The world through PC-powered glasses; with augmented reality what you get is more than what you see

Article Abstract:

Dr. Steven K. Feiner is developing a wearable computer which is designed to provide additional information to the user about their surroundings, via visual display. The technology functions as an 'overlay,' the wearer still hears and sees the environment. But a set of goggles would give directions, or list services nearby. A portable computer, connected wirelessly to a local network, underlays the system. A GPS transponder orients the information, so it appears where it should in the user's field of vision. The military is sponsoring part of Dr. Feiner's work.

Wiggling fans and other ways to keep a computer cool

Article Abstract:

Dr. Suresh V. Garimella and Dr. Arvind Raman from Purdue University have lead a team of inventors to deal with the heat from silicon chips with a fan whose blades are of piezoelectric ceramic materials. The blades move back and forth, quietly using little power consumption and taking up little space. Dr. Garimella, with Steven Wereley are also instilling microchannels into chips to conduct heat to other areas. Scientists are gearing up for new chips that will be able to throw off over 200 watts. Keeping cool will be a challenge.
