Vorrichtung und Verfahren zum elektrischen Umschalten zwischen Peripheriegeräten

摘要

The apparatus (10) allows the connection of two peripherals to a host device through one port (14) and switching between them. The apparatus includes a sensor (16) for sensing a data signal from the second peripheral device and a switch (20) responsive to the sensor (16). The switch (20) in a default, first state connects the first peripheral device to the host device and in a second state disconnects the first peripheral device therefrom. If a second peripheral device is connected to the apparatus (10), the sensor (16) senses a data signal from the device and communicates this sensing to the switch (20). The switch (20) responds by disconnecting the first device from the host device, leaving the second device solely connected to the host device. If the second peripheral device is disconnected from the apparatus (10), the switch (20) reconnects the first peripheral device to the host device.
