  • Patent number: 9954692
    Abstract: Systems and methods for controlling devices, including controller and actuators are disclosed. Actuators may be devices where remote control of the device or devices is convenient, such as lights, window shades, fans and similar items. In one method, a user sends a command to a controller and to an actuator. The controller also sends a proxy update to a second controller that is also in communication with the actuator. The proxy controller, also in contact with the actuator, now has knowledge of the state or position of the actuator and is in a better position if the proxy controller is asked to assume control of the actuator. In another method, an actuator or controller may also receive a trigger setup, asking the actuator to tell the controller when an action occurs, but not to take action until receiving a further command from the controller.

  • Patent number: 9248789
    Abstract: A key state detector for a vehicle collects a sequence of battery voltage samples and applies a time-domain to frequency-domain transform (TFT) to the collected samples. The results of the TFT are then applied to an artificial neural network (ANN) to determine if they represent a key-on or key-off state. The ANN is trained based on data collected from the vehicle and is periodically retrained so that the detection of key-on and key-off states conforms to the particular vehicle and tracks the aging of vehicle components.

    Abstract: A method is provided for the measurement of parameters of a gas present in a gas turbine combustion chamber. The method includes tuning a laser to a range containing the absorption lines of species to be analyzed in the gas, and directing the laser light through the combustion chamber and detecting laser light reflected off boundary walls of the combustion chamber. In order to analyze the absorption spectrum measured at high temperatures and pressures, a signature recognition algorithm is applied to the spectrum. The measured absorption spectrum is cross-correlated with a calibration absorption model spectrum for the absorption lines at several temperatures, pressures, and concentrations generated prior to the measurement. Values for pressure, temperature, and concentrations of selected species in the gas are determined simultaneously allowing direct control of the combustion chamber process. An apparatus for carrying out the method is also provided.

    Abstract: A method stores multiple sets of consecutive images of a burner, determines a number of unburned-state images in each set of consecutive images, and determines a threshold number of the unburned-state images in each set of consecutive images for determining whether or not the burner works abnormally. When the burner is turned on, the method sends a first control signal to turn on a camera and receives a set of real-time consecutive images of the burner captured by the camera. The method determines whether or not a number of unburned-state images in the set of real-time consecutive images is less than the threshold number. If the number is equal to or more than the threshold number, the burner works abnormally and a security device connected to the burner is turned off to prevent gas from flowing to the burner.

  • Publication number: 20130245831
    Abstract: A controller determines and adjusts system parameters, including cleanliness levels or sootblower operating settings, that are useful for maintaining the cleanliness of a fossil fuel boiler at an efficient level. Some embodiments use a direct controller to determine cleanliness levels and/or sootblower operating settings. Some embodiments use an indirect controller, with a system model, to determine cleanliness levels and/or sootblower settings. The controller may use a model that is, for example, a neural network, or a mass energy balance, or a genetically programmed model. The controller uses input about the actual performance or state of the boiler for adaptation. The controller may operate in conjunction with a sootblower optimization system that controls the actual settings of the sootblowers. The controller may coordinate cleanliness settings for multiple sootblowers and/or across a plurality of heat zones in the boiler.

  • Patent number: 8521333
    Abstract: An improved method and system for flue gas recirculation (FGR) from the ID Fan located downstream of a scrubber (or other Air Quality Control Equipment including cyclones, baghouses, etc., hereafter “AQC equipment”) back to the scrubber (or other AQC Equipment) inlet to maintain the minimum required flue gas throughput during low-load conditions, thereby eliminating the need for a separate booster fan. A flue gas recirculation duct is connected from downstream of the ID Fan to the inlet of the scrubber (or other AQC Equipment). A variable flow restrictor is placed in the duct downstream of the ID Fan for controlling pressure of the recirculated flue gas. The flow restrictor is controlled in accordance to a function of boiler load or flue gas flow to produce the required backpressure that enables the flue gas to flow through the recirculation duct back to the inlet of the scrubber (or other AQC Equipment) at low loads.

  • Patent number: 8507739
    Abstract: The present invention is a self-powered method for conversion of disposable hydrocarbons into diesel and heating oil fuels and conversion of biomass into biodiesel fuel. The method is operated using a feedstock tank, a preparation tank for first stage warming of the feedstock, a first heat exchanger to separate out water as steam and light ends, a stack to vent steam to the atmosphere, a second heat extension to raise the temperature to the necessary for processing the feedstock in a cracking kettle, a fume incinerator burning the light ends to generate heat for the first and second heat exchangers, a distillation column to process the gases from the cracking kettle, a condenser to convert gas to liquid #2 diesel fuel, a filter and chiller unit and storage tanks to hold the fuels and residuals. The method uses retained heat in the residuals to preheat the feedstock to save energy.

  • Patent number: 8494679
    Abstract: Modern steel production processes require precise knowledge of the current composition and temperature of the liquid metal being processed. In particular during steel production in a converter, high match rates for final carbon content and bath temperature are required. Quantitatively precise blowing of oxygen corresponding to the final target carbon content, and the metal temperature, are decisive factors affecting the economic efficiency of the process and the quality of the steel produced. In order to allow relatively precise process monitoring, various processes and procedures are known, the application thereof being based on measuring exhaust gas composition and on mass flow balances. All models work at an exactness that depends on the precision of the input data, particularly with respect to the weight data of the raw materials and the chemical properties of the metal used.

  • Patent number: 8489241
    Abstract: An exemplary method is disclosed for controlling on-line the steam output of a waste incineration plant that is fed with waste of varying composition. Process or system quantities (u2, u3, xGC, xLL, w0) can be measured repeatedly, at different times during operation of the plant, and a relation with linear parameters (?i) as coefficients of non-linear expressions (?i) of the process quantities can be established by evaluating the measurements. From this relation, an optimal waste feed rate to obtain a desired steam output ({dot over (M)}steam) can be determined and applied to a waste feed actuator of the waste incineration plant.
