Abstract: A driving module including a voltage mode driver and a current mode driver is provided. The voltage mode driver converts a positive input signal to a positive output signal at a positive output terminal, and converts a negative input signal to a negative output signal at a negative output terminal. The current mode driver includes a first current source, a second current source, and a third current source. The first current source provides a first current to one of the positive output terminal and the negative output terminal. The second current source provides a second current to one of the positive output terminal and the negative output terminal. The third current source provides a third current to one of the positive output terminal and the negative output terminal.

Abstract: A bandgap module and a linear regulator are provided. The linear regulator includes the bandgap module and an error amplifier. The voltage supply voltage includes a bandgap circuit, a lowpass filter, and a start-up module. The voltage supply voltage generates a bandgap voltage. The lowpass filter filters the bandgap voltage and generates a reference voltage accordingly. The start-up module includes a first start-up circuit and a second start-up circuit. The bandgap voltage is increased to a predefined value when the bandgap module operates in a first phase. The bandgap voltage maintains at the predefined value when the bandgap module operates in a second phase. The second phase is after the first phase.

Abstract: A card-type storage device includes a processing chip and a memory module. The processing chip is selectively operated in a data accessing mode or a data uploading mode. The memory module is electrically connected with the processing chip. A first data set generated by the medical device at a first time point and a second data set generated by the medical device at a second time point are stored in the memory module. In the data accessing mode, a first storage list is established by the processing chip according to the first data set, and the first storage list is updated as a second storage list according to the second data set. If the processing chip judges that the second data set satisfies a predetermined condition, the processing chip enters the data uploading mode.

Abstract: A virtual private network connection method and a memory card device using the virtual private network connection method are provided. Firstly, a virtual private network connection application program is provided. Then, the virtual private network connection application program is loaded in a memory card device. Then, the memory card device is installed in a medical device. After the virtual private network connection application program is executed and the memory card device is connected to a virtual private network server according to a connection request, the data from the medical device is transmitted to the virtual private network server through the memory card device. In such way, the data will not be attacked by malware and stolen by a third-party manufacturer during the transmission process.

Abstract: A card adapter device includes a card slot for receiving a micro SD card therein; a SD interface for coupling electrically to a portable electronic device; a processing chip including a dynamic switch coupled electrically to the card slot and the SD interface, and a processor unit coupled electrically to the dynamic switch; and a wireless transmission/reception interface coupled electrically to the dynamic switch. Upon receiving a first signal from the wireless transmission/reception interface, the dynamic switch detects an operation mode of the SD interface and upon detecting that the SD interface is in an idle mode, the processor unit converts the dynamic switch to be coupled electrically to the wireless transmission/reception interface, thereby enabling the dynamic switch to transfer the first signal to the card slot, which, in turn, enables the wireless transmission/reception interface to access into the SD card.

Abstract: A multimedia storage card system includes a memory card; a dynamic switch coupled electrically and communicatively to the memory card; a first accessor coupled electrically and communicatively to the dynamic switch for accessing to the memory card, thereby storing data into and retrieving data from the memory card; and a second accessor coupled electrically and communicatively to the dynamic switch. Upon receipt of a first access signal transmitted from the second accessor, the dynamic switch determines whether the first accessor is in an idle condition. Upon detecting the first accessor is in the idle condition, the dynamic switch is switched to and in communication link with the second accessor, thereby transmitting the first access signal to the memory card and enabling the second accessor to access the memory card in order to store data into and retrieving data from the memory card.
