    Abstract: Systems and methods to reduce the negative impact of wind on an electronic system include use of a first detector that receives a first signal and a second detector that receives a second signal. A voice activity detector (VAD) coupled to the first detector generates a VAD signal when the first signal corresponds to voiced speech. A wind detector coupled to the second detector correlates signals received at the second detector and derives from the correlation wind metrics that characterize wind noise that is acoustic disturbance corresponding to at least one of air flow and air pressure in the second detector. The wind detector controls a configuration of the second detector according to the wind metrics. The wind detector uses the wind metrics to dynamically control mixing of the first signal and the second signal to generate an output signal for transmission.

    Abstract: The invention is a method for real-time estimation of the instantaneous engine speed produced by each cylinder of an internal-combustion engine, from an instantaneous engine speed measurement at the end of the engine transmission system. A physical model, representing in real time the dynamics of the transmission system according to the crankshaft angle and to coefficients of a Fourier series decomposition of the instantaneous speed produced by each cylinder, is constructed. These coefficients are determined in real time from coupling between the model and an adaptive type non-linear estimator. The instantaneous speed produced by each cylinder is then deduced from these coefficients. The mean torque produced by each cylinder can also be deduced therefrom. An application is: engine controls.

    Abstract: The invention relates to a method and a system for controlling the production of a mixture of constituents, especially a mixture with premix dead volumes.By correcting the matrices for calculating the mixture constituents, used in calculating recipes, by introducing limit, order relationship and equality constraints, it is possible to avoid the drifts observed in certain special cases by the implementation of the method and to improve, on the one hand, the diagnostic assistance and the control of the estimation of the properties so as to limit the deviations from the actual quality of the constituents of the mixture and, on the other hand, the speed of manufacture of the mixture and the robustness of the method.The method and the system according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the constituents of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop.

    Abstract: Acoustic Voice Activity Detection (AVAD) methods and systems are described. The AVAD methods and systems, including corresponding algorithms or programs, use microphones to generate virtual directional microphones which have very similar noise responses and very dissimilar speech responses. The ratio of the energies of the virtual microphones is then calculated over a given window size and the ratio can then be used with a variety of methods to generate a VAD signal. The virtual microphones can be constructed using either an adaptive or a fixed filter.
