First Claim
Patent Images
1. An airflow apparatus, comprising:
- an impeller to generate an airflow at a positive applied pressure to a nasal attachment; and
a controller coupled to the impeller, the controller to receive operational information from the impeller to determine a value of the positive applied pressure, the controller to apply an adjustment policy to the impeller in response to the operational information.

Abstract
Methods, apparatus, and systems for an airflow system, wherein the positive applied pressure is maintained at an approximately constant level over a variety of conditions. In one embodiment, a laminar flow is maintained by a foam housing and configuration. The use low air volume is enabled by using a closed system, wherein feedback information from the system is used to control the speed of an impeller. In one embodiment, moisture recirculation and recycling is applied to extract moisture from exhalation and inject the moisture back into the inhalation portion of the breathing cycle.

9. A method for controlling airflow generation, comprising:
-
receiving operational information corresponding to a positive applied pressure of an airflow generated by an impeller; determining the positive applied pressure based on the operational information; comparing the positive applied pressure to a pressure setpoint; when the positive applied pressure does not equal the pressure setpoint applying an adjustment policy to the airflow generation.
