Patent attributes
A personal grooming appliance has an energy source, an electronic circuit comprising at least one electric load, and a first sensor for providing a first signal indicating a relevant change of a first external condition. The appliance is arranged to stay in a sleep mode in which the electronic circuit consumes at least a reduced average energy amount in comparison to an active mode and to initiate the active mode when the first signal indicating a change of the first external condition is received. The electronic circuit can be arranged to perform a welcome routine in response to a first active mode initialization and a standard routine, different to the welcome routine, in response to receiving the first signal indicating a relevant change in the first external condition after the welcome routine has been performed. The first sensor can be a light sensor, a resistance sensor, a humidity sensor, a gas sensor, or a temperature sensor. A personal grooming appliance unit comprising the personal grooming appliance in combination with a packaging that houses the appliance can include the first sensor that is sensitive to a change of the packaging condition comprising an opening of the packaging.
