Abstract: A method for controlling a dual fuel engine system includes estimating a total indicated engine load, where the total indicated engine load is based on a sum of a measured engine power and a power loss estimate. The method further includes determining a total fueling amount based on an engine speed and the total indicated engine load, where the total fueling amount includes a gas fueling amount and a diesel fueling amount. The method also includes controlling the dual fuel engine system using the total fueling amount.

Abstract: A method for controlling a dual fuel engine system includes determining a friction power loss amount of an internal combustion engine of the dual fuel engine system, where the friction power loss amount is based on an engine speed of the internal combustion engine and a friction torque estimate. The method also includes determining an accessory power loss amount of a power of the internal combustion engine, where the accessory power loss amount is based on the engine speed and an accessory torque estimate. The method further includes estimating a net engine power amount based on the accessory power loss amount and a brake power amount of the internal combustion engine, estimating an indicated diesel power, and estimating, based on the estimated net engine power, a first indicated engine power and a first gas power.

Abstract: A spreader for spreading a material including at least one pair of rotating discs having a plurality of generally radially oriented blades attached thereon for disbursing the material in a pre-selected pattern. The discs are rotatably positioned below an end of a funnel unit to receive material passing through the funnel units. The material, as it passes through the funnel units, is directed to a predetermined impact region on each of the rotating discs by a corresponding pair of deflecting vanes integrally fit and movably attached within each funnel of the pair of funnel units. Each deflecting vane is selectably movable by a corresponding actuator from a first position to a second position while the spreader is operating.

Abstract: A spreader for spreading a material includes a first hopper for receiving a first material, and a pair of first dispensers, each first dispenser of the pair of first dispensers defining a corresponding first spread section for dispensing the first material from the first hopper. A second hopper is selectably receivable in the first hopper, the second hopper for receiving a second material, and a pair of second dispensers, each second dispenser of the pair of second dispensers defining a corresponding second spread section for dispensing the second material from the second hopper. Each second dispenser of the pair of second dispensers is selectively operable independently of each first dispenser of the pair of first dispensers.

Abstract: A global navigation satellite system (GNSS) based control system is provided for positioning a working component relative to a work surface, such as an agricultural spray boom over a crop field. Inertial measurement unit (IMU) sensors, such as accelerometers and gyroscopes, are mounted on the working component and provide positioning signals to a control processor. A method of positioning a working component relative to a work surface using GNSS-based positioning signals is also disclosed. Further disclosed is a work order management system and method, which can be configured for controlling the operation of multiple vehicles, such as agricultural sprayers each equipped with GNSS-based spray boom height control subsystems. The sprayers can be remotely located from each other on multiple crop fields, and can utilize GNSS-based, field-specific terrain models for controlling their spraying operations.

Abstract: A method of regulating the operation of a vehicle axle system, the vehicle axle system including at least one adjustable axle having at least one axle cylinder and a steering assembly including at least one steering cylinder connected thereto, an axle management system including a microcontroller having a microprocessor, a memory, and a sensor. The method includes receiving, by the axle management system, at least one desired axle position and at least one measured axle position, from at least one sensor. The method also includes determining, if the measured axle position is within a predetermined tolerance threshold of the desired axle position and regulating the position of the at least one adjustable axle.

As the attributes are entered into the system, faces are automatically generated based on those attributes, which eases creation of lots within subdivisions.

Abstract: A CAD/GIS system that dynamically updates planar topologies through incremental updating techniques. Rather than batch processing all of the changes to every geometrical feature in a given site map, the changes are made in incremental fashion and only enclosures or faces/parcels that are affected by changes are updated.
