Most travelers have heard the advice: Don't drink the water when traveling overseas. But, what can you do when the spirits run out? Buy bottled water or a filter. The challenge arises when deciding which filter or bottled water to choose.
This device processes approximately 16 ounces of water in about 2.5 minutes. Simply turn the unit on and fill the top reservoir with water. While flowing through a silver-activated carbon filter and into the base reservoir, the water charge receives a 187,000 (mu)W-sec/cm(super2) UV dose.
A power converter or an external battery pack (holding eight C-size batteries) provides power to the high-intensity lamp. One battery pack will process about 75 oz/day for two weeks before the batteries need replacing. Testing for Giardia and Cryptosporidium are still in the works.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
