  • Publication number: 20190167296
    Abstract: In an energy control device, a processor detects, based on a detection result of an electric characteristic value in relation to an electric energy which is output from an energy output source to an ultrasonic transducer, a gradual decrease start time at which the electric characteristic value starts a gradual decrease after a gradual increase. The processor executes, based on a fact that a time rate of change of the electric characteristic value become greater than a predetermined threshold after the gradual decrease start time, at least one of causing the energy output source to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the time rate of change become greater than the predetermined threshold.

  • Publication number: 20190150974
    Abstract: In an energy control device, a processor detects a gradual decrease start time at which the electric characteristic value in relation to electric energy output to an ultrasonic transducer starts a gradual decrease after a gradual increase. The processor calculates a difference value by subtracting the electric characteristic value from a peak value at gradual decrease start time and calculates an integrated value of the difference value from the gradual decrease start time. The processor executes, based on a fact that the integrated value become greater than a predetermined threshold, at least one of causing to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the integrated value become greater than the predetermined threshold.
