Provided is a razor assembly including a cartridge including at least one blade and a handle assembly including an electric power source, a printed circuit board (PCB) electrically coupled to the electric power source, and at least one induction coil coupled to the PCB, wherein the at least one induction coil is configured to cause at least a portion of the cartridge to be heated in a non-contact manner, wherein the cartridge is detachably coupled to the handle assembly.

A shaving system comprising a handle, a cartridge including at least one blade, the cartridge being releasably coupled to the handle, a detector, at least one sensor coupled to at least one of the handle and the cartridge, wherein the at least one sensor is configured to output an electrical signal in response to an infrared thermal radiation, detected and measured by the detector, of at least one skin property which is indicative of at least one skin characteristic, a processor configured to receive measurement data from the sensor and to at least one of identify and quantify the at least one skin characteristic based one the received measurement data, and a display configured to convey a message to the user based on skin characteristic data from the processor.

A shaving razor having independent blade assemblies coupled to substantially rigid linkages. The linkages each defining a pivot point that permits reciprocating motion of the blade assemblies where assemblies on opposite sides of the pivot point reciprocate in opposite directions. Other embodiments are also described and claimed.

An intelligent shaving system includes a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.

A handle for an electrically operated personal-care implement includes a metal tube housing having a metal wall with an opening and an inner surface, the inner surface defining an inner cavity of the housing for accommodating an energy source, and a switch assembly for activating the energy source. The switch assembly, including a hard switch component and a soft switch component, is arranged in the opening and seals the opening from the inner surface of the wall. The hard switch component comprises a frame having a recess and attached to the inner surface of the metal wall thereby surrounding the opening and providing an undercut between the recess and the inner surface. The undercut is open to the opening, and the soft switch component is positioned in the undercut to at least partially cover the opening.

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.

A method for generating user feedback information from a shave event associated with a user. A shaving razor is provided to user. The shaving razor includes a handle, a hair cutting implement connected to the handle, at least one motion sensor in the handle, a hair cutting implement displacement sensor positioned in the handle, a communication device positioned in the handle and a power source positioned in the handle. The power source powers the at least one motion sensor, the hair cutting implement displacement sensor and the communication device. Shave event data associated with the user during a shave is collected from the at least one motion sensor and the hair cutting implement displacement sensor. The shave event data is processed to generate user feedback information.

Provided is a razor assembly including a cartridge including at least one blade and a handle assembly including an electric power source, a printed circuit board (PCB) electrically coupled to the electric power source, and at least one induction coil coupled to the PCB, wherein the at least one induction coil is configured to cause at least a portion of the cartridge to be heated in a non-contact manner, wherein the cartridge is detachably coupled to the handle assembly.

A shaver is disclosed and includes a handle with a plurality of razor-heads attached to a plurality of arms. The razor-heads being adjustable to accommodate shaving areas of different shapes and sizes. The razor-heads provide versatile maneuverability by incorporating movement about at least two distinct axes for each razor-head. Each razor-heads' maneuverable range functions independent of any additional razor-heads.

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.
