Title: Innovations by Joshua H Johnson
Introduction
Joshua H Johnson is a prominent inventor based in Arvada, Colorado. He has made significant contributions to the field of surgical technology, holding a total of 15 patents. His work focuses on integrating advanced technologies, such as machine learning, into surgical instruments and systems.
Latest Patents
One of Johnson's latest patents is for surgical instruments and systems that incorporate machine learning-based tissue identification. This innovative surgical system features an end effector assembly with first and second jaw members, a generator, and machine learning applications. The jaw members can move from a spaced-apart position to an approximated position to grasp tissue. They are designed to conduct energy through the tissue grasped between them. The generator supplies energy to the jaw members and includes a main controller and sensor circuitry to sense impedance and power. The machine learning applications determine the type of tissue based on the sensed impedance and power.
Another notable patent involves dead-time optimization of resonant inverters based on the input voltage of a tank. This electrosurgical generator includes a resonant inverter with an H-bridge and a tank. A sensor array measures properties of the tank, while a pulse width modulation (PWM) controller outputs timing signals to the H-bridge. The PWM controller optimizes the dead-time between the signals based on the properties measured by the sensor array.
