Abstract: A mobile promotional vehicle includes a tractor cab having an elongated, substantially horizontally extending bed connected thereto. An information display superstructure extends upwardly from the bed and includes side walls which converge as they progress from the rear of the bed forwardly in the direction of the cab. These side walls are joined by a top wall, and by a vertically extending rear wall. This allows the outer surface of the side walls to be better illuminated and more visible. Multiple display panels are stored inside the side walls and can be quickly transferred to an exposed, display position in juxtaposition to the outer surface of the side walls.

Abstract: A mobile promotional vehicle includes a tractor cab having an elongated, substantially horizontally extending bed connected thereto. An information display superstructure extends upwardly from the bed and includes outwardly leaning side walls which diverge upwardly, and converge as they progress from the rear of the bed forwardly in the direction of the cab. These side walls are joined by a horizontal, trapezoidally-shaped top wall, and by vertically extending, trapezoidally-shaped forward and rear walls. This allows the outer surface of the side walls to be better illuminated and more visible. Multiple display panels are stored inside the side walls and can be quickly transferred to an exposed, display position in juxtaposition to the outer surface of the side walls.

Abstract: A method and apparatus for enhancing a holographic image in order to create an eerie spiritual visual image which can be used in conjunction with religious pictures in hologram form or an eerie visual image of decorative scenes for home or office furnishing purposes or Halloween or other scary situations. A holographic film incorporating an image therein is placed between two plates of optically transparent material such as glass. A direct source of illumination of the image through candlelight set at the focal point distance in front of the hologram film, within its focal plane and at a location no lower than the lowermost point of the holographic image creates the enhanced image and eerie effect in a dark room.

In one embodiment the assembly includes two linear reflected lighting fixtures mounted with their axes in fixed spaced parallel relation, each of the fixtures being independently rotatable through a complete 360.degree. range. In a second embodiment, a first linear reflected lighting fixture is mounted on a second linear reflected lighting fixture such that the first fixture is selectively rotatable about three mutual transverse axes and is selectively translatable along the length dimension of the second fixture.

Abstract: An internally-illuminated medical data card in a credit card format containing a summary of the medical history of the bearer germane to his existing medical condition. The card, which is of laminated construction, includes a plastic core panel having light-transmitting properties, one face of the panel having formed thereon a metallized layer functioning as a double-faced mirror. Mounted on the layer and on the other face of the panel, respectively, are front and rear film transparencies containing medical data in a directly legible scale, the combined data affording the required summary. The long edges and one end of the panel are in a concave formation to define reflective convex terminations whereby light entering the remaining flat end is transmitted through the panel and is reflected by the convex terminations and by the inner face of the mirror to provide multiple internal reflection, causing the light to illuminate the front transparency to enhance its readability.

Abstract: A hollowed frustum display device for photographic artwork, the hollowed frustum having an optionally closed end opposing an open end, and being defined by a light transmitting material, a circumference of the open end being greater that the circumference of the closable end. Photographic artwork is applied preferably to inner surfaces of the hollowed frustum, with the photographic artwork being embodied upon a light transmitting material.

Abstract: A lenticular device is disclosed having a lens array with one or more lenticular convex ridges joined by cusped or concave valleys forming lens elements on one of its surfaces. In addition, the lenticular array is uniformly separated from a message transmitting surface by an air space directly related to a field of view of no more than 30.degree. determined by the converging light rays at the focal point. The carrier sheet or message is a plurality of messages resolved from a series of linear segments in the form of binary lineations placed in focus relative to the lens array. By establishing a proportional relationship between lens aperture and focal length, the rate of message change is predetermined for any prescribed viewing situation. Surface interference caused by reflection, chromatic diffraction, and other light loss is controlled by the relationship of optical design, and optical quality, coupled with other structural elements.

Abstract: This invention relates to a contrast maintaining means for use in display devices. The invention uses a substrate of synthetic paper having a light reflectance to light transmittance ratio which is in the order of 1 to 1. A substantially opaque coating material having a light reflection index near zero is deposited in the desired pattern upon the substrate so as to provide an information carrying display. The coated areas of the display neither transmit nor reflect a significant amount of light. When light reaches the display from behind the light transmitted through the substrate is of substantially the same intensity as the light that would be reflected from the substrate if the same light had reached the display from the front. The light reaching a viewers' eyes from the uncoated areas of the substrate is constant for nearly all lighting angles while substantially no light reaches the viewers' eyes from the coated areas of the display.

Abstract: An overhead sign having polyhedral sections tapered vertically in opposite directions, the lower section comprising downwardly converging translucent panels having picture transparencies backlighted by concentrated light from overhead fluorescent room lights while upwardly converging decorative opaque panels overhang the upper edges of the translucent panels to minimize front lighting and perceptively brighten the pictures viewed by customers as well as minimizing shadows on the display counters below the sign.
