Patent number: 8514076Abstract: An entrance denial security system comprises an entrance barrier closing an entrance into a secured area having a plurality of structural tubular elements with hollow cores forming a rigid integral barrier. At least one optical fiber sensor line is laced through the hollow cores of the structural elements for detecting a fault condition signifying an unauthorized intrusion attempt. A processor in communication with the fiber sensor line generates a fault signal in response to the occurrence of a fault condition and identifying the entrance where the fault condition occurred. A communication device operatively associated with the processor communicates the fault signal and an alarm so that a proper security response can be made to the fault condition. The system further comprises a plurality of intrusion sensors disposed at certain locations.Type: GrantFiled: January 22, 2008Date of Patent: August 20, 2013Assignee: Woven Electronics, LLCInventors: Douglas E. Piper, Sr., Thomas E. Browning, Jr., Mary Hester Owens, Clifford Leroy DeYoung

Patent number: 7956316Abstract: A sensor for a security system is disclosed to detect intrusions at one or more predetermined locations wherein each location includes a moveable member which must be moved in order to intrude the location. The system includes a fiber network routed in close proximity to one or more locations. The sensor comprises a sensor housing for being disposed at a location to detect a predetermined movement of the moveable member from a secure position to an unsecured position, and means for mounting the sensor housing in a stationary position at the location without a physical connection to the moveable member. The sensor housing includes a fiber inlet and a fiber outlet, and a fiber chamber for receiving a predetermined sensor fiber of the fiber network being routed through the sensor housing.Type: GrantFiled: January 23, 2009Date of Patent: June 7, 2011Assignee: Woven Electronics, LLCInventors: Thomas E. Browning, Jr., Mark C. Phillips

Patent number: 7852213Abstract: A security system is disclosed for detecting intrusions at a plurality of predetermined locations having moveable closure members. The system comprises a plurality of intrusion sensors disposed at the locations for detecting movement of the closure members. Primary and secondary optical fiber sensor lines are routed through the intrusion sensors, and primary and secondary scanning units pulse signals along the sensor lines and receive reflected signals back from the sensor lines. A processor processes the reflected signals to determine if a reflection and/or attenuation change has occurred in a reflected pulse signal signifying a prescribed level of unauthorized intrusion activity which matches a signature intrusion signal. In the event of a cut through in the sensor lines, the primary sensor line monitors the sensors downstream of the break, and the secondary sensor line is activated to monitor the sensors upstream of the break.Type: GrantFiled: August 6, 2007Date of Patent: December 14, 2010Assignee: Woven Electronics, LLCInventors: Thomas E. Browning, Jr., Randall E. Wooten, Mark C. Phillips, Mary H. Owens, Sam S. Shasteen

Patent number: 7800047Abstract: A computerized apparatus and method for detecting unauthorized activity in a protected area in real-time using a fiber optic cable having an optical sensor line, a fiber scanning unit, and a computer. Detecting unauthorized activity is done by scanning the sensor line using the scanning unit to obtain repetitive scan signals representing the state of the sensor line, receiving scan signals at the computer, processing the scan signals to determine an initial baseline representing the normal state of the sensor line, storing the baseline, continuously monitoring the sensor line using the scan signals received in real-time by the computer, comparing the scan signal to the baseline, determining if a fault has occurred based on an predetermined attenuation change in one or more of the scan signals as compared to the baseline, generating a fault signal, and providing a warning of a fault in response to the fault signal.Type: GrantFiled: March 17, 2005Date of Patent: September 21, 2010Assignee: Woven Electronics, LLCInventors: Thomas E. Browning, Jr., Mary H. Owens

Patent number: 7782196Abstract: An entrance denial security system for detecting a fault condition at one or more entrances into a secured area representing unauthorized activity and an attempt to gain entry through the entrance. The system comprising an entrance barrier closing an entrance into a secured area; the barrier including a plurality of hollow structural elements having hollow cores forming a rigid integral barrier; an optical fiber sensor line laced through the hollow cores of the structural elements of the gate for detecting the fault condition; a processor in communication with the fiber sensor line for generating a fault signal in response to the occurrence of a fault condition and identifying the entrance where the fault condition occurred; and a communication device operatively associated with the processor for communicating the fault signal so that a proper security response can be made to the fault condition.Type: GrantFiled: January 19, 2007Date of Patent: August 24, 2010Assignee: Woven Electronics, LLCInventors: Douglas E.

Patent number: 7755027Abstract: The invention consists of a secure data transmission cable for electronically transmitting secure data between remote locations in an exposed condition. The data transmission cable comprises a tubular outer protective layer, an inner core disposed within the outer protective layer, a data transmission line carried within the inner core for transmitting secure data between the remote locations, and a fiber optic sensor line included in the outer protective layer for detecting unauthorized activity relative to the transmission line. The fiber optic data transmission line comprises a plurality of optical fibers for transmitting data between remote locations and for detecting unauthorized activity relative to the transmission line. A protective casing surrounds the data transmission line for protecting the fiber optic data transmission line from contacting the outer protective layer. An outer protective casing braided around the core in which the sensor line is enclosed provides strength to the cable.Type: GrantFiled: October 22, 2007Date of Patent: July 13, 2010Assignee: Woven Electronics, LLCInventors: Thomas E. Browning, Jr., Douglas E. Piper, Sr., Mary H. Owens, Marko N. Veil
