Environmental samples are collected and analyzed using an unmanned aerial vehicle (UAV). In some examples, the sample is drawn into engagement with a sensor onboard a UAV by the existing fluid flow generated by a rotor fan through a duct of a ducted fan of the UAV. The quality characteristics of the fluid sample may be physically or wirelessly delivered to a remote location. In some examples, samples are drawn into engagement with the sensor by a flexible tube that is attached to an outer surface of the UAV. The flexible tube may allow the UAV to precisely target and collect samples of dust and moisture and other materials from the ground over which the UAV operates.

A circuit card module having increased cooling efficiency which comprises at least one printed wiring board (PWB), at least one component mounted on the PWB, a heatsink, an interchangeable frame, and a wedgelock for use with a chassis cold wall. One embodiment of the interchangeable frame comprises a protrusion so that it can be used with a convection-cooled chassis (fully compliant with IEEE 1101.2 Specifications). Another embodiment, for use with conduction-cooled chassis only (partially compliant with IEEE 1101.2 Specifications), is maximally efficient in removing heat as it does not include the protrusion. In the embodiment without the protrusion, the conduction contact area between the chassis cold wall and the frame is increased in width from approximately 0.25&Prime; to approximately 0.35&Prime;. In either embodiment, the wedgelock is mounted to one surface of the frame such that when installed in a conduction-cooled chassis, the opposite frame surface is forced against the chassis cold wall. In addition, the wedgelock can be enlarged to increase the clamping force over the contact area. The increased wedgelock size approximately doubles the clamping force applied. The net effect of these improvements are a reduction in the thermal resistance per inch of wedgelock length. This, in turn, reduces the module to chassis interface temperature rise of an exemplary 40 W module from 8.3&deg; C. to 4.15&deg; C. The improved thermal resistances and decreased temperature rises boost the reliability of the circuit cards, particularly in the stringent environments experienced in military applications.

An adapter for commercial off-the-shelf (COTS) circuit card modules resulting in increased cooling efficiency. COTS circuit card modules generally have at least one printed wiring board (PWB), at least one component mounted on the PWB, a heatsink or some type of heat path, a frame for supporting the cards, and a wedgelock for use with a conduction-cooled chassis. The adapter increases the cooling efficiency of such COTS modules while allowing them to remain compliant with IEEE 1101.2 Specifications. The invention is efficient in removing heat from the COTS circuit card modules as it increases the conduction contact area between the chassis cold wall and the COTS module. In addition, the adapter allows for the use of an extended width wedgelock to increase the clamping force over the conduction contact area. The extended width wedgelock is mounted to one surface of the frame such that when installed in a conduction-cooled chassis, the opposite frame surface is forced against the chassis cold wall. The increased wedgelock size approximately doubles the clamping force applied. The net effect of these improvements are a reduction in the thermal resistance per inch of wedgelock length. This, in turn, reduces the module to chassis interface temperature rise. The improved thermal resistances and decreased temperature rises boost the reliability of the COTS circuit cards, particularly in the stringent environments experienced in military applications.

Methods of and apparatuses for reducing the solar or infrared loading on display devices. A reflective material is positioned between a radiant energy source and the absorptive material of a display device to reflect wavelengths of radiant energy in the infrared or near-infrared range. The reflective material allows visible radiant energy to be transmitted, while reflecting the infrared radiant energy to reduce the infrared loading on the display device. The present invention reduces the temperature rise of the display device due to infrared loading by reflection rather than absorption of the radiant energy, while preserving the integrity of the visible wavelength range. The reflective material reduces the infrared loading on the display device by up to 50%.

A temperature sensor for the liquid crystal portion of a liquid crystal display assembly which includes a thin layer of transparent conductive material which is spread across the viewing area of the display. This layer of transparent conductive material can provide heat to warm up the display when a large voltage is put across it, and can also be used to measure liquid crystal temperature. It is known that the resistance of materials such as indium tin oxide (ITO) changes at a known rate with respect to temperature. By using this transparent layer of material in the stacked elements of a liquid crystal display assembly, an accurate reading of the liquid crystal temperature can be made.

The disclosure is directed to a color liquid crystal display backlight system for daytime and nighttime use. Night vision imaging system retirements are met so that light emissions from the 630 nm to 930 nm range are substantially reduced or eliminated. Separate daytime and nighttime light sources are utilized. The NVIS compatible nighttime source is positioned to be out of sight of a user and produces an appropriately filtered, substantially collimated beam which diffusively reflects from the inside walls and base of the display housing before it illuminates the display surface. Intensities of both daytime and nighttime light sources can be controlled.
