Abstract: A motion control system that can detect a change in a an operating characteristic and send a stabilizing command to an actuator system based on the change is described. A motion control component in the system includes a first component with an electropermanent magnet having a coil, differing first and second permanent magnet materials, and differing first and second states. The motion control component includes a second component configured to magnetically interact with the first component to define a damping characteristic that affects motion between the first component and the second component and a controller configured to supply a current pulse to the electropermanent magnet to switch the electropermanent magnet between the first and second states. The electropermanent magnet retains the respective first or second state after cessation of the current pulse.

Abstract: A system that includes a radar sensor configured to transmit radar waves receive a first group of reflected radar waves and a second group of reflected radar waves. A restraint includes a material that causes the transmitted radar waves to reflect off the restraint to generate the first group of reflected radar waves, and the second group of radar waves is reflected off objects other than the restraint. A controller is configured to determine a shape of the restraint based on the first group of reflected radar waves.
