Eliminate Downtime and Coupling Breakage in Encoders Servometer flexible nickel metal bellows couplings are a proven reliable alternative to spiral wrap style couplings in encoder applications that require shaft-misalignment, low torque and high torsional stiffness. Choose from a variety of bore sizes, diameters, lengths and torque values. We can offer a standard part or a custom design based on your requirements.

| 3D printing with instant results? LLNL can do that | |
Instant gratification has come to 3D printing in a very big -- and a very little -- way, thanks to new, demonstrated advances by researchers at Lawrence Livermore National Lab. Using laser-generated, hologram-like 3D images flashed into photosensitive resin, the team has discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing.

1,000x resolution: New depth sensors sensitive enough for self-driving cars For the past 10 years, the Camera Culture group at MIT's Media Lab has been developing innovative imaging systems -- from a camera that can see around corners to one that can read text in closed books -- by using "time of flight," an approach that gauges distance by measuring the time it takes light projected into a scene to bounce back to a sensor. Now members of the group have developed a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold.

Ford chases a retro spirit with 50th anniversary Mustang Bullitt Ford has a special-edition model due out this summer -- the all-new Mustang Bullitt, which celebrates the 50th anniversary of the movie "Bullitt" and the car in its iconic 10-minute San Francisco chase scene with Steve McQueen as the driver. While the 2019 475-hp model is cool, the story behind the original movie car and how it resurfaced is just as interesting.

Mike Likes: C Series and CM Series springs get really small Smalley has expanded the Crest-to-Crest® Wave Spring Series. Smalley's popular C (imperial) and CM (metric) Series have been expanded; standard sizes are now available from stock down to .188 in. and 5 mm in diameter. Smalley Wave Springs can replace conventional coil springs while occupying only half the space and providing the same force and deflection. Request complimentary samples today!

Toolbox: Producing large 3D-printed metal parts gets automated 3D Systems has introduced a next-generation additive metal production platform designed to allow manufacturers to easily scale their 3D-printing efforts and integrate them seamlessly into the factory floor. Based on the company's Direct Metal Printing (DMP) precision metals technology, the automated DMP 8500 Factory Solution features an efficient and fully integrated workflow -- from powder in to part out -- to produce repeatable, high-quality parts with a lower total cost of operation (TCO).

Chairless exoskeleton to solve long-standing problem The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. Operating a switch on the strap turns the flexible construct into a stable seat. Two small FAULHABER DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

Selection tips for rodless electromechanical and electric rod actuators When you specify a linear actuator, some basic decisions come first. Do you go with electric or fluid-powered? Do you need the push/pull of an electric rod actuator or the load-carrying action of a rodless electromechanical actuator? Aaron Dietrich from Tolomatic may have your answer. Dietrich has compiled some very good tips for selecting these actuator types. Learn about selecting linear actuators.

Fast and compact direct-drive micro-positioning stages Precision motion and nanopositioning leader PI (Physik Instrumente) delivers a family of compact linear and rotary stages driven by ceramic direct-drive motors. The patented ultrasonic motors provide smooth motion with high resolution and a high dynamic range. The self-clamping motor principle locks the stage into place, devoid of creep, once a target position has been reached. This intrinsic brake-like behavior comes at no extra cost and provides advantages that are not available with classic electro-magnetic drive technologies. Two linear stages with 18-mm and 22-mm travel are available, as well as an XY stage providing 22 mm x 22 mm. Several encoder options are standard. Applications include medical devices, optical instrumentation, photonics alignment, and super-resolution microscopy. View the specs, datasheet, and more. Read tech article about ultrasonic motors.

New anti-static Super Air Knife with 34% better performance EXAIR's new Gen4 Super Ion Air Knife eliminates static electricity 34% better at low inlet pressures, which saves compressed air and money. Production speeds, product quality, and surface cleanliness can improve dramatically. It eliminates static on plastics, webs, sheet stock, and other product surfaces where tearing, jamming, or hazardous shocks are a problem. Gen4 products have undergone independent laboratory tests to certify they meet the rigorous safety, health, and environmental standards of the USA, EU, and Canada that are required to attain the CE and UL marks. They are also RoHS compliant. New design features include a metal armored high-voltage cable to protect against abrasion and cuts, integrated ground connection, and electromagnetic shielding.

| Millimeter-scale Delta robot is precise and fast | |
Because of their high precision and speed, Delta robots are deployed in many industrial processes, including pick-and-place assemblies, machining, welding, and food packaging. Over time, roboticists have designed smaller and smaller Delta robots for tasks in limited workspaces, yet shrinking them further to the millimeter scale with conventional manufacturing techniques and components has proven fruitless. A new design, the milliDelta robot, developed by a team at Harvard's Wyss Institute for Biologically Inspired Engineering, overcomes this miniaturization challenge. By integrating their microfabrication technique with high-performance composite materials that can incorporate flexural joints and bending actuators, the 15-mm x 15-mm x 20-mm milliDelta can operate with high speed, force, and micrometer precision, which make it compatible with a range of micromanipulation tasks in manufacturing and medicine.
