An asset management system can be configured to receive at least a portion of a plurality of data and to determine a concentricity of at least one of the rotor or stator. The rotor or stator concentricity can be a vector including an amplitude and an angle and can characterizes a difference between a location of a predetermined center point and a location of a geometric center point of the rotor or stator, respectively. The system can also receive a concentricity vector selection including at least one of the rotor concentricity vector or the stator concentricity vector and can receive a selection of one of the correlated operating parameters. A plot format selection can be received and a graphical user interface (GUI) including a plot can be generated. The plot can include a portion of the selected concentricity vector as a function of the selected correlated operating parameter.

A tip gap monitoring system for a ducted aircraft having a proprotor system including a duct and a plurality of proprotor blades includes sensors coupled to the proprotor system. The sensors are configured to detect one or more parameters of the proprotor system to form a plurality of sensor measurements. The tip gap monitoring system also includes a flight control computer in data communication with the sensors. The flight control computer includes a tip gap measurement module configured to determine a tip gap distance between the duct and the proprotor blades based on the sensor measurements.

This application discloses a lithiation device for applying a lithium film on an electrode plate. The lithiation device includes: a rolling mechanism including a first roller and a second roller, the two rollers configured to roll the electrode plate and the lithium film to apply the lithium film on the electrode plate; an adjustment mechanism connected to the rolling mechanism and configured to adjust a gap and/or a rolling force between the first roller and the second roller; a first monitoring mechanism configured to monitor a length of the electrode plate after the electrode plate passes through the rolling mechanism; and a controller configured to control the adjustment mechanism based on a comparison result of the length monitored by the first monitoring mechanism and a target length so that the length of the electrode plate after the electrode plate passes through the rolling mechanism approximates to the target length.

A driving device includes a frame, a screw-nut system comprising a threaded rod and a first nut helicoidally connected to the threaded rod, the threaded rod being connected to the frame by a pivot connection that allows the threaded rod to rotate with respect to the frame about a longitudinal axis of the threaded rod, a first position sensor making it possible to detect a limit position of the first nut along the longitudinal axis, the first position sensor comprising a first part and a second part, the first position sensor being sensitive to a variation in a distance between the first part and the second part of the first position sensor along the axis, the first part being fixed to the first nut and the second part being connected to the threaded rod without passing via the pivot connection and in such a way that rotation of the threaded rod about the longitudinal axis leads to a variation in the distance between the first part and the second part of the first position sensor along the longitudinal axis.
