Abstract: An apparatus for controlling an airbag module in a vehicle cabin is provided that includes a control apparatus for triggering the airbag module, a plenoptic camera configured as a camera module that generates image data having depth information within a prespecifiable region in the vehicle cabin with the prespecifiable region comprising at least a first and a second partial region of a trigger region of the airbag module, and an evaluation device which determines on the basis of the image data whether an object, in particular a vehicle occupant, is located in the first or the second partial region and the control apparatus controls the airbag module in dependence on the position of the object.

Abstract: A device and method for measuring a power density distribution of a radiation source is provided. The device includes a radiation source designed to emit a light beam in a radiation direction; a substrate disposed downstream of the radiation source in the radiation direction and having an extent in an x-direction and a y-direction, the substrate having a first region and at least one further second region, and the first region comprises a diffractive structure designed to separate the light beam impinging on the substrate into a zeroth order of diffraction and at least one first order of diffraction; and a detector unit disposed downstream of the substrate in the radiation direction and designed to measure the intensity of the first order of diffraction transmitted through the substrate and to derive a power density distribution therefrom.

Abstract: Improved packages for light emitters may be fabricated at the wafer level. The package can be a single device or an array of die. The package includes a thermal via that extends through the thickness of the package substrate. The thermal via may be made of a material possessing a high thermal conductivity. The thermal via may be wider at the package exterior than at the interior to provide heat spreading between the device and its heat sink. The taper angle of the thermal via may be around 45 degrees to match the natural spread of heat in a solid. The thermal via may extend above the package interior, so its height is sufficient to position an emitter placed thereon at one foci of a parabola, where the vertex of the parabola is at the surface of the package substrate from which the thermal via extends.

Abstract: A monolithic polarization controlled angle diffuser includes a system having a first surface and a second surface, a controlled angle diffuser pattern for providing an angular distribution at an illumination plane, the controlled angle diffuser pattern being on one of the first and second surfaces of the substrate, and a polarizing pattern on one of the first and second surfaces of the substrate. The controlled angle diffuser pattern includes at least two controlled angle diffuser elements. Each controlled angle diffuser element outputs different angular distributions. The polarizing pattern includes at least two polarizing elements. Each polarizing element corresponds to a respective controlled angle diffuser element. The at least two polarizing elements output polarizations are rotated with respect to one another.
