Patent number: 8256254Abstract: An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes an actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. In an unlocked state, the actuator moves the tumbler blocking member so that a movable locking member in the rotatable core that engages the outer body can be moved into the rotatable core. In a locked state, the actuator positions the tumbler blocking member to prevent the one or more tumblers from retracting and thereby retain the locking member in a channel of the outer body.Type: GrantFiled: December 27, 2007Date of Patent: September 4, 2012Assignee: UTC Fire & Security Americas Corporation, Inc.Inventor: Dirk L. Bellamy

Patent number: 8047031Abstract: An electronic lock includes a rotatable core movable within an outer body. The rotatable core includes a piezo-electric actuator configured to move a tumbler blocking member into or out of interfering engagement with one or more tumblers. Tamper circuitry coupled with the piezo-electric actuator is configured to resist an externally induced acceleration of the electronic lock by shunting electrical power produced by an externally induced motion of the piezo-electric actuator back to the piezo-electric actuator.Type: GrantFiled: December 27, 2007Date of Patent: November 1, 2011Assignee: UTC Fire & Security Americas Corporation, Inc.Inventors: Dirk L. Bellamy, Charles E. Seeley

Patent number: 7640773Abstract: According to one exemplary embodiment, a portion of a lock may include a stationary member having a bore, where the stationary member can be mountable to an object. The portion of the lock can also include a movable member positioned at least partially within the bore and movable relative to the bore in an unlocking direction during a normal unlocking operation. A deformable portion can be positioned adjacent an interface between the stationary member and the movable member. The deformable portion permits the movable member to move in the unlocking direction during a normal unlocking operation and is deformable to prevent movement of the movable member relative to the stationary member when subjected to excessive force applied in an attempt to move the movable member in the unlocking direction in other than a normal unlocking operation.Type: GrantFiled: October 19, 2005Date of Patent: January 5, 2010Assignee: GE Security, Inc.Inventors: Dirk L. Bellamy, Jon Marc Luebeck

Patent number: 7123127Abstract: A key management system for controlling access to vehicle keys includes a key set, a key container and an electronic access device. The key set includes vehicle keys to a particular vehicle and a key tag associated with the vehicle keys having an electronically readable identifier. The key container has a key set storage area secured by an electronic lock and a circuit that detects when the key set is stored in the key set storage area. The access device is carried by a user to access the key container, and has a memory that is updated with at least the identifier of the key tag when the key container is successfully accessed.Type: GrantFiled: January 31, 2003Date of Patent: October 17, 2006Assignee: General Electric CompanyInventors: Isaac J. Mosgrove, Teri Lynné Briskey, Dirk L. Bellamy, Sean Beebe, Scott D. Westfall, Dean Sinn

Patent number: 7061367Abstract: A decentralized key management system for controlling access to multiple vehicles among multiple users includes vehicle keys for the respective vehicles, individual locking key containers for the vehicles, electronic access devices for assignment to the users and a database. Each of the containers has a storage area within which a vehicle key or keys for one vehicle can be stored operable to unlock key containers if authorized. The access devices are operable to unlock the key containers if authorized. The access devices are programmable with information from the database such that an assigned access device is programmed with a specific user's access privileges for obtaining access to one or more of the vehicles in the system.Type: GrantFiled: November 14, 2003Date of Patent: June 13, 2006Assignee: General Electric CompanyInventors: Isaac J. Mosgrove, Teri Lynné Briskey, Dirk L. Bellamy, Sean Beebe, Scott D. Westfall, Dean Sinn, Ron Chapin, Adam Kuenzi, Jon Marc Luebeck, David Condon

Publication number: 20040025039Abstract: Security systems and methods control access at remote locations protected by electronic locks. Users open or otherwise manipulate an electronic lock via an electronic key device. The electronic key device may be an open architecture PDA programmed to function as an electronic key device, while retaining its general-purpose PDA functionality. Alternatively, the electronic key device may be a special-purpose device designed to function as an electronic key device. The key device and the lock box communicate with each other, preferably, by infrared techniques. The lock box and the key device are administered by a central authority via a central computer, which coordinates all security measures through the use of, e.g., frequent updates; tokens that the key device cannot read; checksums, including Message Authentication Codes; and encryption. A plurality of key devices may be programmed to open the same lock box. A key device may open a plurality of lock boxes.Type: ApplicationFiled: March 6, 2003Publication date: February 5, 2004Inventors: Adam Kuenzi, Susan Langford, Ron Chapin, John Buckley, Dirk L Bellamy, Anton K Diedrich
