A self-tuning duplicating transceiver is provided. The transceiver includes a microprocessor, a transmitter and a receiver. The transmitter includes an electrically tunable radio frequency oscillator, and the receiver includes a counter for determining an edge count associated with a received signal. The microprocessor is programmed to receive an unknown signal with the receiver and use the counter to determine the edge count thereof, and electrically tune the transmitter oscillator to a carrier frequency corresponding to the edge count for the unknown signal.

Self-tuning transmitter

A remote access device which may comprise an antenna having a first inductor with a first axis, a second inductor with a second axis, and a third inductor with a third axis, where the first, second and third axes may be oriented substantially perpendicular to each other, respectively, such that the first inductor generates a first magnetic field associated with a first plane, the second inductor generates a second magnetic field associated with a second plane different than the first plane, and the third inductor generates a third magnetic field associated with a third plane different than the first and second planes. The remote access device preferably includes a single form for the first, second and third inductors, where the first, second and third inductors are each wound on the form.

Remote access device having multiple inductive coil antenna

A tire monitoring system for a vehicle. The tire monitoring system includes a sensor assembly mountable on a wheel and has a first sensor for detecting a tire parameter and a second sensor for detecting proximity of the sensor assembly to the wheel. The sensor assembly is detached from the wheel when the second sensor is not proximate to the wheel.

Tire monitoring system

For use in a tire pressure monitoring system, an initiator generator includes an oscillator/divider configured to generate an output signal in response to a switched, regulated voltage. The output signal has a fundamental frequency and a gating frequency.

Tire pressure monitoring system with low frequency initiation approach

In a system for remote monitoring of tire pressure in a vehicle having front tires including a right tire and a left tire, and rear tires including a right tire and a left tire, a system and method are provided for automatically identifying tire location. A transmitters mounted in each tire transmits tire information signals conveying tire pressure data and associated tire rotation direction data. A vehicle mounted receiver has a location a first distance from the front tires and a second distance from the rear tires, the first distance being different from the second. A vehicle mounted controller in communication with the receiver determines whether pressure data is associated with a front tire or a rear tire based on the strength of the tire information signal, and whether pressure data is associated with a right tire or a left tire based on the associated rotation direction data.

System and method for tire pressure monitoring providing automatic tire location recognition

In a system for remote monitoring of vehicle tire pressure, a system and method for automatically identifying tire location. A tire pressure monitor mounted in each tire includes a sensor for sensing tire pressure, a transmitter for transmitting a signal representative of the sensed tire pressure, and a magnetic switch for actuating the transmitter. An electromagnets is mounted on the vehicle in proximity to each tire location and generates a magnetic field causing the magnetic switch to actuate the transmitter of the associated tire pressure monitor. A controller mounted on the vehicle is provided in communication with the electromagnets, processes the tire pressure signals from the transmitters, and conveys tire pressure and location information to a user. The controller energizes the electromagnets so that each received tire pressure signal is automatically associated with a specific tire location.

System and method for tire pressure monitoring including automatic tire location recognition

In a system for remote monitoring of vehicle tire pressure, a system and method for identifying tire location. A tire pressure monitor for each tire includes a sensor for sensing tire pressure, a transmitter for transmitting a signal representative of the sensed tire pressure, and a sensor for sensing an impact to the tire and for actuating the transmitter to transmit a tire pressure signal in response. A receiver for mounting on the vehicle receives the tire pressure signals. A controller for mounting on the vehicle communicates with the receiver and is for use in conveying tire pressure and location information to a user. When the vehicle is stationary, each tire is struck in a preselected sequence so that each received tire pressure signal is automatically associated with one of the plurality of tire locations.
