Abstract: A method according to one embodiment includes receiving real-time sensor data from a plurality of pump sensors, wherein each pump sensor of the plurality of pump sensors is configured to generate sensor data associated with at least one characteristic of the pump's operation, comparing the real-time sensor data to at least one threshold value, determining fault information in response to determining the real-time sensor data is outside of one or more of the at least one threshold value, determining a real-time operating point of the pump on a pump performance curve associated with the pump based on the real-time sensor data, displaying, on a graphical user interface of an administrative device, the real-time operating point of the pump on the pump performance curve, and displaying, on the graphical user interface of the administrative device, the fault information in real time.

Abstract: An electrodynamic printing system with at least one conductive stylus electrode against the back side of a sheet to be written upon and a store of solid conductive writing material, preferably in a roller electrode form, disposed on the opposite side of the sheet. A circuit is provided to apply current pulses between the electrodes causing current flow therebetween through the sheet sufficient to erode writing material from the front electrode and cause it to become implanted on the sheet, for forming a writing pattern. A linear array of stylii aligned with the roller provides a line printer apparatus.
