  • Sensing system for detecting rubs events or wear of an abradable coating in turbo machinery
    Patent number: 12553357
    Abstract: A sensing system and method for detecting wear of an abradable layer on a stationary engine casing is provided. The system is capable of measuring the abradable thickness of the abradable layer by embedding abradable sensor in the abradable layer and measuring the changing electrical properties as the abradable sensor wears.

  • ACTIVE VIBRATION CONTROL SYSTEM
    Publication number: 20250226782
    Abstract: This disclosure provides a circular force generator system (100) which incorporates a failsafe component. The failsafe component provides a brake system on the circular force generator such that the rotor of the circular force generator is rapidly brought to a stop in response to a predetermined sensor output or a manual override of the circular force generator system.
