Title: David Crisp - Innovator in Hygrometry

Introduction

David Crisp is a notable inventor based in Duarte, California. He has made significant contributions to the field of hygrometry, particularly with his innovative approach to measuring dew points. His work is characterized by a deep understanding of the interactions between temperature and moisture.

Latest Patents

Crisp holds a patent for a "High performance miniature hygrometer and method thereof." This invention involves an uncoated interdigitated transducer that is cooled from a temperature above the dew point to a temperature below it. During this process, a parameter of the transducer's signal is measured. The reduction in temperature leads to a monotonic change in the transducer signal, which is primarily sensitive to the water loading on its surface. As the dew point is approached, the slope of the transducer signal curve remains relatively constant until it reaches the dew point, where a clear shift occurs. This innovative measurement technique is notably immune to surface contamination, allowing for accurate dew point identification.
