Abstract
Abstract A device for producing at least one beam of light having a desired configuration includes a source (12) of concentrated light. A fiber optic conductor (18) transmits the concentrated light to one or more locations remote from the source. Light beam forming means (22) receive the light from the fiber optic conductor (18) and form same into one or more beams of light having the desired configurations, such as a plane.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
110 words
An object orienting device for producing at least one beam of light having a desired configuration and forming a reference datum for the object at an orientation location, said device comprising: a source of light positioned at one location; means for concentrating the light from said source; elongated, solid light transmitting means for receiving and transmitting the concentrated light to the orientation location that is remote from said first location; and lens means positioned at the orientation location for receiving the light from said transmitting means, said lens means forming the light into a beam of the desired configuration and projecting same as a reference datum at the orientation location.
Claim 2
Dependent Claim
110 words
An object orienting device for producing at least one beam of light having a desired configuration and forming a reference datum for the object at an orientation location, said device comprising: a source of light positioned at one location; means for concentrating the light from said source; elongated, solid light transmitting means for receiving and transmitting the concentrated light to the orientation location that is remote from said first location; and lens means positioned at the orientation location for receiving the light from said transmitting means, said lens means forming the light into a beam of the desired configuration and projecting same as a reference datum at the orientation location.
