Abstract: A tool for applying a protective film to a lens of a light detection and ranging (LIDAR) sensor is disclosed. The tool includes at least one cover, a film spindle, a film roller, and a pivot bar. The at least one cover has an elongated shape with a first end and a second end opposite of the first end. The film spindle is mounted to the at least one cover adjacent to the second end thereof. The film spindle is configured to hold a roll of the protective film. The film roller is mounted to the at least one cover adjacent to the first end thereof. The film roller is configured to apply the protective film onto the lens. The pivot bar has a first end configured to be pivotally attached to the LIDAR sensor and a second end pivotally attached to the at least one cover.

Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: initiating, by a controller onboard the vehicle, a first laser pulse from a first laser device; initiating, by a controller onboard the vehicle, a second laser pulse from a second laser device, wherein the initiating the second laser pulse is based on a phase shift angle; receiving, by the controller onboard the vehicle, first return data and second return data as a result of the first laser pulse and the second laser pulse; interleaving, by the controller onboard the vehicle, the first return pulse and the second return pulse to form a point cloud; and controlling, by the controller onboard the vehicle, the vehicle based on the point cloud.

Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: receiving, by the controller, first return data detected by a first detector of a lidar device as a result of a first laser pulse or chirp; receiving, by the controller, second return data detected by a second detector of the lidar device as a result of a second laser pulse or chirp; combining, by the controller, the first return data and the second return data to form a point cloud; and controlling, by the controller, the vehicle based on the point cloud.

Abstract: Systems and methods in a vehicle involve transmitting light with an initial polarization from a lidar system, and controlling an external compensator, external to the lidar system, or an internal compensator within the lidar system to change the initial polarization of the light to a new polarization of the light. The method also includes receiving reflected light resulting from reflection of the light from one or more objects, and obtaining information about the one or more objects based on the reflected light.
