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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
