  • Patent number: 9279666
    Abstract: A system is provided for monitoring strain in a substrate using a strain sensor element within a fiber optic sensing cable. Accurate and rapid measurement of strain of remote substrates presents major technical challenges and is the focus of much of the description presented. However, systems, methods and devices provided by the present invention are not only capable of reliably measuring strain in real time, but are also capable of measuring other characteristics of a substrate such as its temperature, pressure and its acoustic characteristics. The system is configured such that a strain sensor element within a strain sensing zone detects substantially the true strain characteristics of the substrate. And while other sensing elements within the same fiber optic sensing cable may not be configured to detect substrate strain at all, these sensing elements may reliably measure the temperature and pressure at the surface of the substrate adjacent to the strain sensing zone.

  • Patent number: 8839926
    Abstract: An actuator decoupler for selectively coupling and decoupling a driving part and a driven part of an actuation system is disclosed. The driving part can be coupled to the actuator decoupler, and the actuator decoupler can be coupled to the driven part via at least one coupling pin. In a selectively coupled state, the driven part can be at least one of rotationally and longitudinally fixed to the actuator decoupler and, thereby, the driving part. The actuator decoupler can be decoupled from the driven part through the use of a preloaded energy mechanism configured to disengage the at least one coupling pin from the driven part. Thereby, the actuator may be responsive to a jam in the actuation system to selectively decouple the driven part from the actuator decoupler and the driving part so that the driven part has freedom to translate at least one of rotationally and longitudinally.
