US 11,844,422 B2 · Controllable brush

Abstract

Controllable brush, comprising a bristle carrier (BC) having a plurality of bristles (B), and a supplementary carrier (SC) having a plurality of protrusions (P), a distance (d) between the supplementary carrier (SC) and the bristle carrier (BC) being modifiable, whereby decreasing the distance (d) results in the protrusions (P) being inserted through the bristle carrier (BC). Decreasing the distance (d) results in the protrusions (P) being inserted inside the bristles (B). Alternatively, decreasing the distance (d) results in the protrusions (P) being inserted between the bristles (B). The controllable brush may further comprise an actuator for modifying the distance (d), and a control unit for controlling the actuator in response to a sensor output. The sensor may be arranged for measuring a force experienced by the brush. Alternatively, the sensor may be a camera of a smartphone.
