## Background
This application is based upon and claims the benefit of priority from U.S. Provisional Application 60/982,223 filed on Oct. 24, 2007 in the United States Patent and Trademark Office, the disclosure of which is incorporated herein by reference in its entirety.


FIELD OF THE INVENTION
The present invention is directed to a video display, more specifically to a video display to be used to present information on welding techniques and equipment having attached thereto a replica of a welding helmet and a welding gun.
BACKGROUND OF THE INVENTION
Welding equipment and consumables are sold and rented in a variety of outlets, including well known big-box style home improvement stores, welding specialty shops and equipment rental stores. The level of knowledge available in these various types of retail establishments can vary highly from location to location. At a welding specialty store, salesmen are likely to be more knowledgeable about welding equipment and processes. These types of stores, however, are not as prevalent and not accessible to many consumers. At big-box style home improvement stores, now ubiquitous on the American landscape, salesmen are less likely to be knowledgeable out welding equipment and processes. Because of the several types of welding techniques, e.g., Metal Inert Gas (MIG), and Tungsten Inert Gas (TIG), and the different types of welding equipment, it is important that the consumer obtain proper guidance and instruction as to the appropriate type of welding equipment and consumables suitable for the consumer's needs and skill level.
In the past, consumers were required to rely on their own knowledge, the knowledge of the salesman, catalogs and/or sales collateral. The consumer's knowledge can be incorrect particularly for novice welders. Salesmen are often responsible for many types of products and do not always have detailed knowledge of the products they sell. Further, salesman can offer biased advice based on the potential commissions they might earn. Catalogs are quickly out of date and can present only a limited amount of information.
Accordingly, there is a need for an apparatus that will allow consumers to easily obtain accurate and comprehensive knowledge about welding equipment, techniques and processes.
The present invention provides such a solution.
SUMMARY OF THE INVENTION
As stated above, the present invention is directed to solve the above problems by providing an attractive, low-cost video display capable of presenting comprehensive information on welding equipment and processes to consumers.
The present invention solves this problem by providing a display system, the system comprising a housing; a display; a first control device; a controller configured to control the display based upon input from the first control device; and a viewer, the viewer having an opening, wherein the viewer is mounted on the housing with the display visible through the opening, and wherein the viewer is formed in the shape of a welding helmet
Various embodiments of the present invention will be discussed below.

A second opening 140a is provided in another portion of housing 130 to allow for the installation of a control panel 140. Housing 130 can also include mounting means 160 for mounting the viewer 110 to the housing. Mounting means 160 can be any means capable of securedly mounting viewer 110 to housing 130, e.g., adhesives, screws, bolts, hook-and-loop fasteners, nuts, etc.
Display 120 is a display capable of displaying still and moving images. Display 120 can be any number of types of well known displays, such as a liquid crystal display, a plasma display, or a cathode ray tube. Display 120 displays images to a user upon input from control panel 140 and/or control device 150.
Control panel 140 presents a variety of selection and/or control means 40b, e.g., buttons, dials, switches, knobs, keyboards, mice, touch screens, etc., to allow a user of display device 100 to select which programs to run or which images to display on display 120. When a user operates one or more of the selection and control means 40b on control panel 140, input is sent to controller.
Control device 150 allows a user to provide input to controller. Control device 150 can be any number of well known selection and/or control means. In this embodiment, control device 150 is configured to resemble a welding gun. However, control device 150 is not required to have such a configuration. In some embodiments, control device 150 could be entirely omitted from display device 100.
Speakers 170a and 170b may also be included on display device 100. In this embodiment, speakers 170a can be mounted in housing 130 and speakers 170b are mounted in viewer 110. Speakers 170a and 170b are provided to allow audio to be played to a user of display device 100.
