摘要： Power transmission monitoring systems includes rotation speed sensors mounted to hubs of a power transmission pulley. A sensor comprises a rotation sensing device, and a controller receiving rotation data therefrom and determining rotation speed of the pulley. A transmitter transmits rotational speed of the pulley to a receiver, which may include or be connected to a device that compares the rotational speed to rotational speed in transmissions from other sensors to determine slip in the power transmission system. The rotation speed sensing device may be an accelerometer, or a gravitational torque harvester. A harvester might include a rotor body rotating with the pulley and mounting induction coils, and a gravitational torque stator mounting an induction magnet and including an air vane damper maintaining the stator stationary with respect to the rotor, through air resistance. The transmissions may be employed to monitor, maintain and repair the power transmissions system.

摘要： A method carried out in a wheel unit of a tire pressure monitoring system comprises detecting, using a controller in the wheel unit, increases and decreases in loading of a tire on a wheel associated with the wheel unit during acceleration and deceleration. Front/rear position of the wheel unit on a vehicle mounting the tire pressure monitoring system is determined, using the controller in the wheel unit, based on the loading and unloading of the tire and wheel during acceleration and deceleration. Rotation direction of the wheel in the wheel unit is determined and the controller in the wheel unit determines left/right position of the wheel unit on the vehicle based on the rotation direction of the wheel. An indication of the front/rear and left/right position of the wheel on the vehicle and an identification unique to the transmitting wheel unit are transmitted.

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 method for determining change of direction of a vehicle includes steps of maintaining a rolling window of ABS data indicative of ABS tooth count and capturing a relevant rolling window of ABS data at the predetermined one-measurement point; storing the rolling window of the ABS data indicative of ABS tooth in a buffer; monitoring the ABS data and detecting a valid stop event which causes the rate of change of ABS tooth count to substantially decrement to zero; and monitoring the ABS data and detecting a valid move event which causes the rate of change of ABS tooth count to substantially increment from zero. The method also includes steps of determining a pre-stop phase relationship between at least two wheels based on the ABS tooth count stored in the buffer immediately prior to the valid stop event; determining a post-start phase relationship between at least two wheels based on the ABS tooth count stored in the buffer immediately subsequent to the valid move event; and correlating the pre-stop phase relationship and the post-start phase relationship to determine change of direction and confidence level.

Alternatively, the systems and methods provide for transmitting time differences to the electronic control module. The electronic control module correlates information transmitted from the wheel unit with antilock brake system data. A location of the wheel mounting the sensor is determined and the sensor identification is assigned.

摘要： A tire monitor system includes a tire monitor sensor unit that has a tire pressure detector, a coupler and a tire valve. The tire valve operates as an antenna to transmit tire data from the tire pressure detector. The coupler provides a capacitive coupling that removably couples the tire pressure detector and the tire valve. The coupler includes two metal layers separated by a dielectric layer. The two metal layers may be formed by the tire valve and a connection tube.

摘要： A TPM system wheel unit measures rotational period over a number of wheel revolutions, calculates a value of a period of the revolutions and wirelessly transmits the calculated value of the period to a tire pressure monitoring system receiver in the vehicle mounting the wheel. Alternatively, each wheel unit transmits an RF burst of a predetermined length and a received RF burst envelope modulated with a periodic modulation pattern is used to calculate the period of one wheel rotation for each wheel. A central vehicle electronic control unit monitors wheel speed signals for each wheel of the vehicle and calculates a period for the wheel speed signal for each wheel of the vehicle, bounded by a rolling window which may be of variable length. The calculated values are compared and the wheel unit and the wheel location are correlated therefrom.
