A fluid flow control system has a heating device for heating a fluid and a first flow path for providing the heated fluid from the heating device to a use region. A heat exchanger has a supply path that received fluid from a fluid supply, and an outlet path that receives fluid from the use region, whereby the fluid in the supply path is pre-heated by the fluid in the outlet path. A second flow path provides pre-heated fluid from the supply path of the heat exchanger to the heating device. Modulating devices control fluid flow through the outlet path along the supply path. A flow control device controls the modulating devices such that the fluid flow rates in the fluid supply path and outlet path of the heat exchanger are balanced, so as to be substantially the same.

A system and method for operating a ventilator to compensate for external gas flow reaching a patient from an external device, such as a nebulizer. A control unit of the ventilator monitors the gas flow rate from the ventilator and compares the gas flow rate from the ventilator to an expired gas flow rate from the patient. The difference between the inspired flow rate and the expired flow rate is due to the external device. The control unit modifies the operation of the ventilator to compensate for the external gas flow rate such that the flow of gas reaching the patient is maintained at a desired level.

A capillaritron ion beam sputtering system and a thin film production method are disclosed. By utilizing reactive capillaritron ion beam sputtering deposition, argon and oxygen are passed through a capillaritron ion source simultaneously. Argon is being ionized and accelerated by a voltage to bombard a zinc target and create zinc atoms, while oxygen atoms are created at the same time. Zinc atom and oxygen atom are combined to form ZnO to deposit on a substrate. The stoichiometric properties, deposition rate, transmission properties, surface roughness and film density of the as-deposited film can be altered by adjusting capillaritron ion beam energy and oxygen partial pressure. Using preferred processing parameters, the root-mean-square surface roughness of the as-deposited film can be smaller than 1.5 nm, while the transmission coefficient at visible range can be greater than 80%.

A deposition system supplies a continuous flow of process gases and sequentially selects among the flowing process gases for delivery to a reaction chamber. In the reaction chamber the delivered process gas acts as an ionizing species and thereby effects the deposition of a target substance upon a substrate. Gases not selected for delivery to the reaction chamber are swept away by a vacuum pump. By making a plurality of process gases continuously available, sequentially selecting among the available process gases, and pumping unused gases away before they enter the reaction chamber, such a system and method provides for continuous, sequential, uninterrupted deposition of a variety of substances, while maintaining desired flow rates and chamber pressures.
