    摘要: A non-contact type potentiometer with high resolution of rotation amount detection applicable to endlessly multiple rotations. The potentiometer has an endlessly rotatable first shaft, a first detection unit that magnetically detects a rotation angle of the first shaft in a non-contact manner, an endlessly rotatable second shaft, a second detection unit that magnetically detects a rotation angle of the second shaft in a non-contact manner, a transmission unit that decreases the speed of the rotation of the first shaft and transmits the rotation to the second shaft, and an output unit that outputs an electric signal proportional to a rotation amount of the first shaft based on detection signals from the first detection unit and the second detection unit.

    摘要: Noise control systems and methods for brakes and clutches are disclosed, in which voltage profiles comprise at least one or two step profiles and at least one ramp profile. The voltage profiles are selectively applied to at least one of a stationary member or rotary member of the brake or clutch in order to decrease noise during operation thereof. Such systems and methods can be adapted for use in medical imaging equipment, particularly to decrease the noise of brakes and clutches commonly associated therewith.

    摘要: A method and system for reducing or eliminating uncontrolled motion in a motion control system is disclosed herein. The method includes defining at least one closed motion control loop. The motion control loop comprises a plurality of feedback control loops. The method further includes detecting a faulty feedback control loop from among the plurality of feedback control loops based on a faulty feedback signal. Once the faulty feedback signal is detected, the faulty feedback signal in the faulty feedback control loop is swapped to an operative feedback signal while the motion control loop is active. In an embodiment the motion control loop includes a velocity feedback control loop and a position feedback control loop.
