  • Publication number: 20190184532
    Abstract: When coupling tubular parts by fitting, the seal interposed between them may roll on itself, be pinched or damaged. Now, a twisted or damaged seal no longer correctly ensures the seal-tightness and it is very difficult to detect this. The present application discloses a tool for installing a seal between two tubular parts, one male and one female, including a compression ring to encircle the male part and exert a compression on the seal before producing the join. The tool also includes a tongue that can be positioned at a chamfered surface of the female tubular part. The tongue makes it possible to offer the pre-compressed seal with the dimensions of the female part a continuous travel making it possible to prevent any twisting or other effect compromising the seal-tightness.

  • Patent number: 10309168
    Abstract: A method for monitoring a makeup state of a threaded connection including a male threaded tubular element and a female threaded tubular element. In the method, during makeup of the male threaded element into the female threaded element, a variation with time of a dimensional characteristic of at least one of the elements is measured in a pre-defined direction. Next, the variation with time of the characteristic is analyzed to determine a makeup state for the threaded connection.

  • Patent number: 8838278
    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.

  • Patent number: 8827543
    Abstract: The invention relates to a method and a device for controlling the production of a mixture of components, especially a mixture with premix dead volumes. The method and the device according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the components of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop. Thus, the desired properties of the mixture are guaranteed despite large uncertainties in the properties of the components on the one hand, and partial knowledge of the mixing process on the other.

  • Publication number: 20140126744
    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.

  • Publication number: 20140099722
    Abstract: A method for controlling a flow-rate of fluid flowing in a microfluidic network comprising a microchannel and a plurality of inlet/outlet interface ports is disclosed. The method includes: successively applying a plurality of pressures on at least one inlet/outlet interface port, measuring a time series of flow-rate values of the fluid generated in response to the plurality of applied pressures, estimating parameters of a model of the microfluidic network response to input pressure values based on the applied pressure values and the measured time series of output flow-rate values, computing a target pressure value at each of the inlet/outlet interface ports corresponding to a predetermined flow-rate value at the flow-rate measuring point, wherein the predetermined flow-rate value corresponds to an output value of the model of the microfluidic network response to the target pressure value, and applying the computed target pressure value on the at least one inlet/outlet interface port.

  • Patent number: 8503686
    Abstract: A voice activity detector (VAD) combines the use of an acoustic VAD and a vibration sensor VAD as appropriate to the conditions a host device is operated. The VAD includes a first detector receiving a first signal and a second detector receiving a second signal. The VAD includes a first VAD component coupled to the first and second detectors. The first VAD component determines that the first signal corresponds to voiced speech when energy resulting from at least one operation on the first signal exceeds a first threshold. The VAD includes a second VAD component coupled to the second detector. The second VAD component determines that the second signal corresponds to voiced speech when a ratio of a second parameter corresponding to the second signal and a first parameter corresponding to the first signal exceeds a second threshold.

  • Patent number: 8488803
    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.

  • Patent number: 8418442
    Abstract: Method of controlling the active regeneration of a particulate filter through dynamic control of the temperature at the outlet of an oxidation catalyst. A control law is defined for a hydrocarbon flow rate at the oxidation catalyst inlet, by means of the ratio between a temperature demand and a gain. The gain can be corrected so as to take account of the transient phenomena that occur in the oxidation catalyst during a gas flow rate variation. The temperature demand can comprise a precompensation term to compensate for the effects of a temperature variation at the oxidation catalyst inlet. The temperature demand can comprise a feedback term calculated by a controller whose parameters are automatically calculated by means of a physical model of the catalyst, during operating conditions variations. Any combination of these terms allows to define a suitable control law.

  • Patent number: 8374097
    Abstract: A user equipment (UE) operating in a wireless network receives a sequence of speech frames on a speech channel. The UE demodulates at least a portion of a speech frame of the sequence of received speech frames to produce a metric value. The UE discontinues processing of the speech frame and enters a low power discontinuous reception (DRX) mode if the metric value indicates absence of valid speech data, and ignores and does not demodulate at least the next remaining bursts of the speech frame after entering DRX mode.
