Abstract

A portable articulated arm coordinate measuring machine is provided having a base. A cover is rotatably coupled to the base to move between a closed position and an open position. A display is arranged within the cover. The display includes a screen surface, such as a touch sensitive screen surface, disposed on one side of the housing. The screen surface being adjacent the base in the closed position and disposed on an angle to the base in the open position.

Claims

1. A portable articulated arm coordinate measuring machine (AACMM), comprising:

a base;

a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

a measurement device attached to the first end;

an electronic circuit which receives the position signals from the transducers and provides data corresponding to a position of the measurement device;

a cover directly coupled to the base; and

a display arranged within the cover and electrically coupled to the electronic circuit, the display having a screen surface disposed on one side of the cover.

2. The AACMM of claim 1 wherein

the cover is movable between a closed position and an open position;

and

the screen surface is arranged adjacent the base in the closed position and disposed on an angle relative to the base in the open position.

3. The AACMM of claim 2 wherein the screen surface is arranged at an obtuse angle relative to the closed position when in the open position.

4. The AACMM of claim 2 further comprising at least one indicator coupled to the cover and arranged on a side opposite the screen surface.

5. The AACMM of claim 2 wherein the base includes a recessed area adjacent the cover, the cover being at least partially disposed in the recessed area in the closed position.

6. The AACMM of claim 2 further comprising a latch member disposed on one side of the cover, the latch member removably coupling the cover to the base when in the closed position, wherein the cover is rotationally coupled to the base by at least one hinge arranged on a side opposite the latch member.

7. The AACMM of claim 1 further comprising:

a controller disposed in the cover and operably coupled to the display, the controller coupled for communication with the electronic circuit.

8. The AACMM of claim 7 wherein the controller further includes at least one interface connection.

9. The AACMM of claim 1 wherein the display is a touch sensitive display.

10. The AACMM of claim 1 wherein the cover is coupled to rotate about a first axis and a second axis.

11. The AACMM of claim 1 wherein the base includes a handle portion disposed adjacent the cover.

12. A portable articulated arm coordinate measurement measuring machine (AACMM), comprising:

a base;

a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

a measurement device attached to the first end;

an electronic circuit which receives the position signals from the transducers and provides data corresponding to a position of the measurement device;

a display rotationally coupled to the base between a closed position and an open position, the display having a screen disposed on one side wherein the screen is adjacent the base in the closed position; and

a controller operably coupled to the display and coupled for communication to the electronic circuit.

13. The AACMM of claim 12 wherein the base includes a recess on one side, the display being rotationally coupled to the base within the recess.

14. The AACMM of claim 13 further comprising:

a battery electrically coupled to the electronic circuit; and

wherein the recess includes an opening sized to receive the battery.

15. The AACMM of claim 14 further comprising a cover disposed about the display and the controller, wherein the screen is arranged on a side of the cover that is positioned within the recess when the display is in the closed position.

16. The AACMM of claim 12 wherein the screen is a touch sensitive screen.

17. The AACMM of claim 16 further comprising at least one computer interface operably coupled to the controller, the at least one computer interface being coupled to the screen.

18. The AACMM of claim 12 wherein the base includes a handle on one side.

19. A portable articulated arm coordinate measurement measuring machine (AACMM), comprising:

a base;

a manually positionable articulated arm having opposed first and second ends, the arm being rotationally coupled to the base on the second end, the arm including a plurality of connected arm segments, each arm segment including at least one position transducer for producing a position signal;

a measurement device attached to the first end;

an electronic circuit which receives the position signals from the transducers and provides data corresponding to a position of the measurement device; and

a display coupled to the base and electrically coupled to the electronic circuit, the display configured to rotate between a closed position and an open operational position;

wherein the plurality of connected arm segments are configured to define a path of an outer periphery of travel of the measurement device, the path separated from the display by a gap distance when the display is in the open operational position.

20. The AACMM of claim 19 wherein the gap distance is greater than zero.

21. The AACMM of claim 20 wherein the display is coupled to the base to rotate about a first axis and a second axis.

22. The AACMM of claim 20 further comprising:

a controller operably coupled to the display and electrically coupled to the electronic circuit; and

wherein the controller includes a processor responsive to executable computer instructions for displaying data derived from the at least one position transducer on the display in response to a first signal from the display.

23. The AACMM of claim 22 wherein the controller is further responsive to transmitting a second signal to the electronic circuit in response to a third signal from the display.
