Abstract: An system for monitoring the performance of a mobile environmental control unit (ECU) includes sensors for monitoring and detecting operating parameters of the ECU. A monitor processing and communications unit is coupled to the sensors for receiving and processing the operating parameter data signals from the sensors and relaying the processed operating parameter data signals to a computerized graphical user interface display via a network. The processed operating parameter data signals are graphically displayed to technical support personnel for determining problems or performance issues which may exist or may occur on an ECU remotely and offer corrective action.

Abstract: System for inflating a vehicular gas bag (10) with gas from a bottle of compressed gas (12) against an occupant (13) in an emergency include a gas pressure sensor (39) having a sensor input (20) coupled to compressed gas in the bottle prior to an emergency, and having a sensed pressure output (21). A variable gas inlet passage (15) for the gas bag has a gas inlet passage variator (22) coupled to the sensed pressure output (21), and a variable gas venting passage (16) positioned in circumvention of the gas inlet passage and inverse to the variable gas inlet passage (see 37 vs. 34), and having a gas venting passage variator (23) coupled to the sensed pressure output. A compressed gas release (25) having a compressed gas outlet (26) on the bottle is connected to the gas inlet passage (15) and to the variable gas venting passage (16). The gas pressure sensor (21) may be temperature-compensated (46-48).

Abstract: Apparatus for discharging gas from a bottle of compressed gas include a compressed gas release having on that bottle a compressed gas outlet having a closed position and an alternative open position. A shuttle has a first position spaced from that compressed gas outlet before and after opening of such compressed gas outlet and has a second position at such compressed gas outlet. The shuttle includes a temporary compressed gas flow restriction at the compressed gas outlet in the alternative open position of such compressed gas outlet. A system for discharging gas from a bottle of compressed gas closes such bottle with a burst diaphragm, subsequently penetrates such burst diaphragm, momentarily reduces flow of compressed gas from the bottle at the penetrated burst diaphragm, and thereafter removes the reduction of flow of compressed gas from the bottle at the penetrated burst diaphragm.

Abstract: Methods and apparatus for enhanced recovery of subterranean deposits employ a heated fluid driven into the subterranean formation. A heating fluid is heated at the surface of the earth remote from the subterranean formation to a heated state providing a temperature sufficient for a conversion of a liquid to a vapor phase at the subterranean formation by a transfer of heat from the heating fluid to that liquid. The heating fluid is circulated in a closed circuit extending for the heating fluid at the heated state to the subterranean formation and then back to the earth surface for repeated reheating at that surface to the heated state and for circulation of the heating fluid at said heated state to the subterranean formation.
