Safety device and method for using a safety device
First Claim
1. A security device comprising:
- sensors for checking whether the security device is in an undamaged state and checking for a presence of a specified support of the security device;
the sensors configured to detect at least one of material properties of the support and the security device and generate a signal for the at least one of the material properties; and
wherein the security device is coupled to an electronic system that is configured to compare an actual value of the signal with a predetermined target value and trigger an action upon a deviation of the actual value from the predetermined target value.

Abstract
The invention relates to a security device with sensors for checking whether the security device (1) is in an undamaged state and checking for the presence of a specified support (9) of the security device (1), said support (9) being an object, in particular a mechanical or electronic component, characterized in that the sensors detect movements and/or accelerations of the security device (1) relative to the support (9) and/or material properties of the support (9) and/or of the security device (1) and are connected to an electronic system (3) for signal evaluation. In a method for using such a security device (1) the state of the security device (1) and the presence of a specified support (9) are ascertained multiple times and in different ways, wherein signals are used which are obtained as actual values and which are compared with specified target values in an electronic system (3). An action is triggered upon a deviation of at least one of the actual values from the target values.

14. A method for determining whether a security device is in an undamaged state, the method comprising:
-
sensing for a first time whether the security device has been removed from a support associated with the security device; sensing for a second time whether the security device has been removed from the support associated with the security device, the sensing for a second time step comprising at least a different sensed measurement than the first sense; wherein at least one of the steps of sensing for the first and second times includes detecting at least one of material properties of the support and the security device; and wherein signals are used which are obtained as actual values and which are compared in an electronic system with predetermined target values, and an action is triggered upon a deviation of at least one of the actual values from the target values. - View Dependent Claims (15, 16, 17)
