Abstract: Example systems and methods are disclosed for determining vehicle pose data for an autonomous vehicle. The vehicle computer system may receive pose data from multiple pose measurement systems of the autonomous vehicle. Each pose measurement system may include one or more corresponding sensors of the autonomous vehicle. The vehicle computer system may determine a pose data quality for the received pose data for each pose measurement system. The vehicle computer system may set the vehicle pose data to the pose data of the pose measurement system with the highest pose data quality. The vehicle computer system may control the autonomous vehicle based on the vehicle pose data.

Abstract: A method and apparatus are provided for determining the location of a vehicle. According to one aspect the method and apparatus the movements of motor rotors in a vehicle are monitored and used to determine speed, travel distance and/or travel path of a vehicle may be determined. Using various navigation techniques, the distance and travel path may then be used to determine the vehicle's location. Furthermore, movements of the motor rotors may also be used to report the positions of the steering and drive systems for the purpose of informing the vehicle controller as a method of feedback.

Abstract: The present application discloses a dual open-ended waveguide (DOEWG) antenna apparatus. The apparatus may include a plurality of radiating elements configured to radiate electromagnetic energy. Each radiating element may have an associated amplitude and phase. The apparatus may further include a waveguide configured to propagate an electromagnetic signal from a waveguide feed to the radiating elements. The radiating elements are arranged in a plurality of doublets. Each doublet includes at least two radiating elements and is coupled to the waveguide via a respective doublet neck. At least one doublet in the plurality of doublets is coupled to the waveguide via a doublet neck that has a first height proximate a first radiating element in the at least one doublet and a second height proximate a second radiating element in the at least one doublet in which the first height is different from the second height.
