Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A speech enhancement system including an auditory stylus and optionally one or both of an earpiece and communication device. The auditory stylus, by itself and/or in cooperation with one or both of earpiece or communication device, provide users with multiple operating mode functions that can enhance the users' ability to understand speech and other sound. Embodiments may operate in one or more of an original speech mode, filtered speech mode, transcription mode or translation mode.

Abstract: 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.

Abstract: A cochlear and nerve stimulation system comprises a signal input to receive an audio input signal, a multiple channel microphone input to receive multiple channel ambient noise signals, and a multiple channel cochlear converter coupled to the signal input to produce multiple channel surround sound cochlear and nerve stimulation signals based on the audio input signal. The stimulation signals include one or both of interaural level differences and interaural time differences. A sound canceling processor is coupled between the microphone input and the cochlear converter to produce multiple channel sound canceling signals based on the ambient noise signals. Multiple channel cochlear and nerve stimulation electrodes are configured for attachment to a user and coupled to receive the multiple channel surround sound cochlear stimulation signals.
