A newly patented invention avoids the cumbersome procedure of "fine tuning" electric motors. At NASA's Marshall Space Flight Center, Ann M. Casper designed a brushless dc motor that dynamically times the commutation between the rotor and stator--without disassembling its housing. She put Hall-effect sensors on the commutation board to provide feedback on the rotor position. A tool inserted into the endcap, while the motor runs, "tunes" the motor for maximum operating efficiency. invention received United States Patent 5654599.
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
