20090070282 | METHOD AND SYSTEM OF MONITORING PROGNOSTICS - A neural network learns the operating modes of a system being monitored under normal operating conditions. Anomalies can be automatically detected and learned. A control command can be issued or an alert can be issued in response thereto. | 03-12-2009 |
20100114806 | Condition-Based Monitoring System For Machinery And Associated Methods - Real-time condition-based analysis is performed on a machine for providing diagnostic and prognostic outputs indicative of machine status includes a signal processor for receiving signals from sensors adapted for measuring machine performance parameters. The signal processor conditions and shapes at least some of the received signals into an input form for a neural network. A fuzzy adaptive resonance theory neural network receives at least some of the conditioned and shaped signals, and detects and classifies a state of the machine based upon the received conditioned and shaped signals, and upon a predetermined ontology of machine states, diagnostics, and prognostics. The neural network can also determine from the machine state a health status thereof, which can comprise an anomaly, and output a signal representative of the determined health status. A Bayesian intelligence network receives the machine state from the neural network and determines a fault probability at a future time. | 05-06-2010 |
20100138694 | Root-Cause Analysis System And Associated Methods - A method for determining a root cause of a problem in a multiple-element system includes correlating an incoming alarm signal with an element x in a multiple-element system and accessing an implication list comprising a list of all elements upstream of element x. At least one element on the implication list is weighted with data relating to the at least one element. Taking into account the weighting step, a probability is calculated that an element on the implication list comprises a most-probable root cause of the subsequent alarm signal. The identified most-probable root cause of the incoming alarm signal is output. | 06-03-2010 |
20110313955 | REAL-TIME INTELLIGENT VIRTUAL CHARACTERS WITH LEARNING CAPABILITIES - A system, method, and computer-readable instructions for real-time characters with learning capabilities. A plurality of rules are defined in a rules-based system, each of the rules defining a condition that determines a behavior of a virtual agent when the rule is triggered by the condition being satisfied so that upon triggering of multiple rules at the same time, each of the behaviors of the multiple rules whose conditions were satisfied are combined into a resultant behavior for the virtual agent. This resultant behavior is compared with a desired behavior to providing feedback in the form of rewards or punishments to each of the multiple rules based on their corresponding contribution to the resultant behavior as compared to the desired behavior. | 12-22-2011 |

20130268255 | MULTIPLE-ENTITY SCENARIO SIMULATION INCORPORATING HUMAN INTERACTION - Mechanisms for incorporating a human into an automated multiple-entity scenario simulation are disclosed. A Petri-net message processor function (PMPF) receives a first Petri-net message from a source activity node function (ANF). The Petri-net message includes a simulation activity identifier that identifies a first simulation activity. The PMPF routes the first Petri-net message to a first ANF based on the simulation activity identifier. The first ANF receives the first Petri-net message and provides a message to a user based on the first Petri-net message. A response is received from the user. A second Petri-net message is generated based on the response and is communicated to a destination ANF to trigger a second simulation activity by the destination ANF. | 10-10-2013 |
20140168264 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR REAL-TIME ALIGNMENT OF AN AUGMENTED REALITY DEVICE - A system including a structure attachable to a surface in a real world environment, the structure establishing a known location and orientation of the structure, a docking element, as part of the structure, to secure an augmented reality device in a stationary position for alignment of the augmented reality device with the real world environment and with a parallel virtual environment, and a processor operable to perform the alignment by resetting the inertial navigation system of the augmented reality device to the known location when docked in the docking element and aligning the location and orientation of the virtual representation of the augmented reality device in the parallel virtual environment so that the parallel virtual environment in the augmented reality device overlaps the real world environment. A method and computer software produce are also disclosed. | 06-19-2014 |
20140266985 | SYSTEM AND METHOD FOR CHROMATIC ABERRATION CORRECTION FOR AN IMAGE PROJECTION SYSTEM - A system and method for reduction of chromatic aberration for an image projection system utilizes a computer system that processes a parametric equation that defines the physical parameters of a projection lens unit. Based on the parametric equation, the divergence or refractive induced bending of light rays passing through the lens unit is identified. This divergence data is then utilized to generate offset values that are transferred to a control unit of a digital image display unit so as to offset, or otherwise space apart, the position of specific color sub-pixels by an appropriate amount to compensate for the divergence or bending effects of the lens unit. The applied offset causes the color light rays emitted by the color pixels to converge or otherwise join after passing through the lens, thus eliminating, or otherwise minimizing the chromatic aberration associated with the projected image. | 09-18-2014 |
