摘要： A power supply circuit for supplying electric power to a portable computer includes a main battery, a first control circuit, a backup battery and a second control circuit. The main battery includes a first output terminal and a second output terminal shorter than the first output terminal. When the main battery is drawn out of the portable computer, a disconnection between the second output terminal and the portable computer occurs earlier than a disconnection between the first output terminal and the portable computer to from a time difference between the two disconnections. During this time difference, the main battery is controlled by the first control circuit to change from supplying electric power to the portable computer to not supplying electric power to the portable computer, and the backup battery is controlled by the second control circuit to supply electric power to the portable computer instead of the main battery.
摘要翻译：用于向便携式计算机供电的电源电路包括主电池，第一控制电路，备用电池和第二控制电路。主电池包括比第一输出端子短的第一输出端子和第二输出端子。当主电池从便携式计算机中拉出时，第二输出端和便携式计算机之间的断开比第一输出端和便携式计算机之间的断开早于两个断开之间的时间差发生。在该时间差期间，主电池由第一控制电路控制，从提供电力切换到便携式计算机，以不向便携式计算机供电，备用电池由第二控制电路控制以提供电力到便携式计算机而不是主电池。

摘要： A double network physical isolation circuit includes a north bridge chip, a bus switch circuit, a first memory, and a second memory. The bus switch circuit includes a first and a second bus switch chip. The first and second memories are connected to different networks. The north bridge chip is connected to the first and second memory. When the bus switch circuit receives a high level signal, the first input pin of the first bus switch chip is in electrical communication with the first output pin of the first bus switch chip, and the first memory is activated. The second memory is grounded through the second bus switch chip. When the bus switch circuit receives a low level signal, the second input pin is in electrical communication with the second output pin of the first bus switch chip, and the second memory is activated. The first memory is grounded through the second bus switch chip.
摘要翻译：双网络物理隔离电路包括北桥芯片，总线开关电路，第一存储器和第二存储器。总线开关电路包括第一和第二总线开关芯片。第一和第二存储器连接到不同的网络。北桥芯片连接到第一和第二存储器。当总线开关电路接收到高电平信号时，第一总线开关芯片的第一输入引脚与第一总线开关芯片的第一输出引脚电连通，并且第一存储器被激活。第二个存储器通过第二个总线开关芯片接地。当总线开关电路接收到低电平信号时，第二输入引脚与第一总线开关芯片的第二输出引脚电连接，第二存储器被激活。第一个存储器通过第二个总线开关芯片接地。
