Abstract: An interactive control device includes a housing, a touch display panel and a face cover. The touch display panel is disposed within the housing. The face cover has a front surface and a rear surface. A first hollow configuration is formed on the front surface of the face cover, the face cover is detachably assembly with the housing and placed over the touch display panel, and a display area and a touch area of the touch display panel are limited by the first hollow configuration.

Abstract: A calibration device includes a main control unit, an interface conversion unit and an electronic load generation unit. The electronic load generation unit provides an electronic load, so that a USB control chip generates a constant load current. The USB control chip uses at least one preset conversion parameter to generate an analog-to-digital conversion value according to the constant load current. The main control unit generates a to-be-calibrated output current according to the analog-to-digital conversion value. The main control unit generates at least one calibrated conversion parameter according to the constant load current and the to-be-calibrated output current. The USB control chip uses the at least one calibrated conversion parameter to generate a calibrated analog-to-digital conversion value, so that an over current protection mechanism is accurately enabled.

Abstract: A support base includes a casing, a signal transmission module, a connection port, an audio output element and a detecting module. The support base is connected with a portable electronic device through the signal transmission module. The support base is connected with an external electronic device through the connection port. A first audio signal from the portable electronic device or a second audio signal from the external electronic device can be played by the audio output element. The detecting module detects the connection status of the support base. According to the connection status, the first audio signal or the second audio signal is controlled to be outputted from the audio output element.

Abstract: A docking device operates in an active mode or a passive mode. The docking device includes a path control module, a processing module and a switch. The processing module is connected to the switch, and the switch is connected between the path control module and the processing module. The path control module is configured to receive a signal from a host device. When the path control module does not receive the signal from the host device, the docking device operates in the active mode, and the processing module is connected to a plurality of function modules through the switch. When the path control module receives the signal from the host device, the docking device operates in the passive mode, and the path control module is connected to the function modules through the switch.

Abstract: Disclosed is a USB docking station and a control method thereof. The USB docking station comprises a micro controller, a first signal multiplexer and a second signal multiplexer, a video signal processor, and a video signal converter. The first signal multiplexer chooses and outputs a first video signal from a first data signal output from a first electronic device. The second signal multiplexer chooses and outputs a second video signal from a second data signal output from a second electronic device. According to a first control signal from the first electronic device or a second control signal from the second electronic device, the micro controller controls the video signal processor to process the first video signal or the second video signal. The video signal converter converts the processed first video signal or the processed second video signal to a video output signal for displaying.
