Abstract

A data reading system is mountable onto a material transport device having a first section, a primary power supply and a second section movable with respect to the first section. The data reading system comprises a data reader disposed on the second section of the material transport device, the data reader comprising a power source and an induction power receiving unit. The data reading system also comprises an induction power transmission unit disposed on the first section of the material transport device and connected to the primary power supply of the material transport device. The induction power receiving unit is located proximate the induction power transmission unit when the second section is disposed in a given position with respect to the first section, whereby the induction power transmission unit transmits power to the induction power receiving unit for charging the power source of the data reader.

Claims

1. A data reading system mountable onto a material transport device having a first section, a primary power supply mounted on the first section, and a second section movable with respect to the first section, the data reading system comprising:

a data reader disposed on the second section of the material transport device, the data reader comprising a power source and an induction power receiving unit; and

an induction power transmission unit disposed on the first section of the material transport device and connected to the primary power supply of the material transport device;

wherein the induction power receiving unit is located proximate the induction power transmission unit when the second section is disposed in a given position with respect to the first section, whereby the induction power transmission unit transmits power to the induction power receiving unit for charging the power source of the data reader.

2. A system as set forth in claim 1, wherein the material transport device is selected from the group consisting of a forklift, a material lift, a material transfer cart, and a material mover.

3. A system as set forth in claim 1, wherein the material transport device is a vehicle.

4. A system as set forth in claim 1, wherein the first section of the material transport device is a mast and the second section of the material transport device moves along the mast.

5. A system as set forth in claim 1, wherein the power source comprises a rechargeable device.

6. A system as set forth in claim 1, wherein the data reader further comprises an RFID interrogator.

7. A system as set forth in claim 1, wherein the data reader further comprises an optical code reader.

8. A method for use with an apparatus mounted on a movable member of an article transport device, wherein the article transport device comprises a main power supply and the apparatus comprises a local power source, the method comprising:

providing an induction power transmission unit electrically connected to the main power supply; and

providing an induction receiving unit electrically connected to the local power supply of the apparatus such that, when the induction power receiving unit is in a given position proximate the induction power transmission unit, power from the induction power transmitting unit is transmitted to the induction power receiving unit by induction to thereby charge the local power source of the apparatus.

9. A method as set forth in claim 8, further comprising:

providing the apparatus and mounting the apparatus on the movable member of the article transport device.

10. A method as set forth in claim 9, wherein the apparatus is a data reader.

11. A method as set forth in claim 10, wherein the data reader comprises an RFID interrogator.

12. A method as set forth in claim 10, wherein the data reader comprises an optical code reader.

13. A method as set forth in claim 8, further comprising:

providing a wireless communications link between the apparatus and a host.

14. A method as set forth in claim 13, wherein the host is a computer mounted on the article transport device.

15. A method as set forth in claim 8, wherein the article transport device is a vehicle.

16. A method as set forth in claim 15, wherein the vehicle is a forklift having forks to lift articles, and the movable member moves in unison with the forks.

17. A method as set forth in claim 8, wherein the local power source comprises a rechargeable battery.

18. A method as set forth in claim 8, further comprising:

moving the movable member such that the induction power receiving unit is in a given position proximate the induction power transmission unit;

transmitting power from the induction power transmitting unit to the induction power receiving unit by induction when the induction power receiving unit is in the given position; and

charging the local power source of the apparatus using the power transmitted by induction.

19. A material transport machine comprising:

a first section,

a primary power supply mounted on the first section, and

a second section movable with respect to the first section;

an electric powered apparatus mounted on the second section, the electric powered apparatus comprising a chargeable power source;

an induction power transmission unit attached to the first section and conductively connected to the primary power supply such that the primary power supply supplies power to the induction power transmission unit; and

an induction power receiving unit attached to the second section and conductively connected to the power source of the electric powered apparatus, wherein the induction power receiving unit is located proximate the induction power transmission unit when the second section is disposed in a given position with respect to the first section, whereby the induction power transmission unit transmits power to the induction power receiving unit in said given position for charging the power source of the electric powered apparatus.

20. A machine as set forth in claim 19, wherein the machine is selected from the group consisting of a forklift, a material lift, a material transfer cart, and a material mover.

21. A machine as set forth in claim 19, wherein the material transport machine is a vehicle.

22. A machine as set forth in claim 19, wherein the first section of the material transport machine comprises a mast and the second section of the material transport device moves along the mast.

23. A machine as set forth in claim 19, wherein the power source comprises a rechargeable battery.

24. A machine as set forth in claim 19, wherein the apparatus is a data reader.

25. A machine as set forth in claim 24, wherein the data reader comprises an RFID interrogator.

26. A machine as set forth in claim 24, wherein the data reader comprises an optical code reader.

27. A machine as set forth in claim 19, further comprising:

a computer; and

a wireless communication link between the computer and the electric powered apparatus.

28. A machine as set forth in claim 19, wherein the first and second sections of the material transport machine are physically connected during normal operation.

29. A machine as set forth in claim 19, wherein the material transport device is designed to move bulk items.
