A stow bar for an aircraft fuel nozzle includes a U-shaped body formed of a base part, a first arm extending from one side of the base part, and a second arm extending from an opposite side of the base part. Each of the first arm and the second arm includes a free end located distally of the base part. Each free end includes a male connector for insertion through an aperture in a housing or a flange of the aircraft fuel nozzle. The stow bar is formed of a single, solitary piece of material. The single, solitary formation of the male connectors with the stow bar provide increased strength and durability to the stow bar connection with the fuel nozzle, and is an improvement over known support bar designs having female threaded connectors which receive screws that are prone to break and leave debris within the female connectors.

A diagnostic method and predictor of prognosis from various therapeutic treatments is provided using discriminant analysis statistics. In one form, a patient is identified as having a disease using discriminant analysis when one or more values of a physiological parameter of the patient is closer to that of a previously characterized group of individuals having a disease and the patient is diagnosed as not having the disease, or healthy, if the value of a patient's parameter is closer to that of individuals previously characterized as healthy, or not having the disease. For example, the parameters can be based on the autonomic and/or enteric nervous system. Advantageously, the present method can be readily adapted using conventional linear discriminant analysis statistics to factor more than one parameter between a patient and one or more previously classified groups, to thereby enhance predictability and reliability of the present method. Further, in another form, linear discriminant analysis is used to predict outcomes of various therapeutic treatments of a disease to which a patient is afflicted by comparing the value or values of one or more patient parameter with respective ones in previously characterized individuals having the same affliction which have been treated either successfully or unsuccessfully.

Data about operation of a well for extracting a product from the subterranean reservoir and at least one of a characteristic of a subterranean reservoir or operation of a processing and transport system upstream of a point of sale is received. A corrective action can be automatically initiated on at least one of the well or the processing and transport system in response to a difference between the received data and a specified operational objective. An adjustment to a model of the reservoir, the well, and the processing and transporting system can be automatically initiated in response to the received data.

In certain embodiments, a method for log file time sequence stamping is provided. The method includes connecting to a console port of one or more data sources and receiving data from the data sources. The data may be logged with both an independent time stamp and a sequence indicator. The independent time stamp provides a consistent time stamp of when the data was received at the system and the time sequence indicator represents an order in which the data was received at the system.

A method for modeling a steady-state network in the absence of steady-state historical data. A steady-state neural network can be tied by impressing the dynamics of the system onto the input data during the training operation by first determining the dynamics in a local region of the input space, this providing a set of dynamic training data. This dynamic training data is then utilized to train a dynamic model, gain thereof then set equal to unity such that the dynamic model is now valid over the entire input space. This is a linear model, and the historical data over the entire input space is then processed through this model prior to input to the neural network during training thereof to remove the dynamic component from the data, leaving the steady-state component for the purpose of training. This provides a valid model in the presence of historical data that has a large content of dynamic behavior. A single dynamic model is required for each output variable in a multi-input multi-output steady-state model such that for each output there is a separate dynamic model required for pre-filtering. They are combined in a single network made up of multiple individual steady-state models for each output. The dynamic model can be identified utilizing a weighting factor for the gain to force the dynamic gain of the dynamic model to the steady-state gain by weighting the difference thereof during optimization of the dynamic model. The steady-state model is optimized utilizing gain constraints during the optimization procedure such that the gain of the network is prevented from exceeding the gain constraints.

An industrial control system in accordance with the present invention is provided with a plurality of diverse controlled devices (e.g., fans, pumps, valves, solenoids, relays, etc.) for effecting overall system control. Each device has a unique set of logic control functions and/or command sequences and is connected, through an input/output interface, to a stored-program single board computer that provides device control and monitoring. The computers each include a central processor controlled by a composite or "master" program which is common to all the computers and which includes instruction sequences for all logic control functions and command sequences that exist within the system. A user alterable interconnection device (UAID) permits only those logic control function and/or command sequence portions of the master program that relate to a particular one of the controlled devices to operatively connect with the particular input/output ports associated with that controlled device. As the master program successively loops, only those logic control functions and/or command sequences that relate to the particular controlled device, as determined by the user alterable interconnection device, are operative to address the input-output ports associated with the controlled device and thereby effect device control and monitoring. The invention permits simple and efficient dedication of a plurality of single board computers having only one master program to an equal member of diverse controlled devices without the drawbacks normally associated with dedicated stored-program controllers.

In certain embodiments, a method for monitoring, alerting and remediation of systems is provided. The method provides for receiving data from one or more data sources and logging the data. A first metadata fingerprint is created for a particular data source. The first metadata fingerprint is indicative of a first quantity of data output for the particular data source. A second metadata fingerprint is created for the same data source. The second metadata fingerprint is indicative of a second quantity of data output for the data source. The second metadata fingerprint is created from data received at a different point in time from the first metadata fingerprint. The first metadata fingerprint is compared with the second metadata fingerprint associated with the particular data source. An alert is generated when the comparison indicates that the first metadata fingerprint does not correspond within a specified tolerance to the second metadata fingerprint.

In certain embodiments, a method for monitoring and securing a baseboard management processor is provided. The method includes coupling to a baseboard management controller of a computer system via a console port, maintaining a persistent connection to the baseboard management controller, monitoring data from the console port, determining from the data whether an unauthorized access has occurred, and sending an alert if the unauthorized access has occurred.

A universal mounting plate for replacing a plurality of different door closers with a new door closer, the plate having a substantially flat rectangular body of a material thickness. A plurality of holes are formed through the material thickness and arranged in a plurality of patterns that correspond to the mounting hole patterns of a plurality of different door closers. The mounting plate can be attached to the door through existing mounting holes and the replacement closer attached to the mounting plate. The existing holes in the door are used to mount the plate and the plate is employed to mount the replacement closer, eliminating the need to drill new holes in the door and patching the old holes.
