Abstract: An optical sensor arrangement for time-of-flight comprises a first and a second cavity separated by an optical barrier and covered by a cover arrangement. An optical emitter is arranged in the first cavity, a measurement and a reference photodetector are arranged in the second cavity. The cover arrangement comprises a plate and layers of material arranged on an inner main surface thereof. The layers comprise an opaque coating with a first and second aperture above the first cavity, and with a third and fourth aperture above the second cavity. The measurement photodetector is configured to detect light entering the second cavity through the fourth aperture. The second and the third aperture establish a reference path for light from the emitter to the reference photodetector.

Abstract: An integrated current sensor system has a printed circuit board with a magnetic field sensor with a sensor interface. The printed circuit board has a first side on which, isolated from the printed circuit board, a first current conductor is arranged with a longitudinal edge of a portion of the first current conductor being proximate to a sensitive area of sensor. The circuit board has a second side on which a second current conductor is, isolated from the printed circuit board, arranged, wherein a longitudinal edge of a portion of the second current conductor is arranged proximate to the sensitive area. The first and the second current conductor are electrically connected with at least one conductive via.

Abstract: A particulate matter sensor module includes a light source and a light detector mounted on a substrate. A housing is attached to the substrate and includes first and second sections attached to one another in a stack over the substrate such that the first section is disposed between the substrate and the second section. The first and second sections, in combination, define a light reflection chamber, a fluid flow conduit, a particle-light interaction chamber, and a light trap chamber. The first section has a first aperture through which light emitted by the light source can pass to a reflective surface within the light reflection chamber. The reflective surface is configured to reflect the light toward the particle-light interaction chamber where the light can interact with particles in a fluid flowing in the fluid flow conduit. The first section has a second aperture through which light scattered in the particle-light interaction chamber as a result of interaction with one or more of the particles can pass for sensing by the detector. The fluid flow conduit includes a fluid inlet portion having an end coupled directly to the particle-light interaction chamber.

Abstract: The optical sensor package comprises an optical sensor device with a sensor element arranged inside a housing comprising a cap. A diffuser is arranged in an aperture of the cap opposite the sensor element and prolongs the cap in the aperture or closes the aperture. The method comprises forming a cap with an aperture, arranging a diffusing material in the aperture, thus forming a diffuser, and after forming the diffuser, arranging an optical sensor device with a sensor element inside a housing that includes the cap, such that the sensor element is opposite the diffuser.

Abstract: A method of producing an optical sensor at wafer-level, comprising the steps of providing a wafer having a main top surface and a main back surface and arrange at or near the top surface of the wafer at least one first integrated circuit having at least one light sensitive component. Furthermore, providing in the wafer at least one through-substrate via for electrically contacting the top surface and back surface and forming a first mold structure by wafer-level molding a first mold material over the top surface of the wafer, such that the first mold structure at least partly encloses the first integrated circuit. Finally, forming a second mold structure by wafer-level molding a second mold material over the first mold structure, such that the second mold structure at least partly encloses the first mold structure.
