  • Publication number: 20120077152
    Abstract: One or more transparent or translucent sheets of cellophane are folded and cuts are made to create symmetric patterns and designs. The cellophane creates diffraction, refraction, interference, and reflection pattern of light that become strikingly visible when viewed under polarized light. The cellophane patterns and designs are placed on top of one another such that the holes in the overlapping sheets cause a variation in the path of light traveling through the layers of the cellophane, creating beautiful and varied optical patterns of light that change with the placement of the layers of cellophane and with variation of the angle of polarized light for a kaleidoscope effect. The cellophane is viewed against the backdrop of a blue sky to provide a source of polarized light.

  • Patent number: 8107076
    Abstract: A variety of toy polariscopes are simpler in design and less costly than precision instruments used in scientific research and stress analysis of materials and structures. The toy polariscopes are designed for a variety of objects that may exhibit photoelastic properties such as glass, plastic, Plexiglas, gel candle material and other gels, and even edible photoelastic objects. They are specially designed for objects of various sizes with a variety of purposes such as objects to enhance learning in a variety of conditions and experiences. Special objects are designed to go with the toy polariscopes such as edible and inedible photoelastic objects, photoelastic candle material, a variety of photoelastic/photoplastic stands capable of a variety of displays in interaction with other designed photoelastic objects capable of a variety of interaction and displays. Other optical phenomena may also be observed.

  • Patent number: 8057090
    Abstract: A device and related method for mixing a powdered component and a liquid component with minimal user interaction are described. A powdered component and a liquid component are separately fed into a mixing chamber. The powdered component may be released into the liquid component by removing a barrier. Alternatively, the two components are drawn into the mixing chamber from respective sources by a vacuum. The mixture is sonicated at precise vibrational frequencies to control the physical properties of the final blended content. A piston-like device is used to remove the blended content from the mixing chamber.

  • Patent number: 7849785
    Abstract: A disposable packaging form is provided for brewed, hot drinks. The invention allows a user to brew the hot drink, squeeze out the brewed contents, and stir the contents of the hot drink. Each action can be performed multiple times before disposal. The present invention frees the user of the inconvenience of having to collect, wash, or dispose of the stirrers, squeezers and bags of the hot drink individually. A beverage apparatus has a rigid rod, a first manipulator connected to the rigid rod near the top of the rigid rod, and a second manipulator connected to the rigid rod near a bottom end of the rigid rod, a porous enclosure material, and beverage brewing contents within the enclosure. The second manipulator is a bottom cup and may be made as one unit with the rigid rod, serve as a stand, or serve as a caddy for a tea bag.

  • Patent number: 7477389
    Abstract: A toy, art object, decoration, ornament, entertainment device, advertising device, paperweight, or other device is made of a soft deformable plastic material in shapes of prisms, lenses, wedges, cubes, pyramids, as well as other forms that display the changing stress patterns formed by deformations of the photoelastic material. Magnets embedded in the material apply forces that create new patterns. Polarizing films within, or covering the clear plastic enhance the viewing effects. External forces, such as manual manipulation, springs, strings, elastic bands, clamps and other devices are used to create interesting optical effects. The viewing effects increase the entertainment and aesthetic value of the devices.
