A novel triple-frequency controlled lamp network with end-of-life detection for architectural dimming of compact fluorescent lamps

APEC '99. Fourteenth Annual Applied Power Electronics Conference and Exposition. 1999 Conference Proceedings (Cat. No.99CH36285), 1999
Ballast designers face great difficulty in trying to dim the compact fluorescent lamps (CFLs) below 40%. The symptom is a lamp current oscillation which results in excessive flickering. This is due to the fact that CFLs are known to exhibit high negative resistance during dimming. Also, CFLs tend to draw excessive power at the end of their useful life.

Novel wavelength division multiplex-radio over fiber-passive optical network architecture for multiple access points based on multitone generation and triple sextupling frequency

Optical Engineering, 2014
An innovative wavelength division multiplex-radio over fiber-passive optical network architecture for multiple access points (AP) based on multitone generation and triple sextupling frequency is proposed and dem- onstrated. A dual-drive Mach-Zehnder modulator (DD-MZM) is utilized to realize the multitone generation.

Triple band frequency selective surface design for 5G mm‐wave communication with artificial neural networks

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields
AbstractHigh‐performance frequency selective surfaces (FSSs) have gained attention for their spatial filtering characteristics in 5G communication systems. In this work, we propose an efficient and accurate design methodology for the FSS. Three different artificial neural network methods (ANN) are employed, and their performances are compared for ...

Performance of non-coherent signal detection of mary frequency-shift keying in triple layer Wireless Sensor Networks

2011 International Conference on Image Information Processing, 2011
In this paper, an innovative low complexity triple layer Wireless Sensor Network (WSN) system is proposed, which monitors M-ary events like temperature, pressure, etc. with the help of geographically distributed local sensors. These local sensors convey signals to the fusion centre using M-ary Frequency Shift Keying (MFSK) modulation scheme over ...

An Algorithm of Single-Epoch Integer Ambiguity Resolution for Reference Stations of BDS Triple-Frequency Network RTK

2016
An algorithm of single-epoch integer ambiguity resolution for reference stations of BDS triple-frequency network RTK is proposed in this paper. The mathematic models, resolution process, and result analyses are given in detail. The main idea of this method is to resolve extra-wide-lane and wide-lane ambiguity by using the method of TCAR, determine the ...
