  • Publication number: 20190273987
    Abstract: The invention relates to a sound processing node for an arrangement of sound processing nodes, the sound processing nodes being configured to receive a plurality of sound signals, wherein the sound processing node comprises a processor configured to generate an output signal on the basis of the plurality of sound signals weighted by a plurality of beamforming weights, wherein the processor is configured to adaptively determine the plurality of beamforming weights on the basis of an adaptive linearly constrained minimum variance beamformer using a transformed version of a least mean squares formulation of a constrained gradient descent approach, wherein the transformed version of the least mean squares formulation of the constrained gradient descent approach is based on a transformation of the least mean squares formulation of the constrained gradient descent approach to the dual domain.

  • Publication number: 20190235277
    Abstract: The invention is generally related to a soft contact lens which comprises a hydrogel lens body and a coating of a hydrophilic copolymer thereon and to a method for producing the same. The hydrogel lens body comprises or is made of a polymeric material having 1,2- and/or 1,3-diol moieties, and the hydrophilic copolymer comprises arylborono-containing repeating units each having a boronic acid group. The coating is covalently-attached to the hydrogel lens body through cyclic boronic ester linkages each formed between one boronic acid group and one 1,2-diol or 1,3-diol group. The soft contact lens has a surface lubricity higher than the surface lubricity of the lens body.

  • Patent number: 9812024
    Abstract: The present invention helps generate connected communities of students and educators through access to an increased pool of granular learning resources that benefit from standardization of formats for creating and utilizing individual discussions on individual topics. The present invention also circumvents the complexity of existing repository systems by creating a standard platform format. Because this format is de facto implemented for any educator using the platform, standardized question types (e.g., discussion types or topic types) become functionally interchangeable notwithstanding any particular individuals utilizing the invention. The interchangeability of individual topics allows for creation of a global “topic library,” which may be made available to any educator using the system.

  • Publication number: 20160322942
    Abstract: Some embodiments of the present invention provided an impedance-transforming arrangement comprising a plurality of microwave power transistors 41, and at least one intermediate impedance-transforming or matching device 30. The matching device comprises a plurality of elongate microwave transmission lines 31 provided in or on at least one dielectric substrate 32, extending across or through the dielectric substrate. The microwave transmission lines are coupled at one end to the gate pads 47 of the transistor and at the input ends to a signal input terminal for the transmission line. The transmission lines are substantially directly coupled to one another by means of resistive elements 35 providing a current flow path between the two transmission lines in order to reduce any residual tendency to instability caused by manufacturing variations or misalignment in the assembly process.

  • Publication number: 20160063787
    Abstract: Embodiments of the present invention facilitate the solicitation of user input while allowing for dynamic changes to that input while concurrently ranking the same. Ranking occurs in real-time and allows for a user to alter their contribution or vote until the close of a contribution period allowing real-time influences to be taken into account. Contributions may be provided in response to or as a part of a template driven nomination process. Solicitations of input may occur in the context of a pre-defined slate of options for voting, nominating certain options for a subsequent or concurrent voting process, or choosing/suggest more than one option such as the best of a slate of options or the individual ranking of a slate of options. Embodiments of the present invention capture all user nominations or suggestions while simultaneously providing the real-time ranking and dynamic re-ranking of those nominations or suggestions.
