Inventor: OBERMANN MARK
IPC: H03F1/00
Filed: 1996-08-05
Abstract: An amplifier circuit (100) for use in a radio frequency system. The circuit is comprised of a first amplifier (22) having a first input (20) receiving a first signal (16) and a first output (24). A first coupler (18) samples the first input (20) of the first amplifier (22) and a second coupler (26) samples the first output (24) of the first amplifier (22). A third coupler (36) then compares an output of the second coupler (28) and an output of the first coupler (34), producing an error signal (38) which is substantially indicative of the difference between the first input (20) and the first output (24). A fourth coupler (44) combines the error signal (38) with a second signal (48) to produce a composite signal (50), the second signal (48) at least partially correlated with the first signal (16) received by the first input (20) of the first amplifier. A second amplifier (52) is responsive to the composite signal (50) and produces a second output (54).

Title: Method and apparatus for determining the location of an occupant of a vehicle
Inventor: FREDRICKS RONALD J
IPC: G01S11/04
Filed: 1997-07-15
Abstract: A method and apparatus for use in locating a vehicle driver, passenger or object in the vehicle for controlling vehicle systems including the positioning of vehicle sideview mirrors in relation to the driver's eyes to maximize the view of traffic on either side of the vehicle or the characteristics of vehicle airbag deployment. The location of a driver's or passenger's eyes or the location of an infant's seat is derived from the adjustment by the driver (or passenger, if capable of doing so) of adjustable light beam(s) emanating from light source(s) or illuminated indicia, until it (or they) intersect the driver's or passenger's eyes or illuminate a target, e.g. a child or an infant's seat, in the front passenger's seat. From the angles of adjustment of the light beam(s) and other known coordinates of the vehicle, the location of the driver's or passenger's eyes or the target may be computationally derived as a set of Cartesian coordinates. The determined eye location of the driver may be used together with the known mounting locations of the driver's and passenger's sideview mirror assemblies to derive exterior sideview mirror pitch and azimuth adjustment signal sets correlated to the vehicle blind spots. The adjustment signals are applied to servo motors operating in a feedback control loop to correct the actual driver's side and passenger's side sideview mirror pitch and azimuth settings to properly reflect images of the driver's side and passenger's side vehicle blind spots to the driver's eyes. The determined eye locations of the driver and passenger or the target location of the infant's seat may be also or alternative employed in the control of the airbag deployment system and in other vehicle safety and comfort systems.  The relative fore-aft distance away from the airbag and the height of the person or target can be computed, and airbag deployment force and/or duration adjusted to compensate for deviation from the standard height and fore-aft distance.

Abstract: A process and system which improves the capacity and efficiency of a power plant. An LNG supply system (12) fuels the plant. Gasified LNG in a combustor (30) mixes with the air from an air compressor (28) to provide the hot combustion gas for a gas turbine (32). The expanding LNG is used to chill (16) a heat exchange fluid, e.g. water, which heat exchange fluid cools (24) and densifies the intake air for the air compressor (28). Subsequently, the heat exchange fluid is used in another heat exchange step (46) and is then re-chilled and recycled to cool and densify the intake air.

Filed: 1998-04-06
Abstract: A flexible, gussetted package having an interior for holding some particulate material product, under vacuum, and which includes a mouth to be opened to provide access to the contents of the package. The package is formed of a flexible material and includes a front panel, a rear panel, and a pair of opposed side gussets and a pressure equalizing valve. The valve is arranged to operate in a first mode of operation wherein any gasses within the package are allowed to vent to the exterior of the package, while the ambient atmosphere is precluded from entering into the interior of the package. The valve also operates in a second, transitory, mode wherein it allows a small amount of the ambient atmosphere to gain ingress into the interior so that the package's walls give a smooth appearance. The valve then enters into its third mode of operation wherein it isolates the interior of the package from the exterior.
