Abstract: A method is provided for selectively providing power to at least one component of a vehicle-based receiver module for determining the presence and validity of a transmitted RF signal. The RF signal is a request signal for activating a respective vehicle accessory function. Power is provided to a receiver for a first period of time. The receiver is operated to receive any RF signal that may be present from a remote transmitting device. A received signal strength indicator (RSSI) associated with operating the receiver is determined. A determination is made whether the RSSI is greater than a first predetermined threshold. The power is terminated to the receiver after the first period of time if the RSSI is not greater than the first predetermined threshold.

Abstract: A method of heating a fluid utilizing a process heater having one or more first combustion zones and one or more second combustion zones. The combustion of a fuel is divided between the first and second combustion zones. The oxygen is provided for combustion within the first combustion zone by one or more oxygen transport membranes that contribute between about 50 and 99 percent of the stoichiometric amount of oxygen required for complete combustion of the fuel passing through the process heater. A supplemental or secondary oxidant is introduced into second combustion zone to complete combustion of the fuel and thereby produce a flue gas stream containing between about 1 and 3 percent oxygen to ensure complete combustion of the fuel. In this manner, the surface area of the oxygen transport membranes may be reduced below the surface area that otherwise would be required if 100 percent of the oxygen were contributed by the oxygen transport membranes.

Abstract: A method is disclosed for controlling addition of a supplementary oxygen stream into a steam methane reformer utilizing both the supplementary oxygen stream and a primary oxidant stream to support combustion of a fuel stream by burners firing into a radiant section of the reformer. The combustion generates heat to support endothermic heat requirements of the reforming reaction conducted in reformer tubes to obtain an enhanced rate of production of a product gas stream produced by the endothermic reaction. In the method, a temperature is obtained that is at least referable to a reformer tube wall temperature measured at a location of inlet regions of the reformer tubes at which a maximum temperature is produced at the enhanced rate of production.

Abstract: A system for cooling one or more discrete superconducting devices wherein a primary refrigerator subcools cryogenic liquid for desubcooling in the devices and subsequently resubcools this liquid in a recirculation loop, and additional cryogenic liquid is maintained in a subcooled condition within a reserve storage container by diversion of some of the refrigeration generated by the primary refrigerator into the reserve storage container.

Abstract: A method of heating a fluid in a fluid heater integrated with a gas turbine. Fuel is burned in a radiant section of the fluid heater to heat the fluid and to produce combustion gases for the heating a downstream convective section. The combustion is supported by a combined oxidant stream. An oxygen containing stream or the combined stream, which is made up in part by the oxygen containing stream is preheated through indirect heat transfer with a first gas turbine exhaust stream produced by the gas turbine. A second gas turbine exhaust stream, also produced by the gas turbine is combined with the oxygen containing stream to form the combined oxidant stream. As such, the available heat energy supplied to the fluid heater is supplied not only by the combustion but also the gas turbine. This allows for the fuel to be conserved or for increased fluid throughput.
