AI Technical Summary

Technical Problem

Existing ultrasonic surface cleaning methods are not as reliable as mechanical methods in completely removing contaminants, and they can damage surfaces or obstruct visibility, while mechanical methods risk damaging surfaces or coatings.

Method used

A system that uses ultrasonic transducers, generators, and receivers to detect contamination types by analyzing changes in ultrasound characteristics, adjusting cleaning actions based on detected contamination, and applying tailored ultrasonic waves with varying power levels, frequencies, and liquid supply to enhance cleaning efficiency.

Benefits of technology

The system achieves more reliable and efficient surface cleaning by adapting cleaning actions to specific contamination types, reducing energy consumption, and minimizing surface damage.

Abstract

Described is a system for ultrasonic cleaning of a surface, a corresponding method, and a use of the system for cleaning a surface. The method for clearing a contamination from a surface is comprising: generating first ultrasonic waves; coupling the first ultrasonic waves to the surface; receiving at least some of the first ultrasonic waves; detecting a change in one or more characteristics of a plurality of characteristics of the at least some of the first ultrasonic waves in the; determining a cleaning action for the surface from a set of predefined cleaning actions based on the detected change in the one or more characteristics; generating second ultrasonic waves; and coupling the second ultrasonic waves to the surface in accordance with the determined cleaning action.
