Estimating the term…
A wheel, particularly for a vehicle, includes at least a portion formed from non-metallic material which incorporates at least one sensor indicative of a condition sensed. A wheel is molded from a fiber reinforced plastics material and incorporates passive sensors capable of indicating conditions of the wheel or the tire associated with it (e.g., tire pressure or torque transmitted). The sensor output is processed by an ASIC device to provide an output signal to a communications device also mounted on the wheel. The ASIC and communications device are powered by a virtual battery which is charged by, e.g., using electrical pulses generated by strain within the wheel itself. An id tag may be provided to identify the wheel in question.
A wheel having a structural portion formed from a non-metallic material, the structural portion incorporating as an integral part thereof a passive sensor to monitor characteristics of the wheel and/or of a tyre mounted on the wheel and/or of a fluid contained between the wheel and the tyre, whilst the wheel/tyre is in use.
A wheel according to any preceding claim including means embedded in or secured to the wheel for generating electrical power to power the components embedded in or secured to the wheel.
A wheel according to any preceding claim in combination with means external to the wheel for supplying energy to the wheel via a wireless connection.
A wheel according to any preceding claim including storage means for storing an identification code associated with the sensor;
A wheel according to any preceding claim wherein the passive sensor is a SAW device.
