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.

Abstract: A lock mechanism for locking at least one door of a container in a closed position includes a housing, at least one lock member at least partially enclosed within the housing, the at least one lock member comprising a first lock member configured to engage a first portion of a container to lock at least one container door in a closed position, and a latching mechanism coupled to the at least one lock member. The latching mechanism includes a fluid chamber configured to hold a fluid, a piston slidably housed within the fluid chamber, and a valve coupled to the fluid chamber and configured to be in one of two states, the two states including an open state where fluid can flow through the valve in two directions to allow the piston to be moved in two directions, and a closed state where fluid is inhibited from flowing through the valve in at least one direction to prevent the piston from moving in at least one direction.

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.

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.

Abstract: A system for sensing the security of a container includes a housing, at least two lock members coupled to the housing, the lock members configured to couple to first and second portions of the container to lock at least one container door in a closed position, a signal generator configured to generate a first signal and couple the first signal to the first portion of the container, the generated first signal having a known profile, and a lock controller configured to cause the signal generator to generate the first signal upon occurrence of a trigger event.
