A sensor on an earpiece is used to attempt to detect a signal corresponding to a heartbeat. If a heartbeat is detected, it can be determined that the earpiece is being worn by a user. The sensor may be an acoustic transducer on a surface of the earpiece that is located within the wearer's ear canal, while the earpiece is being worn normally.

Embodiments of the present invention relate to a system and method for measuring intracranial pressure (ICP). Embodiments of the present invention include emitting an electromagnetic wave into the temple area and/or inner ear of a patient and measuring ICP based on the characteristics of the reflected and/or transmitted electromagnetic wave scattered by the tissue and/or cavity. The characteristics may include variations in the electromagnetic wave corresponding to distortions by the cavity within the skull beneath the temple and/or the oval window within the patient's inner ear. Further, embodiments of the present invention include ICP is elevated in the patient. The present invention concentrates on measuring and quantifying the changes in transmission characteristics to determine changes in ICP.

Provided is an ear wearing type sensor probe for measuring oxygen saturation (SpO2). The ear wearing type sensor probe is configured such that the oxygen saturation (SpO2) may be measured while worn in an outer ear canal with abundant blood vessels and close to the heart in the form of an earphone, so that the user's hand may move freely and motion artifact noise may be minimized to measure relatively accurate oxygen saturation (SpO2).

A sleep assessment system includes a blood flow measurement unit and a assessment unit. The blood flow measurement unit acquires first information related to the blood flow of the user. The assessment unit determines the sleep stage of the user based on the first biological information.

A hearing device and subassembly therefor includes a sleeve member configured for at least partial insertion into a user's ear canal, the sleeve member defining a cavity that receives and retains at least a portion of a sound-producing electroacoustic transducer. The sleeve member includes a cable interface, wherein an electrical interface of a sound-producing electroacoustic transducer received in the cavity is accessible via the cable interface. The device also includes on or more sensors integrated with the sleeve member and positioned to sense a biomarker or other condition when the sleeve member is at least partially inserted into the user's ear canal. The hearing device includes conductive traces integrated with the sleeve member, where at least one conductive trace is electrically connected to the sensor and electrically connectable via the cable interface.

The present disclosure relates to a device and method for detection and compensation for an oblique ear-probe insertion in especially hearing testing diagnostic setups. More particularly the disclosure relates to detecting an oblique probe insertion from an ear-probe measurement and estimated characteristic impedances and compensate for its effect on the ear-canal reflectance.

A smartphone and tympanometer-based middle ear abnormality detection mobile system and a method for detecting middle ear abnormalities by a mobile computing device coupled to a tympanometer is disclosed. The method detects middle ear abnormalities by a smartphone-based tympanometer, thereby allowing mobility for medical practitioners to check for middle ear abnormalities in people unable to visit an ENT at a medical facility. The method is implemented as a software application that runs on the mobile computing device and displays results instantly to help determine any of several types of middle ear infection which may be present. This is a huge improvement over existing process where a doctor has to make that determination based on his/her interpretation of the tympanogram.

Embodiments herein relate to ear-wearable devices and systems that can detect a risk of infection in a device wearer. In a first aspect, an ear-wearable infection sensor device is included having a control circuit, a microphone, a sensor package, and an electroacoustic transducer, wherein the electroacoustic transducer is in electrical communication with the control circuit.

The ear-wearable infection sensor device can be configured to analyze data from the sensor package to determine physiological parameters of a device wearer and evaluate the physiological parameters to detect the risk of an infection. Other embodiments are also included herein.

A ring-shaped earphone may be configured to be worn in an ear. When not worn in the ear, the ring-shaped earphone may be conveniently stored on a finger. In one example, the ring-shaped earphone may include a ring-shaped body defined by an outer cylindrical surface and an inner cylindrical surface. The earphone may include a speaker within the ring-shaped body. The speaker may be configured to project sound through a speaker opening in the outer cylindrical surface. The earphone may include a microphone within the housing. The microphone may be configured to receive sound through a microphone opening in the inner cylindrical surface.

A hearable comprises at least one microphone coupled with a wearable structure and a sensor processing unit disposed within the wearable structure and coupled with the microphone. A portion of the wearable structure is configured to be disposed within a user's ear. The sensor processing unit acquires audio data from the at least one microphone and head motion data from at least one motion sensor of the sensor processing unit. The head motion data describes motions of the user's head and comprises cranium motion data and mandible motion data. The sensor processing unit separates the mandible motion data from the head motion data, synchronizes the mandible motion data and the audio data into a synchronized data stream; classifies an activity of the head during a portion of the synchronized data stream; and generates a health indicator for the user based on the activity and the synchronized data stream.
