DARPA Funds Tech to better Detect Whales

Charles River Analytics won a $1.5 million follow-on contract from the Defense Advanced Research Projects Agency (DARPA) to develop a multi-sensor fusion module that incorporates deep learning to autonomously and accurately detect whales and other aquatic mammals.To protect marine mammals from collisions and sonar exposure, sailors must keep a vigilant lookout. Operators of remotely operated vehicles must also stay alert, and uncrewed surface vehicles’ (USVs) currently limited and narrow video feeds create risk, too. To reduce the strain on human lookouts, and give USVs the ability to steer clear

Sonar: Critical to Bridge Demolition, Recovery

What happens when a bridge or other structure is no longer in use and needs to be removed? There are several options, the most exciting of which is demolition.These jobs require caution and careful planning to guarantee safety and ensure that debris does not cause damage to the local waterways or roads. Four of the most common methods are bursting, hydraulic breakers, dismantling, and explosives.The Historic 1936 Highway 47 Bridge over the Missouri River was demolished this past spring. The old bridge was located 12’ from the new bridge that was built over the past several years. Being as close
