This class is the residual locus of means and processes forcasting visible radiant energy in at least one direction to renderobjects in that direction visible.
BASIC SUBJECT MATTER OF THE CLASS
The basic subject matter of the class is comprised of:
A. The combination of a source of visible radiant energyand means to modify the distribution or composition of the radiantenergy emanating from the source.
B. Methods utilizing the combination of A, above, to castlight in at least one direction to render objects in that directionvisible.
SCOPE OF THE CLASS
In addition to the basic subject matter of the class, this classalso provides for:
A. Subcombinations of the basic subject matter of the classnot provided for elsewhere comprising:
1. means to modify the distribution of composition of lightfrom sources other than the heavenly bodies;
2. means to support a source of visible radiant energy;
3. means to support the modifying means of item 1, above,and
4. combinations of items 1, 2, and/or 3, above.
B. Combinations of the basic subject matter of the class andsubject matter classified elsewhere insofar as the combination isnot provided for elsewhere.
