Instrument panels in motor vehicles typically use round or near-round dials and gauges. Rectangular display devices, however, are common and quite inexpensive but they are rarely used as a gauge or dial in a motor vehicle instrument panel mainly because of subjective styling preferences. An apparatus that can obtain graphical, image information from at least a portion of a rectangular display device and economically and reliably provide at least some of that graphic information in a larger, round or near-round dial or gauge, would be an improvement over the prior art.

Other objects, features and characteristics of the present invention, as well as the methods of operation and the functions of the related elements of the structure, the combination of parts and economics of manufacture will become more apparent upon consideration of the following detailed description and appended claims with reference to the accompanying drawings, all of which form a part of this specification. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
Rectangular flat panel display devices, whether they are made of LEDs, liquid crystal or other technologies are well known. Their rectangular shape, however, is not preferred in motor vehicle instrument panel applications nor are they preferred in some aircraft instrument panel.
In
The bundle 312 comprises numerous fiber optic cables 308, which are tapered along the length of each cable between each cable's first and second opposing ends 309, 311. The bundle 312 can be formed by inserting tapered fiber optic cables into a light weight, rigid or semi-rigid truncated cone or funnel 314 and using an appropriate adhesive on the exterior surface of the cables to hold them in place, in the funnel. The funnel having a narrow first end 316 and tapering outward to a wider second end 318. The rate of tapering of the funnel 314 corresponds to the rate of tapering on the fiber optic cables 308, such that the first ends 309 of the cable fit within the first end 316 of the funnel 314 and the second ends 311 of the fiber optic cables 308 fit within the second end 318 of the funnel 314.
When several tapered fiber optic cables are bundled together, they form what is essentially a truncated, cone-shaped assembly 312 of such fiber optic cables having opposing first and second ends, 316 and 318 respectively. The lower or first end 309 is comprised of the first or smaller-diameter end of numerous tapered fiber optic cables and is thus narrower in diameter than the top or upper end 311. The upper ends 311 of the fiber optic cables in the bundle 312, provide an enlarged copy of image information input to each fiber optic cable at the bottom or lower end 309. Both ends of the bundle 312 are preferably flat or planar.
By locating the lower or narrow end of a bundle of tapered fiberoptic cables against a region of a conventional flat panel display, such as the one identified in
Alternatively, the cross-section of the cone or funnel 314 is provided with a specific shape for the desired shape of the image to be displayed. For example, if a star-shaped image, or other polygonal shaped image is desired the cross-sectional shape of the funnel 314 will reflect the desired shape of the image. The shapes listed here are merely suggestions. One skilled in the art would be able to determine other image-shapes that could be desired and how to retain the second ends 311 of the bundle 312 in such a manner to create the desired shape.
Those of ordinary skill should recognize that the apparatus described herein could be used with any type of flat panel display device, examples of which include LED and liquid crystal displays.
Those of ordinary should also recognize that fiber optic cables near the center of the truncated cone shown in
The tapered fiber optic cable could be made of any suitable light-transmissive material including glass, quartz and plastic.
For claim construction purposes, the term “round” should be construed to include round as well as near-round or oval.
The foregoing preferred embodiments have been shown and described for the purposes of illustrating the structural and functional principles of the present invention, as well as illustrating the methods of employing the preferred embodiments and are subject to change without departing from such principles. Therefore, this invention includes all modifications encompassed within the scope of the following claims.
