  • Patent number: 10215814
    Abstract: Systems and methods for cognitive alarm management in a power grid are described. In one embodiment, sensor measurements are transformed to determine the state of a power grid. Given current state information relating to the power grid, various analyses of the alarms may be conducted to produce various rankings of the alarms (e.g., by severity, graph analyses, etc.). In an embodiment, using power flow analysis, an optimal ranking is identified from the rankings in which a causal alarm is prioritized for resolution. Given the resolution of the causal alarm, remaining alarms (either all or a sub-set) may be resolved without further action. Thus, an embodiment provides an appropriate ranking of alarm conditions in a power grid such that the optimal resolution of alarms may be achieved. Other variants and embodiments are broadly contemplated herein.

  • Patent number: 10151215
    Abstract: A control system for a gas turbine engine is disclosed. In embodiments, control system includes a controller and a high speed recorder. The controller obtains sensor values from sensors connected to the gas turbine engine and publishes a map of trigger events. The high speed recorder reads the sensor values from the controller. The high speed recorder checks a map header for a change to the map header on a predetermined map reading interval, sets a flag when the map header has changed, and reads the map during the next loop of the map reading interval. The control system maintains timestamps assigned for the sensor values and to the trigger events on the same temporal axis.

  • Patent number: 10145877
    Abstract: In an exemplary embodiment of the disclosure, a signal analyzer includes at least one noise reduction system in the form of an adaptive noise reduction system. The adaptive noise reduction system executes an adaptive noise floor extension (NFE) procedure that includes determining a predicted standard deviation of a response by the signal analyzer to intrinsic noise in the signal analyzer when various signal processing parameters desired by a user are applied to an input signal. The predicted standard deviation is then used in the signal analyzer to select and apply various noise subtraction values upon the input signal before displaying of a signal spectrum of the input signal upon a display of the signal analyzer. The adaptive NFE procedure is directed at reducing or eliminating various ambiguities and/or errors in the displayed signal spectrum.

  • Patent number: 10101402
    Abstract: A method for estimating battery power capability in a torque-generating system having a battery pack with battery cells includes calculating a voltage spread as a difference between an average and minimum cell voltage of the battery pack. The method also includes increasing a calibrated voltage control limit by an offset that is based on a magnitude of the voltage spread, doing so when the minimum cell voltage is less than the control limit, and recording the offset in a memory location referenced by pack operating conditions. Further, the power capability is estimated using the recorded offset when the battery pack operates under conditions that are the same as the operating conditions, and then executing a control action of the system using the estimated power capability. A torque-generating system includes the battery pack, an electric machine, and a controller programmed to execute the above-described method.

  • Patent number: 10094654
    Abstract: An integrated sensing device with a suite of sensors assists construction machine operators in finding the correct level to dig a ditch/trench. The sensing device includes a gravity sensor to determine angles, a laser distance meter (LDM), and a laser receiver for detecting a known jobsite elevation. The sensing device is mounted to the dipper stick of an excavator; the gravity sensor detects the angle of the stick, and the laser receiver detects a laser plane of light that represents a known jobsite elevation. The LDM is aimed at another member of the machine that moves in a predetermined path as the bucket is rotated, and the distance between the LDM and the target member is used to calculate the vertical elevation of the working tool edge. A display graphically shows the operator the proper dig depth and the present position of the working tool edge.

  • Patent number: 10088413
    Abstract: Methods and systems for calibrating system parameter values of a target inspection system are presented. Spectral Error Based Calibration (SEBC) increases consistency among inspection systems by minimizing differences in the spectral error among different inspection systems for a given specimen or set of specimens. The system parameter values are determined such that differences between a spectral error associated with a measurement of a specimen by the target inspection system and a spectral error associated with a measurement of the same specimen by a reference inspection system are minimized. In some examples, system parameter values are calibrated without modifying specimen parameters. Small inaccuracies in specimen parameter values have little effect on the calibration because the target system and the reference system both measure the same specimen or set of specimens. By performing SEBC over a set of specimens, the resulting calibration is robust to a wide range of specimens under test.
