20080259730 | Method and apparatus for ultrasonic sensing - A distance and temperature sensing unit is used on paving vehicles. The unit has a first set of range sensors of a first diameter and a second set of range sensors of a second diameter. The unit calculates a weighted average distance to a road surface based on ranges measured by the multiple sensors. The unit also has a temperature sensor on a temperature bar. The bar is affixed to the unit by a flexible connection preventing break-off when the bar encounters obstacles, like the road surface, while the paving vehicle is moving. | 10-23-2008 |
20150041238 | VEHICLE GUIDANCE SYSTEM - 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. | 02-12-2015 |

20130261902 | Automatic Control of a Joystick for Dozer Blade Control - 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. | 10-03-2013 |
20130342393 | Selection of a Subset of Global Navigation Satellite System Measurements Based on Relation between Shifts in Target Parameters and Sum of Residuals - 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. | 12-26-2013 |
20130342396 | Selection of a Subset of Global Navigation Satellite System Measurements Based on Prediction of Accuracy of Target Parameters - An optimum measurement subset with a specified number n of elements is generated from a set of N>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. | 12-26-2013 |
