  • Publication number: 20200028229
    Abstract: A microwave connector assembly comprises a waveguide ferrule having a receiving end receiving a dielectric waveguide, a connecting end distal to the receiving end, and a locking member, and a ferrule socket at least partially receiving the waveguide ferrule in a ferrule receptacle. The ferrule socket engages in a locking connection with the locking member. The ferrule socket has a coding member engaging a complementary coding member of the waveguide ferrule only when the waveguide ferrule is positioned relative to the ferrule socket in a single predetermined angular position or in one of two predetermined angular positions that are rotated by 180° with respect to each other.

  • Patent number: 10386855
    Abstract: A method for the decentralized coordination of driving maneuvers of at least two motorized transportation vehicles. A planned trajectory and a desired trajectory are transferred from a first motorized transportation vehicle to a second motorized transportation vehicle. In the second motorized transportation vehicle, a planned trajectory of the second motorized transportation vehicle is compared with the desired trajectory of the first motorized transportation vehicle. The planned trajectory of the second motorized transportation vehicle is adapted in response to satisfaction of adaptation criterion. The planned and desired trajectories of the first motorized transportation vehicle are combined with a strategic trajectory of the first motorized transportation vehicle. The planned trajectory and a desired trajectory of the second motorized transportation vehicle are combined with a strategic trajectory of the second motorized transportation vehicle.
