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). |

The pipe includes segments (T1, T2, T3, TN) joined together by means of connectors, wherein each segment of the pipe has an injector pipe (I1, I2, I3, IN) for injecting fluid into the annulus at a first end of the segment, and a return pipe (R1, R2, R3, RN) for removing fluid from the annulus at a second end of the segment. |

Piercing tool aiming device
A system and for providing a bore sight in a piercing tool. A transmitter emits a magnetic field. The flux lines which emanate along the transmitter axis are substantially straight. A receiver at a remote, target location can detect these flux lines. The receiver and transmitter are oriented such that the substantially straight flux line are along an intended bore path. Then, a piercing tool or other boring tool is oriented along the same path and a bore is created. |

Trajectory control for directional drilling
A method for controlling a drilling trajectory of a wellbore includes computing a position and attitude of a drill bit within a wellbore. The method further includes computing a wellbore trajectory error between (i) the position of the drill bit and a well plan position and (ii) the attitude of the drill bit and a well plan attitude. Further, the method includes determining an inclination set-point change command and an azimuth set-point change command using the wellbore trajectory error. Additionally, the method includes steering the drill bit using the inclination set-point change command and the azimuth set-point change command. |

Ambidextrous hold open hinge
The present disclosure relates to an ambidextrous hinge. The ambidextrous hinge includes a first knuckle with a first engagement feature, a second knuckle with a second engagement feature, and a third knuckle movably coupled between the first knuckle and the second knuckle. The third knuckle includes a third engagement feature that engages the first engagement feature to cause the ambidextrous hinge to lock in a first open position when used as a first swing hinge. The third knuckle includes a fourth engagement feature that engages the second engagement feature to cause the ambidextrous hinge to lock in a second open position when used as a second swing hinge. |

Door assembly for a telecommunications chassis with a combination hinge structure
A hinge assembly for pivotally coupling a door to a telecommunications chassis includes a hinge structure configured to attach the door to the telecommunications chassis, the hinge structure defining a door pivot point and a hinge pivot point that is spaced from the door pivot point, wherein a door coupled by the hinge structure to the telecommunications chassis can pivot with respect to the hinge structure independent of a pivoting motion of the hinge structure with respect to the telecommunications chassis, wherein the hinge structure further defines at least a portion of a pivot limiting structure spaced from the hinge pivot point, the portion of the pivot limiting structure defined by the hinge structure being configured to interact with the telecommunications chassis in limiting the pivoting motion of the hinge structure. |

Rear emergency handle
An emergency mechanism for manually opening a powered door that includes a hold-close latch that holds the door in a closed position. During the manual operation, a manually operated handle for actuating only the hold-closed latch is manually moved from a non-actuating position to an actuating position, which actuates the hold-close latch to release the door from the closed position. The handle is held in the actuating position until it is moved back to the non-actuating position during a subsequent powered operation, thus allowing a user to move the door to an opened position using both hands. |

Smart latch assembly with window regulator control
A latch assembly for a closure panel of a motor vehicle and corresponding method of operation are provided. The latch assembly includes a latch housing for attachment to the closure panel and contains an actuation group to latch and unlatch the closure panel. An electronic control circuit that has a latch controller is disposed within the latch housing and is coupled to the at least one actuation group. The electronic control circuit includes a motor voltage and current sensing circuit for sensing a motor current and a motor voltage of a remote electric motor disposed remotely from the latch housing. The latch controller monitors and controls the actuation group and determine at least one of a motor rotational position and a motor speed of the remote electric motor based on at least one of the motor current signal and the motor voltage signal and controls the remote electric motor accordingly. |

Magnetically-triggered lock mechanism
A lock mechanism for interengaging two relatively movable components includes a bolt mounted within a first component and interengageable with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended. A magnetically-releasable latch mechanism is positioned to latch the bolt in a retracted position and is mounted for movement between a biased latch engaging position and a latch releasing position in a non-common direction of movement of the bolt. A first magnet is disposed within a trigger being translatable along an axis parallel to a longitudinal axis of the bolt and a second magnet is positioned to displace the latch mechanism to the latch releasing position as the trigger is caused to translate vertically when the first component is in the predetermined position relative to the second component to permit displacement of the bolt to the extended position. |
