Publication number: 20250143680Abstract: A surgical instrument assembly is provided that can be equipped in a handheld surgical tool or instrument or other medical device, as well as potentially in non-medical devices, among other possible applications. In various implementations, the surgical instrument assembly has combinations of a frame body, an input body, an indexing body, a tensioning body, and a cover body. The indexing body is moveable to a multitude of indexed positions. The indexed positions constitute a use count of the surgical instrument assembly, and a final indexed position is a final use count of the surgical instrument assembly. The tensioning body is moveable to impart a first tension and a second tension to one or more transmission cables. The cover body is moveable to render a flush port inaccessible and accessible.Type: ApplicationFiled: November 4, 2024Publication date: May 8, 2025Inventors: Zachary R. Zimmerman, Matthew P.

Publication number: 20250120742Abstract: A retention assembly is provided that can be equipped in a handheld surgical tool or instrument or other medical device, as well as potentially in non-medical devices, among other possible applications. In the application of the handheld surgical instrument, the retention assembly furnishes partial or more constraint between bodies such as a handle body and a frame body, which in turn serves to partially or more constrain an end effector of the handheld surgical instrument. Such constraint at the end effector, whether partial or full, can be useful in certain scenarios amid a minimally invasive surgical (MIS) procedure such as during initial insertion of the end effector through a surgical trocar at a patient's body.Type: ApplicationFiled: October 16, 2024Publication date: April 17, 2025Inventors: Christopher Paul Huang Shu, Zachary R.

Patent number: 12223339Abstract: Techniques are described for deploying a virtualized computing environment configured in a user-specific configuration, the virtualized network function comprising a plurality of virtual machines. A solution definition file (SDF) identifies a configuration for the deployment. The SDF replaces each secret needed for the deployment with an identifier for the secret. A schema defines a format for each identifier for each secret included in the SDF and a format of the secrets. The secrets and corresponding identifiers are stored in a secure storage. The identifiers are sent to the deployed virtual machines, the identifiers being usable by the virtual machines to obtain the secrets from the secure storage.Type: GrantFiled: November 30, 2021Date of Patent: February 11, 2025Assignee: Microsoft Technology Licensing, LLCInventors: James Duncan Parsons, Peter John Whiting

Patent number: 11973651Abstract: The system described herein provides a method for deploying, managing, scaling, configuring, upgrading, and modifying large complicated systems that are made-up of many different network resources. These network resources may be virtual machines or containers. The system constructs a hierarchical SNS by building up layers from the inside of an outer SNS. The system conducts health checks at each layer to ensure the system is properly functioning and the deployment is healthy. Lastly, third party vendors input logic in each layer to identify a desired state for the system. Once the desired state is identified, each layer can determine the necessary actions to upgrade from the current state to the desired state. This system simplifies, adds efficiency, and increases security when deploying, scaling, configuring, upgrading, or modifying the system.Type: GrantFiled: June 15, 2023Date of Patent: April 30, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: James Duncan Parsons, Peter Louis White, Sunniva Rose Carter

Patent number: 11878983Abstract: A method of producing levoglucosenone from particulate cellulosic material. The method comprises forming a premix of particulate cellulosic material, water, acid and a polar organic solvent. The solvent has a higher boiling point than levoglucosenone. The pre-mix is fed into a pyrolysis reactor, such as a fluidised bed reactor, in which the pre-mix is fluidised by a fluidising gas. The reactor is maintained at a temperature within the range 250° C. to 450° C., and gaseous products and char are withdrawn from the pyrolysis reactor. Levoglucosenone and the polar organic solvent are condensed from the gaseous products, produced by the reactor.Type: GrantFiled: August 15, 2019Date of Patent: January 23, 2024Assignee: CIRCA GROUP LIMITEDInventors: Anthony James Duncan, Ebbe Jan Dommisse, Warwick Douglas Raverty

Patent number: 11831501Abstract: Techniques are described for generating a virtualized network function (VNF) descriptor (VNFD) indicative of resources for managing VNF components (VNFCs) across a plurality of virtualized infrastructure managers (VIMs) implemented in a virtualized computing environment configured in a user-specific configuration. A VNFD generator receives a solution description file (SDF) encoding user input pertaining to the user-specific configuration, and a VNFC descriptor encoding VNFC specific information. The SDF and VNFC descriptor are validated and translated to generate an abstracted VNFD that is independent of renderers implemented at the virtualized computing environment. The abstracted VNFD is translated to a VNFD that is specific to the renderers and VIM and VNFD-specific information at the virtualized computing environment.Type: GrantFiled: December 27, 2022Date of Patent: November 28, 2023Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Andrew Lee, James Duncan Parsons, Andrew Munro Caldwell, David Charles Hotham, Michael André Duppré, Philip Joel Davies, Joseph Ellis Darracott Powell

Publication number: 20230145266Abstract: A ballistic vest includes a carrier and at least two ballistic panels supported in the carrier, including a front ballistic panel and a back ballistic panel. The carrier is made from at least two layers of material including an outer layer and an inner layer that are joined to each other at the top and bottom of the vest and that are substantially open at the sides. The carrier has portions defining a left armhole and a right armhole. The two carrier layers define between them a panel space in the carrier. An upper part of the panel space is located above the bottom of the left and right armholes and a lower part of the panel space is located below the bottom of the left and right armholes.
