MR318 is the world's first commercially-available rotary
position sensor which can operate with complete "transparency" in
extreme electromagnetic fields such as MRI machines. An enabler for functional-MRI (fMRI)
research, the encoder allows medical researchers to develop MRI-compatible test
apparatus where measuring position, angle or speed is required. Doctors can monitor brain activity of stroke
and other impaired patients while pedaling, observing how brain and body adjust
to therapy and rehabilitation techniques.
Also enables development of phantom devices for MRI calibration and
teaching. Non-medical applications
include motion control where EMC "transparency" is required, including
radar scanners, anechoic chambers and DEW weapons. Prior to commercial availability of the MR318
encoder, engineers had no commercial solution for measuring continuous position
within an MRI chamber. Motors or
actuators could be hydraulic or pneumatic but no commercial position sensor
existed. A homemade fiber optic
proximity/limit switch was the best solution - but this was awkward to design,
package and only provided position information at discrete points. The company says the MR318 encoder is the world's
first and only commercially available, non-metallic rotary position sensor
which operates "transparently" in extreme electromagnetic
fields. There is no comparable product
on the market.
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.
