Patent number: 6072402Abstract: A secure entry system makes use of radio transmissions to communicate with locks, keys, and related components throughout the system. The radio transmissions can be made using a paging system, a cellular telephone system, or any other RF carrier. Some embodiments employ a cellular telephone in lieu of an electronic key. Others integrate a paging receiver within an electronic key to provide a unit with dual functionality. The system is illustrated with reference to exemplary applications in the industrial site security, real estate lockbox, and transportation fields.Type: GrantFiled: January 9, 1992Date of Patent: June 6, 2000Assignee: SLC Technologies, Inc.Inventors: John M. Kniffin, Ron McCauley, Ralph H. Wells, III, John W. Sherman, Wayne F. Larson

Patent number: 4947163Abstract: A key for an electronic lock system is provided with circuitry capable of performing a plurality of lock-related functions. Stored in the key is characterization data that determines the key's particular functionality be electronically disabling certain ones of these functions, leaving just a subset of functions from which the operator may select. Keys having various capabilities can thus be electronically tailored from a single master design.Type: GrantFiled: September 11, 1989Date of Patent: August 7, 1990Assignee: Supra Products, Inc.Inventors: Walter G. Henderson, John Q. Archer, II, Gerald R. Daum, George A. Ellson, John E. Gray, Wayne F. Larson, Rockne M. Olds, Jerry P. Scansen, John W. Sherman, Edgar J. Urein

Patent number: 4914732Abstract: An electronic key for an electronic lock system is provided with graphical user interface which can display a plurality of symbols corresponding to a plurality of functions that the key can cause the lock to execute. An operator of the key moves a visual indicia among these symbols to select a desired function. The key then transmits instructions to the lock causing the selected function to be executed.Type: GrantFiled: September 8, 1989Date of Patent: April 3, 1990Assignee: Supra Products, Inc.Inventors: Walter G. Henderson, John Q. Archer, II, Gerald R. Daum, George A. Ellson, John E. Gray, Wayne F. Larson, Rockne M. Olds, Jerry P. Scansen, John W. Sherman, Edgar J. Unrein
