New type of corrosion protection for galvanized steel is self-healing
The standard practice to protect metal from corrosion for the last 70 years has been to apply a heavy coat of zinc. But a new product called InterCoat® ChemGuard, instead, reacts with the zinc to form a permanent, covalent bond on the surface of the metal. The product is applied over a light layer of zinc, which reacts with the zinc to dramatically improve its corrosion protection properties. The bond that is formed at the molecular level cannot be washed or worn off.

Lamborghini gives sneak peek of its electric hypercar concept

Is Lamborghini coming out with an all-electric hypercar? Well, they're working on it, but they've got a lot of design and testing ground to cover before we see that day. To get the ball rolling, the Italian luxury sportscar maker has partnered with two labs at MIT to explore creating the super technologies that will go into their Terzo Millennio all-electric concept, including a vehicle that doesn't have a traditional battery energy storage system but does have a self-healing substructure.

You'll FLIP over this benchtop inspection system

Who doesn't like a little flexibility these days? The L.S. Starrett Company has just introduced the HVR100-FLIP, an innovative large field-of-vision (FOV) Benchtop Vision Measurement System that can be used in either a vertical or horizontal orientation and features a high-resolution digital video camera and minimal optical distortion for accurate FOV measurements of up to 90 mm (3.65 in.). The changeable orientation lends itself to an extremely wide array of applications, from flat parts such as gaskets and seals to turned and threaded parts. Includes a 24-in. LCD touch-screen monitor, LED ring light, and motorized drive. Auto Part Recognition can be set to recognize and inspect a part in a few seconds.

How OEMs can save power through direct drive servo technology
How can Direct Drive servo technology help OEM engineers incorporate higher energy efficiency into machine design? This article by Kollmorgen Senior Applications/Systems Engineer Hurley Gill discusses how PMAC Direct Drive servo motor and drive technology not only reduces axis count, mechanical losses and noise, but also delivers increased efficiency and significantly lower cost of operation. Gill presents a determinate measure and a specific method for calculating optimal inertia ratio for managing energy utilization of a servo motor during a machine’s design to maximize power savings.

World's first solid-state 3D LiDAR IC receives two CES 2018 Innovation Awards
LiDAR laser surveying tech is now available to the masses. LeddarTech is the developer and owner of Leddar, a patented solid-state LiDAR sensing technology that constitutes a novel approach to light detection and ranging. Their product recently one two CES 2018 Innovation Awards in the categories of "Embedded Technologies" and "Vehicle Intelligence and Self-Driving." Up to now, this high-resolution 3D-mapping technology has been very expensive to incorporate into planes, autonomous cars, and drones. This advancement should help push forward large-scale production of automotive-grade LiDAR at an affordable price for mass-market vehicles.

Flexible servo drive system for demanding geared motor applications
Siemens has expanded its extensive drive portfolio for servo applications to include the Simotics S-1FG1 servo geared motors, which are designed for use with the Sinamics S120 drive system. Sinamics S120 drives and Simotics S-1FG1 servo geared motors are an integral component of Siemens Totally Integrated Automation (TIA), which reduces engineering time and costs. The units have electronic rating plates, and the motors are connected via the Drive-Cliq system interface, so the system can be brought online quickly. The engineering of the Simotics S-1FG1 servo geared motor includes high efficiency and low torsional backlash for precise, dynamic motion sequences and is available in the following versions: helical, parallel shaft, bevel and helical worm gearboxes with up to 25 transmission ratios.

Extremely fine stainless steel MicroEtch screens
Fine stainless steel MicroEtch Screens are manufactured by Tech-Etch using photo etching technology enabling hole sizes from .003 in. and up. Photo etching enables designers to specify a straight hole or a tapered hole, which facilitates liquid filtration and back-flow cleaning. Unlike stamping, photo etching yields a burr-free product resulting in cleaner, more efficient screens with greater material integrity. MicroEtch screens feature a tighter tolerance on hole sizes and greater dimensional stability than woven wire mesh, making them ideal in applications requiring frequent cleaning or in devices where there is mechanical contact.

Argonne invents reusable sponge for oil-spill cleanup
Engineers and scientists at the U.S. Department of Energy’s Argonne National Laboratory have invented a new foam, called Oleo Sponge, that not only easily absorbs oil from water, but is also reusable and can pull dispersed oil from the entire water column -- not just the surface. The material, based on common polyurethane foam with a few tweaks, offers enormous flexibility and can be adapted to other types of cleanup besides oil in seawater. The team is actively looking to commercialize the material. Click "Learn more" at the top right of the video to get even more details.
