Patent number: 11917259Abstract: A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.Type: GrantFiled: November 19, 2020Date of Patent: February 27, 2024Assignee: ARRIS Enterprises LLCInventors: Ayham Al-Banna, Michael J.

Patent number: 8156065Abstract: A system is provided for managing a data structure based variable rules engine. The system includes a processor, a set of questions, a variables data structure comprising values and a set of variables, a results data structure comprising a set of requirements, a user interface, and a rules engine. The user interface outputs the set of questions and receives responses to the set of questions. The rules engine, when executed by the processor, assigns results to the set of variables by combining the responses with the values in the variables data structure, and determines whether the results meet the set of requirements in a results data structure. The set of questions, values, responses, and results are associated with a plurality of time frames. The user interface also outputs the results for the plurality of time frames in response to a determination that the results meet the set of requirements.Type: GrantFiled: June 30, 2008Date of Patent: April 10, 2012Assignee: Sprint Communications Company L.P.Inventors: Robert C.

Patent number: 7985413Abstract: Microbiological control is achieved by continuously and inexpensively dosing water in contact with biofilm, or that comes into contact with biofilm, using a highly effective biocide that provides very effective microbiocidal control of planktonic microorganisms and of biofilm species, even where the biofilm infestations have been in existence for long periods of time and thus have encased themselves in a substantial quantity of slimy defensive polysaccharide layers or films. In addition, the biocide used makes possible significant reduction in copper and/or iron surfaces in contact with the water as compared to N,N?-bromochloro-5,5-dimethyl hydantoin. Still other advantages are made possible by the described technology.Type: GrantFiled: March 5, 2009Date of Patent: July 26, 2011Assignee: Albemarle CorporationInventors: Jonathan N.
