A portable projection and display system can include a frame assembly having one or more folding trusses, a counterweight bar arranged on a rearward bottom portion of the frame to help provide a stable base, and an adjustable boom. A projector can be mounted on one end of an adjustable boom. The boom can adjust a distance between the projector and the display screen. The boom can be mounted to the frame with a hinged connection to permit it to act as a lever to raise and lower the projector. An adjustable boom bar can be attached to an end of the boom opposite the projector such that adjustment of the boom bar raises and lowers the projector via a lever action about a fulcrum.

A structurally supportive backer panel formed to fit within the recesses of a form liner to support the form liner when casting textured surfaces into concrete. The backer panel has a series of protrusions which fit within the recesses of the form liner in order to prevent the concrete pressure from deflecting and buckling the form liner. When the wet concrete is poured into a form fitted with the backer panel and form liner, the concrete fills the form and contacts the form liner, wherein the backer panel ensures that the shape of the form liner is not affected by the pressure and weight of the concrete.

This effort will support participation of the SPEC, Inc. instrumented Lear-25 aircraft and scientific support staff during the Ice in Clouds Experiment - Tropical (ICE-T), whose field phase is scheduled to occur during July 2011. The Lear-25 will complement the previously supported NSF/NCAR (National Center for Atmospheric Research) C-130 research aircraft by providing a highly agile platform capable of rapid climb rates during steep banking turns that will allow the rapid successive (every 1 to 2 min) penetrations of the key cloud region characterized by temperatures of -5 to -10 degC. It is in this zone where a combination of warm-rain and first-ice processes are anticipated to develop. This will in-turn allow the C-130 aircraft to concentrate on measurements in lower/warmer regions of the cloud and subcloud region, where it will document cloud condensation nuclei, ice nuclei and drop spectra measurements as well as collect upward-looking radar and lidar data encompassing the zone of Lear-25 operations. The complementary nature of these cooperating platforms will significantly increase the probability of achieving ICE-T scientific goals. The Learjet brings with it state-of-the-art cloud microphysics probes, including a new 3V-CPI instrument that combines the best features of the 2D-S (stereo) and cloud particle imager (CPI). The 3V-CPI is particularly well suited to detection of large (i.e., > 50 micron) drops that signify initiation of the warm rain process, as well as detection of first ice, which signifies the initiation of cloud glaciation.
The intellectual merit of this effort centers on increased understanding of ice initiation within growing maritime clouds and in turn its impact on precipitation formation, latent heat release and cloud dynamics, particle scavenging and chemical processes, electrical charge separation, water vapor content, and aircraft icing potential. Broader impacts will include interface with faculty and students at the University of Puerto Rico (UPR), where SPEC scientists plan to participate in the mini-conference, and potential interactions with a subset of these students in the field. Analyses supported through ICE-T are ultimately expected to enhance predictive capability of Earths hydrological and climate systems.

The explosive eruption of a volcano under the Eyjafjallaj¿kull glacier in Iceland on 14 April 2010 brought air travel in Europe and across the Atlantic to a standstill. Millions of passengers were stranded for over a week and the shutdowns cost the airlines $200 million per day. Jet airliner encounters with volcanic ash plumes have resulted in 90 known incidents of damage to engines and airframes over the past 30 years. Research aircraft measurements from the Mt. St. Helens eruption in 1980 showed that particles with diameters<0.1 micron were found in concentrations similar to those measured in ambient air, but concentrations with diameters from 0.1 to 30 microns were up to 100 times greater than in ambient air. A safe and cost-effective alternative to flying conventional research aircraft into volcanic ash plumes is to instrument a small Unmanned Aerial System (UAS) that uses electric motor propulsion. In Phase I we propose to design and laboratory test a novel, standalone sensor system that can measure the particle size distribution from 0.09 micron to hundreds of microns, record high-resolution digital images, and collect samples for post-analysis of the composition of volcanic ash. In Phase II we will install the sensor package on a tethered balloon and a small electric-powered UAS supplied by Vanilla Aircraft LLC. In concert with experts from the University of Alaska and the University of Cost Rica, we will perform a pilot field project measuring ash size distribution, recording high-resolution digital images, and analyzing ash composition in the plume of an active volcano in Costa Rica.
