Abstract

A power tool control system includes a non-contact measurement and alignment device operative with the power tool and enabled to establish various readings, such as power tool settings. A graphical user interface communicatively coupled with the non-contact measurement and alignment device enables user control over and display of the readings from the non-contact measurement and alignment device. Related table saw assemblies are disclosed in which, for example, a bevel angle of a saw blade may be adjusted.

Claims

1. A power tool control system, comprising:

a non-contact measurement and alignment device operative with a power tool for determining power tool settings;

a graphical user interface communicatively coupled with the non-contact measurement and alignment device, the graphical user interface for user operation of said power tool for indicating at least two of a power tool setting; and

a display menu which logically relates folders providing power tool setting options and readouts of current settings.

2. The power tool control system of claim 1, wherein the non-contact measurement and alignment device is integrated with the power tool.

3. The power tool control system of claim 1, wherein the non-contact measurement and alignment device further comprises a laser source.

4. The power tool control system of claim 3, wherein the laser source is a laser light indicia and reading assembly.

5. The power tool control system of claim 1, wherein the non-contact measurement and alignment device includes a kerf correction.

6. The power tool control system of claim 1, wherein the non-contact measurement and alignment device is a modular non-contact measurement and alignment device.

7. The power tool control system of claim 1, further comprising a computing system communicatively coupled with the non-contact measurement and alignment device and the graphical user interface.

8. A table saw assembly, comprising:

a frame coupled with a table, the table having an aperture;

a bevel adjustment assembly coupled with the table and a saw assembly including a saw blade, the bevel adjustment assembly for establishing a beveled angle setting for the saw blade which extends through the aperture;

a bevel indication assembly coupled with the bevel adjustment assembly, the bevel indication assembly further comprising, a non-contact measurement and alignment device operative with the bevel adjustment assembly for determining saw blade settings; and

an indicator operationally engaged by the non-contact measurement and alignment device, the indicator for indicating the beveled angle setting of the saw blade, wherein the bevel indication assembly provides a visual marker indicating the beveled angle setting of the saw blade.

9. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device is integrated with the table.

10. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device further comprises a laser source.

11. The table saw assembly of claim 10, wherein the laser source is a laser light indicia and reading assembly.

12. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device includes a kerf correction.

13. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device is a modular non-contact measurement and alignment device.

14. The table saw assembly of claim 8, further comprising a graphical user interface communicatively coupled with the non-contact measurement and alignment device.

15. The table saw assembly of claim 8, further comprising a computing system communicatively coupled with the non-contact measurement and alignment device and the graphical user interface.

16. The table saw assembly of claim 8, wherein the bevel adjustment assembly is configured to rotate proportionately to the saw blade.

17. The table saw assembly of claim 8, wherein the bevel adjustment assembly includes an adjustment flange.

18. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device is mounted to the bevel adjustment assembly.

19. The table saw assembly of claim 8, wherein the visual marker includes a scale for indicating the beveled angle.

20. The table saw assembly of claim 8, wherein the non-contact measurement and alignment device includes an imaging device.

21. The table saw assembly of claim 20, wherein:

the imaging device includes a plurality of sensors, each of the sensors representing an angular position for the saw blade; and

the visual marker is configured to activate one of the plurality of sensors which corresponds to a beveled angle of the saw blade.

22. The table saw assembly of claim 20, further comprising a light emitter coupled to the imaging device, the light emitter being configured to emit light in a direction of the visual marker and thereby reflect light onto the imaging device.
