Abstract: Disclosed is a planar inverted-F antenna with an extended grounding plane. The planar inverted-F antenna has a grounding metal plate having a selected side edge on which the extended grounding plane is formed and has a predetermined height. At least one antenna signal radiating plate is connected to the grounding metal plate by a short-circuit piece and is substantially parallel to and spaced from the grounding metal plate by a distance. A feeding point extends from the antenna signal radiating plate in a direction toward the grounding metal plate and corresponds to the extended grounding plane with a predetermined gap therebetween. With the arrangement of the extended grounding plane, the impedance matching of the antenna is improved and the impedance bandwidth of the antenna is increased.

Abstract: A data display method for digital storage devices implemented on a computer executable platform. The invention reads data through a dynamic setting of a Basic Input/Output System and a card read controller, and selectively displays the data on a display device without entering the operating system. This greatly improves the convenience of using digital storage devices.

Abstract: A brightness correction method for a display panel, comprising showing a plurality of image areas in the display panel, wherein the image areas display different colors, each color has a plurality of luminance values according to a plurality of gray values, and wherein each gray value corresponds to a gamma voltage; detecting the luminance values; and adjusting the gamma voltages according to the detected luminance values.

Abstract: A universal electrical plug includes a first support, a second support, outer electrode slats, and inner electrode slats. An axis is defined from the second support to the first support. The outer and inner electrode slats are arranged on the second support, surround the axis, and extend to the first support in a direction parallel to the axis. The outer electrode slats are arranged on the second support and surround the inner electrode slats. Each outer electrode salt includes an outer deforming section bulged from the axis to fit insert holes of the electrical sockets with different sizes. Each inner electrode slate includes an inner deforming section depressed toward the axis to fit the electrode cores of the electrical sockets with different sizes. Through the outer and the inner electrode slats, the universal electrical plug is able to be adapted to the electrical sockets with different geometry specifications.

Abstract: A method for executing computer programs in accordance with a preset priority is provided. The method is applicable to a computer system connecting to a data storage, a plurality of device selection buttons, and a plurality of multimedia players. The data storage is installed with a plurality of device drivers, a plurality of device application programs, and a program execution priority table. The program execution priority table defines correspondence between the device selection buttons and the multimedia players, and the priority order of execution of the device drivers and the device application programs of the multimedia players. When the computer detects any device selection button is pressed, the computer executes the device drivers and the device application programs corresponding the multimedia player in the priority order defined by the program execution priority table.

Abstract: A preheating control system of an information processing device and a control method thereof are described. The system includes a temperature sensing module, a first controller, a heating module, and a second controller. After receiving a power ON signal, the first controller shifts to a primary control mode and determines whether temperature of the hard disk satisfies an operating temperature scope or not. When the temperature does not satisfy the operating temperature scope, the heating module is used to heat the hard disk. When the temperature satisfies the operating temperature scope, the first controller shifts to a secondary control mode and activates the second controller to execute a boot program of the information processing device, thereby improving system stability.

Abstract: A falling protective device for protecting a hard disk of a falling portable computer against damages includes a falling sensor arranged in the portable computer for generating and sending an interrupt signal to a keyboard controller in response to a detected falling state of the computer. An SMI signal line is extended between and connected to the keyboard controller and a system BIOS of the computer. On receipt of the interrupt signal generated by the falling sensor, the keyboard controller sends an SMI signal via the SMI signal line to the system BIOS, which in turn sends a park control signal to park the hard disk or a power-off control signal to terminate the supply of working power to the hard disk. The system BIOS sends a polling signal via a polling signal line to the keyboard controller, so as to poll about a state signal of a default status bit in a default signal port of the keyboard controller.

Abstract: An auto switch system and method thereof for IP phones and default audio devices. The system may automatically switch voice output of an information apparatus between the IP phone and the audio device according to IP phone usage. Thus, inconvenience caused by the IP phone being set as the default output is overcome. Furthermore, users need not change the settings when using IP phones.

Abstract: A drainage structure is provided for a portable electronic device, such as a portable computer. The drainage structure includes an inclination formed on a top surface of a body of the portable electronic device to support a keyboard device in an inclined manner so that water spilled on the keyboard device or the top surface can be expelled out of the electronic device by gravity. If desired, height adjusting units can be arranged between the keyboard device and the top surface of the body to selectively maintain the keyboard in a horizontal condition. A drain hole or groove can be selectively formed in the body of the electronic device to facilitate drainage of water.

Abstract: A dual-CPU computer-based multimedia system is provided, including a computer connected to a multimedia playing control module. The multimedia playing control module has a second CPU connected to the computer through a bus, a multimedia activation and playing system memory connected to the second CPU and storing a second operating system and a kernel program, and at least a hotkey, connected to the second CPU through a hotkey interface circuit, with each hotkey corresponding to a multimedia player. When the second PCU detects any hotkey being operated, the second PCU loads the kernel of the second operating system from the multimedia activation and playing system memory and executes the kernel. Then, the second CPU loads and executes the driver and the application program for the multimedia player corresponding to the operated hotkey.
