A method for providing galvanic vestibular stimulation corresponding to accelerations in scenes of a video. Embodiments include (1) receiving a three dimensional video signal including three dimensional video angular velocity information, (2) receiving a three dimensional head orientation signal including three dimensional head angular velocity information, (3) calculating resultant three dimensional angular velocity information based on the video angular velocity information and the head angular velocity information, (4) calculating three dimensional acceleration information based on the resultant three dimensional angular velocity information, and (5) generating three dimensional galvanic vestibular stimulation signals corresponding to the resultant three dimensional angular acceleration information, wherein the three dimensional stimulation signals will stimulate three dimensional acceleration sensations corresponding to accelerations on the user viewing the displayed scenes.

Techniques for generating and administering an oculo-cognitive addition test. Some aspects include identifying, by a system, a set of numbers that are to be displayed to a user during a trial of a cognitive test. The set of numbers includes at least two numbers. The system can administer the trial of the cognitive test, including, for each number in the set of numbers: displaying the number at a particular position of a display environment; tracking, by the system and using one or more optical sensors, eye movement of the user seeking the number in the display environment; and receiving, by the system and after having displayed the number for a time, a command that is to advance or end the cognitive test.

Oculo-cognitive addition testing

An electrode includes a body and a breakable container of contact-enhancing fluid on or in the body. The container is impermeable to the fluid, and is breakable in response to physical manipulation of the electrode to disperse the fluid into the body.

This document provides methods and materials for treating hypocapnia. For example, methods and materials for delivering COto a mammal to treat hypocapnia or compensate for a reduced level of COare provided.

Methods and materials for treating hypocapnia

A method for operating a computer system to generate and display multidimensional data. A set of multidimensional data points and a selected deviation range is received at a processor. The processor processes each data point to determine its value about the selected deviation range. Display data representative of data point indicia of the determined data point values at circumferentially spaced locations and with respect to an origin in a coordinate system is generated and stored by the processor. The data point indicia for the multidimensional data points are at circumferentially spaced locations, and a radial distance of the indicia with respect to the origin represents the determined data point values. A visual display of the display data can be produced on a printer or monitor.

Computer system and method for diagnostic data display

A speech intelligibility system. Embodiments comprise a talker unit, a listener unit and an earpiece. The talker unit includes a microphone to receive audible speech content and to produce electrical signals representative of the speech content, and a transmitter coupled to the microphone to produce wireless transmissions containing the speech content. The listener unit includes a receiver to receive the wireless transmissions and to produce electrical signals representative of the speech content. At least one of the talker unit and the listener unit includes an amplifier to amplify spectral components of the speech content within a frequency range having a lower end between about 800 Hz and 1,700 Hz and an upper end between about 7,000 Hz and 11,000 Hz. The earpiece is coupled to the listener unit and includes a speaker to produce audible speech content having the amplified spectral components and a tube to direct the audible speech content from the speaker toward a user's ear canal.

Speech intelligibility enhancement system

A system for determining the resistance of peripheral vasculature including a sensor configured to generate output signals proportional to the amount of blood in the peripheral vasculature over time, and a computer subsystem configured to determine the resistance of the peripheral vasculature in response to the output signals.

System and method for determining a measure of the resistance of peripheral vasculature

A system for suppressing vestibular activity of a human subject includes an electronics module configured to generate one or more electrical stimulation signals. A plurality of electrodes each placed proximate a predetermined location on a head of a human subject is configured to deliver the one or more electrical stimulation signals to the predetermined location to suppress vestibular activity of the human subject.

The present invention relates to systems and techniques for stimulating a user. For example, materials and methods for manipulating nystagmus and the related vestibular system with coupling of galvanic vestibular stimulation (GVS) and visual cueing are provided herein. Use of GVS within the present invention may be applied to simulation, alleviating motion sickness, and directional cueing of a user to a precise target location.
