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.

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.

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?

Potting and Encapsulation UV Adhesive

Master Bond (Hackensack, NJ) has introduced Master Bond UV10SP-2A, a one-component, flexible, UV curable polymer system for bonding, sealing, and coating with an attractive balance of pertinent physical, electrical, and chemical properties. The 100% reactive, moderate viscosity liquid at ambient temperatures does not contain any solvents or other volatiles. When exposed to a UV light source, Master Bond Polymer System UV10SP-2A cures as a durable, tough, non-yellowing system that can be used as an adhesive, sealant, and coating.
