Abstract: A computer-implemented method includes receiving, by a programmable logic controller coupled to a control unit associated with a vessel containing oil and water within a Gas-Oil-Separation Plant (GOSP), a first signal representing a first capacitance measurement detected by a first capacitance probe attached to the vessel at a first elevation. Determining whether an alarm condition is met by detecting whether the first capacitance measurement is higher than a first predetermined maximum limit, or a rate of change (ROC) of the first capacitance measurement is higher than a first predetermined ROC limit, or both. If the alarm condition is met, sending an alarm signal indicating that an upcoming process upset has been detected within the vessel. Subsequent alarms at higher elevations, if available, can alarm operators if the emulsion layer thickness continues to increase and further mitigation measures are required (such as higher demulsifier dosage, skimming of emulsion layer, etc.).

Abstract: A multicolor thermal printer comprising a controller, a thermal printhead, multicolor thermal paper, a monochrome lightness sensor, and a calibration subsystem is described. The calibration subsystem prints a calibration target that is scanned by the monochrome lightness sensor to determine if color crosstalk is present. If color crosstalk is present, the calibration subsystem decreases the contone range of affected colors and saves the new calibration settings.

The color table includes a plurality of nodes, and each node corresponds with a color input in the first color space and provides a print output in a second color space. The set of the plurality of nodes are arranged in a vector of a first color perception parameter.

A node in the set of the plurality of nodes that provides a peak amount of the second color perception parameter on the medium is determined. The print output for the end node is replaced with a print output corresponding with the node that provides the peak amount of the second color perception parameter on the medium.

Abstract: A supervisory control and data acquisition (SCADA) unit and technique for managing communications over a network of defined capacity. The unit and techniques include safeguarding the network while allowing for operations to proceed at an oilfield. The safeguards allow for multiple additional and different types of equipment to be added to or removed from the network while being managed by a single SCADA unit. This may be achieved through unique filtering protocols which prevent unidentified and/or unconfirmed equipment and devices from being added to the network merely due to be detected at the oilfield.

Abstract: Color values are measured for a set of color targets printed by a reference printing device on a medium of a reference media type. A different printing device prints a subset of the set of color targets on another medium of this reference media type. The color values of the subset of color targets printed by the different printing device are measured, and the different device calibrated based on the measured color values for both the set that the reference printing device printed and the subset that the different device printed. The different printing device can then also be calibrated for a different media type, based on a transformation of the set of color targets printed by the reference printing device on a medium of the different media type relative to the set of color targets printed by the reference device on the medium of the reference media type.

Abstract: In some examples, with respect to three-dimensional printer color management, three-dimensional printer native space coordinates of a three-dimensional printer may be mapped to three-dimensional printer printing agent space coordinates of the three-dimensional printer. The three-dimensional printer printing agent space coordinates may be mapped to color space coordinates. The color space coordinates may be mapped to two-dimensional printer printing agent space coordinates of a two-dimensional printer. The two-dimensional printer printing agent space coordinates may be mapped to two-dimensional printer native space coordinates of the two-dimensional printer. A color management protocol of the two-dimensional printer may be utilized, based on the mapping of the three-dimensional printer native space coordinates to the two-dimensional printer native space coordinates, for the three-dimensional printer to print a three-dimensional object.
