrically insulating substrate; b) opposed first and second radio frequency elements mounted to the substrate; c) a ground feed electrically connected to the first radio frequency element; d) an excitation feed electrically connected to the second radio frequency element; and e) a ground plane mounted to the substrate of the mth antenna. The radio frequency elements of each antenna collectively have a unique total area and are mounted to the electrically insulating substrate. The radio frequency elements of the ith antenna provide a ground plane for the kth antenna, where i and k are positive integers, 1≦k≦(i−1), and 2≦i≦m. The total area of the first and second radio frequency elements of the ith antenna is greater than the total area of the first and second radio frequency elements of the kth antenna.

  • Patent number: 5713515
    Abstract: In a fluid heating apparatus having a fluid tank, a combustion chamber communicating with the fluid tank for heat exchange, and a combustible fluid delivery system coupled to the combustion chamber, a plurality of valves are individually configured in either an off-state or an on-state for delivering combustible fluid to the combustion chamber. Depending on the configuration of the multiple valves, the rate at which combustible fluid is supplied to the combustion chamber may be varied in response to a heat demand signal. Individual valve signals are generated for each of the multiple valves in response to the heat demand signal to place the multiple valves in a configuration to supply combustible fluid at predetermined rates. The demand signal is calculated in response to reading temperature at an inlet temperature probe and an outlet temperature probe, wherein the outlet temperature probe is located nearer a fluid outlet from the fluid tank than is the inlet temperature probe.

  • Patent number: 5437249
    Abstract: A water heater is shown having a closed tank with an opening for receiving a combustion chamber, the interior of the tank normally containing water under pressure. A combustion chamber is located within the tank interior and includes a body portion having an open end adjacent the tank opening into which combustible fuel is introduced and ignited in the presence of air to create products of combustion. A flue collector is mounted on the exterior of the closed tank and has an annular chamber surrounding a flue opening for receiving the products of combustion for exhaustion to the atmosphere. An outer wall portion closes one end of the flue opening to provide a closed compartment within the collector which can be pressurized by an external blower. An inner wall portion of the collector has an opening which communicates with the combustion chamber.

  • Patent number: 5400962
    Abstract: A system and method for controlling operation of a water heater provides generating a heating demand signal which a minimum level corresponds to a required heat input for maintaining water temperature in the water tank in case of no exogenous demand for water. Responsive to the heating demand signal, air flow from the forced draft blower and flow of combustible fluid from the combustible fluid delivery system are varied to produce combustion product over a minimum 15 to 1 ratio. This allows water heating to be varied to meet maximum expected exogenous demand or to maintain water temperature with no exogenous demand.
