An intelligent door lock system is coupled to a door at a dwelling. A door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. Near field communication (NFC) is used to identify a lock device via an RF protocol. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

A drawer assembly is described that includes one or more mini-drawer assemblies. A mini-drawer assembly comprises a sliding tab along a rear-to-front axis, a release mechanism coupled to the sliding tab, and a body having a body bottom coupled from the body bottom to the sliding tab. The body may slide over the sliding tab. The mini-drawer assembly may include a plurality of compartments in the body and a plurality of lids that are hingedly coupled to the compartments. Each lid may have a respective fastening element. A plurality of latches may couple to the body such that each latch is coupled to a corresponding compartment. The latch may hold the respective fastening element of the lid. When the body is pulled out along the rear-to-front axis, the release mechanism may engage with the latch to release the respective fastening element and to unlatch the lid of the compartment.

Certain aspects of the technology disclosed herein include an apparatus and method for electrically and mechanically connecting a deadbolt to a main housing of a lock. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door while receiving electrical energy from an energy storage device disposed in the deadbolt. The energy storage device disposed in the deadbolt can be proximate to one or more electrical contacts electrically connected to one or more components in the main housing via conductive components of a bolt carriage. The bolt carriage includes a groove attachable to a male detent connector attached to the deadbolt. The groove in the bolt carriage provides a mechanical connection to the deadbolt and also aligns pogo pins with electrical components of the bolt carriage to enable electrical transmission from the deadbolt to the main housing.

Determining a position of a deadbolt used to lock and unlock a door is disclosed. An electromechanical lock can include a deadbolt that can retract or extend along a linear path as the door is to be locked and unlocked. A sensor such as an accelerometer can rotate along a non-linear path as the deadbolt moves along a linear path. The accelerometer can determine a gravity vector that can be indicative of a position of the accelerometer along the non-linear path. A controller can then determine a position of the deadbolt based on the gravity vector.

An electronic lock apparatus includes an input panel and a control box. The control box includes a box body, a circuit board, a connection cable, a back plate, and a sensing assembly. The circuit board is disposed in the box body, and includes an electronic lock switch control module. The connection cable is disposed on the circuit board, electrically connected to the electronic lock switch control module. The sensing assembly is disposed on the circuit board, faces a back opening of the box body, and is configured to sense whether the back plate covers the back opening. The electronic lock apparatus can provide an unlocking manner of wireless, a biological feature, password entry or a combination thereof as a basis of controlling an electronic lock, and include a safety protection design, to improve safety of near-end and/or remote access control management.

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.

An exterior, residential door system comprises an outer door frame adapted to be mounted within an exterior opening of a residence, an exterior residential door pivotally attached to the outer door frame, at least one electric device installed on the door, a main controller mounted to the door, an electric power supply unit operably associated with the door, and a wire harness integrated into the door for transmitting electric power and electrical signals between the electric device, the controller and the source of electric power. The main controller is configured to cooperate with the wire harness to supply power to the at least one electric device and to supply operating signals to the at least one electric device for operating the at least one electric device and to receive operational signals from the at least one electric device responsive to the operating signals.

An intelligent door lock system is coupled to a door at a dwelling. A door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A plurality of cameras that communicate with each other and with the lock device.

An exemplary lockset is configured for installation in a standard door preparation, and includes an exterior assembly, an interior assembly, and a center assembly connecting the exterior and interior assemblies. The exterior assembly includes an exterior escutcheon which houses a credential reader assembly including a multi-tech credential reader. The interior assembly includes an interior escutcheon which houses a control system. The center assembly includes a chassis, an outer surface of which may define a channel. The credential reader assembly is in communication with the control assembly via a wire harness, a portion of which may pass through the channel.
