Publication number: 20180051484Abstract: Electrified access-control technology devices for a door, particularly electrified locks for a door, having embedded circuitry therein, and methods of making the same. One or more printed circuit boards (PCBs) having various electronic circuitry are secured inside a housing that encases an access-control device, particularly a lock, for a door. The one or more PCB(s) may be embedded on an internal surface of the housing such that the embedded PCB resides inside the housing along with the lock itself. The embedded PCB(s) avoid interference of both any working components of the lock inside the housing and any openings residing in the housing.Type: ApplicationFiled: October 31, 2017Publication date: February 22, 2018Inventors: Daniel J.

Patent number: 9151096Abstract: A door release system including a capacitive circuit that includes a touch bar, a microprocessor within the touch bar programmed with noise-discrimination software to sense touching of the bar, and at least one micro-switch within the bar to function as a back-up that picks up movement of the bar to release the latch should the capacitive circuit fail. Optionally, a sign illuminated by LEDs and an antimicrobial coating/treatment may be applied to the bar. The system is intended for use on magnetically locked doors. The addition of the micro-switches that are actuatable by continued movement on the touch bar after the bar is initially touched provides a redundant access function initiated by other than the capacitive effect of human touch, which is expected to simplify use and ease accessibility for personnel with prosthetics or who may otherwise have their hands occupied.Type: GrantFiled: September 16, 2010Date of Patent: October 6, 2015Assignee: Hanchett Entry Systems, Inc.Inventors: Robert C. Hunt, Jonathan King, Larry Gene Corwin, Jr., Paul Justus Rodgers

Patent number: 8966259Abstract: An access control system including bi-directional communication between a controller and peripheral authentication devices utilized for selectively accessing a locked door is provided. The access control system provides components and circuitry to enable a user to securely assign and designate any card reader compatible card as an appropriate programming card and thereby activate or deactivate users and/or cards. The present invention further provides encrypted communication between the controller device and a PC.Type: GrantFiled: September 14, 2012Date of Patent: February 24, 2015Assignee: Securitron Magnalock CorporationInventors: Don Bartley, Larry Gene Corwin, Jr., Robert C.

Patent number: 8820803Abstract: An emergency exit door lock system configured to cooperate with a door hinged in a door frame for sensing when a person attempts to open the door, and for allowing the door to open after a subsequent delay. The system comprises an electromagnet affixable to a door frame for electromagnetically attracting an armature resiliently affixed at a variable armature separation distance to an armature mounting device, the device being affixable to the door. A proximity sensor including an analog Hall Effect device is mountable to the frame for detecting movement of the door away from a closed position. A controller, such as a micro-controller, receives a signal from the sensor and causes an alarm as a function of the signal. The signal is indicative of the armature separation distance, the controller being calibrate-able to provide a door alarm signal and door opening signal at any desired value of the armature separation distance.Type: GrantFiled: March 2, 2009Date of Patent: September 2, 2014Assignee: Hanchett Entry Systems, Inc.Inventors: Robert C. Hunt, Thomas Edward Roth

Patent number: 8495836Abstract: A drive mechanism for door hardware, such as a pushbar exit device, includes a driver for moving a component of the door hardware, a controller for controlling the operation of the driver, a sensor for detecting motion of the moving component and a spring connected between the driver and the door hardware component. The spring allows the driver to move for a period of time after the component has stopped moving. The controller monitors the sensor and moves the component until the sensor indicates that the driven component has stopped moving. The sensor produces an output signal and the controller detects an inflection point in the output signal when the component stops moving while the driver is still operating.Type: GrantFiled: August 27, 2009Date of Patent: July 30, 2013Assignee: Sargent Manufacturing CompanyInventors: Scott B. Lowder, Dale D. Martin, Jon Hulse, Robert C. Hunt, Arthur Limoncelli, Wai P. Wong

Patent number: 8094017Abstract: An electromagnetic lock monitoring system for monitoring the strength of a magnetic field in an electromechanical lock which is created when a steel armature plate is closed against an electromagnet. The system utilizes dual Hall Effect devices positioned in such a way that both ends of the electromagnet and both magnetic fields are monitored, and that the resulting monitoring effectively covers the complete contact surface between the electromagnet and the armature plate. Preferably, the Hall Effect devices are disposed in series at the point of maximum flux density within the center element of an E-shaped electromagnetic core, at opposite ends of the core. If the magnetic flux is below a preset limit, a relay also in series drops out, triggering an alarm which may be sonic, electronic, and/or visual, as is known in the prior art.Type: GrantFiled: December 30, 2008Date of Patent: January 10, 2012Assignee: Securitron Magnalock CorporationInventors: Robert C.

Patent number: 7984631Abstract: A modular escutcheon for a door lock including a plurality of covers. Each higher cover may progressively project outward from the surface of a door more than the covers below. Top and bottom edges of adjacent covers abut to form a joint, which may be partly or completely concealed resulting from the outward projections of higher covers. An escutcheon system may be provided that includes interchangeable parts, for example, there may be several different intermediate covers for use with the same lower and upper covers, or different upper covers that may be used in the same position. A variety of lock operating devices may be provided with the different covers to achieve different systems.Type: GrantFiled: February 22, 2008Date of Patent: July 26, 2011Assignee: Yale Security Inc.Inventors: Christopher N.
