Abstract: Technologies are generally described for coordination of structured light-based image detectors. In some examples, one or more structured light sources may be configured to project sets of points onto the scene. The sets of points may be arranged into disjoint sets of geometrical shapes such as lines, where each geometrical shape includes a subset of the points projected by an illumination source. A relative position and or a color of the points in each geometrical shape may encode an identification code with which each illumination source may be identified. Thus, even when the point clouds projected by each of the illumination sources overlap, the geometrical shapes may still be detected, and thereby a corresponding illumination source may be identified. A depth map may then be estimated based on stereo vision principles or depth-from-focus principles by one or more image detectors.

Abstract: Various embodiments of a scheme of dynamic activation and release of carrier aggregation in an LTE-Advanced system are provided. When transmission need of an LTE-Advanced user is large and the user is within coverage of at least one secondary component carrier, carrier aggregation is activated while a certain amount of resource of each component carrier is preserved to support carrier aggregation. This avoids unnecessary activation and waste due to signaling cost. When the primary component carrier of an LTE-Advanced user has sufficient resource to satisfy transmission need of the user or when the user is not within coverage of at least one secondary component carrier, carrier aggregation is released. This minimizes complex measurement and cost of controlling signals due to multi-carrier scheduling.
