A system of acoustic sensors, originally developed for underwater mine detection, has been fitted onto gates and locks at Port Canaveral to protect manatees. Since its installation in March 2023, the system has detected seven manatees and saved them from death.
Scientists have developed a unique way to study elephant seals using tiny sensing devices attached to their coats. These devices provide valuable information on sea temperatures and pressure, even at depths not normally reached by research ships or satellite sensing.
A new airborne infrared search and track system, called Risk Mitigation Sensor (RMS), recently passed a key test detecting the launch of a Black Brant missile. The RMS technology has applications in various military aircraft and systems, potentially entering Fleet use within five years.
The Manatee Protection System uses acoustic sensors to detect manatees in the Port Canaveral locks, preventing collisions and saving their lives. The system's advanced technology, developed by ONR-supported scientists, has already saved five manatees during installation and early testing.
The University of Cincinnati researchers have created a novel microsensor for monitoring radioactive and hazardous wastes in the Hanford nuclear facility. The sensor offers three-way selectivity and high sensitivity, allowing it to detect compounds at the nanomolar level.
A team of researchers at Ohio State University has created a single, reliable system that combines three sensing techniques to inspect the quality of high-power laser welds. The system can detect faults with significantly better accuracy than individual sensors alone, and is estimated to cost around $7,500 for manufacturing partners.
Scientists have created artificial receptors with high selectivity to distinguish one molecule from another. The synthetic locks can bind straight, skinny molecules but exclude bent or fat ones, making them useful for applications such as oxidation control and chemical sensing.
The Navy has developed a new miniature sensor to remotely detect and monitor corrosion in inaccessible areas of ships, aircraft, submarines, and weapons containers. The sensor system reduces maintenance costs by allowing for on-demand inspection and retrieval of corrosion information.
The electronic tongue is designed to detect different elements of taste, including sweet, sour, salt, and bitter. The device uses four well-known chemical sensors attached to minute beads placed on a silicon wafer, allowing it to analyse for several different chemical components simultaneously.
A strong consensus has emerged among US seismologists that the seismic network would have detected a blast equivalent to 800 tons of TNT, leading some experts to conclude that India's second round of tests were small and designed to test nuclear bomb components. Pakistan conducted its own nuclear tests shortly after.
A space-based network of sensors is showing value in spotting and tracking storms that are likely to spawn tornadoes. Storms that sent tornadoes through Georgia and Florida were observed from orbit by special sensors a few hours before and after they struck, providing critical data for improving tornado warnings.
The new instrument will provide insight into cloud behavior and lightning's impact on rainfall and El Nino events. LIS data will be used for lightning research, improving understanding of the phenomenon.
Researchers at Ohio University created a new type of chemical sensor that stores large amounts of information indefinitely, allowing workers to be alerted to potential dangers. The sensors can detect specific chemicals in the air and provide accurate readings on exposure levels.
A Penn State engineer has developed liquid crystal fibers that can automatically prevent overload and protect optical sensors from laser damage. The fibers absorb all colors of light and react non-linearly to intensity, allowing low levels of laser light to pass through.
A European research project will develop high-tech sensors for cars to detect air pollution and enforce EU regulations. The sensors will be capable of detecting a range of gases, including CO, in real-time, allowing drivers to take action to reduce their impact on the environment.
