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.

A guard element (4) for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base (10) and an annular wall (20) comprising a main part (21) extending from the periphery of the base (10), and a flange-shaped part (22) comprising an outwardly bent section (24). The annular wall (20) is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part (22) has a diameter which is smaller than a diameter of a largest inner periphery of a straight section (23) of the main part (21) connected to the periphery of the base (10), and a design where a free end section (25) of the flange-shaped part (22) is at least partially bent. In an embodiment, at least a portion of the main wall part (21) of the guard element (4) tapers inwardly in a direction along a central axis (11) of the disc-shaped base (10), from the disc-shaped base (10) to the flange-shaped wall part (22), such that the flange-shaped wall part (22) is enlarged with respect to a flange-shaped wall part (22) of a guard element (5) not having the tapered shape of the main wall part (21), resulting in increased stiffness and an increased resonant frequency of the guard element (4).

An oral hygiene device for use with a wireless network is disclosed. The device comprising a toothbrush for brushing teeth surface; a sensor for generating an output in response to a physical phenomenon; an first antenna for coupling to the wireless network using Radio-Frequency (RF) waves; a first wireless transceiver coupled between the first antenna and the sensor for transmitting a first data that is responsive to the sensor output over the wireless network; a rechargeable battery for powering the sensor, the toothbrush, and the first wireless transceiver; and an handheld casing housing the rechargeable battery, the toothbrush, the sensor, the first antenna, and the first wireless transceiver. The wireless network may be a Wireless Personal Area Network (WPAN) such as Bluetooth, or may be a Wireless Local Area Network (WLAN) such as WiFi (IEEE 802.11).

A personal care appliance comprises a head, a display device, and a drive unit including a motor for driving a removable tool element in the head via a drive transmitter. The head has at least one coupling element for coupling different types of tool elements with the drive transmitter. The tool elements comprises at least two of the following tool elements: a skincare unit, a long-hair cutting unit, a beard-trimming unit, a brush, and a short-hair cutting unit, wherein at least one mode button is provided for changing operating parameters of the motor and is configured to indicate upon activation at least one of the tool elements at the display device.
