Apparatus and methods for bone conduction detection are disclosed herein. An example wearable device includes a first sensor positioned to generate first vibration information from a bone structure of a user and a second sensor positioned to generate second vibration information from the bone structure of the user. The first vibration information and the second vibration information include sound data and motion data. The motion data is indicative of a motion by the user. The example wearable device includes a signal modifier to generate a modified signal including the sound data based on the first vibration information and the second vibration information. The example wearable device includes a communicator to transmit the modified signal for output via a speaker.

Provided is an apparatus for bodily sensation of bone vibration. The apparatus includes: an electric signal generator configured to generate an electric signal; an amplifier configured to amplify the electric signal from the electric signal generator; a vibrator configured to transduce the amplified electric signal transmitted from the amplifier into a mechanical vibration; a metal vibration member directly coupled to a vibration generator of the vibrator, the vibration member having a seat portion configured to contact with a human body and a side surface portion continuing with the seat portion; and a seat support member provided on a back surface of the seat portion, covering the vibrator, and configured to be placed on a placement plane and to support the seat portion above and apart from the placement plane so as to keep vibrational energy from being conducted to the placement plane.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (V-VIS) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

Apparatus and methods are described herein that provide a vibratory device that can apply a vibratory signal to a portion of a head of a user such that the vibratory signal can be conducted via bone to a vestibular system of the user and cause a portion of the vestibular system to move in a manner equivalent to that of a therapeutically effective vibratory signal applied to an area overlaying a mastoid bone of the user. The vibratory device can be associated with frequencies less than 200 Hz. The vibratory device can be effective at treating a physiological condition associated with the vestibular system.

A method for providing information to a user, the method including: receiving an input signal from a sensing device associated with a sensory modality of the user; generating a preprocessed signal upon preprocessing the input signal with a set of preprocessing operations; extracting a set of features from the preprocessed signal; processing the set of features with a neural network system; mapping outputs of the neural network system to a device domain associated with a device including a distribution of haptic actuators in proximity to the user; and at the distribution of haptic actuators, cooperatively producing a haptic output representative of at least a portion of the input signal, thereby providing information to the user.

A noise-cancelling earplug assembly is provided, having an ear piece for insertion into the ear canal and a housing removably attached to the ear piece. A hollow core is defined in the housing to receive a sound-selective sound barrier that contains at least one sound filtering element to attenuate sounds reaching the ear drum. An end cap is provided and is attachable to the housing to enclose the sound-selective sound barrier inside the housing. The sound selective sound barrier can be removed from the housing of the earplug and replaced with a different sound selective sound barrier with different sound attenuation characteristics.
