AI Technical Summary

Benefits of technology

This patented technology allows for better stabilization and reduction of unwanted movements when used with certain types of machines such as electric motors or generators. It achieves this through combining two different techniques - one uses an active controller called the rotating machine (RM) while another uses permanent magnets on either side of the motor' s axis. By adjusting both these methods based upon their respective functions they can improve the overall functioning of the device without adding extra components like relays or sensors.

Problems solved by technology

This patents describes various technical problem addressed in these inventions relating to improving the safety and durability of electric vehicles' batteries due to the lack of regulated cleanliness (GWC). Specifically, existing battery technologies like lithium ion batteries suffer from environmental concerns related to fluctuations in voltage levels during recharge cycles. To address this issue, researchers developed passive electronic insulation devices called inductively controlled pendants (IPE), which act as physical isolators without causing damage when they come close together. However, IPEs still face challenges including maintaining constant velocity and stabilized rotation under severe conditions while reducing noise emissions.
