Abstract: Systems and methods here may be used to improve the efficiency of electric motors by increasing the number of windings of coils included in electric motors.

Abstract: A shield assembly for providing a barrier adjacent to a patient disposed on a patient support apparatus. The shield assembly comprises a support frame defining a closed periphery and including a resilient element extending along the closed periphery to resiliently urge the support frame toward a bias frame shape. A barrier panel is coupled to the support frame and spans the closed periphery. The shield assembly may further include a base operatively attached to the support frame to selectively place the support frame in a contour frame shape. Tension in the resilient element effected by the base holding the support frame in the contour frame shape places the barrier panel in a curved configuration to define a patient accommodation space shaped to receive the patient adjacent to the base and to the barrier panel.
