Sensor assembly capable of obtaining and providing a measurement of a physical quantity, e.g., measurement of temperature and / or pressure of a vehicular tire, includes an antenna capable of receiving a radio frequency signal, a radio frequency identification (RFID) device coupled to the antenna, a sensor coupled to the RFID device arranged to generate a measurement of the physical quantity or quantities, and a switch coupled to the RFID device and arranged to connect or disconnect the sensor from a circuit with the antenna dependent on whether the antenna receives a particular signal associated with the RFID device. When the antenna receives the particular signal associated with the RFID device, the RFID device causes the switch to close and connect the sensor in the circuit with the antenna to enable the measurement generated by the sensor to be directed to and transmitted by the antenna.

Method and system for diagnosing whether vehicular components are operating abnormally based on data obtained from sensors arranged on a vehicle. In a training stage, output from the sensors during normal operation of the components is obtained, each component is adjusted to induce abnormal operation thereof and output from the sensors is obtained during the induced abnormal operation. A determination is made as to which sensors provide data about abnormal operation of each component based on analysis of the output from the sensors during normal operation and during induced abnormal operation of the components. During operation of the vehicle, the output from the sensors is obtained and analyzed, e.g., by inputting it into a pattern recognition algorithm or neural network generated during the training stage, in order to output an indication of abnormal operation of any components being diagnosed.

A navigation system for a vehicle includes a vehicle-based telematics system, a vehicle-based global positioning system and a control.

The control is operable to provide an output corresponding to each of the instructions in response to a current actual geographic position of the vehicle. The control is operable to provide each instruction only when the then current actual geographic position of the vehicle at least generally corresponds to the particular geographic location associated with the instruction.

A device for monitoring a rotating shaft is provided. The device measures strain in the shaft and provides angular velocity and torque in the shaft. The device includes a sensor, sensor conditioning circuitry, a microprocessor, and a transmitter, all located on a rotating shaft. The device obtains power by harvesting mechanical energy of the rotating shaft itself. Coils are provided rotating with the shaft and permanent magnets are mounted adjacent the rotating shaft so electrical energy is induced in the coils as they rotate through the magnetic field of the permanent magnets. A battery or capacitor is connected to the coils for storing energy. A microprocessor is connected to the sensors, the storage device, and the transmitter for managing power consumption and for monitoring the amount of electrical energy stored in the storage device and for switchably connecting the storage device to the transmitter when the stored energy exceeds a threshold.

A remote vehicle control system having a base transceiver mounted in a vehicle and a mobile key fob. The base transceiver utilizes an omni-directional antenna to communicate wirelessly with the key fob via the IEEE 802.15.4 communication protocol. Additional antennas are mounted to the vehicle and are also tuned to communicate over the IEEE 802.15.4 bandwidth. The additional antennas have radiation patterns extending outwardly to various sides of the vehicle (e.g., driver, passenger and rear sides). The system provides remote control functions and enables passive keyless entry functions such as unlocking doors or trunk latches by detecting the presence of the key fob proximate to one or more sides of the vehicle based on the ability of the key fob to communicate over IEEE 802.15.4 via the additional antennas.

The invention provides a method for correspondingly marking the most protuberant part of the deformed rubber corresponding to the outer side of an automobile tire with a white fluorescent paint line and coating a red fluorescent paint line in the position which is one second distance below from the white line as a safety mark according to the allowable normal inflation pressure standard range calibrated when the tires of sedans and miniature vehicles leave the factory (for example, the allowable normal inflation pressure standard ranges of a 1.5t FIAT sedan, a 0.6t CHANG'AN STAR miniature minibus and a 1.0t LINGYANG sedan are respectively 2.3 to 2.8 Kg / cm<2>, 2.2 to 2.5Kg / cm<2> and 2.2 to 2.6Kg / cm<2>). When the red fluorescent paint line disappears and the most protuberant part of the deformed rubber on the outer side of the tire is above the white fluorescent paint line, the tire pressure is indicated to be too low, and measures, such as inflation, tire repair, etc., should be carried out. When the most protuberant part is below the white fluorescent paint line and above the red fluorescent paint line, the tire pressure is indicated to be too high, and the measure of deflation should be carried out. The method has the advantages of visibility, rapidness, convenience, safety, practicality and low cost, and is easily accepted by drivers and tire manufacturers, completed at one time in the tire manufacturer and easily generalized and applied.

A modular electronic assembly for integration with a pneumatic tire includes a mounting patch, a power source, and at least one electronic device supported by a substrate. The mounting patch is preferably adapted for positioning on the inner liner of a pneumatic tire, and the power source is at least partially embedded in the mounting patch. Such embedded positioning of the battery results in an overall structure with a lower center of gravity than previous tire electronics assemblies, thus having increased mechanical stability and survivability in a tire environment. Electronic device(s) supported on the substrate may receive power from the power source, which in some embodiments corresponds to one or more batteries. The substrate supporting the at least one electronic device may be attached to the mounting patch by a variety of fashions. Exemplary attachment configurations may correspond to an adhesive layer, a hook and loop tape combination, or physical interconnection via terminals extending from the power source through the support substrate. Exemplary electronic devices may include such components as condition-responsive devices including transducers, acoustic devices, sensors, etc. for sensing certain environmental conditions such as temperature and / or pressure, tire revolution counters, vehicle speed sensors, sidewall deflection sensors, tire displacement sensors, microprocessors, memory modules, RFID transponders, light assemblies, data transmitters and / or receivers, and power, supply components. Selected of the electronic devices (including one or more antennas associated with any RF devices) may be encapsulated by a non-conductive rubber or elastic material to facilitate effective transmission characteristics. Conductive springs, flexible conductive elastomer or fatigue-resistance metal may be used to interconnect various electronic components (such as an RF device to an antenna).

An electronic tire maintenance system is provided for measuring a parameter of a device at a first location.

In one embodiment, the device is a tire tag mounted inside a tire that measures tire data and transmits that data to a remote source in response to an interrogation request, an alert condition, or automatically on a periodic basis.
