Abstract: In one example, an apparatus, by a processor, can identify a number of modems in each bonding group of a plurality of bonding groups, resulting in a first data structure. The apparatus can also determine a configuration for each bonding group of the plurality of bonding groups, resulting in a second data structure. The apparatus can also determine channel load for each channel of a plurality of channels, according to the first data structure and the second data structure, resulting in a third data structure.

Abstract: One embodiment of the invention includes a coax media converter (CMC) system communicatively coupled to at least one modem in a network system. The system includes a frequency reference configured to generate a clock signal in a local time domain. The system also includes a scheduling processor configured to extract a bandwidth allocation message from a data stream and to re-stamp each of at least one timestamp in the bandwidth allocation message in the local time domain based on the clock signal to generate a corresponding updated bandwidth allocation message comprising a respective at least one re-stamped timestamp. The system further includes a downstream physical interface configured to transmit the updated bandwidth allocation message to the at least one modem to schedule upstream burst transmissions from the respective at least modem based on the at least one re-stamped timestamp.

Abstract: The present invention relates to new processes for regenerating oxidized interstitial metal hydride containing catalysts prior to the use of such catalysts in a hydroprocessing process. Interstitial metal hydride containing catalysts are easily oxidized in the environment and once oxidized, the hydroprocessing activity of the interstitial metal hydrides is most often severely diminished and this lost activity due to oxidization of the iMeH is not susceptible to recovery under hydroprocessing conditions. As a result, these catalysts in the present art require considerable special handling in inert environments all through processes from fabrication, shipping, loading, use, and maintenance of the catalyst systems to protect the activity of the interstitial metal hydride components.

Abstract: Transesterification, esterification, and esterification-transesterification (both one-step and two-step) for producing biofuels. The process may be enhanced by one or more of the following: 1) applying microwave or RF energy; 2) passing reactants over a heterogeneous catalyst at sufficiently high velocity to achieve high shear conditions; 3) emulsifying reactants with a homogeneous catalyst; or 4) maintaining the reaction at a pressure at or above autogeneous pressure. Enhanced processes using one or more of these steps can result in higher process rates, higher conversion levels, or both.

Abstract: The present invention relates to novel interstitial metal hydrides and catalyst containing interstitial metal hydrides that are resistant to oxidation and resultant loss of catalytic activity. The processes of the present invention include use of these improved, oxidation resistant interstitial metal hydride compositions for improved overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams.

Abstract: The present invention relates to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride containing catalyst and hydrogen at process conditions of at least 400 psig pressure and temperatures of at least 200° C. These processes use interstitial metal hydrides that possess significant hydrogen capacities and high hydrogen kinetics rate properties. The catalysts and processes of the present invention may be used with or without radio frequency or microwave energy and are preferably run under conditions of high hydrogen partial pressure above about 350 psia. The catalysts and processes of the present invention can improve overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams as compared to processes of the prior art operated under similar conditions.
