Title: Closure mechanism with integrated actuator for subsurface valves
Inventor: TROTT DOUG
IPC: E21B34/00
Filed: 2002-11-25
Abstract: A subsurface safety valve has a closure sleeve (122) or rod (38) mounted below the closure mechanism. Control signal pushes the sleeve up (uphole) or down (downhole), whichever is applicable, which causes the closure element (10) to rotate (or slide, or otherwise translate) to its open position. A loss of control signal allows the closure spring (24) to push the sleeve or rod downhole (or uphole, whichever is appropriate). This movement causes the closure element to be driven to its closed position against the seat.

Title: Self-monitoring radio network
Inventor: HALL RONALD W
IPC: H04B17/00
Filed: 2002-12-19
Abstract: A scheme of identifying nonfunctional two-way radios from among a known group of two-way radios expected to be operating within a region may include establishing a corresponding window of time for each of the two-way radios expected to be operating within the region. For each of the established windows of time, a transmission from the corresponding radio is awaited. If, for a particular radio, no transmission is detected within its corresponding window of time, the absence of the transmission is recorded. Finally, if, for a particular radio, the number of times absence of transmission has been recorded exceeds a threshold, the particular radio is identified as nonfunctional.

Title: Storage tank overflow containment apparatus
Inventor: CRICHTON BRIAN
IPC: B65D90/26
Filed: 2004-11-16
Abstract: The present invention is a spill containment apparatus that may be mounted to the vent pipe of a liquid storage tank. The apparatus comprises a canister forming a reservoir for receiving liquid overflowing through the tank vent. If the overflow volume does not exceed the reservoir capacity, the liquid in the reservoir drains back into the tank when the tank is drawn down. If the overflow volume exceeds the reservoir capacity, the excess liquid is diverted through a canister outlet to a collection receptacle. In either event, the overflowing liquid never contacts or contaminates the exterior surfaces of the tank roof and walls, or the fill or natural soil in the vicinity of the tank. A canister vent that allows passage of vapours from the tank to the atmosphere during non- overflow conditions. If an overflow floods the canister, a check valve closes off the canister vent, thus preventing spillage through the canister vent.

Title: Method and apparatus for identifying transmitters in a wireless communication system using power predictions
Inventor: LIN IE-HONG
IPC: H04W64/00
Filed: 2003-10-21
Abstract: Identification of transmitters for signals received by a terminal. To determine the transmitter of a given received signal, a list of candidate transmitters that may have transmitted that signal is determined. A coverage zone to use for the received signal is also determined. This coverage zone is the area where the terminal may receive the signal being identified. The predicted power for each candidate transmitter is then determined, e.g., using a path loss prediction model and the coverage zone. The predicted powers for the candidate transmitters are compared (directly or relatively) against the measured power of the received signal. The candidate transmitter with (direct/relative) predicted power closest to the (direct/relative) measured power is deemed as the one that transmitted the signal. Propagation delays may also be predicted and used for transmitter identification. The identified transmitters may be used to determine a position estimate for the terminal.

Title: Method and system for controlling fluid flow in a fuel processing system
Inventor: MUELLER FORTUNAT JAKOB
IPC: H01M8/06
Filed: 2003-10-30
Abstract: Fuel processing systems, which reform a hydrocarbon fuel to produce hydrogen suitable for use in a fuel cell, have multiple air inlets for various process steps. Controls and feedback loops are correspondingly complex. Controlling the multiple airflows to a pressurized fuel processor using a single onboard compressor and a number of low pressure drop valves is a significant challenge to overcome in the process of getting a reformer on board a vehicle. A method has been developed for controlling the compressor speed based on the airflow demand of the partial oxidation (POX) zone, without direct feedback from the other airflows in the system. This ensures that the principal zone of air consumption always gets the appropriate amount of air, thus controlling the temperature of that zone and the reaction chemistry effectively. This method also allows removal of extra flow sensors from airflows where the effect of changed airflow (e.g. temperature change) can be used as a feedback to an air controller instead of the actual airflow itself. Similar principles are applicable in the control of other flows, such as fuel and water, when several flows are fed by a common source.
