    • Techniques and apparatus inhibit, limit, or remove biofouling and certain inorganic accumulations, to increase the longevity of accurate in-situ oceanographic and other underwater measurements and transducing processes. The invention deters formation of an initial bacterial layer and other precipitation, without harming the environment. The invention integrates an ultrasonic source into a sensor or other device, or its supporting structures. The ultrasonic source vibrates one or more critical surfaces of the device at a frequency and amplitude that dislodge early accumulations, thus preventing the rest of the fouling sequence. The ultrasonic driver is activated for short periods and low duty cycles, and in some cases preferably while the device is not operating.
    • 技术和装置抑制,限制或消除生物污垢和某些无机物聚集,以增加准确的原位海洋学和其他水下测量和转换过程的寿命。 本发明阻止了初始细菌层的形成和其他沉淀,而不损害环境。 本发明将超声波源集成到传感器或其他装置或其支撑结构中。 超声波源以一定的频率和幅度振荡器件的一个或多个临界表面,从而阻止早期积聚,从而防止其余污垢序列。 超声波驱动器在短时间和低占空比下被激活,并且在一些情况下优选地在设备不工作时被激活。
