  • METHODS FOR DETERMINING AIR RELEASE PERFORMANCE OF LUBRICATING OILS
    Publication number: 20210325360
    Abstract: Provided is a method for determining air release performance of a lubricating oil. The method involves determining air release time of the lubricating oil in accordance with ASTM D3427 at a designated temperature; determining surface tension of the lubricating oil at the temperature used in ASTM D3427; determining kinematic viscosity of the lubricating oil in accordance with ASTM D445 at the temperature used in ASTM 3427; and utilizing the surface tension, ASTM D3427 air release time, and ASTM D445 kinematic viscosity to determine air release performance of the lubricating oil. Surface tension is correlated with ASTM D3427 air release time at an ASTM D445 kinematic viscosity of at least about 30 cSt. The method has higher measurement sensitivity and reproducibility/repeatability than ASTM D3427.

  • DISTRIBUTED DIGITAL SECURITY SYSTEM
    Publication number: 20210326452
    Abstract: A distributed security system can include instances of a compute engine that can execute either locally in security agents on client devices or as cloud instances in a security network. Event data can be processed by elements of the distributed security system according to centrally-defined ontological definitions and/or configurations. Bounding managers of local security agents can control how much event data is sent to the security network. A storage engine in the security network can store event data received from client devices, can route event data to other elements of the security network, including cloud instances of the compute engine. An experimentation engine of the security network can also at least temporarily adjust other elements of the distributed security system during experiments or tests.

  • Systems and Methods for Mobile Aerial Flight Planning and Image Capturing Based on Structure Footprints
    Publication number: 20210327283
    Abstract: A system and method for flight planning for an unmanned aircraft. The system generates an aerial imagery map of a capture area and determines a footprint of a structure present in the capture area by marking the structure. The system determines a difference between a takeoff elevation of the unmanned aircraft and a predetermined elevation above a center of the structure and calibrates the difference between the takeoff elevation of the unmanned aircraft and the predetermined elevation above the center of the structure. The system determines, based on the calibration, a flight path elevation of the unmanned aircraft to capture images of the structure. The system generates a flight plan based on criteria for capturing the images of the structure and executes the flight plan.
