Title: SYSTEMS AND METHODS FOR POWER MANAGEMENT IN ULTRASONIC SENSORS
Abstract:
A system and method for controlling the energy of sound waves generated for fluid sensing. The system includes a transducer configured to generate a first sound wave and a second sound wave and to detect a first echo of the first and second sound waves. The system also includes a driver configured to drive the transducer to produce the first and second sound waves. The system also includes a controller configured to compare a signal characteristic of the first echo of the first and second sound waves. The controller is configured to control the driver based on comparing the signal characteristic of the first echo of the first and second sound waves.
