Abstract: Determining remaining vehicle range by adjusting measured estimates on the fly accounting for road effects, the state of vehicle accessories, and other conditions.

Abstract: Estimating a vehicle's driving range by combined processing of measured and calculated range data. A measured range it is adjusted to account for processes not included in the original measurements. These adjustments may include changes in road surface, terrain elevation, aerodynamic drag, or other losses. The resulting model is thus relative to the conditions used in quantifying vehicle range by calculating contributions that either penalize or enhance the measured range. This method is implemented in a software system that can also provide real-time display of the range for both a single trip or a contour that illustrates what the range is for all directions.

Abstract: A cellular network configuration tool is described that performs frequency assignments for use in a cellular network. The channels are assigned in accordance with input configuration data such as a channel separation matrix, geographic data, and requested channel assignments for each sector included in the cellular network being configured. The configuration is performed in accordance with predetermined constraints and criteria and quality of service input. The tool uses frequency assignment techniques to perform the channel assignments in accordance with varying constraints and criteria. A penalty function is used to determine a figure of merit for a particular set of frequency assignments.

Abstract: A system and method for wireless network planning utilizing raster data, stored and manipulated in raster data planes (204-212) and vector data (522) stored and manipulated in vector data planes (528-532). The invention increases the accuracy of network planning by simultaneously utilizing vector data planes (528-532) and raster data planes (204-212) to perform computations using vector features contained within map pixels (604). The disclosed method makes it possible to perform accurate computations such as propagation loss to vector points (602) contained within map pixels (604). Accuracy is further increased because other characteristics such as received power, elevation, and best server can be computed to the vector features rather than processing them with traditional raster resolutions.

Abstract: A method and system for generating three-dimensional antenna patterns from two-dimensional cross sections. The method involves an estimate (1006), on a given vertical plane, obtained by rotating a gain value (1010) from the front of the vertical pattern using the horizontal pattern (1004) as a weight; a second estimate, which could be on a separate vertical plane, obtained by rotating a gain value (1014) from the back of the vertical pattern, and a final estimate (1206) obtained by connecting the first two estimates across their respective planes. The invention yields smooth reasonable surfaces (1704) that satisfy the vertical and horizontal boundary conditions, exhibits no mathematical artifacts, and improves the accuracy of propagation calculations of radio frequency signals. The method is implemented in a software system (1812) that provides interactive analysis and visualization capabilities for antenna patterns in three dimensions.
