    Abstract: Systems and methods for determining a swing angle of a swing boom of a vehicle are provided. Sensor data is received from sensors disposed on a swing boom and a body of a vehicle. It is determined whether the swing boom is static or moving relative to the body based on the sensor data. In response to determining that the swing boom is static, the received sensor data is corrected based on an observed swing angle and an estimated swing angle is calculated based on the corrected sensor data. In response to determining that the swing boom is moving, the estimated swing angle is calculated based on the received sensor data. The estimated swing angle is output.

    Abstract: A laser measuring system including first and second laser base stations (102-A, 102-B or 102-C) and a laser receiver (104) is provided. The laser receiver detects a first laser signal from the first laser base station. Location information associated with the first laser base station is extracted from the detected first laser signal. The laser receiver detects a second laser signal from the second laser base station. Location information associated with the second laser base station is extracted from the detected second laser signal. A position of the laser receiver is determined based on the extracted location information associated with the first laser base station and the extracted location information associated with the second laser base station.

    Abstract: A method for agricultural refill planning determines a refill time and access point for a mobile storage device (e.g., a seed tender) to refill an agricultural distribution device (e.g., planter) with agricultural material (e.g., seed). The refill time and access point are selected so that excess time is not lost and areas, such as planting fields, are not adversely affected by movement of the agricultural distribution device or the mobile storage device.

    Abstract: A valve switch unit has a detector configured to detect an input, such as current, from a machine controller. The valve switch unit also has a switching circuit configured to switch control of the one or more valves an automatic controller to the machine controller if the input from the machine controller exceeds a predetermined threshold. When the current detected exceeds the predetermined threshold, the circuit switches control from the automatic controller to the machine controller. In a similar fashion, when the current falls below the predetermined threshold, the circuit switches control back to the automatic controller.

    Abstract: A material independent mass flow sensor is used to generate signals that can be used to calculate mass flow of grain harvested by a combine. A method for determining a mass of material includes the steps of receiving data from a three-measurement transducer and determining an angular center of mass location of an object based on the data from the three-measurement transducer. A coefficient of friction of the object is determined. A velocity of the object is determined. A mass of the object is determined. The mass of the object can be determined based on the angular center of mass location of the object, the coefficient of friction of the object, and the velocity of the object.
