  • Medical suction control with isolation characteristics
    Patent number: 7959604
    Abstract: A suction regulator for controlling a level of negative pressure in a system in which compensatory clean airflow is used to isolate a control device for regulating suction delivered to a patient is disclosed. The regulator comprises an inlet; an outlet; a controller for controlling the suction delivered to the inlet; and a barrier for isolating the controller from the inlet.
    Type: Grant

  • Method and circuit arrangement for determining the average current consumption of a battery-operated apparatus
    Patent number: 7183747
    Abstract: The average current consumption of an electronic apparatus is determined in that an energy store C is repeatedly charged and discharged across the apparatus 1 between a set upper threshold value Uso and a set lower threshold value Usu during a typical operating sequence of the apparatus 1 and within a set measuring time T. The number N of charging processes occurring within the measuring time T is counted and the average current consumption is calculated therefrom while taking into account set values.
