Linear Stage

Bell-Everman (Goleta, CA) offers the SLS Light sealed linear stage that keeps contamination such as manufacturing debris, particulate, or liquid contaminants outside of the stage housing. The stage measures 80 x 120 mm, and has maximum dynamic payloads of 15 kg for the direct drive linear motor version and 30 kg for the ball screw version. Both sizes deliver a proprietary linear lip seal design that integrates with the stage’s anodized aluminum housing. The seal is made from a ruggedized polyurethane elastomer and resists chemicals, temperature extremes, and mechanical wear. The seal can be replaced without disassembling the stage or removing payload. Applications include any application where contaminants can threaten the smooth operation of a linear actuator including laser machining, welding, semiconductor, and machining.

Piezo Drive

The Ensemble QDe™ desktop nanopositioning piezo drive from Aerotech (Pittsburgh, PA) was designed for seamless use with the Ensemble family of drives and controllers. The QDe connects to any Ensemble controller network, enabling coordinated motion between piezo stages and servo axes. The drive is suitable for single- or multi-axis applications such as point-to-point motion, linear and circular interpolation, multi-axis error correction, and autofocusing. High-speed interrupts and data logging capabilities provide a real-time link to external systems.

Products of Tomorrow: October 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Modern CMOS Cameras as Replacements for CCD Cameras

Many users of CCD sensors are asking about the advantages of the latest CMOS sensors, particularly if they have been using CCD-based cameras. The two sensor technologies, a comparison of the new CMOS sensors and existing CCD sensors, and tips for when it makes sense to select a new camera with CMOS sensors are provided in this article, as well as what to expect after integration.

Custom System Rides the Rails at NASA Radar Range

Custom linear guide rails NB Corporation of America Hanover Park, IL 1-800-521-2045 www.nbcorporation.com ADC USA, Inc. (Ithaca, NY) develops and supplies high-precision motion systems and instruments for large government laboratories and corporations around the world. ADC was contracted by NASA’s Langley Research Center (Hampton, VA) to design, build, and install the major components for a 40 × 40 × 40-foot indoor radar range. NASA’s goal was to refurbish and upgrade their old indoor radar range. They want to clear out what they had and replace it with newer, better-designed equipment. The goal was to put multiple targets inside the radar range without having to get a forklift to bring them in and out – not only things such as airplanes, but anything that is detected by radar.

Underwater Adhesives Retrofit Pipelines with Advanced Sensors

NASA-developed sensors and adhesion methods equip pipelines and tension legs that hold offshore platforms upright for safety monitoring. By the time the gas you fill your car with hits the engine, it’s been through quite a journey. An oil platform in the Gulf of Mexico, for example, might need to be built over water with a depth of 10,000 feet. Long pipelines under high pressures face a multitude of dangers. Some are structural, such as natural vibrations generated by ocean currents and waves that bend the pipes back and forth — a phenomenon known as vortex-induced vibration, which is similar to the sway of a car antenna wire when driving on the highway. Other risks lie inside the pipe, where the right combination of pressure and temperature causes the hydrates in the oil to precipitate, forming a dirty, snowball-like mass that quickly grows.

Editor's Choice: October 2015

A habitat was developed that allows water recycling, air treatment, thermal control, and solids treatment and recycling to be performed in the walls of a radiation-shielding water wall. This game-changing method for mass reuse provides radiation protection, building materials, and structural elements for a habitat. The method can also be used in wastewater treatment plants, and removes the air, water, and waste treatment hardware from the usable habitat. Find out more HERE.
