Systems and methods for determining a remaining useful life of an interface of a respiratory therapy system
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.
1 . 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.
2 . The method of claim 1 , wherein the physical feature includes a hole in the interface, and the hole progressively expands over time based on usage.
3 . The method of claim 1 , wherein the physical feature includes a fin on the interface, and the fin progressively dissolves over time based on usage.
4 . The method of claim 3 , wherein the fin is integral with the interface.
5 . The method of claim 3 , wherein the fin is separate and distinct from the interface and coupled thereto.
6 . The method of claim 3 , wherein the fin has a geometrical shape.
7 . The method of claim 6 , wherein the shape has an edge that has a dimension that shortens over time indicating the remaining useful life.
8 . The method of claim 1 , wherein the acoustic signal is generated or emitted at a predetermined interval by a speaker of the respiratory therapy system.
9 . The method of claim 1 , wherein the remaining useful life of the interface is a function of usage by a user of the interface.
10 . The method of claim 9 , wherein the remaining useful life of the interface is further the function of a manufacturing date of the interface.
11 . The method of claim 1 , wherein the comparing includes determining a value associated with the physical feature and comparing the value with a reference value associated with the reference feature.
12 . The method of claim 1 , further comprising presenting the remaining useful life of the interface on a display device of (i) a user device, (ii) a respiratory pressure therapy device, or (iii) both.
13 . A system comprising:
a control system comprising one or more processors; and
a memory having stored thereon machine readable instructions;
wherein the control system is coupled to the memory, and the method of claim 1 is implemented when the machine executable instructions in the memory are executed by at least one of the one or more processors of the control system.
14 . A system for determining a remaining useful life of an interface of a respiratory therapy system, the system comprising a control system configured to implement the method of claim 1 .
15 . A non-transitory computer readable medium comprising instructions which, when executed by a computer, cause the computer to carry out the method of claim 1 .
16 . The method of claim 1 , wherein a dimension of the physical feature progressively changes over time based on usage of the user interface, wherein the reference feature correspond to an initial dimension of the physical feature, and wherein the comparing the physical feature to the reference feature includes determining a current dimension of the physical feature and comparing the current dimension of the physical feature to the initial dimension of the physical feature.
