The present application is a continuation-in-part of U.S. patent application Ser. No. 10/836,132 filed Apr. 29, 2004 (Attorney Docket No. DEL 03-8-2), which in-turn claims priority under 35 USC §119(e) to provisional U.S. Application No. 60/466,199 filed Apr. 29, 2003 (Attorney Docket No. DEL 03-8-1). In addition, the present application claims priority entitled under 35 U.S.C. §119(e) to provisional U.S. Application No. 60/533,192 filed Dec. 30, 2003 (Attorney Docket No. DEL 03-47-1). Said U.S. patent application Ser. No. 10/836,132 and U.S. Provisional Patent Applications Nos. 60/466,199 and 60/533,192 are herein incorporated by reference in their entirety.
Referring specifically to FIG. 3, a laser beam 122 is shown contacting a body part 124 encroaching into a red zone 104 in accordance with a first aspect of the present invention. The laser beam 122 may serve as a visual cue to the operator that encroachment into the red zone 104 has occurred. It should be noted that the area enclosed by the laser beam 122 may correspond with the red zone 104, the yellow zone 106 (See FIGS. 1 and 2), or any number of predefined zones or points. It should also be noted that an operator of a power tool utilizing a video proximity device may define the area of a zone dynamically, and the laser beam 122 may be used to indicate the boundaries of such a zone. It should her be noted that a number of laser beam generating devices may be used to indicate a number of different zones, as contemplated by one of skill in the art.
16. The method of claim 1, wherein the detecting system recognizes the difference between the shapes of human body parts and a workpiece.
