Abstract: A sensor cleaning apparatus, for cleaning a sensor field of a sensor, in particular a LiDAR sensor, of a vehicle, includes at least one wiper drive housing, which houses at least a majority of at least one wiper drive unit. At least one wiper is arranged at least partially outside of the wiper drive housing and is configured to clean the sensor field by way of a wiping motion. At least one wiper receiving element is provided for transferring a drive movement from the wiper drive unit to the wiper. The sensor cleaning apparatus further includes a sealing unit configured for an at least water-tight seal of the wiper drive housing and includes at least one movable passage opening for the wiper receiving element and/or for the wiper.

Abstract: A wiper device (10a-10f) for wiping a sensor system (30a-30f), in particular a lidar system, with at least one wiper unit (12a-12f), which comprises at least one wiper lip (16a-16f) for wiping a surface (38a-38f) of the sensor system (30a-30f) and with at least one pressing unit (14a-14f). It is proposed that the pressing unit (14a-14f) comprises at least one spring element (24a; 52b; 54c, 56c; 58d; 60e; 62f, 64f) for pressing the wiper unit (12a-12f) against the surface (38a-38f).

Abstract: A wiper device having a wiper arm (20a; 20b; 20c), having at least one wiper blade (18a, 18a?, 18a?) which is coupled to the wiper arm (20a; 20b; 20c), which includes at least one wiper lip (22a, 22a?, 22a?) for wiping a surface (16a; 16b; 16c) of a protective element (14a; 14b; 14c) of a sensor device (12a), in particular of a Lidar device, and having a wiper arm guide unit (24a) which is provided for moving the wiper arm (20a; 20b; 20c) in an at least substantially translatory manner along a guide path (50a). It is proposed that the wiper device has a rotary joint (26a) by means of which the wiper blade (18a, 18a?, 18a?) is pivotably mounted on the wiper arm (20a; 20b; 20c).

Abstract: The invention relates to a lidar device (10a-10l) having a cleaning unit (12a-12l) which has at least one wiper unit (14a-14l) having at least one wiper blade (16a-16l) for mechanically cleaning a cover element (18a-18l) of a lidar unit (20a-20l), and having at least one pressing element (22a-22l) which in a mounted state provides a pressing force for the wiper blade (16a-16l).

Abstract: A reactor (6) for pyrolysing waste, in particular rubber tires, said reactor comprising a pyrolysis space (68), an inlet port (63) and an outlet port (64) enabling a flow across the pyrolysis space (68) of a heating medium for transferring heat required for the pyrolysis, and a lower discharge port (62) for discharging solid residues of the pyrolysis. The invention is, characterized in that—it comprises a baffle means (65) made of a plate material and enabling a gravitational slipping of the solid residues towards the discharge port (62), which baffle means (65) has openings (66) allowing the flow of the heating medium and is arranged to divide the inner space of the reactor (6) to form an upper pyrolysis space (68) and a lower space and—one of the inlet and outlet ports (63, 64) is in connection with the pyrolysis space (68) and the other one with the lower space. The invention is also an apparatus comprising the above reactor (6).
