Abstract: A rotatable body brush, preferably driven by an electric motor, has pivoted segments in the brush or working element. The segments swing outwardly when the user desires a larger-diameter brush, and can be retained inwardly when a smaller brush, such as a face brush, is desired.

Abstract: In one example, we describe a method and system for toothbrush sterilization and/or storage with better quality in terms of hygiene and convenience, where the brush head and the shaft that enter the user's mouth are never contacted by the chamber. Also, below the brush head and shaft, there is no chamber. If any drops of water were to fall off the brush head, they would fall all the way through the chamber and reside on the counter on which the chamber rests, which can be removed or cleaned easily later. In one example, we use a UV-C lamp as our sterilization technique. This selection has many advantages over the other sterilizations techniques. In one example, we use a single lamp, but that lamp is in a ring configuration (otherwise known as annular, torus, or donut), with good coverage of the toothbrush, from all angles.

Abstract: In one example, we describe a method and system for facial brush or body brush, for cleaning the skin. In one example, it utilizes distinct parts: a powered facial brush handle with the ability of offering both an oscillating and rotary setting, removable brush heads of varying materials and compositions, and a charging base station with a protective germicidal UVC sanitizing and drying chamber. User convenience is also central to our solution. All the functional actions of the protective germicidal UVC sanitizing and heating chamber are activated once the brush handle and brush head is placed within it, in one example. Mode control allows the user to choose the right setting for them, offering a mild setting for sensitive skin and normal for balanced skin types. A set duration of brush activation allows the user to orchestrate a complete cleaning. Various examples and variations are presented.
