Abstract: Provided is a system for adsorbing a gaseous component comprising nitrogen from a pressurized flow of air containing the gaseous component. The system comprises a first adsorption bed, and a second adsorption bed. Each of the adsorption beds are suitable for selectively adsorbing the gaseous component from the flow of air to produce a product gas having a higher oxygen concentration than that of the air. The system includes an adjustable feed gas supply which alternately supplies the first adsorption bed and the second adsorption bed with the air. The first adsorption bed is supplied with air during a first half cycle of operation of the system, and the second adsorption bed is then supplied with air during a second half cycle of operation of the system. The feed gas supply enables adjustment of at least one parameter relating to the amount or respective amounts of air being supplied to the first adsorption bed in the first half cycle and/or to the second adsorption bed in the second half cycle. A connection and valve assembly is provided between the first and second adsorption beds. The connection and valve assembly diverts a portion of the product gas, produced from the respective absorption bed being supplied with the flow of air during the respective half cycle, to the other adsorption bed. This causes previously adsorbed gaseous component to be released from latter. The released gaseous component then escapes from the system, e.g. to the atmosphere, via a vent. A sensor system determines a measure of the flow rate of waste gas, including the released gaseous component, escaping from the system via the vent. The at least one parameter can be adjusted based on the measure in order to tune the performance of the system. Further provided is a method for operating the system.

Abstract: A suspension system for a compressor assembly is provided. The compressor assembly includes at least one cylinder, at least one inlet fluidly connected with the at least one cylinder, an outlet fluidly connected with the at least one cylinder, and a motor housing. The suspension system includes a suspension member and a frame member. The suspension member includes a first fluid conduit connected with the coupling portion and including a first fluid terminal. The first fluid conduit is disposed in fluid communication with one of the outlet and the at least one inlet of the compressor assembly. The frame member includes a base portion, a first support portion, and a second support portion. A first mounting region is formed between the first support portion and the first fluid terminal. The first mounting region defines a first volume that at least partially encloses the first fluid terminal.

Abstract: The present disclosure describes a system and method for maintaining oxygen purity in portable oxygen concentrators, even with asymmetric generation of oxygen enriched gas volumes from different sieve beds of the concentration system. The present system and method compensate for asymmetric oxygen enriched gas generation using asymmetric delivery of purge volumes. Purge valves are used to deliver the asymmetric purge gas volumes, enables the system to maintain oxygen purity without additional power consumption, even when a portable oxygen concentrator does not include a product tank. The present system and method are configured such that asymmetry in enriched oxygen generation can be monitored and the asymmetric purge gas compensation can be applied independently from other control mechanisms of a portable oxygen concentrator.

Abstract: A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid.
