摘要： This disclosure relates to heading misalignment estimation with a portable device and more specifically to estimating misalignment between a portable device having a sensor assembly and a platform transporting the portable device when the platform is undergoing motion having periodic characteristics. In one aspect, a suitable method includes obtaining inertial sensor data for the portable device and determining an effective frequency characteristic of the inertial sensor data representing the motion having periodic characteristics. The inertial sensor data may be processed using the determined frequency characteristic so that a heading misalignment may be estimated between the heading of the portable device and the platform.

摘要： Systems and methods are disclosed for determining a navigational constraint for a portable device using an optical sensor. The navigational constraint may be used to supplement other navigational solutions or may be used independently. The optical sensor may capture a plurality of samples to be processed to determine the constraint. Determining the constraint may include any or all of determining a context for usage, distinguishing usage modes, estimating an orientation of the portable device, determining an absolute and/or relative elevation, determining a direction of motion and determining a speed of the portable device from the samples.

摘要： Anchor points associated with point of sale information may be ordered by segmenting a trajectory derived from sensor data defined by adjacent turns to generate candidate links for each segment from which possible paths for the trajectory are derived. Each derived possible path may be scored with a multi-objective function using a global optimization algorithm to select a solution path from the derived possible paths that may be used to order a plurality of anchor points.

摘要： The navigation solution of a portable device may be enhanced using map information. Sensor data for the portable device may be used to derive navigation solutions at a plurality of epochs over a first period of time. Position information for the device may be estimated at a time subsequent to the first period of time using the navigation solutions. Map information for an area encompassing a current location of the portable device may also be obtained. Multiple hypotheses regarding possible positions of the portable device may be generated using the estimated position information and the map information. By managing and processing the hypotheses, estimated position information for at least one epoch during the first period of time may be updated. An enhanced navigation solution for the at least one epoch may be provided using the updated estimated position information.
