Abstract: Raw dead reckoning data is obtained from an inertial measurement unit (IMU) worn by a user. Drift in the raw data is compensated for by detecting a gait of the user and phase of that gait, and constraining the position of the IMU to lie within corresponding bounds as the IMU moves. The bounds depend on the bodily geometry of the user and the detected gait phase. The raw orientation data of the IMU may be also corrected for drift in a similar way. Gait and gait phase may be detected by sensors in an energy harvester worn around the knee, for example. Drift in the IMU measurements can be compensated for without depending on a GPS signal or on the earth's magnetic field.

Abstract: System and methods for computing true wind and true current are described. True wind estimation occurs through automatic calibration of data obtained from data acquisition devices (102, 114, 116, 118, 120).

Maneuvers are found in data obtained from the data acquisition devices (102, 114, 116, 118, 120) and, if properly calibrated, wind just prior to a maneuver should be the same as measured wind just after the maneuver. If the measured wind values are not equal, the sum of the wind difference over all maneuvers is minimized.

Abstract: A non-scaled, linearly compressed pictographic mapping system is provided for the visual display of information in a navigational aid. Unlike today's road maps which use a point-arc-polygon paradigm, the new mapping uses a non-scaled, linearly-compressed pictographic design that shows roads as linear pictograms. The display has a columnar layout, whereby the descriptive elements are grouped together by type, and displayed one above the other in columns. The maps may also contain icons representing points of interest. In this manner, the mapping paradigm also serves to increase traveler safety, provide navigation assistance during address-less trips, create valuable advertising space and new promotional opportunities, and dramatically increases the travelers' communications and entertainment options.
