Abstract: A method and a system for detecting and positioning an intruder within a specified volume are provided herein. The method may include the following steps: periodically scanning using a laser detection and ranging (LADAR) device directing a laser beam, within the specified volume; collecting reflections of the laser beam arriving from objects within the volume; converting the reflections to LADAR signal indicative of spatiotemporal presence of objects within the volume; applying signal processing algorithms to the LADAR signals, to determine a presence of an intruder and respective orientation parameters, based on predefined criteria; directing a camera based on the orientation parameters associated with the intruder for continuously capturing images of the intruder; and analyzing the images by a computer processor and instructing the camera to track the intruder based on the analysis, to yield real-time tracking parameters of the intruder.

Abstract: Method and system for unspinning a payload ejected from a spinning artillery projectile where the projectile is loaded with a cargo holding the payload and a payload unspinning device. The cargo is ejected from the projectile and the payload unspinning device is operated. The cargo includes a parachute and a shroud which covers the folded parachute and at least a portion of the payload. The payload unspinning device includes at least two yo-yo cords. Ejection of the cargo is followed sequentially by unwinding of the at least two yo-yo cords, liberation of the shroud, deployment of the parachute and stabilization of the payload.

Abstract: A method and a system for the detection of leaked fluid that leaked out of a fluid-carrying duct associated with at least one optical conductor. The method and the system monitor an aboveground portion of the duct along which the optical conductor runs. The mechanical mechanism includes a leaked-fluid collector configured to collect the leaked fluid, a leak-operated device configured to respond to the leaked fluid, and a strain application structure configured to use the leak-operated device to apply a strain deformation on the at least one optical conductor. The monitored leaks include leaks of liquid and leaks of pressurized gas. The leak-operated device is buoyant on the leaked fluid, or is a substance that expands in liquid, or is a hermetically sealed chamber.

Abstract: A scanning beam laser range finder and a method are provided for detecting an intrusion into a protected area by enhancing the capability of detecting an intruded attempting to blend with the area background. The laser range finder and method include an Emitter/Receiver configured to emit laser pulses towards each point out of the plurality of points and to receive therefrom reflected laser pulses. Further included is a processor coupled to the Emitter/Receiver and configured to derive an initial distance separating the laser range finder away from each point, the initial distance having an initial measurement error. At least one amplitude comparator is coupled to the Emitter/Receiver and to the processor, which is configured to derive a corrected distance to each point, the corrected distance having a corrected measurement error smaller than the initial measurement error.

Abstract: A system and a method for detecting an intrusion in an area by disposing a plurality of corner reflectors therein, interrogating and receiving successive response signals therefrom, and operating a control unit, coupled to a radar, the control unit being operative to compare and detect a change in returned signals for each one interrogation. A change to the returned signals, say above a certain threshold of change, may be proof that an intrusion had taken place.

Abstract: An intruder detection system for detecting the presence of an intruder in a protected area. A light beam, preferably from a laser, is reflected from a target, which is a potential intruder. The time period required for the beam to return to a light detector, as well as the intensity of the reflected light, is recorded. The system includes a computer and software for analyzing the measurements of distance and intensity of reflected light. The algorithm for detecting the presence of an intruder is based on changes in the measured distance and/or intensity of reflected light from initial measurements made during a “learning” period. The system tacks targets using data collected in consecutive searches of the area to be protected. Preferably, an alarm is sounded and/or a video camera is slaved to the system.
