Abstract: A portable safe for assembly with an apertured member includes a safe housing and a safe door. The safe housing has an internal cavity extending to an access port, and at least one opening configured to align with at least one aperture of the apertured member. The safe door is securable to the housing to substantially block the access port. The safe door includes a locking mechanism having at least one locking member secured in a housing engaging position when the locking mechanism is in a locked condition. The at least one locking member is movable to a housing disengaging position when the locking mechanism is in an unlocked condition. The safe door further includes a lock interface that is selectively operable to move the locking mechanism from the locked condition to the unlocked condition.

Abstract: A cargo alarm system includes a signal carrying device configured to be coupled between the cargo and a storage location. The signal carrying device provides a closeable loop alarm signal path on which an alarm signal is conducted between the storage location and the cargo. An alarm unit in signal communication with the signal carrying device generates the alarm signal and triggers an alert condition when the alarm signal path is disrupted.

Abstract: For a cargo alarm system cargo is secured to a storage location, such as, for example, a vehicle by coupling a signal carrying device between the storage location and the cargo. The signal carrying device, which may be, for example, a flexible electrically conducting tether, provides a closeable alarm signal loop between the storage location and the cargo. An alarm signal is transmitted on the signal carrying device and in turn the alarm signal is received on the signal carrying device. An alert signal is provided when the alarm signal is not received from the signal carrying device.
