Nokia's N96 Now Official, Quad-Band and WCDMA
After much leaking of information, Nokia's N96 slider cellphone is now official. It's a quad-band, US 3G-enabled (WCDMA) phone with a 2.8-inch screen, 16GB of built-in memory, a 5-megapixel Carl-Zeiss Tessar lens, A-GPS and 802.11 b/g Wi-Fi.

Firefox 3.7 Theme Makes Your Browser Look Awesome
Windows only: Mozilla released their version 3.7 theme mockups only a few days ago, but you don't have to wait for the 3.7 release to enjoy them—a motivated user already created a lookalike theme that you can install now. (Click the image above for a closer look.) Installing this theme isn't q
New Treatment Filters Bacteria From the Bloodstream with an Electromagnet
This may sound like something out of Iron Man, but it's very real. Don Ingber has developed a machine that uses an electromagnet to suck sepsis-causing bacteria out of the blood. In lab tests, Ingber's team mixed donor blood with the fungus Candida albicans, a common cause of sepsis, and added plast
Intel Big on 32nm Westmere Processors for Consumers in 2010
At today's San Francisco event, Intel mostly discussed what we know about the upcoming Westmere processor, but revealed they're scrapping the next dual-core 45nm processors, in favor of 32nm Westmere chips in early 2010. The first Westmere chips will be the dual-core Clarkdale and Annendale pr
New Method of Writing Hard Drives Could Yield 1TB Per Inch Density
Current hard disk drives are up against their ceiling: a few hundred GB per inch. But a combination of two unique writing methods could lead to new HDDs that pack ten times as much data in the same space. A new paper in the journal Nature Photonics outlines the process, which combines TAR (thFuture iPhones May Have Always-On Display

Apple has patented a new display technology that will allow their iPhones to have always-on displays with almost no battery cost whatsoever. This doesn’t mean the whole display would be lit at all times. In reality, only part of it would be activated using a secondary backlight system located under the main one. According to Apple, the objective is to give feedback to the user at all times, even when the main display is turned off:
The primary backlight system may block light from the secondary backlight system except for those one or more regions. Thus, the size and shape of the status indicator may be set by sizing and shaping the transparent or semitransparent regions of the primary backlight system. In addition to setting the size and shape of the icon, the color of the icon may also be set by adjusting the color of the light provided by the secondary backlight system.
For example, each indicator may have a particular color, blinking speed, or light intensity. These properties may be programmed into the electronic device by the user, or may be hard-coded or hard-wired into the system. Thus, when the secondary backlight is turned on, the properties of the light provided by the secondary backlight system may depend on the status of the device. Also, if the status of the electronic device changes while the secondary backlight is on, the properties of the light provided by the secondary backlight system may change to reflect the new status.
To avoid depleting the battery, these icons’ backlight system will be low-power. Don’t get your expectations too high, however. The patent doesn’t clearly explains how the icons themselves may be displayed. By the look of the diagrams included, they may not even be actual pixel-based icons, but cut-outs illuminated by individual LED lights shining through the main display.
But of course, you know that this may be something completely different from what the diagram shows, since the drawings included in patents always seem to be drawn by a monkey on drugs. At least, I want to believe this thing is more like the illustration I did, because if it’s just little icons—like every other single cheap clamshell cellphone out there—I won’t be very excited.
