Abstract: Optical blockage of a vehicle camera is determined using an image of a static scene from an environment of the vehicle is recorded with the camera. Recording conditions existing while the image is being recorded are determined. The recorded image is compared with a reference image, which is retrieved from a vehicle-external server, and is based on recordings that have been recorded by a plurality of vehicles of the same static scene in the same or similar recording conditions. Deviations in image features between the recorded image and the reference image are evaluated as being an indication that the camera is optically blocked if they exceed a pre-determined tolerance.

Abstract: A peristaltic pump includes a casing having a bottom, cover and wall forming a pump chamber, a tube connecting a casing inlet to a casing outlet arranged within the pump chamber, and a displacement element having at least two displacement members. The tube is arranged between the casing wall and the displacement element in such a way that due to rotation of the rotor the displacement members roll on the tube so the tube is squashed together so that a medium to be conveyed which is in the tube is displaced in the direction of the casing outlet. The displacement element has a first part fixed to the rotor and a second part which can be reciprocated between an operative position and a change position.

Abstract: A conveyor system (10) for transporting a transportable material (M) by means of a fluid for transporting the transportable material (M) between a first conveying line portion (11) and a second conveying line portion (12), said conveying line portions (11, 12) comprising a plurality of pipes forming a continuous conveying line (13), said system (10) comprising: a conveyor device (1) in fluid connection to one of said first or said conveying line portions (11, 12) operative to provide negative air pressure or vacuum through said conveying line (13); a material feeder device (2); wherein the conveyor device (1) comprises at least one material level sensor (1a, 1b), wherein the at least one material level sensor (1a, 1b) is used to monitor one or more material level(s) inside the conveyor device (1) and via one or more material level sensor lines (3) giving at least one material level signal (1aa, 1bb) to a controller (4) and from the controller (4) via a control signal line (5) transmit a control signal (5a)

Abstract: Described is a peristaltic pump comprising a casing which has a casing bottom, a casing cover and a casing wall extending from the casing bottom to the casing cover, which form a pump chamber, a tube which connects a casing inlet to a casing outlet and is arranged within the pump chamber, and a displacement element which has at least two displacement members and is fixed to a rotor which is rotatable about a rotor axis so that in the rotary movement of the rotor each displacement member performs a movement in an operative plane, wherein the tube is arranged between the casing wall and the displacement element in such a way that due to rotation of the rotor the displacement members roll on the tube so the tube is squashed together so that a medium to be conveyed which is in the tube is displaced in the direction of the casing outlet.
