Title: Randall Stevens and His Fluidic Valve Invention.

Introduction

Randall Stevens is an inventor associated with Phoenix, Arizona, and Motorola Corporation. His patent work includes a fluidic valve designed to control fluid flow through a channel using a heat-responsive, bi-phase valve element.

Latest Patents

Stevens is credited with 1 patent: “Fluidic Valve Having a Bi-Phase Valve Element.” The invention describes a valve that changes the flow state in a fluid communication channel. Heating the bi-phase valve element changes it from a high-viscosity state to a low-viscosity state. In that lower-viscosity state, pressure can move an element obstructing the channel into an expanded portion, reopening the channel. Pumped fluid can also move an element from a source chamber into the channel, where it blocks the flow.

Career Highlights

The available information associates Stevens with Motorola Corporation and identifies his patented work in fluidic valve technology. The invention’s described mechanism uses changes in viscosity and fluid pressure to control whether a channel is open or blocked.

Collaborations

Stevens’s listed coworkers include Robin Hui Liu and Justin J. Bonanno. The available information does not specify their roles in the patent or their particular contributions.

Conclusion

Randall Stevens’s patent describes a heat-responsive fluidic valve that uses a bi-phase element and fluid pressure to regulate flow through a channel.
