  • Patent number: 11810596
    Abstract: A method for training a speech-emotion recognition classifier under a continuously updatable and re-trainable ASER machine learning model. The quantified training data is generated by first processing the utterances of a human speech source and the associated texts in an emotion evaluation and rating process with normalization; then, extracting the features of the utterance; quantifying the feature attributes of the extracted features by labelling, tagging, and weighting the feature attributes, with their values assigned under measurable scales. The quantified training data comprises the normalized results of the emotion evaluation and rating process, the extracted features, the quantified emotional feature attributes, and the hash values of the quantified emotional feature attributes.

  • Patent number: 10809217
    Abstract: A system (1) for detecting and locating corrosion on the outer surface of a metal body (2). The system includes an extended electromagnetic waveguide (6) arranged adjacent to the outer surface of the metal body. The electromagnetic waveguide includes a sacrificial component that experiences substantially the same environment as the outer surface of the metal body. The system also includes a waveform generator (10) arranged to be connected to the waveguide and to inject an electromagnetic waveform into the waveguide. The system also includes a waveform analyser (12) connected to the waveguide. The waveform analyser is arranged to receive a reflected portion of the injected electromagnetic waveform from the waveguide. The reflected portion of the injected electromagnetic waveform is used by the waveform analyser to determine the location of corrosion of the sacrificial component of the waveguide.

  • Patent number: 8489244
    Abstract: A method of controlling the flow of a multiphase fluid through a pipeline that includes a riser pipe with a choke valve comprises receiving multiple signals dependent on fluid flow properties from a plurality of sensors in the topside area of the riser pipe, analysing the signals to establish a vector of measurement weights, the product of the vector of measurement weights and a corresponding vector of the signal values of a given time being dependent on the severity of a slug flow forming in the system. Further signals dependent on fluid flow properties are received from the plurality of sensors in the topside area of the riser pipe. A set position for the choke valve is then determined from the product of the vector of measurement weights and further values of signals to restrict characteristics of the flow in the topside from moving towards a severely slugging flow regime.

  • Publication number: 20130096831
    Abstract: A system, method and computer program product for managing sensors. One example of embodiment includes a data reader to receive sensor measurements from sensors. A user value collector receives user values from users representing a user's measurement of an abstract concept. A data store saves the sensor measurements and the user values in computer readable memory. The system further includes a virtual sensor generator. The virtual sensor generator determines a mapping function based on the stored sensor measurements and user values. Furthermore, given a new set of sensor measurements from the sensors, the virtual sensor generator employs the mapping function to generate a new virtual sensor value.

  • Patent number: 8275642
    Abstract: A method and system of predicting a maintenance schedule and estimating a cost for warranty service of systems, for example, hardware systems, is provided. The method and system in one aspect may collect component usage data and obtain component reliability data for each of the plurality of components. A component life distribution module (CLDM) may be constructed based on the real time component usage data and the component reliability data, and from CLDM a mean time to fail data may be obtained. A system life distribution model (SLDM) may be selected and the mean time to fail data input into the SLDM to obtain an operating environment index that represents the effect of environment conditions on the lifetime and reliability. A maintenance schedule may be predicted and an adjusted cost of warranty service may be calculated based on the operating environment index for each of the plurality of components.

  • Patent number: 7958552
    Abstract: A system and method are provided to establish trust between a user and a policy system that generates recommended actions in accordance with specified policies. Trust is introduced into the policy-based system by assigning a value to each execution of each policy with respect to the policy-based system, called the instantaneous trust index. The instantaneous trust indices for each one of the policies, for the each execution of a given policy or for both are combined into the overall trust index for a given policy or for a given policy-based system. The recommended actions are processed in accordance with the level or trust associated with a given policy as expressed by the trust indices. Manual user input is provided to monitor or change the recommended actions. In addition, reinforcement learning algorithms are used to further enhance the level of trust between the user and the policy-based system.

  • Patent number: 7857059
    Abstract: A system for mitigating slugging in the conveyance of hydrocarbons in a flowline includes a first portion of flowline that extends substantially longitudinally along a declining surface. The first flowline portion carries multiphase hydrocarbons. A second portion of flowline extends upward from adjacent the first portion of flowline, and is in fluid communication with the first portion of flowline. A slug-mitigating region is between the first and second portions of flowline so slug-mitigating assembly receives the hydrocarbons from the first portion of flowline and conveys the hydrocarbons to the second portion of flowline. The slug-mitigating region has consecutively joined tubular segments that are each arcuate along a predetermined arcuate angle, with substantially uniform cross-sections. The first portion of flowline can be a subsea flowline extending along a sea floor, and the second portion of flowline can be a riser.

  • Patent number: 7487494
    Abstract: The present invention is directed to systems and methods that treat the monitoring of a software application as a separate and independent concern from the software application itself. The present invention utilizes aspect oriented programming to intercept, analyze, decompose the application states of a software application and then to link appropriate non-invasive constructs into the software application code to provide application state information to an autonomic manager through a plurality of sensors. The autonomic manager analyzes the application state information for compliance pre-defined parameters, and takes appropriate corrective action including modifying the software application states using a plurality of effectors. The sensors and effectors are linked as non-invasive constructs to the software application, and in aspect oriented programming constitute aspects.

  • Patent number: 7475152
    Abstract: The present invention utilizes agents embedded in content delivered to clients across a network to provide client-side security for the data delivered to a client. These embedded agents provide application-specific protection for the delivered content in which they are embedded and eliminate the need for using plug-ins for security functions. Different agents, e.g. programs such as Java applets, are configured having a variety of different client or application specific protection mechanisms, and the agents are dynamically configured, e.g. selected, in accordance with the application, the client to be protected or other environment criteria. Once the agent has been appropriately configured, the agent is embedded in the content, and the content is delivered to the client. Once delivered, the embedded agent is uploaded to the client and executed, providing the configured security protection at the client side for the content in which it was embedded.
