  • Publication number: 20250118634
    Abstract: An intelligent power module includes a plurality of controllable semiconductor devices that each include a control electrode, a gate driver configured to generate one or more control signals for one or more of the plurality of controllable semiconductor devices, and one or more bridging devices that each include a housing, a plurality of contact pads arranged on an outside of the housing, and one or more electrical connections arranged inside the housing. Each of the one or more electrical connections electrically couples two of the plurality of contact pads to each other. At least one of the bridging devices is electrically coupled between the control electrodes of one or more of the plurality of controllable semiconductor devices and the gate driver, respectively, and is configured to route one or more control signals from the gate driver to the control electrodes of the one or more controllable semiconductor devices.

  • Patent number: 11913201
    Abstract: A command device for a water supply plumbing fixture that extends along a main axis and has a base group fluidically connectable to at least one inlet line and to supply lines, and an activation and regulation group engaged with the base group is provided. The activation and regulation group has a plurality of activation members configurable in an active configuration and a passive configuration in which the activation members respectively allow or prevent passage of water to a respective supply line, and a regulation member having an annular adjustment crown angularly rotatable, the activation members being housed at least in part within the adjustment crown, and a valve element, housed at least in part inside the adjustment crown, engaged with the base group and with the adjustment crown, so that each angular position of the adjustment crown corresponds to a respective configuration of the valve element.
