Abstract: Various technologies described herein pertain to a radar sensor system including a signal generator that generates a clock signal, start of modulation signal, and local oscillator signal. The radar sensor system includes first and second radar chips. The first radar chip synchronizes a first clock engine in frequency based on the clock signal and the first clock engine in time based on the start of the modulation signal. The first radar chip provides a first radar signal based on the local oscillator signal; the first radar signal is synchronized with the first clock engine. The second radar chip synchronizes the second clock engine in frequency based on the clock signal and the second clock engine in time based on the start of modulation signal. The second radar chip provides a second radar signal based on the local oscillator signal; the second radar signal is synchronized with the second clock engine.

Abstract: An electroluminescent device is provided incorporating an emissive layer comprising a processible polymer matrix such as poly(methylmethacrylate) and a chromophoric component such as an asymmetric stilbene or distyrylbenzene. The chromophoric component is blended with the polymer matrix or covalently attached thereto as a side chain and is selected to emit radiation in the region 400 nm to 500 nm when excited to luminesce.
