Pulse Density Modulated Soft Switching Cycloconverter
… explores the analysis and design of a pulse density modulated (PDM), soft switching cycloconverter. Unlike standard cycloconverters, the controller in this converter does not adjust thyristor firing angles. It lets only complete half cycles of the input waveform through to the output. This …

Density Modulated Semi-Packed Micro Gas Chromatography Columns
… a MEMS-based separation column design utilizing density modulation of embedded micro-pillars which attempts to optimize the balance between separation efficiency and pressure drop.

Power-efficient and high-performance interference resilientpulse oximeter
… LEDs with two chaotic, non-overlapping pulse density modulated sequences. The deployment of this modulator not only provides more immunity against ambient light but it also offers more control over the pulse oximeter LEDs power consumption resulting in less power consumption under low ambient …
