Abstract

A fastener driving tool is provided including a housing, a cylinder enclosed by the housing and at least one sensor associated with the cylinder. A piston is configured to reciprocate within the cylinder and has a driver blade depending therefrom. At least one signal generator is associated with the piston, where movement of the piston relative to the at least one sensor generates a signal.

Claims (30)

1 . A fastener driving tool comprising:

a housing;

a cylinder enclosed by said housing;

at least one sensor associated with said cylinder;

a piston configured to reciprocate within said cylinder and having a driver blade depending therefrom; and

at least one signal generator associated with said piston, wherein movement of said piston relative to said at least one sensor generates a signal.

2 . The tool of claim 1 , wherein said at least one signal generator includes a magnet and said at least one sensor includes an inductor.

3 . The tool of claim 2 , wherein said inductor includes at least one wire coil.

4 . The tool of claim 1 , wherein said at least one signal generator includes a plurality of magnets and said at least one sensor includes a plurality of inductors.

5 . The tool of claim 4 , wherein each of said plurality of inductors includes at least one wire coil.

6 . The tool of claim 1 , wherein said at least one sensor includes a wire coil.

7 . The tool of claim 1 , wherein said at least one sensor includes a plurality of wire coils.

8 . The tool of claim 1 , wherein said cylinder includes an outer peripheral surface and said at least one sensor is on said outer peripheral surface.

9 . The tool of claim 1 , wherein said at least one signal generator includes at least one annular magnet attached to said piston.

10 . The tool of claim 1 , further comprising a plurality of magnets attached to said piston.

11 . The tool of claim 10 , wherein said plurality of magnets includes cylindrical magnets spaced apart on said piston.

12 . The tool of claim 1 , further comprising at least one power storage device in communication with said at least one sensor for storing the electricity.

13 . The tool of claim 12 , wherein said at least one power storage device includes at least one battery.

14 . A fastener-driving tool comprising:

a housing;

a cylinder enclosed by said housing;

a plurality of sensors associated with said cylinder;

a piston configured to reciprocate within said cylinder and having a driver blade depending therefrom;

at least one signal generator associated with said piston, wherein movement of said piston relative to each of said plurality of sensors generates electricity; and

a storage device configured to receive and store the electricity.

15 . The tool of claim 14 , wherein said plurality of sensors each include at least one wire coil.

16 . The tool of claim 14 , wherein said plurality of sensors each includes a plurality of wire coils.

17 . The tool of claim 14 , further comprising a plurality of magnets attached to said piston.

18 . The tool of claim 17 , wherein said plurality of magnets includes cylindrical magnets spaced apart on said piston.

19 . The tool of claim 14 , wherein said at least one power storage device includes at least one battery.
