Abstract: A device has a housing (1) with a frame element (8) which is arranged within the housing (1). The frame element (8) accommodates at least one component and has at least one bending arm (12). The bending arm (12) is designed such that a contact region (36) of the bending arm (12) bears with prestress against a contact region (38) of a wall (34) of the housing (1) in a mounted state within the housing (1). The bending arm (12) is cohesively connected to the housing (1) by means of transmission laser welding by supplying a laser beam (46) of prespecified wavelength to the device in such a way that the laser beam is transmitted through the housing (1) to the contact region (36) of the bending arm (12). At least one region of the housing (1), through which region the laser beam is transmitted, is produced from a material which is transparent to the prespecified wavelength of the laser beam (46).

Abstract: To improve coolant sealing or reduce the risks in the event of leakage for an electronic unit, e.g. an engine control unit, containing electric and/or electronic components which are disposed on an upper side of a thermally conductive electronic base plate and thermally coupled to the base plate, the base plate in turn being thermally coupled to a coolant passage, there is provided a particular configuration and arrangement of the components delimiting a coolant passage. Advantageously, the underside of the base plate can come into direct contact with a coolant (“direct cooling”). By making a ridge running in an annularly closed manner and being formed in one-piece with the base plate, coolant escaping from the coolant passage is prevented from passing directly to the underside of the base plate. Accordingly, the coolant passage may be sealed by a “double sealing arrangement” on the underside of the base plate.

Abstract: The invention relates to a rotary/push-button controller having a controller ring (18) which can be rotated about a rotation axis (7) and is arranged such that it can rotate on a holding cylinder (6) which is arranged coaxially within the control ring (18).

Abstract: A current source includes a first switching element configured to adjust an output current according to a control signal received at a control input. The current source also includes a reference resistance, which is electrically coupled to the first switching element such that the output current flows through the reference resistance. The latter includes first and second individual reference resistors, connected in series, and a diode connected in parallel to the first reference resistor.

A controller receives a predetermined reference potential and an actuating signal that constitutes the control signal of the first switching element.

Abstract: The invention relates to an indicator apparatus (1) having a ring pointer (2), which is mounted such that it can move in the circumferential direction (5), and having a drive unit (3), which drives the ring pointer (2) in the circumferential direction (5), wherein the ring pointer (2) interacts with a stop (10) in a manner limited in terms of its circumferential movement. Particularly in the case of synchronization, radial disengagement often occurs in conventional ring pointer arrangements, and the aim of the invention is to prevent this. In order to solve the problem, the invention proposes arranging the stop (10) directly next to the drive unit (3). The critical advantage of this is that the tangential force on the ring pointer (2) from the drive unit generates an only small disengagement moment on the ring pointer (2).
