Abstract: A fuel cell stack bipolar plate, includes two half-plates connected to one another and a flow space formed between the half-plates for distributing a coolant flowing into the flow space through an inlet hole of the bipolar plate, located on a first edge of the bipolar plate, and flows out of the flow space through an outlet hole of the bipolar plate, located on an opposite second edge of the bipolar plate, over the area of the bipolar plate's flow field. The flow field debouches at its ends facing toward the first and second edges of the bipolar plate into a distribution region connected to the respective hole. The distribution region includes a pre-distributing channel, which debouches into the respective hole, extends along a direction of the first and second edges of the bipolar plate and has a plurality of throttle apertures arranged distributed and face toward the flow field.

Abstract: The disclosure relates to diagnostic, surgical, and/or therapeutic devices for being introduced into the human or animal body or for in vitro examination of human or animal blood samples or other body cells, in particular to an endoscope or a disposable endoscope that includes at least one illumination light guide and/or image guide for transmitting electromagnetic radiation, the illumination light guide or image guide having a proximal end face for incoupling or outcoupling of electromagnetic radiation and a distal end face for incoupling or outcoupling of electromagnetic radiation. The proximal and/or distal end faces consist of plastic elements that are transparent at least partially or in sections thereof, the transparent plastic being biocompatible and/or having non-toxic properties to human or animal cell cultures for exposure durations of less than one day. This allows for the production of assemblies for disposable endoscopes, inter alia.

Abstract: A fixture for a lamp and to a lighting element are provided that is usable as a reading light, for example in a vehicle or aircraft. The fixture is adapted to be releasably installed in an opening of an accommodating element and includes a cylindrical mounting element having a lateral wall, a front side, and an opposite rear side. The front side has an opening for receiving the lamp. The lateral wall has a radially outwardly projecting rib and a radially outwardly projecting latching element.

Abstract: An illumination system is provided that includes a laser light source, a light guide, a connector, and an emission element. The laser light source has a numerical aperture. The light guide has a proximal end and a distal end. The connector has a connector housing and connects and/or assigns the laser light source at the proximal end. The emission element is at the distal end. The connector housing has a device that reduce an influence of a range of variation of the numerical aperture so that an emission behaviour of the emission element is independent of a range of variation of the numerical aperture.

Abstract: A lighting device for interior spaces or rooms is provided. The lighting device has a plurality of lighting units that are individually calibrated. Further, the lighting device has a regulating device, which, based on corrected color and/or intensity values, forms a control value with which light sources of the lighting units are actuated in order to achieve a specified color and/or intensity value.

Abstract: A termination for a light guide is provided that, on the one hand, allows connection of the light guide to a light source in a simple and reliable manner and, on the other hand, blocks light components that are not guided in the light guide. For this purpose, a ferrule is provided for terminating a light guide. The ferrule includes a transparent plastic part and an opaque light-blocking plastic part that are connected to each other to define a channel. The transparent plastic part has a light entry end that receives an end of the light guide. The channel has at least a portion that extends within the transparent plastic part and at least a portion that extends within the opaque plastic part. The has a collar surrounding the channel and has an outer diameter that is greater than a maximum outer diameter of the transparent plastic part.

Abstract: A light source is provided that includes at least two semiconductor light-emitting elements that emit light of different color, a light guide, an electronic control unit, and a light sensor. The light emitted by the elements is injected, at least partially, into the light guide and exits laterally from the light guide. The brightness of the elements can be adjusted by the electronic control unit. The light sensor is arranged to receive the light injected by the elements and laterally exiting from the light guide. The electronic control unit accumulates sensor signals from the light sensor over an integration time interval and compares the accumulated signals with a target value or range to determine a difference, changes a brightness of the elements in response to the difference, and changes the integration time interval in response to the difference or to a change in the target value.
