摘要： A tire monitor system employs a single RF detector mounted on the vehicle. The tire monitor system also includes a control unit and a receiver. The single RF detector is positioned to be proximate a front axle or a rear axle. The RF detector also may be positioned off-center. The control unit distinguishes front tire monitors from rear tire monitors by comparing a number of RF transmissions received by each tire monitor. The control unit also may distinguish between left tire monitors and right tire monitors by comparing the number of RF transmissions received by each tire monitor. In other embodiment, the tire monitor system may further use a received signal strength and/or acceleration signals to determine position information of the tire monitors.

摘要： In a liquid sensing system, an RF signal is applied to a series-resonant circuit. The coil of the resonant circuit is placed proximate to a fuel tank, 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.

摘要： A remote tire monitor system includes a control unit and a plurality of tire monitors mountable on respective wheels of a vehicle to transmit radio signals to the control unit. The tire monitors each include a pair of motion sensors such as shock sensors and a control circuit configured to determine position information for the respective tire monitor based on first and second shock sensor signals from the pair of shock sensors. The shock sensors produce an output voltage proportional to a change in applied force. Therefore, the offset created by centrifugal force in previously used accelerometers is absent, simplifying design of the tire monitors.

摘要： A tire monitor system and method rely on only two RF detector mounted on the vehicle, one in close proximity to one of the front wheels and the other in close proximity to one of the rear wheels. An RF detector can distinguish between its local transmitter and the other transmitter on the same axle by the amount of signal received. Every time the controller decodes transmitted RF data, the controller looks to see if and which RF detector has detected the transmission. The controller can then determine over a short period of time which sensor identifier belongs to which corner of the vehicle.

摘要： A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.

摘要： An automotive urea solution monitoring device is deployed in conjunction with the urea tank of a selective catalytic reduction vehicle. An RF signal of a constant frequency may be generated across a resonant circuit, which may be comprised of an inductor and a PCB trace capacitor, or the like. Electromagnetic radiation is propagated into the automotive urea solution in the urea tank. The conductivity and dielectric properties of the liquid change the impedance of the discrete/trace capacitor and or the discrete/trace inductor. These changes are proportional to ammonia content, temperature, and/or level of the automotive urea solution in the urea tank and are preferably detected by a microcontroller, or the like, and then transmitted to a selective catalytic reduction vehicle engine management system, or the like.
