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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
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.
