Abstract: A system for high pressure proppant blending includes at least one high pressure pump coupled to a high pressure flow path, the high pressure flow path entering a wellhead. The system further includes a chamber storing a mixture of proppant and compressed gas. The system also includes a high pressure nozzle. An output of the high pressure nozzle is coupled to the high pressure flow path between the at least one high pressure pump and the wellhead. The chamber is coupled to an input of the high pressure nozzle.

Abstract: A method and system for communicating audio, video, and/or control signals within a home entertainment system. A plurality of audio channels is communicated between a wireless transmitter and a wireless receiver. The wireless transmitter is located proximate to a speaker housing. In some embodiments the speaker housing also encloses a center channel loudspeaker. The center channel loudspeaker transmits an audio signal to a remote loudspeaker. An exemplary remote loudspeaker is a subwoofer loudspeaker. The subwoofer loudspeaker provides one or more received audio channels to one or more surround loudspeakers.

Abstract: A method and system for communicating audio, video, and/or control signals within a home entertainment system. One or more signals are communicated between an input device and one or more output devices via one or more networks. The output device can include loudspeakers, display devices, and headphones. In some embodiments an output device, for example a center channel loudspeaker, transmits signals to other output devices. For example, the center channel loudspeaker can transmit a combined audio signal and control signal to a remote loudspeaker over a first network and transmit a video signal to a display device over a second network. The display device displays the video signal. The networks can be wireless, wired, infrared, RF, and powerline.

Abstract: A docking station is configured to receive media in the form of audio and/or video from a portable entertainment device. The docking station transmits the received media to a remote playing device via a wired, wireless, or powerline connection. The media may include a control signal associated with the audio and/or video to control the remote playing device. In certain embodiments, the remote playing device transmits control signals to the docking station to control the portable entertainment device. In certain embodiments, the docking station electrically charges the portable entertainment device.
