Electrically activated switchable polymer dispersed liquid crystal (PDLC) is suitable for adaptive windows. A particular type requires 20V to become 71% transparent while in the absence of power it is 27% transparent. Glazing transmission changes with light incident angle. As the clearness of a sky changes the fraction changes alter of direct insolation (that has an azimuthally changing incident) and diffuse insolation (that has a largely constant incident). Thus, the effective overall incident angle determining the glazing transmittance also changes. In this work for the first time, the variation of PDLC glazing transmission with clearness index has been investigated.

This Article examines the reasons that “non-transmission alternatives”—including energy efficiency, energy storage, demand response, and distributed generation—have played a very limited role in meeting electricity grid constraints, despite their great potential. It argues that the predominant reasons for this failure lie in structural flaws in transmission planning in the United States, caused in part by questions over how far the jurisdiction of the Federal Energy Regulatory Commission (“FERC”) extends when it comes to these “non-transmission” resources. FERC has declared achieving “comparable consideration” for non-transmission alternatives to be an Agency goal, but has limited the extent of its reforms to opening …

Study Of Transmission Response Of Edge Filters Employed In Wavelength Measurements, Qian Wang, Gerald Farrell, Thomas Freir
Articles
The ratiometric wavelength-measurement system is modeled and an optimal design of transmission response of the employed edge filter is demonstrated in the context of a limited signal-to-noise ratio of the signal source. The corresponding experimental investigation is presented. The impact of the limited signal-to-noise ratio of the signal source on determining the optimal transmission response of edge filters for a wavelength-measurement application is shown theoretically and experimentally.

In our development of a chaotic oscillator technology to produce high-quality communication signals, we have found a novel method for limiting the out-of-band spectral power from chaotic oscillators. This development is an important breakthrough that has allowed us to make a major step toward a commercially viable technology.
