  • Patent number: 10203412
    Abstract: A method for determining a position of a machine is disclosed. The method may include determining, using a Lidar unit on the machine, input data associated with distances between the Lidar unit and respective light-reflective points in the worksite. The method may also include comparing the input data with comparison data. The comparison data may have reference data sets indicative of distances between reference positions and the respective light-reflective points in the worksite. The reference positions may have a fixed location in the worksite. The method may further include determining the position of the machine as the reference position corresponding to a reference data set that correlates with the input data set.

  • Patent number: 9020358
    Abstract: An optical transmission network comprises a multi-wavelength source (7) shared between multiple sets of client side equipment for manipulating electrical signals. A first wavelength selective routing element (5) is connected to the multi-wavelength source (7). Each set of client-side equipment (1) comprises an optical modulator (3) connected to the first wavelength selective routing element (5) and an optical receiver (2). A second wavelength selective routing element (6) is connected to the optical receiver (2) and is operative to direct incoming signals from one or more remote locations to the optical receiver (2). The network provides a WDM architecture solution for networks whereby the cost of implementing and running client side equipment (1) is reduced by not having the WDM source (7) within the client side equipment (1).
