  • Patent number: 10073441
    Abstract: A system for managing an oxygen generating system including an oxygen storage tank, a compressor, and groups of at least one oxygen generator, wherein the oxygen generating system is configured for supplying a sustained flow of a gaseous mixture comprising mostly oxygen. The system includes at least one controller device. The at least one controller device is configured to control group circuits based at least upon a pressure. Each of the group circuits are for providing power to a particular group of the groups of at least one oxygen generator. The at least one controller device is also configured to control a circuit for providing power to the compressor.

  • Patent number: 9372488
    Abstract: A controller device for managing an oxygen generating system. The controller device is configured to: receive a first pressure signal associated with a first pressure; determine the first pressure to be less than or equal to a startup threshold pressure, said first pressure associated with a pressure of an oil-less tank; send a signal to switch a first circuit on, said first circuit for providing electrical power to a bank of oxygen generators; send a signal to switch a second circuit on, said second circuit for providing electrical power to an oil-less air compressor; receive a second pressure signal associated with a second pressure; determine the second pressure to be greater than or equal to a shutoff threshold pressure, said second pressure associated with a pressure of the oil-less tank; send a signal to switch the first circuit off; and send a signal to switch the second circuit off.

  • Patent number: 9139434
    Abstract: Apparatus and method for managing an oxygen generating system configured for supplying a sustained flow of oxygen, which may include a control box. The control box may include an oil-less air compressor configured to pump the oxygen to an oxygen storage tank from at least two banks of at least one oxygen generator. The control box may include or be connected to a pressure sensor associated with the oxygen storage tank. The control box may further include one or more controller devices configured to control at least two circuits for providing power to the at least two banks of at least one oxygen generator. The one or more controller devices may be configured to switch on or off each bank of oxygen generators in response to particular threshold pressures associated with the storage tank. The one or more controller devices may also be configured to control the oil-less air compressor.
