Technique can spot objects hidden around corners
A driverless car is making its way through a winding neighbourhood street, about to make a sharp turn onto a road where a child’s ball has just rolled. Although no person in the car can see that ball, the car stops to avoid it. This is because the car is outfitted with extremely sensitive laser technology that reflects off nearby objects to see around corners. Stanford researchers have designed a laser-based system that can produce images o...
Miniature laser sensors with precise detection ability
Designed with IO-Link technology, the new O300 miniature laser sensors from Baumer are especially for the reliable detection of very small objects and gaps. Thanks to a laser beam which focuses to within 0.1mm and the high repeat accuracy of 0.1mm, objects can be positioned with high precision and follow-up processes controlled exactly.
Outdoor LED lighting surge protection modules
As LED lighting is installed around the world, the need for superior circuit protection to ensure LED luminaires return their promised return on investment has grown. Littelfuse LED lighting surge protection modules are designed specifically to meet the needs of outdoor and commercial LED lighting, with enhanced protection features to guard against catastrophic failure.
Maximum surge protection for outdoor LED lighting
Global fuse company, Littelfuse, has a long history of pioneering innovative products and services to serve the engineering needs of customers and industries. The company has recently introduced the LSP05G. This thermally protected Surge Protective Device is a self-protected device specially designed to be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection. It has been developed with Littelfuse’s ...
Protecting luminaires in Class I or Class II installations
Global circuit protection company, Littelfuse, has announced the LSP05GI series - a 10kV/5kA capable surge protection module with IEC/EN 61643-11 certification to help luminaire manufacturers meet the latest testing standards. It also provides double insulated cable to simplify cable routing design in the luminaire.
Next-gen CoB LEDs offer five percent greater efficiency
A range of fourth generation chip-on-board (CoB) LEDs has been introduced by Lumileds. The company claims that the LUXEON CoB Core Range leads the market in efficacy and quality of light. With the new LUXEON CoB Core Range, Lumileds sets a new standard with five percent greater efficacy than the nearest competitors. Efficiency is not compromised at high colour rendering index.
Metasurface-based lens atop a MEMS platform
Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. In the collaborative effort between the U.S. Department of Energy's (DOE) Argonne National Laboratory and Harvard University, researchers successfully crafted a metasurface-based lens atop a MEMS pla...
Super-resolution microscopy in space and time
Super-resolution microscopy is a technique that can “see” beyond the diffraction of light, providing unprecedented views of cells and their interior structures and organelles. The technique has garnered increasing interest recently, especially since its developers won the Nobel Prize in Chemistry in 2014. But super-resolution microscopy comes with a big limitation: it only offers spatial resolution.
Next-gen photoelectric sensors pilot the future of sensing
SICK’s next-gen W16 and W26 smart sensors with ‘BluePilot’ alignment are at the helm of a streamlined portfolio of photoelectric sensors, radically-upgraded to optimise ease-of-use with complete object detection reliability. The W16 and W26 proximity, reflex and through-beam sensors are manufactured at a purpose-built, fully-automated production facility in southern Germany. They mark the culmination of a two-year, multi-mi...
Cross and point line lasers offer increased visibility
Reality capture technology company, Leica Geosystems, has announced the new Lino series of cross and point line lasers, specially created to ensure supposedly outstanding laser visibility. The clever power concept with Li-ion rechargeable batteries enables users to work without inconvenient interruptions. Thanks to the ingenious adapter concept with its strong magnets, the laser is also simple and quick to position.
