Patent number: 11982230Abstract: A thermal management system for an aircraft comprises a first gas turbine engine, a first thermal bus, a first heat exchanger, and a chiller. The first thermal bus comprises a first heat transfer fluid, with the first heat transfer fluid being in fluid communication, in a closed loop flow sequence, between the first gas turbine engine, the first heat exchanger, and the chiller. Waste heat energy generated by the first gas turbine engine, is transferred to the first heat transfer fluid. The chiller is configured to lower a temperature of the first heat transfer fluid prior to the first heat transfer fluid being circulated through the gas turbine engine. The first heat exchanger is configured to transfer the waste heat energy from the first heat transfer fluid to a dissipation medium.Type: GrantFiled: August 14, 2023Date of Patent: May 14, 2024Assignee: ROLLS-ROYCE plcInventors: Paul R Davies, David A Jones, Alexander T Joyce, Richard G Mochrie

Publication number: 20240077021Abstract: A thermal management system for an aircraft includes a first gas turbine engine, one or more first electric machines rotatably coupled to the first gas turbine engine, a first thermal bus, and a first heat exchanger. Waste heat energy generated by at least one first gas turbine engine, and first electric machine, transfers to the first heat transfer fluid. The first heat exchanger directs a first proportion of the first heat transfer fluid through a first heat dissipation portion wherein a first proportion of the waste heat energy transfers to a first dissipation medium dependent on the first dissipation medium temperature and mass flow rate. The first heat exchanger directs a second proportion of the first heat transfer fluid through a second heat dissipation portion wherein the second proportion of waste heat energy transfers to a second dissipation medium dependent on the second dissipation medium temperature and mass flow rate.Type: ApplicationFiled: August 14, 2023Publication date: March 7, 2024Applicant: ROLLS-ROYCE plcInventors: Paul R DAVIES, Richard G MOCHRIE, David A JONES

Patent number: 11452291Abstract: One aspect of the present invention is directed to a composition. The composition includes a dispersion inducer comprising: H3C—(CH2)n—CHmCHmR, where is a single or double carbon-carbon bond, m is 1 or 2, n is 2 to 15, and R is a carboxylic acid, a salt, an ester, or an amide, where the ester or amide is an isostere or biostere of the carboxylic acid. The composition additionally contains an additive component selected from one or more of the group consisting of biocides, surfactants, antibiotics, antiseptics, detergents, chelating agents, virulence factor inhibitors, gels, polymers, pastes, edible products, and chewable products. The composition is formulated so that when it is contacted with a biofilm produced by a microorganism, where the biofilm comprises a matrix and microorganism on a surface, the dispersion inducer selectively acts on the microorganism and has a suitable biological response without a required direct effect on the matrix to disperse the biofilm.Type: GrantFiled: May 13, 2020Date of Patent: September 27, 2022Assignee: The Research Foundation for The State UniversityInventor: David G.

Patent number: 11048491Abstract: On-demand cloud-based staging environments can be rapidly created as mirrors of a production environment. By defaulting to the production environment's parameters but allowing the user to edit parameters before creating the new cloud-based staging environment, much of the work of creating staging environments can be automated. Users can create staging environments quickly and easily, so that environments can be used for a single project and dismissed, instead of having to maintain them and continuously synchronize them with changes in the production environment.Type: GrantFiled: May 11, 2020Date of Patent: June 29, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Joseph G. Davies, Tracy D. Paddock, Kelley D. Vice

Patent number: 10108440Abstract: An interactive troubleshooting system is described herein that provides a dynamically changing user interface that readers click through to solve problems. Each click changes the display of the flowchart so that irrelevant troubleshooting options are unavailable and the reader's path through the overall flowchart is clearly shown. By showing the path, the reader can see the process and the interrelationships between system components and understand more deeply the troubleshooting process beyond the step-by-step troubleshooting tasks. The interactive troubleshooting system clearly displays a path taken through the flowchart, and reduces visual clutter. Upon following a path, sections of the flowchart that cannot be followed due to the steps taken are made unavailable. The interactive troubleshooting system provides a visual indication of areas of troubleshooting focus. The system can record the user's path through the flowchart.Type: GrantFiled: November 24, 2010Date of Patent: October 23, 2018Assignee: Microsoft Technology Licensing, LLCInventor: Joseph G Davies

Publication number: 20150096888Abstract: A blood glucose test device with viewing lens seal includes a meter body rigid portion of a first polymeric material and an opening. A resilient portion of a second polymeric material more compressible than the first polymeric material integrally connected to the rigid portion defines a rigid portion outer covering. A resilient portion edge extends beyond the rigid portion and partially into the opening about a perimeter of the opening. A transparent polymeric material lens has an outer perimeter surface in contact with the resilient portion edge. Multiple flexible arms extending from the lens each have a hook member. Each hook member engages a receiving member positioned in a meter body and is retained by multiple backup ribs. Hook member engagement at a locking position pulls the lens toward the edge partially compressing the second polymeric material and creating a fluid seal between the perimeter surface and edge.Type: ApplicationFiled: October 7, 2013Publication date: April 9, 2015Applicant: Roche Diagnostics Operations, Inc.Inventors: Christopher L.

Patent number: 8658108Abstract: A limited-use blood glucose meter includes a printed circuit board assembly that includes a power source, a strip port, a strip reading device, a controller device, a bi-stable display, and a display controller. The strip reading measures a reaction between a blood sample present on the blood glucose test strip and the blood glucose reagent, generates a blood glucose signal, and calculates a blood glucose level. The controller device receives the blood glucose level from the strip reading device. The controller device provides display instructions to the display controller and the display controller provides drive voltages to the bi-stable segments such that the bi-stable segments persistently display the most-recent blood glucose level. The strip reading device performs a predetermined number of blood glucose tests and calculates a blood glucose level only for blood glucose strips associated with the disposable blood glucose meter.Type: GrantFiled: September 1, 2010Date of Patent: February 25, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Matthew C.
