Title: Mechanical kickdown for electronic throttle control pedal assembly
Inventor: KALSI AVTAR S
IPC: B60K26/02
Filed: 2000-07-25
Abstract: An accelerator pedal assembly (12) for electronically controlling a vehicle engine throttle includes a housing (18), a pedal arm (16) pivotally supported with respect to the housing (18), and a pedal pad (14) connected to a lower end (20) of the pedal arm (16). The pedal arm (16) is pivotable between an idle position and a maximum applied position as a pedal force is applied to the pedal pad (14).  Under certain conditions, the accelerator pedal arm (16) can be pivoted to a position that causes the automatic transmission (40) to kickdown by changing to a next lower gear. Under these conditions a feel is imparted to the driver's foot indicating that a downshift has occurred. To simulate this feel in a drive-by-wire application, the pedal arm (16) presents a cam surface (48) for interacting with a spring (50) that has a first end (52) seated within the housing (18) and a movable second end (54) for bias engagement with the pedal arm (16). The spring (50) includes a roller (60) mounted on the second end (54) that is forced into contact with a lobe (74) on the cam surface (48) when the pedal arm (16) is pivoted from a first operable position to a pre-determined kickdown position. As the roller (60) engages the lobe (74), the pedal force required to further pivot the pedal arm (16) is increased imparting a kickdown feel to the driver via the pedal pad (14).

Title: Spring applied parking brake assembly having a manual quick release feature
Inventor: LEWIS ROGER V
IPC: F16D65/22
Filed: 2001-01-22
Abstract: A spring applied parking brake assembly for a railroad vehicle braking system is provided for an automatic application of the parking brake in the absence of an air source. The spring applied parking brake assembly comprises a cylindrical casing containing a piston assembly. The piston assembly is mounted for longitudinal movement within the casing upon the application and/or removal of pneumatic pressure to the piston assembly. The piston assembly is associated with a force transfer lever of the braking system so as to apply a force to this force transfer lever upon longitudinal movement of the piston assembly. At least one spring member is provided within the cylindrical casing. This spring member applies a constant force to the piston assembly such that longitudinal movement of the piston assembly automatically occurs upon removal of pneumatic pressure to the braking system, causing the piston assembly to retract within the casing and the force transfer lever to rotate in a direction to initiate a brake application. Thus, once the train is removed from the train consist and the air supply for the pneumatic braking system has been disconnected, the brakes of the train are automatically applied. A manual quick release system is also provided which allows the parking brake to be released during shunting operations or anytime that it is desirable to move the vehicle in the absence of air.

Abstract: A method and apparatus are disclosed for congestion management in a multi-branch Internet Protocol (IP)-based private branch exchange (PBX) switch. The multi-branch IP-based PBX switch is interconnected through (i) a packet network referred to as the primary network, such as a wide area network (WAN), and (ii) an alternate network, such as the public switched telephone network (PSTN),. Packet phone adapters (PPAs) associated with each packet telephone unit monitor packet telephone calls and report delay information to communication servers. The communication server can reroute the packet telephony calls through the secondary network upon detection of congestion in the underlying primary network, thereby preserving voice quality. The packet phone adapter (PPA) will discard records collected from calls whose duration is below a minimum value, to ensure reliable congestion information. Each communication server records reported voice quality of service information in a congestion control database. An overload control process processes each call set up request and determines if the requested path is congested. If a requested path is congested, then the overload control process may forward the call using the secondary network.

Title: Downhole separation and injection of produced water in hydrocarbon wells using partial gas lift
Inventor: ZAHACY TODD
IPC: E21B43/12
Filed: 2001-03-05
Abstract: A method and system for the downhole separation and injection of a predominately water component of the mixture produced from a naturally flowing or gas-lifted hydrocarbon well. The produced mixture is delivered to a separator located in the wellbore above an injection formation, the separator comprising a gas-liquid separator and an oil-water separator. The produced mixture is admitted to a gas-liquid separator to separate the free gas from the produced mixture. The gas-depleted produced mixture is then admitted to an oil-water separator where the produced mixture is separated into a predominately water component and a predominately hydrocarbon component. The separated gas and the predominately hydrocarbon component are delivered to the surface, separately or commingled. The predominately water is injected in the injection formation accessible through the same wellbore, and located below the separator. The predominately water component is separated at a sufficiently elevated location with respect to the injection formation to permit the predominately water component to be delivered to the injection formation under the force of gravity. This invention achieves downhole water separation and injection without having to install downhole pumps to re-inject the water contained in the produced mixture.
