Patent number: 8111285Abstract: A stereoscopic display apparatus and a display method are provided. The stereoscopic display apparatus includes a display panel, a dynamic-backlight module, a tracking panel, an optical lens array. The display has an updated region and a non-updated region during a frame period the display panel displays according a first synchro-signal. The dynamic-backlight module has a plurality of light-emitting regions and the light-emitting regions are turned-on according to a second synchro-signal. The first synchro-signal and the second synchro-signal are synchronal. During the frame period, parts of the light-emitting regions corresponding to the updated region are synchronally turned-on and parts of the light-emitting regions corresponding to the non-updated region are synchronally turned-off. A light provided by at least the part of the light-emitting regions turned-on passes through one silt set and the display panel such that one of the single-eye images is only displayed by the non-updated region.Type: GrantFiled: May 11, 2009Date of Patent: February 7, 2012Assignee: Industrial Technolgy Research InstituteInventors: Jian-Chiun Liou, Kuen Lee, Jui-Feng Huang

Publication number: 20120019633Abstract: Described herein are techniques which facilitate the automatic synchronization of audio and video signals between an entertainment device and a presentation device. A sensing device detects and records timing information from a video test pattern generated by an entertainment device and output by a presentation device. Using the timing information from the sensing device, the entertainment device synchronizes the audio and video signals it outputs to one or more presentation devices. The presentation device exhibits synchronized audio and video to a user.Type: ApplicationFiled: July 26, 2010Publication date: January 26, 2012Applicant: ECHOSTAR TECHNOLOGIES L.L.C.Inventor: Eric Holley

Publication number: 20110279658Abstract: A method for synchronizing a function on a remote device with a function on a primary device includes selectively broadcasting, from a radio frequency (RF) transmitter of the primary device, data broadcast on channels at different times relative to a fixed period strobe signal of the primary device. Only the channels that have a noise level below a specified threshold level selectively broadcast the data and each of the channels have an associated fixed time frame offset relative to the fixed period strobe signal. Each of the channels is broadcast after their associated fixed time frame offset expires. An RF receiver of the remote device receives the data on one of the channels. The data on each of the channels is received at different times, depending on its associated fixed time frame offset, which results in the data on each received channel having an associated received time reference relative to a strobe signal of the remote device.Type: ApplicationFiled: May 11, 2010Publication date: November 17, 2011Applicant: FREESCALE SEMICONDUCTOR, INCInventors: Noriaki Masuda, Koichi Matsuo, Yuko Nakai

Patent number: RE43362Abstract: A method displays an image only to an authorized user by generating a mask image from a data image. The data and mask image are then displayed periodically in an alternating manner on a display device by a select signal. The opening end shutting of an optical shutter device is synchronized to the displaying of the selected images so that only the data image is perceived by the authorized user viewing the display device through the optical shutter device, and a gray image is perceived by an unauthorized user viewing the data and mask images directly.Type: GrantFiled: January 15, 2009Date of Patent: May 8, 2012Assignee: Binary Services Limited Liability CompanyInventors: William S.
