Satellite Reaction Wheel Torque Reaction wheels provide an efficient solution for satellite attitude control. To develop this control system, a torque sensor is mounted to a motor and flywheel pair. As the motor spins the flywheel, the torque sensor captures the torque generated over time. These measurements are then used to design and tune an efficient control system. Learn about torque sensor setup in this application.

Largest optical telescope in the world driven by 2,000+ PI actuators High atop the Cerro Armazones mountain in the harsh but extremely dry environment of the Chilean Atacama Desert, more than 2,000 custom hybrid actuators will adjust 798 quarter-ton segments in the primary mirror of the European Extremely Large Telescope (E-ELT). As a leader in precision motion control solutions, PI (Physik Instrumente) designed a new type of actuator to meet the extreme requirements of this amazing application.

Researchers integrate high-speed data and wireless power transfer Researchers from North Carolina State University have developed a system that can simultaneously deliver watts of power and transmit data at rates high enough to stream video over the same wireless connection. By integrating power and high-speed data, a true single "wireless" connection can be achieved.

Wheels: Mercedes brings yacht style to the Maybach 6 Cabriolet concept If Thurston Howell III dreamed of the far-distant future while shipwrecked on "Gilligan's Island," he probably imagined tooling around the mainland with Lovey in something like the yacht-inspired Vision Mercedes-Maybach 6 Cabriolet concept. Recently displayed at Monterey Car Week in California, the 750-hp (550-kW) electric hard-top convertible is luxurious, pretentious, exaggerated, and a real head turner -- but it's full of clever and impressive design details too.

Engineer's Toolbox: Why direct drive technology? Direct drive technology has been around for over 40 years, but there still is a lack of understanding of it by many machine builders. Even those who are familiar with it may not have a desire to adopt the technology, considering it to be too high-end when compared to a gearbox drive solution that has been "good enough" for many years. But eventually the benefits of a more advanced technology may become too difficult to ignore. By Brian Zlotorzycki, Product Specialist, ETEL Motors

Carbon composite bellows springs for lightweighting and more The Carbon Composite Bellows Spring (CCBS) from MW Industries is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace conventional coil springs or metallic Belleville disc springs. It offers value through unique dynamic characteristics and unparalleled in-the-field design flexibility. A functional spring is made from several individual elements, paired in sets and joined to make a stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, outdoor recreation, general industry, and high-performance activities.

Multi-axis robotic controller Aerotech's HEX RC is a 6-axis motion controller ideal for controlling robotic systems like hexapods. It is 4U rack-mountable and compatible with the Automation 3200 (A3200) motion platform. A high-performance processor provides the intense computing power needed to run up to 32 axes, perform complex, synchronized motion trajectories, manipulate I/O, and collect data at high speeds. This unit features 6 axes of drives capable of controlling any combination of brush, brushless, or stepper motors (both current loop and servo loop closures). An optional 6-axis jog pendant permits easy, manual control of the positioning system.

Optimize your product manufacturing cost analysis Boothroyd Dewhurst, developer of internationally recognized Design for Manufacture and Assembly (DFMA) software, has released DFM Concurrent Costing, Version 3.0. Deployed as a cost-analysis tool for engineering and procurement teams, the latest software allows manufacturers to move beyond "price" models, based largely on past bids, to industrial cost models grounded in scientific test data and studies. The result is a highly reliable "should cost" view of the product that offers insight into hidden cost drivers and ways to optimize both design and production.

WWII Engineering: The saga of the bird-brained bombers During World War II, the National Institute of Standards and Technology (NIST) was among those working intensely to develop guided weapons to help the Allies win the war. But before the advent of satellites and GPS, laser targeting, or even radar, how would one guide a bomb? Why, trained pigeons, of course.

Wings: Industry sends NASA X-Plane ideas flying It won't be long before NASA's aeronautical innovators will have a tough decision to make. While moving ahead with plans to field a new "quiet" supersonic X-plane during the next few years, agency researchers also are developing a plan for commercial airliners that are quieter, burn less fuel, and release fewer emissions. The big question is, what will a new subsonic X-plane look like? Five concepts are in the works.
