  • System and method of calibration in a powered air purifying respirator
    Patent number: 9192795
    Abstract: A self-calibrating powered air purifying respirator (PAPR). The PAPR comprises an electric motor mechanically coupled to a blower; an air flow sensor, and a controller coupled to the air flow sensor and to the electric motor. The controller is configured to automatically execute a one-time self-calibration by driving the electric motor to a predefined operation point, receiving an indication from the air flow sensor, determining a reference parameter based on the indication from the air flow sensor, and storing the reference parameter, wherein after completion of the one-time self-calibration the controller controls the electric motor based on the stored reference parameter.
    Type: Grant

  • Sensor apparatus and method to regulate air flow in a powered air purifying respirator
    Patent number: 8453646
    Abstract: A probe assembly of a sensor is arranged in an airflow channel. A first probe of the assembly has an inlet. The inlet is at a first point in the airflow channel. A second probe of the assembly has an inlet. The inlet is in fluid communication with the airflow channel. The second probe inlet is closer to a surface defining a perimeter of the channel than is the first probe inlet.
