Abstract: A personal care device drive unit comprises a main body housing a motor and enabling releasable connection to any selected one of a set of different functional units. A controller of the personal care device drive unit generates an output signal associated with the selected one of the functional units connected to the main body in dependence on a sensed motor current and a sensed vibration occurring in the main body. The use of both vibration sensing and current sensing (which detects the electrical motor load resulting from driving the selected one of the functional units connected to the main body) enables multiple different functional units to be identified more reliably.

Abstract: A shaving apparatus, shaving head and/or at least one cutting unit for shaving both short and long hairs. The shaving apparatus, shaving head and/or at least one cutting unit includes an external cutting member and an internal cutting member movably arranged with respect to the external cutting member. A driver may be provided for moving the internal cutting member. The external cutting member is provided with a shaving section having two mutually connected lateral borders forming hair entry apertures. The internal cutting member is provided with cutting elements having cutting edges for cooperation with cutting edges of the external cutting member. A number of the hair entry apertures are formed by two substantially flat lamellae of the external cutting member which have free ends positioned between the borders of the shaving section.

Abstract: A shaving unit has at least one cutter (10, 12) for cutting hairs (11), a guide surface (4) extending closely adjacent the cutter or cutters (10, 12), and hair guides (3) projecting from the guide surface (4). The hair guides (3) bound channels (5) extending from an area spaced from the cutter or cutters (10, 12) towards the cutter or cutters (10, 12), and the hair guides each have a skin contact surface (6) facing away from the guide surface (4) and a surface (16) facing the guide surface (4), wherein the skin contact surface (6) is at least partially round and meets the surface (16) facing the guide surface (4) along a hair catching edge (7).

Abstract: A shaving apparatus having at least one cutting unit (5) is provided which is able to shave both short and rather long hairs. The cutting unit comprises an external cutting member (7) and an internal cutting member (9) movably arranged with respect to the external cutting member, and a driver (11) for moving the internal cutting member. The external cutting member is provided with a shaving section (13) having two mutually connected lateral borders (15, 17) between which hair entry apertures with cutting edges (23) are provided. The internal cutting member is provided with cutting elements (25) having cutting edges (27) for cooperation with the cutting edges of the external cutting member. A number of the hair entry apertures is formed by laterally open recesses (21) each extending between two substantially flat lamellae (29) of the external cutting member, which lamellae have free ends (29a, 29b) positioned between the borders of the shaving section.
