Abstract: A method and system for the optimized determination of machine parameters of an agricultural production machine is disclosed. The agricultural production machine has a driver assistance system and a sensor assembly and performs an agricultural task in a local context. A determination routine the driver assistance system uses the strategy specifications as input parameters of the instruction for use to determine the optimized machine parameters optimized with respect to the strategy specifications as output parameters of the instruction for use, wherein the strategy is parameterized with initial strategy parameters at the beginning of the execution of the agricultural task. The driver assistance system uses strategy parameters as the initial strategy parameters that have already been optimized by at least one agricultural production machine in a similar local context.

Abstract: A bumper antenna assemblage that permits improved reception is described. The bumper antenna assemblage comprises an antenna element in a bumper of a vehicle body, the antenna element being constituted by an electrically conductive surface in the bumper. The electrically conductive surface forms, on a side facing toward the vehicle body, a slot with respect to the body panel. An antenna terminal is provided at at least two different points on the electrically conductive surface.

Abstract: The invention relates to a module (10) for exchanging radio data, particularly mobile radio data, comprising: transmitting/receiving electronics for processing mobile radio signals to be transmitted and/or received; shielding means (12) for electromagnetically shielding the transmitting/receiving electronics, and; a transmitting/receiving antenna (22) for transmitting and/or receiving mobile radio signals. The shielding means (12) have at least one electrically conductive shielding cover (12) that encapsulates the transmitting/receiving electronics. The transmitting/receiving antenna (22) is placed in the vicinity of the at least one shielding cover (12) so that the latter serves, at least in sections, as a ground surface during the transmission and/or reception of mobile radio signals.

Abstract: A slotted antenna can be used for operation in multiple frequency ranges. The slotted antenna has a first electrically conducting disc which is offset from an electrically conducting base area which forms a reference potential, the disc being connected at its outside edge to the base area by at least one first electrically conducting web. The first disc includes a recess. Above the recess, a second electrically conducting disc is situated and is connected at its outside edge to the first disc by at least one second electrically conducting web. An antenna conductor leads to the second disc.

Abstract: Rod-shaped multi-band antennas require at least one parallel resonance circuit for separating the individual frequency bands, which consists of a coil and a discrete capacitor. Multi-band antennas of this type for a maximum of three frequency bands are as a rule only suitable for a frequency range from 3 to 30 MHz. In a multi-band antenna (10) suitable for four frequency bands, a first coil (15) is located between a first and a second straight wire piece (14, 16), and a second coil (17) between the second, straight wire section (16) and a third, straight wire piece (18). The first coil constitutes a parallel resonance circuit or a trap circuit, and the second coil a phase shift coil. The multi-band antenna is particularly suited as a vehicle aerial to which a car radio for the AM and FM ranges as well as a mobile telephone for two different nets is connected. The drawing illustrates a rod-like multi-band antenna in accordance with the invention.

Abstract: An elongated rod 11 of dielectric material, for example fiberglass--plastic or the like, has a central conductor (12) located coaxially therein, the conductor having a length L=3/2 .lambda.; in the central .lambda./2 range, the insulating rod is surrounded by a conductive layer (13, 16, 20, 25), for example of conductive lacquer, a mesh or braid of conductive material, a conductive foil or tube or the like. In the lower .lambda./2 region of L1, the bottom terminal of the central conductor will provide a high resistance output for the higher one of the frequency ranges which, for example, can be a radio telephone, or vehicular communication frequency of between 450-470 MHz. The entire antenna is suitable as an AM-FM/radio-telephone combination antenna. .lambda. is the median operating wave length of the higher one of the frequency ranges for which the antenna is suitable. Preferably, the antenna is covered with a sleeve of insulating material, for example a heat shrinkable plastic (27).
