  • Patent number: 11771536
    Abstract: The invention relates to an additive method for producing a dental working model for an articulator, comprising the steps: additively producing a base plate for attachment to the articulator, and additively producing a dental model, wherein the base plate and the dental model are configured to be fixed to one another in a positionally secure manner. Another object of the invention is an additively produced dental working model for an articulator, comprising an additively produced base plate configured for attachment to the articulator, and an additively produced dental model, wherein the base plate and the dental model are configured to be fixed to one another in a positionally secure manner.

  • Patent number: 11444616
    Abstract: A semiconductor switch device includes a switchable power semiconductor and a control circuit. The semiconductor switch device has a current sink and a current amplifier designed to amplify during a switching process a partial current of the total current flowing across the control capacitor that is not discharged by the current sink up to an adjustable maximum current and to apply the amplified partial current to the control electrode of the power semiconductor so as to counteract the change in the voltage across the collector-emitter path or the drain-source path of the power semiconductor during the switching process. An additional circuit provides an adapted switch-on transition by smoothing the collector voltage and/or the drain voltage of the switchable power semiconductor when switching over the collector-emitter path or the drain-source path of the power semiconductor from a blocked state into a conductive state.
