  • Patent number: 8762695
    Abstract: In a method for registering identification information of network interface cards (NICs) in an operating system of a computing device, each of the NICs is respectively and uniquely labeled with a number. A peripheral component interconnect (PCI) device identification (ID) of each of the NICs is allocated according to the labeled number of each NIC using a basic input output system (BIOS) of the computing device when the BIOS is booted up. Then identification information of each of the NICs is registered in the operating system according to the PCI device ID of each NIC using a NIC driver of the computing device, when the NIC driver is driven by the operating system during the booting up process of the operating system.

  • Publication number: 20120155661
    Abstract: An electronic device and method for testing an audio module of a network device including establishing a first connection between an audio output interface of the electronic device and a microphone interface of the network device. First audio data of a test file is transmitted from the audio output interface to the microphone interface through the first connection. An audio card of the network device records the first audio data output by the microphone interface to generate second audio data, and transmit the second audio data to the electronic device through a network. The second audio data is compared with the first audio data in response to receiving the second audio data by the electronic device. The audio module is determined to be normal if the second audio data matches the first audio data.

  • Publication number: 20120098844
    Abstract: A refresh rate adjustment method automatically adjusts a refresh rate of a monitor connected to a computer to a default refresh rate, in response that a detected keystroke signal is a predefined keystroke signal. The method further detects a refresh rate range that is supported by the monitor, detects a new refresh rate input signal from the input device, and determines if the new refresh rate falls within the refresh rate range that is supported by the monitor. If the new refresh rate falls within the refresh rate range that is supported by the monitor, the method automatically adjusts the refresh rate of the monitor with the new refresh rate. Otherwise, the method prompts a user to input the new refresh rate again by displaying a dialog box on the monitor.

  • Publication number: 20120049651
    Abstract: A power switch control device includes a control chip connected to power switches distributed in a room, and a microcontroller connected to the control chip. When a person gets through an entry/exit door of the room, both of a first sensor fixed to an interior surface of the door and a second sensor fixed to an exterior surface of the door sense the person. By comparing record times of the two sensors, the microcontroller can determine whether the person enters or exits the room. If the person enters the room and a count value is changed to one from zero, the microcontroller sends a power-on command to the control chip to switch the power switches on. If the person exits the room and the count value is changed to zero from one, the microcontroller sends a power-off command to the control chip to switch the power switches off.
