Abstract: A system and method for performing field measurement and testing of a plurality of widely spaced laser beams used in visual warning technology (VWT). VWT uses a combination of widely spaced laser beams, to warn civilians from approaching too close to military security areas. The widely spaced laser beams are displaced using rhomboidal prisms. Each rhomboidal prism receives a corresponding laser beam and displaces it toward a collecting lens. The lens focuses the displaced beams received thereon onto an imaging sensor for testing. Beam shutters may be used for selectively blocking one or more beams in order to test the beams separately and in different combinations.

Abstract: The present document describes a collection container or vehicle-mounted articulated arm for discharging bins in a collection container. The arm comprises an attachment section which allows for mounting the arm on a collection container or a chassis of a vehicle carrying a collection container without effecting any alterations to the existing mechanism/structure of the collection container and/or the truck on which the collection container is provided. The arm also comprises an articulation mechanism winch allows the arm to extend for grabbing the bin, lift the bin upward to discharge its content in the collection container, lower the bin to place it back on the ground, and retracts back toward the collection container for storage and/or transportation. An arm according to the present embodiments may be made from light materials such as aluminum without affecting its lifting capacity.

Abstract: The present document describes a kit for installation in a collection body, comprising a material receiver, for installation between the upper wall and the lower wall of the collection body, a tamping mechanism to allow the translation of materials disposed on the receptor and their discharge in the body, a packing mechanism to push the materials disposed in the body and compacting them.

Abstract: A laser warning receiver (LWR) to detect a very low power laser beam for a laser beam rider and provide a high angular resolution in determining the angle-of-arrival of that beam. An aperture having a fixed field-of-view (FOV) is located in a detection channel followed by a narrow-band filter and a detector whose output is applied to a pulse analyzer circuit. A localization channel with the same FOV has a similar narrow-band filter and a lens to focus light from that FOV onto a detector through a N×M element LCD matrix, an output of that detector being applied to the pulse analyzer circuit whose output is applied to a LCD pattern selector connected to the matrix which controls elements in the matrix to provide a transparent window of variable size and position. The size and position of that window allows a laser beam to reach the detector, the window being iterative reduced in size when a beam is detected to provide the location of its source.

Abstract: A guidance system for a missile with a laser beam source located at a distance from the missile generating a modulated laser beam that is directed towards the missile. A group of backward looking sensors on the body of the missile detect any radiation scattered from the laser beam along with a group of forward looking sensors located on the missile. Both groups look at an angle to the missile's longitudinal axis. Signals from the sensors are applied to processing electronics in the missile that determine the phase shift in signals derived from when a backward looking sensor detects scattered radiation from a laser beam and a forward looking sensor detects scattered radiation from that beam. The processing electronics can then accurately determine the distance between the missile and the beam from the phase shift and correct the missile's trajectory to maintain its position with respect to the beam.

Abstract: A guidance system for a missile utilitizes a laser beam source at a missile launch pad to generate a laser beam that is directed towards a target. A sensor on the body of a spinning missile detects radiation scattered from the laser beam, the sensor looking sideways and backward at an angle to the missile's longitudinal axis. Signals generated by that sensor are applied to a missile's guidance system's processing electronics that then determines the distance from the missile to the beam from the width of the signal generated by the sensor due to detecting scattered radiation from that laser beam. Once the distance between the missile and the beam is determined, the missile's guidance system corrects the missile's trajectory to maintain its position at a predetermined distance from the beam.

Abstract: An dithering system for implementation of a microscan that dithers an image on an array of sensing elements that defines an image plane by moving one or more lenses which displaces the image focused on the image plane. Piezoelectric positioners are provided to move the one or more lenses a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens horizontally and vertically or in a predetermined pattern provides dithering of the image so that microscanning can be employed.

Abstract: An imaging system for implementation of a microscan includes an array of sensing elements that define an image plane. A movable lensing system is adapted to focus an image on the image plane. Piezoelectric positioners are provided to move the lensing system a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens back and forth or in a predetermined pattern provides dithering of the image so that microscanning can be employed.

Abstract: A device for locking a container attached to two leaves of a container door. The device consists of two pieces, one attached to each leaf of the door. A locking bar is inserted through a set of rings, attached to the two pieces, that align when the container doors are closed. A feature of the device allows the relative adjustment of the rings. In one embodiment, a separate metal plate replaces one of the rings and secures the control levers of the vertical bars of the container.
