Researchers debut one-cubic-millimeter computer, want to stick it in your eye

By Christopher Trout posted Feb 26th 2011 5:43PM This as-of-yet-unnamed mini computer was fashioned as an implantable eye pressure monitor for glaucoma patients, but its creators envision a future where we're all crawling with the little buggers. Taking up just over one cubic millimeter of space, the thing stuffs a pressure sensor, memory, thin-film battery, solar cell, wireless radio, and low-power microprocessor all into one very small translucent container. The processor behind this little guy uses an "extreme" sleep mode to keep it napping at 15-minute intervals and sucking up 5.3 nanowatts while awake, and its battery runs off 10 hours of indoor light or one and a half hours of sun beams. Using the sensor to measure eye pressure and the radio to communicate with an external reader, the system will continuously track the progress of glaucoma, without those pesky contacts. Of course, the mad scientists behind it look forward to a day when the tiny device will do much more, with each of us toting hundreds of the computer implants all over our bodies -- looks like a bright future for cyborgdom.

Firefox 4 beta 5 for mobile released, available on Android, N900, your computer

Tired of using the default browser on your smart phone to browse Engadget? Got a thing for Firefox? Great, 'cause Mozilla just pushed out the fifth beta of Firefox 4 for mobile. You might be familiar with the on-the-go version of Mozilla's creation, but if not, here's your chance to grab the latest (and probably) the most stable build to date. In addition to the Android and Maemo version, the company has released a Fennec build for use on Windows, OS X and Linux.
We tinkered with the OS X build of the browser on our Macbook Pro and although pages appear to render quickly, we can't quite figure out how to navigate backwards. You can pinch-to-zoom with the trackpad and scroll with the d-pad, but once you've loaded a page, it seems you need to be on a mobile device do any further navigation. Of course, as you'll see in the gallery below, the beta comes packed with the usual -- preferences, downloads, add-ons, bookmarks and Firefox Sync. If you want to give the software a whirl, hit the source link to grab the build of your choice.

Eighth Circuit declares RAZR a computer under federal law

There's little doubt that today's smartphones are pocketable computers -- they're equally or more powerful than the desktop PCs of yesteryear -- but what about dumbphones? Well, in US v. Kramer, the Eighth Circuit Court of Appeals just held that a Motorola Motorazr V3 fits the federal statutory definition for a computer -- and quoted Woz in the opinion: "Everything has a computer in it nowadays." Seems a bit silly to call a RAZR a computer, but courts can only interpret existing laws, not make new ones -- and US law says a computer is "an electronic, magnetic, optical, electrochemical, or other high speed data processing device performing logical, arithmetic, or storage functions." Because this was the first time a federal appeals court had ruled on the issue, the Eighth Circuit set a precedent that other courts are likely to follow. And yes, the court is aware such a definition may include microwaves and coffee makers, and informed Congress that it should change the law if it doesn't like it. Regardless of whether you agree, this interpretation added some jail time for a guy who pled guilty to trying to engage in sexual activity with a minor, so the mild absurdity of it all is fine by us. Somewhere Chris Hansen is smiling.
