Abstract

A method for positioning a handheld tool is disclosed. In one embodiment, information is received at a handheld tool for positioning a working end of the handheld tool at a desired position. Information is also received at the handheld tool for aligning the handheld tools at the desired position.

Claims

1. A method for positioning and orienting a handheld tool comprising:

receiving, at said handheld tool from an entity that is not within a structure that said handheld tool will perform a task on, information for positioning a working end of said handheld tool at a desired position with respect to said structure, wherein the desired position is different than a current position of said handheld tool;

displaying, on said handheld tool, at least one cue for positioning said working end of said handheld tool at said desired position;

receiving, at said handheld tool from said entity, instructions for orienting said handheld tool at said desired position to a desired orientation, wherein the desired orientation is different than a current orientation of said handheld tool; and

displaying, on said handheld tool, at least one cue for aligning said handheld tool to said desired orientation.

2. The method of claim 1 further comprising:

receiving at said handheld tool an operating parameter of said handheld tool to perform a task.

3. The method of claim 1 further comprising:

automatically detecting by said handheld tool an identification of a consumable item coupled with said handheld tool; and

determining an offset of a working end of said consumable item relative to an antenna of a Global Navigation Satellite System (GNSS) antenna coupled with said handheld tool.

4. The method of claim 1 further comprising:

communicatively coupling said handheld tool with a positioning infrastructure;

receiving by said positioning infrastructure a report conveying said desired position and orientation;

wirelessly sending said desired position and orientation to said handheld tool; and

displaying said desired position and orientation using a user interface coupled with said handheld tool.

5. The method of claim 4 wherein said positioning infrastructure comprises a separate device from said handheld tool, said method further comprising:

determining the position of said positioning infrastructure;

determining the position and orientation of said handheld tool and said desired position and orientation relative to said positioning infrastructure; and

generating by said positioning infrastructure the information for positioning said working end of said handheld tool to said desired position and the instructions for orienting said handheld tool at said desired position to said desired orientation.

6. The method of claim 1 further comprising:

displaying an image which conveys said desired position and orientation of said working end of said handheld tool.

7. The method of claim 6 further comprising:

projecting said image using a set of heads-up display (HUD) glasses.

8. The method of claim 1 further comprising:

displaying the location of said structure proximate to said desired position.

9. A handheld tool comprising:

a data receiver configured to receive, from an entity that is not within a structure that said handheld tool will perform a task on, positioning information describing a desired position of a working end of said handheld tool to perform said task on said structure, wherein the desired position is different than a current position of said handheld tool, said data receiver further configured to receive a set of alignment data for orienting said handheld tool when said working end is situated at said desired position;

a display integrated with said handheld tool and configured to display, on said handheld tool, at least one cue for positioning said working end of said handheld tool at said desired position and at least one cue for orienting said handheld tool at said desired position to a desired orientation, wherein the desired orientation is different than a current orientation of said handheld tool; and

a tool position detector configured to provide data verifying that said working end of said tool is located at said desired position and that said handheld tool is oriented in accordance with said alignment data.

10. The handheld tool of claim 9 wherein said data receiver is further configured to receive an operating parameter of said handheld tool to perform a task.

11. The handheld tool of claim 9 further comprising:

a tool position detector comprising at least one sensor for automatically detecting an identification of a consumable item coupled with said handheld tool; and

a Global Navigation Satellite System (GNSS) position determination device, and wherein said tool position detector is configured to determine an offset of a working end of said consumable item relative to an antenna of said GNSS position determination device.

12. The handheld tool of claim 9 further comprising:

a wireless communication transceiver for communicatively coupling said handheld tool with a positioning infrastructure and wherein said positioning infrastructure wirelessly conveys said desired position and orientation to said handheld tool; and

a user interface for displaying said desired position and orientation.

13. The handheld tool of claim 12 wherein said positioning infrastructure comprises a separate device from said handheld tool, and wherein said positioning infrastructure is configured to determine its position, determine the position of said handheld tool and said desired position relative to said positioning infrastructure, and to generate the positioning information describing said desired position of a working end of said handheld tool and said set of alignment data for orienting said handheld tool based upon at least one report received by said positioning infrastructure.

14. The handheld tool of claim 9 further comprising:

a user interface comprising a set of heads-up display (HUD) glasses upon which an image which conveys said desired position and orientation of the working end of said handheld tool.

15. The handheld tool of claim 9 further comprising:

a user interface used to display the location of said structure proximate to said desired position.

16. A system for providing positioning information to handheld tools, said system comprising:

an information management system for accessing task data for a site;

a handheld tool comprising;

a user interface integrated with said handheld tool; and

a tool position detector configured to determine a position of a working end of said handheld tool and an orientation of said handheld tool; and

a positioning infrastructure wirelessly coupled with said information management system and configured to correlate the task data with said position of said working end of said handheld tool and to generate at least one cue for positioning said working end of said handheld tool at a desired position of said site and to generate at least one cue for orienting said handheld tool at said desired position to a desired orientation wherein the desired orientation is different than a current orientation of said handheld tool, wherein the desired position is different than a current position of said handheld tool, and wherein said user interface is configured to display, on said handheld tool, at least one cue for positioning a working end of said handheld tool at said desired position of said site and said at least one cue for orienting said handheld tool at said desired position to said desired orientation.

17. The system of claim 16 wherein said user interface further comprises a set of heads-up display (HUD) glasses upon which an image which conveys said desired position and orientation of said working end of said handheld tool.

18. The system of claim 16 wherein said positioning infrastructure comprises a device separate from said handheld tool.

19. The system of claim 16 further comprising:

a reporting source comprising a wireless transmitter and configured to report task data generated by said handheld tool to said information management system.
