  • Patent number: 10564057
    Abstract: Various sensor assemblies are described herein that can measure axial and lateral forces and/or axial and lateral torques acting on an instrument independent of steady state temperature variations. In one embodiment, the sensor assembly has a sensor body for coupling to the instrument such that a shaft and tip of the instrument extend from opposing ends of the sensor body. The sensor body has first and second strain sensing regions. The sensor assembly further includes first and second strain sensors coupled to and configured to measure axial strain of the first and second regions, respectively. During use, when the sensor body is coupled to the instrument, each of the first and second regions experience an opposite one of a tensile axial strain and a compressive axial strain in response to an axial force or an axial torque acting on the tip of the instrument.

  • Patent number: 10557963
    Abstract: Techniques and apparatus are provided for downhole sensing using optical couplers in a downhole splitter assembly to split interrogating light signals into multiple optical sensing branches. Each optical branch may then be coupled to an optical sensor (e.g., a pass-through or an optical single-ended transducer (OSET)) or to another optical coupler for additional branching. The sensors may be pressure/temperature (P/T) type transducers. Some systems may exclusively use OSETs as the optical sensors. In this manner, if one of the OSETs is damaged, it does not affect light traveling to any of the other sensors, and sensing information from remaining sensors is still returned.
