| 20100202047 | STEREO DISPLAY SYSTEM WITH SCANNING OF LIGHT VALVES - A display method and system are described for displaying a stereo image comprising a first image and a second image. A light valve array comprising an array of light valve elements is driven according to an image and a light source is provided for generating a shaped light beam which can illuminate a portion of the light valve array. A scanning device is provided which is arranged to scan the shaped light beam across the light valve array. Light valve elements of the same light valve array are caused to sequentially adopt a state representative of the first image of the stereoscopic image and a state representative of the second image, and to cause the light valve elements to adopt a new state representative of one of the first and second images in advance of the scanning by the shaped light beam and to change to a new state representative of the other of the first and second images during a period between successive scans of the shaped light beam. | 08-12-2010 |
| 20100123880 | COLLIMATED VISUAL DISPLAY WITH ELLIPTICAL FRONT PROJECTION SCREEN - A front-projection display system having a screen with improved brightness and/or resolution of an image displayed on outer portions thereof. The screen has a display surface that is generally a convex shape having a curvature of the display surface in the vertical direction of an image projected thereon that is less than a curvature of the display surface in the horizontal direction. | 05-20-2010 |
| 20100099303 | Cable Connector - The disclosure herein describes embodiments of a cable connector that can be easily attached at a variety of points along the length of a cable as desired by a user for a particular application. The cable connector can easily be secured to the cable by snapping or otherwise securing the base and cover of the connector around the cable. The cable connector can include a device interface for coupling an electronic device to the cable connector. The cable connector can supply a power and control signal to the coupled device via terminals adapted to pierce the insulation on the cable and contact the conductors inside. The terminals of the cable connector can sever at least one of the conductors of the cable, disrupting the flow of current through the conductor. The device interface can bridge the severed ends of the conductor to enable unabated current flow when a device is not coupled thereto or redirect the current through an electronic device coupled to the interface. The cable connector enables easily connecting an electronic device in series between the severed ends of a conductor and providing current flow between the ends when the device is disconnect. | 04-22-2010 |
| 20090174867 | SYSTEM AND METHOD FOR REDUCING IMAGE ARTIFACTS IN A PROJECTION DEVICE USING A SCROLLING REFRACTIVE ELEMENT - A system and method for reducing speckle and smearing phenomena caused by a coherent light source. The light beam from the coherent light source is preferably refracted by a rotating refractive element. The refracted beam is focused and projected through a light valve by a plurality of optical components. The rotation of the refractive element causes the beam to scroll across the surface of a light receiving element, which reduces the smearing effect. The rotation of the refractive element also causes the propagation path of the beam to vary, causing rays of the light beam to undergo relative phase shift, varying the interference pattern on the light receiving element, resulting in a reduction in the appearance of the speckle phenomenon. | 07-09-2009 |
| 20090161196 | SYSTEM AND METHOD FOR SPECKLE REDUCTION FROM A COHERENT LIGHT SOURCE IN A PROJECTION DEVICE - Embodiments of the present invention are directed to a system and method for reducing speckle phenomenon caused by a coherent light source. Particular embodiments of the present invention are directed to a system and method for temporally varying the interference pattern generated by a coherent light source to homogenize the speckle pattern so that the speckle phenomenon is less observable. In accordance with an exemplary embodiment, an oscillating refractive element may be disposed within an optical system to create a temporally variable phase shift in the lights rays emanating from a coherent light source to eliminate static interference patterns on a light receiving element, reducing the speckle phenomenon. | 06-25-2009 |
| 20090147004 | Method And System For Combining Images Generated By Separate Sources - A system and method for combining images generated by separate sources. The system comprises a plurality of video image data sources that generate separate video images. The video images are captured and scaled by image processing hardware to fit within the viewports of a target window generated by a computing device. The parameters of the viewports are associated with the parameters of the target window such that changes to the target window result in corresponding changes to the viewports. The method comprises scaling the separate images to fit within the viewports using redundant data within each video image to interpolate pixel data at the boundary regions of adjacent images to eliminate artifacts at the boundary regions. | 06-11-2009 |
