The Adaptive Cruise Control (ACC) system automatically adjusts a vehicle's speed to maintain a constant headway between vehicles. A pre-set cruising speed is applied through the automatic adjustment of the throttle by downshifting and/or actuating "feather" braking. A radar headway sensor, hidden behind the grille, detects obstacles ahead and enables the vehicle to travel at a set speed or adapt to the speed of the vehicle in front. An on-board microcomputer processes the radar information and converts the electronic instructions into engine speed or brake pressure.
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.
