Reliability of a MEMS Actuator Improved by Spring Corner Designs and Reshaped Driving Waveforms [PDF]

Sensors, 2007
In this paper, we report spring corner designs and driving waveforms to improve the reliability for a MEMS (Micro-Electro-Mechanical System) actuator. In order to prevent the stiction problems, no stopper or damping absorber is adopted.

Focal waveforms for various source waveforms driving a prolate‐spheroidal impulse radiating antenna (IRA) [PDF]

Radio Science, 2008
Impulse radiating antennas (IRAs) are designed to radiate very fast pulses in a narrow beam with low dispersion and high field amplitude. For this reason they have been used in a variety of applications. IRAs have been developed for use in the transient far‐field region using parabolic reflectors.

A New Waveform to Solve the Ghosting of BWR EPD [PDF]

Micromachines
The BWR (Black–White–Red) electronic paper display has the advantage of low power consumption and offers a paper-like reading experience. However, refreshing images between black and red can easily produce ghosting images.

Design of Multi-DC Overdriving Waveform of Electrowetting Displays for Gray Scale Consistency

Micromachines, 2023
Gray scale consistency in pixels was extremely important for electrowetting displays (EWDs). However, traditional electrowetting display driving waveforms could not obtain a pixel aperture ratio consistency, which led to the occurrence of gray ...

Common mode output waveforms reduction for Matrix Converters drives [PDF]

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents an alternative Space Vector Modulation (SVM) implemented in Matrix Converters (MC) which improves and reduces the Common Mode (CM) voltage and current output waveforms. The strategy is based on replacing the MC zero vectors for the rotating ones, which reduces the CM voltage derivative and therefore the leakage CM current.
