摘要： A system and method for monitoring bend radius and torque force exerted on a drill string. A sensor system is supported within a pipe section of the drill string and has a light source supported within the pipe section to emit a light beam within the pipe section. An optical sensing device is supported within the pipe section and spaced apart from the light source. The optical sensing device transmits a detection signal indicative of the position of the light beam on a surface of the optical sensing device to a processor that determines the bend radius and torque force exerted on the pipe section.

摘要： An electric power steering system includes a motor, rotation angle sensors, a determination unit, and a control unit. The determination unit determines whether each rotation angle sensor has a failure by one of determination methods depending on whether a situation is a first situation where one of the rotation angle sensors has a failure or a second situation where the rotation angle sensors have no failures. In the first situation, the control unit continues to control driving of the motor based on a rotation angle of the motor detected by a remaining rotation angle sensor having no failure. Only when determining, in the first situation, whether there is a failure in the remaining rotation angle sensor, the determination unit determines whether there is a failure based on whether a steering torque exhibits a specific behavior assumed to be detected when there is a failure in the remaining rotation angle sensor.

摘要： A system for measuring torque to which a body is subjected by twisting the body about an axis defined thereby. The system includes one or more fiber Bragg gratings secured to the body. Each of the fiber Bragg gratings is positioned so that the fiber Bragg grating is located at least partially non-parallel with the axis of the body. The system also includes one or more light sources for providing light transmittable to the fiber Bragg grating(s). The light transmitted to the fiber Bragg grating(s) is filtered thereby to provide a modified light having one or more characteristic spectra. The sys tem also includes an analyzer for analyzing said at least one characteristic spectrum to determine the torque to which the body is subjected.

摘要： A device for measuring torque applied through a rotating member. A first torsion reference member is fixedly coupled to the rotating member at a first axial position and a second torsion reference member is fixedly coupled to the rotating member at a second axial position. A first detector detects the passage of the first torsion reference member past the first detector upon each full rotation of the rotating member and to generate a first signal upon each passage of the first torsion reference member. A second detector detects the passage of the second torsion reference member past the second detector upon each full rotation of the rotating member and to generate a second signal upon each passage of the second torsion reference member. A controller calculates a phase difference between the first signal and the second signal relative during rotation of the rotating member under a torsional load.
