Abstract: System and method for backing up management components of a software-defined data center (SDDC) managed by a cloud-based service uses backup rules for the SDDC, which are used to configure a backup manager agent in the SDDC. The backup rules are then used by the backup manager agent to determine whether at least one of system logs generated by the management components in the SDDC, which are monitored by the backup manager agent, satisfies the backup rules to initiate a backup operation for at least one of the management components of the SDDC.

Abstract: Unintended current flow or plasma discharge has been observed in known illuminated electrosurgical devices having a metallic tubular heat sink surrounding a conductive electrode and an illumination element, and having a distal outer edge that abuts against the light emitting element. An insulating, shielding or other isolating element that prevents or discourages unintended plasma formation between the distal outer edge and nearby patient tissue can reduce the potential for tissue damage to a patient or injury to a surgeon.

Abstract: A system and method for polling a plurality of client devices of different types are provided. A reboot and polling tool pre-polls client devices, where the pre-poll is specific to a type of client device and identifies a state of the client devices. The reboot and polling tool then executes a script on the client devices that changes the state of the plurality of client devices. After the script is executed, the reboot and polling tool post-polls the client devices where the post-poll is specific to the type of client device and the post-poll provides information that identifies changes in the state of the client devices caused by the script.

Abstract: A subsurface continuous radioisotope environmental monitor that provides a continuous monitoring of the possible presence of radioactive species in subsurface groundwater. The detector and all supporting system elements are specifically constructed and equipped to be permanently mounted in a well or borehole to continuously detect and record radiation decay of radioactive species that are borne by subsurface water flow to that sampling area. The system operates by placing a detection element in a housing such that subsurface water that reaches the bore or well can flow in contact with the detection element. The system can employ several detection modes and materials. The detector includes SiPMs operating in a coincidence spectroscopy configuration to significantly reduce spurious signals due to thermal noise as well as increasing the total amount of signals collected.

Abstract: This document discloses system, method, and computer program product embodiments for assessing whether a vehicle that is positioned in an off-road parking area is exhibiting intent to enter the road. If the vehicle exhibits such intent, the system may forecast a trajectory for the vehicle. If the vehicle does not exhibit such intent, a trajectory forecast may not necessarily be required. The trajectory forecasts for vehicles that do exhibit such intent may then be used by an autonomous vehicle in motion planning operations.

Abstract: A fleet management system coordinates multiple autonomous vehicles (AVs) to transport a group of passengers from one location to another. A single user can submit a request to the fleet management system to provide a ride for the group, the request specifying the number of passengers and the pickup location.
