Digital gear: Sending ultra-wideband home
Car signs were the rage in the 1980s, with signs like "Baby on Board" reminding drivers to avoid tailgating. The trend is back with Roadmaster USA Corp.'s Scrolling Digital License Plate Frame, which displays scrolling messages on a car's license plate or back window. While those signs can be an eyesore, Tzero Technologies Inc. delivers high-definition entertainment through its chipset that wirelessly transfers HD (high-definition) video images from one high-definition device to another. Also enhancing the entertainment world is Shure Inc., with its new, albeit expensive, line of earphones, which offer improved sound and bass.
Roadmaster's car message
With warnings like "your lights aren't working," Roadmaster's LED message bar may save drivers from potential police busts. The Scrolling Digital License Plate Frame is an LED (light-emitting diode) bar that attaches to the license plate to deliver 99 preset messages including "Help me," "Slow down," or the "Baby on board." Users can customize messages, like a car's sale price and display it in non-scrolling mode if a car's on sale. It comes with a wireless remote to adjust an LED's speed and brightness. However, state and local regulations need to be checked before using the scrolling system when the car is in motion, according to the company. A similar system is available for a car's rear deck for $59 at retailers and car dealerships.
Shure's upgraded SE series of headphones
Shure's SE line of sound-isolating earphones is an upgrade over the company's famous E series brand, with new features, looks and more technology packed into it.
The $150 SE210 delivers deep audio through its built-in "hi-definition microspeaker" technology, which can also be found in the $250 SE310 model. The SE310 also has a "Tuned BassPort" technology that provides enhanced bass. The advanced $350 SE420 (with a tweeter and woofer) and the $450 SE530 (with a tweeter and dual woofers) have dedicated drivers for lower and higher sound frequencies to better define and deliver low-range, mid-range and high-end sound.
The company poured years of research and testing into these earphones, said Matt Engstrom, product manager of personal audio at Shure. Though the earphones resemble the E series earphones, the slightly smaller size of the SE210 and SE310 headsets also contribute to the better sound it delivers.

Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.
