Patent number: 11190271Abstract: In a monitoring system using optical fibers, an area to be monitored is divided into zones where each zone has fibers which create a change in a signal transmitted by the fiber in response to an event to be monitored. The fibers all communicate to a common monitoring system having a channel for each zone. The fiber of a second one of the zones communicates to the respective channel of the common monitoring system through a fiber passing through a first one of the zones so that the fiber and thus the second channel is also responsive to an event in the first zone zones. The invention provides a method of distinguishing between the separate zones where events have occurred by a Boolean analysis of the signals in the different channels.Type: GrantFiled: March 4, 2021Date of Patent: November 30, 2021Assignee: Network Integrity Systems, Inc.Inventors: Cary R.

Publication number: 20210156106Abstract: A system for detecting an intrusion of at least one of a monitoring fiber and a detector comprises a sensor having a closure monitor and an intrusion monitor, the closure monitor including a signal generator and at least one detector attached to the monitoring fiber. The signal generator transmits signal light such that the monitoring fiber receives the transmitted signal light and reflects a portion of the signal light via the at least one detector to the closure monitor and transmits a non-reflected portion of the signal light. The intrusion monitor receives the transmitted non-reflected portion of the signal light, and monitors the non-reflected portion of the signal light to detect transient changes in the non-reflected portion of the signal light indicative of at least one of a vibration, a motion and a handling of at least one of the monitoring fiber and the at least one detector.Type: ApplicationFiled: January 29, 2021Publication date: May 27, 2021Applicant: Network Integrity Systems, Inc.Inventors: Cary R.

Patent number: 10600294Abstract: A method is provided for detecting intrusion into an optical cable of a single mode optical fiber network comprising where monitoring light signals are transmitted along a telecommunications optical fiber to be monitored either along a fiber additional to a data fiber or by multiplexing onto a common fiber. The received monitoring light signals after transmission along the telecommunications optical fiber are analyzed for changes indicative of movement of the optical fiber for detecting an intrusion event. The monitoring light signals at the receive end of the fiber signals are monitored by feeding the signals from the single mode fiber into a multi-mode fiber in a manner which causes changes in modal power distribution which can be detected by taking a portion only of the modes.Type: GrantFiled: August 16, 2019Date of Patent: March 24, 2020Assignee: Network Integrity Systems, Inc.Inventors: Cary R.

Patent number: 10263696Abstract: An optical fiber is monitored for changes in a monitor signal caused when the fiber is subjected to vibration, motion, or handling typical of an intrusion attempt and for triggering an alarm condition in response by one or more sensors. The sensor emits data on each disturbance event including the existence of the disturbance event and a value associated with the disturbance event dependent on an intensity of the disturbance. The arrangement herein provides an algorithm to analyze the disturbance events which calculates for each event a score dependent on the presence of the event and the value associated with the event, generates a summation of the scores in a FIFO and when the summation of the scores exceeds a predetermined threshold within a predetermined time period, the processor emits a signal triggering the alarm condition.Type: GrantFiled: June 11, 2018Date of Patent: April 16, 2019Assignee: Network Integrity Systems, inc.Inventors: Cary R.
