Abstract: A system and method for printing, protecting and authenticating packaging, tangible entertainment media and other products, including a combination of encoded numbers, letters or images (collectively, “indicia”) that is embedded into or printed onto a substrate at a location that is in plain view when incorporated into a package or product; a clear or translucent coating applied in a decoding pattern over the encoded portion of the substrate in such manner that the encoded indicia are readily viewable by and intelligible to a viewer; and an authenticating combination of indicia that is hidden from plain view and becomes visible to an authorized viewer only through destruction of the package or through close inspection of the product. Alternatively, the system can comprise an authenticating combination that is accessible to an authorized purchaser from a separate source or object, and possibly from a remote location.

Abstract: An image decoder system includes a series of optically or digitally encoded images mounted on a series of flat surfaces. A decoding lens is positioned over the encoded images. The decoding produces simulated three-dimensional image, simulated motion images or other visible effects. The system includes a backing plate to which the images and one or more decoding lenses are hingedly attached, resulting in a variety of decoding methods. To improve image clarity, locking devices such as Velcro fasteners, snaps, locking tabs, etc. are used to hold the lens to the image surface. Special inks for the encoded images and selected material for lens manufacture are used to improve contact between the image and the lens. Alignment marks are encoded with the image and used to match to alignment marks on the lens to clarify the decoded image. Wide, narrow and special combination lenticular lenses are used for special decoding effects.

Abstract: A competitive sport, and a facility for playing the same, the facility having a raised planar playing field formed of a plurality of rectangular trampoline-like channels held together edgewise by supporting cables with all of the adjacent edges and cables being covered by padding. The rectangular planar field is preferably circumscribed by additional similar panels angled upwardly and outwardly from the edges of the planar field with goals being provided in each of the end angled panels. The playing field may be divided and marked in predetermined ways depending upon the rules of the game. In one form, the game may involve two teams; one provided for each half of the field, with each team taking turns for prescribed periods in attempting to project a ball into a goal at the angled panels projecting upwardly from the end of the opponents' side of the field, while the defendant's attempt to thwart the defensive team's attempts to make a goal.

Abstract: A stereoptic viewer comprised of a vertical panel supported by rearwardly extending temples for mounting on a person's ears, the panel defining an opening through which both eyes of the person may see. A first side of the opening provides an unobstructed view of the screen or image to be observed, while the thin (second) side of the opening is intercepted by a mirror held at a 45 degree angle to pick up the image appearing on a second 45 degree angle mirror, extending away from the first side of the opening. Thereby, the image observed is slightly displaced to provide the stereoptic effect. At least one mirror may be slightly adjustable.
