The Virtual Becomes Reality at Iowa State University

The colonel has a problem. He has eight unmanned aerial vehicles (UAVs) flying over the outskirts of Baghdad, looking for potential insurgent activity. Are those people he sees moving through the streets insurgents or are they a US infantry patrol? If he alters the flight path of one UAV to loiter over the suspicious activity, how should he deploy the other seven UAVs to pick up the first’s original mission? How does he keep track of the positions of the eight UAVs, what they are seeing, and the locations of nearby US troops, all in real-time?

Prototyping PMC Daughterboards

The PMC, or PCI Mezzanine Card, follows the IEEE P1386.1 standard for printed circuit boards. PMCs combine the electrical characteristics of the PCI bus with the mechanical dimensions of the Common Mezzanine Card, or CMC, format. Within the PMC format single PMC boards measure 74mm × 149mm. While the standard also defines a double-sized card, this format is rare. For PMC cards, as defined by the standard, connector configurations can be: 2 bus connectors (P1 and P2) supporting 32-bit PCI signals, 3 bus connectors (P1, P2 and P3) supporting 64 bit PCI signals, and/or 4th bus connector (P4) supporting non-specified I/O signals.

Techniques for Cooling Power and Other Electronic Devices

All electronic devices generate heat due to their unavoidable internal losses and inefficiencies. The higher the efficiency rating of the device, the less internal heat is generated within it. If we could achieve 100% efficiency, and technology is getting ever closer to that elusive goal, no heat would be generated within the device and, therefore, no cooling would be required. Until then, the generated heat must be dissipated to maximize the end product’s reliability and prevent its premature failure.

Intelligent Multi-Sensor Control Systems to Manage Lighting

Technology is needed to generate a change in the ambience of a given space. The technology must interpret a number of sensory changes within a room in order to change other parameters. Of specific interest is software that interprets multi-sensor data and the consequence hardware to control numerous devices to bring about a desired lighting change.

Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work even after cleaning, or — in the case of lawn and pond care — continue to make the soil or pond healthier even after fertilizing the plants or inoculating the water.
