Abstract: An electronic device includes a housing and a power supply unit. The housing has a first side surface and a second side surface on opposite sides thereof and a receiving cavity defined therein, an inlet defined in the first side surface and an outlet defined in the second side surface. The receiving cavity is connected with the inlet and the outlet. The power supply unit is located in the receiving cavity, and a shape of the power supply unit corresponds to that of the receiving cavity.

Abstract: A computer mouse includes a casing, a skidding pad and a cushion member. The casing has a bottom surface and a side surface adjacent to a peripheral of the bottom surface. The skidding pad is applied on the bottom surface of the casing for sliding upon a working surface. The cushion member is formed at a corner defined between the bottom surface and the side surface of the casing. Additionally, when the computer mouse is stand still on the working surface, only the skidding pad is in contact with the working surface.

Abstract: A sound output device with an earphone mode and a speaker mode is provided. The sound output device changes a circuit resistance value of loudspeaker modules by adjusting a connecting state of the loudspeaker modules in the sound output device. Thus the sound output device is set to an output volume value of the earphone mode or of the speaker mode, so as to meet the requirements of the user, and to improve the convenience in use of the sound output device.

Abstract: A method for reading and writing non-standard register of standard interface device is disclosed. An input no-available parameter of standard command is set as an executive parameter. While receiving the standard command the standard interface device detects executive parameter for reading corresponding value of non-standard register and saving the value into an output register corresponding to output no-available parameter in response to the standard command. Then users can read the value of the output register to learn value of non-standard register. Moreover, by setting the input no-available parameters of standard command as executive parameter and data parameter, standard command with executive parameter and data parameter is sent into the standard interface device. Thus the standard interface device detects the executive parameter so as to write the data parameter into the non-standard register corresponding to the executive parameter.

Abstract: A method for reading non-standard register of Serial Advanced Technology Attachment (SATA) devices discloses an unused input parameter of standard command setting up as an executive parameter. While receiving the standard command, a SATA host controller converts the executive parameter and the standard command into input frame information structure (FIS) that is sent to the SATA devices for the SATA devices to detect the executive parameter for reading corresponding value of non-standard register and saving the value into an output register of the SATA devices. The value of the non-standard register is converted into output frame information structure for being sent to the SATA host controller and the value of the non-standard register is saved to the output register of the SATA host controller. Then by reading the value of the output register of the SATA host controller, the value of the non-standard register is learned.

Abstract: A method for driving a standard interface to perform nonstandard functions is proposed. It includes setting a no-available parameter of a standard command frame as an execution parameter; and sending the standard command frame with the execution parameter to the standard interface. Therein, when the standard interface finds the execution parameter, the standard interface performs a corresponding one of the nonstandard functions. Thus, on the premise that the standard interface complies with the standard interface specification, the present invention provides a provides a novel way to define the command frames for driving the standard interface to perform nonstandard functions and thereby improve the flexibility of the standard interface.
