  • Publication number: 20240210356
    Abstract: This document describes techniques and systems for in operando, non-invasive monitoring of byproducts that commonly arise within redox flow batteries. The described techniques and systems allow for accurate, inexpensive, portable, and real-time methods to measure evolution of gas bubbles and precipitates within the electrolyte solutions of redox flow batteries. System operators can monitor and maintain the amount of byproducts within the electrolyte solution by measuring an acoustic attenuation coefficient of the electrolyte solution and changes in the speed at which ultrasonic echoes propagate through the solution. The acoustic attenuation coefficient is measured using an ultrasonic transducer attached to a probing cell, which is connected to an electrolyte flow of a redox flow battery. The acoustic attenuation coefficient provides an accurate, real-time identification of byproducts that is generally insensitive to varying operational temperatures of the electrolyte solution.

  • Publication number: 20230405635
    Abstract: Aquatic tracking makes use of acoustics, rather than other signals that do not travel as well in water. Tracking devices are used to monitor species of fish and other aquatic animals to monitor how their populations and movements are in nature, and how or whether those populations and movements are affected by, for example, hydroelectric dams and other manmade structures and phenomena. Often, the trackers inserted in aquatic animals adversely affect the animals and can lead to mortality or changed behaviors. New solutions that decrease the size and weight of such tracking devices are disclosed herein, enabling better tracking of aquatic animals that is less likely to cause adverse effects to those populations.

  • Patent number: 11415552
    Abstract: This document describes techniques and systems for in operando, non-invasive SOC monitoring of redox flow batteries. The described techniques and systems allow for accurate, inexpensive, portable, and real-time methods to measure the SOC of redox flow batteries. System operators can monitor the SOC by measuring an acoustic attenuation coefficient of the electrolyte in the redox flow battery. The acoustic attenuation coefficient is measured using an ultrasonic transducer attached to a probing cell, which is connected to an electrolyte flow of a redox flow battery. The acoustic attenuation coefficient provides an accurate, real-time SOC measurement that is generally insensitive to varying operational temperatures of the electrolyte solution.
