Dynamic multi-view rendering for autostereoscopic displays by generating reduced number of views for less-critical segments based on saliency/depth/eye gaze map
A segmented 3D multi-view image generator generates fewer multi-view view images for partitions having less salient features. Saliency values are calculated based on a depth map and image processing of the input image. The saliency values are compared to thresholds to map pixel locations to first, second, and third partitions. First, second, and third segmented images are created from the input image using a partition map. A multi-view generator uses the depth map and viewer eye locations to generates 28 view images from the first segmented image, 14 unique view images from the second segmented image that are replicated to 28 view images, and 7 unique view images from the third segmented image that are replicated to 28 view images. The view images for each segment are interlaced to generated interlaced segmented images that are then integrated together into a single 3D image that drives a 28-view autostereoscopic display. |

Internet-based proxy service for responding to server offline errors
A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The proxy server transmits the request to the origin server. Responsive to determining that the origin server is offline, the proxy server determines whether the requested resource is available in cache. If it is in cache, the proxy server retrieves the requested resource from the cache and transmits the requested resource to the client device. The proxy server also transmits an offline browsing cookie to the client device for the domain such that when a subsequent request is received from the client device for a resource of the domain that includes the offline browsing cookie, a cached version of the requested resource will be served instead of querying the origin server. |

Systems and method for automated package-data asset generation
A global architecture (GLP), as disclosed herein, is based on the thin server architectural pattern; it delivers all its services in the form of web services and there are no user interface components executed on the GLP. Each web service exposed by the GLP is stateless, which allows the GLP to be highly scalable. The GLP is further decomposed into components. Each component is a microservice, making the overall architecture fully decoupled. Each microservice has fail-over nodes and can scale up on demand. This means the GLP has no single point of failure, making the platform both highly scalable and available. The GLP architecture provides the capability to build and deploy a microservice instance for each course-recipient-user combination. Because each student interacts with their own microservice, this makes the GLP scale up to the limit of cloud resources available—i.e. near infinity. |

Network problem node identification using traceroute aggregation
Computer-aided identification of a potential problem node in a network. As part of data collection, a computing system gathers telemetric and trace route data for communications that occur within a network. Upon detecting that a performance problem has occurred within the network, multiple communications that occurred around the time of the performance problem are identified. Then, the trace route data for these multiple communications are aggregated. The aggregated data may then be used to identify a potential problem network node within the network. The identity of the potential problem network node (and potentially observed telemetry for that network node) may then be communicated to an entity that is affected by the performance problem. This may allow the entity to understand which network node is causing the problem and thus take appropriate remedial measures. |

After receiving the BGP message indicating a DDoS attack is in progress, the DDoS attack mitigation platform automatically takes steps to mitigate the DDoS attack without further manual intervention. Consequently, the targeted computer system recovers more quickly and begins to respond to legitimate network requests sooner relative to prior approaches. |

Symptom detection using behavior probability density, network monitoring of multiple observation value types, and network monitoring using orthogonal profiling dimensions
One network monitoring system maintains both information regarding historical activity and emergent activity of the network. Comparison of recent activity of the network with historical activity allows the system to determine whether recent network activity is within the realm of normal. The system maintains data structures representing a p.d.f. for observable values of network parameters. Such data structures are maintained both for historical and for emergent activity of the network. Recent activity can be compared with the p.d.f. for historical activity to aid in determining whether that recent activity is within the realm of normal. Network activity not within the realm of normal can include values of observable network parameters too high or too low to be consistent with historical activity of the network, or other values too unlikely to be consistent with historical activity at the network.Another network monitoring device includes data structures for maintaining information regarding historical activity of a network and emergent activity of a network. Those data structures include multiple types of observable values as well as multiple types of combinations of multiple observable values. The network monitoring device maintains those data structures including information regarding historical activity of a network and emergent activity of a network only for those source/destination pairs, and only for those nodes, for which maintaining that information would be substantially meaningful.Yet another network monitoring system includes data structures for maintaining information regarding historical activity of a network and emergent activity of a network. Those data structures include observable values for multiple profile dimensions, including source/destination address, application, location, and time. The data structures also include observable values for combinations of more than one of those multiple profile dimensions, including, e.g., (source address)×(application), and the like. It is expected that only a relatively sparse set of combinations of more than one of those multiple profile dimensions would have meaningful information associated therewith. The network monitoring system maintains those data structures only for those combinations of more than one of those multiple profile dimensions for which maintaining that information would be substantially meaningful. |

Filter
A circuit comprising: a passive reactive component; and an active circuit, the active circuit arranged to increase the ac voltage difference across the reactive component by changing the current at an input to the reactive component and the current at an output of the reactive component by equal and opposite amounts.

Optical power that has been stored inside the laser resonator is then dumped out of the laser in a single, very-high power pulse. |

High mobility strained channels for fin-based NMOS transistors
Techniques are disclosed for incorporating high mobility strained channels into fin-based NMOS transistors (e.g., FinFETs such as double-gate, trigate, etc), wherein a stress material is cladded onto the channel area of the fin. In one example embodiment, a germanium or silicon germanium film is cladded onto silicon fins in order to provide a desired tensile strain in the core of the fin, although other fin and cladding materials can be used. The techniques are compatible with typical process flows, and cladding deposition can occur at a plurality of locations within typical process flow. In various embodiments, fins may be formed with a minimum width (or later thinned) so as to improve transistor performance. In some embodiments, a thinned fin also increases tensile strain across the core of a cladded fin. In some cases, strain in the core may be further enhanced by adding an embedded silicon epitaxial source and drain. |
