Title: **The Innovations of Jolyon DeFreitas: Pioneering Phase Based Sensing**
Introduction
Jolyon DeFreitas, located in Dorset, GB, is a distinguished inventor notable for his contributions to the field of sensing technologies. With three patents to his name, his work focuses on improving the efficacy of transducers in various applications, particularly in seismic surveying.
Latest Patents
Jolyon's latest patents revolve around the concept of phase based sensing. The first patent describes a method of sensing using a phase based transducer whereby the transducer responds at multiple sensitivity levels. This innovation allows for effective output without overscaling across a broad range of signal levels, making it especially beneficial when used with multiplexed arrays of fiber optic sensors for seismic surveying. Additionally, the patent outlines methods for sensor calibration and noise reduction.
The second patent further elaborates on the interrogation of phase based transducers. In this technique, the transducer's state is compared at two different points in time to ascertain the rate of change represented as a phase change. The derivative measurement obtained from this method is particularly advantageous as it focuses on low sensitivity measurements, helping to mitigate overscaling effects during high amplitude signals. For instance, the proposed method can effectively reduce the amplitude of a signal centered around 800 Hz by 60 dB over a brief period.
