Granted: 1999-01-19
Abstract: A refueling check valve assembly (10) which provides for rapid, efficient, and safe refueling of compressed natural gas powered vehicles is provided and includes a receptacle (12) adapted to mate with a fuel supply nozzle and a valve body (14) having first and second gas flow passages (36, 38) therethrough.  The respective first ends of the first and second gas flow passages communicate with the receptacle, while the respective second ends of the first and second gas flow passages are adapted to communicate with a fuel storage vessel, typically through a fuel supply line.  A check valve (40) is positioned in the first gas flow passage of the valve body and is normally biased into a closed position to prevent the flow of gas through the first gas flow passage.  The check valve opens in response to a flow of fuel under pressure, permitting the flow of gas to the fuel storage vessel.  A by-pass (60) valve is also provided in the second gas flow passage in the valve body for depressurizing the fuel system prior to servicing.

Title: Exhaust hood
Inventor: BOUDREAULT JEAN-PIERRE
IPC: F24C15/20
Filed: 1995-11-01
Granted: 2001-05-08
Abstract: Along the path of the cooking fumes of an exhaust hood where the fumes move with swirling motion, forwardly adjustable blades are disposed between a retracted and an extended position to accentuate or decrease the intensity of the swirling path end of the centrifugal force applied to the particles to be removed, depending on the volume and the flow rate of the cooking fumes which ascend through the hood. This blade arrangement also ensures a constant static pressure inside the hood for a maximum efficiency of extraction.

Title: Determining fluid properties from pressure, volume and temperature measurements made by electric wireline formation testing tools
Inventor: YESUDAS MICHAEL
IPC: E21B49/00
Filed: 1996-06-12
Granted: 1998-11-03
Abstract: A method of determining an amount of dissolved gas in a fluid sample is disclosed. The method includes hydraulically confining and expanding the sample while measuring pressure and volume. A first volume and pressure are determined at which the rate of change in pressure with respect to volume deviates from a linear relationship. A second volume and pressure at which continued expansion of the fluid causes substantially no change in pressure is determined The first pressure and volume are extrapolated by the linear relationship to intersect an extrapolation from the second volume and pressure at no change in pressure, thereby determining a bubble point comprising a bubble point pressure and a bubble point volume. A third pressure corresponding to measured pressure of the fluid sample at the bubble point volume is determined. An extrapolated sample volume is determined at the third pressure byextrapolating the linear relationship from the bubble point to a sample volume along the linear relationship corresponding to the third pressure. A volume of gas dissolved in the fluid sample is determined by linearly scaling a difference between the bubble point volume and the extrapolated sample volume with respect to a difference between the second volume and the bubble point volume. In a preferred embodiment of the invention, the sample is withdrawn into a sample chamber in an electric wireline formation test tool having a means for measuring pressure and volume of the sample chamber.

Abstract: An IC card reader that can output data in an audio form. The IC card reader includes a small portable case in which an IC card can be inserted. A microcontroller powered by a battery within the case reads the stored data from the IC card and encodes the read data into a series of voice commands. A voice synthesizer circuit produce a synthetic speech signal from the encoded data. An amplifier within the case is connected to the voice synthesizer circuit for amplifying the synthetic speech signal. A speaker also internal to the case is responsive to the synthetic signal for outputting an audio signal corresponding to the stored data through small holes in the front face the case. A membrane switch within the case can be closed using a push button on thefront face of the case to electrically connect the microcontroller to the card. Thus, in use of the IC card reader, when the button is depressed to close the switch, themicrocontroller is caused to interrogate the card so that the data stored on the card is read into the microcontroller. The microcomputer produces a synthetic speech signal that is amplified by the amplifier and output by the speaker as synthetic speech which can be heard by the user by holding the card reader with the speaker against the user's ear.

Title: Virtual authentication network for secure processors

Granted: 2000-06-13
Abstract: The integrity of a group of secure processing elements (10, 20, 30, 40, 50, 60, 70, 80) in a communication system is ensured with a validation scheme.  Member elements (10, 20, 30, 40, 50, 60, 70, 80) are checked by adjacent members to determine whether a member has been tampered with or operatively removed from a group.  If a member is found to be untrustworthy, propagation of group characteristic information to that member will be halted.  The group characteristic information defines the group, and is required by each group member in order to function.  The untrustworthy member is therefore effectively exiled from the group.  An efficient network topology minimizes inter-member message traffic while maintaining group robustness.

Filed: 1996-03-01
Granted: 2007-01-09
Abstract: A system for monitoring and the adjustment of control unit parameter settings of vehicle electronic control units (44, 45).   The monitoring system may be implemented in a vehicle (12, 14) in which are incorporated one or more electronic control units (44, 45) for regulating one or more operational parameters of the vehicle (12, 14) in accordance with corresponding control unit parameter settings. In an exemplary implementation the vehicle (12, 14) is equipped with a mobile communications terminal, MCT (38), which receives from a base station (18) a list of operational parameters to be monitored. Each of the electronic control units (44, 45), as well as a memory unit (62), are connected to an internal data link (40) of the vehicle. When a parameter value within the memory unit (62) corresponding to a given electronic control unit (44, 45) is changed, a message is provided to the base station (18) specifying the value currently registered by the particular electronic control unit (44, 45). The currently registered value is then compared to an expected parameter value, and an error message is generated if disagreement exists therebetween. The system also allows vehicle electronic control unit parameter settings to be adjusted from a remote location such as a base station (18).
