摘要： An oscillating structure is coupled to a crown portion of a tyre. The oscillating structure comprises a housing and a piezoelectric element coupled to said housing. The piezoelectric element is able to oscillate in an oscillation direction, which could match either a longitudinal or a radial direction of the tyre. An electrical signal generated by said piezoelectric element is processed so as to determine at least one operating parameter of the tyre. The processing comprises determining whether a rotation speed of said tyre is greater than a threshold speed; and, in the negative, extracting information for determining the at least one operating parameter of the tyre from a low-pass filtered signal. Such low-pass filtered signal is obtained by removing at least frequency components of said electrical signal having a frequency higher than or equal to a resonance peak frequency of said oscillating structure.

摘要： An anti-theft system for vehicles having a reduced false alarm rate comprises an arrangement capable of clearly distinguishing a vehicle movement due to an actual theft from an accidental movement. The arrangement is capable of generating an alarm after at least one of the vehicle wheels has performed at least one complete revolution. In such way, a launch of an alarm due to an accidental movement of the vehicle is practically avoided. On the other hand, in case of an actual theft of a vehicle, the alarm can be promptly launched, after few wheel rotations, for example in order to promptly locate the stolen vehicle or send a command to stop it.

摘要： A tyre comprises a piezoelectric flexing element (313) associated to an energy storage device (e.g. a capacitor). The piezoelectric flexure element is mounted in cantilever fashion in a housing (311) so as to be positioned substantially along a plane orthogonal to a radial direction (E) of said tyre and, so that a first end (315) of the piezoelement is restrained to the housing. A loading mass (312) is coupled to the second end (316) of the piezoelectric flexure element. A small gap (314) is formed between the inner walls of the housing and the outer surface of the loading mass, in order to allow limited flexure of the piezo-electric element. The housing including the piezoelectric is mounted in a tyre portion in correspondence of a tread area of the tyre, preferably on the inner surface of the tyre. The piezoelectric element flexes under the action of the radial acceleration when the tyre rotates. The loading mass and the gap are chosen to obtain: a) small entity oscillations of the flexure element substantially during a complete revolution of the tyre, when the tyre rotates at low speed; b) large entity oscillations of the flexure element substantially only during the passage of the tyre portion including the piezoelelectric element in the contact patch. Sufficient electrical power for powering an electronic device included within the tyre is obtained, together with a long durability of the piezoelectric element.
