An Advanced Monitoring, Control, and Display Module for an Underwater Portable Life Support System

An Advanced Control and Display Module has been developed for an Underwater Portable Life Support System. The system architecture may be applicable for future EVA applications. The Module employs a Single Chip Microcontroller, an Electroluminescent Display, and an Operator Control Panel. The Module automatically controls the amount of oxygen in the diving mixture as a function of depth. Predive and postdive checkout, present diving status, and emergency procedures are all available through the display.
