    摘要: A method and apparatus for facilitating direct access to computer resources by a peripheral device while the computer's CPU is in a sleeping state. A peripheral device having a circuit to detect the power management state of a central processor, a first interface to couple the device to the central processor if the circuit detects the first power management state, and a second interface to couple the device to a peripheral device if the circuit detects the second power management state.

    摘要: A peripheral device having a circuit to detect the power management state of a central processor, a first interface to receive data, and a second interface to couple the peripheral device to the central processor. The peripheral device prevents data transfers that would cause the central processor to change from a second power management state to a first power management state if the central processor is in the second power management state.

    摘要: A method and apparatus for identification of wireless devices based on signal characteristics. An embodiment of a method includes receiving a signal from a wireless device and generating a spectrogram of the received signal. The method further provides for identifying one or more regions of the spectrogram and processing the spectrogram to determine time, bandwidth, and density characteristics of the identified regions.
