Abstract: The present disclosure relates to various embodiments of an optical package for a LIDAR sensor system having a substrate including an array of a plurality of capacitors formed in the substrate, a plurality of switches formed in the substrate, where each switch is connected between at least one laser diode and at least one capacitor of the plurality of capacitors; and at least one laser diode being mounted in close proximity to the plurality of capacitors on the substrate in order to provide small parasitic inductances and capacitances. A processor is configured to control the plurality of switches to control a first current flow to charge the plurality of capacitors, wherein the processor is configured to control the plurality of switches to control a second current flow to drive the at least one laser diode with current discharged from at least one capacitor of the plurality of capacitors.

Abstract: An apparatus for sterilizing a liquid comprises a container having an inlet, an outlet and an interior with an outer wall which defines a first section and a second section, the first section being configured to receive the liquid. A rotatable arrangement set up in the interior with a surface is furthermore provided, the rotatable arrangement being configured in such a way that during a rotation the surface moves from the first section into the second section and from there back into the first section. The apparatus furthermore comprises at least one radiation source which is adapted to emit radiation in the ultraviolet wavelength range.

Abstract: A device for sterilising a fluid flowing therethrough by comprises a container having an inlet for receiving the fluid and an outlet for discharging the fluid, a variable or adjustable irradiation zone for irradiating the fluid with UV radiation. The irradiation zone including a gap which extends between two oppositely arranged walls. The distance between the walls, and thus the gap size of the gap, can be changed by at least one wall being movable. For example, the wall is a wall of a displaceable body that is located inside the container or projecting into the container. By adjusting the distance between the walls in the region of the gap, and thus the layer thickness of the fluid flowing through the gap, the efficiency of the operation of the device is optimised with different scattering and absorption properties of the fluid.

Abstract: An apparatus for sterilizing a liquid comprises a container (10) having an inlet (12), an outlet (14) and an interior (16) with an outer wall (18), and at least one light source (32) which is adapted to emit radiation in the ultraviolet wavelength range, in particular UV-C radiation, through the outer wall (18) into the interior (16), the outer wall (18) of the interior (16) for this purpose being configured to be at least partially transparent. The inlet (12) comprises at least one opening (28), which is positioned and aligned in relation to the outer wall (18) of the interior (16) and the at least one light source (32) in order, when a pressure is exerted on the liquid to be admitted through the at least one opening (28) and to be sterilized, to form a liquid jet (30) directed onto the outer wall (18) in a region of the at least one light source (32) and/or above the latter, and/or to form a liquid film (31) there. The liquid jet (30) impinging on the outer wall (18) may, for example, flow down thereon as a thin liquid film (31) in front of the at least one light source (32) and thereby lead to effective sterilization even with a low penetration depth of the UV radiation.

Abstract: An optical arrangement for disinfection in apparatuses operating with air or a liquid comprises at least one radiation source or at least one group of radiation sources, which emits or jointly emit radiation in the ultraviolet wavelength range, at least one beam collecting optical unit, which collects the radiation emitted by the radiation source or the group of radiation sources, a number of beam delivering optical units, each configured to receive the radiation collected by the at least one beam collecting optical unit, and also a number of effect zones spatially separated from one another, into which the radiation delivered via the beam delivering optical units is emitted in order to bring about a disinfecting effect.

Abstract: The present disclosure relates to various embodiments of an optical component for a LIDAR Sensor System. The optical component includes a first photo diode implementing a LIDAR sensor pixel in a first semiconductor structure and configured to absorb received light in a first wavelength region, a second photo diode implementing a camera sensor pixel in a second semiconductor structure over the first semiconductor structure and configured to absorb received light in a second wavelength region, and an interconnect layer (e.g. arranged between the first semiconductor structure and the second semiconductor structure) including an electrically conductive structure configured to electrically contact the second photo diode. The received light of the second wavelength region has a shorter wavelength than the received light of the first wavelength region.
