  • Patent number: 11399775
    Abstract: In some embodiments, features related to inter-beat intervals (IBI) detected by a PPG sensor of a wearable device are extracted and provided to a cardiovascular classifier in order to detect likely instances of a cardiac condition such as atrial fibrillation. Some embodiments use features related to the entropy of the IBI data to improve the predictions generated by the cardiovascular classifier. In some embodiments, co-information between the IBI data and IBI data gathered from healthy and AF populations is determined in order to derive features that represent the probability that a given sample of IBI data represents AF or a normal sinus rhythm. In response to determining likely instances of AF based on these features, the wearable device may obtain clinically acceptable data, such as an ECG, to be transmitted to a separate device for review by a clinician.

  • Patent number: 11376431
    Abstract: An exemplary sound processor within a cochlear implant system directs a cochlear implant to concurrently apply first and second pulses by way of first and second electrodes disposed on an electrode lead configured to be inserted into a cochlea of a patient. The first and second pulses have substantially equal magnitudes and opposite phases such that the application of the first and second pulses forms a dipole that generates a field. The sound processor further directs the cochlear implant to detect, by way of a third electrode disposed on the electrode lead, an energy magnitude of the field that reflects from cochlear tissue located within the field. Based on a difference between the detected energy magnitude of the field and a baseline energy magnitude of the field, the sound processor determines a proximity of the electrode lead to the cochlear tissue. Corresponding systems and methods are also disclosed.
