Abstract: Methods and apparatuses for providing an adjustable flow resistor. The adjustable flow resistor can include a chamber into which fluid is introduced, having an input end and an output end. A flow modifier can be situated within the chamber, between the input end and the output end, to modify a flow rate of the fluid. An adjustable resistance member can be positioned to interact with the flow modifier within the chamber to controllably modify the constant flow rate out of the adjustable flow resistor.

Abstract: Systems and methods for exhausting air from a flow pathway are provided. The systems can include a flow resistor having an input coupled to a fluid source and an outlet to output a fluid at an output flow rate, the flow resistor including an adjustable flow channel for modifying the output flow rate of the fluid flowing through the flow resistor; and a priming device having an elongated portion, the elongated portion being substantially rigid axially and configured for insertion through the outlet of the flow resistor to engage the flow resistor and adjust the output flow rate to allow air to be exhausted from the flow pathway through the flow resistor.

Abstract: A bendable glass and substrate assembly including a glass panel that has a planar pre-installation geometry and first and second panel surfaces that are separated by a panel thickness and at least one substrate that is bonded to at least a portion of the first panel surface. Both the glass panel and the substrate are made of bendable materials and are adapted to take on at least one bent post-installation geometry that is different than the planar pre-installation geometry. The bendable materials of the glass panel and the substrate remain flexible and resilient even after the substrate is bonded to the glass panel and as a result the bendable glass and substrate assembly has a planar geometry before installation and is bent to a final non-planar shape or contour when the bendable glass and substrate assembly is mounted in a final installation.

Abstract: A system and method for simulating realistically sized emission signature of a weapon system or weapon platform for the purpose of testing an optical detection device at a long distance in the field. The system utilizes an image screen with a curved imaging surface that is positioned at least one kilometer away from the optical detection device being tested for example. The optical testing device observes the image screen through ambient environmental conditions. A projection device is provided at a first distance from the image screen. The projection device projects a simulation of the emission signature onto the curved imaging surface. The curved imaging surface reflects the simulation toward the optical detection device. A focusing system can be used to adjust the reflection so that the simulation is collimated, converging or dispersing as it progresses toward the optical detection device.

Abstract: A system, method, and device for simulating an emission signature, which contains representative intensity, temporal, and spectral emission profiles of a weapon system or weapon platform for the purpose of testing an optical detection device. A projection system optically projects the emission signature. A projection screen is provided that has a concave curvature. The concave curvature possesses a first focal point and a second focal point. Any light emanating from the second focal toward the projection screen is reflected by the projection screen toward the first focal point. The projection system is positioned at the second focal point and the optical detection system is positioned at the first focal point. In this manner, the emission signature projected by the projector system is redirected to the optical detection system.

Abstract: A diode laser beam combining apparatus for producing a high combined beam power density in the far field at reduced levels of power consumption and heat dissipation includes an array of semiconductor laser emitters arranged in a collinear manner with respect to each other and having an emitter pitch between about 0.7 mm and 2.5 mm. The apparatus also includes a cylindrical lens for collimating emitter beams generated by the array of laser emitters in a direction perpendicular to a junction plane of the laser emitters. The apparatus further includes a micro-optic array and a long focal length cylindrical lens. The micro-optic array is configured to perform a rotational transformation of the collimated emitter beams. The micro-optic array has a lateral spacing in a direction parallel to the junction plane of the laser emitters that matches the emitter pitch.
