Abstract: Systems and methods for managing the power consumption of an oxygen concentrator are disclosed. An oxygen concentration system may comprise a compression system, a canister system, one or more processors, and at least one of a pressure sensor or a movement sensor. The one or more processors may be configured to transition the oxygen concentration system to at least one of a prescribed mode of operation or a standby mode of operation. The timing of the transition may be based on at least one of a number of breaths detected from the pressure signals generated by the pressure sensor or an estimated energy content of the movement signal generated by the movement sensor. A predetermined volume or concentration of oxygen enriched air may be supplied to a user during the prescribed mode of operation. A reduced power may be provided to the compression system during the standby mode of operation.

Abstract: An oxygen concentration system may comprise a pressure sensor, a movement sensor, and a controller configured to use one or more pressure signals obtained from the pressure sensor and a movement signal obtained from the movement sensor to determine when to release a bolus of oxygen enriched air. In some implementations, the controller may adjust a trigger threshold based on an initial pressure signal obtained from the pressure sensor and the movement signal obtained from the movement sensor. In some implementations, the controller may adjust a pressure signal obtained from the pressure sensor based on the movement signal obtained from the movement sensor. In some implementations, the controller may detect a potential onset of inhalation from a pressure signal obtained from the pressure sensor and determine whether to verify the potential onset of inhalation based on the movement signal obtained from the movement sensor.

Abstract: According to one embodiment, a data processing device is described including a non-volatile memory configured to store configuration data for the data processing device, a volatile memory and a control system configured to copy the configuration data from the non-volatile memory to a section of the volatile memory, block writing to the section of the volatile memory and to put the data processing device into a hibernation mode in which the non-volatile memory is inactive and the volatile memory is active.
