Title: A compact side-fed dual reflector antenna system for providing adjacent, high gain antenna beams
Inventor: WILSON LOUIS C
IPC: H01Q25/00
Filed: 1999-12-29
Granted: 2002-09-17
Abstract: An antenna system comprising a feed array, a subreflector and a main reflector which are oriented to define a side-fed dual reflector antenna geometry. The feed array is comprised of a plurality of separate feeds which are aligned on a predetermined contour. Each feed array is coupled to a feed network which acts to combine the illumination beams of clusters of a preselected number of feeds to produce a plurality of composite illumination beams. Each composite illumination beam is directed to be incident upon a separate preselected location on the subreflector which directs the composite illumination beams towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth. Each antenna beam defines a separate coverage cell in the coverage area, wherein the position and orientation of the feeds, the subreflector and the main reflector provides antenna beams over a full Earth field of view coverage area where each antenna beam is approximately symmetrically shaped.

Granted: 2003-04-08
Abstract: An improved light responsive semiconductor switch with shorted load protection capable of successfully interrupting a load overcurrent. The switch is includes an output transistor which is triggered by a photovoltaic element to connect a load to a power source thereof, and an overcurrent sensor which provides an overcurrent signal upon seeing an overcurrent condition in the load. A shunt transistor is connected in series with a current limiting resistive element across the photovoltaic element to define a shunt path of flowing the current from the photovoltaic element through the current limiting resistive element away from the output transistor. A latch circuit is included to be energized by the photovoltaic element and to provide an interruption signal once the overcurrent signal is received and hold the interruption signal. The interruption signal turns on the shunt transistor so as to flow the current from the photovoltaic element through the shunt path, thereby turning off the output transistor for interruption of the overcurrent. The current limiting resistive element is connected in series with the shunt transistor to limit the current from the photovoltaic element when the shunt transistor is turned on, thereby providing a supply voltage from the photovoltaic element to the latch circuit. Thus, the latch circuit is enabled to keep providing the interruption signal for reliable interruption of the overcurrent.

Abstract: Méthodes, appareils et programmes informatiques pour l'auto-génération de nom de dispositif de communication en utilisant des processus exécutés par le dispositif. Les noms de dispositif sont ensuite utilisés pour identifier les dispositifs dans le cadre de communications réseau. Ceci permet de se dispenser du processus inhérent d'attribution de nom de dispositif unique par une autorité de dénomination centrale. L'unicité des noms de dispositif est obtenue au moyen d'une convention de dénomination basée sur des classes dans laquelle des noms de classes sont associés à des types de dispositifs et des identificateurs uniques de dispositifs sont attribués à des dispositifs au sein d'une classe. Le format des identificateurs de dispositifs d'une classe peut être très différent de celui des identificateurs de dispositifs d'autres classes. Des processus sont utilisés pour l'interprétation des différents formats d'identificateurs de dispositifs afin d'identifier les dispositifs individuels.

Inventor: POPP ROGER C
IPC: F02M61/08

Granted: 2005-08-23
Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg.300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions.  The fuel injector is powered by hydraulic signals from an electrohydraulic valve.  The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. The cartridge comprises an activator body and a valve body secured together, and the valve body has a gas valve slidable therein. The stroke of the valve is adjustable by controlling the size of shims in the valve body assembly, thereby providing a universal valve cartridge that can be easily adapted to differing fueling requirements for models and sizes of engines. The valve body includes a spring chamber between upper and lower valve guides. The valve body also includes cross-holes to allow cool gaseous fuel to successively pulsate into and out of the spring chamber and thereby cool the exposed portion of the valve between guides, preventing heating of the dynamic gas seal located in the upper guide. An unsealed small clearance between the actuating piston and its bore in the actuator body allows controlled leakage of oil. The leakage of oil lubricates metal to metal contact between the upper guide and the valve and lubricates the dynamic gas seal. Gaseous fuel leakage into the leaked oil is tolerated and any combined oil/gaseous fuel is removed to an external location for separation. Spring washers are used to urge the valve assembly insert against a metal O-ring supported by the outer cartridge body.

Title: Method and apparatus for increasing the rating of a transformer
Inventor: OWEN DONALD W
IPC: H01F27/28
Filed: 2001-05-08
Granted: 2014-07-22
Abstract: The voltage class rating of a transformer ie increased by increasing the rating of an off the shelf molded transformer bushing. Specifically, the voltage class rating is increased by increasing the distance from the non-insulated portion of a conductor of a transformer bushing and the transformer wall. A conductive extension is connected to the conductor of the bushing. Insulating material in the form of mastic and heat shrink tubing is applied to the external portion of the conductor and the extension. When the modified transformer bushing is installed into a transformer, an internal end of the conductor is made to extend below the surface of the oil in the transformer. The level of the oil also covers an internal insulating shoulder of the bushing. The insulating values of the mastic and heat shrink tubing and the insulating value of the conductor immersed in oil combine to increase the voltage class rating of the off the shelf molded transformer bushing and thereby the transformer, with a nominal increase in costs.

Title: Adaptive tuning device and method for a wireless communication device
Inventor: CAMPBELL COLIN K
IPC: H03H7/38
Filed: 2001-05-30
Granted: 2005-08-09
Abstract: An adaptive tuning method for a wireless communication device determines the impedance of a matching circuit relative to an impedance to be matched and adjusts the impedance of the matching circuit accordingly. A passive surface acoustic wave (SAW) device includes multiple terminated interdigital transducers (IDTs) which generate reflected SAWs when excited by incident SAWs, each reflected SAW having magnitude and phase characteristics dependent upon the particular IDT termination. According to the invention, the IDT terminations include the impedance matching circuit and the impedance to be matched. Input IDTs in the SAW device are excited with electrical signals, which are converted to generate the incident SAWs. The resultant reflected SAWs are converted by output IDTs into output electrical signal signals which can then be analyzed to determine magnitude and phase differences between the output electrical signal signals and generate an impedance matching circuit control signal based thereon.

Abstract: A high-density folded bitline memory array architecture is disclosed. High memory cell packing density is achieved by dividing polysilicon wordlines into short individual segments in the folded bitline scheme. Each wordline segment forms the gate of one or two DRAM memory cell transistors, and each segment is connected to a metal wordline, or conductor having low resistivity. By eliminating spaces between the memory cells due to passing wordlines, a cell arrangement and density similar to open bitline schemes is achieved. Further packing is obtained by arranging two columns of memory cells parallel to each bitline, each column offset with the other by a predetermined pitch. Therefore, by increasing the number of memory cells connected to each complementary bitline pair, each bitline pair can be cut in half and connected to its own bitline sense amplifier to reduce the bitline capacitance. Hence the memory cell architecture of the present invention occupies less area, and operates with faster speed than memory cell architectures of the prior art.
