  • Patent number: 8116466
    Abstract: An apparatus and a method for testing a sound card are applicable for detecting whether a sound leakage problem occurs to a sounding interface of the sound card. The testing apparatus includes a switching circuit and a switching unit. The switching circuit is electrically connected to the sounding interface and a sound-receiving interface of the sound card respectively, and has a plurality of transfer paths. The switching circuit is used to receive a first and a second sound channel, and to connect the first and the second sound channel to corresponding transfer paths, so as to transmit the audio signal back to the sound-receiving interface. The switching unit is electrically connected to the sounding interface and the switching circuit, for receiving the first and the second sound channel. The switching unit alters the transfer paths in the switching circuit according to a first and/or a second switching audio signal.

  • Patent number: 8117432
    Abstract: A method for controlling a boot sequence of a server includes the following steps. A boot image is created, and a first proxy server program is placed into the boot image. The first proxy server program communicates with a management server. The boot image is restored on a rewritable removable storage device, so as to enable the rewritable removable storage device to boot a managed target server. A second proxy server program is installed and executed in the management server. A basic input/output system (BIOS) of the target server is set to enable the rewritable removable storage device to act as a first boot device. Boot files in the rewritable removable storage device are modified through the first proxy server program or the second proxy server program according to a boot instruction received from the management server, thereby controlling a boot sequence of the target server.

  • Patent number: 8059098
    Abstract: An electronic device with automatic switching input interfaces and a switching method thereof. The electronic device supports an Advanced Configuration Power Interface (ACPI), and includes a display unit, a storage unit, a memory unit, and an embedded controller. The display unit can be changed to a first position or a second position, and sends a signal to an embedded control unit when the display unit is at different positions. A management program running in the electronic device queries the ACPI and the embedded control unit to check the position and state of the display unit, so as to automatically load and run a corresponding program of a virtual input interface or a physical input interface into the memory unit, and remove the other program from the memory unit at the same time.

  • Patent number: 8059426
    Abstract: An electrostatic discharge guide using metal sputtering process and modifying plastic case is applied to an electronic device. The plastic case and a metal case are laminated. The plastic case is defined with a tip portion spaced from the metal case on side wall thereof. A conductive layer formed on the surface of the plastic case opposite to the metal case extends to the tip of the tip portion, and is electrically connected to a ground of the electronic device. Therefore, when electrostatic charges accumulated on the metal case exceed a specific value, the static electricity is discharged to the ground of the electronic device based on the point discharge principle, instead of causing an electric shock to a user.

  • Patent number: 6813642
    Abstract: A communication process by connecting a server end in series with a system under verification (SUV) in a network. The process initializes a communication port connected to server end and SUV and associated parameters through a computer in server end and SUV. Then creates a required thread and an associated interrupt program in server end and SUV respectively. When data has been received, the received data package is stored in an embedded buffer in server end or SUV until a complete data package is stored in the buffer. Next, data is transmitted through a predetermined data transmission module. By continuing this process, it is possible to transmit data by connecting server end in series with SUV through the connected communication port rather than network adapter. It is simple in operation and cost effective.

  • Patent number: 6442556
    Abstract: This specification discloses a decompression software package that can store files in an assigned storage device, which is mainly used to restore the previously partitioned/compressed files such as drivers, application programs or utilities downloaded from the network to a user assigned path or storage device. By directly running a decompression program, such as a quick release sector transfer (QRST) utilities, the user can select for the file to be restored a path of the storage device, such as a 1.44 MB floppy disk drive, an LS-120 or zip drive, or a hard drive. While restoring/decompressing the file, the software data such as the name of the software, version, etc, can be recorded to the aforementioned path, and a directory name can be built automatically at the same.

  • Patent number: 6405325
    Abstract: The present invention provides a method and tool for restoring a crashed operation system of a computer, for example, by operating under DOS environment to restore a crashed Windows system without requiring a long time setup and reinstallation. According to the present invention, a matching table for short file names to long file names is established for all files (containing directory names) on a disk. Then the long file names can be retrieved from short file names in accordance with the matching table. Since the long file names are stored in Unicode, they are workable for operation systems of any language.

  • Patent number: 6374265
    Abstract: This invention discloses a method for backup and recovery of the long filename in the computer system (e.g., DOS) that not support the long filename. The technique of the backup operation of this invention is to read the file directory table (FDT) from the logic partition of the hard disk by calling the basic input output system (BIOS) function; then transfer the long filename and short filename items into long filename format and saving to a backup file. Alternatively, recovering the backup is to search the short filename of each directory and sub directory and obtaining the data in the back up file; then write the matched long filename back to the original FDT.
