With a total of two patents to his name, Johnson's work focuses on enhancing patient care and improving the accuracy of chemical measurements.

Latest Patents

Johnson's latest patents include an "Oxygen and Anesthesia Delivery and Monitoring Device." This innovative device is designed for continuously monitoring oxygen consumption and anesthesia gas uptake in surgical patients. It features servo-controlled replenishment mechanisms that automatically maintain preset levels of oxygen and anesthesia gas for inhalation. The device utilizes a closed, recirculating delivery circuit to administer the appropriate volume of gases to patients. An oxygen sensor monitors decreases in oxygen concentration and triggers restoration to the preset concentration through feedback comparator circuitry. Additionally, any volume changes in the system caused by the uptake of anesthesia gas are monitored by detecting variations in the expansion of a respirator bellows. The desired amount of anesthesia gas is maintained by a potentiometric monitoring device, which produces a voltage proportional to the peak expansion of the bellows.

Another significant patent by Johnson is the "Selective Chemical Sensitive FET Transducers." This invention involves a chemical sensitive field-effect transistor transducer capable of selectively detecting and measuring the chemical properties of substances. The transducer includes a semiconductor substrate with specific doping polarity and diffusion regions that interact with certain substances to modulate an electric field. This modulation provides a measure of the chemical properties, making it useful for various applications, including measuring ion activity and concentrations of gases and enzymes.
