Abstract
A compressed fluid source assembly may comprise: a pressure cylinder configured to receive a compressed fluid source therein; and a surface acoustic wave (SAW) sensor coupled to an external surface of the pressure cylinder.
Claims16
An evacuation system, comprising:
- a compressed fluid source comprising an external surface;
- an evacuation slide coupled to the compressed fluid source;
- a surface acoustic wave (SAW) sensor coupled to the external surface of the compressed fluid source;
- a transceiver;
- a display device;
- and
- a controller in electrical communication with the transceiver, the controller configured to:
- determine a pressure in the compressed fluid source based on data received from the SAW sensor,
- compare the pressure to a pressure threshold,
- generate an alert in response to the pressure being less than the pressure threshold, and
- sending the alert to the display device.
