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 stereovision principles or depth-from-focus principles by one or more image detectors.

Abstract: Techniques described herein generally include methods and systems related to cache partitioning in a chip multiprocessor. Cache-partitioning for a single thread or application between multiple data sources improves energy or latency efficiency of a chip multiprocessor by exploiting variations in energy cost and latency cost of the multiple data sources. Partition sizes for each data source may be selected using an optimization algorithm that minimizes or otherwise reduces latencies or energy consumption associated with cache misses.

In some example embodiments, individual segments may be stored on more than one peer machine and/or an individual peer machine may not receive all of the segments associated with the file.

Abstract: Technologies are generally described for concurrent activation of multiple illumination sources to analyze a sample. A controller may be configured to activate the illumination sources substantially simultaneously, where a current or voltage of each activated illumination source is modulated at a different frequency by respective circuit drivers of the controller. Each activated illumination source may be configured to illuminate the sample with light at a different emission wavelength, and one or more detectors may be configured to detect a composite signal from the sample in response to the illumination. The composite signal may include multiple returned signals, where each returned signal corresponds to light emitted from one of the activated illumination sources at a respective emission wavelength. One or more filters, each associated with a respective modulation frequency of one activated illumination source, may be configured to extract each returned signal from the composite signal for analysis.

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.

A server computing device may generate and send a compositing flow to the intermediary computing device. The compositing flow may comprise model identifiers and model rendering information. The intermediary computing device may retrieve models identified in the compositing flow from the model store, and provide the identified models and model rendering information to a Graphics Processing Unit (GPU) for rendering. The GPU may render graphics for delivery via a network to a client device.

Abstract: Techniques described herein generally relate to a task management system for a chip multiprocessor having multiple processor cores. The task management system tracks the changing instruction set capabilities of each processor core and selects processor cores for use based on the tracked capabilities. In this way, a processor core with one or more failed processing elements can still be used effectively, since the processor core may be selected to process instruction sets that do not use the failed processing elements.

Abstract: Technologies are described for indicating a geographic origin of a digitally-mediated communication relative to a location of a recipient by presenting the indication in an augmented reality scene. For example, an augmented reality scene can be presented to the recipient. The geographic origin of an incoming digital communication may be determined and a relative location of the origin with respect to the recipient's location may be computed. A format for presenting the relative location may be derived from the digital communication and the geographic origin. The augmented reality scene may be updated with the relative location based on the derived format.

Abstract: Technologies related to multiple variable coverage memory for database indexing are generally described. Disclosed methods may be performed to implement high-speed database access to digital service provider customer data as the digital service provider builds an optimized index for a database. Initially, the digital service provider may maintain an appropriate level of service by keeping a relatively slow performing, basic index in a relatively high performance first memory. As the digital service provider builds the optimized index, the digital service provider may maintain the appropriate level of service by gradually shifting from use of the first memory to the use of a relatively lower performance second memory.
