Abstract: A CO2 monitoring system provides oxygen (O2) to a subject's mask with known characteristics. The CO2 monitoring system receives, from the mask, gas samples including exhaled CO2 diluted by O2. The CO2 monitoring system uses an adaptive noise canceller to cancel the diluting O2 by using the known characteristics of the O2 provided to the mask, the result of which process is restoration of the original concentration level of the CO2 as exhaled by the subject into the mask.

Abstract: A bi-functional filter device for removing liquid from a humid gas flowing through the filter device includes a filter body that includes an axial through-channel that passes lengthwise through the filter's body, through which gas (e.g., humid gas) can flow, and a dehumidifier sleeve that encloses the filter body. The filter body includes a capillary path that may absorb, and thus remove, liquids, for example laterally, radially or spirally (in spiral manner) from the through-channel of the filter body using capillary action, to thus clear the through-channel of the filter body from these liquids. The dehumidifier sleeve may evaporate liquid contained in (and arriving from) the filter body.

Abstract: A diaphragm pump configuration may include an eccentric drive assembly that is configured to be actuated by a motor shaft of a motor including an external magnetic rotor and an inner electrical stator that is contained in the external magnetic rotor. Two bearings may rotatably support the motor's drive shaft such that one bearing is positioned on one side of the eccentric drive assembly, and the other bearing is positioned on the other side of the eccentric drive assembly. The diaphragm pump configuration decreases considerably the workload on the bearing nearest to eccentric drive assembly, and significantly increases the operation time of the diaphragm pump.
