Omron says its optical sensors can better detect black surfaces

Omron has launched an updated ranges of optical sensors that the company says can better detect black, mirrored and transparent surfaces.

Omron Electronic Components Europe says the new series of optical sensors, also feature a longer detection distance.

Omron B5W sensors are particularly effective at identifying black, transparent, reflective and other hard to detect services, and the new range also features enhanced performance in this area. [Read more…] about Omron says its optical sensors can better detect black surfaces

Cornell scientists develop new material to give robots more sensitive touch

A new synthetic material created by a scientist at Cornell University is said to give robots a “softer touch”.

Developed by PhD student Patricia Xu, at Cornell’s Organic Robotics Lab, the “sensory network” – also dubbed “optical lace” – is said to be similar to the human biological nervous system.

The lab’s paper, Optical Lace for Synthetic Afferent Neural Networks, was published in Science Robotics. [Read more…] about Cornell scientists develop new material to give robots more sensitive touch

Nikon invests $7.5 million in computer vision and deep learning startup Wrnch

Nikon has invested $7.5 million in Wrnch – or wrnch, as the company prefers – a computer vision and deep learning startup.

Established in 2014, wrnch uses deep learning to develop and provide tools and software development kits (SDKs) that enable computers to see and understand human movement and activity.

Wrnch has also used its advanced work in pose estimation technologies to establish ties with major entertainment and communications companies. The company continues its operations in technical development, while raising funds continuously. [Read more…] about Nikon invests $7.5 million in computer vision and deep learning startup Wrnch

NIST unveils tiny new chip for atomic clocks

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock – ticking at high “optical” frequencies – that is much smaller than usual, made of just three small chips plus supporting electronics and optics.

As can be seen from the main picture, it’s smaller than a coffee bean.

Described in Optica, the chip-scale clock is based on the vibrations, or “ticks”, of rubidium atoms confined in a tiny glass container, called a vapor cell, on a chip.

Two frequency combs on chips act like gears to link the atoms’ high-frequency optical ticks to a lower, widely used microwave frequency that can be used in applications. [Read more…] about NIST unveils tiny new chip for atomic clocks

Sick launches new compact image-based code reader

Sick has launched a new compact image-based code reader, Lector621, for reliable detection of 1D, 2D, stacked codes, and plain text.

The high-performance DPM – direct part marking – decoder can read laser or dot-peened codes perfectly, even in the case of low contrast levels, contamination, or poor code quality.

This fills a gap in Sick’s existing portfolio of code readers, by providing a compact solution with increased reading distance, resolution, field of vision, and scanning frequency. [Read more…] about Sick launches new compact image-based code reader

Pepperl+Fuchs launches incremental rotary encoders with new BlueBeam technology

pepperl+fuchs incremental rotary encoders bluebeam — The new ENI58IL with BlueBeam technology

Pepperl+Fuchs has launched blue emitter LEDs which it says ensure increased efficiency.

The new BlueBeam technology for incremental rotary encoders with optical sensing principle increases efficiency when generating signals, says the company.

Specially developed blue emitter LEDs, combined with modern and more finely structured sensing chips, allow a more energetic penetration depth of the blue light in the chip. [Read more…] about Pepperl+Fuchs launches incremental rotary encoders with new BlueBeam technology
