摘要:
An apparatus for providing a dimensional display such as a 3D effect without special-purpose glasses. The apparatus includes a foreground display assembly including a first planar display element with a front surface and an opposite back surface. Additionally, the apparatus includes a background display assembly including: (a) a second planar display element spaced apart from and parallel to the first planar display element; and (b) a light source backlighting a back surface of the second planar display element. The first and second display elements are emissive display units and concurrently display frames of a foreground image stream and corresponding frames of a background image stream. The first display element may be a transparent LCD panel, and the output light from the front surface of the second display element provides backlighting for the first display element such that foreground images are backlit by output light of the second display element.

A three-dimensional (3D) display device combining two-dimensional (2D) images from two image sources to create a 3D image. The 3D display device utilizes a beam combining film that includes a prismatic front surface and a planar back surface. The film transmits light striking its back surface at particular incidence angles. A first 2D image source provides a foreground image and a second 2D image source to provide a background image. First and second liquid crystal displays may be arranged with display surfaces proximate to top and bottom edges of the beam combining film and at angular offsets to emit light corresponding with a 2D image stream onto the back surface of the beam combining film at one of the film's incidence angles. The 2D image streams striking the back surface of the film are combined by the film and transmitted from the front surface as a single autostereoscopic video image.

A three-dimensional (3D) display device creating 3D illusions or effects within a contained space or volume. The device includes a front sidewall providing a viewing window to an interior of the display device. The device includes a transparent rear projection screen with a front surface facing the viewing window that is spaced apart a distance from the front sidewall. A media source projects a two dimensional (2D) image onto a back surface of the projection screen in a direction that is oblique to the front sidewall. The projection screen is positioned such that the front surface is angled away from the front sidewall, whereby the front surface is oblique to the viewing window. A leading edge of the projection screen is proximate to the front sidewall and a trailing edge of the projection screen is distal to the front sidewall with the front surface angled away from the front sidewall.

A mobile electronic device configured to recharge when oscillated. The electronic device includes a housing with a battery compartment and a battery assembly positioned within the battery compartment. The battery assembly includes a rechargeable storage battery connected to device's battery contacts. The battery assembly includes a charging assembly connected to the rechargeable storage battery, and the charging assembly provides a kinetic energy-based generator operating during the oscillating motion of the electronic device to output electrical current to the rechargeable storage battery. The generator includes: (a) a barrel; (b) a permanent magnet positioned in an elongated chamber of the barrel and sliding within the chamber during movement of the device; and (c) a coil of conductive wire wrapped around an outer surface of the barrel. The chamber, generator magnet, and barrel outer surface receiving the coil all may be non-circular in cross sectional shape or non-cylindrical to improve kinetic energy harvesting.

A camera-projector assembly for viewing captured images in a near-view mode and in a distal-view projection mode. The assembly includes a camera housing and an image capture assembly within the housing collecting image data. The camera-projector assembly includes a projection assembly mounted on the camera housing that includes a projection lens and a projection light source. A transmissive display such as an LCD is provided external to the camera housing and adapted to be positionable in a first position proximate to the camera housing and in a second position between the projection lens and light source. The transmissive display is positionable against an external surface of the camera housing when it is in the first position and at least partially spaced apart from the external surface in the second position. The transmissive display maybe rotated or slid from the first to the second position on the camera housing.
摘要:
A projector for projecting diffracted light in a selectable pattern and/or animation on a display surface. The apparatus includes a light source providing one or more beams of coherent light from one or more lasers. The apparatus includes a diffraction assembly in the path of the light source to generate diffracted light by diffracting the laser light with one, two, or more diffraction grating patterns and, optionally, with a diffraction glass or other material. An active mask is provided with a raster that receives the diffracted light and that includes a plurality of optical shutter elements that are selectively operable to project a portion of the diffracted light from the active mask toward the display surface. In one example, the active mask includes a liquid crystal display panel to provide a grid of addressable programmable pixels that are turned on and off to project portions of the diffracted light.

A floor system for simulating a natural environment, such as snow, is disclosed. The system includes a confinement member that holds an aggregate. The confinement member may be positioned between a pair of disturbing agent layers comprising meshes that contact the confinement member at a plurality of discrete points. Force applied to the floor system by a user walking across the system results in force being communicated to the confinement member through the disturbing agent layers through the plurality of discrete contact points. The force applied at each of the discrete contact points causes portions of the aggregate proximate to the contact points to shift, resulting in vibrations and sounds that simulate the sound and feel of walking on snow. Additional layers for support, durability, and comfort may also be included in the floor system.

An apparatus is provided for generating or creating an autostereoscopic or three-dimensional (3D) display. The apparatus has a foreground display assembly including a display element such as a transparent projection screen film and a projector projecting a first set of two-dimensional (2D) content onto a rear surface viewable by a viewer via a front surface. The apparatus includes a background display assembly including a display element displaying a second set of 2D content. The apparatus includes an intermediate display assembly including a display element, such as an optical shutter window, positioned between the foreground display element and the background display element. This assembly includes a projector projecting a third set of 2D content on the front or rear surface of the optical shutter window. The first, second, and third sets of 2D content are concurrently visible and the use of three spaced apart display planes creates a 3D illusion.

A fog effects system includes a control system, a fog fluid reservoir, an elongated insulator, an elongated electric heating element, an air supply subsystem, a fog fluid supply subsystem, and a handheld body. The control system can include a battery-operated power supply and a user-operable control. The heating element extends along the insulator. The control system electrically energizes the heating element during system operation. The air supply subsystem directs a flow of air along the heating element during system operation. The fog fluid supply supplies fog fluid to the flow of air. The heating element vaporizes the fog fluid, which is emitted from an end of the system.
