A system for displaying information to an operator of a machine comprises a head tracking system and a projection system. One system for displaying information uses a projection system and a see-through display to present two-dimensional images to an operator. One system uses a projection system and a see-through display to present three-dimensional images to an operator. One system uses a pair of smart glasses to display information to a user based a direction a user is looking.

A plurality of GNSS satellite signals feeds multiple signal processing engines, each operating in certain processing mode including carrier smoothed pseudorange positioning, precise point positioning (PPP), pseudorange differential (DGNSS), carrier phase differential (RTK). Each processing engine (or processing thread of the same engine) runs the same unified numerical algorithm and uses the same or different sets of parameters. All engines can use the same set of signals, or the set of signals can be split into non-intersecting subsets, or the set of signals can be split into the overlapping subsets. Each engine produces estimates of certain parameters, namely carrier phase ambiguities and ionospheric delays for each satellite. These estimates are then combined into a resulting estimate which in turn is used for calculation of the final position reported by the receiver.

A method and system utilizing one or more agricultural drones in combination with agricultural equipment, e.g., an agricultural boom sprayer, to evaluate the crops being farmed, and to improve the real-time delivery and dispensing of liquid from the sprayer including monitoring and verifying that the liquid is being dispensed correctly and/or in accordance with a desired distribution pattern or level.

A site-aware controller and various sensors determine if objects are located within a safety dome surrounding a machine such as a construction vehicle. The site-aware controller compares data from the various sensors to determine if the machine or independently moveable implements located on the machine are capable of impacting objects within the safety dome and/or travel of the machine into restricted areas. Detection of objects within the safety dome can trigger alerts (e.g., visual and/or audible) to an operator of the machine of a particular situation. Detection of objects within the safety dome can also prevent further movement of the machine or independently moveable implements located on the machine to prevent impacting the objects. The system can also prevent movement of the machine into restricted areas.

On a dozer, a semi-automatic system automatically translates a joystick to control blade elevation and provides an indicator display to guide manual control of blade slope angle. A mechanical linkage operably couples the joystick to an electrical motor. A computational system receives measurements from measurement units mounted on the dozer; calculates estimated values of elevation and slope angle; compares the estimated values to reference values; and calculates error and control signals. Drivers generate a motor drive signal and a display drive signal. In response to the motor drive signal, the electrical motor translates the joystick to control elevation. In response to the display drive signal, the indicator display generates a graphical representation of the status of slope angle. When the operator needs to take manual control, a proximity sensor detects the presence of at least a portion of the operator's hand, wrist, or forearm and disengages automatic control of elevation.

A vehicle guidance system is disclosed where the vehicle includes a steering wheel assembly including a steering wheel and a hub, the hub connected to a steering shaft rotatable about a steering wheel axis within a steering column for steering the vehicle. The vehicle guidance system includes a receiver for receiving a position indication signal, a steering controller for generating a steering control signal based on the position indication signal and a drive assembly to directly drive the steering wheel assembly responsive to the steering control signal. The drive assembly generates a torque about a drive axis to rotate the steering wheel assembly, wherein the drive axis of the drive assembly is coaxial to the steering wheel axis.

An augmented image is generated by capturing a visual image of a site with a digital camera, generating a virtual image or associated information from a digital model of the site, and superimposing the virtual image or associated information on the visual image. To register the digital model with the visual image, a sensor pole is introduced into the field of view, and a combined visual image of the site and an optical target on the sensor pole is captured. The position and orientation of the sensor pole with respect to the site reference frame are measured by sensors mounted on the sensor pole; the position and orientation of the digital camera with respect to the sensor pole are calculated from image analysis of the optical target on the sensor pole; and the position and orientation of the digital camera with respect to the site reference frame are calculated.

An optimum measurement subset with a specified number of elements is generated from a set of input global navigation satellite system (GNSS) measurements. A design matrix and a weight matrix are generated. Values of a set of coefficients corresponding to the set of input GNSS measurements are calculated. The value of a specific coefficient is calculated as the ratio of the change in value of the at least one target parameter resulting from the change in value of the specific input GNSS measurement to the change in value of the sum of squared residuals resulting from the change in value of the specific input GNSS measurement. The optimum measurement subset is selected based at least in part on the values of the set of coefficients.

An optimum measurement subset with a specified number n of elements is generated from a set of N&#x3e;n weighted input global navigation satellite system (GNSS) measurements. A group of trial measurement subsets is generated by removing a different individual weighted input GNSS measurement from the set. A value of accuracy criterion for a target parameter is calculated for each trial measurement subset, and the trial measurement subset with the minimum value of accuracy criterion is selected. A new group of trial measurement subsets is generated by removing a different individual weighted GNSS measurement from the previously selected trial measurement subset. A value of accuracy criterion is calculated for each new trial measurement subset, and a new trial measurement subset with the new minimum value of accuracy criterion is selected. The process is repeated until the selected trial measurement subset has the specified number n of elements.

Dozers outfitted with manual or electric valves can be retrofitted with a control system for automatically controlling the elevation and orientation of the blade. No modification of the existing hydraulic drive system or existing hydraulic control system is needed. An arm is operably coupled to the existing joystick, whose translation controls the elevation and orientation of the blade. The arm is driven by an electrical motor assembly. Measurement units mounted on the dozer body or blade provide measurements corresponding to the elevation or orientation of the blade. A computational system receives the measurements, compares them to target reference values, and generates control signals. Drivers convert the control signals to electrical drive signals. In response to the electrical drive signals, the electrical motor assembly translates the arm, which, in turn, translates the joystick. If necessary, an operator can override the automatic control system by manually operating the joystick.
