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.

Edge-Connect SBC

ADL Embedded Solutions Inc. (San Diego, CA) has announced its compact ADLE3800SEC SBC with Edge-Connect. This ultra-compact 75mm x 75mm form factor is a full-featured, standalone SBC for rugged, embedded applications. The ADLE3800SEC is ideal for rugged, extended temperature intelligent systems with stringent size, weight, and power (SWAP) requirements. It boasts a wide thermal junction temperature (Tj) range (-40°C to +85°C), wide input voltage (20-30 VDC), DisplayPort, USB2.0, USB3.0 and two GLAN ports with support for DirectX 11, Open GL 4.0, and full HD video playback. The Edge-Connect architecture allows for added I/O expansion and connectors in a variety of baseboard/breakout board configurations (flat, vertical, odd-shapes, etc.).

Novel Computer Chips Could Bridge Gap Between Computation and Storage

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.”

Rugged Train Control System

MEN Micro’s (Blue Bell, PA) MA50C is a modular system for safe train control that complies with AAR (Association of American Railroads) standards. The new controller unit features a mechanical design that meets AAR S-590 as well as an AAR S-9401-compliant enclosure that houses a safe CPU, real time Ethernet card, power supply and shelf controller. An MCU (modular concept unit) design efficiently hosts a single tower of up to six standard 3U CompactPCI boards. User-specific functions, such as safe digital I/O, MVB (multifunction vehicle bus) and serial I/O, are accommodated by incorporating different boards into the system’s slots.

For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometer-gate transistors now on the market. But some laws are made to be broken, or at least challenged.

T-rays Will “Speed Up” Computer Memory By a Factor of 1,000

The figure shows the spin and lattice structure of thulium orthoferrite (TmFeO₃) on the left and the T-ray-induced transitions between the energy levels of thulium ions (Tm³⁺), which trigger coherent spin dynamics (memory switching), on the right.

Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer performance. They propose the use of so-called T-waves – or terahertz radiation – as a means of resetting computer memory cells. This process is several thousand times faster than magnetic-field-induced switching.

An Operationally Based Vision Assessment Simulator for Domes

Applications include remote visualization, flight simulation, virtual environments, and planetariums.

Ames Research Center, Moffett Field, California

The work described here is part of the U.S. Air Force-sponsored Operational Based Vision Assessment (OBVA) program that has been tasked with developing a high-fidelity flight simulation laboratory to determine the relationship between human vision and performance in simulated operationally relevant tasks. The OBVA simulator was designed and built to provide the Air Force School of Aerospace Medicine (USAFSAM) with a scientific testing laboratory to study human vision and testing standards.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.
