US Classification:

35613907, 356 401, 356 301

Abstract:

A system for measuring movement of an object includes a source of light for emitting a beam; an object for receiving the beam from the source and reflecting the beam; and a reflective optic for receiving the beam reflected from the object and again reflecting the beam at a first angle. The system also includes a receiver for receiving the reflected beam from the reflective optic. When the object moves in distance, the reflective optic reflects the beam at a second angle. The reflective optic may be replaced by an equivalent refractive optic(s). The receiver measures movement of the object, based on a difference between the first angle and the second angle. The reflective optic may include a cylindrical reflective optic, or a spherical reflective optic. The refractive optic(s) may include a plano hemispheric refractive optic, or a meniscus refractive optic. The receiver may include a quad-cell imaging system, or a focal plane array (FPA).

Abstract:

An electrician's conduit layout tool to facilitate placing conduit holes in electrical boxes wherein a small rectangular tool is provided having marking point for both sizes of strut, all parallel conduit marking locations in its peripheral edge and center marking locations for all conduit sizes on a one piece durable Tool. A three step method is used to layout any combination of conduits with no calculations. Is also used in strut rack layout parallel conduit marking locations in its peripheral edge. A panel schedule is also etched into the conduit layout tool for a wire-pulling guide. Lines are drawn through the center of the circumferential trace to facilitate the positioning of a conventional knockout.
