 | Watch High-Speed Ultrasonic XY Motor Align!
This mini XY linear stage with piezo-ceramic motors combines sub-micron precision with excellent dynamics -- ideal for optics, medical design and photonics applications. In addition to the high speed up to 200 mm/sec, the low inertia (direct drive, no rotating parts) allows for a rapid start-stop behavior with settling times in the milliseconds. How can you use this XY stage?

 | High-tech Refractory Metal Fasteners for Extreme Conditions
Refractory metal fasteners (nuts, bolts and washers) are ideal for situations that involve high temperature, high voltage, magnetism, and harsh corrosive environments. All four metals offered -- tungsten, tantalum, niobium and molybdenum -- are chemically inert, have a melting point above 2400° C, high hardness at room temperature, relatively high density, and stability against creep deformation at very high temperatures. Sizes range from M3 to M6.

 | Robotics inspired by nature
Since walking is a natural process, it's obvious that the designs and control systems of many walking machines are based on natural examples. In the case of LAURON (Legged AUtonomous RObot Neural-controlled), inspiration came from the Indian stick insect. The robot was designed for use in settings that are too hazardous for people, or are difficult to access with wheeled or chain-powered systems.

 | Mazda celebrates: MX-5 Miata 30th Anniversary limited edition
There's a party going on at Mazda, and the Miata is the guest of honor -- the 2019 Mazda MX-5 Miata 30th Anniversary special edition, that is. Just debuted at the Chicago Auto Show this month, the forever-young two-seater is sportier than ever in its exclusive coat of Racing Orange exterior paint. And with a peppy 181-hp SKYACTIV-G 2.0L engine under the hood, drivers are sure to have a good time.

 | Appearance models impress clients, designers alike
Appearance models, the realistic prototypes produced with a combination of 3D printing, traditional manufacturing processes, and expert hand finishing, have a unique ability to dazzle. "Clients are amazed by the quality of the model, because they don't understand how it was made so quickly and realistically," says designer Robert Bronwasser. "It's some kind of magic for them." The "magic" of the model making comes from 3D Systems On Demand.

 | How a camera auto-focus lens uses a special spring
Ultrasonic motors are small motors, some measured in millimeters, that are being used in a variety of applications including the auto-focus feature on a camera lens, side mirrors, surgical equipment, and robots. Learn how a single-turn closed wave spring is used to maintain the necessary pressure against the motor stator in a camera, and why it is a better choice in this application over coil or washer-type springs.

 | Benefits of using military-grade adhesives in your applications
Some epoxy compounds successfully meet thermal stability testing standard ASTM D3850-12 per MIL-STD-883J Section 3.5.2 and 3.8.5 for military applications, however these systems can also be used across many other industries where thermal stability is an important requirement. Some common non-military applications that benefit from compounds that pass MIL-STD-883J include downhole oil equipment, lasers, satellite systems, electronics, power tools, and various automotive applications.

 | Desktop Metal launches 316L stainless steel for 3D printing
Desktop Metal, a 3D-printer maker, has just announced the launch of 316L stainless steel for the company's Studio System, the world's first and only office-friendly metal 3D-printing system. This machine is great for prototyping and low-volume production. A fully austenitic steel known for its corrosion resistance and excellent mechanical properties at extreme temperatures, 316L is well suited for applications in the most demanding industrial environments, including salt water in marine applications, caustic cleaners found in food processing environments, and chemicals in pharmaceutical manufacturing.

 | Vulcanized rubber spacer disks with a steel plate
The GN 438 rubber spacer disks from JW Winco provide a dampening and muffling function, protecting surfaces from damage. By stacking several spacer disks on each other, the spring rate of the package can be increased, which opens up new possibilities for use. When used as a foot disk, type A is attached using screws and can be installed on small machines, systems, or devices. Alternatively, the type B version can be adhered to all suitable and clean surfaces by means of an adhesive pad. The steel disk plate is zinc plated, with a blue passivated finish, while the black rubber underlay is vulcanized and is temperature resistant up to 248 F.

 | Worth Reading: AK-47 maker gets into drone biz
The Washington Post featured a piece Feb. 23 on the Kalashnikov Group, the originators of the AK-47 assault rifle, partnering up and getting into the drone-building business. But these aren't just any drones -- they're cheap, can fly pretty far, and are weaponized with explosives to run a kamikaze mission. A real eye-opener.

Saildrones set out to conquer the high seas
After Richard Jenkins set the world speed record for land sailing in a self-designed three-wheeler with a unique wing/tail/tab system, he turned his business and engineering skills to creating a global fleet of 1,000 wind- and solar-powered ocean Saildrones. Their mission is to monitor the state of the seas and sea life in real time -- gathering important info on weather at the same time. The totally autonomous sail craft feature a 23-ft hull, heavy keel, and a 15-ft solar sail wing. Outfitted with a multitude of sensors and at least one camera, they are built to withstand hurricane forces and can travel for thousands of miles for a full year on their own. Jenkins says he hasn't lost a Saildrone yet. Thanks to Bloomberg for this excellent report.
