PNEUMATIC SPRING ASSEMBLY AND METHOD OF DETERMINING VEHICLE SUSPENSION ELEMENT PARAMETRE Russian patent published in 2010 - IPC H04B5/00 B60G17/00 

FIELD: physics; control.

SUBSTANCE: invention relates to systems for determining orientation and exchanging information. The device has a first end element, a second end element, a flexible wall, a transceiver, a responder and a sensor. The method involves powering the transceiver and radio transmission of electromagnetic oscillations, receiving electromagnetic oscillations and that way powering the responder, receiving a distance signal depending on distance between the transceiver and the responder, generation of the output signal of the sensor, modulation of electromagnetic oscillations depending on the distance signal and output signal of the sensor using the responder, determination of the numerical value of the distance and value of the parametre of the vehicle suspension element based on modulation using the transceiver.

EFFECT: increased accuracy of determining suspension parametres.
