Abstract
A method for determining a rotational speed of a rotating object of a vehicle includes providing information unrelated to the rotational speed of the object of the vehicle using an electronic device and providing information related to the rotational speed of the object of the vehicle using the electronic device. One example of a system employing this method is a tire pressure sensor system. The tire pressure sensor provides information regarding the pressure of the tire of the vehicle. Likewise, a periodicity in a signal transmitted by a transmitter associated with the tire pressure sensor can be used to determine the rotational speed of the wheel of the vehicle to which the tire is attached.
