Publication number: 20240095372Abstract: Systems and techniques for offline platform information technology cyber-physical risk mitigation are described herein. System configuration data may be obtained for a platform information technology (PIT) computing system. A system model may be generated for the PIT computing system using the system configuration data. An attack path and mitigation data set may be generated from vulnerability and mitigation data. A risk profile may be generated for the PIT computing system by evaluating the attack path and mitigation data set using the system model. A security mitigation action may be automatically triggered based on a vulnerability detected in the risk profile.Type: ApplicationFiled: September 12, 2023Publication date: March 21, 2024Inventors: Ronald Fernandes, Andrew Stephenson, Richard J.

Patent number: 10857640Abstract: A lift assist and transfer assembly for lifting and moving a component through a travel distance is described. The assembly includes an overhead rail mounted to a ceiling of a work environment. The rail has a first end and a second end, corresponding to a loading area and a work area defining the travel distance.
