Abstract
According to some implementations of the present disclosure, a method for determining a remaining useful life of an interface of a respiratory therapy system is disclosed. Acoustic data associated with an acoustic reflection of an acoustic signal is received. The acoustic reflection is indicative of a portion of a structural shape of the interface. The received acoustic data is analyzed to identify a physical feature of the portion of the structural shape of the interface. The physical feature is compared to a reference feature. Based at least in part on the comparison, the remaining useful life of the interface is determined.
Claims16
A method for determining a remaining useful life of an interface of a respiratory therapy system, the method comprising:
- receiving, via a microphone of the respiratory therapy system, acoustic data associated with an acoustic reflection of an acoustic signal, the acoustic reflection being indicative of a portion of a structural shape of the interface, wherein the acoustic signal is emitted by a speaker of the respiratory therapy system, and wherein the acoustic reflection is a reflection of the acoustic signal off the portion of the structural shape of the interface;
- analyzing the received acoustic data to identify a physical feature of the portion of the structural shape of the interface;
- comparing the physical feature to a reference feature;
- and
- based at least in part on the comparison, determining the remaining useful life of the interface.
