Patent ID: 7673513

Claim:
A sensor device for monitoring an acceleration of an object during a transportation, comprising: an acceleration sensor that is permanently connected to the object; and an RFID transceiver device connected to the acceleration sensor that non-contact couples electrical energy into the acceleration sensor and emits a radio signal based on a physical state of the acceleration sensor; wherein the acceleration sensor includes; a movable mass that deflects from a rest position as a function of the acceleration, a support frame that holds the movable mass, and an electrical conductor linked to the REID transceiver device that is irreversibly interrupted if the deflection of the movable mass exceeds a predetermined threshold value; and wherein the support frame comprises a sensor wall that is permanently connected to the electrical conductor and the movable mass is pressed against the sensor wall as a function of the acceleration to interrupt the electrical conductor if the pressure on the sensor wall exceeds a predetermined threshold value.
