  • Patent number: 11151911
    Abstract: A display of real world scenes comprising one or more optical mirror film surfaces having one or more selected deformations on said surfaces including a plurality of flat mirror facets, a plurality of folded mirror ridges, and a plurality of mirror vertices capable of capturing and transforming said scenes into other-worldly virtual images for recorded play back video image of said virtual images and other applications; including a method of imposing one or more selected ordered and disordered deformations on said mirror film surface irreversibly as a means of forming surfaces useful for the function of said virtual imaging display.

  • Patent number: 6627275
    Abstract: An airbag copmrising crystal gels is disclosed. The crystal gel comprises one or more block copolymers having at least one crystalline midblock and high levels of a plasticizer. The midblock segment has an amount of crystallinity sufficient to achieve improvements in one or more physical properties including improved crack propagation resistance, improved tear resistance, improved resistance to fatigue and resistance to catastrophic failure.

  • Patent number: 6033283
    Abstract: Dynamic, spinning, twisting string toys referred to as "humdingers" are disclosed. The toys include at least one highly elastic gel body having at least two holes extending through the body along a selected axis of rotation. The holes are treaded with a string(s) which are twisted and untwisted alternatively by the pulling and releasing action of the strings. The holes are provided with means to resist the shearing forces of the twisting strings. The dynamic effect of the extreme high centrifugal and shearing forces generated during play causes the gel bodies to change shape during spinning. Soft gels or low strength materials can also be substituted in place of the highly elastic gel body provide the body reinforced with shear resistant means to prevent cutting by the twisting and untwisting actions of the string(s).

  • Patent number: 5868597
    Abstract: A novel rotating aerodynamic toy made of a ultra-elastic gel airfoil which is suitable for launch in light or heavy wind conditions and capable of performing various aerodynamic effects including climb, stall, return, straight-line flight and other aerobatics. The ultra-elastic properties of the airfoil allow the airfoil to transform by at least 50% extension of its aerodynamic profile at launch and; while in flight; one or more preselected sized cavities and holes, slots and holes, cavities, slots and holes and cavities, slots, or holes provide handling, elastic control of airfoil profile stretching for flight, and flight stability.
