    摘要: Obstructive sleep apnea diagnosis based on peripheral arterial tone (PAT) and real-time magnetic resonance imaging (MRI) is provided. PAT and other physiological data are used to identify respiratory events experienced by a subject with obstructive sleep apnea. MRI images are recorded at least during the respiratory events to identify airway obstructions responsible for the sleep apnea events. The MRI images are recorded in real-time at a high frame rate during the sleep apnea events. The PAT signals and MRI images are collected while the subject is in a sleep state. PAT signals can also be used to identify sleep apnea events and trigger an MRI device to begin recording, thereby reducing the costs associated with recording extraneous and large amounts of MRI data.

    摘要: A hearing aid including a microphone for generating an electrical output from sounds external to a user of the hearing aid, an electrically driven receiver for emitting sound into the ear of the user of the hearing aid, and circuitry for driving the receiver. The circuitry drives the receiver in a self-generating mode activated by a first set of signals supplied externally of the hearing aid to cause the receiver to emit sound having at least one parameter controlled by the first set of externally supplied signals and then drives the receiver in a filtering mode, activated by a second set of signals supplied externally of the hearing aid, with the output of the external microphone filtered according to filter parameters established by the second set of the externally supplied signals. Other forms of the hearing aid, apparatus for supplying the sets of signals to the hearing aid in a total system, and methods of operation are also described.
