Peter K. Allen, +1 more
TLDR
In this paper, a first magnetic field can be produced across a tissue region using a first magnetometer, providing a magnetic coupling force between the first magnetic source and a first object, wherein the first object provides a magnetic field or a magnetic susceptibility to obtain the magnetic coupling forces.
Abstract: 
A first magnetic field can be produced across a tissue region using a first magnetic field source, providing a magnetic coupling force between the first magnetic field source and a first object, wherein the first object provides a magnetic field or a magnetic susceptibility to obtain the magnetic coupling force. The magnetic coupling force can be sensed using a force sensor and a resulting sensed force signal can be provided to a controller. The controller can provide an output signal to control the magnetic coupling force using the sensed forced signal to obtain a constant or desired magnetic coupling force.

Determining the state of an ultrasonic electromechanical system according to frequency shift

Cameron R Nott, +7 more
TL;DR: An ultrasonic transducer can be configured to oscillate the ultrasonic blade in response to a drive signal, and a control circuit coupled to the transducers can be used to determine a temperature of the ultrasonic blade, increase an amount of power of the drive signal when the temperature of a blade is less than a first predetermined value, and decrease the amount of energy when the blade is greater than a second predetermined value as discussed by the authors.
