Lock devices, systems, and methods including an internal mechanism to permit backdriven operation and lost motion operation. In one form, the lock includes an assembly of parts with locating features that assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components that can also be displaceable, in some embodiments, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A lever arm is movable between disengaged and engaged positions and moves the lock bolt between the locked and unlocked positions. A rotary element is engageable with the lever arm in the engageable position. The rotation of the rotary element when the rotary element is engaged with the lever arm moves the lock bolt between the locked and unlocked positions. A pin normally blocks the lever arm from moving from the disengaged position to the engageable position. A rotatable output gear moves a rack gear and the pin to unblock the lever arm and thereby allowing the lever arm to engage with the rotary element to allow a user to rotate the rotary element to move the lock bolt between the locked and unlocked positions.

An electronic lock with a lock assembly that includes a bolt movable between an extended position and a retracted position. The electronic lock includes a motor configured to drive the bolt between the extended position and the retracted position. A controller is provided that is configured to control actuation of the motor to selectively move the bolt between the extended position and the retracted position. The electronic lock includes a user interface configured to output information about the electronic lock. A misalignment scoring means is provided for detecting interference to movement of the bolt between the extended position and the retracted position and determining a lock misalignment score based on the detected interference. The user interface identifies the lock misalignment score.

A power control system for use with an electric lock mechanism including an actuator having a coil with a particular coil impedance. The power control system comprises a power supply configured to provide an output voltage having a drive current to the actuator, a credential device powered by the power supply and configured to signal the power supply to provide the output voltage upon receiving an authorized access code, an actuator driver including a multiple-gain current-sensing circuit, and a microcontroller configured to monitor and control the power supply, credential device, actuator driver, and actuator, and determine the impedance of the coil. The microcontroller is populated by a look-up table having performance data for a plurality of coils such that the microcontroller selects a duty ratio to establish the optimum magnitude of drive current to the coil based only on the determined impedance of the coil.

Lock devices, systems, and methods that can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock includes an assembly of parts that includes parts having locating features that that can assist in those parts being assembled with other parts of the assembly in a single, relative orientation. Further, lost motion may be utilized to accommodate manual displacement of one or more components of the can also be displaceable, in at least certain situations, via operation of a motor. The lock can also include an internal power source capable of driving electronics used to determine handedness of a door.

A power control system for use with an electric lock mechanism having an actuator comprises a power supply to output an output voltage to the actuator. A credential device signals the power supply to output the voltage upon receiving an authorized code. A microcontroller controls the power supply, the credential device, and the actuator and may operate in an Access Mode or a Dog Mode. When in Access Mode, the actuator is unpowered and the credential device is powered until an authorized code is received and the power supply powers the actuator. The Dog Mode has an awake mode where the actuator is powered and the credential device is unpowered after the actuator remains in the powered state for a length of time. A sleep mode has the actuator unpowered and the credential device powered until an authorized code is received and the power supply powers the actuator.

A lock state monitoring apparatus, a method, a lock driving apparatus and a lock assembly. The lock state monitoring apparatus includes: a rheostat and a first load, where a movable contact end of the rheostat is connected with a first end of the first load, and a first fixed end of the rheostat and a second end of the first load are configured to bear a first voltage; the movable contact end of the rheostat is configured to be connected with an output axis of a drive motor in the lock; the first fixed end and the movable contact end of the rheostat, or two ends of the first load, are configured to be connected with a main control board in the lock to output a first voltage signal to the main control board, so that the main control board determines a lock state according to the first voltage signal.

A wirelessly controlled door stop is disclosed. In particular, the door stop can include a body portion and a rotatable stop along with a microprocessor and a wireless transceiver. When proper authorization is received the microprocessor activates the rotatable stop, which then rotates from within the body portion to a deployed position that will prevent access to a doorway in which the door stop has been installed. Additionally, the access to the door stop can be logged by a cloud system, which can be accessed by the door stop by the Internet.

An electronic seal (e-seal) device and related techniques are disclosed. In accordance with some embodiments, the disclosed e-seal device may be configured to e-seal a given host platform. The disclosed e-seal device may include a radio frequency (RF) wireless transmitter configured, in accordance with some embodiments, to transmit a signal including data that may be compared against data from a server database in determining whether the e-seal has been compromised. When received by an authorized recipient within range, information from the signal may be delivered through the internet to the server database, which may be cloud-based in some instances, allowing for inter-networking of the system components and other elements as part of the internet of things (IOT). Reader and other computing devices may access the information stored at the server database to monitor and track the e-sealed platform, as well as control overall system operation.
