Abstract: A method of providing a defense against a shaped charge uses an outer and an inner armor layer provided with a medial space between these outer and inner armor layers. One or more defensive shaped charges are positioned in the medial space. If the outer armor layer is attacked by ordnance having an offensive shaped charge, one or more of the defensive shaped charges positioned in the medial space is detonated so as to degrade the effectiveness of the offensive shaped charge and prevent penetration of the inner armor layer.

Abstract: A method for correlating an image to align two sensors comprising the steps of centering an imaging unit on a landmark that provides good contrast and distinct edges so as to provide a scene, taking a snapshot of the scene from both sensors, applying a Sobel edge filter to the image from both sensors to create two strong edge maps, cropping a small block of one image centered about the landmark and cross-correlating it on a larger region centered on an expected position of the landmark in the other image, and from the position of the strongest correlation peak determining the position of the center of the block from the first image, providing the difference in the alignment of the two sensors.

Abstract: An algorithm system to detect a broad class of signals in Gaussian noise using higher-order statistics. The algorithm system detects a number of different signal types. The signals may be in the base-band or the pass-band, single-carrier or multi-carrier, frequency hopping or non-hopping, broad-pulse or narrow-pulse etc. In a typical setting this algorithm system provides an error rate of 3/100 at a signal to noise ratio of 0 dB. This algorithm system gives the time frequency detection ratio that may be used to determine if the detected signal falls in Class Single-Carrier of Class Multi-Carrier. Additionally this algorithm system may be used for a number of different applications such as multiple signal identification, finding the basis functions of the received signal and the like.

Abstract: A compact, purely mechanical wing deployment assisting mechanism uses torsion springs and lever arms to apply a deploying force to a guidance wing during its initial deployment through a wing slot in a rocket or missile, thereby assisting the wing to burst through a cover seal protecting the wing slot. The wings are then fully deployed by centrifugal force. Various embodiments include two “extreme duty” springs and two lever arms per wing, working in parallel. Embodiments provide a total of at least 24 pounds of force per wing at the end of a spring travel of 0.30 inches. In some embodiments, the entire mechanism weighs less than 0.5 pounds and/or occupies less than 2.5 cubic inches per wing. In embodiments, an assembled group, including two springs and two lever arms, is located between each pair of wings, whereby each assembled group applies one lever arm to each adjoining wing.

Abstract: Each of a number of gateway network radios operates with a transmission protocol of an associated one of plural incompatible communication networks. Each network radio has an audio terminal for producing first audio signals detected from transmissions of user radios in its associated network, and a microphone terminal for receiving second audio signals for transmission to the user radios. A voice bridging gateway server has multiple ports each corresponding to one of the networks for coupling to the network radio associated with the one network. Each port receives the first audio signals from the audio terminal of the associated network radio, and produces the second audio signals for applying to the microphone terminal of the network radio. The server implements a private branch exchange application whereby user radios in a given communication network can be voice bridged with user radios in a selected one or more of the other networks.

Abstract: A gunner protection system for positioning armored panels around a hatch opening and a mounted weapon or equipment system. The armored panels are arranged to create an armored envelope surrounding the vehicle hatch and defining an opening through which the weapon or equipment system can be operated. The armored panels can be individually raised to define a portion of the armored envelope or lowered to change the geometry of the armored envelope or opening according to the particular weapon or equipment system. Similarly, all of the armored panels can be lowered to collapse the armorer envelope to allow for efficient transport of the vehicle with the gunner protection system attached to the vehicle.
