  • Patent number: 11373461
    Abstract: A method for monitoring extra off-duty time intervals of a driver includes: obtaining on-duty time intervals and off-duty time intervals of a driver; and scanning the off-duty time intervals to identify extra off-duty time intervals having a length more than a second minimum length and less than a first minimum length, any identified extra off-duty time intervals being subtracted from a predefined threshold. If the threshold is greater than 0, a workshift reset time interval is analyzed and it is determined if the workshift reset time interval includes an extra off-duty time interval, which cannot be used as workshift reset time interval. Subsequently the analyzed extra off-duty time intervals are subtracted from the threshold. If the threshold is greater than 0, the workshift reset time interval is analyzed and, the workshift reset time interval is, at least partly, shifted from today to tomorrow to create extra off-duty time interval today.

  • Patent number: 11367207
    Abstract: A farming machine includes one or more image sensors for capturing an image as the farming machine moves through the field. A control system accesses an image captured by the one or more sensors and identifies a distance value associated with each pixel of the image. The distance value corresponds to a distance between a point and an object that the pixel represents. The control system classifies pixels in the image as crop, plant, ground, etc. based on the visual information in the pixels. The control system generates a labelled point cloud using the labels and depth information, and identifies features about the crops, plants, ground, etc. in the point cloud. The control system generates treatment actions based on any of the depth information, visual information, point cloud, and feature values. The control system actuates a treatment mechanism based on the classified pixels.

    Abstract: An industrial vehicle includes a body, an axle pivotally supported by the body, a lateral acceleration sensor determining lateral acceleration applied to the body when the industrial vehicle is turned, an actuator temporally restricting pivoting of the axle while the industrial vehicle is being turned, a vehicle speed limiter limiting traveling speed of the industrial vehicle when the industrial vehicle is turned, and a controller driving the actuator based on the lateral acceleration determined by the lateral acceleration sensor to temporally restrict pivoting of the axle and to limit traveling speed of the industrial vehicle based on the lateral acceleration. In the controller a first lateral acceleration threshold value which is used in judging whether traveling speed of the industrial vehicle should be limited is set larger than a second lateral acceleration threshold value which is used in judging whether pivoting of the axle should be temporally restricted.

  • Patent number: 11267129
    Abstract: An automatic positioning method and an automatic control device are provided. The automatic control device includes a processing unit, a memory unit, and a camera unit to automatically control a robotic arm. When the processing unit executes a positioning procedure, the camera unit obtains a first image of the robotic arm. The processing unit analyzes the first image to establish a three-dimensional working environment model and obtains first spatial positioning data. The processing unit controls the robotic arm to move a plurality of times to sequentially obtain a plurality of second images of the robotic arm by the camera unit and analyzes the second images and encoder information of the robotic arm to obtain second spatial positioning data. The processing unit determines whether an error parameter between the first spatial positioning data and the second spatial positioning data is less than a specification value to end the positioning procedure.

The computing device transmits a set of instructions for the vehicle to move a volume of material from the target location. The computing device receives sensor data describing a depth of the target location, a current volume of material moved from the target location, and a position of the vehicle. The graphical user interface displayed on the computing device is modified to display the current depth of the target location, and the position of the vehicle relative to the target location. The computing device modifies the set of instructions based on the received sensor data and provides the modified set of instructions to the vehicle.
