  • Low cost CPAP flow generator and humidifier assembly
    Patent number: 8739780
    Abstract: A CPAP device wherein humidification detection and/or control is performed by a microprocessor of the CPAP device without requiring a separate humidification control chip. The microprocessor may also control the flow generator motor and the flow generator display. Further, the microprocessor may include code to prevent ‘brown-out’, and/or to detect the availability (connection and/or operability) of the humidifier. Humidifier detection may be carried out using power consumption or temperature sensor signal analysis, e.g., facilitated by use of a pull-up resistor.
