Abstract: Apparatus, such as a portable oxygen concentrator (100) or other device communicating therewith, may be configured, such as with a processor(s), to estimate a remaining capacity of a sieve bed of the concentrator. Such apparatus may be configured to access a parameter of a measured pressure-time characteristic of the sieve bed for a phase of a pressure swing adsorption cycle of the oxygen concentrator. The apparatus may be configured to access function(s) of the parameter of the pressure-time characteristic and operational characteristic(s) of the sieve bed. The apparatus may be configured to estimate the remaining capacity by applying the function(s) to the parameter of the measured pressure-time characteristic. Such an estimate may then serve as a basis for providing notification, such as on a display or by electronic messaging, to inform of remaining life of the sieve bed, or otherwise promote timely replacement of a depleting component.

Abstract: A control system for a heated conduit in a respiratory apparatus includes a power supply configured to provide power to the heated conduit and a heating control circuit configured to control an amount of heat generated in the heated conduit. The control system further includes a sensing circuit configured to indicate the temperature of a sensor positioned in the heated conduit by comparing a reference voltage with a sum of a voltage drop through the sensor and a voltage provided to the sensor by the power supply when the heating control circuit is on. When the heating control circuit is off, the voltage drop through the sensor is solely due to current provided by a current source.
