Abstract: A device for data projection, includes a holographic element arranged as a imaging element for a windshield. An imaging device has a first imaging system and a second imaging system configured to illuminate the holographic element. The holographic element has a first volume hologram structured to be angle-selective for light under a first illumination angle and to generate a first two-dimensional virtual image at a first fixed distance from the holographic element corresponding to the first image data, and a second volume hologram structured to be angle-selective for light under a second illumination angle and to generate a second two-dimensional virtual image at a second fixed distance from the holographic element different from the first distance corresponding to the second image data, such that the first and second images are viewable separately and simultaneously by a person.

Abstract: A stacked-plate heat exchanger may include a plurality of stacked plates. The plurality of stacked plates may include a plurality of first stacked plates and a plurality of second stacked plates stacked alternately one on top of another. Pairs of adjacent stacked plates may each delimit one of a first cavity for the passage of a first fluid and a second cavity for the passage of a second fluid in an alternating manner. The heat exchanger may also include a support structure that may support the plurality of stacked plates in an edge region to stabilize the second cavity. The plurality of stacked plates may each include a first opening and at least two second openings arranged around the first opening. The heat exchanger may also include a plurality of webs each arranged between two adjacent second openings. The plurality of webs may form the support structure.
