    摘要: A method and apparatus for automatically transferring control of a portable radio communication device (101) having an internal processor (108) and a first data port (118) comprise transferring (412, 414) control from the internal processor (108) to an external computer (103), the external computer (103) having a second data port (128). In the portable radio communication device (101) the internal processor (108) detects (406) a signal at the first data port (118), the signal indicating that the external computer (103) is coupled to the portable radio communication device (101) through the first and second data ports (118, 128). In response, the internal processor (108) transfers (412, 414) control of the portable radio communication device (101) from the internal processor (108) to the external computer (103).

    摘要: An electronic device having electronic circuitry powered by a battery and having an interface for interactively coupling the electronic device to a host device, for switching the power source by which power is supplied to the electronic circuitry, and by determining (410) an interface status as being coupled to or detached from the host device. In response to determining (410) that the interface is coupled to the host device, the electronic circuit is coupled (415) to the interface such that power is supplied to the electronic circuitry from the host device. In response to determining (410) that the interface is detached from the host device, the electronic circuit is coupled (420) to the battery.
