Visible amounts of light from nanoamperes of power. Special fabrication structure to focus light reduces side scattering.

Quoted: The Tyndall National Institute in Cork is developing micro LEDs that operate from tiny amounts of power.

Parasitic power source.

Quoted: the camera obtains power by using the magnetic field generated by the AC source (45-100kHz) in the fluorescent light

Physorg.com always has a wide variety of interesting one-page articles, even though most of them are essentially press releases.

Quoted: A sample of the new nanocomposite paper developed by researchers at Rensselaer Polytechnic Institute. Infused with carbon nanotubes, the paper can be used to create ultra-thin, flexible batteries and energy storage devices for next-generation electronics and implantable medical equipment

The Federal Circuit's first precedential post-KSR decision on the question of obviousness. We are indeed witnessing a sea change.

The phrase that pays, quoted from SCOTUS in this decision:
“The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.”

Words to litigate by.

Possible Flash memory replacement. Smaller cell size than Flash memory, 3X faster, 1000x greater # of write cycles, scales better to new fabrication processes. An odd, old technique. Useable, cost-effective prototypes have been demonstrated.

Cool custom implementation of the Paia Theremax-brand theremin:

Way cool electronica on MySpace.

Quoted: music for the un-squares

Dotted from Mike. Today's super-efficient LEDs (lots of light output per short, limited power pulse) & faster MCUs make this a very practical alternative. Cost is still an issue: efficient LEDs are much more expensive than extra MCU pins, the alternative may be a dim and/or flickering display.
