| Mercedes celebrates: Anti-lock braking system turns 40 At the end of August 1978, Mercedes-Benz and Bosch presented the digital anti-lock braking system (ABS) in Unterturkheim, Germany. A world first, it helped the driver maintain full control over the car's steering even under emergency braking, because the wheels do not lock. ABS was available in the S-Class (model series 116) from the end of 1978. It redefined the role of the vehicle, which, in the future, was to become a partner on four wheels -- a partner that increasingly provided active assistance to the human behind the wheel.

| 12 principles of modern military leadership: Part 3 Leadership is paramount to the success of any army -- and any organization in general. Leaders not only make life and death decisions sometimes, but directly control the climate and quality of life of their subordinates. But what is the real definition of leadership? Capt. Ron Roberts of the U.S. Army's Asymmetric Warfare Group discusses 12 fundamental leadership principles, as well as several educational and inspirational historical examples. How much do they apply to what you do? This is the final article in this series.

| 2,304 motors: LEGO engineers build life-size drivable Bugatti Chiron Nope, it's not a late April Fool's joke. Engineers at LEGO have built a life-size, working Bugatti Chiron (in real life the world's fastest production car) that features more than 1 million LEGO Technic elements and is powered exclusively using LEGO motors. The feat took more than 13,000 man-hours to complete. Really impressive multi-discipline engineering here!

| Nexen expands precision rotary indexer line The Motor Ready Sealed (MRS) precision rotary indexer maintains the benefits of Nexen's existing patented precision roller pinion drive design -- zero backlash, high precision, high torque, and high acceleration -- while delivering significant new benefits. A high roller pinion-to-gear ratio allows users to direct drive the system with the addition of a servo motor, eliminating the cost of a reducer. For high-load applications, the customer can drive the system with a reducer/motor combination. Additionally, the gear-to-pinion reaction loads are fully supported, so the servo motor shaft is not subjected to radial loading, which eliminates the need for costly high output-capacity reducers in high-load applications. All of these features reduce engineering and installation time.

| Engineer's Toolbox: Cushioned aluminum cylinders are 'Ideal' enhancement for sawmill performance Pneumatics technology continues to be a valuable player in many types of industrial automation applications. In the past, heavy-duty steel pneumatic cylinders were preferred for lumber production machinery, but more recently that preference has changed. Now a technology called Ideal Cushioning from Aventics Corp., combined with the lighter weight and relatively lower cost of the company's aluminum pneumatic cylinders, enables Baxley Equipment Co. to supply highly competitive trimmers that accelerate lumber processing while reducing excess piston movement and bounce.

| 100 million random moves: New lifetime spec for rotary micro stage with integral controller New Scale Technologies has significantly increased the lifetime specification for its M3-RS-U Rotary Smart Stage, a precision rotary micro stage with embedded controller. The new specification of 100 million random positions underscores the utility of these compact, all-in-one motion modules for integrating embedded motion inside medical, commercial, and industrial instruments. These rotary stages are ideal for beam steering and mirror positioning applications where precise, point-to-point positioning or dynamic scanning up to 100 Hz is needed. Applications include medical instruments such as surgical lasers and fluorescence microscopes, industrial systems for 3D measurements and remote sensing, optical communications systems, and obstacle detection and tracking systems for robots and drones (UAVs).

| New hybrid nylon TPEs are tough, flexible, and more Nylon Corporation of America has launched an extended product family of nylon (polyamide) -based thermoplastic elastomers (TPEs), also known as polyether-block-amides (PEBA), for a range of applications in the automotive, sporting goods, personal electronics, composite, and specialty films markets. These materials are block copolymers of nylon segments and polyether segments. The nylon block is the hard segment and the polyether block is the soft, flexible segment. NY-FLEX grades are thus hybrid materials, offering a unique combination of rubber-like elastomeric properties and thermoplastic-like processing capabilities. By varying the type and the ratio of these two blocks, a wide range of NY-FLEX grades can be offered.

| Videos+: Technologies and inspiration in action | Opposed-piston diesel engines are crazy efficient
Jason Fenske from Engineering Explained takes a look at the Achates Power opposed-piston engine, which is packed full of unique technology. The supercharged, turbocharged, diesel three cylinder makes use of six pistons, two of which operate in each cylinder. It's a two-stroke design, meaning every time the pistons come together a power stroke occurs, forcing both pistons away from one another and rotating their respective crankshafts. The two crankshafts are geared together to a common output shaft, which powers the vehicle. Research has shown two-stroke opposed-piston engines to be wildly efficient. Three-cylinder designs are the most efficient, and it's possible to achieve brake thermal efficiencies as high as 55percent, a massive improvement for road car engines.
