Abstract: A dual-band helical antenna provides operation in two frequency bands. The dual-band helical antenna includes two single-band antennas (1304, 1308), each having a feed network (1804, 1808), a ground plane (412) opposite the feed network, and a set of one or more radiators (104A to 104D) extending from feed network. A tab (1504) extends from the feed network of one of the antennas which provides a feed for that antenna. The tab (1504) also provides a path for current to flow from the radiators of the second antenna along the axis of the second antenna to thereby increase the energy radiated in the directions perpendicular to the axis. The ground plane of one antenna is used as a shorting ring for the other antenna.

Abstract: An apparatus for liquefying a gas has a nozzle comprising a convergent nozzle portion, a nozzle throat and a divergent nozzle section; and in the case of supersonic flow a working section. Vanes or another mechanism for creating a swirl velocity are connected to the nozzle, to create a strong swirl velocity in gas fed to the nozzle. In the nozzle, the gas adiabatically expands, gas velocity increases and gas temperature drops, to promote the condensation of gas with formation of droplets. The gas then passes through a working section having a wall, whereby further condensation of at least a portion of the gas flow occurs and droplets of condensed gas grow. Centrifugal effects generated by the swirl velocity drive the droplets towards the wall of the working section. Condensed liquid gas droplets are separated from remaining gas in the gaseous state at least adjacent the wall of the working section. The method can be applied to liquefaction of a gas or to separation of one gas or several gases from a mixture of gases.

Title: No-spill drinking cup apparatus
Inventor: HAKIM NOURI E
IPC: B65D51/16
Filed: 1998-08-21
Granted: 2008-04-22
Abstract: A no-spill cup (22) and valve assembly (31) which provides a secure seal against accidental liquid flow from the cup spout. The act of sucking at the cup spout creates negative pressure or a partial vacuum against a valve (31) near the spout, causing the valve to invert which unblocks an opening in the valve. When the opening is unblocked, liquid can flow freely through the valve (31) and spout. When not in the use, the valve (31) sits in a resting, closed position, with the valve pressed against a center seal-off, sealing off the opening in the valve assembly. The cup (22) assembly further allows liquid flow to be regulated between regular or maximum flow and minimal flow levels or rates by rotating the position of the valve assembly in the cover of the cup.

Abstract: An injection molded plastic body has a lid joined by a living hinge. A rodent passageway extends within the body between two aligned holes. The hinge is perpendicular to the passageway, allowing the lid to be opened when the body is fixed adjacent a building wall. The interior of the body is divided by a raised wall which is broken into two segments by an opening to a blind passageway extending perpendicular to the passageway. Two rodent feeding areas are positioned adjacent the blind passageway. Bait blocks are positioned within each feeding area on protrusions which are received within axially extending central holes. The blocks are clamped between underlying rings and cooperating structure depending downwardly from the lid. Instead of bait, a mechanical trap may be positioned on two of three protrusions aligned along the blind passageway. The mechanical trap inter-fits with the protrusions to positively position the mechanical trap.

Title: Method and apparatus for increasing the sensitivity of a global positioning satellite receiver

Granted: 2005-06-14
Abstract: Method and apparatus providing enhanced sensitivity for GPS receivers (400, 500, 600, 700) by allowing coherent integration of a correlation over several code periods of a GPS signal in one embodiment, and by performing a time to frequency domain conversion to the output from a correlation processor (507) in a second embodiment. In the case in which coherent integration is performed over several code periods, advantage is taken of the fact that CDMA cellular telephone base stations transmit information that allows the receiver to determine GPS time before beginning a GPS signal acquisition process. The integration can be expanded to include code periods from more than one bit period, if the GPS receiver (400, 500, 600, 700) takes advantage of the fact that known bit patterns are transmitted at particular times within the transmission from a GPS satellite. If no base station is within range, then the output from a correlator (507) that integrates a correlation over one code period is used to generate values that are input to a discrete time domain to frequency domain transform processor (511). The output from the transform processor (511) will indicate the presence of a signal from a particular satellite and the offset between locally generated signal and the received GPS signal.

Title: Method and apparatus for reduction of fm interference for fm in-band on-channel digital audio broadcasting system
Inventor: BAIRD JEFFREY SCOTT
IPC: H04H20/82
Filed: 1999-10-28
Granted: 2010-02-02
Abstract: This invention provides a method for reducing FM interference in an in-band on-channel digital audio broadcasting system. The method includes the steps of receiving a composite signal including a signal of interest and an interfering signal and normalizing the composite signal to produce a normalized composite signal. The composite signal is then multiplied by the complex conjugate of the normalized composite signal to produce a real signal. Then the real signal is filtered and the resulting filtered signal is multiplied by the normalized composite signal to produce an output signal. The adverse effects of the interfering signal in the output signal are reduced with respect to the magnitude of the signal of interest reducing FM interference in an in-band on-channel digital audio broadcasting system, thereby making it easier to detect the signal of interest. The output signal and the composite can be blended in response to the power of the real and filtered signals. Radio receivers that utilize the above method are also included.
