A method for operating a vehicle treatment system, in particular a vehicle washing system, includes treating at least one vehicle surface with at least one rotating brush with a brush material at an immersion depth of the brush, and controlling during the treatment of the vehicle surface, the rotating brush based on a setpoint value for the friction of the brush material on the vehicle surface, the immersion depth of the rotating brush on the vehicle surfaces treated therewith being monitored at the setpoint value during the treatment of the vehicle surface in order to determine the state of the brush material. In addition, a vehicle treatment apparatus, a use thereof, and a computer program product are provided.

The present invention, a cylindrical rotary tire brush element with an integrated wear indicator, is intended to replace the prior art cylindrical rotary tire brush element in a prior art rotary tire brush assembly. The cylindrical rotary tire brush element with integrated wear indicator is intended as a drop-in replacement to the prior art cylindrical rotary tire brush element of a prior art rotary tire brush assembly. The invention is made from at least two homogeneous pluralities of bristles, with each homogeneous plurality of bristles having the same purpose, material, color, and specified length. At least one plurality is a cleaning bristle of a first color and first specified length. At least one plurality is an indicator bristle of a second color and a third specified length, where the second color is a highly noticeable color such as yellow, red, orange, green, or white. The third specified length is equal to the minimum acceptable actual length of the cleaning bristles.

The invention relates generally to the field of medical devices and, more specifically, to a handheld device that stimulates the meibomian gland of the eyelid mechanically, and specifically stimulates the meibomian glands of the eyelid to treat Meibomian gland dysfunction, also known as Dry eye and chronic marginal eyelid inflammation.

A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. The number of colored filaments comprise at least a first type of filament having time-controlled color changing properties and a second type of filament having time-controlled color changing properties, so that each of the first and second type of filament changes its color from an initial color to a second color within a pre-defined time period. The initial color of the first type of filament is different from the initial color of the second type of filament. The second color of the first type of filament and the second color of the second type of filament are substantially the same, preferably substantially white, grey and/or translucent. The second color of the first and second type of filament define a second color pattern. The initial color pattern changes to the second color pattern after the head is used over about 240 minutes to about 360 minutes, by applying a brushing force from about 0.5 N to about 2.5 N.

A surface conditioning article is presented that includes a hub portion with a first material. The first material is free of abrasive particles. The article also includes a plurality of elongate abrasive elements, each extending along an element axis, and each of the primary elongate abrasive elements includes a second material.

The present disclosure relates to a control method of an electric toothbrush, an apparatus, an electronic device, and a storage medium, including: determining real-time monitoring data during a brushing process of a target user based on the electric toothbrush, and transmitting the real-time monitoring data to a base corresponding to the electric toothbrush based on a wireless communication network, wherein the real-time monitoring data is used to reflect a movement condition of a brush head of the electric toothbrush, and the base is configured to place the electric toothbrush and to charge the electric toothbrush; and determining the reminding message displayed on the base according to the real-time monitoring data, wherein the reminding message is used to indicate a cleanliness degree corresponding to each dental region of the target user.
