Embedded Power Conference Strives to Fill Power Vacuum
September 22, 2008 12:19 pm | by Jason Lomberg, Technical Editor | Blogs | CommentsFrom September 17-18, the Marriott Hotel in San Jose hosted the first annual Embedded Power Conference, focusing on “increasing power-management issues.” I attended this inaugural event, and it was well worth the price of admission (press get in free). Seriously though, it was a great first effort, and will fill a void in the industry. Embedded Power was comprised of over 20 lectures, classes, and discussions. The highlight (in this humble editor’s opinion) was a panel moderated by ECN’s skipper, Alix Paultre. Entitled “Open-Source vs. Proprietary Methodologies in Digital Power Management,” the panel addressed a hot industry topic in a town hall format.
