  • Publication number: 20160063542
    Abstract: As provided herein, information associated with a first product may be provided to a device using an identifier that corresponds to the device and that is received from a different device. For example, a selection associated with the first product may be received (e.g., by a server) from the different device. A request for the identifier may be provided (e.g., by the server) to the different device. The identifier may be received (e.g., by the server) from the different device, and information associated with the first product may be provided (e.g., by the server) to the second device using the identifier.

  • Publication number: 20050190574
    Abstract: An illumination system employs a light distribution cylinder with an exterior surface in the form of a plurality of progressively smaller-diameter cylindrical steps. The outside surface of each cylindrical step is interrupted by V-shaped grooves perpendicular to the axis of the cylinder. Each surface of these V-shaped grooves acts to internally reflect divergent light from a light source positioned at the end of the tube. The light distribution cylinders may be solid or hollow and configured with bilateral symmetry to receive light from either end. The illumination system rearranges divergent directional light from a light source into non-directional light emitted in a cylindrical pattern useful for area illumination.

  • Patent number: 6483499
    Abstract: A sculpturing input device for computerized 3D sculpturing includes a base for connection to a computer loaded with a virtual engraving program, and a magnetic stylus for use with the base for controlling a virtual engraving tool to cut a virtual object of the program. An optical position measuring system is provided in the base for measuring the position and direction of the stylus relative to the base, and determining the position and direction of the tool relative to the object. A magnetic force feedback system is provided in the base for exerting a magnetic resistive force upon the stylus when the tool cuts into the object, thereby simulating a counteracting resistive force of the object being cut.
