Title: Calum J. Crake and Passive Acoustic Mapping

Introduction

Calum J. Crake is an inventor based in Oxford, Great Britain, associated with Oxsonics Limited. His patent work includes a method for passive acoustic mapping that uses compressive sensing to locate cavitation bubbles.

Latest Patents

Crake is associated with 1 patent: “Passive Acoustic Mapping Using Compressive Sensing.” The invention describes a passive compression-wave imaging system with an array of sensor elements that collect acoustic signals. It uses a random projection to select signal samples and a dictionary of expected sample values for candidate bubble positions. A minimization process then uses the sampled data, the dictionary, and the projection to estimate the bubble positions.

Career Highlights

Crake’s listed patent connects compressive-sensing techniques with acoustic imaging. The system is designed to locate cavitation bubbles by processing signals from multiple sensors, rather than relying on a conventional active imaging approach.

Collaborations

The supplied information lists Richard J. Kozick and Christian Coviello as Crake’s coworkers. The patent is associated with Oxsonics Limited.

Conclusion

Calum J. Crake’s patent work highlights the use of compressive sensing and passive acoustic measurements to identify cavitation bubble locations.
