Abstract

A hand held power tool assembly is disclosed. The assembly includes a hand held power saw having (i) a housing, (ii) a saw blade, (iii) a base having an opening through which the saw blade extends, and (iv) a motor positioned within the housing and configured to rotate the saw blade in a path of movement. The assembly further includes an imaging device attached to the base of the power saw, the imaging device being configured to generate data signals representative of a detected image. In addition, the assembly includes a display device attached to the housing of the power saw, the display device being configured to receive the data signals generated by the imaging device and generate a visible representation of the detected image.

Claims

1. A hand held power saw assembly, comprising:

a hand held power saw having (i) a housing, (ii) a saw blade, (iii) a base having an opening through which said saw blade extends, and (iv) a motor positioned within said housing and configured to rotate said saw blade in a path of movement;

an imaging device attached to said base of said power saw, said imaging device being configured to generate data signals representative of a detected image; and

a display device attached to said housing of said power saw, said display device being configured to receive said data signals generated by said imaging device and generate a visible representation of said detected image.

2. The assembly of claim 1, wherein:

said base includes a leading edge and a trailing edge,

said opening is interposed between said leading edge and said trailing edge, and

said imaging device is attached to said base at a location that is interposed between said leading edge and said opening.

3. The assembly of claim 1, wherein said imaging device includes a video camera attached to said base.

4. The assembly of claim 3, wherein said video camera includes a CCD (charge coupled device) camera.

5. The assembly of claim 1, wherein said display device includes an LCD (liquid crystal display) screen.

6. The assembly of claim 1, wherein:

said display device includes a display screen,

said display screen includes a leading edge and a trailing edge, and

said leading edge is positioned vertically above said trailing edge, whereby said display screen assumes a tilted orientation facing toward a rear of said hand held power tool.

7. The assembly of claim 1, wherein:

said display device includes a display screen, and

said display device is configured to generate said visible representation of said detected image on said display screen.

8. A hand held power tool assembly, comprising:

a hand held power tool having (i) a housing, (ii) a working element, and (iii) a motor positioned within said housing and configured to move said working element in a path of movement;

an imaging device supported by said hand held power tool, said imaging device being configured to generate data signals representative of a detected image; and

a display device supported by said hand held power tool, said display device being configured to receive said data signals generated by said imaging device and generate a visible representation of said detected image.

9. The assembly of claim 8, wherein:

said hand held power tool is a saw, and

said working element is a saw blade.

10. The assembly of claim 8, wherein:

said hand held power tool is a router, and

said working element is a router bit.

11. The assembly of claim 8, wherein:

said hand held power tool is a drill, and

said working element is a drill bit.

12. The assembly of claim 8, wherein:

said hand held power tool further includes a base configured to contact a workpiece during use thereof, and

said base has an opening defined therein though which said working element extends.

13. The assembly of claim 12, wherein:

said base includes a leading edge and a trailing edge,

said opening is interposed between said leading edge and said trailing edge, and

said imaging device is attached to said base at a location that is interposed between said leading edge and said opening.

14. The assembly of claim 8, wherein said imaging device includes a video camera attached to said base.

15. The assembly of claim 14, wherein said video camera includes a CCD (charge coupled device) camera.

16. The assembly of claim 8, wherein said display device includes an LCD (liquid crystal display) screen.

17. The assembly of claim 8, wherein:

said display device includes a display screen,

said display screen includes a leading edge and a trailing edge, and

said leading edge is positioned vertically above said trailing edge, whereby said display screen assumes a tilted orientation facing toward a rear of said hand held power tool.

18. The assembly of claim 8, wherein:

said display device includes a display screen, and

said display device is configured to generate said visible representation of said detected image on said display screen.

19. The assembly of claim 8, wherein:

said hand held power tool further includes a base configured to contact a workpiece during use of said power tool, and

said imaging device is secured to said base.

20. The assembly of claim 8, wherein said display device is secured to said housing.
