  • Optimized placement of vibration damper tools through mode-shape tuning
    Patent number: 11692404
    Abstract: Systems and methods for damping torsional oscillations of downhole systems are described. The systems include a downhole drilling system disposed at an end of the downhole system in operative connection with a drill bit. A damping system is installed on the downhole drilling system, the damping system having at least one damper element configured to dampen at least one HFTO mode. At least one mode-shape tuning element is arranged on the drilling system. The at least one mode-shape tuning element is configured and positioned on the drilling system to modify at least one of a shape of the HFTO mode, a frequency of the HFTO mode, an excitability of the HFTO mode, and a damping efficiency of the at least one damper element.

  • Notification engine
    Patent number: 9497042
    Abstract: A method and apparatus are provided. The method is carried out by a notification engine, for delivering to a user equipment a group of incoming notifications from at least one application running on the user equipment. The application running on the user equipment is registered on the notification engine. The method includes: defining at least one criterion for delivering notifications, buffering the incoming notifications, and delivering according to the criterion a group of previously buffered notifications.
