Abstract: A gaming machine cabinet or housing is constructed from a plurality of connected components. In one embodiment, the cabinet is assembled from base, side, top, back and door components or sections. The housing may have a basis configuration constructed from a base, sides, top, back and a first door. The housing may have a plurality of modified configurations constructed from various of the basic configuration components, such as the base, sides and back, and an extension and modified door. In accordance with the invention, the gaming machine housing may be manufactured in one location and then conveniently shipped in unassembled form to another location for assembly and use. The gaming machine housing may also be constructed in a variety of configurations utilizing a small number of components.

Abstract: A generic, self-contained gaming device is transportable to various jurisdictions for use. The gaming device when associated with a terminal or gaming machine is configured and authenticated for use in the installed location to present one or more wagering games. The gaming device verifies associated components of the terminal or machine, and contacts a local authority, such as gaming regulator or licensed entity. The local authority provides authorization to operate. The gaming device is then activated to operate in a mode complying with local rules and regulations. In one embodiment, the gaming machine may generate location information and transmit that information to the authority. Authorization to operate may comprise an activation code causing the gaming device to operate in a particular mode, or executable code causing the gaming device to operate as required by governing rules and regulations where the gaming device is located.

Abstract: Input devices, such as push-buttons, are configured to display different colors, such as by emitting light in different colors. The displayed colors of the input devices are controlled so that a user may differentiate them and their associated functions. In one use, a gaming machine includes a plurality of color-codeable player input buttons. Buttons of a gaming machine which are used in active play of a game are configured to display a first color, such as by emitting green light, while inactive buttons are configured to display a second color, such as by emitting red light. When the input device is a push-type button, the displayed color may depend upon a color of a push-button cover, a plate associated with the cover, and/or the color of light emitted by a lamp of the button.

Abstract: A input device includes a user-engageable member associated with a signal generator. At least two elements of information are associated with the input device, each of which may be selectively rendered visible or readable to the user of the device based upon a color of light used to illuminate the information. In one form, the input device is a push-button of a gaming machine. Information associated with a button cover is illuminated with one or more LEDs. Combinations of colors of the information and emitted light are chosen so that elements of the information can be selectively rendered visible, permitting the configuration of the button to be changed, such as based upon a particular game to be presented.

Abstract: A gaming machine has a housing and a top panel which extends over an open top of the housing. A display is mounted to the top panel and a gaming controller is located within the housing beneath the display. Cooling air is drawn through one or more intakes in a front of the housing and expelled through one or more exhausts in a rear portion of the top panel at a location above the air intakes. The cooling air passes through a space between the gaming controller and the display, cooling those components.

Abstract: A pile weatherstrip is formed from a multiple-filament yarn that is knitted into a tape where the yarn lengths extend side-by-side in a direction normal to the length of the tape. Side-by-side yarns are held together by stitching to form a coherent tape which is then fed to a connection zone where the tape is formed into a V and the base of the V is welded into a channel on a carrier. After welding, the top ends of the V-shaped tape are cut off to form a pile.
