Abstract: An antenna has an antenna body having a plurality of first antenna elements, which are disposed along a first straight line. A hollow conductor, which extends between the first antenna elements, is disposed in the antenna body. The first antenna elements are developed as openings running between the hollow conductor and a surface of the antenna body. The antenna is designed to radiate a signal in a spatial direction that is a function of a frequency of the signal. The antenna body has an electrically insulating material that is coated with a conductive material.

Abstract: An antenna has an antenna body having a plurality of first antenna elements situated along a first straight line. The antenna body includes a first conductive grounded surface and a second conductive grounded surface, the first and second grounded surfaces being situated essentially parallel to one another. A dielectric is situated between the first and second grounded surfaces. A signal conductor is also situated between the first and second grounded surfaces. The first antenna elements are designed as apertures situated above the signal conductor in the first grounded surface. Furthermore, the antenna is designed to emit a signal in a direction in space, depending on a frequency of the signal. At least two of the first antenna elements differ from one another in such a way that their power emissions are different.

Abstract: In order to enhance a safety system, in particular an accident avoidance system for a means of transportation, in particular a motor vehicle, having at least one steering system and at least one brake system in such a way that an avoidance maneuver initiated by the operator of the means of transportation when approaching an obstacle is supported with respect to both the device and the method, thus preventing an accident through collision, the evaluation unit determines at least one driving variation, in particular at least one avoidance trajectory and/or at least one automatic emergency braking action from the data and information and when or after the operator of the means of transportation initiates a driving maneuver, in particular an avoidance maneuver or an emergency braking maneuver, the safety system, in particular the evaluation unit specifies, supports and/or suggests this driving maneuver in an optimized form, in particular in the form of an optimal avoidance trajectory or in the form of an automati

Abstract: In an antenna, e.g., for radar signals, a substrate carries two pairs of diametrically opposed antenna elements, first diametrically opposed antenna elements being oriented in a direction that considerably deviates from the direction of second diametrically opposed antenna elements, e.g., by 90°, and the first and second diametrically opposed antenna elements each lying symmetrically with respect to the point of intersection of their orientation directions.

Abstract: A method and a radar sensor for transmitting frequency-modulated transmitted signals and receiving partial waves reflected by objects in the sensor detection range. A frequency shift of the received signal relative to the transmitted signal is determined for each object reflecting in each frequency ramp, it being possible to determine the relative speeds and the distances of the detected objects from the combination of frequency shifts of a plurality of ramps. The objects detected in preceding measurement cycles are stored in a memory, their relative speed and their distance being computed in advance for a future measurement cycle. The expected frequency shifts are determined and the frequency shifts of a plurality of ramps are combined in order to determine the relative speeds and the distances for objects that have not yet been stored in the memory.

Abstract: An arrangement for providing indirect lighting to at least one coverable recess in a vehicle is provided. The at least one recess is arranged on the side of a control panel of a motor vehicle. In the recess electrical components are arranged and the recess is closed with a detachable cover.

Abstract: An optical communication system is described wherein a center (1) and distant terminals (3, 4) are connected to a fiber-optic network (2). Each of the terminals (3, 4) has a light source (5, 7) and a modulator (6, 8) connected thereto for transmitting optical signals to the center (1). Each of the modulators (6, 8) controls the respective light source (5, 7) in such a way that the light source (5, 7) emits light only within successive first time intervals T.sub.1L, T.sub.2L which are separated by second time intervals T.sub.1D, T.sub.2D and that the first time intervals T.sub.1L, T.sub.2L are shorter than the second time intervals T.sub.1D, T.sub.2D.
