## Background
TECHNICAL FIELD
The invention generally pertains to computer external hard-drives, and more particularly to a decorative enclosure that encloses a hard-drive and that includes a pair of LEDs that only illuminate when the computer is accessing the hard-drive.
BACKGROUND ART
In most developed countries, computers have become one of the most ubiquitous parts of everyday life. Either for business or personal use, computers have become an indispensable tool that people relay on to communicate, acquire information and store information.
During the last few years, computers have become useful for an even greater number of applications, such as audio and video production. The reason for this is because of increases in computer performance as a result of higher processor speeds and the greater amount of memory available, both of which can be manufactured and sold at much lower prices than before.
One of the most significant increases in computer performance is the size, and therefore storage capacity of hard drives. A hard drive is an information/data storage and retrieval device and is available as an internal version, which resides within a computer, or an external version. The external version is connected to the computer by means of a USB or IEEE 1394 (Firewire) cable and can be connected to a power source via an IEEE 1394 connector, a USB connector, or by a separate power cable.
External hard drives are especially popular due to the fact that they can be quickly and easily disconnected from the computer and transported. Unfortunately, computer hardware designers have long appeared to be more interested in the functionally and performance of an external hard drive, as opposed to the hard driver's physical appearance. Although some designers, such as Porsche, have began creating enclosures for external hard drives, the designs do not deviate too far from the standard square/rectangular shaped box.
What is needed is a new type of external hard drive enclosure that can function as required for the hard drive, but also has an appearance that will belie its purpose. By providing a hard drive enclosure with the appearance of an item, such as an automobile, a person will be able to effectively utilize an external hard drive while at the same time expressing some individuality.

DISCLOSURE OF THE INVENTION
The external hard drive enclosure (EHDE) is designed to provide a practical and aesthetic enclosure for operating and storing an external computer hard drive. In its basic design, the EHDE is comprised of two major inventive elements: an electrical circuit and a decorative enclosure. The inventive elements operate in combination with an a-c to d-c converter that is enabled by a utility power source which delivers a d-c voltage ranging from 5.0 to 6.5 volts d-c. The d-c voltage is utilized to power a computer and a computer/hard drive interface card that produces a first output and a second output that connect to the inventive electrical circuit.
The electrical circuit is comprised of a forward light circuit, a rearward light circuit and an optional interior light circuit. The forward light circuit, which is also referred to as a head light circuit in the preferred embodiment, utilizes two LEDs (DS1, DS2) that illuminate when power is applied to the computer. In one case, the output from the computer may be sufficient to operate the forward light circuit. If the computer does not have sufficient power, the forward light circuit can be directly connected to the output from the a-c to d-c converter via the computer/hard drive interface card. The optional interior light circuit utilizes at least one LED (DS3) that is connected in parallel across the forward light circuit. Therefore, when power is applied as described above, the interior light circuit will also illuminate.
The rearward light circuit, which is also referred to as a tail light circuit in the preferred embodiment, is connected to the second output from the computer/hard drive interface card. The second output is connected to two LEDs (DS4, DS5) that are activated when power is present at the second output, which occurs only when the computer is accessing the hard drive. Therefore, the two LEDs (DS4,DS5) illuminate in synchrony with the operation of the computer.
The decorative enclosure of the EHDE can be constructed of various materials such as plastic, wood or metal, and in various configurations such as a vehicle, a ship, an animal, a toy or in a variety of geometric shapes. For whatever configuration is selected, the decorative structure includes:
(1) a lower panel having means for receiving and attaching the hard drive and the computer/hard drive interface card. In one attachment means the lower panel can include a cavity into which is inserted and attached by complimentary hook and loop fasteners the hard drive and the computer/hard drive interface card,
(2) a right side panel and a left side panel that extend upward from the lower panel,
(3) a front panel and a rear panel that extend upward from the lower panel, wherein the front panel has a right and a left bore into which is inserted and attached the LEDS (DS1) and (DS2), and wherein the rear panel also has a right and a left bore into which is inserted and attached the LEDs (DS4) and (DS5), and
(4) an upper panel that interfaces with the upper edge of the right and left side panels, and the front and rear panels.
In view of the above disclosure, the primary object of the invention is to provide a decorative structure that encloses an external computer hard-drive. The decorative structure incorporates a set of LEDs that illuminate when the hard drive is powered, and a set of LEDs that only illuminate when the computer is being accessed.
