A generator, ultrasonic device, and method of determining a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency.

Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element. Cartridge assemblies can also include physical features and/or stored data that identify the cartridge. Surgical instruments further can be configured to resolve conflicts when the physical features and/or stored data are not consistent with each other in their identification of the cartridge type.

Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclosed.
