Patent number: 12265606Abstract: Methods, systems, and computer program products for direct assignment of physical devices to confidential virtual machines (VMs). At a first guest privilege context of a guest partition, a direct assignment of a physical device associated with a host computer system to the guest partition is identified. The guest partition includes the first guest privilege context and a second guest privilege context, which is restricted from accessing memory associated with the first guest privilege context. The guest partition corresponds to a confidential VM, such that a memory region associated with the guest partition is inaccessible to a host operating system. It is determined, based on a policy, that the physical device is allowed to be directly assigned to the guest partition. Communication between the physical device and the second guest privilege context is permitted, such as by exposing the physical device on a virtual bus and/or forwarding an interrupt.Type: GrantFiled: September 26, 2022Date of Patent: April 1, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Jin Lin, Jason Stewart Wohlgemuth, Michael Bishop Ebersol, Aditya Bhandari, Steven Adrian West, Emily Cara Clemens, Michael Halstead Kelley, Dexuan Cui, Attilio Mainetti, Sarah Elizabeth Stephenson, Carolina Cecilia Perez-Vargas, Antoine Jean Denis Delignat-Lavaud, Kapil Vaswani, Alexander Daniel Grest, Steve Michel Pronovost, David Alan Hepkin

Patent number: 12233179Abstract: Systems and methods for autonomous sterilization of vehicles includes coded logic or processing instructions to determine (i) when sterilization should occur (or not occur), (ii) where sterilization should occur (or not occur), and/or (iii) how sterilization should occur (e.g., which method to use, how long to conduct, and/or which parameter values/settings to employ). The sterilization system may autonomously determine when it is safe to sterilize an environment/location and/or how such sterilization should be carried out. Autonomous sterilization systems and/or processes described herein may permit facilities and/or services to remain open and/or available at higher rates than current offline processes permit, thereby increasing availability.Type: GrantFiled: April 15, 2021Date of Patent: February 25, 2025Assignee: Robotic Research OpCo, LLCInventors: Alberto Daniel Lacaze, Joseph Putney, William Becker, Steve Rotundo, Karl Nicholas Murphy

Publication number: 20070112342Abstract: A method and apparatus for controlling the extent of tissue ablation are disclosed. The method utilizes delivering energy from an energy deliver device to a plurality of deployed electrodes and regulating energy delivered to the electrodes based on the temperature sensed by at least one remote elongate sensor element. A control device may be used to supply energy to the electrodes, to produce tissue ablation that advances from individual-electrode ablation regions to fill a combined-electrode ablation volume. Information from the sensor element(s) is used for determining the extent of ablation in the regions of the sensor elements. The supply of energy to the electrodes can thus be regulated to control the level and extent of tissue ablation throughout the combined-electrode volume.Type: ApplicationFiled: January 8, 2007Publication date: May 17, 2007Inventors: Rob Pearson, Steve Daniel, Daniel Balbierz, Kee Lee, Jessica Liang, Martha Getaneh

Patent number: 7110653Abstract: An optical network unit having an environmentally sealed printed circuit board arrangement within a first compartment and a signal in/out arrangement in a second compartment. The compartments are provided by two housings. Instead of replacing individual circuit boards in the case of breakdown or malfunction, replacement of the whole of the printed circuit board arrangement is necessary thereby eliminating human error and minimizing downtime. Two housings provide the two compartments. These housings are preferably mounted upon a housing mount and a carrier for the optical network unit is also preferably mounted upon the housing mount. This housing and carrier arrangement simplifies assembly and disassembly of parts of the unit for maintenance and replacement purposes.Type: GrantFiled: August 16, 2002Date of Patent: September 19, 2006Assignee: Alcatel Canada Inc.Inventors: Jay Richard Sobel, Steve Daniel Armstrong

Patent number: 6739925Abstract: A hydrodynamic device for use with a recreational water vessel such as a surfboard, disrupts a flow of water under the recreational water vessel. A channel member (12) and a fixing device (14) are attachable to an underside of the recreational water vessel. The fixing device (14) may have lugs (44) arranged to be received in corresponding recesses in the underside of the vessel. Water flowing between the underside of the vessel and the channel member (12) passes from a high water-pressure zone to a low water-pressure zone, which enhances forward thrust of the recreational water vessel in the water.Type: GrantFiled: September 25, 2002Date of Patent: May 25, 2004Inventors: Steve Daniel Burns, James Edward Salisbury
