Abstract: A connector assembly for connecting a peripheral device to a computer includes a male connector having a plurality of first connecting pins and a female connector having a plurality of second connecting pins. The plurality of first connecting pins is configured to connect to the peripheral device. The plurality of second connecting pins is configured to connect to the computer. The plurality of second connecting pins is defined on the first circuit board in a second row and a third row. The plurality of second connecting pins comprises a plurality of differential pairs, and each differential pair comprises two differential transmission lines. The two differential transmission lines of each of the plurality of differential pairs are defined on a single row of the second and third rows.

Abstract: A signal transmitting circuit includes a HDMI signal transmitting unit adapted to output a HDMI signal, a VGA signal transmitting unit adapted to output a VGA signal, a VGA signal processing unit, and a transmitting control unit. The VGA signal processing unit is connected to the VGA signal transmitting unit. The VGA signal processing unit is adapted to receive the VGA signal from the VGA signal transmitting unit, and include a detection signal into the VGA signal to form a combination signal. A transmitting control unit is connected to the VGA signal processing unit and the HDMI signal transmitting unit. The transmitting control unit is adapted to receive the combination signal and the VGA signal, to distinguish the combination signal and the VGA signal, and to output the combination signal and the VGA signal to the appropriate receivers.

Abstract: A power supply circuit for protecting a battery from current leakage when the battery is not in use includes a control signal input circuit and a switch circuit. The control signal input circuit receives a first control signal from a chip and output a second control signal. The switch circuit receives the second control signal and turns on or off an electronic connection between the battery and the chip. Wherein when the battery is not in use and not being charged by the adaptor, there is a possibility of current leakage from the battery. In such case, the switch circuit turns off the electronic connection between the battery and the chip, and the battery does not provide power to the chip.

Abstract: A docking station includes a multiplexer. The multiplexer includes a first input end, a second input end, and an encode system. The encode system is connected to the second input end, and configured to generate an encoding according to a connection status of the second input end. The encode system is configured to generate a first encoding, when a first peripheral device is connected to the second input end, to switch the multiplexer to a first state, in which the second input end is on and the first input end is off. The encode system is further configured to generate a second encoding, when the first peripheral device is not connected to the second input end, to switch the multiplexer to a second state, in which the second input end is off and the first input end is on.

Abstract: A connection detection circuit includes a first detection circuit and a second detection circuit. The first detection circuit includes a first comparator and a first detection pin connected to the first comparator. The first comparator is adapted to compare a first voltage level on the first detection pin with a first reference voltage. The second detection circuit includes a second detection pin. The second detection pin is adapted to connect to the first detection pin to vary the first voltage level on the first detection pin to switch an first transistor output when the connection of the first detection circuit and the second detection circuit is achieved.
