Acoustic System for Passive Acoustic Monitoring and Acoustic Communications

The technology comprises an integrated passive acoustic monitoring system capable of long-term monitoring, capturing high-quality, distinctive sonar sounds from aquatic environments. The acoustic monitoring system, incorporating a hydrophone, a micro-processing board and a mechanical release system

Ceramic composite and method to prepare the composite

This technology is a high temperature self-repairing carbide ceramic matrix composite. It is produced using titanium and a porous CfC composite preform matrix. Titanium and the composite preform matrix are placed in a crucible and spark plasma sintering is used to melt titanium so that it
