A freight tracking system uses a tracking device hidden in the taillight of a vehicle and a remote device located somewhere else on the vehicle. The remote device determines the position of the vehicle using information received from global navigation system satellites and communicates this wirelessly to the tracking device using a mesh network. The tracking device comprises a 9-axis IMU (inertial measurement unit) that uses a fusion filter and a calculation involving digital quaternions to determine inertial information. The vehicle position is compared to geographic boundary information to determine if the vehicle might have gone outside of geographic boundaries. If so, a geofencing alarm is triggered. The device has a tampering detector to ensure that the device is not opened. The alarms, vehicle position, and time information can be communicated to an internet-connected database using a cellular wireless device.

A latch assembly comprising: a latch operable to adopt a latched condition and an unlatched condition; a magnet imparting a magnetic field; a sensor adapted to sense the magnetic field; the latch, magnet and sensor being configured such that a change in the condition of the latch effects a variance in the magnetic field sensed by the sensor to distinguish between the latched condition and the unlatched condition, wherein the latch includes a latch member that is moveable relative to both the sensor and the magnet when the latch changes from the unlatched condition to the latched condition and the proximity of the latch member to the magnet changes the strength of the magnetic field sensed by the sensor.

An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.

A lock system and method for alerting a user or other entity that a lock has been or is being tampered with is disclosed. The lock includes at least one enhanced security pin that is electrically isolated from the rest of the lock. When the lock picker attempts to pick the lock a portion of the enhanced security pin contacts either the plug or the outer casing of the lock to complete a circuit with an alert component. The completion of the circuit causes the alert component to generate an alert signal that can be observed by the user or other entity.

A door lock detection system is disclosed. The system includes a magnet flexibly attached to a strike plate. The strike plate includes an opening. The magnet extends across the opening of the strike plate in a first orientation when a bolt does not extend into the opening of the strike plate. The magnet is configured to be deflected from the first orientation to a second orientation, distinct from the first orientation, in response to the bolt being extended into the opening of the strike plate. The system includes a magnetometer configured to detect one or more magnetic fields of the magnet that is flexibly attached to the strike plate in the first orientation and in the second orientation.

A locking system and method for a movable freight container comprises an electronic module with a shaft that goes into a cavity in a mechanical lock module. The shaft is securely retained in the cavity by a lock mechanism in the mechanical lock module by moving the lock mechanism to a locked position. A plurality of magnetic field sensors in the shaft are used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the lock mechanism to confirm continuous time insertion of the shaft in the cavity. A wireless communication component in the electronic module wirelessly transmits an alarm signal if the magnetic field sensors detect an unexpected interruption in at least one of the continuous time shaft position magnetic sensor readings.
