Publication number: 20240095351Abstract: In one set of embodiments, an enhanced next generation anti-virus (NGAV) system is provided. In certain embodiments, this system includes a hypervisor-level agent that backs up VM data only when an instance of a guest application running in the VM has been flagged by the NGAV system as being potentially malicious (rather than on a constant, proactive basis). Further, the hypervisor-level agent performs this backup only with respect to data modified by that specific guest application instance (rather than backing up all data modified by the VM) and writes the backed-up data to a secure storage location which is inaccessible to the guest. The combination of these features addresses many of the problems and inefficiencies of existing NGAV systems.Type: ApplicationFiled: September 19, 2022Publication date: March 21, 2024Inventors: Shirish VIJAYVARGIYA, Vasantha Kumar DHANASEKAR, Bidesh CHITNIS, Nakul Ranjan OGALE, Bharath Kumar CHANDRASEKHAR, Boris WEISSMAN, Robert James SPEAKER

Patent number: 4959807Abstract: A device for measuring the speed of a moving object has first and second impact detectors separated by a preselected known distance and disposed in the path of movement of the object. As the object strikes the first and second detectors, the detectors each produce a signal. The signals are separated by a time interval indicative of the distance between the detectors. The elapsed time between the signals is measured by a counter device, and the speed of the object is calculated by a programmable device.Type: GrantFiled: October 11, 1988Date of Patent: September 25, 1990Assignee: Atochem North America, Inc.Inventors: Mitchell L.
