PWM Rotation of Brushless DC Motor EC-32 by PIC16F88 and Rotation in terms of Combinational Logic Circuit [PDF]

, 2019
The brushed direct current (DC) motor rotates by applying DC voltage. The brushless DC (BLDG) motor also known as electronically commutated motors (ECMs, EC motors) is categorized into synchronous motors. The method of pulse width modulation (PWM) rotation of the brushless DC motor seems to be not straightforward.

Equivalent Circuit (EC) FDTD Method for the Modeling of Surface Plasmon Based Couplers [PDF]

Journal of Computational and Theoretical Nanoscience, 2008
An equivalent circuit (EC) FDTD method is derived, first for the case of non-dispersive materials and next for the case of dispersive materials. In the later case, both an extended-Drude and a combined Drude/1-pole Lorentz permittivity function, with corresponding circuit (admittance) models, are proposed and shown to perfectly agree with experimental ...

Developmental exposure of bisphenol A induces spatial memory deficits by weakening the excitatory neural circuits of CA3-CA1 and EC-CA1 in mice

Toxicology and Applied Pharmacology, 2021
Bisphenol-A (BPA) is an environmental endocrine disruptor and impairs learning and memory. However, the direct evidence for BPA exposure affecting neural circuits has been limited. In this study, a virus tracing assay has been established to explore the brain's neural circuits.

Repackaging signals, systems and circuits in the core ECE curriculum

1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999
For several years, we have been teaching DSP as a first course in electrical and computer engineering at Georgia Tech. Such a dramatic rearrangement of the introductory material requires a new organization of topics and courses when teaching circuits and systems.

EC-Pl: an Integrated Circuit Layout Program in the Enhanced C Language

The Sixteenth Conference of Electrical and Electronics Engineers in Israel,, 2005
We have designed and implemented a system called EC-PI that automatically lays out integrated circuits. EC-PI provides a test bed for layout algorithms. It is also designed as an experiment in using very high level programming languages for the implementation of such algorithms. This paper reports the structure and performance of the system its well as

A multichannel integrated circuit for neural spike detection based on EC-PC threshold estimation

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
In extracellular neural recording experiments, spike detection is an important step for information decoding of neuronal activities. An ASIC implementation of detection algorithms can provide substantial data-rate reduction and facilitate wireless operations. In this paper, we present a 16-channel neural spike detection ASIC. The chip takes raw data as

A first approach on parallel-monitor integration circuit for energy-capacitor-system (ECS)

11th International Symposium on Power Semiconductor Devices and ICs. ISPSD'99 Proceedings (Cat. No.99CH36312), 2003
A novel integrated circuit has been developed for a high efficiency electric power storage system, called the energy-capacitor-system. The integrated circuit mainly acts as a voltage-regulator to protect electric-double-layer capacitors from overcharging. The clump-voltage of the IC is 2.6 V and its temperature coefficient is 0.05 mV/deg. The developed

openEMS – a free and open source equivalent‐circuit (EC) FDTD simulation platform supporting cylindrical coordinates suitable for the analysis of traveling wave MRI applications

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2012
SUMMARYIn this paper, we present a free and open source platform by using the equivalent‐circuit finite‐difference time‐domain (FDTD) method adapted to cylindrical coordinates to efficiently model cylindrically shaped objects. We will address the special characteristics of a cylindrical FDTD mesh such as the mesh singularity atr = 0 and discuss how ...

Study of charge acceptance for the lead-acid battery through in situ EC-AFM observation — influence of the open-circuit standing time on the negative electrode

Journal of Power Sources, 2001
An influence of the open-circuit standing time after oxidation of the lead electrode was investigated for understanding charge acceptance of the negative electrode of a lead-acid battery. It was confirmed by a potentiostatic transient experiment that charge acceptance of the lead electrode heavily depended on the standing time before charging, and ...
