Patent ID: 8344881

Claim:
A system for providing cascaded tamper detection comprising: a plurality of items in a housing, in which the housing is a single container, a plurality of sensors (Ss) and a plurality of signal generators (Ms) arranged in alternating sequence of S, M, S, M, and so on, and each adjacent S and M forming a tamper detector of a respective item in the housing, wherein a tamper detector of one item notifies another tamper detector of another item of an occurrence of a tamper event in a cascaded manner; wherein the S of one tamper detector detects a change in one of a magnetic field, an electric field, light energy, sound energy, vibration energy, and heat energy resulting from displacement of a respective item or a tampering source of field or energy, and notifies another tamper detector by transmitting via the M one of a magnetic pulse, an electric pulse, a light pulse, a sound pulse, a vibration pulse, or a heat pulse respective of the type of field or energy detectable by each S.
