  • Patent number: 11076486
    Abstract: The invention relates to an electronic unit (100, 100?) comprising at least one printed circuit board (10, 10?, 20) which is populated with a plurality of electric and/or electronic components (50, 50.1, 50.2) on one side or on both sides and which is incorporated into at least one protective housing (90) made of a solidified potting compound (80?). In the process, the electronic unit overall forms a volume body (200) in which the solidified potting compound takes up a filling volume (70). In order to minimize the filling volume, the electronic unit additionally comprises a separate insert molding part (60) which is arranged at least adjacently to a populated side of the at least one printed circuit board and which takes up a spatially closed displacement volume in the volume body with respect to a flowable potting compound for forming the protective housing in a solidified state (80?).

  • Publication number: 20200304336
    Abstract: A device and method for filtering safety-relevant interventions, having a control unit as well as a first communications unit, which is able to exchange data with at least one bus system of a vehicle, and having a second communications unit, which is able to exchange data with an external processing unit. A third communications unit is provided, which differs from the first communications unit and the second communications unit, and the control unit filters the data transfer between the first communications unit and the second communications unit as a function of a parameter received by the third communications unit.

  • Publication number: 20130076383
    Abstract: A method for testing an integrated circuit and an integrated circuit. The integrated circuit has an internal testing structure which may be accessed via an internal test access port and a control bus which is conducted to the outside via control ports, it being possible to switch over between a running mode and a test mode so that, in the test mode, the test access port is accessed via the control ports and the control bus, thus testing the integrated circuit.
