System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

The present invention is directed to a hair cutting apparatus (600), such as a shaver, which comprises a cutting detector to actually detect any hair-cutting actions of the hair cutting apparatus. The apparatus further comprises a cutting indicator having a light indicator (620) configured and controlled by the cutting detector to be instantaneously activated when the cutting detector actually detects a hair-cutting action.

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 positioned in 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 positioned in the handle.

A cutter head for use with automated hair cutting systems are provided. The cutter head comprises a coupling apparatus for attaching the cutter head to an automated hair cutting device; a top comb comprising a plurality of top cutting members; a bottom comb comprising a plurality of bottom cutting members; and a control apparatus having a plurality of control modes for controlling movement of the top and bottom cutting members.

The present invention relates to a hair clipping device (10) comprising: a housing (14), a cutting assembly (16) for clipping hairs, a comb attachment (12) which is attachable to the housing (14), a drive unit (38) for moving the comb attachment (12) relative to the cutting assembly (16) between different comb positions in order to set a hair cut-length, a control unit (36) for controlling the drive unit (38), a memory unit (40), and a user interface (34). The user interface (34) is configured to receive from a user a first memory input indicative of a first comb position and to send a first memory signal to the control unit (36) in response to receiving the first memory input, and wherein the user interface (34) is configured to receive from the user a first recall input indicative of the first comb position and to send a first recall signal to the control unit (36) in response to receiving the first recall input, wherein the control unit (36) is configured to store position information regarding the first comb position in the memory unit (40) in response to receiving the first memory signal, and wherein the control unit (36) is configured to recall the position information regarding the first comb position from the memory unit (40) in response to receiving the first recall signal and to control the drive unit (38) to move the comb attachment (12) to the first comb position according to the position information regarding the first comb position.

There is provided a method of providing feedback regarding motion of a rotary shaver performed by a user, the method comprising the steps of receiving, during at least one time interval, at least one motion type determined for the motion of the rotary shaver performed by the user, wherein the motion type is selected from a set of predefined motion types that comprises small rotational motion and one or more other predefined motion types; determining a degree of occurrence in the time interval of each of the motion types in the set of time interval; determining from the determined degree of occurrence of each of the motion types in the set of predefined motion types which motion type has a highest degree of occurrence in the time interval; and providing feedback to the user to increase a degree of occurrence of small rotational motion of the rotary shaver if the determined motion type having the highest degree of occurrence is one of the other predefined motion types.

A system for determining an orientation of a first device relative to a user includes a first device including a first orientation measuring unit configured to measure an orientation of the first device relative to the earth, a second device configured to be worn by the user on a body part. The second device includes a second orientation measuring unit configured to measure an orientation of the second device relative to the earth. The system also has a processor configured to calculate an orientation of the first device relative to the second device by comparing the measured orientation of the first device relative to the earth with the measured orientation of the second device relative to the earth.
