Tech Needs of the Week

A coating that is hard and has a high modulus of elasticity is needed for application to polyvinyl alcohol (PVA) optical films. Excellent coating adhesion and optical transparency are mandatory. The coating must withstand a force greater than 13,000 MpA, and offer a pencil hardness of B or over.To respond to this Tech Need click here.

Current Attractions

Developed at NASA’s Marshall Space Flight Center (Huntsville, AL), a micro-commanding rotational-position-control system offers the advantage of less mechanical complexity, susceptibility to mechanical resonances, power demand, bulk, weight, and lower cost, relative to prior rotational-position-control systems based on stepping motors and gear drives. This system includes a digital-signal-processor (DSP)-based electronic controller, plus a shaft-angle resolver and a servomotor mounted on the same shaft.
