Abstract
An examination table includes a support surface movable with respect to a base. The support surface includes a seat portion and a backrest portion. A first motor drives the support surface with respect to the base, and a second motor drives the backrest portion pivotally with respect to the seat portion. A control system includes a control panel and first and second Hall-effect sensors for detecting rotations of the respective first and second motors to determine the current positions of the support surface and the backrest portion. The control system executes a movement algorithm for moving the support surface and the backrest portion to a desired position from the current position. The control system also executes a calibration algorithm for calibrating position tracking of the support surface and the backrest portion.
