  • Publication number: 20130332698
    Abstract: A data preservation method applicable to an electronic device operating with an open operating system having a data storage region includes creating a disk partition; creating an authority to access the disk partition and get linked to a group ID (GID); mounting the disk partition in a directory having a user ID (UID) and the GID; and giving authority related to the linked GID to an application having the authority, so as to access data in the disk partition having the GID. The authority, coupled with the GID, allows a specific disk partition to store data generated as a result of execution of the application. Even if the application causes a UID change later for some reason, the application bestowed with the authority can still access data through the GID, thereby preserving data.

  • Patent number: 8261626
    Abstract: A ball screw comprises a shaft, a nut, two return elements, plural rolling elements and a sleeve. When being rotated, the shaft will drive the nut to move and circulate the rolling elements within a circulation path defined by a loaded path and the return passages of the return elements. The nut is provided with a circular groove in an outer circumferential surface thereof, and the sleeve is disposed in the circular groove. The sleeve is provided with plural push grooves in an inner circumferential surface thereof, and there is an angular difference between a rolling passage in the nut and the respective push grooves, and the push grooves cooperate with the rolling elements which pass through the rolling passage. By such arrangements, the push grooves of the sleeve will be pushed by the rolling elements to convert the linear motion into rotary motion, thus making the sleeve rotate.

  • Patent number: 8149205
    Abstract: A circuit for driving an LCD panel and a method thereof is provided. The circuit utilizes a timing controller to receive a plurality of low-voltage differential signals (LVDS) provided by an image inverter, wherein the LVDS have a horizontal synchronize signal. The timing controller, based on the horizontal synchronize signal, undergoes a modulation and transmits a plurality of lamp operation controlling signals to an inverter controlling IC, wherein the frequencies of the lamp operation controlling signals are different from one another, thereby changing the frequency of the lamp operation of the inverter controlling IC used in the LCD panel.
