|Magnetic diode could increase battery life of electronic devices 100x|
Among the chief complaints for smartphone, laptop, and other battery-operated electronics users is that the battery life is too short and, in some cases, that the devices generate heat. Now, a group of physicists led by Deepak K. Singh, associate professor of physics and astronomy at the University of Missouri, has developed a device material that can address both issues.

|Mike Likes: Alternative to traditional drive systems|
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet and 99% efficient. Stainless steel makes the system corrosion resistant, with a long life of up to 36 million meters. Nexen’s RPS provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.
|Air spray: The comeback of stunning military aircraft paint jobs|
Eight Oregon Air National Guard members received a call to arms. Their wing commander handed them an assignment, stressing high priority. They worked 33 consecutive days, some pulling night shifts. Their orders: Paint a Boeing-built F-15 Eagle jet fighter in a manner that would elevate base morale at Kingsley Field in Klamath Falls, OR, and commemorate the Air National Guard’s 75th anniversary across the state. By Dan Raley. [Editor's Note: We liked this story so much for Memorial Day last year, we thought we'd share it again.]

|Choosing between brush and brushless DC motors: What are the tradeoffs?|
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

|Entry-level industrial-grade 3D printer|
The FabPro 1000 from 3D Systems is a new entry-level system that packs 30 years of industrial 3D-printing know-how into its design to deliver superior quality at up to 3X faster high-throughput print speeds than competing printers. Digital Light Printing (DLP) Stereolithography uses a projector to image each layer within a UV-curable, liquid plastic material. This easy-to-use system, with a build size of 125 x 70 x 120 mm (4.92 x 2.76 x 4.72 in.), has 3D Sprint file preparation and print software included -- all at a price of $4,995.

|Linear miniature torque splines and nuts|
Helix Miniature Torque Splines provide a convenient and efficient device that allows low-friction linear motion while transmitting torque. In a Helix PT Spline assembly, the high-strength composite polymer bushing carries the load between the rotating member (inner race) and the rotating/translating member (bushing). Helix PT Splines are coated with Helix H10X PTFE coating for long life and anti-friction. Available in three bushing styles: Cylinder Mount, Thread Mount, and Anti-Backlash.

|Smith Metal Products adds Titanium Metal Injection Molding capabilities|
Smith Metal Products has added Titanium Metal Injection Molding (TiMIM) capabilities to its MIM portfolio of materials that include stainless steels, alloys, and ceramics. TiMIM involves mixing powdered Titanium metal with a binder material to compose a feedstock capable of being handled by injection molding equipment. Metal injection molding allows complex Titanium parts to be shaped with precision in a single operation and in high volume as compared to traditional Titanium machined metal components.
|High-performance, high-load linear stages for industrial use|
The new reference-class linear stages from precision nanopositioning global leader PI (Physik Instrumente) are available in ballscrew (L-417) and linear motor (V-417) configurations. Both cost-effective designs offer high resolution with improved tracking performance, smaller tracking error, and improved settling time. Applications include laser cutting, scanning, digital printing, electronics assembly and inspection, and more. The L-417 precision heavy-duty ball screw model easily accommodates a load capacity of 450 N on its 166-m width frame with a travel up to 813 mm. Powered by an ironless linear motor, the V-417 has a similar load capacity, width, and travel range.

|Pushing the limits of motorcycle design and manufacturing|
Matt Chambers, founder and CEO of Confederate Motors, talks about the impact that 3D Systems' Quickparts rapid parts and prototypes service has on his design-and-build business. With the exception of some engine components, wiring, wheels, tires, and lighting, 3D Systems makes every part of the super-boss P51 Combat Fighter motorcycle, saving a tremendous amount of time and hassle for Confederate Motors by being able to consolidate part production with one primary vendor. Quickparts is now part of 3D Systems On Demand Manufacturing.
