Servomotor Couplings

The ServoClass coupling line from Zero-Max (Plymouth, MA) has been expanded with three new sizes to handle bore diameters from 0.875 to 1.378" and operating torque from 3.937 to 9,843 in. lb. The lightweight couplings incorporate Type 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. All have clamp-style hubs with corrosion-resistant socket head cap screws.

Conveyor System Valve

The Series VFD poppet valve for zero pressure accumulation conveyor systems from SMC Corp. of America (Indianapolis) provides a coefficient of volume flow (Cv) of 0.10 with an operating pressure range of 0 to 72 psi to handle large pressure drops found on long conveyor runs. It is designed to be incorporated with a conveyor system’s control logic and sensors, controlling the air pressure used for roller actuation and roller braking to make for smoother product transfer.

Ultra-High-Speed Thermography Reveals Hidden Features of Hot, Fast-Moving Objects

Most of us have seen still images or slow-motion video of fast-moving objects, such as a missile in flight or a humming bird flapping its wings. Both scenarios are possible with high-speed visible image cameras using ultra-short exposure times and triggered strobe lighting. Video images of this sort generally require high frame rates to ensure smooth playback.

Compact Vision for Development and Control of Unmanned Underwater Vehicles

The Mobile & Marine Robotics Research Centre (MMRRC) at the University of Limerick in Ireland created a generic solution for underwater development. During research cruises in February and June of 2005 with the RV Celtic Explorer, MMRRC researchers identified weak points of the overall system integration to address with a virtual underwater lab (VUL). The VUL is a mixed hardware/software tool designed to overcome identified problems; make overall system integration easier; and provide a framework for researchers to develop, implement, and test advanced control algorithms in a combined real-world/simulated environment.

Visualization Software Helps Assess Thin-Film Semiconductor Systems

As thin-film technology advances, it’s increasingly important to monitor the film’s characteristics. That’s because eliminating irregularities in thin films — used primarily to create computer chips — enhances their performance. k-Space Associates (kSA, Ann Arbor, MI) specializes in accurate, precise monitoring methods that allow physicists and engineers to create high-performance thin-film products and improve their research and development workflow.
