  • Patent number: 11763241
    Abstract: In an example embodiment, machine learning is utilized to automatically identify pain points of an entity. More particularly, a random forest search algorithm receives inputs from a number of different outside-in data engines. These inputs are segregated in terms of key performance indexes (KPIs), which is then fed to a random forest decision tree. The random forest search algorithm calculates a p-value for each KPI. This p-value may then be used to identify the most relevant KPIs (such as by ranking the KPIs by their respective p-values). Rules are utilized not to identify the pain points themselves, but instead to define sorting preferences (refine the ranking). Based on a combination of the p-values and the evaluation of the rules, the top-N pain points may be identified.

  • Publication number: 20230000547
    Abstract: Systems, devices, and methods for electroporation ablation therapy are disclosed, with the system including a signal generator for generating pre-ablation signals and pulse waveforms for medical ablation therapy that may be coupled to an ablation device including at least one electrode for ablation pulse delivery to tissue. The signal generator may generate and delivery pre-ablation signals to subsets of electrodes of the ablation device and measure currents associated with the delivery to determine whether the currents meet one or more predetermined criteria. The signal generator may also generate and deliver voltage pulses to the ablation device in the form of a pulse waveform after determining that the currents meet the one or more predetermined criteria.

  • Publication number: 20190223937
    Abstract: An electrosurgical system including an electrosurgical unit with amplitude modulated output for ablation surgical devices, whereby the electrosurgical unit generates a signal in either a high mode or low mode, both of which are greater than zero, is disclosed. In at least one embodiment, the electrosurgical unit may be configured such that the power delivered to an electrode assembly of an ablation device in electrical communication with the electrosurgical unit is controlled by varying the duration or the intensity of power delivered during the high and low modes, or both. In another embodiment, the duration of the high mode may remain constant while the duration of the low mode may vary in order to vary the power output from the electrosurgical unit.

  • Patent number: 7398472
    Abstract: Systems and methods for defining at least one visual-display characteristic of at least one user-interface control are disclosed. In accordance with various embodiments of the invention, a dialog template specifies at least one style selector for the at least one user-interface control. A transformation module extracts the at least one style selector from the dialog template. A style sheet defines at least one visual-display-characteristic value that is applicable to the at least one user-interface control and that is associated with the at least one style selector. A style sheet-parsing engine uses the at least one style selector to retrieve the at least one visual-display-characteristic value from the style sheet. And a user-interface-control-drawing module draws the at least one user-interface control in accordance with the at least one visual-display-characteristic value retrieved by the style sheet-parsing engine.
