  • Patent number: 10555591
    Abstract: There is provided an epilation device for removing body hair with at least one epilation unit. In particular, an epilation barrel, having a plurality of pairs of tweezers for pinching and pulling out hairs from the skin. The epilation device further has a drive unit for driving the at least one epilation barrel and a control unit. The control unit is able to analyze the force with which the user presses the epilation unit to the skin resulting in contact pressure and compares the contact pressure applied to at least one threshold contact pressure. Optionally, the epilation device further has a feedback unit which signals to the user, whether the contact pressure applied is smaller than, equal to, or larger than the at least one threshold contact pressure.

  • Patent number: 10414059
    Abstract: Handle is provided for battery operated razors. In some implementations, the handle includes a simple, efficient mechanism for both securing a battery cover to the handle of a razor and at the same time providing a high reliability electrical contact between the battery and electronics of the razor. The mechanism includes a closing system, including a first conductive component slidably attached within the battery cover and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip portion. The first conductive component is configured to interact with the second conductive component and move axially within the battery cover during engagement of the battery cover with the grip portion.

  • Patent number: 9989596
    Abstract: A circuit for displaying the state of a battery that is almost discharged features a battery, an inductive load, and a controllable switch connected in series. The circuit also includes a display element connected in series with the inductive load and the battery. The controllable switch is opened when a voltage of the battery is lower than a first threshold level and is only closed again when the voltage of the battery is greater than a second threshold level. The circuit may also include a control circuit having a comparator which compares the voltage of the battery with the first threshold level and the second threshold level and triggers the controllable switch accordingly.

  • 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.
