Abstract: An apparatus includes an antenna assembly including an antenna configured to receive a signal and generate, at a plurality of feed points of the antenna, a plurality of corresponding polarized signals having respective polarization directions different from each other, using the received signal; and a switching circuit configured to periodically switch between the plurality of feed points to select a corresponding one of the polarized signals among the plurality of polarized signals at a point of time based on a switching signal.

Abstract: An apparatus includes an antenna assembly including an antenna configured to receive a signal and, based on the received signal, generate a first linearly polarized signal at a first feed point and a second linearly polarized signal at a second feed point; and a switching circuit configured to periodically switch between the first feed point and the second feed point to select a polarized signal between the first and second polarized signals at a point in time based on a switching signal.

Abstract: A system for determining an object position on a site with large machinery, particularly a mine site, a construction site, or an agricultural area, based on radio frequency time-of-flight ranging. The system is configured to determine a current position of a reference point indicative of a position of a machine on the site, to access an arrangement dataset indicative of a positional relationship between the reference point and a mounting location on the machine of at least one anchor of a point-to-point radio ranging unit, and to determine a position of the at least one anchor based on the current position of the reference point and the arrangement dataset, wherein the position of the at least one anchor is provided to a position determining unit configured for determining position information of tags based on ranging data of the point-to-point radio ranging unit.

Abstract: A driving assistance system for reversing a mining haulage vehicle, particularly for reversing a haul truck into a defined target position in a loading or dumping area, wherein the driving assistance system is configured that the target position is determined based on a logged loading tool position of the earthmoving machine, wherein steering instructions are provided to a light indicator when the transmission of the haulage vehicle is shifted to reverse.

Abstract: A multiband patch antenna, a method for receiving radio frequency signals in multiple bands by a multiband patch antenna and a method of producing a patch element are disclosed. The antenna comprises a substrate layer having a first surface and a second surface and a base element on the first surface. A multi-resonance patch element comprising a pattern of outward extending resonance formations is provided on the second surface. At least two proximity feed elements configured for connection to a multiband hybrid coupler circuit and extending within the substrate layer from the first surface to the second surface are also provided. The multi-resonance patch element is configured to leave areas where the proximity feed elements extend to the second surface uncovered by the multi-resonance patch element.

Abstract: A multiband antenna assembly for transmitting or receiving signals in at least two frequency bands is disclosed according to some embodiments. The multiband antenna assembly may include a monopole antenna with a base substrate and a top substrate having defined dimensions and shapes. In some embodiments, the base substrate and the top substrate are arranged with defined distance relative to each other and define a cavity. For example, a first frequency band is basically defined by the present distance. The top substrate may include at least one slot. A second frequency band basically is defined by the design and arrangement of the one slot. The second frequency band may be different from the first frequency band. The cavity may be designed so that the first and the second frequency band comprise preferred monopole sending and/or receiving directions substantially parallel to the extension of the substrates.
