When you turn Ojarumaru Man on, he says something (in Japanese) about the firefly on his hat and waves his tiny, 9-gram plastic arm up and down through 60 degrees of motion. Because of O-Man's peaceful, Zen-like demeanor, engineers wanted a completely silent method of actuation that would be cost-competitive with an inexpensive, single-speed motor. (In fact, the original design called for a traditional electromagnetic motor, but engineers rejected it because it was too noisy.) In this simple application, engineers mounted Oman's arm to the output shaft of a Nano-Muscle RS-70-CE actuator, which runs off of two AA batteries and uses shape memory alloys (SMAs) as the motive force. SMAs undergo a solid-state phase change when their temperature drops below a specific transition point, providing constant power output across the entire stroke length and a force-to-weight ratio on the order of 15 kgf/m2.
Nanomuscle offers a new commercial development kit for its RS-70-CE actuator for $199.95 or toy development kit for $179.95. For details, go to http://rbi.ims.ca/3849-563
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
While people may talk about the procurement process, the procurement discipline actually encompasses a number of different processes. They include spend analysis, supplier relationship management, and contract management, just to name a few.
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.
