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.

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.

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 may optically move, at a sampling rate between 50 hertz and 50 kilohertz, one or more apertures anterior to a retina between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. 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.

An implanted microphone is provided that allows for isolating an acoustic response of the microphone from vibration induced acceleration responses of the microphone. The present invention measures the relative motion between a microphone diaphragm, which is responsive to pressure variations in overlying media caused by acoustic forces and acceleration forces, and a cancellation element that is compliantly mounted within a housing of the microphone, which moves primarily in response to acceleration forces. When the microphone and cancelation element move substantially in unison to acceleration forces, relative movement between these elements corresponds to the acoustic response of the microphone diaphragm. This relative movement may be directly measured using various optical measuring systems.

A hearing prosthesis including an actuator. The actuator includes a material that deforms in response to an electrical signal and that is adapted to, upon implantation in a recipient, transmit vibrations representative of a sound signal to an organ of the recipient, wherein the material is at least partially exposed to at least one of body tissue and fluid of the recipient.

An electronic device for a deaf person is provided. The device includes sound sensors arranged at different positions of the electronic device, and configured for sensing an external sound and converting the sensed external sound into sound signals; a processor connected to the sound sensors, and configured for generating a prompt signal when any sound parameters of the sound signals transmitted by the sound sensors meets a prompt condition; a vibrator connected to the processor, and configured for vibrating upon receiving the prompt signals; a first comparator connected to the processor, and configured for, in response of receiving the prompt signal, determining a sound sensor corresponding to a sound signal with a highest intensity, and generating orientation information corresponding to the sound sensor that corresponds to the sound signal with the highest intensity; and an indicator connected to the first comparator, and configured for indicating the orientation information.

The hearing device takes advantage of a simultaneous three-pronged approach that converts sound to electricity and subsequently to vibration and ultrasound. The vibrations and electricity are transmitted via skin nerves to the brain to give the deaf or hard of hearing person hearing sensation through conditional reflex. The ultrasound wave is transmitted wirelessly to skull and then via bone conduction to the brain and inner ear. This hearing device is not solely dependent on the partially or totally damaged or absent inner ear.
