POWER FAILURE MANAGEMENT FOR RESPIRATORY SYSTEM HEATER UNIT
First Claim
1. A method of power failure management for a heater unit including a heater configured to impart heat to a portion of a respiratory system, the heater adapted to be selectively energized from a source of electrical supply, the method comprising:
- monitoring the source of electrical supply for a disruption;
in response to detection of a disruption of the source of electrical supply, sounding an audible alarm.

Abstract
A heater unit includes power failure management to detect disruptions in the electrical power supply, such as the AC supply, for the unit. The heater unit emits an audible alarm in response to detection of such a disruption, and may shut down the heater(s) and visuals display(s). The heater unit advantageously includes a power storage device, such as a super-capacitor, to temporarily power the electronic circuitry of the heater unit. Operating parameters, such as of a processor of the electronic circuitry, may be stored in a non-volatile memory response to the disruption, and recalled if the disruption terminates before the level of power has gotten too low to sustain reliable operation of the processor.

15. A heater unit comprising:
-
a heater configured to impart heat to a portion of a respiratory system; a power supply coupled to a source of electrical supply and adapted to output a regulated DC supply; electronic circuitry adapted to be energized from the regulated DC supply, the heater responsive to the electronic circuitry whereby to be selectively energized from the source of electrical supply, the electronic circuitry being responsive to disruption of the source of electrical supply to output a power disruption signal; and an alarm responsive to the power disruption signal to generate an audible alarm whereby to provide an alert indicative of the disruption. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
