Claim 11:
12. A method, comprising:
receiving a first lock/unlock signal at a powered door bolt assembly, the powered door bolt assembly comprising a motor, a bolt, and a lost rotational motion assembly including a first component connected with the bolt and a second component connected with the motor, the power door bolt assembly further comprising a coil spring extending between the first component and a relatively fixed structure of the powered door bolt assembly to axially urge the first component into a pocket of the second component in order to connect the second component to the first component, and a position sensor coupled to and moveable with the first component, the position sensor operably connected to control circuitry connected with the motor;
in response to the first lock/unlock signal, performing a first motor operation that comprises operating the motor to drive the second component in a first direction from a home position to a first rotated position, thereby rotating the first component from a first component first position to a first component second position, and thereby driving the bolt from a bolt first position to a bolt second position;
in response to the position sensor coupled to and moving with the first component providing an output indicating to the control circuitry that the first component has reached the first component second position, performing a second motor operation that comprises operating the motor to drive the second component in a second direction opposite the first direction from the first rotated position to the home position while the first component remains in the first component second position and the bolt remains in the bolt second position; and
in response to rotation of a manual actuator between a locking position and an unlocking position, decoupling the second component from the first component by depressing the manual actuator through the first component to compress the coil spring and axially displace the first component out of the pocket of the second component while rotating the first component between the first component first position and the first component second position, thereby driving the bolt between the bolt first position and the bolt second position so that the second component is maintained in the home position.
