LASER SOURCE ASSEMBLY WITH THERMAL CONTROL AND MECHANICALLY STABLE MOUNTING
A laser source (340) that generates an output beam (354) that is directed along a beam axis (354A) that is coaxial with a first axis and orthogonal to a second axis comprises a first frame (356), a laser (358), and a first mounting assembly (360). The laser (358) generates the output beam (354) that is directed along the beam axis (354A). The first mounting assembly (360) couples the laser (358) to the first frame (356). The first mounting assembly (360) allows the laser (358) to expand and contract relative to the first frame (356) along the first axis and along the second axis, while maintaining alignment of the output beam (354) so the beam axis (354A) is substantially coaxial with the first axis. The first mounting assembly (360) can include a first fastener assembly (366) that couples the laser (358) to the first frame (356), and a first alignment assembly (368) that maintains alignment of the laser (358) along a first alignment axis (370) that is substantially parallel to the first axis.
Light shield device
A visual impairment device includes a power supply, an intense light source having two or more beams of intense light with different peak wavelengths and a wavelength bandwidth less than 50 nm, a modulator and a control circuit. The modulator operates to modulates the two or more beams of intense light to produce a spatial array such that at least one of the beams used to produce the spatial array has the requisite irradiance to cause visual impairment. In some examples, the beams of intense light are laser beams. Also included are methods of using the device to cause visual impairment of an intruder who enters a visual impairment zone created by said device.
HYPER HEMISPHERE UNITARY DOME FOR A DEFENSIVE INFRARED COUNTERMEASURE SYSTEM
A counter measure system is provided having a unitary infrared transparent dome including a look angle greater than 180. The dome has two hemispherical regions, with a second region having a truncated bottom end defining an opening to a central cavity inside which electro-optical elements are disposed. The electro-optical elements can view outward through the dome at the look angle. The second region on the dome has a complementary curvature as the first region by continuing a similar radius beyond a transverse horizontal axis or equator. The dome is mounted to a base, which also may be referred to as a bezel. The base defines a rabbet extending circumferentially about the base imaginary center defining an aperture. The base and the dome are formed from different materials but have equivalent coefficients of thermal expansion. In one embodiment the dome if formed from sapphire and the base is titanium.

TRANSPARENT DISPLAY WITH EYE PROTECTION
A transparent display provides eye protection from lasers and other high intensity light sources. The transparent display allows users to view objects clearly through the display while also presenting text, graphics or video on the display surface. Simultaneously, the display assembly comprises a component that provides eye protection against high power radiation sources. The transparent display with eye protection provides both protection from high power light sources and an additional cockpit display surface for presentation of information including graphical images, symbology, video, text, and other data.
DETECTING AND LOCATING BRIGHT LIGHT SOURCES FROM MOVING AIRCRAFT
A method and system for a light source detection system, comprising an aircraft carrying at least one camera. The system includes a database for storing information about the aircraft's motion, direction, and position and ground location information, such as the onboard navigation system database or an remotely accessible database. The system also includes a processor that accesses the database and is connected to the camera. The processor uses image analysis and processing techniques to determine the ground location corresponding to the light source from an image of that light captured by the camera. It determines the path traveled by that light and estimates its location as being a pre-selected distance vertically above the ground along the path traveled by the light to the aircraft when the image of the light was captured.
