Shaving assemblies are disclosed that include a blade unit, an interface element configured to connect the blade unit to a handle, on which the blade unit is pivotably mounted, and a return element disposed between the blade unit and interface element. The return element serves as interface piece, connector and pivot all in one. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

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.

A system for classifying the usage of a handheld consumer device having a sensor and an analyzer. The sensor determines usage data at successive time instants and provides a temporally successive sequence of usage data during a usage session. The analyzer classifies the usage of the device with respect to at least one set usage classes and assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples having at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network arranged to output at least one output tuple comprising a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer device at the given time instant relates to a respective usage class.

The present application relates to a system and a method for treating a part of a body to be treated, particularly a system and a method for cutting hair on a part of a body to be treated. The system has a hand-held treating device having a treating unit, and an imaging module configured to generate information indicative of the position of the treating device relative to the part of the body to be treated based on an image of a part of the body and the treating device. The system also has a guide face configured to space the treating unit from the part of the body to be treated during use of the system. A controller is configured to change a distance between the treating unit and the guide face in dependence on the information generated by the imaging module.

A cutting apparatus for hair or fiber protruding from a surface includes a roller, a number of cutting features disposed at an outer peripheral surface of the roller, wherein the number of cutting features is adapted for cutting the hair or fiber when the roller rotates in contact with the filamentous surface or is moved while in contact with the filamentous surface.

A hair cutter has a base comb with a plurality of base teeth and a supporting comb spaced from said base comb having a plurality of elongated supporting teeth extending to a lesser extent than the base teeth. A cutter blade, which may be adjustable, is secured on the supporting comb side of the base comb in spaced relationship with respect to the base comb with a cutting edge extending in the first direction to a greater extent than the supporting teeth, but to a lesser extent than the base teeth. The hair cutter is structured to have the base teeth and support teeth engaging a portion of the body with progressive movement of the hair cutter serving to effect cutting of the hair to the desired length. The cutter blade may be caused to vibrate by a suitable vibrating motor energized by a battery.

A shaving and grooming apparatus includes a handle and a cartridge attached to the handle. A plurality of upper blades are positioned in the cartridge, where at least some of the plurality of upper blades include curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during use. A plurality of lower blades is positioned adjacent to the plurality of upper blades in the cartridge, where at least some of the plurality of lower blades comprises curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during cutting. At least one of the plurality of upper and the plurality of lower blades has a thickness and flexibility that results in deflection during cutting that increases effectiveness of cutting action. A drive motor moves the plurality of upper blades relative to the plurality of lower blades.

A hair length mapping or cutting device uses multiple comb elements to capture bunches of hair as it is traversed across a scalp. The comb elements are traversed away from the scalp to individually measure or cut each bunch of hair to length. Hair may be cut to conform to a hair style mapped, for instance, from an earlier measurement of a hair style.

Various embodiments of a system for cutting hair are described herein. The hair cutting system includes a user interface, a positioning mechanism, a securing mechanism, and a cutting mechanism. The power source is configured to supply electrical power while the user interface includes a data receiving unit for receiving data related to a head of a user, and a display is configured to input data and/or display data. The cutting mechanism is electrically coupled to the power source for cutting the hair on the head of the user. The positioning mechanism is for positioning the cutting mechanism relative to the head of the user, and the securing mechanism for supporting the positioning mechanism. Related apparatus and methods are also described.

Shaving assemblies are disclosed that include a blade unit, an interface element configured to connect the blade unit to a handle, on which the blade unit is pivotably mounted, and a return element disposed between the blade unit and interface element. The return element serves as interface piece, connector and pivot all in one. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.
