Abstract: The technology involves scaffold structures used for in-ear sensor systems. Such systems that can perform biometric signal detection or act as a human-computer interface. Scaffolding arrangements minimize the amount of material placed in the ear while providing a secure fitting device that can be worn for hours, days or longer in order to provide maximal benefit to the wearer. The scaffolding includes a “C”-shaped arcuate curvature for at least part of the housing. This configuration can act as a natural leaf spring to help maintain the housing in contact with different points along the ear. Sensors are located along various points of the scaffolding for use in different diagnostic situations. Different components of an on-board sensor input and processing system can be distributed along different parts of the scaffolding. Such structures beneficially minimize ambient sound occlusion and avoid the need of an exterior strap or clip worn around the ear.

Abstract: The technology provides a system and method for simulating and detecting bio signals such as brain bio-signals. The technology can be used for medical or non-medical purposes, for instance to simulate or evaluate certain medical conditions using a physical brain-type phantom body. A set of optical fibers provides modulated signals received from an optical signal modulator, which is managed by a controller to generate repeatable signals with high fidelity. The modulated signals are received by a set of emission elements such as photoreceivers or other optical electrodes disposed within or otherwise about the phantom body. The emission elements output electrical signals corresponding to the input modulated optical signals. The electrical signals are detected by a set of sensors. The sensors are coupled to a receiver device that is able to evaluate the electrical signals, such as for an electroencephalograph (EEG), electrocardiogram (ECG), electromyogram (EMG) or magnetoencephalography (MEG) diagnostic system.

Abstract: The technology provides a system and method for simulating and detecting bio signals such as brain bio-signals. Optical fibers provide modulated signals received from an optical signal modulator. The modulated signals are received by a set of emission elements disposed within the phantom body, which output corresponding electrical signals. The electrical signals are detected by a set of sensors and evaluated by a receiver device, such as for an electroencephalograph (EEG), electrocardiogram (ECG), electromyogram (EMG) or magnetoencephalography (MEG) diagnostic system. A controller manages the modulation of light signals so that specific electrical signals can be generated as desired. Because tens, hundreds or thousands of emission elements may be arranged in the phantom body, the controller can manage operation of the optical signal modulator so that the precise physical location of each emission element can be mapped quickly and efficiently. The controller may also detect defective components in a similar manner.

Abstract: The technology relates to fabricating and employing a sensor unit with a malleable housing to obtain various bio-signals detected while the sensor unit is disposed in the wearer's ear canal. A set of sensor contacts is arranged along an exterior ear-contacting portion of the housing. The malleable material can be compressed for insertion into the ear canal, then automatically expanding to contact the ear canal at multiple points. The sensor contacts are distributed along the exterior of the housing to provide an orientation agnostic configuration. The sensor unit is able to be worn for hours, a day or longer. During wear, the contacts can detect EEG and/or MEG-related signal, such as Alpha waves. Other sensors may be included with the sensor unit to supplement the detection of bio-signals. The obtained signals may be processed on-board or transmitted to a remote device for off-board processing.
