New Cmos Universal Constant-Gm Input Stage, Vladimir I. Prodanov, Michael M. Green
New Cmos Universal Constant-Gm Input Stage, Vladimir I. Prodanov, Michael M. Green
Electrical Engineering
Conceptually new constant-Gm input-stage architecture is presented. It provides near constant net transconductance independent of transistor operating region-strong, moderate or weak inversion. One possible implementation of the proposed architecture is discussed in details. Its operation has been experimentally verified. Results from performed measurements are included.
A Neural Network Pruning Algorithm With Embedded Gradient-Conjugate Training For The Identification Of Large Flexible Space Structures, Xiao-Hua Yu
Electrical Engineering
The choice of network dimension is a fundamental issue in the design of artificial neural networks. A larger neural network is powerful for solving problems while a smaller neural network is always advantageous in real-time environment where speed is crucial. In this paper, a network pruning algorithm with embedded gradient-conjugate training is investigated and applied to the identification of a large flexible space structure. Computer simulation results show that this approach can dramatically reduce the size of neural network while maintaining compatible identification accuracy.

Signal Monitoring Apparatus For Wavelength Divison Multiplexed Optical Telecommunication Networks, Dennis J. Derickson, Roger Lee Jungerman
Electrical Engineering
A detector array spectrometer simultaneously monitors wavelength, power, and signal-to-noise ratio of wavelength division multiplexed (WDM) channels in telecommunication networks. A spectrometer spatially separates signals from the WDM channels according to the channels' wavelengths. The separated signals are incident on an array of split-detectors that conforms to the spatial separation of the signals provided by the spectrometer. While the split-detectors are positioned to receive a signal from each WDM channel, a noise detector is positioned between adjacent split-detectors to measure noise. A common mode output from two halves of each split-detector indicates the power in a WDM channel, while a …

Optimization Of Network Signal Timing, Xiao-Hua Yu, Allen R. Stubberud
Electrical Engineering
A typical urban traffic network is a complicated large-scale stochastic system which consists of many interconnected signalized traffic intersections. This paper develops a decentralized real-time adaptive control strategy for the traffic networks based on Markov decision theory. Computer simulation results of this new approach on a five intersection traffic network indicate significant improvement over the traditional fully actuated control algorithm.
Electroluminescent Device Having Electroluminescent Compound And Liquid Crystalline Compound, Rifat A.M. Hikmet, David Braun, Aemilianus G.J. Staring, Hermanmus F.M. Schoo, Johan Lub
Electroluminescent Device Having Electroluminescent Compound And Liquid Crystalline Compound, Rifat A.M. Hikmet, David Braun, Aemilianus G.J. Staring, Hermanmus F.M. Schoo, Johan Lub
Electrical Engineering
A description is given of an electroluminescent device (1) having an LED structure, which is composed of an active layer (7) of oriented liquid-crystalline and electroluminescent compounds and a transparent positive electrode layer (5) which is preferably made from an electroconductive polymer. By previously rubbing the electrode layer (5) in one direction with a velvet cloth, an orientation is induced in the molecules in the active layer (7), the orientation being frozen by cooling or polymerization. The electroluminescent device (1) emits polarized light whose direction of polarization is parallel to the direction of rubbing.

Final Report: City Of Anaheim/Caltrans/Fhwa Advanced Traffic Control System Field Operational Test Evaluation Task C, Video Traffic Detection System, Art Maccarley, Cal Poly Transportation Electronics Laboratory
Electrical Engineering
A technical evaluation was conducted as a subtask of the “City of Anaheim Advanced Traffic Control System Field Operational Test (FOT)”, funded by the US DOT / FHWA and the California Department of Transportation. Partners for this FOT are the City of Anaheim, Odetics Inc. of Anaheim, JHK Consulting, and the California Department of Transportation. This report is the result of evaluation Task C “VTDS Evaluation”, one of three evaluation tasks covering components of the FOT. The component evaluated under Task C is a video-based vehicle detection system for actuation of traffic signals at intersections. This system, referred to as …
Crosstalk In Passive Matrix Polymer Led Displays, David Braun
Crosstalk In Passive Matrix Polymer Led Displays, David Braun
Electrical Engineering
Passive matrix displays based on polymer and organic light-emitting diodes (LEDs) suffer from crosstalk, the emission of light from pixels other than those selected. This article explores the topic of crosstalk both with an approximate but analytic model and by means of more exact circuit simulation in order to explain the causes of crosstalk and to quantify the consequences. We conclude that crosstalk has implications for display power consumption.

Electroluminescent Device Comprising A Transparent Structured Electrode Layer Made From A Conductive Polymer, Aemilianus G. J. Staring, David Braun
Electrical Engineering
An electroluminescent (EL) device is (1) composed of polymeric LEDs comprising an active layer (7) of a conjugated polymer and a transparent polymeric electrode layer (5) having electroconductive areas (51) as electrodes. Like the active layer (7), the electrode layer (5) can be manufactured in a simple manner by spin coating. The electrode layer (5) is structured into conductive electrodes (51) by exposure to UV light. The electrodes (9) and (51) jointly form a matrix of LEDs for a display. When a flexible substrate (3) is used, a very bendable EL device is obtained.
