Ultrasonic in situ Respirator Seal-Leakage Detection with Real-time Feedback Capabilities
This CDC invention entails methods and apparatuses for in situ testing seal integrity and improved operation of respiratory masks (respirators). A variety of external factors, such as individual face shape, user environment, mask age and material used to construct the respirator, can lead to device malfunction and failure to sufficiently protect a...

Method to actively control the direction of hydraulic fractures using ultrasonic waves
Hydraulic fracking has revolutionized the oil industry since the first successful application in 1950. In hydraulic fracking, high pressure fluids are injected into wells in order to crack and thereby render the oil containing substrate more permeable thus allowing the entrapped oil and gas to flow more freely. Wells may be drilled vertically hundreds...
