Strip away the interference that ultrasound scanners ordinarily pick up from muscle and skin and you have a better chance of saving not only images of the body's inner workings, but also a great deal of space, time, and money. Engineers at the University of Rochester (Rochester, NY) have devised a way to store such slimmed-down ultrasound scans. The patented technique junks the unneeded echoes from soft tissue and saves data only from the underlying organ, all the while whittling the size of a digitized ultrasound file image to one-twentieth of what's now required. "While existing JPEG and MPEG technologies work from the assumption that an image has a photographic origin, our technology recreates an image based on the assumption that it's working with data gathered through a pulse-echo system," explains Kevin Parker, professor of electrical engineering at Rochester. "It's a method of reconstructing images that's in step with the way ultrasound scanners collect data," and about 20 times faster. Phone (716) 275-4151.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
