Abstract: A computer peripheral device is provided. The computer peripheral device is adapted to be installed in an electronic device supporting signal transmission of a first signal frequency. The computer peripheral device includes a human interface device (HID) and a bridging device. The HID includes a control unit to support signal transmission of a second signal frequency. The bridging device includes a first universal serial bus (USB) interface unit and a second USB interface unit. The first USB interface unit is adapted to be electrically connected to the electronic device, and supports signal transmission of the first signal frequency. The second USB interface unit is adapted to be electrically connected to the HID. The second USB interface unit regards the HID as a communication device class (CDC) device, instructs the control unit to generate an input signal at a timing corresponding to the first signal frequency, and transmits the input signal to the electronic device.

Abstract: A control circuit for an input device including a micro-switch is provided. The control circuit includes an input circuit, a receiver circuit, a control unit, and a detecting unit. The input circuit includes a first contact and a second contact for electrically connecting to the micro-switch. The receiver circuit includes a third contact and a fourth contact for electrically connecting to the micro-switch. The control unit is electrically connected to the first contact and the third contact for providing an input signal via the first contact to the micro-switch and receiving a switching signal from the micro-switch via the third contact. The detecting unit detects a voltage of the second contact to generate a detecting signal. The control unit receives the detecting signal to determine a type of the micro-switch.

Abstract: An electrical device includes an input device, an application recorder and a control unit. The input unit is configured to receive a first enabling signal at a first time and a second enabling signal at a second time, respectively. The application recorder is configured to record the plurality of applications which have been executed by the electrical device. At the first time, the first application is the latest-executed among the plurality of applications. The control unit obtains a first metadata of a first application from the application recorder and links a first memo data input by the user to the first metadata. At the second time, the second application is the latest-executed among the plurality of applications. The control unit obtains a second metadata of a second application and links a second memo data input by the user to the second application.

Abstract: An electronic device and a method of controlling the same are provided. The electronic device includes a touch screen and a controller. The controller detects a trigger signal while the electronic device is in a user-interface lock state. When the trigger signal is detected, the controller executes a touch-gesture recording program, and receives and stores an input touch-gesture.
