    摘要: RFID and sensor assemblies for vehicles in which an interrogator transmits RF signals and receives responsive RF signals from the RFID assemblies. Each RFID assembly includes a sensor and an RFID switch which receives an RF signal from the interrogator and upon receipt of a signal containing its identification, enables transmission of a signal from the sensor from which a property being monitored by the sensor is determinable. The sensor may be a SAW sensor which modifies a received wave as a function of the property being monitored by the sensor and thus transmits a modified wave. Each RFID assembly may include an antenna arranged to receive signals from and provide signals to the interrogator. The RFID switch is arranged to connect or disconnect the sensor from a circuit dependent on whether the antenna receives a particular signal associated with the RFID assembly.

    摘要: The fuel gage of the present invention uses a combination of (i) one or more load cells or fuel level measuring devices, plus in some cases other sensors which measure the pitch or roll angle of the vehicle or the fuel density, to approximately measure the quantity of the fuel in the tank and (ii) a processor and algorithm, which may be a look-up table or formulae, to correct for the inaccuracies arising from the pitch and roll angles of the vehicle, other external forces or from variations in fuel density. Although several weighing systems are disclosed for illustrative purposes, the invention applies to any method of making an approximate measurement of the fuel quantity (weight or volume) and then using analytical techniques to improve on the measurement.

    摘要: System and method for preventing vehicle accidents in which the absolute position of the vehicle is determined, e.g., using a satellite-based positioning system such as GPS, and the location of the vehicle relative to the edges of the roadway is then determined based on the absolute position of the vehicle and stored data relating to edges of roadways on which the vehicle may travel. A system or component within the vehicle is initiated, e.g., an alarm or warning system, or the operation of a system or component is affected, e.g., an automatic guidance system, if the location of the vehicle approaches close to an edge of the roadway or intersects with an edge of the roadway.

    摘要: Electrical system in a vehicle including a plurality of devices used in the operation of the vehicle, a single communication bus to which the devices are connected and a single power bus to which the devices are connected. The devices include at least one accelerometer and/or at least one airbag initiator. The power bus provides power to the devices while the communication bus provides communications to and from the devices to, e.g., a control module. The devices are preferably provided with individual device addresses such that each device will respond only to its device address. Each bus may include a pair of wires and a single pair of wires may constitute both buses.
