  • Patent number: 11806479
    Abstract: A method of music therapy informed processes provides an effective online process to help a user regulate their mood through appropriate music selection choices. The method offers mood and music assessments to evaluate the user's mood, music preferences, goals, and understanding of the correlation between various moods and music. A mood sequence formula (MSF) is subsequently created to generate stylized and personalized music medicine pill (MMP) playlists. With additional recommendations of music exercise routine/regimen (MER) to the user, the method delivers therapeutic MMP playlists of the music therapy informed process with personalized music to manage physiological and behavioral responses, emotional regulation, performance and emotional intelligence. Using daily tracking and specific measurement data of biometrical and physiological devices, the user can track the progress and thus enable the method to fine tune the MSF and MMP playlists for the best effectiveness of the music therapy informed method.

    Abstract: In some implementations, a method performed by data processing apparatuses includes receiving configuration data for a preconfigured data connector, including connection parameters, time interval parameters, and data transformation parameters. The connection parameters are used to establish a connection to a bulk data source. In response to determining that an amount of time has elapsed that corresponds to the time interval parameters, bulk data is retrieved from the bulk data source for a given time interval, and the retrieved bulk data is transformed in accordance with the data transformation parameters. Based on transforming the retrieved bulk data, a data metric is generated that condenses the retrieved bulk data. A predetermined predicted metric value is received from a prediction data source for the data metric for a time interval that corresponds to the given time interval, and the predicted metric value is stored with the measured metric value.

    Abstract: Robustly stabilizing controller bandwidth for a controlled mechanical system is determined as a function of the system's estimated inertia and dominant system parameters that define constraints on the bandwidth. In one or more embodiments, a bandwidth model is derived that defines a relationship between robustly stabilizing controller bandwidth and system gain over a range of reasonable system uncertainties. Using the model, a suitable controller bandwidth can be determined for a given motion control system given only estimates of the system gain and the dominant parameters(s) that constrain the bandwidth. In an example two-inertia system, the system gain and dominant parameter can comprise system inertia and mechanical coupling stiffness, respectively. Accordingly, estimates of the system inertia and coupling stiffness can be provided to the system, which determines a suitable controller bandwidth for the motion control system characterized by the estimates.

    Abstract: A factory control server stores module configuration data for modules. The modules include processes for producing a final product and have corresponding module requirements. The factory control server analyzes in real-time actual product output data that is generated by a final product tester after a factory produces at least one final product to determine whether the actual product output data meets an expected product output. The factory control server analyzes actual module data in real-time to determine a new module requirement to cause new actual product output data for a subsequent final product to meet the expected product output in response to a determination that the actual product output data does not meet the expected product output. The factory control server notifies a module controller in real-time of the new module requirement. The module controller changes parameters in real-time to manufacture the subsequent final product.

  • Publication number: 20140277606
    Abstract: A process variable transmitter provides an output representing a process variable. The process variable transmitter includes a process variable sensor that provides an analog sensor signal representing a process variable, an analog to digital converter that receives the analog sensor signal from the process variable sensor and converts it to digital sensor signal values, and a compensation processor. The compensation processor calculates, in a first mode, a compensated process variable value at a first slow rate. The compensation processor calculates a compensation factor relating the compensated process variable value to an initial digital sensor signal value. The compensation processor calculates, in a second mode, a process variable estimate as a function of an updated digital sensor signal value and the compensation factor. The process variable estimate is calculated at a second rate faster than the slow rate.

  • Patent number: 8712559
    Abstract: Systems and methods of adaptive control for uncertain nonlinear multi-input multi-output systems in the presence of significant unmatched uncertainty with assured performance are provided. The need for gain-scheduling is eliminated through the use of bandwidth-limited (low-pass) filtering in the control channel, which appropriately attenuates the high frequencies typically appearing in fast adaptation situations and preserves the robustness margins in the presence of fast adaptation.

  • Publication number: 20140081427
    Abstract: The invented controller tuning method relies on the following procedure. To the controlled system with known proportional gain the integral type controller is connected in series. The controller gain kl is increased to get the closed loop system to the stability limit. At this stage the controller ultimate gain ku and the sustained oscillation period period Tosc of the controlled value are assessed. It is assumed that the controlled system dynamics can be approximated by the first order filter with dead time model. The following formulas allow to estimate the first order filter time constant F(1) and the coefficient ?=L/T=(arcctg(?oscT))/(?oscT) where L is the dead time constant of the controlled system model. From the formulas: F(2) the controller model parameters are calculated.

    Abstract: A computer-implemented initial run module processes manifest variable data using computer-defined model specification parameters stored in a database to provide initial estimates of weights that are associated with latent variables. The initial run module employs a unique value-based weighting partial least squares computer-implemented process. A final run module then operates upon the manifest variable data to determine the importance of the predictor values that are then used to control the industrial, manufacturing or commercial process. The final run module implements a unique patient partial least squares regression model utilizing a boosting learning technique.

A criteria comparison matrix representing a relative importance of each decision criterion is created. A criteria importance vector is created based on the criteria comparison matrix, and a supplier comparison matrix corresponding to each decision criterion is also created. The supplier comparison matrix represents a relative ranking of each supplier with respect to the corresponding decision criterion. A supplier criteria ranking vector corresponding to each decision criterion is created based on the supplier comparison matrix that corresponds to the decision criterion. The supplier criteria ranking vectors and the criteria importance vector are combined to create a supplier score matrix associated with the ordering manager agent and indicating a score associated with each supplier.
