DC Motor Applications: Micro coreless motors power precision plotter/cutting systems
Paper and cardboard prototype models are essential to test packaging design and functionality. Making them by hand is expensive and imprecise, but cutting plotters can produce perfect in-house mock-ups in minutes. When German cutting-equipment specialist Lasercomb wanted to create a smaller version of its standout piece of configurable cutting equipment, the design challenge proved greater than first expected.

World's thinnest light bulb is one atom thick, reaches temps above 2,500 deg C
An international team of scientists has demonstrated an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament. Creating light in small structures on the surface of a chip is crucial for developing fully integrated “photonic” circuits.

Mike Likes: Noisy Bearings?
Smalley wave springs are ideal for bearing preload. The wave spring preloads the bearing through its outer race, taking up play in the bearing. Preloading will reduce bearing damage, wear, noise, and vibration. The wave spring prevents sliding between the rolling elements. Bearing springs come in metric sizes to match popular bearing sizes. Smalley has over 150 standard springs available, from 16 mm to 580 mm. Customs are available for unique bearing sizes with No-Tooling-Charges™.

Engineer's Toolbox Deep Dive:
Advances in piezoelectric positioners for precision motion control in nanopositioning applications

Ever-increasing requirements for more precise motion control from the optics, biotech, and semiconductor industries have forced manufacturers of piezoelectric positioners to find ways to overcome their limitations, such as travel range and linearity, while preserving their unmatched speed, reliability, and resolution. Stefan Vorndran and Scott Jordan, Physik Instrumente, get into the nitty gritty of using piezoelectric positioners for nanopositioning.

Cooling: Super high-performance DC fan series
Orion Fans has designed a super high-performance 60-mm 24-VDC fan that delivers airflow up to 86 CFM, an increase of more than 25 percent vs. previously available DC fans. The OD6038 XC Series fan offers a superior maximum static pressure value of 2.9" H20, more than three times that of competing fans on the market. Combining high airflow with high static pressure, the high-performance DC fan series is ideal for medical, networking, and telecom equipment. This fan has a dual ball-bearing design and brushless DC motor with auto restart and polarity-protection.

Fasteners: Detent hinge with improved corrosion resistance
Southco has refreshed its successful C6 Detent Hinge series with an improved design that provides increased corrosion resistance for applications that require doors and panels to be held securely at predetermined angles. Snap-on covers fully conceal mounting hardware, creating a modern, streamlined appearance that also enhances cleanability. This hinge eliminates the cost and labor of installing additional components to maintain consistent positioning and is available in a free-swinging style that allows a door or panel to open a full 180 degrees. Ideal for many industries, including off-highway, marine, and specialty vehicles, as well as industrial machinery applications.

NASA gives insider look at Mars glider prototype

A prototype of the Preliminary Research Aerodynamic Design to Land on Mars, which is a flying wing aircraft with a twist, is planned to be ready for launch from a high-altitude balloon later this year. The glider will be released at about at 100,000-ft altitude, which will simulate the flight conditions of the Martian atmosphere.

Stainless steel metal foams can shield X-rays, gamma rays, neutron radiation
Research from North Carolina State University shows that lightweight composite metal foams made of stainless steel and stainless steel/metal hybrids are effective at blocking X-rays, gamma rays, and neutron radiation, and are capable of absorbing the energy of high-impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration, and medical technology applications.

Videos+: Technologies and inspiration in action
Solid Edge ST8 Synchronous Design Intent
This Siemens PLM demonstration highlights the new interface for intuitive synchronous modeling, helping you to focus more on your design and less on the software. Synchronous technology in Solid Edge allows sophisticated wholesale moves of geometry “chunks” without regard for feature history. In Solid Edge ST8, QuickBar options control how a chunk interacts with surrounding geometry during the move.

Jetpack flyer takes Dubai tour
How cool would it be to fly with a real jetpack? See for yourself as Swiss-born Yves Rossy, sometimes called "Jetman" or "Rocketman," dons a 120-lb pack with 7-ft-long carbon-fiber wings and four modified kerosene-fueled model aircraft engines. In this incredible adventure, he flies with fellow jetpack enthusiast Vince Reffet around Dubai. The fuel they can carry provides up to 13 minutes of fly time. Speeds average 125 mph. Thrilling.
