Patent ID: 7800332

Claim:
A powered apparatus comprising: a driven component that is movable along a path between a first position and a second position; a drive motor that moves the driven component along the path; a motor speed detector that monitors an instantaneous speed of the drive motor at each position along the path; and an electronic control unit that operates the drive motor between the first position and the second position, the electronic control unit comprising: a load profile component comprising load profile data representing a plurality of motor loads associated with respective positions of the driven component along the path; a calculating component that determines a calculated final rest position of the driven component by adding a current position of the driven component along the path and an adjustment coefficient representing an additional distance of travel along the path based on the instantaneous speed of the drive motor and a respective motor load associated with the additional distance of travel; and a non-volatile memory component for storing the calculated final rest position of the driven component.
