An oral cleaning device comprises a body which carries a set of projections. An actuator device is associated with one or more of the projections in the form of an electroactive polymer structure for adjusting a position of the associated one or more projections. This enables dynamic control of the cleaning function.

The present invention relates to a brush assembly for cleaning metal, the assembly comprising one or more brush heads, each brush head comprising a bundle of conductive filaments, having a working end adapted for contacting metal, and a terminal end, the brush head connectable to an electricity supply, and a housing connected to and retaining at least one sheath, each sheath at least partially surrounding at least one brush head, wherein each brush head and its respective sheath are movable in relation to each other by operating an adjustment mechanism and the working end of the brush head and the sheath are selectively fixable in relation to each other.

A hair styling apparatus is provided including a brush head, a plurality of tines located on the brush head, and a series of movable linearly arranged prongs having an angled orientation with respect to the brush head. A user causing movement of the linearly arranged prongs serves to secure the user' s hair against a subset of the plurality of tines.

The bristles of this toothbrush design is made of flexible material, the bristle component is not fully attached to the tooth brush handle. Beneath the bristle component is a wire/lever actuator mechanism that could be either pushed or pulled, via an attachment of the wire or lever to a button on the handle of the toothbrush. When pushed or pulled depending on where the wire is attached to the flexible membrane, it will become semi oval or half circle shape. When the user is done and the button is released because of the flexible material used in the construction of the membrane, stored kinetic energy and will return the button to its neutral position. And the membrane to its normal flat or slightly curved position so the toothbrush could be used as a traditional toothbrush design.

A computer-implemented method of training a user to effectively apply makeup using a computerized makeup brush, the method comprising the steps of receiving, from a makeup brush movement tracking system that comprises one or more sensors for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup brush to the particular portion of the user's body, and using the data to generate and display, to a user, a visual representation of the movement of the makeup brush over the particular period of time on a suitable display (e.g., while providing appropriate visual or audio feedback on the user's performance in applying makeup and/or proper makeup application techniques).

The head of the toothbrush, rotating on its axis 180 degrees and 90 degrees to each side. A button is placed in the handle of the toothbrush with is connected to a lever, when the button is moved forward or backwards, it will apply force to the rotating pin. This is done by either using a gear system or simply attaching the lever to the side of the pin in order to transfer kinetic energy. The top of the rotating pin is attached to the part of the toothbrush that holds the bristles, which through rotating pushing or pulling the button can rotate the bristles 90 degrees each side or 180 degrees total. The bristle components can be composed of flexible material. This bristle part can be replaced or changed. Shorter, longer, wider, narrow, soft and harder bristle attachments can be used, based on the individual's needs.

The present invention relates to a broom, and in particular to a multifunctional broom with a rotatable head. According to the present invention, an brush head and a rake tooth are provided on a broom head. The rake tooth can be used for cleaning of regions such as outdoor grounds and lawns, and the brush head can be used for indoor cleaning. Moreover, the rake tooth can be extended out of or retracted into the broom head through the first telescopic mechanism. The broom of the present invention is very simple and convenient to use and provides more thorough cleaning. The first telescopic mechanism enables automatic telescoping depending on various conditions of ground, thereby providing more thorough cleaning and being more convenient and efficient (FIG. 1).
