Antriebsschaltung für bewegliche Röntgengeräte.

摘要

A control system for providing power to independently driven wheels (l2, l4) of a power driven cart (l0) for transporting medical diagnostic equipment. A manually engageable handle (l6) is mounted to the cart in a position allowing a person to exert a manual force on the handle in a direction in which it is desired for the cart to move. Force sensors (38, 40) are coupled to the handle to sense the manual force applied to it in a plane parallel to the plane on which the cart is to be moved. The force sensors (38, 40) provide signals representative of the magnitude and direction of the manual force applied to the handle in forward, reverse and turning directions. Electronic circuits (26, 28) are coupled to the force sensors for providing control signals to motors driving the wheels of the cart for independently controlling direction and velocity of movement of the cart.
