Abstract: According to some exemplary embodiments described herein, a door lock may include a driveshaft operatively couplable to a bolt configured to move between an extended position and a retracted position to selective secure an associated door. The door lock may also include a transmission coupled to the driveshaft, where the driveshaft includes at least one gear configured to rotate with the driveshaft. The door lock may also include a magnetic encoder coupled to the transmission and configured to measure a position of the at least one gear. The magnetic encoder may include a diametrically polarized magnet coupled to the at least one gear.

Abstract: Door lock systems and related methods of use are provided. A motor of a door lock system may be placed against a surface of a housing and a bracket may be placed between the motor and a wall of the housing. The motor may be secured in the housing by moving the bracket against the wall of the housing to retain the bracket and apply a force to the motor. A door lock system may include a mounting bracket configured to receive a housing of the door lock system and secure the door housing to an associated door.

Abstract: A rotary knob for operating an electronically actuable deadbolt is described herein. According to some embodiments, the rotary knob includes a chassis, an outer wall rotatably coupled to the chassis about a central axis of the knob, a cantilevered beam attached to an inner surface of the outer wall and extending towards the central axis of the knob such that the beam is configured to rotate with the outer wall about the central axis, a circuit board coupled to the chassis, the circuit board including signal traces, and an electrical contact extending from the cantilevered beam in a direction toward the signal traces and electrically connectable with the signal traces. A controller of the rotary knob is configured to determine a position of the deadbolt based on at least the state of the electrical connection between the electrical contact and the signal traces.

Abstract: In some embodiments, a method of determining whether a door is ajar may include determining an orientation of a door lock of the door, and, based on the orientation of the door lock, analyzing at least one signal from at least one of two or more proximity sensors of the door lock. The method may further include determining whether the door is ajar based at least in part on a result of the analyzing of the at least one signal. In some embodiments, a method of determining a status of a door may include receiving a first signal from a first magnetometer disposed within a door lock of the door, receiving a second signal from a second magnetometer disposed within the door lock of the door, and detecting, based on a result of an evaluation of both the first signal and the second signal, a possible attack on the door.

Abstract: In some embodiments, a clutch for a door lock may include an output gear including a plurality of inner detents and a lag plate rotatable relative to the output gear and configured to generate friction when the lag plate rotates. The clutch may also include an input cam configured to be coupled to an output shaft of an actuator, where the input cam is configured to switch between an engaged state and a disengaged state. The clutch may also include a ball bearing configured to engage one of the plurality of inner detents when the input cam is in the engaged state. The ball bearing may also be configured to disengage from the plurality of inner detents under frictional force generated by the lag plate when the input cam is in the disengaged state and the output gear is rotated by an external force.
