Abstract: A printed circuit board composite and a method for producing same. In the method for producing the printed circuit board composite, a first printed circuit board, in particular a sensor carrier printed circuit board, is connected in a form-fitting manner to a second printed circuit board, in particular a supporting printed circuit board. There is also described a printed circuit board composite.

Abstract: The disclosure relates to a control device in a motor vehicle. The control device includes a housing cover with a peripheral edge region, and a planar, electrical connecting apparatus with integrated conductor tracks. The housing cover, in the edge region, is cohesively connected at least to the connecting apparatus and forms a cavity with the connecting apparatus. The control device also includes at least one electronic component within the cavity. The connecting apparatus electrically connects the at least one electronic component to electronic components outside the cavity. The peripheral edge region is encapsulated by injection molding in a media-tight manner by a polymer at least in the region of the connecting seam between the housing cover and the connecting apparatus.

Abstract: The disclosure relates to a method for contacting a contact surface on a flexible circuit board with a metal contact outside the flexible circuit board, with the aid of a press-fit pin. An attachment piece having a sleeve for receiving the press-fit pin is a mechanically and electrically coupled to the flexible circuit board.

Abstract: An electric motor inverter includes at least one DC-link capacitor that has contacting layers. The electric motor inverter also includes circuit breakers which are mounted on at least one substrate, and capacitor connecting plates which are attached with first sections to the contacting layers. Second sections of the capacitor connecting plates which are arranged opposite the first sections are attached to the at least one substrate.

Abstract: The disclosure relates to a mechatronic assembly. The assembly includes a supporting circuit board with at least one populated flat side. A multiplicity of electronic components are arranged on the at least one populated flat side. In addition, at least one mechanical insert part for the mechanical fixing of at least one electronic component is also arranged on the at least one populated flat side. An encapsulation of one-piece design is provided which, in form-fitting and cohesive fashion, surrounds all of the components arranged on the at least one populated flat side of the supporting circuit board. The disclosure also relates to a method for producing the mechatronic assembly.

Abstract: A method and device for operating an electric bicycle that has an electric motor and a transmission with at least two gears is provided. The method includes ascertaining a current pedal frequency that is generated by a user of the electric bicycle and checking whether the ascertained current pedal frequency lies within a specified pedal frequency interval. The method also includes ascertaining a current travel speed of the electric bicycle, ascertaining at least two transmission gears within the specified pedal frequency interval depending on the ascertained travel speed, and ascertaining a respective output of the electric motor for each of the ascertained at least two gears. The method also includes ascertaining the lowest ascertained output of the electric motor by comparing the two ascertained outputs of the electric motor, and ascertaining the transmission gear for which the lowest output was ascertained.

Abstract: An injector for injecting fluid with a valve assembly including a valve body and a valve needle, the needle including an armature retainer and being operable to prevent and to enable injection of fluid, and with an electromagnetic actuator assembly, operable to exert a force for influencing a position of the valve needle, including a pole piece and an armature. The pole piece is positionally fixed with the valve body. The armature is operable to be axially displaced relative to the pole piece and to take along the armature retainer when being displaced towards the pole piece. A fluid channel is defined by the armature retainer constriction surface and the pole piece constriction surface. A hydraulic diameter of the fluid channel is at least twice at large when the valve needle is in a closing position compared to the hydraulic diameter at a maximum displacement away from the closing position.
