Abstract

Abstract A display device includes a plurality of optical fiber elements which are bunched together at one end adjacent a light source. The light emitting ends of the optical fiber elements pass through apertures in a moveable panel. The apertures may be arranged into a desired configuration and, in part, serve as locators for the light emitting ends of the optical elements. The moveable panel is moveable to a first position proximate the light emitting ends of the optical fiber elements, and where so positioned, the ends of the optical fiber elements are moved to substantially conform to the pattern of the apertures in the moveable panel to present an illuminated display substantially the same as the aperture pattern. The moveable panel is then moveable to a second position in which it is displaced from the light emitting ends of the optical fiber elements, and when so positioned the ends of the optical fibers move to form a second image distinct from the first. The moveable panel may be moved from the first to the second positions repeatedly to create a display in which the light emitting ends forming the first image are oriented by the movement of the panel into a second image.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 198 words
A fiber optic display device comprising: (a) a plurality of flexible elongated optical fiber elements each of said optical fiber elements having a light receiving end and a light emitting end; (b) a source of illumination constructed and arranged to illuminate said light receiving ends of said optical fiber elements; and (c) image forming means constructed and arranged to place said light emitting ends of said optical fiber elements into two or more image displays including: (i) a moveable panel member provided with a plurality of apertures therethrough, said aperatures being in a pattern substantially corresponding to a first image to be displayed said optical fibers freely passing through said aperatures; and (ii) displacement means constructed and arranged to move said panel member between a first position proximate the light emitting ends of said optical fiber elements whereby said light emitting ends of said optical fiber elements conform substantially to the pattern of said aperatures in said panel and a second position wherein said panel members is spaced from said light emitting ends in the direction of said light receiving ends whereby said light emitting ends of said flexible optical fiber elements, conform to a second image pattern.
Claim 2
Dependent Claim 198 words
A fiber optic display device comprising: (a) a plurality of flexible elongated optical fiber elements each of said optical fiber elements having a light receiving end and a light emitting end; (b) a source of illumination constructed and arranged to illuminate said light receiving ends of said optical fiber elements; and (c) image forming means constructed and arranged to place said light emitting ends of said optical fiber elements into two or more image displays including: (i) a moveable panel member provided with a plurality of apertures therethrough, said aperatures being in a pattern substantially corresponding to a first image to be displayed said optical fibers freely passing through said aperatures; and (ii) displacement means constructed and arranged to move said panel member between a first position proximate the light emitting ends of said optical fiber elements whereby said light emitting ends of said optical fiber elements conform substantially to the pattern of said aperatures in said panel and a second position wherein said panel members is spaced from said light emitting ends in the direction of said light receiving ends whereby said light emitting ends of said flexible optical fiber elements, conform to a second image pattern.
Claim 3
Dependent Claim 26 words
The fiber optic display device in accordance with claim 1 wherein said second image is formed by said light emitting ends in a randomly dispersed arrangement.
Claim 4
Dependent Claim 29 words
The fiber optic display device in accordance with claim 1 wherein each of said light emitting ends of said optical fibers passes through a separate aperture in said panel.
Claim 5
Dependent Claim 41 words
The fiber optic display device in accordance with claim 1 further including a stationary support member oonstructed and arranged to support said optical fiber elements positioned between said moveable panel member and said light receiving ends of said optical fiber elements.
Claim 6
Dependent Claim 33 words
The fiber optic display device in accordance with claim 4 wherein said stationary support member is provided with a plurality of apertures therethrough, said optical fiber elements being fixedly positioned within said apertures.
Claim 7
Dependent Claim 35 words
The fiber optic display device in accordance with claim 5 wherein said apertures in said stationary support member are oriented in a pattern differing from the pattern of said apertures in said moveable panel member.
