Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

Certain aspects of the technology disclosed herein include an apparatus and method for a extending a deadbolt. The electromechanical lock can include a deadbolt extending device disposed between a main housing and a deadbolt. The deadbolt extension device can be used to adapt the electromechanical lock to doors of various sizes. The deadbolt extension device can include another electrical connection and another attachment mechanism for the deadbolt. The another electrical connection can be configured to electrically connect the deadbolt with the main housing. The another attachment mechanism can be configured to attach the deadbolt a pre-defined distance apart from the main housing.

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.

Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.

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.

Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a seal device that includes a housing and a controller disposed inside the housing, with the controller including at least one sensor configured to measure motion data to detect motion of the seal device, and a communication module. The seal device further includes a seal connectable to the housing, with the seal including a shell and a conductive wire connectable to the controller. The controller is configured to cause the communication module to transmit at least one signal at least in response to one of, for example: a) determination, based on the motion data measured by the at least one sensor, of movement of the seal device, and/or b) detection of structural damage to the seal.

A door lock mechanism is disclosed that includes door lock and alarm features. The mechanism includes a controller and a sensor useful to detect motions that are representative of attempted access through a door to which the door lock mechanism is attached. The controller can set an alarm condition if a measured motion, such as a measured acceleration, meet and/or exceeds a threshold. If an appropriate access control credential is provided through a user device then the alarm condition may not be set by the controller. The door lock mechanism can be coupled to a remote station via a communications link if needed, such as a radio frequency link. The remote station can additionally be in communication with the door lock mechanism via a network. The remote station can be used to send and receive messages regarding door lock mechanism status, configuration, etc.

An electronic door lock including a magnetometer, an accelerometer, and a processor. The processor is configured to determine a status of a door with respect to a door frame using data provided by the accelerometer and magnetometer which collectively generate acceleration data, velocity data and positional data of the door. The processor provides data to a user interface or an alert device indicating one or more of: door open angle, prep-less door position, an acceleration alert, a door position alert, door sag, door frame rub, and triangulation of an intruder.

An alarm for a door is operable to generate an alarm signal when a rotary grip member of the door is rotated to a particular position, such as an unlocked position. The alarm comprises a housing having a strap retainer configured to receive and retain a strap to hold the housing to the rotary grip member. The alarm comprises a tilt switch for switching when the housing is tilted. Control circuitry is interconnected to the tilt switch and to an annunciator and is operable to activate the annunciator dependent on a state of the tilt switch.
