An exemplary status-indicating locking assembly includes a cylindrical lock assembly and a status-indicating assembly. The status-indicating assembly includes a sensor configured to sense the status of the cylindrical lock assembly, a transmission configured to communicate the lock status to at least one side of a door, and an indicator configured to display indicia relating to the lock status on the at least one side of the door. In certain forms, the sensor, transmission, and indicator may be electronic, mechanical, hydraulic, magnetic, or combinations thereof.

Status-indicating cylindrical lock assembly

An access control system for a plurality of door operators that are each respectively coupled to one of a plurality of doors providing an entrance to or exit from a building. A system controller monitors the status of each of the doors real time and controls the operation of each of the door operators based on the monitored status. The system controller adjusts the status of one or more door operators as a function of the determined status of one or more other door operators. Door operator commands are provided by the system controller to selected door operators to, for example, extend the opening time of one or more doors due to current activity by other door closers. The system controller is configured adjust the status of an entire group of doors or a sub-group group of doors depending on the status of the door operators.

Networked door closer and auto-operator

A lock device including a keyway sized and configured to receive a key, a sensor assembly including an optical source and a key height sensor, and a controller in communication with the sensor assembly. The optical source is configured to generate an optical signal, and the key height sensor is configured to generate a key height signal in response to receiving the optical signal. The key is configured to interact with the optical signal such that the key height signal varies based upon the height of the key. The controller is configured to generate a key profile based at least in part upon the key height signal, to compare the key profile to authorization data, to select an action based upon the comparing, and to perform the action.

Systems and methods for key recognition

An electrical generation system for a door positioned in a doorway includes a hinge arranged to support the door for rotational movement with respect to the doorway between a closed position and an open position, and a cam that is one of coupled to the door for movement with the door, and fixed with respect to the doorway. A piezo-electric generator is the other of coupled to the door for movement with the door, and fixed with respect to the doorway. The piezo-electric generator and the cam cooperate such that rotation of the cam with respect to the piezo-electric generator is operable to produce an electrical current in response to rotation of the door, and wherein the electrical current has a frequency that is greater than the number of revolutions made by the cam with respect to the piezo-electric generator.

System for harvesting energy from door or door hardware movement

An electrical generation system for a doorway including a door includes a lock mechanism movable between an engaged position and a disengaged position to allow the door to move between a closed position and an open position and a cam coupled to the door. A piezo-electric generator is coupled to the cam. The cam is rotatable with respect to the piezo-electric generator. The piezo-electric generator is operable to produce an electrical current in response to rotation of the cam with respect to the piezo-electric generator, and the electrical current has a frequency that is greater than the number of revolutions made by the cam with respect to the piezo-electric generator.

An exemplary iris-recognition method includes capturing a raw light field photograph of a face including an eye, locating the eye within the raw light field photograph, and rendering, from the raw light field photograph, an image focused on the eye. The image may include an eye portion including the eye. The method may further include extracting an iris template from the eye portion, determining a degree of match between the template and an authorized iris template, and performing an action in response to the degree of match.
