Updating one or more databases based on dataflow events
Database environments may choose to schedule complex analytics processing to be performed by specialized processing environments by caching source datasets or other data needed for the analytics and then outputting results back to customer datasets. It is complex to schedule user database operations, such as running dataflows, recipes, scripts, rules, or the like that may rely on output from the analytics, if the user database operations are on one schedule, while the analytics is on another schedule. User/source datasets may become out of sync and one or both environments may operate on stale data. One way to resolve this problem is to define triggers that, for example, monitor for changes to datasets (or other items of interest) by analytics or other activity and automatically run dataflows, recipes, or the like that are related to the changed datasets (or other items of interest). |

Embodiments of the present invention provide systems, methods, and computer storage media for latent summarization of a graph. Structural features can be captured from feature vectors associated with each node of the graph by applying base functions on the feature vectors and iteratively applying relational operators to successive feature matrices to derive deeper inductive relational functions that capture higher-order structural information in different subgraphs of increasing size (node separations). Heterogeneity can be summarized by performing capturing features in appropriate subgraphs (e.g., node-centric neighborhoods associated with each node type, edge direction, and/or edge type). Binning and/or dimensionality reduction can be applied to the resulting feature matrices. The resulting set of relational functions and multi-level feature matrices can form a latent summary that can be used to perform a variety of graph-based tasks, including node classification, node clustering, link prediction, entity resolution, anomaly and event detection, and inductive learning tasks. |

Method and apparatus for machine monitoring with continuous improvement of a predictive maintenance database
An apparatus continually monitors predictive maintenance information and analyzes incoming measurements resulting in recommendations for improving setup information, such as machine information and measurement configurations. Smart sensors generate sensor signals corresponding to the parameters of a machine and a transducer converts the sensor signals into digital sensor data, which is stored into memory. An analyzer determines current operating characteristics of each machine and runs an improvement cycle in which it calculates new setup information. For example, the analyzer may calculate a new alert limit, which is a new measurement configuration that may be saved in the database as a new stored measurement configuration replacing an old measurement configuration. The analyzer may also calculate new machine information. For example, the analyzer may identify features in a frequency spectrum that are characteristic of a particular geartrain that is different from the geartrain identity provided in the predictive maintenance database. The analyzer may automatically change the identity of the geartrain in the predictive maintenance database, or it may suggest the change to the operator. The analyzer also runs an analysis cycle during which current operating conditions of each machine are determined and signals are issued based on the current operating conditions. |

Diffractive optical elements with asymmetric profiles
In an optical display system that includes a waveguide with multiple diffractive optical elements (DOEs), gratings in one or more of the DOEs may have an asymmetric profile in which gratings may be slanted or blazed.

Launch speed multiplier
An adapter cage is provided for a compressed gas launcher to multiply launch velocity. Kinematics of wheels integral to the adapter cage results in a doubling of the pusher plate velocity as that motion is imparted on a light-weight launch vehicle. The wheels of the adapter cage can press against the launch vehicle and the wheels are pressed against the walls of the launcher for employing friction at the interface of the wheels and the inner surface of the launcher to transfer motion to force out a muzzle cap of the launcher and to enable launch of the launch vehicle. |

Airgun with selective bypass from high pressure reservoir to firing pressure reservoir
An airgun has a high pressure reservoir for providing a pressurized motive gas to a breech to fire a projectile. A regulator is intermediate the high pressure reservoir and a downstream firing pressure reservoir for providing a consistent regulated pressure of the motive gas in the firing pressure reservoir. The airgun includes a bypass line for selectively connecting the high pressure reservoir to the firing pressure reservoir, independently of the regulator. Thus, an operator can select a firing of the airgun with either a regulated gas pressure in the firing reservoir or the pressure of the high pressure reservoir. |

Process cooling rod
A process heat exchange rod for cooling or heating liquids in a process vessel. The rod may have a linear form and extend downward through an upper wall of the process vessel into proximity with the lower floor. The rod internally defines a circulatory flow path for the heat exchange medium, including an outer jacket and a flow diverter having a central through bore and external helical flutes. Heat exchange medium travels down through the central through bore and then back up through helical grooves formed between the flow diverter and the outer jacket, or vice versa. Accurate heating or cooling of the process fluid is attained by modification of the configuration of the heat exchange rod as well as the flow rate and temperature of the heat exchange medium. The components may be injection molded of a polymer, often transparent, having a high heat transfer coefficient. |
