摘要:
Described herein are systems and methods of alarm rationalization for an industrial control system. This can comprise building a model of the industrial control system, wherein the model includes components that are monitored or controlled by the industrial control system and alarms associated with the components; training the model by applying one or more machine learning algorithms against a historical database of alarms for the industrial control system; and applying the trained model against the industrial control system for alarm management of the industrial control system.

Methods, devices, and systems for discovery of electronic occurrence-data, including data protected by an information security measure. In an approach, an exemplary system includes data storage operable to store a plurality of instances of occurrence-data, each instance of the occurrence-data having a representative feature, a central computing device operable to communicate with the data storage, and instructions that cause a computing device to perform steps. The steps include receive from an input-selector an input selection corresponding to a target-occurrence having a representative feature, and select a pattern recognition criteria corresponding to the representative feature of the target-occurrence.

A method for determining an operational state of a driver of a vehicle uses an awareness detection arrangement. The awareness detection arrangement includes at least a first and a second source for generating data relating to the behavior of the driver. The method includes receiving, from the first and the second source, data relating to at least one of physiological data of the driver, the operation of the vehicle, and a model of the driver operating the vehicle, comparing the data from the first and the second source with a driver state model defining a plurality of predefined driver states for each of the first and the second source, respectively, determining based on the comparison, for each of the first and the second source, a state probability for each of the plurality of predefined driver states, and weighing the determined driver states for the first and the second source with each other for determining an overall operational state probability for the driver.

A method for detecting a fire flame using fuzzy finite automata is provided. The fire-flame detection method comprises (1) acquiring an image required for the detection of fire-flame, (2) dividing the image into a number of blocks, (3) extracting a fire-flame candidate block using a brightness distortion of a pixel in the block, (4) detecting a fire-flame candidate region from the fire-flame block using a color probability model, and (5) determining whether the fire-flame candidate region corresponds to a fire-flame via fuzzy finite automata. The fire-flame detection method can detect fire-flames in a variety of fire images with relatively high precision, by establishing a probability model using the brightness distortion and wavelet energy in fire-flame regions with continuous and irregular fluctuation patterns and using the upward motion, and applying the model to fuzzy finite automata.

A CBRNE detection system and method for operating same are disclosed. The method provides a relatively increased Probability of Detection and a relatively decreased Probability of False Alarms for a networked system of detectors. In the illustrative embodiment, a central controller of the system is capable of receiving information from individual CBRNE detectors and of determining whether or not to issue an alarm indicating that a CBRNE event has occurred. Data obtained from individual CBRNE detectors is evaluated based on one or more “sensor alert-to-system alarm” processing modes. The various processing modes specify the requirements that must be satisfied before a system-wide “alarm” is issued.
