Abstract
A vibratory assembly having a housing. A transducer is operably coupled with the housing and has a substantially cylindrical shape. An isolator is at least partially disposed between the housing and the transducer. A lens cover is operably coupled with the transducer. A power source includes contacts operably coupled with the transducer. The power source supplies power to the transducer at various frequencies swept around a resonance harmonic to account for mass changes resulting from debris accumulation on the lens cover.
