Abstract

Abstract A device for protecting premises such as residences, the device comprising at least one human presence detection sensor, a processing device and reaction mechanisms. The processing unit comprises mechanisms for modifying the operation of the reaction mechanisms each time the human presence detection sensor is activated. The reaction mechanisms may be of a conventional type comprising essentially light or acoustic devices. The device comprises mechanisms for simulating a presence inside the premises, controlled by the processing unit to simulate a presence in the occupant's absence. These simulation mechanisms may include lighting of the various rooms in the protected premises and activation of a tape recorder to play back human voices.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 98 words
A device for the protection of premises such as residences, comprising two chains of human presence detection sensors, a processing unit and reaction mechanisms, one of said chains of human presence detection sensors being located outside said premises, and one of said chains of human presence detection sensors being located inside said premises, said reaction mechanisms including means for simulating a presence inside the premises, controlled by the processing unit to simulate a human presence, and said processing unit including means for modifying the operation of the reaction mechanisms each time a human presence detection sensor is activated.
Claim 2
Independent Claim 98 words
A device for the protection of premises such as residences, comprising two chains of human presence detection sensors, a processing unit and reaction mechanisms, one of said chains of human presence detection sensors being located outside said premises, and one of said chains of human presence detection sensors being located inside said premises, said reaction mechanisms including means for simulating a presence inside the premises, controlled by the processing unit to simulate a human presence, and said processing unit including means for modifying the operation of the reaction mechanisms each time a human presence detection sensor is activated.
Claim 3
Dependent Claim 36 words
A device as set forth in claim 1, wherein said processing unit includes means for increasing, for a definite time period, the sensitivity levels of the human presence detection sensors after these have been activated once.
Claim 4
Dependent Claim 37 words
A device as set forth in claim 1 or 2, including means controlled by the processing unit to inform the occupants of the premises that an attempted break-in has been detected by the human presence detection sensors.
Claim 5
Dependent Claim 19 words
A device as set forth in claim 1 or 2, including distant alarm mechanisms, controlled by the processing unit.
Claim 6
Dependent Claim 19 words
A device as set forth in claim 1 or 2, including means for neutralizing an intruder inside the premises.
