  • Publication number: 20180023217
    Abstract: Fibers for generating antimicrobial activity are described. The fibers comprise an enzyme that is able to convert a substrate to release hydrogen peroxide, and an unrefined natural substance that includes a substrate for the enzyme, wherein the enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the unrefined natural substance. In the presence of sufficient free water, the enzyme converts the substrate to release hydrogen peroxide, which is effective against a wide range of microbes. Wound dressings and compositions comprising the fibers are also described, as is use of the fibers, wound dressings and compositions, particularly for wound healing.

  • Publication number: 20170266240
    Abstract: Compositions for prevention and treatment of microbial infectious, such as microbial infections that comprise a biofilm, or a microbe that is capable of forming a biofilm are described. The compositions comprise an enzyme that is able to convert a substrate to release hydrogen peroxide and a substance that includes a substrate for the enzyme. The enzyme is additional to any enzyme activity able to convert the substrate to release hydrogen peroxide that may be present in the substance. The substance may be an unrefined natural substance or a substance that includes a purified substrate for the enzyme.

  • Patent number: 9352503
    Abstract: According to embodiments, there is provided a method (300) of controlling a first melt accumulator (121). The first melt accumulator (121) is part of an injection unit (100), the injection unit (100) including an extruder (102) for preparing molding material and a second melt accumulator (123). The first melt accumulator (121) and the second melt accumulator (123) are configured to sequentially receive molding material from the extruder (102). The extruder (102) is being operable to produce molding material in at least near continuous manner, both the first melt accumulator (121) and the second melt accumulator (123) being associated with a respective shot size set-point. The method comprises detecting (310) an indication of an out-of-boundary condition associated with operation the first melt accumulator (121); responsive to said detecting (310), controlling (320) the first melt accumulator (121) to continue accepting molding material beyond its respective shot size set-point.

  • Publication number: 20120179288
    Abstract: A method (300) is provided for controlling an injection unit (100) having a first sub-assembly and a second sub-assembly, first and second sub-assemblies being functionally identical units. The method (300) includes the steps of appreciating an operational parameter for each of the first and second sub-assemblies, appreciating a target set point (146) associated with operating each of the first and second sub-assemblies, and when the operational parameter for at least one of the first and second sub-assemblies differs from the target set point (146), adjusting the operation of the at least one sub-assembly towards the target set point (146) by a control action. The adaptive control regulator (148) is operable to modify the control law of one of the first and second sub-assemblies so that the first and second sub-assemblies have substantially equal performance.

  • Publication number: 20090043621
    Abstract: The invention is an application for teams of information workers, their managers, and human resources professionals to evaluate and raise performance based on communication metrics and norms of behavior within a team. A model and management Web pages enable users to collectively set norms of behavior, communicate, make decisions, set roles and goals, receive evaluations according to their norms, and in other ways conduct interpersonal relations in a business context. Modules acquiring data from email and document management systems, groupware, directories, and other information sources are included. Said information is joined with the invention's internally generated data. An expert system generates observations and advice permitting the team to more appropriately deploy information, adhere more closely to its norms, and lessen stress caused by interpersonal friction. Management is provided a means of assessing teams, setting policies, and defining parametric ranges for norms.
