Abstract: Image analysis is performed by defining segmentation boundaries within an image by using wavelet theory or some other suitable method. Such boundaries can be incomplete, irregular, and/or multi-valued. The segmentation boundaries are then incorporated into feature calculations related to fractal dimensions for each pixel using a diffusion related method or a Dijkstra potential related method. These features are then used in statistical techniques to distinguish among textures or classes of interest. The system performing the image analysis is trained (or supervised) on data from different classes within an image or images. This enables the system to then later identify these classes in different images. The system can be used for Computer Aided Diagnosis (CAD) of mammograms or other medical imagery.

Abstract: A switching arrangement is disclosed that interconnects a plurality of prssors forming a multi-processor computer system. The switching arrangement comprises optical delay lines that cooperate with microwave switching devices to, provide high speed switching of data packets of the multi-processor computer system. The optical delay lines temporarily store data packets for a sufficient time to allow for the contention resolution circuit to establish priority for any of the data packets that may be competing for a single source. The switching arrangement allows for the servicing of the data packets within a maximum of a few cycles of the clock rate of the computer system and a minimum of less than one clock cycle.

Abstract: A dual-purpose safety and retaining pin which performs the functions of sng the trigger assembly for a small arm and of securing the trigger assembly to the weapon is provided. The pin comprises a handle attached to a retainer and pin assembly which can be rotated to select safe or arm positions. The retainer and pin assembly is oriented in a specific rotational position with respect to the handle so that safing by rotating the pin can be accomplished. The pin has a cam configuration whereby rotation of the pin causes the cam to move a trigger connector link into contact with a hammer sear. This action enables the weapon. When the pin is rotated to the safe position or when the pin is removed from the trigger housing, the weapon is disabled. The pin is held in position by a plunger-ball locking arrangement. The single spring used to extend the plunger also acts as a detent engaging spring for securing the rotational position of the pin.

Abstract: A combination optical and iron sight system for a rocket launcher is provd. The combination sight system has a mounting bracket for attachment to a spotter rifle of a typical rocket launcher. A sight mounting bracket having an elevation adjustment and a windage adjustment is adapted for attachment to the spotter rifle mounting bracket. The adjustable sight mounting bracket has a mounting structure for an iron sight and a mounting bracket structure for an optical sight. Each sight, the optical sight and iron sights may be adjusted individually with respect to the adjustable bracket. Thereafter, adjustments to both sights can be made simultaneously by adjustment of the bracket itself in both windage and elevation.

Abstract: A system for determining whether a given phenomenon has occurred based on ltiple sensor decisions is provided. Each sensor samples input data and attempts to decide if the given phenomenon exists. These sensor decisions are provided to the data fusion processor. The data fusion processor uses a sum of the sensor decisions multiplied by a logarithmic gain indicating the relative reliability of each sensor to generate a test existence metric. The test existence metric is compared to two threshold limits. The results of this comparison are used to provide a final decision indicating the existence of the given phenomenon. An optimization is used to determine the threshold values used in the threshold table to guarantee that the false alarm rate and the data fusion processor is constant, even in cases where data from some sensor is missing.

Abstract: A mechanism for providing fine adjustment to achieve parallelism of a spong rifle barrel and a launcher tube is provided. The mechanism uses a convex spherical or near spherical surface on the rear of the spotter barrel which is mated to a concave conical surface on the spotting rifle receiver. The receiver is rigidly affixed to the launcher tube. The spotting rifle barrel axis is adjusted by means of three adjustment screws which act on a locating washer attached to the muzzle of the rifle. The locating washer has a spherical or near spherical surface whose radius center is co-located with the radius center of a second spherical surface supporting the breech end of the barrel. These spherical surfaces permit the free pivoting of the barrel about the common radius centers. A barrel gripping collar is moved into contact with the locating washer by means of a spring which forces the convex conical surface of the locating washer to engage the concave conical surface of the grip collar.

Abstract: A method of defending against toxic munitions which release airborne toxic materials is provided. The method includes the steps of detecting the physical properties of the airborne toxic material, detecting the physical properties of the munition, reading meteorological conditions at the location of the airborne toxic material, predicting the dispersion of the toxic munition, and modelling the predicted dispersion on a display monitor of a computer. The method also predicts the dispersion of an airborne toxic material at a known location.

Abstract: A method and system are provided for detecting objects at or below a surf of a body of water. A focused beam of amplitude varying electromagnetic radiation, e.g., a pulsed laser beam, is directed through the air towards the water's surface. Acoustic energy under the water's surface is monitored for any acoustic return that may be generated in the water as a result of the beam being incident on either an object at the water's surface or the water's surface above an object.

Abstract: A multiple strap carrier includes a base with a first strap passing under e base and extending beyond the base to form a first extension and a second extension. The first extension has loops thereon spaced apart from one another. One or more second straps also pass under the base. The first strap and second strap(s) cross one another under the base. Each second strap also extends beyond the base to form a third extension and a fourth extension. The third and fourth extensions each have loops thereon spaced apart from one another. Each of a plurality of tightening straps are attached to the second extension of the first strap. Each tightening strap passes through one loop on each of the first, third and fourth extensions. The loops are positioned such that the tightening straps are substantially parallel to one another.

Abstract: A fluid disperser is provided for dispersing a first fluid into a moving eam of a second fluid. After the first fluid is pressurized to at least twice the pressure of the second fluid, the first fluid is passed through a throat that increases the flow velocity of the first fluid to supersonic. A fluidic oscillator, coupled to the output of the throat, has a central axis of symmetry, a first end by which the first fluid enters the oscillator and a second end by which the first fluid exits the oscillator. The oscillator includes two opposing walls that diverge symmetrically about the central axis from the first to the second end at an angle of divergence relative to the central axis that causes the first fluid entering the first end to attach to either of the two opposing walls and continue therealong to the second end.
