Abstract: Aspects of the present disclosure provide methods and apparatuses for estimating a biometric parameter using multiple sensors. As described herein, multiple sensors are strategically used to output with increased confidence a biometric parameter. Multiple sensors are strategically used to save power while determining an accurate biometric estimation. Additionally, multiple sensors are used to detect and categorize a sleep apnea event.

Abstract: Aspects of the present disclosure provide methods and apparatuses for determining a subject's PPG based on a signal collected in-ear. Based on the PPG, one or more biometrics are determined including a heart rate, HRV, RR, SpO2 level, blood pressure, blood glucose level, or hemoglobin A1C level. RR and SpO2 are used to determine the presence of a sleep apnea event. The methods and apparatus of determining the subject's PPG described herein are continuous and non-invasive.

Abstract: Aspects of the present disclosure provide methods and apparatuses for determining if a BTE portion of a hearing assistance device is determined to be either a “good fit” (i.e. placed correctly) or “bad fit” (i.e. placed incorrectly). The hearing assistance device includes a sensor in the BTE portion of the device. The sensor measures acceleration due to gravity in one or more of the x, y, and z directions, or any combination thereof. The measured acceleration is input into a pre-trained classifier model that outputs whether the BTE portion is placed correctly or not placed correctly. At least one of the hearing assistance device or a user device in communication with the hearing assistance device provides feedback regarding the positioning of the hearing assistance device. In aspects, the hearing assistance device or the user device guides the user to properly adjust placement of the BTE portion of the device.

Abstract: Aspects of the present disclosure provide methods and apparatuses for determining a subject's sleep stage based on a PPG signal measured using an in-ear earpiece. In aspects, one or more physiological signals are estimated based on the PPG. Based, at least in part, on the determined sleep stage, one or more outputs are provided. In an example, the outputs are provided to the subject, the subject's physician, the subject's clinician, the cloud, and/or a device external to the apparatus. The methods and apparatus of determining the subject's sleep state described herein are continuous and non-invasive and eliminate the need for a clinical setting.

Abstract: Aspects of the present disclosure provide an audio product for obtaining biologically-relevant information associated with a user comprising. The audio product includes at least two electrodes, a processor, and an electroacoustic transducer coupled to the processor. The processor is configured to receive at least one signal affected by an action of the user obtained via the first electrode or the second electrode and take one or more actions based on the at least one signal. The at least one action may control another device, in an effort to provide hands-free control of the other device.

Abstract: Aspects of the present disclosure provide a wearable audio product for obtaining biologically-relevant information associated with a user comprising. The audio product comprises a first electrode placed over the user's auditory cortex on a first side of the user's body, a second electrode placed on the first side of the user's body, a first reference electrode placed on the first side of the user's body, a processor coupled to the first, second, and first reference electrode, the processor configured to take one or more actions based on signals received from the first, second, and first reference electrodes, and an electroacoustic transducer coupled to the processor. Any or all of the electrodes described herein may include any integer number of electrodes clustered in the specified location.
