Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a sensor data gathering, threshold exceedance determination, and alert generation mobile device communication system. One of the methods includes obtaining information associated with sensing instruments monitoring physical characteristics of an environment. Values associated with physical characteristics are determined to have exceeded respective thresholds using the obtained information. Alert information describing the values is generated in response to the determination.

Abstract: The operation of a machine can be controlled by performing reconciliation using a cluster of nodes. In one example, a node can receive parent timestamped data from a parent dataset and child timestamped data from child datasets that are children of the parent dataset in a hierarchical relationship. The parent timestamped data and the child timestamped data can relate to an operational characteristic of the machine. The node can generate computer processing-threads. Each computer processing-thread can solve one or more respective reconciliation problems between a parent data point that has a particular timestamp in the parent timestamped data and child data points that also have the particular timestamp in the child timestamp data to generate a reconciled dataset. An operational setting of the machine can then be adjusted based on the reconciled dataset.

Abstract: A fluid pump includes a housing defining a cavity. An end plate is disposed within the cavity and divides the cavity into a gear section and an end section. A gear set is disposed within the gear section and comprises at least one gear rotatable about an axis. The end plate is movable longitudinally along the axis for compressing the gear set. A channel is in fluidic communication with the end section for supplying a fluid to the end section to force the plate toward the gear set.

Abstract: A system for separating contaminants from an airstream, including a centrifugal fan and housing; a contaminant containment vessel mounted to an outer surface of the housing; and a diverter in the airstream downstream of the fan and within the housing, the diverter being configured to separate a portion of the airstream from a remainder of the airstream, accelerate the portion of the airstream towards the containment vessel, and thereafter guide the portion of the airstream towards the remainder of the airstream. The diverter preferably does not negatively impact the rated performance of the fan, such that a performance of the system is not measurably different than the rated performance of the fan and housing combination. The diverter may accelerate contaminants entrained in the airstream toward the containment vessel, thereby separating the contaminants from the airstream.

Abstract: A system for manipulating engine exhaust gases away from inhabited areas comprises an air pressurization system coupled in fluid communication to a housing. The housing is adapted to reside adjacent a terminal portion of an exhaust pipe so that pressurized air injected into the housing entrains the exhaust gases and disperses them from the housing.

Abstract: An inlet and/or outlet air hood comprising vertical storm louvers is provided that is particularly well suited for use with on a Mobile Offshore Drilling Unit and other marine vessels, although its use is not so limited. The hood may comprise a basic cube shape, which affords a smaller projected footprint than conventional round- or mushroom-shaped hood and may incorporate an internal flow shaper, such as an inlet/outlet bell, to reduce airflow resistance. In addition, the hood may be configured to incorporate an internal valve or baffle to create a watertight closure.

Abstract: The present invention relates to an apparatus to transfer liquid from an industrial, rigid liquid package. The apparatus of the present invention is a hollow tube in a U configuration. One leg of the U is inserted into the bung or hole in the top of a rigid liquid package. The section of the apparatus that is inserted into the liquid package is shapes so as to ensure that fluid from the container can enter the hollow apparatus. The apparatus is removably affixed to a rigid liquid package. The apparatus includes a counter-weight which inhibits tipping of the container as it is emptied as well as a configuration which facilitates the removal of substantially all liquid for the rigid liquid package via a fluid pump connected to the apparatus.
