Abstract: An adjustable insertion assembly for an electrochemical sensor includes an electrode holder to receive the sensor, having a distal aperture to permit process fluid to contact the sensor. A receptacle slidably receives the holder, for a sliding range of motion extending from fully inserted to fully retracted positions. An open distal end portion of the receptacle extends through a wall of a process fluid vessel, so that the aperture is open to the process fluid when fully inserted, and closed when fully retracted. A leverage member is releasably movable relative to the receptacle, and moves with a captured extension. An abutment of the receptacle engages the extension so that movement of the leverage member in opposite directions alternately clamps and releases the electrode holder relative to the receptacle to substantially prevent and permit movement at substantially any point within the range of movement.

Abstract: A computer system and method removes or changes graphic content not discernable from the rendering tree stored in memory. The content modified depends on its redraw area in a physical monitor or a pane, which is contained within a layout in a frame. One or more frames are defined as part of a logical monitor. A physical monitor may have one or more logical monitors. Each redraw area is determined and graphic content is modified with different graphic having a memory use less than the original graphic that is determined not to be discernable based on the resolution and zoom information.

Abstract: A refrigerated container system is described that includes a wireless personal area network (WPAN) including a plurality of wireless sensor nodes and a coordinator node through which the sensors provide sensor data to a controller for the refrigerated container system. The wireless sensors and the coordinator incorporate a variety of features that ensure efficient utilization of battery life by preventing unintended pairing of sensors with other WPANs and excessive sensor signal processing arising from door chatter. Finally, pairing is performed without pressing a button on the wireless door sensor. Instead, the sensor's magnetic reed switch is enlisted to detect swiping of a magnet by a user to enter a pairing mode.

Abstract: Systems and methods for determining concentrations of components of a multiphase fluid. A first flowmeter receives a fluid flow and generates measurements of the fluid flow. After at least partially separating the fluid flow into mixtures of its components, second and third flowmeters generate measurements of the mixtures. A data processing apparatus operatively coupled to the flowmeters receives the measurements and determines concentrations of the components of the fluid flow. In an embodiment, the measurements are mass flow and density readings.

Abstract: A multi-phase process fluid is passed through a vibratable flowtube. Motion is induced in the vibratable flowtube. A first apparent property of the multi-phase process fluid based on the motion of the vibratable flowtube is determined, and an apparent intermediate value associated with the multi-phase process fluid based on the first apparent property is determined. A corrected intermediate value is determined based on a mapping between the intermediate value and the corrected intermediate value. A phase-specific property of a phase of the multi-phase process fluid is determined based on the corrected intermediate value.

Abstract: A manufacturing execution system (MES) for selectively controlling the display of MES content. The MES displays a first view with data about a first aspect of an industrial process and determines whether the user is authorized to view data about a second aspect of the industrial process related to the first. An inactive informational display item is generated when the user is not authorized to view the data about the second aspect. The informational display item provides a visual indication of the relationship between the first and second aspects and is non-selectable for navigating to another display. An active navigational display item is generated when the user is authorized to view the data about the second aspect. The navigational display item provides a visual indication of the relationship between the first and second aspects and is selectable for navigating to a second view including data about the second aspect.

Abstract: A manufacturing execution system (MES) for providing an indication of the performance of the line. The MES includes a configuration module for modeling entities and lines containing the entities. The MES also includes a runtime module configured to determine the entities on the line whose production can be extrapolated to evaluate the performance of the line. In some cases, the MES determines which of the entities on the line limits the performance of the line; in other cases, the MES determines which of the entities has a production amount that best represents that of the line. The MES is operatively connected to field inputs associated with the entities that provide production data for the entities. Using the production data for the entities chosen to represent the line, the MES generates production metrics representative of the performance of the line and displays them to MES users.
