Abstract: 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.

Abstract: A system, method and apparatus for generating random numbers. An electronic device operates an electric motor to drive a mechanical device. The electronic device includes a processing device structured to take one or more current measurements of the electric motor. The processing device is also structured to generate a seed and/or a random number based on at least one of the current measurements of the electric motor.

Abstract: A lock device is configured to receive a credential from a mobile device. The lock device is configured to monitor the distance between the mobile device and the lock device. The lock device is configured to detect an intent action by a user of the mobile device and unlock the lock device if the mobile device is within a predetermined distance from the lock device and the intent action is an approved intent action.

Abstract: A mobile device is configured to wirelessly authenticate with a reader device. The mobile device may receive an acoustic signal from a user, and a command may be determined based on the acoustic signal. The mobile device may transmit the command to the reader device if the mobile device and the reader device are authenticated. The reader device may receive the command, and may analyze the command to determine an action to be performed. The reader device may then perform the action if the mobile device is authorized to request the command to be performed.

Abstract: A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.

Abstract: A residential key may be programmed by a computer with access rights information. A lock device may receive the access rights information from the residential key. The lock device may store and utilize the access rights information if the lock determines that the residential key is authorized to update the lock device.

Abstract: Disclosed are various embodiments of lock devices, systems, and methods. A locking system includes a locking mechanism with a controller configured to provide an actuation signal to an electronic actuator to extend or retract a locking mechanism and to adjust an allowable peak current for operating the electronic actuator to throw the deadbolt based on whether the allowable peak current is sufficient for the locking mechanism to achieve its locked or unlocked positions. The allowable peak current can be adjusted over time between a minimum and maximum peak current, thus optimizing the actual current draw from the electronic actuator required to throw the locking mechanism and minimizing power consumption.

Abstract: An exit device that includes a locking mechanism for locking and unlocking a door, the locking mechanism having a latch bolt, and a link connected to the latch bolt, movement of the link between locked and unlocked positions causes movement of the latch bolt between an extended state and a retracted state to lock and unlock the door, and a motor operably connected to the link. A method of operating the exit device includes operating the motor to move the link in a first direction toward the unlocked position, the motor being operated until the link reaches a hard stop position; thereafter determining a soft stop position based on the hard stop position; and thereafter selectively using the motor to move the link in the first direction toward the unlocked position, the motor being operated only until the link reaches the soft stop position.
