An improved incubator and control apparatus include separate temperature and humidity control loops wherein a commanded temperature and a commanded relative humidity (RH) value are commanded to the control apparatus via a user interface. The control apparatus employs a humidifier rate saturation controller which acts responsive to both a humidity control signal and a current temperature to regulate the addition of humidity to the air within the incubator assembly to avoid a transient humidity from exceeding a predetermined value and thereby avoiding the generation of condensation within the incubator.

Incubator assembly and associated control apparatus that controls humidity rate

An improved incubator () and control apparatus () include separate temperature and humidity control loops () wherein a commanded temperature () and a commanded relative humidity (RH) value () are commanded to the control apparatus via a user interface (). The humidity control loop () employs specific humidity (SH) in its control operations. The use of SH rather than RH decouples humidity from temperature and thus simplifies control of both.

An infant warming assembly includes a heater assembly having a heater surface temperature sensor, a skin temperature sensor, and a user interface to input a commanded skin temperature value. The skin temperature sensor and the commanded skin temperature value are used in controlling a temperature component of a control loop. The heater surface temperature sensor is used in controlling a power component of the control loop that powers the heater based at least in part upon the heater surface temperature sensor and a control signal from the temperature component.
