Roger A Colson

Title: Roger A. Colson and His Piezoelectric Device Patent.

Introduction

Roger A. Colson is an inventor associated with Eindhoven, the Netherlands, and U.S. Philips Corporation. His recorded patent concerns a piezoelectric device designed to maintain a high, constant preload force.

Latest Patents

Colson’s listed patent is “Piezoelectric Device with High, Constant Preload Force.” It describes a stack of polarizable ceramic plates separated by metal electrode plates. A cylindrical housing with two sets of parallel slots, rotated 90 degrees relative to one another, acts as a preloading element with a relatively flat spring-force characteristic across the device’s operating range. Threaded end plugs apply the preload to the stack, and the ceramic plates are polarized after assembly and preloading. Colson is credited with 1 patent.

Career Highlights

The available information connects Colson’s invention to U.S. Philips Corporation. The patent’s design addresses the application of substantial, consistent preload to a piezoelectric stack.

Collaborations

Colson’s listed coworkers include Jan W. Waanders and Herman F. Van Heek.

Conclusion

Roger A. Colson’s recorded patent reflects his contribution to piezoelectric device design, particularly the use of a slotted cylindrical housing to provide a high, stable preload force.
