Abstract:

A computer connected to one or more networks through appropriate network interfaces is used to classify, manipulate, and/or control communications, e. g. , packets sent and/or received over the network by one or more applications executing in the computer. Each application is connected to the network through one or more sockets to enable this communication. The computer also comprises one or more rule sets of one or more rules. A socket set of one or more of the sockets is associated with only one of the rule sets. The rules in the rule set are used to control one or more of the packets communicated by the applications communicating over the socket(s) associated with the respective rule set. Rules can be added to the rule set, deleted from the rule set, or modified in order to classify, manipulate, and/or control the communication of the packets, e. g. to control the rate at which the packets are sent or to provide certain security functions.

US Classification:

514249, 51425212, 514579

Abstract:

A method for rendering a carboxyl-containing polymer surface resistant to microbial growth, the method comprising: (i) reacting the carboxyl-containing polymer surface with a metal borohydride in a solvent system comprising a water-soluble alcohol having one to three hydroxy groups and one to four carbon atoms, and optionally up to about fifty percent water, in a temperature range having a minimum of about 60 C. and a maximum of about 80 C., and for an amount of time sufficient for reducing carboxyl groups on the carboxyl-containing polymer surface to surface hydroxymethyl groups without altering the nature of the bulk of the polymer; and either: (iia) converting hydroxy groups of the surface hydroxymethyl groups to leaving groups and displacing the leaving groups with one or a combination of antimicrobial agents; or (iib) displacing the hydrogen atoms of the hydroxy groups of the surface hydroxymethyl groups with one or a combination of antimicrobial agents.
