Patent ID: 7893826

Claim:
An alarm system intended to trigger an alarm signal upon deviation from at least one environment-dependent reference predetermined for a specific environment, the alarm system comprising: at least one portable unit having a size not greater than a mobile telephone and intended to be placed in said environment, each portable unit comprising: a sensor system that records a normal state of the environment when placed in the environment, the predetermined environment-dependent reference being comprised of at least a recorded sound/vibration image of the normal state of the environment in which the at least one portable unit is placed, the sensor system comprising an accelerometer/silicon crystal, microphone and temperature sensor, said accelerometer being triaxial, a processor member connected to the sensor system that compares signals received from the sensor system and said predetermined environment-dependent reference and that causes an alarm to be triggered upon determining an occurrence of a predetermined deviation of the signals received from the sensor system from the predetermined environment-dependent reference, a communication member of a unique identity connected to the processor member for wireless communication at least upon the triggering of the alarm signal, and a positioning member connected to the processor member that indicates, at least upon the triggering of an alarm signal, the position of said unit, and a memory member connected to the processor member via a distributed computer network, the memory member storing said predetermined reference for dynamic and interactive update and development for different purposes by maneuvering via fixed and/or mobile telephony and/or radio and/or computer unit.
