Abstract
Systems and methods are provided for displaying status of a gas concentrator. The systems and methods include, for example, a display having a plurality of illuminable segments. The illuminable segments can be illuminated to form one or more displays indicating system status. The system status includes, for example, warmup, normal operation, low priority alarm(s), high-priority alarms, etc. In one embodiment, the systems and methods also read oxygen values of the gas concentrating system as one basis for determining system status. Other bases are also disclosed.
Claims20
A gas concentrating system comprising:
- a controller;
- a display in communication with the controller;
- the display comprising:
- a plurality of illuminable segments arranged in a radiating pattern;
- and
- logic illuminating at least one of the plurality of illuminable segments according to one of a plurality of patterns based on system status.
A gas concentrating system comprising:
- a controller;
- a display in communication with the controller;
- the display comprising:
- a plurality of illuminable segments arranged in a radiating pattern;
- and
- logic illuminating the plurality of illuminable segments according to one of a plurality of patterns indicating system status.
A method of displaying one or more status indications for a gas concentrating system, the method comprising:
- illuminating during system warmup one or more segments of a plurality of illuminable segments in a rotating pattern;
- reading an oxygen concentration;
- and
- based on the read oxygen concentration level, illuminating one or more segments of the plurality of illuminable segments to display one of a plurality of status indications.
