Aircraft container tracking device
A wireless transmitter device that has a baseline ‘off’ status, turning its data transmission module ‘on’ only under certain specific circumstances, thus allowing the device to be used on aircraft without concern of the device activating and transmitting location data that might interfere with the aircraft navigation and/or communication systems. The data transmission module may be turned on manually (i.e., manual activation), may be activated based on time (i.e., time-based activation), or may be activated based on motion (i.e., motion-based activation). Activation of the data transmission module occurs only after it has been determined that it is safe to activate the module(s), for example, if no motion of the device has been sensed for a predetermined period of time. Only after the device has assuredly determined that the aircraft is in a mode where data transmission is allowed (e.g., not in flight) is the data transmission module activated.
1. A wireless tracking device comprising at least one of an RF communication module and/or a cellular communication module, and a sensor array comprising a motion sensor always in an ‘on’ sensing mode, a vision sensor and environmental sensor(s);
the vision sensor and environmental sensor(s) in a sensing ‘off’ mode until activated either manually, based on expiration of a timer, and/or based on movement above a threshold level, and
all of the communication modules in a data transmission ‘off’ mode if determined by the vision sensor and/or the environmental sensor(s) that the tracking device is inside an aircraft, and at least one of the communication modules in a data transmission ‘on’ mode if determined by the motion sensor, vision sensor and/or the environmental sensor(s) that the device is outside the aircraft where communication is allowed.
2. The wireless tracking device of claim 1 further comprising a GPS positioning element.
3. The wireless tracking device of claim 1 , comprising the RF communication module and the cellular communication module.
4. The wireless tracking device of claim 1 , wherein the communication module is activated manually by an operator.
5. The wireless tracking device of claim 1 , wherein the communication module is activated by a time-based algorithm.
6. The wireless tracking device of claim 1 , wherein the communication module is activated by a movement-based algorithm.
7. The wireless tracking device of claim 1 , wherein the communication module is activated based on a known or estimated business event.
8. A method for a wireless tracking device, comprising:
initially having any RF communication module and any cellular communication module of the tracking device deactivated and a motion sensor of the tracking device is activated, each of the RF communication module and the cellular communication module configured to transmit data to an appropriate receiver;
sensing movement of the tracking device with the motion sensor of the tracking device;
if the sensed movement is above a threshold level or after a timer has expired if there is no sensed movement, activating a vision sensor of the tracking device and environmental sensor(s) of the tracking device;
further sensing movement and location of the tracking device with the motion sensor, the vision sensor and/or the environmental sensor(s); and
if the sensed further movement and location is not inside an aircraft, activating the RF communication module and the cellular communication module to transmit data when the sensed further movement is above the threshold level or after the timer has expired, and if the sensed further movement and location is inside an aircraft, the RF communication module and the cellular communication module remaining deactivated.
