A device for indicating that a latch has been opened or tampered with includes a base, a head and a body having a frangible section. The body connects the base and the head. In use, the device is inserted into a latch in the closed or latched position. The device is positioned such that opening or unlatching the latch breaks or otherwise severs the frangible section, thereby separating the base from the head.

An electronic bolt seal assembly for locking a hasp of a cargo container, the assembly comprising: a bolt member comprising a head and an elongate shank extending therefrom; a locking body with a housing comprising a cavity for engaging the shank of the bolt member such that during use in a locking configuration the locking body is operable to lock the shank to the locking body in response to axial displacement of the shank within the housing; an electronic module arranged at or adjacent the head in a housing, the electronic module having one or more tracking and communication devices and an electronic circuit to communicate the electronic bolt seal assembly's location to a remote communication center wherein the one or more sensors further comprise an accelerometer for sensing movement and orientation of the bolt member.

A locking system and method for a movable freight container door comprises an electronic module and a mechanical lock element. The mechanical lock element comprises a shaft, at least of portion of which is configured to be inserted through an aperture in the electronic module, across a door handle retention region, and into a cavity in the electronic module. The shaft is securely retained in the electronic module by moving a lock mechanism to a locked position. At least one magnetic field sensor in the electronic module is used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the shaft. A wireless communication component in the electronic module wirelessly transmits magnetic field sensor information.

A rotary latch mechanism for releasably securing a first structure relative to a second structure. The rotary latch mechanism includes a housing adapted to be attached to the first structure, an actuator assembly coupled to the housing, a linkage coupled to the actuator assembly and arranged for movement along the housing with movement of the actuator assembly, and a bolt coupled to the housing and to the linkage, the bolt arranged for pivotal movement relative to the housing with movement of the linkage. The bolt is adapted to move between a latched position engaged with the second structure to secure the first structure relative to the second structure and an unlatched position spaced apart from the second structure to allow movement of the first structure relative to the second structure.

An insertion pin includes a pin member on which a circuit board, an inspection antenna, and an inspection chip are mounted. The circuit board includes a main circuit, a main chip, and an inspection circuit set in an open-circuit condition with respect to the inspection antenna and the inspection chip. A lock base includes a main antenna matching the main chip. When the lock base and the pin member are combined and locked together, the main chip is electrically connected with the main antenna to emit a first signal for monitoring with an identification device, and the inspection circuit is electrically connectable with the inspection chip and the inspection antenna to emit a second signal to allow a mobile phone to carry out quality control to determine if the first signal is in normal operation. Cutting off the insertion pin terminates both the first and second signals.

An electronic access system and method utilizes a modular latch system and method. The modular latch system and method include a reader module and latch module. The reader module includes a user interface with one or more readers or devices for receiving input from a user, and sending the input to a controller. The latch module is configured for mounting to a closure that provides access to the secure area. The latch module can be operated in a stand-alone mode while detached from the reader module. Alternatively, the latch module can be releasably engaged to the reader module and operated in an assembled mode. The modular system and method allow for engagement of the reader module to the latch module, disengagement of the reader module from the latch module, and engagement of an alternate reader module to the latch module for retrofitting the reader module with the alternate reader module.
