A user is able to save his operating system settings to a web server. The user may then download these known, clean operating system over the Internet to the same computer in the future or to a different computer. Or, a user is able to save a known, good restore point to a secure site on the web. If the user suspects that his computer has been compromised by malware, the user downloads this original restore point from over the Internet. The computer is then restored to a known, good state prior to the malware infection. In addition, an entire operating system is present on a USB drive and the user runs his computer from the USB drive. The USB drive is inserted into a publicly-accessible computer. Drivers and network settings from the computer are installed on the USB drive and the operating system on the USB drive then reboots and executes on the computer.

One embodiment relates to a method of providing a computer security service via instant messaging. An instant message is received from an originating user account. The instant message is parsed to identify files and universal resource locators (URLs) in the instant message. If any files are identified, then said identified file(s) are scanned for malicious code to generate scan results. If any URLs are identified, then said identified URL(s) are checked against a ratings database to generate rating results. A responsive instant message to the originating user account is generated, wherein the responsive instant message includes said scan and rating results. Other embodiments, aspects and features are also disclosed.

A display device including a first voltage generator, a second voltage generator, a timing controller, a level shifter and a display panel is provided. The first voltage generator is configured to generate a gate high voltage. During a first period, the gate high voltage is a first voltage. After the first period, the gate high voltage is a second voltage. The first voltage is higher than the second voltage. The second voltage generator is configured to generate a gate low voltage. According to the gate high voltage and the gate low voltage, the level shifter shifts the voltage levels of the start signal, the clock signal and the inverse signal produced by the timing controller for driving a plurality of shift registers disposed on a substrate of the display panel. The shift registers is configured to output scanning signals in sequence.

A method is used for adjusting a tilt of an optical pickup head. The method includes: identifying initial coordinates of the first static spot, the second static spot, and the dynamic spot in an image generated from three reflected light beams from the optical pickup head; turning one of the adjustable screws a predetermined calibrated rotation angle; recording current coordinates of the first static spot, the second static spot, and the dynamic spot in another image generated from three reflected light beams from the optical pickup head; calculating a total needed rotation angle of the one adjustable screw according to the initial coordinates, the predetermined calibrated rotation angle, and the current coordinates; and turning the one adjustable screw a remaining rotation angle computed by subtracting the predetermined calibrated rotation angle from the total needed rotation angle. An adjusting system is also disclosed.

A method is used for detecting a tilt of an optical pickup head. The method includes the steps of: capturing a plurality of images; converting the images to bitmap images; superposing the bitmap images together to form an superimposed bitmap image; setting a two-dimensional coordinating system of the superimposed bitmap image; determining coordinates of a first static spot, a second static spot, and dynamic spot; calculating a first distance between the first static spot and the dynamic spot, and a second distance between the second static spot and the dynamic spot based on the coordinates to determine a maximum distance; and comparing the maximum distance with a first standard distance to attain a conclusion whether the tilt is in an acceptable range.
