Patent ID: 8047142

Claim:
A protection method for protecting valuables, the valuables being enclosed in an internal enclosure, the internal enclosure being enclosed in an external enclosure, and a misuse protection device for the valuables being triggered in the event of an unauthorized manipulation on the external enclosure, the method comprising the steps of: enclosing the internal enclosure in the external enclosure, and forming a tightly sealed pressure chamber impinged by an initial pressure in the external enclosure, defining a setpoint pressure that deviates from the ambient pressure; using pressure-changing means, generating the setpoint pressure in the pressure chamber, at least one of (a) changing the setpoint pressure in the event of a change of the ambient pressure and (b) changing the setpoint pressure in the event of a change of the ambient temperature, and monitoring the pressure in the pressure chamber using a pressure sensor, wherein a triggering device is controlled by the pressure sensor and triggers the misuse protection device when the pressure in the pressure chamber deviates from the setpoint pressure by more than a tolerance pressure value.
