Title: David Alan Uhen: Innovator in Electroporation Technology

Introduction

David Alan Uhen is a notable inventor based in Burlington, WI (US). He holds a total of 3 patents that showcase his contributions to technology, particularly in the field of electroporation.

Latest Patents

One of his latest patents is an electronic tablet case. Another significant invention is an apparatus for electroporation. This apparatus is designed to store a level of charge, specified by a user, on a capacitor. The charge is delivered to a cuvette through an optically isolated high voltage switch. The capacitor is charged using a current mode pulse width modulation control circuit. This circuit monitors the current in the primary winding of a transformer and supplies a pulse width modulated signal. This limits the current on every pulse to a level set by the microcontroller. The controlled amount of energy is transferred through each pulse to the capacitor. The microcontroller also monitors the voltage on the capacitor to predict the number of pulses necessary to store the requested amount of charge. Once the required voltage is reached, it is delivered to the cuvette through the high voltage switch. The voltage and current at the cuvette are monitored, allowing the microcontroller to calculate the impedance and detect errors in the solution's composition.
