  • Patent number: 8561301
    Abstract: Razor handles are provided for razors having a battery-powered functionality. Methods of manufacturing such handles are also provided. In one implementation, the handle comprises: a load comprising a motor coupled to a power source; a user-operable switch for controlling energy flow between the power source and the load; a control logic; an arming circuit to prevent the user-operable switch from causing drainage of the power source; and a locking circuit that receives a switch signal from the user-operable switch and an arming signal from the arming circuit, wherein the locking circuit outputs a motor control signal to the control logic in response to the states of the switch signal and the arming signal, wherein the arming circuit comprises a timer for changing the state following lapse of a time interval and an arming switch having a first state and a second state.

  • Patent number: 8555510
    Abstract: The invention relates to an electrically driven razor and an associated charging station, wherein at least one drivable cutting or shearing part is supported on a shearing head disposed on the razor housing and wherein at least one active thermocouple that can be electrically actuated is thermally coupled to a passive cooling element on the side that can be cooled relative to the ambient temperature. The passive cooing element in this arrangement is disposed having at least one free end section on or in the region of the shearing head, such that it contacts the skin of a user in shaving mode.
