Abstract: A shaving system comprises a shaving device and a cleaning device. The shaving device has an orientation sensor for generating an output signal representing the orientation of the shaving device. The cleaning device supports the shaving device in a cleaning position with a predefined cleaning orientation. The cleaning device is controlled to operate according to a predefined cleaning program for cleaning the shaving unit when the orientation sensed by the orientation sensor corresponds to said predefined cleaning orientation. This shaving device thus makes use of an orientation sensor to identify when the shaving device is in a cleaning orientation. This gives a low cost sensing solution and enables a single user input button to be used for operating the shaving device and for starting a cleaning program.

Abstract: A shaving unit and/or electric shaver having a lighting module for providing an optical heating function at a skin-contacting surface of the shaving unit. At least one aspect of the invention relates to an encapsulation arrangement for components of the lighting module by means of a potting material which encapsulates, on both an upper and lower side, a carrier to which lighting elements are mounted.

Abstract: A power adaptor to supply power for a portable device has an input circuit (21) for receiving mains input power, a power switch device (25), a power inductance (24) and an output circuit (22) coupled to the power inductance to provide the supply power for the portable device, and a controller (26) for controlling the power switch device according to a supply power requirement of the portable device. The adaptor has a measurement inductance (27) magnetically coupled to the power inductance, and the controller comprises a measurement input (28) for detecting a measurement signal indicative of a magnetic state of the power inductance. The controller detects the supply power requirement based on the magnetic state in response to a controlling of the power switch device via the controller. Advantageously different portable devices can be supplied by appropriate power.

Abstract: A battery voltage monitoring system monitors voltage of an arrangement of more than two batteries (U1, U2, U3, U4, U5) in series. The system comprises a voltage divider comprises a first (R1, R2, R3, R4) and second resistive element (R5, R6, R7, R8) arranged parallel to at least a part of the battery arrangement and connected to a reference voltage line and to a node (N1, N2, N3, N4) in the battery arrangement. In between the first (R1, R2, R3, R4) and second resistive element (R5, R6, R7, R8) a transistor (Q11, Q12, Q13, Q14) is arranged. The base of the transistor is, via a diode (D1, D2, D3, D4), connected to a further node (N2, N3, N4, N5) in the series arrangement of batteries, and a switching element (Q1, Q2, Q3, Q4) is provided to address the transistor (Q11, Q12, Q13,Q14).

Abstract: A fraction of the battery energy is kept in reserve during operational use of a battery-powered apparatus. The motor of the apparatus is switched off when the battery has discharged to the level of this reserve fraction. The reserve is made available again for operational use when the user has recharged the apparatus for a little while. This approach 5 simulates a super fast charging operation.
