    • This invention includes a universal base unit having a plurality of cables, each corresponding to a unique electronic host device. The cable is manufactured such that the ground connection of the electronic host device is routed to one of a plurality of identification pins. In one embodiment, the identification pins are coupled to a plurality of current sense resistors. When the cable is coupled serially between the electronic device and the universal base unit, the universal base unit identifies the unique electronic device by sensing which resistor is connected to the ground of the electronic host. In another embodiment, pull-up resistors are used instead of current sense resistors. The system allows a user to carry a single power supply or universal base unit with multiple cables as opposed to having to transport a different accessory for each electronic device.
    • 本发明包括具有多个电缆的通用基座单元,每个电缆对应于唯一的电子主机设备。 电缆被制造成使得电子主机设备的接地连接被路由到多个识别引脚之一。 在一个实施例中,识别引脚耦合到多个电流检测电阻器。 当电缆在电子设备和通用基座单元之间串联耦合时,通用基座单元通过感测哪个电阻器连接到电子主机的地面来识别独特的电子设备。 在另一实施例中,使用上拉电阻代替电流检测电阻。 该系统允许用户携带具有多根电缆的单个电源或通用基座单元,而不必为每个电子设备运输不同的附件。
