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.

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.

Application Note: Auditing robotic prosthetics
With advancements in prosthetics allowing fine motor control driven by a patient’s nervous systems, the use of miniature load cells placed at grip points helps observe a wide variety of operating conditions the patient requires from their prosthetic every day. Sensor specialist FUTEK runs through the basic setup.

Wings: Graphene de-icer coating does double duty
Rice University scientists have advanced their graphene-based de-icer to serve a dual purpose. The new material still melts ice from wings and wires when conditions get too cold. But if the air is above 7 deg F, ice won’t form at all.

Designing in the cool factor -- Custom Russian choppers use in-house CNC

How sweet it is when you've got the right tools. For Vladislav Belyakov, the CEO of BOX39 in St. Petersburg, Russia, the tools that often make all the difference are his in-house design and milling capabilities. Belyakov pushes design and construction edges from fantasy land into the real world by customizing a bike into something recognizably cool, like an amazing cartoon that you can ride.

Mike Likes: ABCs of gears and more
KHK USA takes you on a journey through the history and applications of gears in two information-packed free volumes called "The ABCs of Gears." Part A is aimed at beginners, while part B moves on to intermediate fare, such as types of gears and tooth forms, heat treatment, surface treatment, production methods, etc. Another mid-level text called "Introduction to Gears" and an in-depth "Gear Technical Reference" are also available, chock full of materials information and calculation examples and tables. Best of all, there is no registration for any of these valuable no-cost PDF resources.

Researches hunt down source of annoying golf club clang

In 2007, a new type of golf club hit the market. The distribution of mass in the club head made it less likely to twist, making an off-center hit less likely to send the ball veering off course. It did have one drawback, though: a loud noise when it struck the ball, "like a cookie tray hitting the top of a car."

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.

Auto: Lean-and-mean CANopen motor controllers
The ability to maximize battery life and extend vehicle operations, essentially running “lean and mean,” is the key to keeping a vehicle operating at peak performance. The DVC series motor controllers from Advanced Motion Controls are digital four-quadrant servo drives purpose-designed and built to operate today's modern mobile electric vehicular platforms. Providing high power from battery supplies, the DVC series features a compact design, IP65 construction, and multiple operating modes for controlling either permanent-magnet brushed or brushless motors in applications such as traction/propulsion, steering, and lifting.

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.”
