  • Method and apparatus for object collision detection utilizing a PID controller in a motorized, mobile C-arm
    Patent number: 7029175
    Abstract: Certain embodiments of the present invention relate to a collision detection system. The collision detection system includes a position indicator for determining an actual position of a component connected to the collision detection system. The system also includes an error calculator for determining a position error between the actual position and a selected position. The system further includes a comparator for comparing the position error to a position error limit. The comparator generates a halt signal based on the position error and position error limit. The system also includes a motion controller for controlling motion of the component. The motion controller stops motion of the component based on the halt signal. The comparator generates a halt signal when the position error is equal to or greater than the position error limit.
