System providing faster and more efficient data communication
A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine.

Pre-equalizer at the terminal to compensate for forward link distortions
Techniques are described for pre-equalization at the demodulator of a satellite receiver terminal to compensate for forward link distortions. Some satellite channel filters can manifest distortions, such as asymmetric group delay response. Such distortions can conventionally force restriction of symbol rate only to the portion of the channel bandwidth having a symmetric filter response. Embodiments include a pre-equalizer in the demodulation path that filters received downlink communications based on a set of pre-equalizer filter coefficients computed to at least partially compensate for the channel filter distortions. Some embodiments support updating the filter coefficients based on channel reassignments, and/or dynamically updating the filter coefficients based on detecting and exploiting pre-equalization frames. The pre-equalized sample stream can facilitate reliable decoding by the demodulator with an appreciably increased symbol rate and correspondingly increased forward link capacity. |

One or both cleats may be fitted with a notch to facilitate overlapping placement to accommodate large-size junction boxes. A stop tab extends laterally outwardly from each cleat and serves to limit penetration of the covering into the cavity of a junction box. One or two small removal holes are located in the body of the cover, near to the cleats, to facilitate removal from a junction box. |

Multi-quantum-reference laser frequency stabilization
A multi-quantum-reference (MQR) laser frequency stabilization system includes a laser system, an MQR system, and a controller. The laser system provides an output beam with an output frequency, and plural feedback beams with respective feedback frequencies. The feedback beams are directed to the MQR system which includes plural references, each including a respective population of quantum particles, e.g., rubidium 87 atoms, with respective resonant frequencies for respective quantum transitions. The degree to which the feedback frequencies match or deviate from the resonance frequencies can be tracked using fluorescence or other electro-magnetic radiation output from the references. The controller can stabilize the laser system output frequency based on plural reference outputs to achieve both short-term and long-term stability, e.g., in the context of an atomic clock. |
