Ostensibly geared toward children age 10 and over, the new Mindstorms will also appeal to professional hackers. The sets will use open source software, Linux, for the first time, and controller apps are integrated for tablets and mobile phones.
When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals: a technique known as electronic attack (EA) or jamming. Conversely, electronic protection technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets. A research team is now developing a new generation of advanced radio frequency jammer technology.
Researchers in Israel have developed a simple magnetization progress that depends on electron spin to eliminate the need for permanent magnets in memory devices. The new technique, called magnetless spin memory (MSM), drives a current through chiral material and selectively transfers electrons to magnetize nanomagnetic layers or nanoparticles.

Today’s digital designs are evolving in a variety of ways, prompting new approaches to design, simulation, measurement and debug. One change is the use of more serial buses. Another is the use of system-on-a-chip (SOC) integrated circuits or advanced field-programmable gate arrays with SOC capability. Despite this evolution, there's still a role for classic parallel buses in many designs and the need to measure those buses.
Over the past decade, significant changes have been underway among users of electronic test and measurement instrumentation. For example, electronics companies’ R&D staffs have shrunk, and engineers report they are under pressure to do more with fewer resources than in the past. At the same time, there are fewer engineers dedicated to test with in-depth test and measurement training and background.
The space program in the mid-20th century accelerated the switch from analog to digital systems for high-speed data acquisition and monitoring.
