  • Publication number: 20190134330
    Abstract: The present disclosure provides system and methods for pulmonary health using one or more inhalation devices. In one aspect, the air inhalation devices each comprise one or more sensors configured to capture pulmonary health data for a patient. Using this data, air analytics may be generated pertaining to individualized patient health, general health for people living within a particular geographical location, air quality for a particular geographical region, operational parameters of the inhalation devices, and/or the like. The air analytics may be output, for example, for display on a user device, such as a patient user device, a health care provider user device, and/or an administrator user device.

  • Patent number: 4179742
    Abstract: A system for intelligently governing the selection of one of a boiler follow or turbine follow mode of control of a steam turbine power plant is disclosed. Boiler and turbine master controllers are concurrently operative in one of the boiler follow and turbine follow modes for controlling the firing rate of the plant boiler or positioning the steam admission valves of the steam turbine, respectively. Each of the boiler and turbine master controllers are operative to respectively generate a first and second plurality of signals which are representative of plant control status. A selecting means is disposed as an integral part of the plant controls for switching between the turbine follow and boiler follow control modes.

  • Patent number: 4178763
    Abstract: A system which integrates the controls of a steam turbine power plant for minimizing power plant energy losses substantially caused by steam flow valve throttling is disclosed. The steam turbine power plant includes boiler pressure controls for controlling the boiler throttle pressure of a steam producing boiler and turbine-generator controls for positioning a plurality of turbine steam admission values to regulate the steam flow conducted through a steam turbine which governs the electrical energy generated by an electrical generator at a desired power generation level. The turbine-generator controls predetermines a plurality of valve position states to establish a predetermined valve grouping sequential positioning pattern for the steam admission valves to regulate steam flow through the steam turbine across the range of power generation, each predetermined state substantially corresponding to a minimum of valve throttling losses.

  • Patent number: 4064698
    Abstract: A boiler control regulates the input fuel and air to satisfy load demand. Simultaneously, fuel flow is adjusted by fuel flow control to correct for changes in fuel heating value. A computer circuit which generates a heat balance ratio of outlet steam flow and input mass fuel flow as a representation of imbalance between presumed heat input and actual heat output and by inference from the imbalance or change in fuel heating value. The heat balance ratio is multiplied against an actual fuel feedback signal and the ratio corrected signal is applied to the fuel flow control.
