353062000 | STENCIL OR PERFORATED PLATE PROJECTOR (E.G., SKY OR CLOUD PROJECTOR) | 11 |
20090103056 | PROJECTOR WITH A LENS COVER - A projector includes a light source, a light modulator for modulating light emitted from the light source, a lens module projecting the modulated light to form an image on a surface, and a lens cover. The lens cover includes a base portion positioned to the lens module, and a pattern defined in the base portion. When the projector is in operation and the lens cover is mounted on the lens module, an image is projected on the surface corresponding to the pattern. | 04-23-2009 |
20090213340 | DEVICE FOR FORMING VISIBLE IMAGE IN AIR - The present invention relates to a device for forming a visible image which can draw a two-dimensional or a three-dimensional visible image without having a scanning locus of a laser beam recognized. | 08-27-2009 |
20090273762 | Simplified planetarium apparatus and simplified image projecting apparatus - Light emitted from a light source passes through a stellar base plate, a fixed aperture, and a wide-angled projection lens via a condenser lens and projects a starry sky on a screen. The stellar base plate is a light-shielding disk having a number of through holes which correspond to positions and brightness of actual stars, is supported by an inner ring of a ball bearing having the center at a position corresponding to the axis of rotation so as to be capable of rotating about the axis of rotation, and is driven by a motor via a belt. The centers of the projection lens, a window of the fixed aperture, the condenser lens, and the light source are all arranged on the optical axis, and the centers of the stellar base plate, the pulley and the ball bearing correspond to the axis of rotation. | 11-05-2009 |
20090296048 | Lighted Image Rendering Lamp - Disclosed herein is an illuminating apparatus for rendering lighted images of different shapes in different directions. The illuminating apparatus comprises a lamp fixture, a perforated dish affixed to the lamp pipe, a lamp shade affixed over the perforated dish, and a dome cover affixed on top of the lamp shade. The lamp fixture comprises a light bulb socket, a lamp pipe, and a lamp base. A light bulb is affixed to the light bulb socket and enclosed within the lamp shade. The dome cover comprises multiple inscriptions. The lamp shade comprises a layered mesh. The layered mesh may comprise wires crossing at right angles. On lighting the light bulb, the light passes through the perforations of the perforated dish, the inscriptions of the dome cover, and between the wires of the layered mesh, thereby rendering the lighted images of the different shapes in different directions. | 12-03-2009 |
20090303448 | STAR FIELD PROJECTION APPARATUS - A projection apparatus for generating a moving star field and a cloud-like effect comprises a means for generating a cloud-like effect using at least one non-coherent light source, a means for generating a moving star field using at least one coherent light source and a means for regulating and supplying electric power. The means for generating cloud-like effect using at least one non-coherent light source comprises at least one pair of condenser lenses and an interferential filter wheel rotated by a motor, disposed between at least one pair of condenser lenses. The means for generating the moving star field using a coherent light source comprises a grating wheel rotated by a motor and a diffractive optical element disposed between the at least one coherent light source and the grating wheel. | 12-10-2009 |
20090323031 | CANDLELIGHT IMAGE PROJECTING APPARATUS AND METHOD - A candlelight image projecting apparatus and method preferably includes structure and/or function whereby a panel has a shadow-producing image disposed thereon, and a base is coupled to the panel. Preferably, the base is configured to hold a candle spaced from the panel such that a top of the candle flame is always below a top of the shadow image to cause a top of the shadow image to always be projected above the top of the panel. The base may be configured to hold an outer surface of a candle from 1-3 inches from the panel and so that the top of the candle flame is below a top of the shadow-producing image to cause an enlarged shadow to be projected upward from the panel. | 12-31-2009 |
20110134397 | AVIAN DETERRENT FOR GLASS - An apparatus for preventing bird collisions with a window including a UV light source, a mask, and a first lens configured to direct UV light from the UV light source through the mask. The mask is at least partially transparent to UV light and includes a pattern that is at least partially opaque to UV light. The UV light passing through the mask contains the pattern. The pattern-containing UV light is projected onto a pane of glass to form a UV image visible to birds corresponding to the pattern on the pane. The image is configured to deter birds from flying into the pane of glass. | 06-09-2011 |
20110170072 | Dual in Focus Gobo - A gobo holder with two gobos that are rotatable one relative to the other. The gobos are located with their patterned surfaces facing one another and very close to one another so that both can be in focus at the same time. | 07-14-2011 |
20130070212 | Method and apparatus for making a high resolution light pattern generator on a transparent substrate - A light pattern generator that can be used to form a gobo for use in a projection optical system. A transparent plate is coated with a stack that is absorptive and reflective. The stack is formed to be ablatable in the form of a pattern. The stack can have multiple different layers with multiple different characteristics, all of which are ablated by the laser. | 03-21-2013 |
20140016103 | INTERACTIVE CONTROL SYSTEM, METHODS OF MAKING THE SAME, AND DEVICES INCORPORATING THE SAME - Numerous embodiments of interactive control systems, methods of making the same, and devices incorporating the same are disclosed. In one embodiment, a system includes a light-resistant material; light-transmissive holes penetrating in a light-transmissive pattern through the light resistant material; and a lens disposed adjacent to the light-transmissive pattern. | 01-16-2014 |
20150049312 | TOY IMAGE PROJECTOR - A toy image projector includes a housing including a peripheral wall, an accommodation chamber surrounded by the peripheral wall and a transparent view window at the peripheral wall, a rotating body accommodated in the accommodation chamber and including a peripheral wall, multiple sets of patterned holes formed in the peripheral wall and a space surrounded by the peripheral wall, a driving mechanism operable to rotate the rotating body relative to the housing, and a light-emitting device accommodated in the space within the rotating body and adapted to emit light through one set of patterned holes and the transparent view window to the outside. Thus, by means of rotating the rotating body, different image patterns can be projected to the outside of the toy image projector, increasing consumer interest in playing the toy image projector. | 02-19-2015 |
