Title: The Innovations of David Wright Dils

Introduction

David Wright Dils is an accomplished inventor based in Fort Worth, TX (US). He holds two patents that showcase his expertise in high voltage control systems. His work has significant implications for various applications, particularly in microfluidic systems.

Latest Patents

One of his latest patents is a low power, scalable multichannel high voltage controller. This invention provides a low voltage control circuit for individually managing high voltage power supplied over bus lines to multiple interconnected loads. An example of such a load is a drive for capillary channels in a microfluidic system. The control is distributed from a central high voltage circuit, which reduces the need for multiple large and expensive central high voltage circuits, thereby minimizing circuit size and cost. Voltage is distributed to each individual load and controlled using several high voltage controller channel switches connected to high voltage bus lines. Each channel switch includes complementary pull-up and pull-down photo isolator relays, with the switching controlled from the central high voltage circuit to achieve the desired bus line voltage. The switching of the photo isolator relays is further regulated in each channel switch using feedback from a resistor divider circuit to maintain the bus voltage swing within specified limits. Current sensing is facilitated through a switched resistive load in each channel switch, with the switching of the resistive loads also managed from the central high voltage circuit.
