Brush for cosmetic products made of plastic material of the type apt to engage with an applicator rod including a central core having a substantially cylindrical shape carrying at the end a dome-shaped radiussed appendix and of the combination of various series of teeth mutually equidistant in a longitudinal direction, characterised in that the teeth have a grain-shaped section, which furthermore has two opposite edge lines in correspondence of the extreme points of the major axis.

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.

Disclosed is a hand-held dish cleaning brush that includes an elongate handle with a scrubbing head at one end, the scrubbing head including a working part of an elastomer integrally formed with a plurality of bristles and with a plurality of scraping projections that are formed as an array of scraping teeth, wherein the bristles are not directly aligned with but off-set from the scraping teeth and pass between the scraping teeth when flexed forwardly or rearwardly toward the scraping teeth.

A golf brush with ramp housing is an apparatus intended to clean golf clubs in a user-friendly and versatile manner. To accomplish this, the apparatus includes a ramp shaped housing with a plurality of bristles. More specifically, the apparatus is a golf brush that may be fixed on the ground, hung up on a golf bag, or handheld, according to the user's preference. To that end, the golf brush includes a stepping platform with at least one gripping groove on which the user may step on while pulling a clubface upward across a plurality of bristles. Further, the golf brush includes a fastener port that provides versatility and ease of use and transportation. Furthermore, the ramp housing comprises a plurality of stabilizers, a wedge channel and a plurality of finger grooves for user-friendly and safe operation of the golf brush.

Cleaning system including a brush assembly for cleaning solar panels. The brush assembly has at least one rotatable brush having a rotational axis. The rotatable brush includes a plurality of sets of bristles, each extending outwardly from a core. A shaft extends through the core of the brush. The shaft is a telescoping shaft, which is configured to retract and expand to create an elongated brush assembly. An apparatus, system, and method for conveying an assembly along a track. A rail includes a first planar side, a second planar side, and a third planar side. The first, second and third planar sides are arranged to form at least two acute angles ranging between 50 degrees and 80 degrees. A carriage assembly includes a drive wheel and at least two rollers. The drive wheel is configured to contact the second planar side and is configured to translate the assembly along the rail. The two rollers are configured to contact the two other sides to maintain the carriage in contact with the rail.

The present invention includes improvements to a device with bristles that makes it possible to perform oral hygiene tasks to remove quickly impurities in the oral cavity, in particular when the user is travelling and does not carry a toothbrush and, due to time constraints, requires quick and effective cleaning. The cleaning device may also include luffa sponges, water-soluble films, spheres with toothpaste or channels that provide flexibility to a membrane which, when bending, generates a vacuum and is placed on the tongue in order to be used as a toothbrush handle. The device provides a better fitting and handling in the mouth of a user, since it avoids the generation of vacuum when actuated, and also has a membrane surrounded by a cylindrical section that allows its handling since it adapts to the tongue.

A hair brush with a slideable brush head that allows the brush head to be positioned on either end of the elongated handle to thereby providing ease of use by both right handed or left handed users. The elongated handle arrests the brush head in any desired position via the use of activating flanges that depress an activating rod held in place with compression springs with a cam and arresting balls in the center of the handle. When the activating rod is depressed, the cam is displaced by the compression springs which in turn releases the arresting balls creating a smooth surface of travel for the brush head therealong. The brush head may also be removed from the handle, if so desired, so that a brush head of a different circumference but the same inner diameter may be used. The handle is streamlined and elliptical in shape and contains rubber cushions for easier grip.

Applicator (2) for applying a cosmetic, makeup or care product (P) to the eyelashes and/or eyebrows, having a moulded applicator member (8) having: a core (10) that extends along a longitudinal axis (X), spikes (18) carried by the core (10), and reinforcing sails (1.3) for the spikes (18), which are connected by their base to the core (10). extend parallel to the longitudinal axis (X) of the core (10) and are disposed in a plurality of longitudinal rows (17, 19, 20), at least one first longitudinal row (17) being offset axially with respect to a second longitudinal row (19).

A toothbrush head and a method for brushing teeth. The toothbrush head includes a first brushing portion, and a second brushing portion. A first orientation of the toothbrush head includes the first brushing portion contacting an inside of at least one upper tooth and the second brushing portion contacting an outside of at least one lower tooth. A second orientation of the toothbrush head includes the first brushing portion contacting an inside of at least one lower tooth and the second brushing portion contacting an outside of at least one upper tooth. The method includes steps as follows: a) contacting, with a toothbrush head, an inside of at least one upper tooth concurrently with an outside of at least one lower tooth; and b) contacting, with the toothbrush head, an inside of at least one lower tooth concurrently an outside of at least one upper tooth.

A cleaning robot includes a detector configured to detect an obstacle; a determining portion configured to determine whether the cleaning robot is in an obstacle obstruction state; and a controller configured to control the first drive wheel to cross an obstacle and control the second drive wheel to cross the obstacle according to a detection result when the cleaning robot is in the obstacle obstruction state.
