Appl. No.:

12/825195

Inventors:

David R. Powers - La Jolla CA, US
Donald H. Warf - Dulles VA, US
Daniel Bertuna - Fairfax Station VA, US

Assignee:

Cubic Corporation - San Diego CA

International Classification:

E05B 47/00

US Classification:

307 66, 307 64

Abstract:

A lock mechanism to lock at least one door of a container in a closed position includes a housing enclosing at least a portion of the lock mechanism, and a lock circuit at least partially enclosed within the housing. The lock circuit includes a main power supply, a backup power supply, a plurality of subsystems, and a lock controller coupled to the main power supply and the backup power supply. The lock controller is configured to receive commands related to operation of the lock mechanism, determine a battery level remaining in the main power supply, determine if the remaining battery level is below a threshold level, and cause the lock circuit to enter a lower power mode upon determining that the remaining battery level is below the threshold level. When in the lower power mode, at least a portion of the subsystems of the lock circuit are not powered, the lock controller receives power from the main power supply, and the lock controller monitors an interface to detect a command to unlock the lock mechanism.

US Classification:

340 564, 70 14, 70 56

Abstract:

A system for operating a container lock mechanism includes a housing, at least two lock members, the two lock members including a first lock member configured to engage a first portion of a container and a second lock member configured to engage a second portion of the container to mount the container lock mechanism outside of the container and lock at least one container door in a closed position. The system further includes a latching mechanism coupled to the first and second lock members, a lock circuit at least partially enclosed within the housing. The lock circuit includes a first memory, a wireless module configured to receive a wireless signal and a lock controller coupled to the first memory, the wireless module and the latching mechanism and configured to receive commands related to operation of the lock mechanism, at least a portion of the commands being part of the wireless signal, to cause the latching mechanism to resist having the first and second lock members be disengaged from the first and second portions of the container when the first and second lock members are engaged to the first and second portions of the container, thereby locking the at least one container door in response to the received commands, and a battery coupled to the lock circuit and configured to provide electrical power to at least a portion of the lock circuit.

Abstract:

A lock mechanism for locking at least one door of a container in a closed position includes first and second members slidably coupled to each other to move relative to each other, a latching mechanism configured to prevent the two members from moving relative to each other in at least one direction when the latching mechanism is in a locked state, and first and second lock members, each of the lock members including a first end and a second end. The first ends of the first and second lock members protrude through the body. The second end of the first lock member is coupled to the first member of the locking mechanism and the second end of the second lock member being coupled to the second member of the locking mechanism. The first ends of the first and second lock members are configured to engage portions of the container to lock the at least one container door in a closed position. The body is sized and disposed to support the first and second lock members to prevent rotation of the first and second lock members about points where the first and second lock members are attached to the first and second members of the latching mechanism.

Abstract:

A system for monitoring chain of custody of contents of a container includes a lock mechanism configured to lock at least one door of the container in a closed position, a housing enclosing at least a portion of the lock mechanism, and a lock circuit at least partially enclosed within the housing. The lock circuit includes a memory, a lock controller, a wireless module configured to receive information from at least one sensor associated with the container, the information regarding at least one property of the contents of the container, wherein the wireless module is configured to store the information in memory, wherein at least one of the wireless module or the sensor is powered wirelessly, and a lock controller configured to receive commands related to operation of the lock mechanism, to monitor the stored information to identify a change of state of the at least one sensor, and to generate chain of custody data to be transmitted to a remote location via the wireless module. The chain of custody data includes at least two of sensor data, an authentication code associated with the sensor, and/or an authentication code associated with the lock mechanism.
