Northern Magnetics has unveiled a 24-axis linear motor driven positioning stage that provides independent motion along each of the 24 axes. The base measures 72 inches long and contains an EPS positioning stage with non-cogging, ironless core, medium-force, brushless linear motor with 12 independent coil assemblies. Each assembly consists of a 1.5-inch stroke, bellows, encoder, special bearings, and limit switches. Mounted to each of these X-axis slides is a single Y-axis special bearing positioning stage with a non-cogging medium force brushless linear motor capable of 3.5-inch stroke, encoder, and limit switches. A total of four bearings support the payload, moving coil, and encoder head. Northern Magnetics, Product Code 4214.
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.
