A system for determining a level of debris accumulation in a region adjacent to at least one blade of a razor cartridge. The system includes a sensing unit to detect a measurement parameter which is one of an amount of light reflected from at least one area adjacent to the at least one blade, and an image of the at least one area adjacent to the at least one blade. A processing unit compares the detected measurement parameter to at least one reference threshold parameter and determines a level of debris accumulation in the at least one area adjacent to the at least one blade based on an amount of deviation of the detected measurement parameter from the at least one reference threshold parameter. Information regarding the determined level of debris accumulation is provided by at least one of a light indication, an aural indication, and a haptic indication.

A system and method for determining a level of wear of at least one blade of a razor cartridge, which includes a sensing unit measures an electrical parameter including one of (i) a total resistance of the at least one blade measured across a length of the at least one blade, and (ii) an electrical conductance of the at least one blade measured across the length of the at least one blade. A processing unit compares the measured electrical parameter to a reference electrical parameter and determines a level of wear of the at least one blade based on an amount of deviation of the measured electrical parameter from the reference electrical parameter. Information regarding the determined level of wear of the at least one blade is provided to a user by at least one of (i) a light indication, (ii) an aural indication, and (iii) a haptic indication.

A razor includes a blade cartridge with multiple blades that removably and pivotally attaches to a handle. The blade cartridge and handle include electronic processing elements for collecting, receiving, processing, storing and transferring data before, during and after use of the razor for shaving. A charging base allows for charging a rechargeable power source in the handle and is further adapted to communicate with a smartphone, computer or other electronic device via wired and/or wireless communication. The processing elements in the blade cartridge and the handle bidirectionally communicate with each other and the charging base including sending and receiving the data therebetween.

A networked shaving appliance system includes: (a) a shaving appliance including a handle and a shaving head cartridge connected to the handle and motion, orientation, and/or pressure sensors associated with the handle and/or shaving head cartridge; (b) a sensor circuit connected to receive sensor signals and generate shave event information from the sensor signals; (c) a network circuit wirelessly connected with a computer network and communicating at least the shave event information to the computer network; and (d) a computerized tool operating, at least in part, on a computerized user device connected to the computer network. The computerized tool is configured to receive shave event data associated with a user of the computerized device from the computer network, receive user profile data from the user via a graphical user interface provided by the computerized tool, process the shave event data with the user profile data to generate user feedback information, and communicate the user feedback information to the user via the graphical user interface provided by the computerized tool.

A grooming device including a handle and a grooming implement connected to the handle. The handle includes a first portion having a housing, a proximal end and a distal end. A displacement sensor is positioned within the housing. A power source is positioned within the housing with the power source providing power to the displacement sensor. A neck portion is pivotably connected to the proximal end of the first portion about a handle pivot axis. The neck portion includes a proximal end, a distal end and a location element. As the neck portion pivots about the handle pivot axis relative to the first portion the displacement sensor detects displacement of the location element.

In a first aspect, the present disclosure relates to a shaving head comprising: a housing, one or more cutting members, comprising a base portion and a blade mounting portion connected to the base portion and extending at an angle therefrom, wherein a blade with a cutting edge portion is connected to the blade mounting portion, one or more base parts configured to hold one cutting member and to couple it to the housing, wherein the base portion is arranged in the one or more base parts rotatably around an axis of rotation extending in parallel to the cutting edge portion, and wherein the one or more base parts comprise an actuator which is configured to rotate the cutting member around the axis of rotation thereby varying a shaving angle of the blade, wherein the shaving angle is an angle between a blade and shaving plane of the shaving head.

A trimming assembly for dreadlocks comprises a handle. A cutting head is operatively connected to the handle. The cutting head comprises a cutting head body defining a receptacle at a radial end thereof. The receptacle is structured to receive a dreadlock. A blade protector is positioned axially within the receptacle. A curvature of the blade protector corresponds to a curvature of an inner wall of the receptacle. A blade is interposed between the blade protector and the inner wall. The blade defines a cutting edge at an axial end thereof proximate to the handle. The cutting edge is structured to cut loose hair protruding outwards from the dreadlock as the cutting head is moved along the dreadlock.

According to a first aspect, a razor head is provided. The razor head comprises one or more cutting members, one or more resilient elements, wherein a resilient element of the one or more resilient elements is connected with a respective cutting member from the one or more cutting members and wherein at least one resilient element of the one or more resilient elements is configured to transduce vibrations from the respective cutting member of the one or more cutting members into an electrical signal corresponding to the vibrations when the razor head is used by a user.

A shaving razor having at least two independent blade assemblies coupled to substantially rigid linkages. The linkages each defining a pivot point between the two independent blade assemblies. A bridge spans between the linkages such that movement of the bridge causes pivoting about the pivot point enabling reciprocating motion of the blade assemblies where assemblies on opposite sides of the pivot point reciprocate in opposite directions.

A shaving razor system with a handle and a shaving razor cartridge mounted to the handle. A flexible electrical bridge with a portion positioned within the handle extends from the handle to the shaving razor cartridge. The flexible electrical bridge has a loop between the shaving razor cartridge and the handle.
