By internally reflecting the image-carrying light flux at all the sides, i.e.Type: GrantFiled: August 29, 2005Date of Patent: August 17, 2010Assignee: Nikon CorporationInventor: Yoshikazu Hirayama

Publication number: 20100121443Abstract: The invention relates to a device (1) for the vision correction of an eye (6), comprising: a converter (3, 3A, 3B, 5A, 5B) which can generate an electrical and/or magnetic and/or electromagnetic signal in response to the mechanical energy generated by a movement of the eye; and a soft lens (2) intended to be aligned with the eye. The converter is positioned in relation to the lens such that the electrical and/or magnetic and/or electromagnetic signal generated during the movement of the eye causes the optical properties of the lens to change. The invention is characterised in that the lens (2) includes a polymer material (7) containing a material (4) having a refractive index that can vary under the action of the electrical and/or magnetic and/or electromagnetic signal generated during a movement of the eye.Type: ApplicationFiled: February 8, 2008Publication date: May 13, 2010Applicants: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE- CRNSInventors: Francois Michel, Jean-Marc Buisine

Patent number: 7701532Abstract: To provide a sight controllable display device that is capable of switching a regular display and a concealed display easily. A display panel and a modulator are disposed between two polarizing plates. The display panel performs a regular display drive. Meanwhile, the modulator drives to operate at a speed faster than twice the speed of the display panel and modulate the display image of the display panel. When displaying an image that is desired to be concealed, the period where the modulator is not in action is selected and viewed by a shutter. By stopping the action of the modulator, the regular display can be viewed as it is without the shutter.Type: GrantFiled: March 6, 2007Date of Patent: April 20, 2010Assignees: NEC Corporation, NEC LCD Technologies, Ltd.Inventors: Ken Sumiyoshi, Koji Mimura

Patent number: 7667783Abstract: Systems, methods, apparatus and devices for head mounted stereoscopic 3-D display devices using the tunable focus liquid crystal micro-lens array eye to produce eye accommodation information. A liquid crystal display panel displays stereoscopic images and uses tunable liquid crystal micro-lens array to change the diopter of the display pixels to provide eye accommodation information. The head mounted display device includes a planar display screen, planar tunable liquid crystal micro-lens array and planar black mask. The display device may optionally include a bias lens. In an embodiment, the display device also includes a backlight and a prism sheet for displaying the images on the display screen. The display screen, tunable liquid crystal micro-lens array, black mask and optional backlight and prism may be flat or curved.Type: GrantFiled: June 1, 2007Date of Patent: February 23, 2010Assignees: University of Central Florida Research Foundation, Inc., Toppoly Optoelectronics Corp.Inventors: Qi Hong, Ruibo Lu, Thomas Xinzhang Wu, Shin-Tson Wu

Publication number: 20090317773Abstract: A system and method for flight training and evaluation of pilots comprises electronically activated vision restriction glasses that detect the pilot's head position and automatically darken and restrict the pilot's ability to see through the front and side windscreens when the pilot-in-training attempts to see out the windscreen. Thus, the pilot-in-training sees only within the aircraft cockpit, forcing him or her to fly by instruments in the most restricted operational mode.Type: ApplicationFiled: June 24, 2008Publication date: December 24, 2009Applicant: United States of America as represented by the Administrator of the N.A.S.A.Inventors: John J.
