Abstract: In one general aspect, a communications system as described herein provides a wide-band jamming signal that is digitally created, conditioned, and modified by a processing based system to provide open data channels to authorized parties within a jammed communications band. The communications system modifies and maintains the open data channels to sustain communications between authorized devices. In addition, the communications system provides frequency hopping using the open data channels to supply secure data links to authorized devices within the jammed communications band while denying service to unauthorized communication nodes or devices.

Abstract: A system for sampling a moving fluid utilizes a housing in the shape of an airfoil having a leading edge adapted to be disposed in the moving fluid such that the moving fluid will initially encounter the leading edge. A fluid flow pathway extends through the airfoil. One or more sampling ports are formed in the airfoil on the airfoil's high pressure side. Each sampling port is in fluid communication with the fluid flow pathway. The system can also have one or more control ports formed on the low pressure side of the airfoil. Each control port is in fluid communication with the fluid flow pathway. The housing can be mounted to experience two rotational degrees of freedom, and can have an aerodynamic tail assembly coupled thereto.

Abstract: A gun control system is disclosed that includes a fire control kernel and location-independent software components within the fire control kernel. The kernel provides core fire control functionality that is unaffected by changes within the external environment, such as changes to the physical configuration of the gun system of which the gun control system is a part. Each location-independent software component has a specific functionality, and is able to run on any processor within the system in a location-independent manner. These software components can include a target/track management interface software component, a gun control system control interface software component, a gun mount control interface software component, an ownship data interface software component, and a gun control system display interface software component.

Abstract: Actuators already present as an integral part of the control systems of missiles and the like are used to activate and control the deployment of fins and the like without the need for separate explosively or mechanically driven fin deployment systems. Springs located in hinges on the fins accomplish the complete deployment of the fins after proper orientation by the actuators.

Abstract: A fragmenting projectile includes a multi-wall projectile casing with each wall thereof formed by a sleeve. Each pair of adjacent sleeves is defined by inner and outer sleeves that mate in a threaded engagement. Explosive material is disposed in an innermost sleeve.
