Patent ID: 7415870

Claim:
A system for sensing at least one characteristic parameter of a tyre fitted to a vehicle, comprising: a movable unit; and a fixed unit; wherein the movable unit is combined with the tyre, wherein the movable unit comprises: a device for sensing the at least one characteristic parameter; a device for transmitting signals out of the tyre; a processing unit; a storage device; and a device for generating electrical energy; wherein the fixed unit is combinable with the vehicle, wherein the fixed unit comprises a device for receiving signals from the movable unit, wherein the processing unit and storage device carry out pre-processing of a signal generated by the sensing device and send the pre-processed signal to the transmitting device, wherein the electrical energy generating device is capable of supplying electrical energy to the processing unit and to the transmitting device, wherein the transmitted signal relates to the at least one characteristic parameter, and wherein the sensing device, the transmitting device, the processing unit, the storage device and the electrical energy generating device are produced and integrated on the same substrate by micro-electrical-mechanical system (MEMS) technology.
