Abstract: A lens assembly for a weapon sight includes a first lens having an optical axis and a focal plane array (FPA) coaxial with the optical axis of the first lens. A first parameter of the first lens is selected that minimizes an error in image shift when the weapon sight lens assembly is adjusted for focus. The first parameter of the first lens can be at least one of a lateral position, axial displacement, thickness, effective focal length, material, effective focal length, radius of curvature, conic constants, and higher order aspheric coefficients of the first lens. A sensor can detect a position of the lens and a processor can compare the measured position to an ideal position and use a lookup table to display a corrected reticle position or corrected scene. An actuator may move the lens to the ideal position from the measured position.

Abstract: A soft-kill countermeasure system utilizing a confirmation device, which may be radar, to enhance existing countermeasures, and enable new countermeasures to be utilized to combat the ever evolving and increasing sophistication of threats. The threat defeat confirmation may allow for rapid or immediate redirection of the countermeasure system to address additional simultaneous threats. The confirmation device can be mounted on a gimbal head or above a gimbal to take advantage of slewing movement to direct the confirmation signal towards the threat.

Abstract: The system and method of retractable solar arrays for underwater vehicles. In some cases, the retractable solar arrays for underwater vehicles contain anti-biofouling mechanisms. The retractable solar arrays may extend in a linear or a fan-like manner. In some cases, the solar array may be wrapped around the outside of the underwater vehicle or within a cylindrical housing. In some cases the solar array is a single flexible member with a series of connected panels.

Abstract: A laser mast for attachment to a ground vehicle includes a mast, a rotary stage, a platform, a first laser, and a second laser. The rotary stage is connected to and rotates the mast. The platform is connected to the rotary stage. The first laser is within the mast. The second laser is within the rotary stage or the platform.
