in this months technology review we cover a review of the technology and awarded patents for air delivery systems.  three are highlighted:  low-profile axial-flow single-blade piezoelectric fan; blade for a cooling fan; piezofan and heat sink system for enhanced heat transfer.   this technology review comes to coolingzone courtesy of our media sponsor, qpedia. 

we are presenting selected patents that were awarded to developers around the world to address cooling challenges. after reading the series, you will be more aware of both the historic developments and the latest breakthroughs in both product design and applications.   we are specifically focusing on patented technologies to show the breadth of development in thermal management product sectors.  please note that there are many patents within these areas. limited by article space, we are presenting a small number to offer a representation of the entire field.

you are encouraged to do your own patent investigation. further, if you have been awarded a patent and would like to have it included in these reviews, please send us your patent number or patent application. in this issue our spotlight is on air delivery systems using piezofan or standard fans. there is much discussion about its deployment in the electronics industry, and these patents show some of the salient features that are the focus of different inventors.
