A system and method is provided of synchronizing data streaming. The method can include the operation of receiving an incoming media packet having a timestamp from a media server at a client device. A further operation is synchronizing the clocks for a client device with a clock for a media server. The timestamp can be compared with a next play time for a packet. Another operation can be placing the incoming media packet into a user buffer at a playing position in the user buffer based on the next play time. The incoming media packet can then be played using a media output device accessible to an end user.

A method for detecting a load type is described. The method includes placing an electronic device in a forward phase mode. The method also includes operating a load at a maximum allowable level. The method additionally includes capturing a voltage waveform. The method further includes capturing a current waveform. The method also includes obtaining a voltage zero-cross based on the voltage waveform. The method additionally includes obtaining a current zero-cross based on the current waveform. The method further includes determining the load type based on the voltage zero-cross and the current zero-cross.

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 and apparatus for synchronizing streaming media with multiple output devices. One or more media servers serve media streams to one or more output devices (i.e., players). For playback synchronization, one output device is the “master”, whereas the remaining output devices are “slaves”. More data is requested from the media server by the “master” device to maintain a nominal buffer fill level over time. The “slave” devices receive streamed data from the media server at the rate determined by the master device's data requests, and the average rate of data flow over the streaming network is thus controlled by the frequency of the single “master” device's crystal. “Slave” devices make playback rate corrections to maintain respective buffer fill levels within upper and lower threshold levels. For slow networks, each media data packet timestamp is calculated from the time the master's buffer reaches nominal level.

A surface-mount touch panel cradle is disclosed for use in electrically controlling remote components. The surface-mount touch panel cradle comprises a surface mounted receptacle. A cradle frame can be coupled to the receptacle. A frame biasing mechanism can be configured to move the cradle frame away from the information mount to enable the touch panel to be inserted and removed from the receptacle. An electrical connection can be located within the receptacle. The electrical connection can be configured to be electrically coupled to the touch panel.
摘要:
Systems and methods for estimating the effects of a request to change power usage are described. Device data about one or more devices may be received. User behavior data about past and anticipated user behavior may be received. Effects of a request to change power usage on a power grid may be estimated using the device data and the user behavior data. Whether to send the request to change power usage may be determined based on the estimated effects.

In a method for instant messaging using a control device, a user is authenticated with an instant messenger server. A message is received. The received message includes message data from the instant messenger server. It is determined whether the message should be forwarded to the control device. If it was determined that the message should be forwarded to the control device, the received message is forwarded to the control device.
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.
