  • Publication number: 20260026707
    Abstract: In some embodiments, a spectral tensor technique includes the steps of generating a power spectrogram and a phase spectrogram for the breath triplet; removing high frequency bins from each spectrogram; generating a spectral image by sizing each spectrogram to a pre-determined size; and assembling the spectral images generated for each breath triplet into the spectral tensor. Spectral tensors may be utilized as input to train a pathologic breath detection model. Spectral tensors may also be utilized by a pathologic breath detection model to analyze a new waveform that may or may not include a pathologic breath/pathologic breathing pattern.

  • Publication number: 20160190793
    Abstract: A surge protector assembly includes an electronic device. A housing has a bottom side, a top side and a peripheral wall extending therebetween. The top side is open. A breaker is positioned within the housing. The breaker is coupled to an upper surface of the bottom side. A first cord extends through a back side of the peripheral wall and is electrically coupled to the breaker. The first cord has a distal end with respect to the housing. The distal end has a first plug electrically coupled thereto. The first plug is electrically coupled to a power source. A second cord extends through a front side of the peripheral wall and is electrically coupled to the breaker. The second cord has a distal end with respect to the housing. The distal end of the second cord has a second plug electrically coupled thereto. The second plug is electrically coupled to the electronic device.
