Abstract
A means for deriving a metric of tooth mobility based on force or motion data acquired from a sensor integrated in an oral care device and acquired during an oral cleaning session. By processing a waveform of the sensing signal to detect one or more signal characteristics, and further acquiring one or more characteristics of the tooth-device mechanical engagement, a standardized metric of tooth mobility can be derived.
Claims15
A processing arrangement for an oral care device, comprising:
- an input/output;
- and
- one or more processors, adapted to:
- receive at the input/output a sensing signal indicative of a loading force applied to, or motion of, at least one cleaning element of the oral care device, wherein the signal spans a time period, the time period corresponding to a period of mechanical engagement of the at least one cleaning element with at least one tooth during an oral cleaning session,
- process a waveform of the signal to extract one or more characteristics of the signal waveform for the time period;
- obtain a measure of at least one further characteristic, the further characteristic being a characteristic of the tooth, and/or of the mechanical engagement of the at least one cleaning element with the tooth;
- determine a metric of tooth mobility for the at least one tooth in dependence of the one or more signal characteristics and upon the at least one further characteristic;
- and
- generate a data signal GM indicative of the determined metric, and provide the data signal to the input/output.
