Abstract: The invention concerns a method for monitoring the operating state of a system for positioning variable-geometry members (18) of a turbomachine (10), the members (18) being configured to travel over an operating area comprising a first position P1 and a second position P2, the method comprising the steps of: -(E23) determining a first pivoting speed V1 from the first position P1 to the second position P2; -(E25) determining a second pivoting speed from the second position P2 to the first position P1; and -(E26) determining an anomaly in the operation of the system for positioning the members (18) if the first speed V1 is lower than a first determined speed threshold and/or if the second speed V2 is lower than a second determined speed threshold.

Abstract: A crankset for a pedal-driven vehicle has a frame with a bottom bracket shell. The crankset includes a crank arm rotatably mounted to the bottom bracket shell of the frame; a spindle operatively connected to the crank arm at an end spaced-apart from the bottom bracket shell and rotatable about a spindle rotation axis. A stationary member fixedly mounts to the bottom bracket shell. A rotatable member operatively engages the spindle and is configured to engage the spindle in rotation. A connecting assembly operatively engages the stationary member and the rotatable member. The connecting assembly is configured to engage the rotatable member in rotation upon rotation of the crank arm about the bottom bracket shell. A pedal angular control assembly operatively connects to the spindle and is configured to control an angle of a pedal according to an angular position of the crank arm during rotation.
