The Effects of Driving Waveform and Frequency on the Droplet Formation Process

Volume 11: Micro and Nano Systems, Parts A and B, 2007
For a piezoelectric stack (PZT) driven droplet generator, the driving waveform and driving frequency effects on liquid filament shape and droplet characteristics have been studied. A lumped element model (LEM) is developed to study the acoustic-mechanical behavior and the volumetric rejection of the droplet generator.

On the selection of the supply voltage waveform in induction motor drives

IFAC Proceedings Volumes, 1974
SUMMARY When the induction motors are supplied by static inverters alternating currents in the d.c. supply of the inverter are produced. In some applications it is necessary to satisfy prefixed constraints on the amplitude and bandwidth of these alternating currents.

A study on driving waveform of a piezoelectric inkjet print head

SPIE Proceedings, 2007
Inkjet printing technology with a drop-on-demand (DOD) inkjet head has been recognized as one of the versatile and low cost manufacturing tools in the electronics industry. However, general strategy to optimize jetting stability has not been understood well, because of the inherent complex multi-physics nature in inkjet phenomena.

Terahertz waveform considerations for nonlinearly driving lattice vibrations

Journal of Applied Physics, 2019
High-field terahertz (THz) spectroscopy is applied to nonlinearly excite the E phonon-polariton vibrational coordinate in LiNbO3. We compare three THz sources to show that by optimizing the THz waveform, we can drive the atomic motion to large amplitudes and observe nonlinear effects.

Waveform Bounding and Combination Techniques for Direct Drive Testing

1994
Abstract : This paper presents various methods to combine a set of measured test signals into a composite signal. The composite signal represents the set of measured test signals by retaining the significant attributes of the original set of measured test data.

An improved driving waveform reference grayscale of electrophoretic displays

SPIE Proceedings, 2015
Driving waveform is an important component for gray scale display on the electrophoretic display (EPD). In the traditional driving waveform, a white reference gray scale is formed before writing a new image. However, the reflectance value can not reach agreement in each gray scale transformation. In this paper, a new driving waveform, which has a short

A design system for driving waveforms of microcapsule electrophoretic display

2016 IEEE International Conference on Signal and Image Processing (ICSIP), 2016
Due to its advantageous features (eye protection, low energy consumption and capability of being read under any lighting-conditions), Electrophoretic displays (EPD) have been rapidly developed in the past ten years. Different types or production batches of EPD films need different driving waveforms; even in the same device, different driving waveforms ...

A driving strategy dedicated to S.R.: the theory of waveform modification with periodical driving circuit regulation

Twentieth Annual IEEE Applied Power Electronics Conference and Exposition, 2005. APEC 2005., 2005
The theory of waveform modification with periodical driving circuit regulation dedicated to solve the dead time problem of S.R. that occurs in some DC/DC converters is presented in this paper. By utilizing the proposed theory, the existing charge retention driving circuit is analyzed, furthermore a series of novel periodical structure adjustment ...
