In certain embodiments, a pet brush includes a body having a first retractable deshedding blade, a second retractable deshedding blade, a deshedding brush, and a cleaning surface. The pet brush further includes a handle and a cover.

A method (500) for localizing gingival inflammation using an oral care device (10), the method comprising: (i) emitting (520) light at a first intensity by a light emitter (42); (ii) obtaining (530) first reflectance measurements reflectance data; (iii) determining (540), by a controller (30) from the first reflectance data, whether the location comprises gingiva; (iv) automatically adjusting (550), based at least in part on the first reflectance data, the intensity of a light emitter to a second intensity different from the first intensity, and/or automatically adjusting (550) a gain of a light detector; (v) obtaining (560) a second plurality of reflectance measurements by the light detector of the oral care device for at least some of the locations; and (vi) determining (570), using the second plurality of reflectance measurements, whether gingiva at the location is inflamed.

A hair styling device comprises a hair brush portion and an air mover portion comprising a heating element and a fan. The hair brush portion comprises a hollow brush head. The hollow brush head comprises bristles and apertures to allow air to exit the brush head in the region of the bristles. The brush head comprises at least one baffle arranged within the hollow brush head and extending radially inwardly from an inner wall thereof so as to peel off air from the periphery of the flow through the hollow brush head and direct it through the apertures.

An aqueous solution for intraoral cleaning via irradiation with ultraviolet ray and/or near-ultraviolet visible ray and/or ray in an 800-900 nm near-infrared region is employed as the hydrogen peroxide aqueous solution, wherein a concentration of hydrogen peroxide is 1 w/v % to 7 w/v %, and a concentration of a hydrogen peroxide stabilizer is 81 ppm (mg/L) or less in the aqueous solution.

End effectors and systems including end effectors including embedded batteries and auxiliary components powered by the batteries are described. In an example, the end effector includes a base portion coupleable to a motor carried by an appliance that is separate from the end effector; and a battery disposed in the base portion configured to power an auxiliary component of the end effector.

The present invention discloses an electric pet hair brush. The electric pet hair brush. comprises a shell, a roller, a control module and a power module. The shell has an accommodation space. The control module and the power module are electrically connected and are accommodated in the accommodation space. The roller is arranged at the front end of the shelf and is connected with the power module. The roller can be driven by the power module to rotate. The roller comprises a roller main body and multiple comb assemblies. The power module drives the roller main body to rotate, and the multiple comb assemblies can alternatively and circularly extend from the roller main body or retract into an accommodation space of the roller main body with the rotation of the roller main body.

A dental device tracking method including acquiring, using an imager of a dental device, at least a first image which includes an image of at least one user body portion outside of a user’s oral cavity; identifying the at least one user body portion in the first image; and determining, using the at least the first image, a position of the dental device with respect to the at least one user body portion.

Systems, devices, and methods for in situ diagnostic assessment and formula dispensing are described. A diagnostic formula applicator can include a fluid dispensing assembly coupled with a comb having a plurality of tines. A tine of the plurality of tines can be configured to dispense a fluid formula to a region of a biological surface via at least one fluid conduit. The diagnostic formula applicator can include hair diagnostic circuitry operably coupled to the fluid dispensing assembly. The diagnostic circuitry can be configured to actuate the fluid dispensing assembly to deliver the fluid formula via the at least one fluid conduit, responsive to determining a user-specific hair cosmetic aspect from hair and scalp sensor information.
