| 摘要 |
A method for enabling an apparatus ( 15 ) to operate only after detecting with receiver elements ( 11 ) located proximate to the apparatus, a signal transmitted by portable transmitted elements ( 1 ), which consists in no longer taking into account detection by the receiver means ( 11 ) of the signal transmitted by the transmitting elements ( 1 ), after activating presence sensing elements ( 22 ) provided proximate to the apparatus, or integrated in the apparatus. Once activated, the presence sensing elements ( 22 ) neutralize the transmitter/receiver device ( 1, 11 ) and the apparatus can operate normally without being perturbed by possible statics or accidental losses of signal. The inventive method and device are applicable to an antitheft safety device for a motor vehicle.
