Abstract: A control method and a wind turbine for adaptively adjusting the operation of the wind turbine to maintain maximum power production during degraded conditions. The control system has an estimator module that determines a scaling factor based on the current set of control signals and at least the current set of measurement of the operating parameters. The scaling factor is transmitted to a control module which scales at least one aerodynamic property of the rotor based on this scaling factor. The control module further determines the ideal settings for the control signals based on the scaled aerodynamic properties. The present control method scales the aerodynamic properties to provide a better representation of the actual degraded aerodynamic properties.

Abstract: A metabolism monitoring system, data analyzer, and method is disclosed for processing data to very quickly estimate metabolic parameters. The analyzer of the invention uses a dynamic observer state estimator to estimate the parameters and tracks their values as they change with alterations in the patient metabolism or testing conditions. The state estimator does not use the conventional steady state solutions. The observer predicts the patient consumption of oxygen and exhalation of carbon dioxide at a subsequent point in time, corrects these values using measurements of air flow rate and chamber levels of oxygen and carbon dioxide taken at that subsequent time, and repeats for the next time. The corrected values are used for estimation of the metabolic parameters.

Abstract: A method for wind turbine tower load control includes controlling the pitch of the rotor blades in a conventional manner by a collective command component. An estimator estimates the tower resonant acceleration and the thrice-per-revolution blade imbalance acceleration. Combining logic, connected to the estimated resonant acceleration and to the estimated thrice-per-revolution (3P) acceleration provides a combined pitch modulation to damp the tower resonant motion and the thrice-per-revolution motion using collective modulation. The pitch modulation is combined with the collective command component to drive the pitch actuators.

Abstract: A turbine control system for a variable speed electrical generator in a wind turbine mounted atop a support tower. The wind turbine converts wind energy into a driving torque applied to the generator. The control system includes a turbine support tower position sensor and may also include other tower acceleration and velocity sensors. A wind flow estimator uses the measured motion, generator rotation rate and blade pitch angle to predict wind flow over the swept area of the turbine's rotor, and the tower motion. The predicted wind flow and motion is used in the turbine control system to properly adjust its operating point, to tune the controller, to control the rotor rotation rate, and to damp tower oscillations.

Abstract: Energy for in-tire use is generated from the load induced reciprocating deflection of the tire inner walls above the tire-to-road contact patch adjacent to the shoulder of the tire. This energy is used to power in-tire monitoring electronics. For pulsatile energy generation with capacitive capture, the capacitor is optimally selected in real-time as a function of pulse width to maximize energy capture, or as a function of the pulse-captured energy. The resulting energy pulses are also used to measure the time duration of the contact patch from which the contact patch length is determined thus providing real-time tire geometry and, with tire pressure, real time tire load and, with temperature, tire air molar content. The loads on all tires provide real time vehicle mass and mass distribution. For electrical energy generation, magnet-coil, piezo-electric, and other power conversions are applicable. For non-electric energy generation, fluid bellows, rotary pump, and other power conversions are applicable.

Abstract: Noninvasive in vivo real time analyte measurement uses a multitude of sensors binding reversibly to the analyte whereby the response of the sensors to a noninvasive stimulus is altered by their bound versus unbound state. The stimulus and responses are electromagnetic, magnetic or any other suitable forms. The sensors are bound to a blood component providing transport through the body fluids and sensor elimination. A sensor is constructed from proteins or as a nanodevice. A noninvasive device generates the stimulus, senses the responses, determines the measurement, and controls a medication infusion pump. A non-contact device is used for population screening, and one form of such a device is a nuclear magnetic resonance imager. Measurement in fluids other than blood uses a blood component flowing out of blood and into the desired fluid.
