Measurement Systems Aid NASA in Study of Space Station Solar Array Anomaly

Surface and roundness measurement systems Taylor Hobson West Chicago, IL 630-621-3099 www.taylor-hobson.com NASA’s Marshall Space Flight Center in Alabama is using the Form Talysurf PGI 1230 Surface Measurement and the Talyrond 295 Roundness/Cylindricity Measurement Systems from Taylor Hobson to perform critical surface analysis of a damaged bearing assembly from the International Space Station (ISS). The results are expected to help NASA experts determine the cause of the damage to the Solar Alpha Rotary Joint (SARJ), a 10-footdiameter ring that allows the station’s solar panel array to rotate and track the Sun.

Yaskawa Controllers Help Echo Hill Upgrade Grinding Operation

Echo Hill Automation Inc., a Beamsville, Ontario, Canada company founded by mechanical engineers and brothers Dan and Harry Schellenberg, has grown from a small two-man operation to a successful manufacturer of centerless grinding automation, with the help of servomotors and controllers from Yaskawa Electric of Waukegan, IL. Centerless grinding automation is used for high production grinding, where tight tolerances and good part roundness has to be achieved.

Renishaw Encoder Improves Positional Accuracy for CNC Optical Maker

When a leading manufacturer of CNC optical manufacturing technology needed ultra-accurate and stable positioning for a new system to measure conformal optics, it turned to ABTech Manufacturing Inc., specialists of custom- made ultra-precision air bearings and motion systems. In order to meet tighter customer specifications for positioning resolution, ABTech found the solution in high-resolution linear and rotary optical encoders from Renishaw. ABTech created a five-axis optical measurement platform featuring three of its linear air bearings, two of its rotary air bearings, and Renishaw’s ultra-high accuracy SiGNUM(TM) series linear and rotary encoders.

Using Vision Sensors to Eliminate Manufacturing Defects

Supplying parts to the world’s leading automotive companies leaves no room for error. That’s why Miniature Precision Components Inc. (MPC) uses three vision sensors to error-proof the automated assembly of oil-caps at its Prairie du Chien, WI facility. With 41 molding machines ranging in size from 25 to 550 tons, this 100,000 square-foot facility employs about 450 people. MPC’s four manufacturing plants generate approximately $167 million per year supplying the automotive and commercial industries with high-quality injection-molded parts and assemblies such as PCV valves, thermostat housings, and quick-connect ports for emission control systems.

Connectors Provide Signal Reliability for Mars Science Laboratory

Compact PCI (cPCI) ConnectorsHypertronics CorporationHudson, MA978-568-0451www.hypertronics.com Hypertronics’ space-grade Compact PCI (cPCI) connectors were selected by NASA’s Jet Propulsion Laboratory (JPL) for use on the Mars Science Laboratory (MSL), which is scheduled to launch in 2009. Incorporating the Hypertac® “Basket of Wires” contact technology, the connectors will be instrumental in all phases of the mission including lift-off, navigation, entry, descent, landing, roaming, and geological survey. Behind these embedded systems are single-board computers connected together through common back planes that handle all control functions and analysis for the MSL rover. All systems and components must exceed the long and difficult journey to Mars, as well as the extreme surface operation of one Martian year, equal to two Earth years.

Wireless Video Surveillance System Secures Aircraft

AgileMesh/Firetide surveillance systemAgileMeshDallas, TX972-231-2122www.agilemesh.comNASA Dryden Flight Research Center now protects several of its highly specialized research aircraft at its satellite facility with a wireless video surveillance system. The system is a product of AgileMesh, a provider of rapidly deployable video surveillance, and Firetide, a developer of wireless mesh and access networks. The AgileMesh/Firetide system secures a recently leased hangar that houses NASA’s SOFIA (Stratospheric Observatory for Infrared Astronomy) and DC- 8 Airborne Laboratory aircraft, both of which are unique to the nation.The rapidly deployable, solar-powered, and high-resolution wireless system transmits evidence-grade video from the perimeter of the hangar to the on-site security operations center. The video is monitored in real time, allowing personnel patrolling the perimeter to communicate with the operations center and respond to incidents within seconds. Using embedded Firetide mesh technology, the AgileMesh units wirelessly transmit video signals to a head-end node located in the security operations center. The video is stored for 30 days for incident review and investigation. The AgileMesh units were secured to the ground using 20- gallon water containers as anchors, since winds can reach 60 miles per hour in the high desert. The research center is currently deploying a fixed video surveillance system in and around the hangar, and once that system is in place, the AgileMesh units will be used for securing crash scene investigations and during special events such as nearby air shows.
