1. An apparatus comprising:

  • (a) an ultrasonic transducer capable of operating at a plurality of energy settings, wherein each energy setting comprises one or both a frequency or an amplitude of vibrational waves generated by the ultrasonic transducer;

    (b) a waveguide operable to communicate vibrational waves generated from the ultrasonic transducer;

    (c) an end effector coupled to the waveguide;

    (d) a control module;

    (e) a storage device communicatively coupled with the control module, wherein the storage device comprises a plurality of configuration data sets, wherein each configuration data set comprises a respective gesture profile and a corresponding energy setting, wherein the control module is configured to receive a selected configuration data from the storage device;

    (f) an orientation sensor, wherein the control module is configured to receive a first output from the orientation sensor; and

    (g) a force sensor configured to measure a force applied to the end effector, wherein the control module is configured to receive a second output from the force sensor;

    wherein the control module is configured to compare a combination of the first output and the second output to a first gesture profile of the selected configuration data set; and

    wherein the control module is configured to set the energy setting of the ultrasonic transducer to a first corresponding energy setting in response to a correlation between the combination of the first output and the second output to the first gesture profile of the selected configuration data set.
