Smart buoyancy assistant

Abstract

A diving system can include a smart buoyancy assistant to automatically adjusts the amount of air in the buoyancy control device (BCD) to maintain buoyancy control during the descent, level hold, or ascent of a dive. In some instances, the smart buoyancy assistant is automatically activated when the system is submerged to a predetermined activation depth. Additionally, the smart buoyancy assistant can add air to the BCD if the system drops below a predetermined maximum depth. The system can capture data representing dive metrics and sensor data and can report such data to a computing device to further aggregate the data and generate dive models to improve the performance of the system. The computing device can use the aggregated data to perform dive analysis and determine if the system is over or under adjusting the amount of air to improve the dive models.
