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 communication device positioned in the handle and a power source positioned in the handle. The power source powers the at least one motion sensor and the communication device. User profile data is collected from the user. Shave event data associated with the user during a shave is collected from the at least one motion sensor. The shave event data and user profile data is processed to generate user feedback information. The user feedback information is communicated to the user.

A personal appliance. The personal appliance includes a handle having an implement connecting structure. An implement is connected to the implement connecting structure. An implement displacement sensor is associated with the handle. The implement displacement sensor measures a displacement of the implement relative to a fixed position of the handle. A power source, an acceleration sensor and an angular velocity sensor are associated with the handle.

Provided is a manual razor having a temperature-changing function. The handle is provided with the heat transfer structure having both heating and refrigeration functions, or the refrigeration structure only having a refrigeration function, or the heating structure only having a heating function, and the heat transfer structure, the refrigeration structure or the heating structure is directly connected to the blade in a heat conduction mode, so that the temperature of the blade for shaving is changed along with the change of the temperature of the heat transfer structure, the refrigeration structure or the heating structure. Moreover, the razor has few structural components and is low in cost, compact in overall structure, and small in occupied space.

A shaver head comprising a blade assembly having one or more blades for cutting hair in a shaving direction; a skin adaptor extending from an outer periphery of said blade assembly and having a skin adaptor surface configured to be in contact with a shaving surface; a coil assembly, the coil assembly being configured to be transitioned between an active state and an inactive state and to generate an electromagnetic field in the active state. The electromagnetic field can be configured to cause pili muscles in the shaving surface to contract in order to expose hair of the shaving surface so that the hair is cut by the blades of the blade assembly.

A constructive solution where hair removal by thermal dispensing is enabled by the action of accumulators and electric system (4) or by direct supply (6, 7) of electric power converted into thermal power, aiming at the preheating and later heating of a laminar or filamentary conductor (2), upon thermal dispensing by the action of an electrical resistance, conduction by heat transfer, or also conduction or thermal diffusion.

A transferrable vibrating system for use with hand held razors which includes a housing in which is disposed a battery, a switch and a motor driving a vibrating element. The system is easily removed from one hand held razor and attached to another and would be preferably waterproof. One preferred embodiment of the present invention would be preferably waterproof and might include a housing that is completely sealed, preferably buoyant and capable of floating while attached to a razor. Another embodiment of this invention would be preferably waterproof and provided with a rechargeable battery that might be recharged via wireless, inductive charging. Another embodiment would be preferably waterproof and provided with a cap to allow access to a replaceable battery. Another embodiment would be preferably waterproof and provided with a port allowing the direct connection of an external DC power source to a rechargeable battery contained in the housing.

An intelligent shaving system is disclosed herein including a system having 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 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.

Methods and apparatuses for an intelligent shaving system is disclosed herein. An example 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 novel retarding mechanism is shown to reduce the inertia of the battery shell during a linear detachment movement from a handle of an appliance, such as a battery powered razor or shaver. The retarding mechanism is based on the interaction between the battery shell found on a lower portion of a razor handle and a battery carrier found within the upper portion of a razor handle. Specifically, an engagement spring having at least one knob type structure is mounted on an interior surface of the battery shell and axially engages protrusions and/or recesses on an exterior surface of the battery carrier during a detachment movement of the battery shell. During opening or detachment of the shell, the engagement of the knob with protrusions produces a retarding force effect of the shell during the linear detachment.
