Patents by Inventor Petr Petrov

Petr Petrov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11624846
    Abstract: A seismic monitoring system includes a plurality of seismic monitors and a processing device operatively coupled to the plurality of seismic monitors. The processing device receives recordings of waveforms of motion detected at the plurality of seismic detectors in a geographic area. The processing device applies the respective recordings to corresponding positions of the seismic detectors in a three-dimensional geological model that describes its elastic attributes and tests a plurality of moment tensors at a plurality of locations. Based on the testing, the processing device determines a globally convergent source location and moment tensor in the three-dimensional model based on the testing.
    Type: Grant
    Filed: September 17, 2018
    Date of Patent: April 11, 2023

  • Patent number: 10437280
    Abstract: Managing system clocks of virtual machines. A host system clock value of a host system clock of a host system is obtained, and a virtual machine system clock value of a system clock of a virtual machine managed by the host system is determined. The determining of the virtual machine system clock value includes using the host system clock value and a system clock adjustment value. The system clock of the virtual machine is adjusted using the virtual machine system clock value.
