Patent number: 11938045Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.Type: GrantFiled: November 23, 2022Date of Patent: March 26, 2024Assignees: United States Government As Represented By The Department Of Veterans Affairs, Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.

Patent number: 11853669Abstract: A logic block can be relocated without recompilation from a first area to a second area on a field-programmable gate array (FPGA) if the pattern of fabric tiles in the second area is the same as the pattern of fabric tiles in the first area, and if the two areas have the same dimensions. The design system runs synthesis, placement, and routing on a partition of a design at a first location, exports that partition to a persistent on-disk database, imports one or multiple copies of the partition into a larger design, and moves one or more of the copies from the first area to a target area in the larger design. The compatibility of the second area may be identified based on fabric tile signatures of the first area and the second area.Type: GrantFiled: November 22, 2021Date of Patent: December 26, 2023Assignee: Achronix Semiconductor CorporationInventors: Michael Riepe, Kamal Choundhary, Amit Singh, Shirish Jawale, Karl Koehler, Simon Longcroft, Scott Senst, Clark Hilbert, Kent Orthner

Patent number: 8299157Abstract: The invention discloses dispersions of preferably modified strontium carbonate in organic liquids, for example in alcohols, ketones or particularly methylene chloride. The dispersions are usable for the preparation of polymers which have reduced birefringence or no birefringence and are therefore suitable for optical applications. The powder obtainable after the removal of the organic liquid can surprisingly be converted back to a dispersion with little energy.Type: GrantFiled: August 9, 2005Date of Patent: October 30, 2012Assignee: Solvay Infra Bad Hoenningen GmbHInventors: Karl Koehler, Ferdinand Hardinghaus

Publication number: 20100197838Abstract: The invention discloses polymeric esters of terephthalic acid with deagglomerated barium sulphate having an average primary particle size of less than 0.5 ?m, containing a crystallization inhibitor and being coated with a dispersant, as filler. The dispersant has preferably reactive groups which are able to interact with the surface of the barium sulphate; particular preference is given to dispersants which are able to endow the barium sulphate with a hydrophilic surface and have reactive groups for coupling to or into polymers. Also disclosed is a corresponding precursor based on macrocyclic oligoesters which comprise such barium sulphate.Type: ApplicationFiled: June 2, 2006Publication date: August 5, 2010Applicant: SOLVAY INFRA BAD HOENNINGENInventors: Karl Koehler, Ferdinand Hardinghaus, Jai-Won Park, David-Christopher Glende, Klaus Nietzel

Publication number: 20090163638Abstract: The invention discloses a dispersion of deagglomerated barium sulphate having an average primary particle size of <0.5 ?m and coated with a dispersant in defined organic solvents, especially halogenated solvents such as dichloromethane. The dispersant preferably has reactive groups which are able to interact with the surface of the barium sulphate; particularly preferred dispersants are those which are able to endow the barium sulphate with a hydrophilic surface and which have reactive groups for coupling to or into polymers. The dispersion lends itself very well to incorporation into polymers such as acrylates, methacrylates, or particularly into hydrophobic polymers such as polycarbonate, or precursors thereof.Type: ApplicationFiled: June 2, 2006Publication date: June 25, 2009Applicant: Solvay Infra Bad Hoenningen GmbHInventors: Ferdinand Hardinghaus, Karl Köhler
