    Abstract: The present disclosure relates to optical transmitter modules, lidar systems, and methods of their manufacture. An example optical transmitter module includes a transparent substrate and a plurality of wires disposed along the transparent substrate. The optical transmitter module includes driver circuitry electrically-coupled to at least a portion of the plurality of wires and one or more light-emitter devices electrically-coupled to at least a portion of the plurality of wires. The light-emitter device(s) are configured to emit light pulses. The optical transmitter module also includes a fast axis collimation lens disposed along the transparent substrate. The fast axis collimation lens is configured to collimate the light pulses so as to provide collimated light. The optical transmitter module also includes one or more waveguide structures disposed along the transparent substrate within an optical region. The optical transmitter module also includes a lid configured to provide a sealed interior volume.

    Abstract: Systems, methods, and non-transitory computer-readable media can determine contextual information describing at least one physical structure corresponding to a location based at least in part on data captured by one or more sensors of a vehicle. A set of candidate interaction points for the at least one physical structure can be determined based at least in part on the determined contextual information describing the at least one physical structure corresponding to the location. The set of candidate interaction points can be filtered to identify one or more interaction points. An interaction point can be selected from the one or more interaction points to use for stopping the vehicle.

    Abstract: Systems for inspecting a warehouse are disclosed. A system includes a laser scanner attachable to an industrial truck and adapted to scan in a plane substantially perpendicular to the industrial truck's main direction of travel to scan an environment of a warehouse on at least one side of the industrial truck and to generate scan data. The system includes a computing unit adapted to receive the scan data and data on the absolute position and/or relative position change of the industrial truck, or data from which one or more of these variables can be derived. The computing unit is further adapted to construct three-dimensional data of the environment on the basis of the scan data and data on the absolute position and/or relative position change of the industrial truck.
