Abstract: For ultrasonic measurement of pipe seam peaking, optionally with simultaneous ultrasonic wall thickness measurement using ultrasonic probes mounted on sensor holders on a sensor mount, it is proposed to use a sensor mount with sensor holders mounted on movable skids, which are pressed outward by spring elements and bear against the internal pipe surface, and skids having a large skid breadth greater than the seam peak breadth measured in the pipe's circumferential direction in the region of a measured seam peak, and sensor holders equipped with sensors only in a measuring region situated half way between two skid contact surfaces, wherein the measuring region breadth is less or equal to half of the skid breadth such that the stand off deviation of the sensors resulting in the seam peak region remains below a threshold value.

Abstract: A sensor system is described for detecting wetting of a window includes a photodetector having multiple light-sensitive elements and a light source for emitting light to a detection region of the window in such a way that a portion of the light is reflected at the window, and another portion of the light passes through the window. The light source and the light-sensitive element are situated in such a way that a portion of the light from the light source which passes through the window is reflected at the wetting and strikes a portion of the light-sensitive elements. The light source includes a lighting element which is set up to irradiate into a transparent body. The transparent body has a surface which has defined unevennesses for the diffuse radiation of the irradiated light.

Abstract: A camera system, e.g., for a vehicle, includes: at least one objective for detecting a detection region, one image sensor for outputting image signals, and one auxiliary optics situated in the detection region, the auxiliary optics together with the objective forming an optical imaging system for imaging a two-dimensional detection region on the image sensor. The auxiliary optics is formed by one auxiliary lens having an entrance surface and an exit surface, and the two-dimensional detection region does not extend vertically with respect to the optical axis of the auxiliary lens and is imaged sharply on the image sensor by the optical imaging system. The entrance and exit surfaces do not have a spherical curvature.

Abstract: A camera system for use in a vehicle for simultaneously recognizing rain on its windshield and for monitoring the surroundings, includes: a camera having a camera lens and an image sensor, a mirror system having at least one first mirror and at least one second mirror which are situated in such a way that they define a beam path from a monitored area of the windshield to the first mirror, from there to the second mirror, and from there through the camera lens to a first subarea of the image sensor, the distance along the beam path between the at least one second mirror and the camera lens being smaller than the distance along the beam path between the at least one second mirror and the monitored area.

Abstract: Disclosed is a segment (15) of a sensor-supporting element for a scraper-type device, which comprises at least two pairs of runners (16a, 16b) that are arranged essentially parallel behind each other. A support plate (20) receiving sensors (21) is disposed between at least one pair of runners (16). The segment (15) can be combined with other such segments (15) so as to form a sensor-supporting element.

Abstract: In a biosensor system for detecting trace compounds resulting from a fire or from plants damaged by destructive insects, a live chemoreceptor is provided for sensing the trace compounds, and a semiconductor component is connected to the chemoreceptor for providing sensor signals when the chemoreceptor senses the presence of trace compounds.
