ABSTRACT:
A safety system for underwater propulsion devices operated by scuba divers includes sensors that detect the vertical velocity of the device. If the descent or ascent is greater than 60 feet per minute, the system reduces the vertical speed by changing the pitch of the device or reducing the speed of the device. By regulating the vertical speed, the device can be used safely with less chance of injury to the scuba diver due to rapid compression or decompression.
