Abstract:
The invention relates to a camera system (1) for vehicle applications, designed to be mounted behind a windscreen (8) of a vehicle and comprising the following: at least one optical system (2) for imaging electromagnetic radiation; at least one image sensor (3) for detecting the imaged electromagnetic radiation and converting it into electrical signals; and an evaluation unit (4) for processing the electric signals. The invention is characterised in that the camera system also comprises the following: a controllable light source (6) for generating electromagnetic radiation for an optical test of the camera system, and an electronic testing system (5) for evaluating the electric signals converted by the image sensor and for controlling the light source. The camera system is also designed such that the electromagnetic radiation generated by the light source is imaged onto at least part of the image sensor by means of the at least one optical system, and the electronic testing system evaluates the electrical signals generated by the image sensor in this way for operational readiness and for definition of functional values of the camera system.
Abstract:
The invention relates to a means of transport having a three-dimensional distance camera and a method for building and operating said three-dimensional distance camera in means of transport, more particularly in motor vehicles. The inventive method, and especially the inventive device, is suitable for utilization in motor vehicles as braking assistant system, damage reducing system, closing velocity sensor system, preferably as collision detection system in the front area, the sides and/or the rear, for accident prevention, pedestrian protection, as stop-and-go or jam assistant system, parking assistant system, for example, parking space measurement, parking assistant system and/or autonomous parking. The invention can also be advantageously used for blind spot monitoring, as lane departure warning system, lane changing assistant system, more particularly with blind spot monitoring and/or lane position detection, lane keeping support, overturning and/or pitching angle detection system. Furthermore, the invention can be advantageously used for night vision, as road condition detection system, door stopper, traffic sign detection system, light sensor, weather sensor, passability sensor and/or for docking support or back-up support.
Abstract:
The measuring electrodes (1) are provided by a flexible, expandable conductive material and pressed into contact with the walls (2) of the borehole or the fissure via pneumatic or hydraulic pressure devices. The electrodes are used selectively for supplying electrical currents or measuring electrical potentials. An Independent claim for a geoelectric measuring device with electrodes of a flexible, expandable conductive material is also included.
Abstract:
The method determines also the distance speed of a flow movement or a marking material in the background, by measuring spatially variable and intermittent electrical potential distribution. The measurements of the electric potentials related to a reference potential electrode, result by multi-electrode arrangements in linear, areal, and/or spatial electrode system. In addition to stationary, electrical potential fields also intermittent electrical potential fields can be determined, by the esp. construction of the recording system. The measurements of potential values with the selection of one or more combinations of electrodes, result for the current supply, in repeatable and/or variable measurement sequence and measurement duration as well as measurement cycle sequences.
