Abstract: A force sensing cushion includes a force senor matrix and a calculating unit. The force sensor matrix is configured to detect stress distribution applied by a user sitting on the force sensing cushion. The calculating unit is connected with the force sensor matrix, and the calculating unit is configured to calculate a stress center of the stress distribution for tracking the posture of the user sitting on the force sensing cushion.

Abstract: A near-eye display device includes a display panel and a plurality of light modulation units. The display panel includes a plurality of display pixel units configured to emit display light. The light modulation units are disposed on a light emitting surface of the display panel, and each of the light modulation units is disposed corresponding to one of the display pixel units. Each of the light modulation units is configured to direct the display light emitted from the corresponding display pixel unit to an eye of a user, and a width of the display light directed to the eye of the user is smaller than the pupil size of the eye. The user may still receive clear images when the near-eye display is out of focus because the display light directed to the eye has the width smaller than the pupil size.

Abstract: Methods, apparatus, and systems for writing a playable unfinalized disc. The method generally includes the steps of (a) recording data to the disc, (b) calculating a length of metadata based at least in part on a writing position on the disc, (c) determining a content of the metadata based at least in part on a data format and/or a disc format, and (d) recording the metadata to the disc at a position following and adjacent to the data. The apparatus generally includes (a) a disc loader configured to write data to the disc and to write metadata to the disc at a position following and adjacent to the data, and (b) a burning engine configured to send the data to the disc loader and to calculate a length of the metadata based at least in part on a writing position on the disc. The present invention advantageously allows users to view and/or share video content at any time without finalizing the disc (e.g., without recording on the lead-in area of the disc).

Abstract: A parallax barrier 3D display utilizes adjustable at least one parallax barrier for having an observer always retrieve stereo vision no matter whether horizontal or vertical movements towards the parallax barrier 3D display are made. The parallax barrier is adjustable in its width and a distance from the parallax barrier 3D display, or a parallax barrier having an appropriate width or distance may be chosen from each parallax barrier set. Therefore, the observer does not have to search for sweet spots nor keep on staying at the sweet spots for retrieving stereo vision.

Abstract: A method for determining a disc format is disclosed. Data from at least one address of the disc is retrieved, wherein the at least one address is selected from a plurality of predetermined addresses related to the disc format. The disc format is determined according to the retrieved data.

Abstract: A method for detecting a disc, the method includes the steps of: reading a file system of the disc; determining a type of the disc according to the file system; and abandoning a multi-session checking process upon the disc if the type of the disc is a one-session disc.

Abstract: The invention provides a method for reading disk management data of an optical disk. In one embodiment, the disk management data comprises data layout information of the optical disk, and a plurality of disk management data copies of the disk management data is stored on the optical disk. First, a first disk management data copy selected from the plurality of disk management data copies is read from the optical disk. An accuracy measure of the first disk management data copy is then calculated to determine whether the accuracy measure of the first disk management data copy is acceptable. When the accuracy measure of the first disk management data copy is acceptable, the optical disk is accessed according to the first disk management data copy.

Abstract: An optical disc player for playback of a multimedia file stored in an optical disc is disclosed. The optical disc player includes a front-end loader and a back-end playback engine. The front-end loader, including a first data buffer, reads data from the optical disc and stores the read data in the first data buffer when the amount of data stored in the first data buffer is less than a first threshold. The back-end playback engine receives the data from the first data buffer and plays a multimedia segment corresponding to the received data. The front-end loader increases the first threshold of the first data buffer before a time-consuming servo behavior occurs.

Abstract: A method of recording data on a storage medium is provided. A first recording indicator is written on the storage medium to indicate a first state of a data recording thereon.
