Open the CIPO recordAbstract From the Canadian patent
A graphical user interface (GUI) and control system (102) for controlling and testing an acoustic source (14). The control system includes real-time data processing (124) of individual source near-field measured signatures and synthesis of array far-field signatures. The control system (102) determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration and when applicable, excluding , failed sources. Source array, and troubleshooting information are presented to a user in real-time over a GUI monitor (126) to allow informed decisionmaking regarding continued and/or modified survey operations and operational parameters.

Why it's free to use
- Filed March 14, 2003 and granted May 1, 2018. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 14, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 14, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
