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.

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.

This disclosure presents systems and methods to improve user brushing behavior. Exemplary implementations may: effectuate presentation of audio content via an audio output device, the audio content being characterized by an audio profile; obtain output signals from one or more sensors coupled to a user device, the output signals conveying user input information, the user input information defining user input by a user via the user device; determine, based on the user input information, a user profile, the user profile including one or more user values of the one or more audio attribute; compare the user profile with the audio profile to determine, for individual audio attributes, one or more differences; determine one or more scores reflecting the one or more differences; and/or perform other operations.

An oral care system including an oral care device and a processor. The oral care device includes a head having cleaning elements and a vibrational sensor configured to determine vibrational data emitted by the oral care device in use. The processor is operably coupled to the vibrational sensor and is configured to: determine, based on the vibrational data, an applied pressure of the cleaning elements upon an oral cavity of a user; determine an optimal pressure associated with the oral cavity of the user and a non-optimal pressure associated with the oral cavity of the user; and based on the applied pressure of the cleaning elements upon the oral cavity being substantially the non-optimal pressure, cause the applied pressure of the cleaning elements upon the oral cavity to be substantially the optimal pressure.

The present application discloses an electric toothbrush, which relates to the technical field of toiletries, and specifically comprises a body and a toothbrush head, wherein two through holes are integrally formed at an end of an end cover at the front of the body, and two groups of lamp beads are installed on the inner side of the end cover near the top through the lamp control circuit board. The toothbrush head is composed of a sleeve, a central main rod and a vibrator docking unit as a whole, wherein the central main rod and the vibrator docking unit are all made of PMMA high light-transmitting plastic by integral injection molding. The present application improves the design on the basic structure of the existing split-type electric toothbrush, so that it can realize the disinfection and sterilization of each dead corner of the toothbrush head.

A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.

The present invention relates to the field of battery powered electrical appliances or personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. A control device for a battery powered electrical appliance for personal hygiene is described, wherein the control device is adapted to cause the battery powered electrical appliance to perform automated contact fritting of a battery contact by controlling the battery powered electrical appliance such that a current pulse exceeding a wetting threshold is applied across the battery contact during a standby period.

An optical analysis of saliva or a fluid-saliva mixture is performed in order to check whether the saliva or fluid-saliva mixture contains blood, which allows for determining whether or not a person may suffer from gingivitis or another condition affecting gum health. Light received from a representative volume of fluid (23) containing saliva is detected and analyzed. The analysis involves determination of at least one measurement value of light received by a light-receiving unit (25) for only a single wavelength of the light, particularly a wavelength that is associated with high absorption by a constituent of blood. It this respect, it is practical if the light-receiving unit (25) is configured to receive reflected light back from the volume of fluid (23). The optical analysis may be performed real-time during an action in a person's mouth involving a gum agitation effect, or after such action has taken place, for example.

An apparatus to facilitate makeup blending and application is disclosed. The makeup blender includes a body that provides a steady state vibration and is easily grasped by a human hand. The makeup blender is electrically powered by replaceable batteries or rechargeable batteries. The makeup blender provides for an attachment interface that facilitates easy snap on or off, for attachments such as a brush or a cotton ball holder. The electrically powered consistent vibration on an attachment such as a brush provides for even and smooth blending of makeup over the skin.

A system and method for operating a personal grooming/household appliance, including: providing a personal grooming/household appliance including at least one physical sensor taken from a group consisting of: an orientation sensor, an acceleration sensor, an inertial sensor, a global positioning sensor, a pressure sensor, and a load sensor, audio sensor, humidity sensor, and a temperature sensor; providing a camera associated with the personal grooming/household appliance; classifying data received from the physical sensor and from the camera using at least one trained machine learning classifier to generate an augmented classification; and providing user feedback information based upon the augmented classification or modifying operation of the grooming/household appliance based upon the augmented classification.
