History and Theory of the Spiral Pump In some instances, records of preindustrial technology can be a source of concepts which can be updated with modern materials and modified to be utilized in today's technology transfer efforts. Wirtz invented the spiral pump to provide water for a dye works just outside of Zurich. The Wirtz spiral pump was constructed so the end of the outside pipe coil opened into a scoop.

Amazing life hacks (Infographic) Immersive Cocoon // Step Into The Future. Directed & 3D CG by Oliver Zeller, Video Courtesy of I-Cocoon The world of interfaces continues to evolve and surprise us. We still think of it as something we can hold, fold and place in our bag to carry anywhere. What if you can be part of an intuitive and holistic experience where your interface is not reduced to a mouse-click or a two dimensional tablet screen. Welcome to the Immersive Cocoon, a surround display dome with sophisticated motion sensor technology that inspired the technology depicted in 'Minority Report'. Now your body becomes the interface, as you are enveloped and your body movement becomes part of this digital environment to make our everyday lives more enjoyable, at least that is what this conceptual project tries to explore.

FreedomPop is expanding its low-cost coverage in a big way with Sprint's 3G network. FreedomPop, the company that is basically giving you online access for free, is expanding its coverage dramatically with the addition of 3G service via Sprint's nationwide network.
The company is now accepting orders for its first 3G/4G hotspot, the FreedomPop Overdrive Pro. What is FreedomPop, exactly? Until now, FreedomPop was a wireless service provider that offered either free or inexpensive plans on Clearwire's 4G WiMAX network, with the ability to earn additional free data by signing up for offers and inviting friends. Those plans remain in effect, but FreedomPop is expanding its coverage roughly 65 percent by offering 3G support on Sprint. "The biggest criticism with our service to date has been the coverage gaps in certain parts of the country," said Stephen Stokols, FreedomPop's CEO.
The Overdrive Pro costs $39.99. We'll be getting our hands on an Overdrive Pro from FreedomPop shortly. Westminster Butt Face Towel - Model# 0076: Home & Kitchen. Mycestro 3D Mouse Ring. Controlling objects through abracadabra gestures seems to be a hot trend right now. So can someone please make me a Mycestro 3D Mouse ring or MYO Armband that, in addition to manipulating my PC, will also abracadabra my dog's shit from the ground to the bag while I go all Houdini on it from a safe distance away? Nick Mastandrea, Mycestro godfather, how about it? Mastandrea conceived his idea for a mouse worn on the index finger while flying with a passenger who struggled to cram his laptop on the tray table and use its traditional mouse in the limited space. With Mycestro, simple hand movements remotely deliver all of the same mouse commands as a grounded device. And here, there's no little ball to get gunked up and jammed, or touchpad to freak out when fingers get slightly sweaty, or greasy from doubling up on computing and bacon eating.
Mycestro tracks hand motion in 3D space. Mycestro's range reaches up to 30 feet.
