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: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a capacitive storage circuit is operated at a threshold voltage that is set to provide sufficient power to operate backup functions of a data storage device, and that is further selectively adjusted during a test period to maintain such sufficient power while also providing power to carry out test functions. In other implementations, the threshold voltage is set in response to operating characteristics of one or more of a data storage device to which backup power is to be provided and the capacitive storage circuit itself. The threshold voltage is reduced or otherwise maintained at a low level that is yet sufficient to supply appropriate power (e.g., thus maintaining the capacitive circuit at a voltage level that is about as low as possible, which can enhance operational characteristics of the capacitive circuit).

Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a solid-state memory device is implemented with a primary power source that provides primary power. A secondary power source provides secondary power. A power controller provides the primary power to an operating power circuit. The secondary power is provided by enabling a secondary switch located between the secondary power source and the operating power circuit. A solid-state memory uses power from the operating power circuit as a primary source of power when accessing stored data and retains data in the absence of power being provided by the operating power circuit. A memory controller facilitates access to the stored data. In response to problems with the primary power source, pending writes are completed to the solid-state memory circuit. A timing circuit substantially delays full enablement of the secondary switch.

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.
