Patent number: 10801901Abstract: Systems, methods, and devices for positioning, orienting, and/or aligning a stress sensor assembly are provided. In some embodiments, a sensor assembly can be received within a retaining element of a sensor mounting assembly. The sensor mounting assembly can include the retaining element, an adjustment mechanism, a first member, a second member, and a third member. The adjustment mechanism can allow the sensor assembly to be displaced linearly in a proximal and/or distal direction. The first and second members can be pivotally coupled to enable the sensor assembly to be rotated about a first axis, and the second and third members can be pivotally coupled to allow the sensor assembly to be rotated about a second axis.Type: GrantFiled: June 27, 2019Date of Patent: October 13, 2020Assignee: General Electric CompanyInventors: Martin Bucher, David Folkner, Dan Tho Lu, Lysle Turnbeaugh, Brian F.

Patent number: 10684181Abstract: A gap compensated torque sensing system and methods for using the same are provided. The system can include a magnetostrictive torque sensor and at least one proximity sensor in communication with a controller. The proximity sensor can be substantially rigidly coupled to a sensor head of the torque sensor, either contained within the sensor head or mounted proximate to the sensor head using a bracket or other coupling mechanism. The torque sensor can sense magnetic flux passing through the target and the proximity sensor can measure a gap between itself and the target. The controller can estimate torque applied to the target from magnetic flux sensed by the torque sensor. The estimated torque can be modified by the gap measurement to compensate for changes in magnetic properties of the target due to variations in the gap. In this manner, the accuracy of the torque measurements can be increased.Type: GrantFiled: January 8, 2018Date of Patent: June 16, 2020Assignee: Bently Nevada, LLCInventors: Dan Tho Lu, Lam Arthur Campbell, Brian F.

Patent number: 10677676Abstract: Systems, methods, and devices for positioning, orienting, and/or aligning a stress sensor assembly are provided. Raw stress signals, which can correspond to stress in the target, can be generated by detecting a magnetic flux that travels through the target. The raw stress signals can be sensitive to an alignment of the sensor relative to the target. In order to minimize measurement error, the stress sensor can be properly aligned relative to the target prior to taking a stress measurement. Sensor alignment can involve adjusting a yaw, pitch, and/or roll of the sensor, measuring the raw stress signals, attenuating the detected magnetic flux, and measuring the raw stress signals again. When the stress sensor is properly aligned, a change in a size of a gap between the sensor and a surface of a target can result in approximately equal changes in the raw stress signal.Type: GrantFiled: September 6, 2017Date of Patent: June 9, 2020Assignee: Bently Nevada, LLCInventors: David Folkner, Dan Tho Lu, Lysle Turnbeaugh, Brian F. Howard, Trevor Cowan, Brian Bowlds, David O'Connor

Publication number: 20200166418Abstract: A stress sensing system for measuring stress in a conductive target material includes at least one sensor positioned proximate to the conductive target material. The sensor is configured to measure stress in the conductive target material and to transmit a signal indicative of the measured stress to a controller. The controller is coupled in communication with the sensor. The controller is configured to receive the signal from the sensor, determine a runout portion of the signal corresponding to the runout of the conductive target material, determine a runout pattern waveform from the runout portion, and subtract the runout pattern waveform from the signal.Type: ApplicationFiled: November 8, 2019Publication date: May 28, 2020Applicant: General Electric CompanyInventors: Brian F.
