Flexible-Actively Controlled Heat Exchanger Based on Thin-Film Technology
Published Wednesday, May 7, 2008The microscale heat exchanger manufactured using the wafer technology can’t be scaled for large applications. Also macroscale heat exchangers are usually rigid and require fins to have a secondary heat transfer area for better heat transfer on the air side. Besides, installing bypass valves and temperature sensor in conventional heat exchanger can...

Low Profile F-Inverted Compact Antenna (FICA)
Published Wednesday, May 7, 2008The antenna size is one of the major limitations in miniaturizing wireless communication equipment. Chip antennas and planar inverted F antennas (PIFAs) have already appeared on the market due to their low profile, small size and effective integration with transceiver chips on circuit boards. However these antennas perform well only if a ground...
