Abstract

A device for detecting the theft of an object, intended to be integrated to said object, includes an antenna for receiving a remote-supply signal and means for detecting an interruption of the remote-supply signal. Means for delivering an alarm signal when the interruption of the remote-supply signal is detected are also provided.

Claims

1. An object (10) comprising a case (12) and a device (5;

135) for detecting the theft of the object (10), intended to be integrated to said object, the device comprising;

an antenna (50) for receiving a remote-supply signal;

a second antenna (42);

an accelerometer (34);

means (32) for detecting an interruption of the remote-supply signal and for detecting a displacement of said object from a signal provided by the accelerometer;

means (40) for delivering an alarm signal via the second antenna when the interruption of the remote-supply signal and the displacement of the object are simultaneously detected; and

a battery (46) capable of powering all components of the object and capable of being charged with the remote-supply signal,

wherein the case at least partly contains the detection device and wherein the case (12) has an external aspect imitating the aspect of a timepiece and/or jewelry item.

2. The object of claim 1, wherein the detection device (5;

135) further comprises means (36) for determining, the position of the object.

3. The object of claim 1, wherein the case (12) has the aspect of a watch case.

4. The object of claim 3, further comprising a strap (14) containing the remote-supply signal reception antenna (50).

5. A system comprising the object (10) of claim 1 and a support (20) of said object, the support comprising an antenna (54) for transmitting the remote-supply signal.
