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.
Claim 2
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 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
The display device of claim 1 wherein a first light source illuminates the first fiber light guide in each series of fiber light guides.
Claim 6
Dependent Claim 21 words
The display system of claim 1 wherein said activation means includes program means for alternatively activating and deactivating each light source.
Claim 7
Dependent Claim 40 words
The display system of claim 1 wherein the number of light sources is represented by the letter Y and the number of light guides coacting with each separate light source in Yn wherein the letter n is a whole number.
Claim 8
Dependent Claim 14 words
The display system of claim 4 wherein Y equals five and n equals one.
Claim 9
Dependent Claim 21 words
The display system of claim 4 wherein said activation means includes dimmer means for controlling the intensity of said light sources.
Claim 10
Dependent Claim 56 words
The display system of claim 1 wherein said activation means includes program means for activating and deactivating each light source such that the opposite ends of said light guides positioned in each said side by side series relationship are progressively activated and deactivated from one end of said series to the other end of said series.
Claim 11
Dependent Claim 25 words
The display system of claim 7 wherein said activation means includes means for varying the rate at which said light sources are activated and deactivated.
Claim 12
Dependent Claim 35 words
The display system of claim 7, wherein said program means simultaneously maintains a plurality of light sources activated to light a plurality of adjacently positioned opposite ends of said light guides in each said series.
