Abstract
Lock devices, systems, and methods including an internal mechanism to permit backdriven operation and lost motion operation. In one form, the lock includes an assembly of parts with locating features that assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components that can also be displaceable, in some embodiments, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

-20. (canceled)
A non-transitory computer readable medium configured to store executable instructions comprising:
- lock actuation instructions executable to control an actuator to apply force to a locking mechanism of a door lock to move the locking mechanism in a locking direction and an unlocking direction;
- and
- position sensing instructions executable to evaluate a state of an encoder including a plurality of circuits, the state of said plurality of circuits varying based on a position of the locking mechanism;
- wherein a first set of states of the plurality of circuits of the encoder designates a first position of the locking mechanism corresponding to a left handed lock configuration of the door lock;
- and
- wherein a second set of states of the plurality of circuits of the encoder designates a second position of the locking mechanism corresponding to a right handed lock configuration of the door lock.
A door lock, comprising:
- a locking mechanism configured to move in a locking direction and an unlocking direction via an actuator;
- and
- an encoder including a plurality of circuits, states of said plurality of circuits varying based on a position of the locking mechanism;
- wherein a first set of states of the plurality of circuits of the encoder designates a first position of the locking mechanism corresponding to a left handed lock configuration of the door lock;
- and
- wherein a second set of states of the plurality of circuits of the encoder designates a second position of the locking mechanism corresponding to a right handed lock configuration of the door lock.
The door lock of claim 39, wherein the controller is operable to evaluate whether the locking mechanism was last actuated automatically or manually based upon input from at least one of the first position sensor and the second position sensor.
