The North American Eagle vehicle.
(Credit: Landspeed.com)If you haven't heard of North American Eagle, it's a program to break the existing land-based speed record of 763 miles per hour by reaching 800 mph, which is slightly faster than Mach 1 (768 mph).
There are a range of technologies incorporated into the NAE vehicle to make this crazy land speed possible, including those that provide communication between car and control center. This is where Tropos Networks comes into play.
The company announced Tuesday that its routers are being used in the latest NAE trial runs in the desert at Black Rock, Nevada, this week, where vehicle speeds exceed 500 miles per hour. Onboard the NAE vehicle during its high-speed test runs is a Tropos 4210 mobile mesh router that provides real-time communication and data monitoring.
While network connection at high speeds is not new, as Internet access on airplanes has been available for some time now, the main issue here is latency. The NAE vehicle is a very-fast-moving land-based testing object, and it's necessary that it has the capacity for true real-time communication.
To resolve this, Tropos system uses direct Wi-Fi links between the vehicle and ground stations to provide access to vehicle data with a delay of only one to three milliseconds. ... Read more
This is a test clip of some birds that I took using the Casio Exilim EX-FH20's high-speed video capture. (I know it's not the most exciting clip in the world, unless you're into watching 6 minutes of birds bathing in public, you sicko.) This feature is really pretty cool (as is the camera's 40-frame-per-second shooting speed), though I'm still on the fence about how much someone would actually use it after the initial "wow, this is cool" phase.
But Casio deserves credit for pulling off the high-speed shooting features on the Exilim EX-FH20 at its sub-$500 price. It really makes me look forward to testing the two less-expensive Casio Exilim ultracompacts with these features, the EX-FC100 and the EX-FS10. Unfortunately, the photo quality on the FH20 seems to have taken a back seat to its speedy shooting, and usability isn't too great, either.

Transcend, the company that introduced a solid-state-drive-based external drive the other day, on Thursday unveiled its 192GB Solid State Drive.
Despite the mundane name, the new drive is equipped with NAND flash memory and offers up to 192GB of storage, a fast sustained read performance of up to 150MBps, and up to a 90MBps write performance, according to Transcend. Its latency is rated at 0.2 milliseconds, which is practically instant.
It's a 2.5-inch SATAII drive--currently the most popular interface--and is compatible with most notebook computers or any other devices that use this storage standard.
Transcend's new SSD also has integrated Error Correction Code technology, mostly found in memory for servers, that helps ensure accurate data transfer and built-in wear leveling technology designed to give the drive long storage lifespan and reliability.
The drive will be available later next week with capacities ranging from 8GB to 192GB. It also comes in an IDE version. All drives come with a two-year warranty. The 192GB SATAII version is estimated to cost $454.
You need a 3G phone like the AT&T Tilt or the Apple iPhone 3G to take advantage of a 3G network.
(Credit: Dong Ngo/CNET Networks)So the iPhone 3G is coming out tomorrow. Are you ready? OK, that's more of a rhetorical question that those who've been lining up in front of Apple and AT&T stores in NYC and San Francisco would call me crazy just for asking. (Though, in fact, it's they who are crazy). The real question is if AT&T is ready. And it looks like it is.
It's only fitting that AT&T announced today that it offers the nation's fastest 3G network, by a significant margin. The claim was made based on a variety of tests conducted by leading third-party researchers, who tested the throughput speed and overall performance by downloading and using multiple applications and files at a time.
The company also announced that it has started doubling the capacity of its 3G markets and that by the end of the year, about half of all its cell sites will receive additional 3G capacity. This will bring the total 3G coverage area to 350 major U.S. cities and metropolitan areas, up from 296 currently. In addition, AT&T also has the largest global coverage, with roaming available in more than 200 countries, with 60 of them being 3G roaming.
Those impressive announcements above are the direct result of the investment AT&T made in network improvements and upgrades between 2005 and 2008 that totaled up to $20 billion. Much of this network investment has gone to building out the 3G broadband data network and deploying additional 3G coverage using the 850 MHz spectrum, which is now available due to the recent sunset of its older TDMA network. This spectrum extends farther and better covers the interior of buildings.
The biggest benefit of the 3G network is, of course, the high-speed data connection; however, it also allows for simultaneous voice and data activities. For example, you can instant message and talk to the same person at the same time with your 3G phone. Now that's really crazy.

Japan's train industry may have made headlines in recent months for its hybrid fuel experiments, but its true historical claim has been the high-speed performance that made its "bullet trains" famous decades ago with speeds up to 186 mph.
The country is continuing that tradition today with the "N700 Series Shinkansen" line. A prototype of the train, which was just unveiled publicly, runs at about the same speeds as its predecessors but has one major difference: It tilts. The one-degree difference allows a 16-car train to maintain speeds of 167 mph even as it makes its way around curves, according to Fareastgizmos.
With a ride like that, who needs a $300,000 simulator?
