System for transmitting a signal indicating the functioning condition of a tire
First Claim
1. System for transmitting a signal indicating the functioning condition of a tire, the system co-operates with a device signalling the inflating condition of the tire, wherein a movable group is found in a first loading position when the tire pressure is higher than the pre-established value, the movable group is found, on the contrary, in a second unloading position when the tire pressure is lower than a pre-established value and, therefore, the tire is not suitable for a standard use, the movable group consisting of, at least, a sensor, an amplifier, a transducer and an actuator, the system is characterised by the fact that it is fitted with a switch commuting from a first to a second condition which is opposite to the first one when the group passes from the first loading position to the second unloading position to activate an apparatus sending a warning signal picked up by a receiver.

Abstract
A system for transmitting a signal indicating the functioning condition of a tire comprises a generator of electricity (B1) connected to a code generator (B3) and an oscillator (B4) capable of generating a right frequency for transmitting the coded signal; a switch (B2) enables the circuit to transmit the signal when the switch commutes; the signal is then filtered by the filter (B5), emitted through the antenna (B6) picked up by a receiver (B7) aboard the vehicle.
