摘要 |
The unauthorized separation of a second member such as a door with respect to a first member affixed to a computer frame and the subsequent replacement of the initial position of the door creates a change of state of a square loop magnetic member integral with the computer frame. This change of state can be monitored from time to time to indicate an unauthorized opening of the door.
