摘要: An adaptive calibration method in a brain-computer interface is disclosed. The method is used to reliably associate a neural signal to an object whose attendance by a user elicited that neural signal. A visual stimulus overlaying one or more objects is provided, at least a portion of the visual stimulus having a characteristic modulation. The brain computer interface measures neural response to objects viewed by a user. The neural response to the visual stimulus is correlated to the modulation, the correlation being stronger when attention is concentrated upon the visual stimulus. Weights are applied to the resulting model of neural responses for the user based on the determined correlations. Both neural signal model weighting and displayed object display modulation are adapted so as to improve the certainty of the association of neural signals with the objects that evoked those signals.

摘要: A device for diagnosing a fault in a bearing of a motor is provided. If the device operates in a fault diagnosis mode, a current signal acquisition unit acquires a real-time current signal of the motor, a residual signal acquisition unit extracts harmonic signals from the real-time current signal of the motor acquired by the current signal acquisition unit and remove a fundamental signal and a harmonic signal from the real-time current signal of the motor to acquire a residual signal, a fault feature extraction unit analyzes the residual signal in both time domain and frequency domain to extract a fault feature index of the bearing, and a fault diagnosis model unit performs, by using a bearing fault diagnosis model obtained through training, pattern recognition on the fault feature index to diagnose a fault state of the bearing.

摘要: The present invention relates to a technique for identifying geological and drilling patterns by analyzing data from drilling parameters, using periodic orthogonal functions applied to such data. The use of averages to convert time data to depth data acts as a low-pass filter, attenuating the textural information from the torque data. Therefore, with the use of simple statistical filters combined with the use of multidimensional data visualization methods, it is possible to discretize drilling and geological patterns in the depth data acquired, aiding in the characterization of the top of the pre-salt carbonate reservoir, minimizing the geological and engineering risk in these operations. It is noted that in some situations of well kill, it is common not to have perceptible contrasts when analyzing the drilling parameters in the transition between the basal anhydrite and the carbonates, with the use of techniques such as PCA (Principal Components Analysis) being necessary in order to increase the method's power of discrimination. The technique disclosed minimizes the exploratory risks in pre-salt kill situations, as it allows precise characterization of the top of the carbonate reservoir.
