摘要： An apparatus for monitoring an article or system, particularly an LP or propane tank, includes a transmission unit, a base unit and a host unit. The transmission unit is disposed on or near the article or system and detects at least one parameter related to the article or system and send information related to the detected parameter. The base unit is disposed at a predetermined location remote from the article or system. The base unit receives information related to the detected parameter from the transmission unit. The host unit is disposed at a location remote from the base unit and the transmission unit. The host unit receives information related to the detected parameter from the base unit for management purposes. A method of monitoring an article or system such as a fuel tank is also disclosed.

摘要： The capacitance of a shielded capacitive load cell is determined so as to minimize the effect of stray or parasitic capacitance between the load cell and other objects including the shield. The load cell conductors are coupled across input and output terminals of an operational amplifier that is tied to a reference voltage. A constant current is applied to the load cell, and the resulting rate of change in voltage at the amplifier output is measured as a representation of the load cell capacitance. In a vehicle seat sensor application including an electromagnetic interference shield between the load cell and the seating surface, the amplifier output is coupled to the load cell electrode furthest from the shield, the amplifier maintains the other load cell electrode at a virtual reference voltage, and the shield is tied to the reference voltage.

摘要： A vehicle occupant sensing system for detecting a condition of a vehicle seat assembly having a lower seat cushion supported by a seat pan. The system has a tray with a plurality of pedestals disposed between the seat pan and the cushion. The system also has a plurality of sensor assemblies, each defining a force responsive axis and disposed between the lower seat cushion and tray. The pedestals support some of the sensor assemblies such that the force responsive axes of the sensor assemblies are substantially aligned with the occupant's weight load. Furthermore, the system may be employed in a seat assembly to detect a condition thereof. The tray allows addition of safety features in the vehicle seat assembly such that the seat more effectively retains the occupant, and yet the tray positions the sensor assemblies to be responsively aligned with the occupant's weight load despite these additional features.

摘要： The present invention relates to a wireless remote fuel gauge (10) comprising a tank gauge (12) positioned on a fuel tank (16A, 16B). The tank gauge (12) comprises a tank gauge microprocessor/analog converter (12A) electrically connected to a tank gauge power line (12F). A tank gauge transmitter (12B) is electrically connected to the tank gauge microprocessor/analog converter (12A). The tank gauge transmitter (12B) functions to transmit, by radio frequency, a level of fuel (18) information within the fuel tank (16A, 16B). A tank gauge indicator (12D) is mechanically connected to the tank gauge microprocessor/analog converter (12A). The tank gauge indicator (12D) functions to allow a consumer to visually monitor the level of fuel (18) within the fuel tank (16A, 16B). The tank gauge float (12G) maintains position on the level of fuel (18) within the fuel tank (16A, 16B). A remote unit (14) in radio frequency communication with the tank gauge (12) is positioned within a house (22) preferably within a hallway (22A, 22B). The remote unit (14) comprises a remote unit microprocessor (14A) electrically connected to a remote unit power line (14F). A remote unit transmitter (14B) is electrically connected to the remote unit microprocessor (14A). The remote unit transmitter (14B) functions to transmit, by wireless communication, a request for the level of fuel (18) information to the pre-existing tank gauge (12C). A remote unit receiver (14C) is electrically connected to the remote unit microprocessor (14A). The remote unit receiver (14C) functions to receive the level of fuel (18) information from the tank gauge transmitter (12B). A remote unit indicator (14D) is electrically connected to the remote unit microprocessor (14A). The remote unit indicator (14D) functions to visually exhibit the level of fuel (18) information to a user. A remote unit wireless communication means (14G) electrically connected to the remote unit microprocessor (14A). The remote unit wireless communication means (14G) functions to receive therethrough a request for the level of fuel (18) from a fuel company and transmit therethrough the level of fuel (18) to the fuel company.
