Abstract
A tamper-indicating assembly includes a container formed by a plurality of walls and a door mechanically coupled to at least one of the walls via a hinge. At least one cable extends at least partially through the hinge between the door and the at least one wall. The cable transmits a signal, and the assembly can identify potential tamper events related to opening and closing of the door based on changes in properties of the transmitted signal. Techniques for forming the assembly are also described.
Claims20
A tamper-indicating assembly comprising:
- a plurality of walls;
- a door, wherein the plurality of walls and the door define a cavity;
- at least one hinge configured to mechanically couple the door to at least one wall of the plurality of walls;
- and
- at least one cable extending at least partially through the hinge between the door and the at least one wall.
A method comprising:
- mechanically coupling a door to at least one wall of a plurality of walls via at least one hinge, wherein the plurality of walls and the door define a cavity;
- and
- positioning at least one cable such that the at least one cable extends at least partially through the hinge between the door and the at least one wall.
A method comprising:
- detecting a change in at least one characteristic of a signal transmitted through at least one cable;
- and
- detecting a possible tamper event based on detecting the change in the at least one characteristic of the signal, wherein the at least one cable extends at least partially through a hinge and wherein the change in the at least one property of the signal corresponds to rotation of the hinge.
