Latest Patents

One of Bartels' latest patents is titled "Reference-free load-modulated longitudinal rail stress measurement using ultrasonic LCR waves." This invention describes a method for in situ measurement of an acoustoelastic constant of a railway rail. It utilizes an ultrasonic wedge sensor to measure a stress-free time-of-flight in the vertical direction of the rail. By applying a known vertical load, the sensor measures the stressed time-of-flight, allowing for the calculation of the acoustoelastic constant. Additionally, the wedge sensor can measure horizontal time-of-flight, providing valuable data on longitudinal stress.

Another significant patent is "Methods and systems for distal recording of phonocardiographic signals." This invention outlines a method for determining cardiovascular parameters of a patient. It involves placing a phonocardiogram sensor and a blood-pressure waveform sensor at distal locations from the heart. The method calculates a blood pressure pulse transit time value and determines cardiovascular parameters based on this data.
