Abstract
Abstract A display system which includes a plurality of separately activated light sources, a plurality of light guides coacting with each light source such that one end of each light guide is juxtaposed with a light source and the opposite end of each light guide is positioned in a display face such that the opposite ends of the guides are lighted according to a predetermined program when the light sources are activated. The light sources are programmed and the light guides are arranged in the display face to simulate light movement over the display face when the display system is operated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
A display system which comprises a. A plurality of separately activatable light sources, b. Sequential activation means electrically connected with each of said light sources for sequentially activating said plurality of light sources, c. A plurality of fiber light guides coacting with each separate light source such that one end of each light guide is juxtapositioned to a light source wherein the opposite end of each fiber light guide is lighted when the light source with which the one end of said fiber light guide coacts is activated, wherein the end of each fiber light guide opposite from the light source is spaced from adjacent fiber light guide ends, wherein adjacent fiber light guides at said opposite ends coact with different light sources, and wherein said plurality of fiber light guides at said opposite ends are arranged in a series such that one guide from each source is placed in a side-by-side relationship and the series repeated by placing a second guide from each source in a similar side-by-side relationship. d. And display face means for positioning the opposite end of each fiber light guide in a spaced, predetermined programmed relationship.

A display system which comprises a. A plurality of separately activatable light sources, b. Sequential activation means electrically connected with each of said light sources for sequentially activating said plurality of light sources, c. A plurality of fiber light guides coacting with each separate light source such that one end of each light guide is juxtapositioned to a light source wherein the opposite end of each fiber light guide is lighted when the light source with which the one end of said fiber light guide coacts is activated, wherein the end of each fiber light guide opposite from the light source is spaced from adjacent fiber light guide ends, wherein adjacent fiber light guides at said opposite ends coact with different light sources, and wherein said plurality of fiber light guides at said opposite ends are arranged in a series such that one guide from each source is placed in a side-by-side relationship and the series repeated by placing a second guide from each source in a similar side-by-side relationship. d. And display face means for positioning the opposite end of each fiber light guide in a spaced, predetermined programmed relationship.
Claim 3
Dependent Claim
191 words
A display system which comprises a. A plurality of separately activatable light sources, b. Sequential activation means electrically connected with each of said light sources for sequentially activating said plurality of light sources, c. A plurality of fiber light guides coacting with each separate light source such that one end of each light guide is juxtapositioned to a light source wherein the opposite end of each fiber light guide is lighted when the light source with which the one end of said fiber light guide coacts is activated, wherein the end of each fiber light guide opposite from the light source is spaced from adjacent fiber light guide ends, wherein adjacent fiber light guides at said opposite ends coact with different light sources, and wherein said plurality of fiber light guides at said opposite ends are arranged in a series such that one guide from each source is placed in a side-by-side relationship and the series repeated by placing a second guide from each source in a similar side-by-side relationship. d. And display face means for positioning the opposite end of each fiber light guide in a spaced, predetermined programmed relationship.
Claim 4
Dependent Claim
191 words
A display system which comprises a. A plurality of separately activatable light sources, b. Sequential activation means electrically connected with each of said light sources for sequentially activating said plurality of light sources, c. A plurality of fiber light guides coacting with each separate light source such that one end of each light guide is juxtapositioned to a light source wherein the opposite end of each fiber light guide is lighted when the light source with which the one end of said fiber light guide coacts is activated, wherein the end of each fiber light guide opposite from the light source is spaced from adjacent fiber light guide ends, wherein adjacent fiber light guides at said opposite ends coact with different light sources, and wherein said plurality of fiber light guides at said opposite ends are arranged in a series such that one guide from each source is placed in a side-by-side relationship and the series repeated by placing a second guide from each source in a similar side-by-side relationship. d. And display face means for positioning the opposite end of each fiber light guide in a spaced, predetermined programmed relationship.
Claim 5
Dependent Claim
24 words
