Abstract: A living body monitoring activity system detects major activities, or feeble living body activities. In a method for monitoring existence of human movements or living body activities in living environments (e.g., sleeping activities involving a bed, a Futon-mat, a pad, or a Tatami-mat), an optical fiber type flat shaped body sensor including an optical fiber affixed or fitted to a flat shaped body is used, and light is emitted into the optical fiber from a light source, and changes of polarized wave conditions of light propagating in the optical fiber are brought about by changes in form of the optical fiber type flat shaped body sensor caused by human movements or living body activities and are detected by a measuring apparatus for polarized wave fluctuations so human activities or movements are discriminated based on the detected value of the polarized wave fluctuations.

Abstract: An energy station includes a generating unit and a separate remotely located dispensing unit. The generating unit includes a housing having an electrolyzer for generating hydrogen and a storage unit for storing hydrogen from the electrolyzer. The dispensing unit includes a housing for dispensing hydrogen from the generating unit. The generating unit is located at a first location and the dispensing unit is located at a second location away from the first location. For example, the generating unit may be located outside the building and the dispensing unit may be located inside a garage. Also disclosed is a generating unit having a fuel cell for supplying electricity to the building and a heat exchanger for supplying heat to the building.

Abstract: A cooling system for the shutdown process in a fuel cell powered vehicle system for eliminating the detrimental effects of voltage persistence in the fuel cell including a volume of fluid coolant at ambient temperature, a pump, a fluid circuit interconnecting the pump and the coolant reservoir with a section of a cooling system that circulates through the vehicle fuel cell stack, and a controllable valve system whereby, at the occurrence of vehicle shutdown, the ambient temperature fluid in the reservoir is directed to a section of a cooling system that circulates through the vehicle fuel cell stack.

Abstract: Apparatus for electrically isolating interconnecting station nozzle and vehicle receptacle components during the refueling of high pressure gas into a vehicle tank comprising an electrically isolated vehicle tank inlet receptacle engageable with a refueling nozzle wherein the receptacle includes an assembly of mutually engageable electrically insulating media in conjunction with the vehicle receptacle mount to prevent electrical contact from the refueling nozzle to the vehicle chassis and gas tank in the refueling gas flow conduit system.

Abstract: An energy station includes a generating unit and a separate remotely located dispensing unit. In one aspect, the generating unit includes a housing having a reformer for generating reformate from a fuel stream, and a storage unit for storing the reformate. The dispensing unit includes a housing for dispensing reformate from the generating unit. The generating unit is located at a first location and the dispensing unit is located at a second location away from the first location. For example, the generating unit may be located outside the building and the dispensing unit may be located inside a garage. Also disclosed is a generating unit having an electrochemical cell, which may be operated as either a fuel cell for supplying electricity to the building or a hydrogen pump for purifying the reformate.
