This motion control card is the first to communicate and supply power at the same time using an Ethernet bus, working at distances up to several thousand yards. It has an integrated Web server, using Ethernet protocol to control 10-48V dc brush motors. It can work with protocols like http and TCP-IP that are already embedded in most major computer operating systems, plus it runs from an Ethernet cable at powers up to 15W (card + motor), using the latest IEEE 802.3af standards. An external power supply allows the card to work at up to 70W continuous and 140W max. Its embedded RISC processor has a 4-quadrant, 32-bit RISC PID regulator, refreshing power regulation of to 4KHz with a sampling rate of 20-2,000Hz, so it can control brushed dc motors by position and speed, and position with a trapezoidal speed profile. They come in a variety of available modes.
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.
