Abstract: Embodiments that relate to sharing mixed reality experiences among multiple display devices are disclosed. In one embodiment, a method includes receiving current versions of a plurality of data subtypes geo-located at a keyframe location. A world map data structure is updated to include the current versions, and a neighborhood request including the keyframe location is received from a display device. Based on the keyframe location, an identifier and current version indicator for each data subtype is provided to the device. A data request from the device for two or more of the data subtypes is received, and the two or more data subtypes are prioritized based on a priority hierarchy. Based on the prioritization, current versions of the data subtypes are sequentially provided to the device for augmenting an appearance of a mixed reality environment.

Abstract: A power conversion system is disclosed including a DC bus for receiving DC power, a power converter for converting the DC power to AC power, and a controller. The controller includes an active power regulator for generating a phase angle command signal, a reactive power regulator for generating a voltage magnitude command, and an active power (P) and reactive power (Q) decoupling unit for decoupling interaction between the active and reactive power regulators. The PQ decoupling unit includes an active power compensation element and a reactive power compensation element. The active power compensation element is used for generating a phase angle compensation signal based on a reactive power error signal, to compensate the phase angle command signal. The reactive power compensation element is used for generating a voltage magnitude compensation signal based on an active power error signal, to compensate the voltage magnitude command signal.

Abstract: Photographs of an object may be oriented with respect to both the geographic location and orientation of the object by registering a 3D model derived from a plurality of photographs of the objects with a 2D image of the object having a known location and orientation. For example, a 3D point cloud of an object created from photographs of the object using a Photosynth™ tool may be aligned with a satellite photograph of the object, where the satellite photograph has location and orientation information. A tool providing scaling and rotation of the 3D model with respect to the 2D image may be used or an automatic alignment may be performed using a function based on object edges filtered at particular angles. Once aligned, data may be recorded that registers camera locations for the plurality of photographs with geographic coordinates of the object, either absolute latitude/longitude or relative to the object.

Abstract: This document describes techniques for creating three-dimensional models of image collections using a network-accessible (e.g., cloud-based) computation service, rather than a client computing device. In some instances described below, the computation service performs at least a portion of the operations for creating these models in parallel.
