摘要： A tire monitor (124, 126, 128, 130) for mounting to a vehicle as part of a remote tire monitoring system (102) includes a tire condition sensor to produce a tire condition signal, a controller (132) coupled to the tire condition sensor to control operation of the tire monitor, and a radio circuit coupled to the controller to transmit radio signals based at least in part on the tire condition signal. A shock sensor is coupled to the controller of the tire monitor to produce a motion signal indicating motion of the tire monitor.

摘要： In a liquid sensing system (10), an RF signal is applied to a series-resonant circuit. The coil (65) of the resonant circuit is placed proximate to a fuel tank (15), causing electromagnetic radiation to propagate into the fuel space. The fuel acts as an electrical load to the resonant circuit in a manner proportionate to the volume of fuel in the tank and/or to variations in electrical properties of the fuel itself. The loading effect of the fuel can change the resonant frequency and/or the Q of the resonant circuit. The loading effect of the fuel is determined by monitoring a change in one or more electrical parameters associated with the excited resonant circuit, such as a voltage across the resistor in the resonant circuit. Changes in this voltage are analyzed by a controller, the result of which is used to output a value indicative of level and/or composition of the fuel.
