Abstract: A continuous positive airway pressure system comprises an inspiratory portion, an expiratory portion, and a controller. The inspiratory portion is coupled to a patient interface to provide an airflow with positive pressure to a patient. The inspiratory portion includes a first sensor to measure a pressure and/or a flow rate of the airflow at the inspiratory portion. The expiratory portion is coupled to the patient interface to receive air exhaled from the patient. The expiratory portion includes a second sensor for measuring a pressure and/or a flow rate of the air exhaled at the expiratory portion. The controller (i) determines a pressure at the patient interface based on the measured pressures and/or the flow rates of the airflow at the inspiratory portion and the air exhaled at the expiratory portion and (ii) modifies the airflow provided by the inspiratory portion based on the determined pressure.

Abstract: Provided are mechanisms and processes for an adjustable mobility assistive device. In various examples, the adjustable mobility assistive device includes a first frame including a slotted rail S1 and a slotted rail S3 coupled by post P1 and post P3. Both slotted rail S1 and slotted rail S3 may be quarter circular in shape. The adjustable mobility assistive device also includes a second frame including a slotted rail S2 and a slotted rail S4 coupled by post P2 and post P4. Both slotted rail S2 and slotted rail S4 may be quarter circular in shape. Post P2 is slidably connected to slotted rail S1 and slotted rail S3, and post P3 is slidably connected to slotted rail S2 and slotted rail S4. Post P2 is adjacent to post P3 when in a fully extended position and post P1 is adjacent to post P2 and post P3 is adjacent to post P4 in a retracted position.
