Abstract

A method of operating an articulated arm CMM is provided. Instructions for the CMM can be inputted to the CMM arm by an action chosen from the group consisting of placing the arm in a predefined position and moving the arm in a predefined manner.

Claims

1. A method of operating a device for coordinate data acquisition, the device having a measuring portion, comprising inputting an instruction to the device for coordinate data acquisition during continuous use of the device for coordinate data acquisition by an action chosen from the group consisting of placing the measuring portion of the device in a predefined position and moving the measuring portion of the device in a predefined manner.

2. The method of claim 1, wherein the step of inputting is performed without actuating any buttons, levers, dials, or other traditional actuation devices.

3. The method of claim 1, wherein the measuring portion of the device can be placed into a generally retracted position and further comprising the step of placing the measuring portion of the device into a generally retracted position to cause the device to enter a sleep mode.

4. The method of claim 3, further comprising the step of the device entering a sleep mode automatically after the step of placing the measuring portion of the device into a generally retracted position.

5. The method of claim 1, further comprising the step of awakening the device from a sleep mode by rapidly moving the measuring portion of the device.

6. The method of claim 1, further comprising the step of instructing the device to increase its measurement in frequency or accuracy by moving the measuring portion slowly.

7. The method of claim 1, wherein the device for coordinate data acquisition comprises an articulated arm coordinate measuring machine.

8. The method of claim 1, wherein the measuring portion comprises a laser scanner.

9. The method of claim 1, wherein the measuring portion comprises a touch probe.

10. The method of claim 1, wherein the device is portable.

11. A device for coordinate data acquisition comprising a measuring portion and being configured to receive instructions during continuous use of the device for coordinate data acquisition from actions chosen from the group consisting of placing the measuring portion in a predefined position and moving the measuring portion in a predefined manner.

12. The device of claim 11, wherein the device is configured to receive instructions without the use of any buttons, levers, dials, or other traditional actuation devices.

13. The device of claim 11, wherein the measuring portion of the device can be placed into a generally retracted position, and wherein the device is configured to automatically enter a sleep mode when the measuring portion of the device is placed into the generally retracted position.

14. The device of claim 11, wherein the device is configured to automatically awaken from a sleep mode upon rapid movement the measuring portion of the device.

15. The device of claim 11, wherein the device is configured to automatically increase its measurement frequency or accuracy when the measuring portion is moved slowly.

16. The device of claim 11, wherein the device for coordinate data acquisition comprises an articulated arm coordinate measuring machine.

17. The device of claim 11, wherein the measuring portion comprises a laser scanner.

18. The device of claim 11, wherein the measuring portion comprises a touch probe.

19. The device of claim 11, wherein the device is portable.
