PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids

The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Monolithic White and Multi-Color Lasers Tunable in Full Visible Spectrum

Semiconductor lasers able to emit over the full visible color spectrum have a wide range of practical applications such as solid-state lighting, full-color displays, visible color communications, and multi-color fluorescence sensing. To the human eye, light with a mixture of four monochromatic lasers is visually equivalent to a white illuminant. Current...

A High Flux Solar Thermal Receiver

Technology Description The microchannel based solar receiver (MSR) uses a modular arrangement of microchannels in its design that enable the working fluid to be heated in a concentrating solar receiver. The MSR is made of nickel super alloy and designed with the microchannels operating in parallel, which allows a large amount of flux to be removed by...
