  • Patent number: 11917259
    Abstract: 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.

  • Patent number: 8156065
    Abstract: 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.

  • Patent number: 7985413
    Abstract: 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.

  • Patent number: 7371397
    Abstract: Microbiological control in aqueous media and/or eradication or reduction of biofilm on a surface in contact with such media is achieved by introducing into the aqueous medium a microbiocidally effective quantity of one or more 1,3-dibromo-5,5-dialkylhydantoins where one of the alkyls is methyl and the other is a C1-4 alkyl, wherein (i) the molar quantity of 1,3-dibromo-5,5-dialkylhydantoin introduced is less than the molar quantity of N,N?-bromochloro-5,5-dimethylhydantoin that would be required to effect the same degree of microbiological control in that medium, (ii) the molar quantity of the 1,3-dibromo-5,5-dialkylhydantoin introduced releases an amount of “free chlorine” that is greater than the amount of “free chlorine” that would be released in that medium by an equimolar quantity of N,N?-bromochloro-5,5-dimethylhydantoin, and (iii) the amount of “free chlorine” released by the quantity of the 1,3-dibromo-5,5-dialkylhydantoin introduced is greater than the amount of “free chlorine” that could be predicte

  • Patent number: 6565868
    Abstract: Microbiological control in water systems is achieved with an amount,of 1,3-dibromo-5,5-dimethylhydantoin that is less than the amount of N,N′-bromochloro-5,5-dimethylhydantoin required to achieve the same degree of microbiological control. The methods of combating Escherichia coli and/or Enterococcus faecium in an aqueous medium, and biofilms such as formed by Pseudomonas aeruginosa on surfaces contacted by the aqueous medium, involve introducing into the medium a biocidally effective amount of 1,3-dibromo-5,5-dimethylhydantoin. A microbiological control agent for use in water in accordance with U.S. Environmental Protection Agency regulations is purveyed in containers of a water control agent comprising 1,3-dibromo-5,5-dimethylhydantoin, which containers bear a label having thereon dosage levels pursuant to requirements promulgated by the U.S. Environmental Protection Agency. The 1,3-dibromo-5,5-dimethylhydantoin is used or purveyed either as a product having a large average particle size (e.g.
