Putting VPX and Open VPX to Work

Before the advent of OpenVPX, designers of embedded systems took advantage of the extreme connectivity offered by VPX (VITA 46), but were faced with a virtually unlimited number of possible implementations. Specific choices for the control and data channel assignments for each slot, the backplane connectivity, and serial fabrics were often made somewhat arbitrarily to suit the particular needs of the current system. Although following the general framework of VITA 46, each system tended to be so unique, that the boards and backplanes designed for one system were seldom usable in other systems, even from the same vendor.

Is nine hours a day too much "screen time?"

This week's Question: A recent study from Common Sense Media found that parents spend more than nine hours (9:22) a day with screen media, with the vast majority of that time being spent with personal screen media (7:43) and only a little more than 90 minutes devoted to work screen media. Most parents surveyed (78 percent) believe they are good media-use role models for their kids.What do you think? Is nine hours a day too much "screen time?"

CoaXPress Frame Grabber

Responding to the need to create a cost-effective, high-speed interface to fully leverage CXP cameras, BitFlow (Woburn, MA) has introduced the Aon-CXP single link CoaXPress frame grabber. The Aon is powerful enough to support camera speeds up to 6.25 Gigabits/second, which is almost twice as fast as USB3 and over six times the speed of current offerings of GigE Vision. While capturing video at those speeds, it is simultaneously sending control commands, triggers and up to 13 W of power over a single piece of 75 Ohm coaxial cable.To learn more, click here

Novel Computer Chips Could Bridge Gap Between Computation and Storage

Software written by Jing Li, right, and her students — including Jialiang Zhang, left —allows programmers to directly use existing coding languages with the new Liquid Silicon chips. (Credit: Stephanie Precourt/UW–Madison College of Engineering) Computer chips in development at the University of Wisconsin–Madison could make future computers more efficient and powerful by combining tasks usually kept separate by design. Jing Li, an assistant professor of electrical and computer engineering at UW–Madison, is creating computer chips that can be configured to perform complex calculations and store massive amounts of information within the same integrated unit — and communicate efficiently with other chips. She calls them “liquid silicon.”

Yoon, Korea University) A new, ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University. The film is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.
