  • Patent number: 11653170
    Abstract: In one embodiment, a method for emitting a sound from an in-ear speaker worn by a subject includes generating, by an audio source of the in-ear speaker, a source audio signal. One or more speakers of the in-ear speaker may emit a sound based on the audio signal and an audio-transport tube of the in-ear speaker may receive the sound. The one or more speakers may be comprised of a singular speaker or a speaker array coupled to a crossover network. The audio-transport tube has an input end coupled to the one or more speakers to receive the sound. An audio reflector of the in-ear speaker may reflect the sound.

  • Publication number: 20230123872
    Abstract: A computer-implemented method of detecting an anomalous action associated with a physical system includes developing, by a computing device a plurality of vectors, each vector indicative of an event that occurred at a specific time within the system, combining, with the computing device each vector that occurred within a predefined time duration into one of a plurality of master vectors, and performing, with the computing device a cluster analysis to group each master vector of the plurality of master vectors into one of a plurality of states. The method also includes determining, with the computing device a real-time master vector based at least in part on one or more events that occur within the predefined time duration, classifying, with the computing device the real-time master vector as a real-time state, and indicating that the real-time state is anomalous when the real-time state doesn't match one of the plurality of states.
