MINISUB INSPECTOR
VideoRay 2002 Remotely Operated Vehicle. Three Pittman(R) LO-COG(R) brush dc motors power this 8-lb camera-toting minisub geared for commercial operations and recreational use. Two of the direct-drive motors are in side-mounted tubes for horizontal thrust. The other motor in the hull center thrusts vertically. According to Marcus Kolb, director of R&D, direct drive reduced system complexity, improved reliability and lifetime, and lowered costs. He notes a challenge was the motors' polished shafts where the propellers are attached. The shafts must be smooth and hard, so VideoRay machines them using a proprietary process. These are supplied to PennEngineering for its Pittman motors and the OEM integrates the motors and seals into the shaft housings.

PROJECTING WELL
3M Bravo Projector. Seeing that its customers wanted to look good in all aspects during presentations, 3M's developers coordinated a rapid 10-month design effort from Austin to Italy (as well as Japan, China, and Germany) resulting in a stylish as well as technically advanced projector. Pininfarina, noted for its Ferrari designs, brought style to the team. An ease-of-use interface accesses features via file menus and allows users to optimize projection for the format involved-from PowerPoint to cinema (with its demands for true colors and contrast). A clip-in base has swivel, up/down, and side-to-side degrees of freedom for quick image position and shape adjustment on the screen. Mid-year will see a home-market model with 16 x 9 aspect ratio imaging for television. Wall Display Unit Manager: John Griffiths, [email protected]http://rbi.ims.ca/3847-542
BE SEATED
Dahti Technologies Herman Miller Mirra(TM) Chair. Use of DSM Engineering Plastics' Arnitel(R) EM400 thermoplastic copolyester-based elastomer (TPE-E) to encapsulate the elastomeric-mesh seat carrier was critical to this chair's design. Molded into a bead with holes around the edge of the carrier, the Arnitel's stiffness and elongation contributed to the manufacturability and functionality of a mechanical "zipper," which folds the holes onto teeth around the plastic chair frame. The Arnitel combines strength and processing characteristics of engineering plastics with the performance of thermoset elastomers. As a thermoplastic, it does not require vulcanization to optimize properties, saving part cost. Compared to other elastomers, it has relatively consistent performance over its operating temperature range. DSM Business Development Manager: Doug Bosch, [email protected]http://rbi.ims.ca/3847-543
