    Abstract: Methods of an apparatus determine a quantity of a body of water in a humidifier such as by indirect measurement. The quantity of water may be determined by measuring one or more properties or characteristics, from which the quantity of water may be inferred. Characteristics of a flow of air, the humidifier, and/or the body of water may be measured. The characteristics may be, for example, pressure, flow rate, noise, vibration, temperature, electrical or mechanical. These may be measured by one or more sensors, which may be located in the humidifier, RPT device, air circuit or the patient interface. The methods described may have advantages, for example in being able to detect the quantity of water without requiring sensors to be present in a disposable component, and in some cases, without introduction of additional sensors.

    Abstract: A CPAP device includes a flow generator comprising a motorized fan with an outlet. The motorized fan is configured to pressurize a supply of gas. The flow generator further comprises a flow generator outlet in communication with and offset from the motorized fan outlet and comprises a connector configured to receive the pressurized supply of gas from the flow generator, the connector being in communication with the flow generator outlet and positioned downstream of the motorized fan outlet. The connector comprises an attaching portion at a first end, the attaching portion configured to be coupled to the flow generator. The connector also comprises a flexible sealing portion at a second end opposite the first end, the flexible sealing portion comprising a bellows-type conforming face seal that is axially and/or laterally flexible. In addition the connector comprises a channel provided between the attaching portion and the flexible sealing portion for delivering the pressurized supply of gas from the first end of the connector to the second end of the connector.
