New Spirawave® Wave Spring Series
Smalley's Nested Spirawave Springs are now available standard from Smalley. Nested springs are flat wire wave springs with multiple turns, coiled in parallel to produce high forces. When replacing a stack of single-turn wave springs with one nested spring, misalignment and uneven loading are eliminated, making assembly and installation simple.

How HondaJet used NASA facilities for over-the-wing engine mount development
These days, computers handle a lot of the work for designing an airplane, but when it comes to seeing how well the new design will really handle in the air, there's nothing like a real-life test in a wind tunnel. NASA's National Transonic Facility is one of the best, and when the agency's engineers aren't using it to test their own aeronautic innovations, private companies are sometimes able to use the available space by reimbursing NASA for time not already scheduled.

Best-kept secret in the circuit breaker industry
When STELPRO, a Quebec-based manufacturer of integrated heating solutions for the HVAC industry, asked partners all along its supply chain to identify cost-saving opportunities, installing NOARK miniature circuit breakers in panels on all their equipment was one solution that provided long-term quality and savings (typically 30 to 50 percent in price). NOARK's five-year warranty was a huge added bonus.

New cellphone, in-ear tech could help military locate shooter from the first shot
A French researcher has developed a proof of concept that uses tactical earmuffs or earplugs with built-in microphones to capture a shooter's acoustic information and transmit it to a soldier's smartphone to display shooter location in real time.

KLM invests in Flying-V blended wing concept aircraft research
Is "V" the shape of things to come? With their eyes on sustainability, lightweighting, and efficiency, KLM Royal Dutch Airlines has signed a new cooperative agreement to work with Delft University of Technology in the Netherlands to further develop the blended wing, boomerang-shaped "Flying-V" aircraft design, which aims to carry the same number of passengers as the Airbus A350 (314) but use 20 percent less fuel.

Image - Joining fiber-reinforced plastics to metal
Joining fiber-reinforced plastics to metal
Designing and building lightweight vehicles challenges manufacturers to combine functional metal components with lighter-weight, highly durable carbon fiber-reinforced plastics. Researchers from the Fraunhofer Institute in Germany use a variety of solutions for joining such disparate materials -- including a new one where resin melts into and surrounds a metal plate. They use a simple scooter as an application example.

Image - Right-sizing valve manifolds linked to smart machine design
Right-sizing valve manifolds linked to smart machine design
Valves are generally sized by cylinder bore, actuation speed, and required pressure. In the past, the entire valve manifold would be sized based on the largest force/speed requirements of the pneumatic system, or by splitting between two manifolds (low and high pressure/flow). However, this methodology results in waste, both in terms of compressed air and the expense and size of the manifold, not to mention the labor needed to install two manifolds.

Image - Alternative to traditional drive systems
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 percent 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.

Top Tech Tip: Stepper or servo motor --
Which should it be?

Bring out the full capacity of your machines through the most efficient mechatronic design. Hurley Gill, Senior Applications/Systems at Kollmorgen, outlines servo and stepper motor baseline capabilities for selection criteria like torque, speed, accuracy, and repeatability. Technical advantages and disadvantages are discussed, helping machine designers select the best motor-drive system for their application.

Image - Two-component adhesives revolutionized with light fixation
Two-component adhesives revolutionized with light fixation
DELO has developed light fixation two-component epoxy resins that provide unprecedented process speed -- only 5 sec irradiation time! Thanks to the hybrid chemistry of DELO-DUOPOX DB8989, users will realize faster, less complex production processes and simplified logistics. Reliable final curing, including shadowed areas, is done the same way as regular two-component products, either at room temperature or at a faster speed by using heat curing at 80 C for 60 min. The adhesive is able to achieve a tensile shear strength of 28 MPa on aluminum. Applications include structural bonding of rare earth magnets in electric motors. It is also suitable for opto-electronic applications in cameras for automated driving due to low outgassing and shrinkage.

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.

Image - Dual-mode automotive image sensor
Dual-mode automotive image sensor
The OV2312 automotive image sensor from OmniVision Technologies enables multiple functions in one camera, reducing the total system cost, space, and power budget for driver state monitoring (DSM) and viewing applications like video conferencing. The ability to capture both RGB and IR images with one global shutter (GS) sensor reduces the number of cameras needed. It provides dual-mode cameras with motion-artifact-free images at high resolutions of 1,600 x 1,300 at 60 fps and 1,280 x 720 at 90 fps. Because this is the smallest 2MP GS sensor in its class, cameras can be placed out of sight from drivers and passengers.

Videos+: Technologies and inspiration in action
Voodoo Manufacturing triples 3D-printing output with Universal Robots
Voodoo Manufacturing was racing against time to scale up their 3D-printing business by automating the loading and unloading of printer plates. The Brooklyn startup chose a UR10 robot with a Robotiq gripper and has now tripled output, enabling them to compete with injection molding. Why did UR win? Because no other collaborative robot offered the ease of integration now provided through the Universal Robots+ platform.
