Volvo doesn't trust the air we breathe, at least not that of many polluted city centers. Instead, it has come out with the Volvo Ambient Air Cleaner (VAAC)—currently used in Volvo's Versatility Concept Car (VCC)—which filters the surrounding air of hydrocarbons and nitrogen oxides. Among the benefits: it neutralizes the equivalent of up to three cars' exhaust emissions, and its sensor activates the fan in response to pollution detection. Solar cells power the VAAC when the car is parked.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
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.
