摘要： A pressure sensing circuit for use with a wireless sensor that includes an antenna and a pressure sensing element. The antenna includes a first pole and a second pole and is operable to transceive radio frequency signals between the wireless sensor and a wireless data collecting device. The pressure sensing element includes an electrical circuit and a diaphragm. When pressure is applied to the diaphragm, a characteristic of the electrical circuit changes. The changing of the characteristic of the electrical circuit causes one or more RF characteristics of the wireless sensor to change, which is interpretable to determine a pressure being applied to the pressure sensing element.

摘要： A wireless sensor includes an antenna, a tuning circuit, a pressure sensing circuit, a processing module, and a transmitter. Collectively, the pressure sensing circuit, the antenna, and the tuning circuit have one or more radio frequency (RF) characteristics and the pressure sensing circuit causes the RF characteristic(s) to vary with varying sensed pressures. The processing module detects a variance of the RF characteristic(s) from a desired value. In response to the detecting of the variance, the processing module adjusts the tuning circuit to substantially re-establish the desired value of the RF characteristic(s). The processing module generates a message regarding the adjusting of the tuning circuit, wherein a level of the adjusting is representative of a variance of pressure sensed by the pressure sensing circuit. The transmitter transmits the message.

摘要： A self-powered tire pressure sensor device. The sensor device includes a power circuit, an air pressure measurement sensor, a signal circuit and a wireless transmission circuit. The power circuit converts mechanical acceleration experienced by the device into electrical potential using an electromechanical transducer. Mechanical acceleration due to collisions between the mobile sensor device and the wall of the tire while the tire is in motion cause the transducer to emit a small electrical charge. An electrical potential storage element in the power circuit accumulates and stores the charge as electrical potential. Alternatively the power circuit receives and converts electromagnetic energy into electrical potential. The electrical potential powers an air pressure measurement sensor within the tire. A signal circuit and wireless transmission circuit transmit the measurement to a chassis-mounted receiver, which makes the tire pressure measurement available to systems remote from the tire.

The transponder coil (4) and/or the read coil (2) are disposed as flat coil (6) on the inside and/or outside of a cylindrical periphery (9, 10) of the stator and/or rotor (11). A layer (17, 18) of a material having high magnetic permeability is provided between the flat coil (8) and the rotor (11) or stator (1), preferably in the form of a foil of an amorphous ferritic material (17) or of a non-conducting ferritic metal (18).

摘要： According to the present invention, there is provided a tire pressure monitoring system that includes a first transceiver provided on a body of a vehicle and a second transceiver provided on a wheel of the vehicle. The first transceiver transmits a request signal conveying first information. The second transceiver receives the request signal and transmits, in response to receipt of the request signal, a response signal that conveys a tire pressure information indicating the inflation pressure of a tire fitted on the wheel and second information having a predefined relationship with the first information. The first transceiver receives the response signal, identifies the received response signal as being transmitted by the second transceiver based on the fact that the second information is conveyed by the received response signal, and determines the inflation pressure of the tire based on the tire pressure information contained in the identified response signal.

摘要： A device for maintaining a desired inflation pressure within a tire mounted on a wheel of a vehicle which includes a microcompressor having a flexible compression chamber and a magnetic element not on the wheel. As the compressor passes the magnet each wheel revolution, a small amount of atmospheric air is pumped into the tire, if needed. The magnet and the compressor need no other contact with the vehicle or the wheel and require no energy source on the wheel. An alternative embodiment uses an electrical coil on the wheel to pass the magnet inducing a voltage that drives a compressor on the wheel. As the coil passes the electromagnet it provides a split transformer that transfers electrical power to the wheel and permits two-way pulse data communication between the wheel and the vehicle.
