A dreadlock grooming device including handle, a cylindrical housing attached to the handle, a power source, and a power control. The cylindrical housing includes a first-semi-arcuate-section and a second-semi-arcuate-section together forming a clamp of the cylindrical housing. The cylindrical housing includes a plurality of serrated blades positioned along an interior surface of the cylindrical housing provided to remove stray hairs from a section of hair within the clamp formed by the first-semi-arcuate-section and the second-semi-arcuate-section during use.

The present disclosure provides a razor accessory with a camera to assist the user of a shaving razor, which razor accessory is configured to be mechanically attached to the shaving razor. The razor accessory may be provided with sensors to track the shaving movements of a user. The present disclosure also provides an application for a wearable computer device to track the shaving movements of a user. The razor accessory and/or the wearable computer is communicatively connected to a vendor platform via an Internet-of-Things (IoT) gateway, which may provide feedback to assist and optimize the user's shaving experience.

A nape hair shaving device for allowing a user to shave hair on a nape located behind the user's neck, comprising an arcuate shaving bar and a plurality of razors projecting therefrom to form a curved shaving arc which conforms to the shape of the user's neck. The user employs the shaving device by grasping the shaving device via a pair of grips with the arcuate shaving bar horizontally positioned therebetween, positioning the shaving arc above the nape, and making a shaving motion by drawing the shaving arc downwardly over the nape to cut the hair growing thereon. The arcuate shaving device is further flexible and is adapted to be bent inwardly or outwardly to selectively vary the size of the shaving arc. The plurality of razors are selectively detachable, allowing dulled razors to be removed and replaced.

A shaving system, comprising a shaver including a handle a cartridge having at least one blade, the cartridge pivotably connected to the handle about a transverse axis of the handle; and a biasing element connected to the handle and connected to the cartridge, the biasing element being configured to move along a longitudinal axis of the handle in response to the cartridge pivoting about; a sensor configured to determine a pivot angle of the shaver cartridge relative to the handle; and a processor configured to receive information about the movement of the biasing element and determine an angle between the cartridge and the handle about the transverse axis based on the information.

A computer-implemented method of determining a location of a personal care device with respect to a skin surface of a subject, the personal care device being configured to perform a personal care treatment to the skin when in contact with the skin surface. The method includes receiving data representative of a measured degree of curvature of the skin surface within a first region of the skin surface of the subject, with which the personal care device is in contact; determining, by comparing the measured degree of curvature with curvature information for a plurality of regions of the skin surface of the subject contained in a database, an indication of a location of the first region of the skin surface on the subject; and performing, based on the determined indication of the location of the first region, an action in respect of the personal care device. A processing apparatus, a system, a personal care device, and a computer program product are also disclosed.

There is provided an apparatus (100) for determining a location of a personal care device on a user. The apparatus (100) comprises a processor (102) configured to detect a location of one or more parts of the body of a user, detect motions of at least one of the parts of the body of the user induced by the personal care device when the personal care device is in use and determine the location of the personal care device on the user based on the detected motions of the at least one part of the body of the user in relation to the detected location of the at least one part of the body of the user. The processor (102) is configured to acquire images of the user from an imaging sensor (108) directed at the user, and detect the location of the one or more parts of the body of a user and the motions of the at least one part of the body of the user induced by the personal care device from the acquired images of the user.

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 razor having a handle and blade cartridge containing one or more blades includes a battery power source and a heating system powered by the battery source for heating the one or more blades and/or a heating element on the blade cartridge. The blade cartridge further includes a strip of lubricating material thereon that is heated by the heating system when the blades and/or heating element warm up. As the strip of lubricating material is warmed up, it provides a release of extra lubricating chemicals, including fats or other lubricating agents. This helps to provide a more comfortable shave while also protecting the user's skin both during shaving and after shaving.

Razor having a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member. Each sawing tooth has a tooth tip and tooth edges mutually connected via the tooth tip. The hair-severing member is mounted for sawing through hairs present on the skin by means of the sawing teeth by moving each sawing tooth in a local direction of extension of the hair-severing edge at the position of the respective sawing tooth. A drive is coupled to the hair-severing member for driving the hair-severing member such that the sawing teeth move with an average velocity larger than or equal to 10 m/s. The spacing between the tooth tips of two successive sawing teeth is between 20 μm and 150 μm.

The invention relates to a razor and a method for producing a razor. In order to provide an improved razor, a razor (1) has a handle (10), at one end of which a ball joint socket (11) is arranged, and a blade head (20) having at least one razor blade (21) and a ball joint head (22). The ball joint head of the blade head and the ball joint socket of the handle form a ball joint, and the handle has an alignment element (14) in the ball joint socket that is designed to engage with a recess (36) in the ball joint head.
