Abstract

A device for the tracking of an object is presented. The device comprising a wireless communication unit for the transmission of data via a wireless communications network, a measuring device, and a controller, wherein the wireless communication unit is controlled via the controller and wherein the measuring device is connected to the controller. The invention provides based on the measuring device the detection of a first transportation status, in which the device is located inside an aircraft or is in the state of flight. The detection of the transportation status of the device by the measuring device in an aircraft or in flight offers the opportunity to control other features of the device, in particular in regard to the wireless communication unit, in such manner as not to interfere with the electronic controls of an aircraft.

3. The apparatus of claim 1, wherein the wireless communication unit is deactivated when the first transportation status is detected, so that in the first transportation status no radio signals are emitted by the wireless communication unit.

4. The apparatus of claim 1, wherein the wireless communication unit, the measuring device, and the controller are designed as an integrated module, the integrated module comprising an independent power supply.

5. The apparatus of claim 4, wherein the integrated module comprises an independent power supply.

6. The apparatus of claim 4, wherein the integrated module comprises a sensor, the sensor being connected to the measuring device.

7. The apparatus of claim 1, wherein the measuring device is connected to an altitude sensor.

8. The apparatus of claim 1, wherein the measuring device is connected to a motion sensor.

9. The apparatus of claim 1, wherein the measuring device is connected to at least one vibration sensor.

10. The apparatus of claim 1, wherein the measuring device is connected to at least one ultrasound sensor.

11. The apparatus of claim 1, further comprising:

a receiver configured for a global positioning system (GPS) and configured to receive a signal from the global positioning system.

12. The apparatus of claim 11, wherein the measuring device is configured to detect a strength of the signal from the global positioning system and configured to use the strength of the signal to identify the first transportation status.

13. The apparatus of claim 11, wherein the global positioning system determines information, the information comprising a momentary position, a speed of the object, or both.

14. The apparatus of claim 13, wherein the information is forwarded via the wireless communication unit.

15. The apparatus of claim 1, wherein an additional transportation status is detected via the measuring device, and wherein in the additional transportation status, the object is in motion and is not located inside the aircraft.

16. The apparatus of claim 1, wherein an additional transportation status is detected via the measuring device, and wherein in the additional transportation status, the object is not located inside an aircraft and is not in motion.

17. The apparatus of claim 1, wherein an absence of the first transportation status is detected only if at least two independent signals indicate the absence of the first transportation status.

18. The apparatus of claim 17, wherein the at least two independent signals are selected from a group consisting of a global positioning system (GPS) signal strength, a GPS-determined speed signal, a vibration signal, and an air pressure signal.

19. The apparatus of claim 1, wherein the wireless communication unit operates based on the Global System for Mobile communications (GSM) standard.

20. The apparatus of claim 1, wherein the apparatus is installed on cargo, the cargo being for transportation inside an aircraft.

21. The apparatus of claim 20, wherein the cargo comprises a United Load Device container.

22. The apparatus of claim 20, wherein the cargo comprises an engine shipping cradle.

23. The apparatus of claim 1, wherein the apparatus is installed on an aircraft engine.

24. A method for the control of an apparatus for the tracking of an object, the method comprising:

obtaining a first measured value with a measuring device;

comparing the first measured value with a first predefined threshold value; and

activating a wireless communication unit based on results of comparing the first measured value.

25. The method of claim 24, wherein the apparatus for the tracking of the object comprises:

the wireless communication unit, the wireless communication unit being configured to transmit data via a wireless network;

the measuring device, the measuring device being configured to detect a first transportation status of the object, wherein in the first transportation status, the object is located inside an aircraft or is in flight; and

a controller configured to control the wireless communication unit, the measuring device being connected to the controller.

26. The method of claim 24, further comprising:

deactivating the wireless communication unit during a standard mode.

27. The method of claim 26, wherein in the standard mode, obtaining and comparing are performed after a defined time window has expired.

28. The method of claim 24, wherein obtaining, comparing, and activating are performed in response to a sensor signal.

29. The method of claim 28, wherein the sensor signal comprises a motion sensor signal.

30. The method of claim 24, wherein the measured value comprises the signal strength of a received global positioning system (GPS) signal.

31. The method of claim 30, further comprising:

detecting a first transportation status of the object when an amplitude of the received GPS signal drops below the first predefined threshold value.

32. The method of claim 30, further comprising:

detecting a first transportation status of the object when the received GPS signal does not allow the detection of a speed of the object.

33. The method of claim 30, further comprising:

detecting a first transportation status of the object when a speed of the object determined via the received GPS signal is greater than the first predefined threshold value.

34. The method of claim 30, further comprising:

activating the wireless communication unit in a second transportation status; and

detecting the second transportation status only if a speed of the object determined via the the received GPS signal is below the first predefined threshold value, and the amplitude of the received GPS signal is below a second predefined threshold value.

35. The method of claim 34, further comprising:

activating the wireless communication unit in a third transportation status; and

detecting the third transportation status only if the speed of the object is at least close to zero.
