Consisting of an encoder or potentiometer and a wire that pays off a drum, a cable extension transducer provides inexpensive measuring over long distances because its wire needs no guidance to follow a straight line-only an attachment at the working end. Also called draw wire sensors, string pots, even yo-yo sensors, the devices can be installed without much fussing over alignments. They are built to withstand extreme environments, such as paper mills, or can be furnished as instrument grade styles that are at home in a lab.
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.
