摘要： A method and apparatus for device discovery and channel selection in a wireless networking environment are described. As part of an automatic network configuration process, a super node sequentially traverses the available channels, broadcasting discovery messages including the channel switching schedule. Wireless nodes that receive those broadcast messages switch channels in lock step with the super node, sending discovery replies on those channels over which the broadcast discovery messages are successfully received. An association is generated identifying accessible nodes and the channels through which those nodes may be accessed. An optimum channel may then be selected based on this association information. Sub-nodes may repeat the broadcast discovery messages, and relay any discovery replies to the super node. The super node may then identify sub-nodes that may be used as proxies to access nodes that would otherwise be inaccessible.

摘要： A method or system of enabling a wireless client device to select an access point based on at least two performance related parameters. A performance related parameter is a measurement of how efficiently a particular access point transfers data. By selecting an access point based on more than one performance related parameter, a wireless client device is more likely communicate with the most efficient access point. In addition, the wireless network as a whole will be more balanced and have a greater capacity if each of the wireless client devices is connected to the access point that provides the most efficient communications.

摘要： A device and method are provided for detecting and configuring a solid state dimmer when wired in series or parallel with a load powered by an alternating current (AC) input. The device can comprise a microcontroller configured to be powered by the AC input. A zero-cross detector in communication with the microcontroller is capable of detecting when an AC waveform crosses zero and generating a corresponding pulse signal when the AC waveform crosses zero. A pulse analyzer can be included and configured to determine when the zero-cross detector is generating pulses exceeding a pre-determined time length threshold that represents a serial wiring configuration.
