摘要:
Method, system and computer program product are provided for estimating a circadian phase of a subject by: obtaining a sensed biological signal for the subject; and using, by one or more processors, adaptive frequency tracking to adaptively estimate the circadian phase of the subject from the sensed biological signal. Circadian phase estimation may be accelerated by providing a feedback loop for the adaptive frequency tracking, which utilizes, in part, a circadian phase model in automatically ascertaining a phase correction for the adaptive frequency tracking. The circadian phase estimation may be used in automatically constructing a light-based circadian rhythm model for the subject using a linear parameter-varying (LPV) formulation, and once constructed, the circadian rhythm model for the subject may be used to provide light-based circadian rhythm regulation.

The present invention disclosed a method constructing an intelligent system processing uncertain causal relationship information. It can express, monitor and analyze the causal logic relationship among the different variables in complex systems directly, implicitly or in both way of them under the circumstance of unsure, dynamic, having a logic loop, lacking of statistical data, unclear evidence, discrete variables state or continuous mixture of variables state, incomplete knowledge, multi-resource of knowledge. It gave effective bases to the problems in the domain of producing, monitoring, detecting, diagnosing, forecasting et al.

A fluid flow measuring and control device for measuring a flow rate based on a pressure drop created by a restrictive flow element (15). The device includes a proportional flow valve (10) having a fluid inlet and a fluid outlet and an actuator (17) for modulating the proportional flow valve (10). The restrictive flow element (15) includes a fluid inlet and a fluid outlet in communication with the proportional flow valve (10) and creates a pressure drop between the restrictive flow element fluid inlet and outlet. The device also includes means (24, 25) for measuring the pressure drop, means (16) for calculating the flow rate based on the pressure drop, and control means (not shown) that communicates with the pressure drop measuring means (24, 25) and the actuator (17) for controlling the flow of fluid through a proportional flow valve (10) in response to the measured pressure drop.

A method for remote animal surveillance and distress monitoring includes detecting biometric and behavioral parameters of the animal, identifying novel events based on comparison of detected parameters to predefined parameter values and qualifications; determining whether a composite parameter value exceeds a predefined composite threshold value indicative of possible distress in the animal; and notifying remote caretakers of possible distress in the animal based on the composite value exceeding the predefined composite threshold value.

A method for assessing the quality of ITS related traffic data is disclosed that comprises determining samples of traffic data collected for a particular type of traffic measure, for a particular sample of traffic data under analysis, defining a set of quality indicators l x that assess said sample with respect to different aspects, for each of said quality indicators l x , calculating a quality indicator value by evaluating the consistency and/or deviation of said sample with respect to a spatial or temporal neighbor sample by means of applying different analyses tools for each of said quality indicators l x . Furthermore, a corresponding system for assessing the quality of ITS related traffic data is described.

L'invention porte sur un ystème de traitement de données (MODFD) pour la surveillance d'un système complexe, le système de traitement étant configuré pour recevoir des informations d'état (MSGPB, MSGCAP) et fusionner au moins lesdites informations d'état en une information de panne (MSGPC), au moins une desdites informations d'état étant associée à un indicateur de confiance (NC2), et l'information de panne étant également associée à un indicateur de confiance (NC3), caractérisé en ce qu'une fusion est effectuée en mettant en œuvre une technique de logique floue pour produire l'information de panne en tenant compte des indicateurs de confiance (NC2) respectifs des informations d'état et produire l'indicateur de confiance (NC3) associé à l'information de panne.
摘要:
A fuzzy logic controller for a distributed control system that monitors a large electrical machine in order to detect and identify faults. Variables to be monitored by the fuzzy logic controller include oil pressure, oil temperature, and other critical variables that are used under classical logic to trip the electrical machine offline. After the input and output membership functions are identified, and a rule set is defined, the fuzzy logic controller fuzzifies the monitored variables to the input membership functions, determines an antecedent truth value, and implicates the antecedent truth value onto the output membership function, establishing a fuzzy output set. Where multiple output fuzzy sets are to be combined, they are amalgamated. The output fuzzy set or amalgamated combined output fuzzy set is then converted to a crisp value.
摘要:
A method of behavioral training is provided, wherein psychophysical reactions of an exemplary specimen are transformed into computable statements, associated with a perception process, using fuzzy logic. The computable statements are incorporated into an expert system, and the expert system of the perception process combined with a neural network corresponding to a perception model, so as to form a behavioral system. A stimuli is introduced to the behavioral system and an exemplary response elicited therefrom. An untrained specimen, also introduced to the stimuli, is induced to mimic the exemplary response so as to train the untrained specimen to display the psychophysical reactions of the exemplary specimen. A rehabilitation method, as well as associated methods, systems, and computer program products, are also provided.
摘要:
Various methods, devices, systems, and computer programs are disclosed relating to the use of models to represent systems and processes (such as manufacturing and production plants). For example, a method (200) may include generating a first model and a second model using operating data associated with a system or process (100). The method may also include using the first and second models to predict one or more events associated with the system or process (100). The one or more events are predicted by generating one or more initial event predictions using the first model and adjusting the one or more initial event predictions using the second model. The first model may represent a Principal Component Analysis (PCA) model, and the second model may represent a Fuzzy Logic model.
