  • Patent number: 10551484
    Abstract: A radar system includes a plurality of radiating elements configured to radiate electromagnetic energy and a plurality of feed waveguides defining a common plane and configured to guide electromagnetic energy to the plurality of radiating elements. The radar system also includes a plurality of waveguides arranged as a dividing network configured to split the electromagnetic energy from the source among the plurality of feed waveguides, such that each feed waveguide receives a respective portion of the electromagnetic energy. Additionally, the dividing network is configured to adjust a phase of the electromagnetic energy received by each waveguide. The splitting and adjusting of the dividing network may be based on differences in height and/or width between the waveguides of the dividing network and the feed waveguides. At least a portion of the dividing network is located in a plane other than the common plane of the feed waveguides.

  • Patent number: 10509120
    Abstract: A method and apparatus for calibrating a LiDAR system at a first location with a radar system at a second location. A calibration target is placed at a location and orientation with respect to the LiDAR system and the radar system. Coefficients of a plane of the calibration target are determined in a frame of reference of the LiDAR system. Coordinates of the calibration target are determined in a frame of reference of the radar system. A cost function is composed from a planar equation that includes the determined coefficients and the determined coordinates and a relative pose matrix that transforms the frame of reference of the radar system to the frame of reference of the LiDAR system. The cost function is reduced to estimate the relative pose matrix for calibration of the LiDAR system with the radar system.

  • Patent number: 10492176
    Abstract: A method performed in a network node of a cellular network that also includes a wireless device, the wireless device being in a discontinuous reception mode having receiving periods and idle periods. The method involves transmitting a first control signal to the wireless device during a receiving period for the wireless device; determining that a first control signal is likely to have failed to be correctly received by the wireless device; and determining that a second control signal needs to be transmitted to the wireless device, the second control signal corresponding to the first control signal. When the wireless device is in an idle period, the method further involves postponing any transmission of the second control signal until the wireless device is in a receiving period; and transmitting the second control signal to the wireless device when the wireless device is in the receiving period.
