The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

This invention presents a unique propulsion and maneuver-control system for crafts and devices. This invention develops its desired thrust force vectors from the vectors sum of centrifugal force vectors of rotating masses and their controlled gyroscopic force vectors. Also shown are applications of this propulsion and maneuver-control system for future VTOL-Hovering-Flying crafts, Scooters, Surfboards, marine/submarine-crafts, earth, moon, mars satellites disks and space-crafts. This invention has great potentials of creating new businesses in aerospace markets, all planets' weather modification business, bring people of the world closer together and perform critical tasks of modify trajectories to prevent run-away asteroids from hitting the earth.

A method for operating a washing machine appliance includes flowing a volume of liquid into a tub, and agitating articles within the tub for a first period and using a first agitation profile, the tub containing the volume of liquid. The method further includes measuring movement of the tub during agitation of the articles within the tub, wherein the step of measuring movement occurs after agitating articles within the tub for the first period and for an intermediate measurement period and using an intermediate agitation profile, and wherein the intermediate agitation profile is different from the first agitation profile. The method further includes agitating articles within the tub for a second period when the final measured movement is greater than an out-of-balance movement threshold. The method further includes draining liquid from the tub when the final measured movement is less than the out-of-balance movement threshold.

A method is for correcting an imbalance in a computed tomography system, in which a supporting structure includes a radiation source is fitted on a fixed mounting frame. The supporting structure rotates together with the radiation source about a measurement space, in which is fixed in place a measurement object having a known attenuation response for the radiation emitted by the radiation source. The method includes detecting first measurement data of the radiation while the supporting structure rotates about the measurement object, determining an imbalance arising during the rotation of the supporting structure on the basis of the acquired first measurement data of the radiation, and determining a position and a weight of at least one counterweight on the supporting structure in order to reduce the determined imbalance, or determining correction data, which is used to correct the imbalance in software.
