    摘要： An invention is provided for limiting power during an unconfigured state of a USB device. The invention includes a first voltage regulator, which supplies a first voltage, in electrical communication with internal device logic of a USB device. A second voltage regulator is also included that supplies a second voltage that is higher than the first voltage. In addition, a current limiting resistor is included. The current limiting resistor is coupled to an output of the second voltage regulator and is further in electrical communication with the internal device logic of the USB device. The current limiting resistor is configured to allow a maximum current of 100 mA from being provided to the internal device logic of a USB device from the second voltage regulator.

    摘要： An Internet telephony device is provided, which comprises a voice processing unit capable of processing voice signals into electrical signals and vice versa, and a microprocessor comprising an embedded client application for communicating said electrical signals to an Internet telephony server over a network. The Internet telephony device further comprises at least one motion detector adapted to generate motion signals based on the detection of motion in the vicinity of the Internet telephony device. The motion detector is coupled to the microprocessor to determine user status of the Internet telephony device based on the motion signals.
