Patent number: 11963850Abstract: A mechanical wound therapy (MWT) system includes a connection for a vacuum source, which is routed through an airtight covering to a porous material positioned over the wound. The porous material may be a tubing network interspaced by a netting material constructed of biologically inert or bioabsorbable material. Alternatively, the porous material may be a layered unified dressing in which layers of mesh, netting or thin perforated film are separated and fixedly attached to functional elements of the dressing (e.g., irrigation tubing) or spacers. The vacuum and irrigation systems may be completely separated. An airtight sealing layer or foldable adhesive sealing layer may seal the dressing and facilitate sealing the dressing to the wound margins. Additional modular devices such as a wound approximating system, positive pressure bladders and adjuvant therapy modules as well as enhanced monitoring technology can be added to synergistically increase the capabilities of each dressing.Type: GrantFiled: November 25, 2019Date of Patent: April 23, 2024Assignee: J&M Shuler Medical Inc.Inventors: Brett A.

Patent number: 11877523Abstract: Embodiments of a Majorana-based qubit are disclosed herein. The qubit is based on the formation of superconducting islands, some parts of which are topological (T) and some parts of which are non-topological. Also disclosed are example techniques for fabricating such qubits. In one embodiment, a semiconductor nanowire is grown, the semiconductor nanowire having a surface with an oxide layer. A dielectric insulator layer is deposited onto a portion of the oxide layer of the semiconductor nanowire, the portion being designed to operate as a non-topological segment in the quantum device. An etching process is performed on the oxide layer of the semiconductor nanowire that removes the oxide layer at the surface of the semiconductor nanowire but maintains the oxide layer in the portion having the deposited dielectric insulator layer. A superconductive layer is deposited on the surface of the semiconductor nanowire, including over the dielectric insulator layer.Type: GrantFiled: July 7, 2021Date of Patent: January 16, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Roman Lutchyn, Michael Freedman, Andrey Antipov
