Abstract:
Disclosed herein is a novel system and method for the remote characterization of visible emissions, and more particularly, to compact, optical sensors which can remotely measure the opacity of a visible emission plume from a stationary source. Assessing visible emissions is important for compliance with environmental regulations and to support the regulatory reporting needs of Federal and State inspectors. By reducing the power consumption of the laser source and the signal processing, a compact, handheld or portable, battery-operable opacity measurement system can be realized while allowing eye-safe operation. The system and method may also be applied to non-stationary sources.

Abstract:
The OFDM scheme based communication system is currently being put into practical use because of its effective use of frequencies and its enhanced resistance to multipath. However, since the OFDM scheme treats multiplexed signals with overlapped spectra, the orthogonality between carriers are corrupted and the error rate characteristic is degraded in the presence of CFO. Furthermore, since locally oscillated signals different by a phase of π/2 are difficult to obtain in demodulating the I/Q signal, an imbalance is caused between the I/Q signals, resulting in degradation in the error rate characteristic. The invention suggests a novel pilot signal, and a method for analytically determining compensation values for CFO and I/Q imbalance and compensating for those distortions using the resulting values. Furthermore, the invention is applicable not only to the OFDM scheme but also to any protocol that involves pilot signals.

A plasma display apparatus and a driving method of a plasma display panel which can improve a gradation expressing ability at low luminance. A magnesium oxide layer containing a magnesium oxide crystal which is excited by irradiation of an electron beam and performs a cathode luminescence light emission having a peak in a wavelength range of 200 to 300 nanometers is provided in each of display cells formed on the plasma display panel. When driving for a plurality of subfields having different luminance weights is performed, a sustaining discharge is caused only once in the subfield having the minimum luminance weight.
