 | ID/OD Retaining Ring Lock
Spirolox Retaining Rings can operate in an internal and external groove at the same time. Install the ring in one groove and then compress the ring with the mating component into the second groove. When the grooves meet, the ring snaps into place creating a low-cost, hidden, high-strength, tamper-proof rotating joint. Over 6,000 rings are stocked from 1/4" to 16" diameters in carbon and stainless steel, customs up to 120".

 | New 10-mm Motor Doubles Output Torque
MICROMO launches the next generation of small DC motors: the 1024 SR series from FAULHABER. This coreless micro motor features a 10-mm diameter and offers high performance with small dimensions and low weight, making it ideal for high-demand medical applications and portable devices. Combined with a gearhead, its output torque can achieve 300 mNm, twice that of similar products. A superior torque/speed ratio means the motor can handle varying loads at reduced speed variations.

| | Feature articles | No GPS? U.S. military listens to VLF radio signals to find way home
 The Defense Advanced Research Projects Agency (DARPA) is working to develop a back-up system to be used by service members in the event that access to the Global Positioning System, or GPS, is denied to them by adversaries. "We're focusing on naval surface and aviation ... and it's very applicable to Army helicopters," said Lin Haas, DARPA's Strategic Technology Office.

 | Go for the gold: Achieve high-frequency interconnection with bellows contacts
Servometer electrodeposited gold-plated (ASTM-N-488) bellows contacts create a reliable solution for electrical connections with less signal loss versus competing technologies. Servometer bellows contacts are a reliable alternative to spring-loaded type test pins in high-frequency test applications, and are designed to provide lifetime spring and force repeatability, in diameters as small as 0.020 in.

 | Robotics: Modular kit for low-cost automation
The Robolink D modular robotic kit from igus allows users to assemble custom robotic systems for a range of applications. Separate joints, which are motor-driven directly on the axis, are available in a range of installation sizes. A new, 6-axis arm with strain wave gearing (in two installation sizes) is also available, along with universal gripper adaptors. The gearing, available as an individual component or with integrated NEMA motor, consists of an outer ring gear and flexible, wear-resistant inner ring gear made from self-lubricating, wear-resistant iglide plastic. This solution offers minimal backlash and ensures a precise adjustment with incredible smoothness.

 | Can your rooftop handle solar panels? Sandia tests say 'probably so'
Most U.S. rooftops in good repair can take the weight of solar photovoltaic (PV) systems. That's the conclusion of a three-year study by a research team led by Sandia National Laboratories. "There is a misperception in the building industry that existing residential rooftops lack the strength to carry the weight load of rooftop solar photovoltaic installations," said Sandia structural engineer Steve Dwyer. "Most existing well-built wooden rooftops can support PV system loads."
