  • WEARABLE SYSTEM FOR THE EAR
    Publication number: 20230029042
    Abstract: Methods of measuring biometric characteristics using a sensor positioned in an ear canal of a user are provided. The sensor is positioned on or connected to an ear tip, a contact hearing device, or one or more components thereof. One or more biometric signals may be sensed from the sensor. The biometric characteristic of the user is measured or derived from these sensed signals, and include but are not limited to the temperature of the user, acoustic signal(s) from the user, movement(s) of the user, a ballistocardiogram, an electrocardiogram, oxygen saturation, and blood pressure.

  • Signal processing in physiological noise
    Patent number: 8764676
    Abstract: The invention relates to systems and methods for estimating a response of at least a part of a physiological system to a first deterministic stimulus signal. The methods include separating a measured first signal into a plurality of segments, each segment representing a response of the physiological system to a corresponding portion of the first stimulus signal and generating a template signal representing the plurality of segments. The methods further include calculating a measure of similarity of each segment in the plurality of segments to the template signal to provide a set of scalar quantities, and determining a metric representing a characteristic of the response of at least a part of the physiological system to the first stimulus signal.
