NAVSEA Dalgren?s Coastal Systems Station (CCS) has developed a hands free communications device. This device could produce life saving results for the individual firefighter who would have an improved ability to communicate in high noise situations. The head contact microphone, usually mounted into the headband of a hat or helmet, transmits spoken words from the wearer through physical contact of a transducer with the human cranium. The device has the ability to reject external noise in excess of 100 decibels. The technology is simple and should be affordable when mass-produced. By rejecting such noise, the microphone assembly could be very useful in a number of high noise environments including fire and police systems, aircraft flight lines, environmental hazardous materials suits, manufacturing plants, and in underwater communications systems such as scuba gear. The technology was first developed in 1989 under a CSS Independent Research/Independent Engineering. Development project funded the Office of Naval Research. A waterproof microphone based on this research was request by the Navy SEALs and has been utilized in their full-face diving mask since 1989. Soundproofing was added during the Gulf War to answer a second request from the SEALs. The potential for firefighting and other applications began in 1997 when the Pittsburgh Fire Department asked CSS to bring the system, which had been developed for the SEALs, to Pittsburgh for an in-house demonstration.

The U.S. Navy has begun an effort to redesign the forward sections of future SSN 774 Virginia-class submarines — one of several moves the service hopes can shrink the ships’ $2.4 b price tag. At the heart of the effort is the proposed removal of the large spherical array of transducers that supports the BQQ-6 sonar system. However, the redesign effort still requires for several issues to be resolved. But if successful the changes could be incorporated as early as the submarine ordered in 2010

Safe guard your cooling system from costly damage with Livorsi’s Raw Water Flow System The Raw Water Flow system is a new patented system that indicates your engine’s water flow volume. This system warns you of a potential problem or danger that would otherwise not be indicated by a water pressure gauge alone, thus preventing cosmetic and structural damage to expensive exhaust headers, intercoolers and cooling systems. What is Water Flow?
