Abstract: A method for visual inertial odometry (VIO)-aided global positioning is described. The method includes updating an extended Kalman filter (EKF) state including a current pose and a sliding window of multiple prior poses. The sliding window includes poses at a number of most recent global positioning system (GPS) time epochs. Updating the EKF includes updating an EKF covariance matrix for the prior poses and the current pose in the EKF state. The method also includes determining, at a GPS epoch, a relative displacement between each of the updated prior poses and the current pose. The method further includes determining an error covariance of each of the relative displacements based on cross-covariances between each of the updated prior poses and the current pose in the EKF covariance matrix. The method additionally includes using the relative displacements and the error covariances to fuse pseudorange measurements taken over multiple epochs.

Furthermore, further recesses are provided on that side which faces the stator in the transition zones between the magnetically differently polarized sections of the magnet segments, said recesses serving as inner detached pole portions.

Abstract: Techniques for use in determining redress measures for a television (TV) service outage based on impact analysis are described. A TV service outage may be associated with a TV system apparatus including a TV user interface (UI). In one illustrative example, one or more subscribers impacted by the TV service outage are determined. An impact score is determined for each one of the subscribers. A redress measure for each one of the subscribers is then determined in accordance with their corresponding impact scores. An impacted subscriber and/or an impact score may be determined based at least in part on subscriber TV usage data or subscriber TV UI usage data.

The repeated aspiration and ejection through the nozzle sipper effectively mixes the reagents and the template in an automated or semi-automated fashion.

Abstract: An intraoral mandibular advancement device for treatment of sleep disorders includes a maxillary appliance having a protrusive element distending from the anterior portion of the maxillary appliance, and a mandibular appliance having a polymeric shell with recesses to receive and removably engage the mandibular teeth. A lingual spacer extends posteriorly from the anterior portion of the mandibular appliance to contact the anterior aspect of the protrusive element and thereby cause mandibular advancement. An anterior stop extends upward from the occlusal surface of the anterior portion of the mandibular appliance to contact the anterior portion of the maxillary appliance and thereby maintain separation between the anterior teeth and provide a mechanism, by way of its vertical reduction, to reinstate posterior contacts as the jaw moves forward. Posterior stops on the occlusal surface of the posterior portions of either appliance maintain separation between the posterior teeth.
