Abstract: A sensor device comprises an array of photodetectors. A multiplexer circuit is connected to the array of photodetectors and provides dedicated output paths for each photodetector in the array, respectively. Furthermore, the sensor device comprises at least one control terminal. An array of time-to-digital converters is connected to output terminals of the multiplexer circuit. Depending on a control signal to be applied at the at least one control terminal, the multiplexer circuit is arranged to electrically connect only the output paths of a subarray of photodetectors to the output terminals of the multiplexer circuit.

Abstract: A housing wall includes at least one air grid having at least a first layer with a first mesh structure and a second layer with a second mesh structure. The first mesh structure is coextensively arranged with the second mesh structure. The first layer and the second layer are electrically conductively coupled. The first mesh structure includes a first plurality of through-holes. The second mesh structure includes a second plurality of through-holes. The through-holes of the first plurality of through-holes are misaligned compared to through-holes of the second plurality of through-holes such that a nonuniform total through-hole configuration of the air grid is provided.

Abstract: The invention relates to a semiconductor component with a chip, especially with a high-frequency switching circuit. The semiconductor component further comprises a metal body on the chip and a supplementary circuit board. The supplementary circuit board is provided on an underside facing away from the metal body for connection with a printed-circuit board by means of reflow soldering.

Abstract: The invention relates to a gas discharge laser including a discharge tube (1), in which a gas is present and which has at least one aperture (19) through which a laser beam emerges or at which a laser beam is reflected. For withdrawing a partial amount of the gas contained in the discharge tube (1), at least one gas withdrawal point (9) is present, from which the withdrawn gas is supplied to a sintered filter (11) for being cleaned. The cleaned gas may be led in via at least one gas inlet point (27) in the zone of the aperture (19). The invention further relates to a method of operating a gas discharge laser, and the use of a sintered filter for cleaning gas withdrawn from a discharge tube (1) of a gas discharge laser.
