Abstract: A garage door opener system includes a garage door opener having one or more sensors configured to monitor the status of a garage door as it moves between first and second positions. The garage door opener system may detect one or more anomalies in a profile generated from information from the one or more sensors and alert a user to the presence of those anomalies. The garage door opener system may allow a user to find and contact a service provider to address the one or more anomalies.

Abstract: An air channel is utilized to ventilate a door lock for the purpose of reducing the condensation of warm, humid, air within the lock. The air channel is configured to be located between a surface mounted door lock and the door panel and vent the space between the interior and exterior locks, including the door bore. In some embodiments, the air channel is formed into the mounting bracket for the interior door lock. The air channel may be implemented to reduce condensation without requiring seals or gaskets between the interior and exterior locks.

Abstract: A deadbolt lock assembly is disclosed. The deadbolt lock assembly includes an exterior lock mechanism and an interior lock mechanism mechanically connected through a bored hole in a door. The exterior portion of the lock assembly includes a reinforced chassis with a reinforced lock cylinder bore and an anti-rotation arm to enhance the lock's resistance to attack. The interior portion includes a thumbturn that is physically connected to the gearbox frame for robustness and includes stabilizing detents to improve the user feel. The gearbox frame and mounting bracket are connected with a single screw and spring-loaded latch for ease of assembly.

Abstract: A clutch for a door lock may comprise an output shaft configured to operate the door lock, and a thumb turn shaft coupled to the output shaft comprising an inclined projection. The clutch may also comprise an input gear configured to be coupled to an actuator output, and a coupler coupled to the input gear such that the coupler and input gear rotate together. The coupler may be configured to translate between an engaged position and a disengaged position, where the inclined projection of the thumb turn shaft is configured to move the coupler from the disengaged position to the engaged position when the thumb turn shaft rotates relative to the coupler. In the disengaged position the coupler may be decoupled from the output shaft.

Abstract: Systems and methods for detecting whether a door lock bolt is engaged with a door jamb recess in a locked position is provided. Certain of the systems and methods described herein detect engagement between a door lock bolt and door jamb recess using a motor current signature. Certain of the systems and methods described herein detect engagement between a door lock bolt and door jamb recess using a bolt vibration signature.

Abstract: Embodiments described herein relate to a motorized door lock detection system. Some embodiments of the device include a sensor gear that meshes directly with the gear system of the motorized door lock. As the sensor gear rotates, it drives the rotating contact of a potentiometer, varying the voltage in a reference circuit that corresponds directly with an angular position of the thumb-drive used to drive the deadbolt. In some embodiments, a conducting member that rotates with the output shaft of the deadbolt contacts a plurality of electrical contacts positioned such that they are contacted when the deadbolt is in a position range that requires more precise position monitoring. When the conducting member is in contact with a deadbolt, power is supplied such the output from the potentiometer can be determined. In this way, power to the potentiometer and/or controller driving the potentiometer can be limited.

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: Embodiments disclosed herein relate to secure storage boxes having a lock post bracket attached to a lid of the secure storage box and a lock body bracket attached to a body portion of the secure storage box. The lost post bracket may be constructed to retain a lock post, and the lock body bracket may be constructed to retain a lock body. The lock body may include an opening configured to selectively retain the lock post when the lid of the secure storage box is closed. Thus, the lock body may prevent the lid of the secure storage box from opening by retaining the lock post. Moreover, the lock post bracket and the lock body bracket may include features for confirming the alignment of the lock post to the opening in the lock body. For example, the lock post bracket may include two or more hollow cylinders configured to register with two or more complementary pins disposed on the lock body bracket.

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.

Abstract: A door handle assembly that allows for easy removal and switching of handles. Such an arrangement may provide the flexibility to change handle orientation and interchange handles based on a user's circumstances or preferences such as when a door handle is configured as a lever having a curved shape. Further, the door handle may be configured as a door lock having a keypad access control. The face of the keypad accessible from outside the door may include auxiliary battery terminals to provide the user with easy accessibility for providing temporary power to the door lock with an auxiliary battery should the installed batteries housed within the door lock fail to provide sufficient power.

Abstract: A progressive deadlatching arrangement for a deadbolt lock prevents an external force applied on the deadbolt from retracting the deadbolt or otherwise compromising a secured door. The progressive deadlatching arrangement prevents external forces from retracting the deadbolt while still allowing an authorized user to operate the deadbolt.
