Patent number: 11870814Abstract: Systems and methods for a unified, cloud-managed platform for controlling enterprise network security are provided. According to one embodiment, a network of an enterprise is protected by a cloud-managed platform. An underlying architecture of the cloud-managed platform is abstracted by providing a portal through which modifications to security policies are expressed as business requirements of the enterprise. The security policies are automatically enforced regardless of location or endpoint. A policy digest, including information regarding the modifications and formatted according to a predefined format, generated and locally queued by the portal is retrieved.Type: GrantFiled: December 2, 2021Date of Patent: January 9, 2024Assignee: Fortinet, Inc.Inventors: Anurag Jain, Kenneth Ammon, Thomas Cross, Michael C.

Publication number: 20230343543Abstract: A bearing structure for an X-ray tube is provided that includes a journal bearing shaft with a radially protruding thrust bearing encased within a bearing sleeve, one of which rotates relative to the other. The stationary component, e.g., the journal bearing and/or the thrust bearing includes at least one vent groove formed therein that improves the ability of the journal bearing structure to enable gases trapped by the liquid metal within the bearing assembly to escape through the vent groove to the exterior of the X-ray tube. By adding a strategically located channel or vent groove of sufficient size in at least one of the journal bearing or the thrust bearing, the pressures resisted by the seal created between the liquid metal and the vent groove(s) in the bearing components is significantly reduced, allowing escape of the gases to avoid detrimental effects to the operation of the X-ray tube, while maintaining the load carrying capacity of the bearing assembly.Type: ApplicationFiled: May 1, 2023Publication date: October 26, 2023Inventors: Ian Strider Hunt, Andrew Thomas Cross

Patent number: 11683919Abstract: A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.Type: GrantFiled: August 11, 2021Date of Patent: June 20, 2023Assignee: General Electric CompanyInventors: Karthik Bodla, Nathaniel Benedict Hawes, Brian Magann Rush, Weijun Yin, Andrew Thomas Cross
