Siemens Automotive has under development a second-generation, common rail system for high-pressure diesel fuel injections. The technology has as its goal the reduction of nitrous oxide (NOx) emissions and the noisy operation of diesels. High-pressure fuel injection resulting from the common rail (CR) technology is said to be a key to better diesel spray atomization, improved fuel/air mixing, and more efficient combustion of fuel in engine cylinders. The system incorporates piezohydraulic valve technology to precisely regulate the high-pressure injection of the fuel. The modular design incorporates the rail, valves, fuel injectors, sensors, and actuators into a single package that, according to Klaus Eggers, Siemens project leader for diesel systems, "will provide design flexibility and cost savings." Siemens engineers say piezohydraulic valves react up to four times faster than solenoids currently used, responding to voltage pulses within 0.1 msec. FAX (248) 253-2998.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isn’t a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
