Tiny Vision Processing Chip Could Reduce System Size for Use in IoT
Scientists have developed a microchip that can capture visual details from video frames using extremely low levels of power. According to the research team, the chip's video feature extractor uses 20 times less power than existing best-in-class chips. The new microchip could reduce the size of smart vision systems down to the millimeter range.

'Quantum Cocktail' Provides Insight Into Magnetic Storage
To speed up the writing and readout of magnetic information from storage devices, researchers are exploring the use of ultrashort laser pulses that can switch magnetic domains in solid-state materials. Although this route shows promise, the large number of magnetic materials interacting with one another has made this approach difficult to study.

Stray Light Absorption in Broadband Wavelengths
Stray Light Absorption in Broadband Wavelengths
Tue, Feb 6, 2018 1:00 PM - 2:00 PM EST
This webinar will discuss the science behind broadband light absorption and introduce materials and techniques for applying optically black coatings that demonstrate ultralow reflectance across a broadband spectra. The presenter, who worked on the development of a number of coating processes for NASA, will provide examples of how low-reflectance technology is currently being used in the visible, NIR and IR wavelengths.
