Abstract: An oral care appliance (100), such as an electric toothbrush, utilizing non-linear resonant systems is described herein. In one exemplary embodiment, the oral care appliance includes a longitudinal shaft (102), a brush head (130), and a handle (190). The handle includes a motor (140) that generates a first amplitude (404) for the brush head based on the brush head being outside of the user's mouth, when no mass is applied to the brush head. In response to the brush head being inside of the user's mouth, when mass is applied, such as by pressing the brush head against the teeth, the motor causes a second amplitude (410) to be generated for the brush head that is larger than the first amplitude.

Abstract: The present disclosure includes a method for processing a beer stream for the recovery of oil. The method include a step of extracting oil from a beer stream into an organic phase comprising an organic solvent to provide in the organic phase at least a portion of the oil. In general, a beer stream refers to a composition containing alcohol, water, oil, and particulates, and can be a result of a fermentation process. When the beer stream is a beer stream from a fermentation process, it can be referred to as a fermentation broth even if it is no longer being subjected to fermentation. The beer stream can contain other components commonly found in a stream coming off a fermentation process such as, for example, glycerol and acetic acid. A method for producing ethanol, and an ethanol production facility are provided.
