Patent application number	Title	Published
20100194865	METHOD OF GENERATING AND DISPLAYING A 3D IMAGE AND APPARATUS FOR PERFORMING THE METHOD - To provide an image of a scene having three-dimensional characteristics, without the use of special glasses, a special camera employing an electrically controllable LCD lens which may be changed as to focal length by varying an applied voltage is used to record a plurality of images of the scene at each of a plurality of closely spaced focal lengths. All of the recorded images are simultaneously displayed on a device employing a stack of transparent LCD screens with one image being provided to each screen in the same order as the focal lengths used during the recording step.	08-05-2010
20090245074	PICK-UP HEAD ASSEMBLY FOR OPTICAL DISC EMPLOYING ELECTRICALLY TUNABLE LIQUID CRYSTAL LENS - An optical disc storage system employs a read/write pick-up head assembly in which the optical path between the disc and the read/write light source, usually a laser diode, includes both a conventional objective lens formed of glass or plastic, with a fixed focus, and a liquid crystal lens which is electrically tunable to vary its refractive index and focal distance. The optical signal reflected from the disc is passed through this hybrid pick-up head assembly and demodulated to detect errors in the focus of the pick-up head and the tracking, and to adjust the focus by modifying the electrical signals applied to the LCD lens, and move the pick-up head in the plane of the disc to address the appropriate track.	10-01-2009
