  • Systems and methods for moving magnetic resonance imaging
    Patent number: 10222444
    Abstract: A magnetic resonance imaging (“MRI”) system that can be operated while a subject performs, experiences, or otherwise undergoes naturalistic motion. This movable MRI (“mMRI”) system includes a magnet whose position and orientation can be changed while the subject is moving, such that the magnet and subject maintain a substantially fixed spatial relationship relative to each other.
    Type: Grant

  • Mechanical actuator for a vestibular stimulator
    Publication number: 20070100263
    Abstract: An apparatus to stimulate a vestibular system. The apparatus comprises an actuator configured to mechanically stimulate the vestibular system, and a control module coupled to the actuator, the control module being configured to provide a control signal that causes the actuator to stimulate the generation of a stationary nerve signal by the vestibular system.

  • Optical vestibular stimulator
    Publication number: 20070060983
    Abstract: An apparatus to stimulate the vestibular system of an individual. The apparatus comprises an optical stimulator configured to optically stimulate a nerve area affecting a person's balance, and a control module coupled to the optical stimulator, the control module being configured to control the optical stimulator.

  • Sensor signal alignment
    Publication number: 20070055331
    Abstract: Methods and systems, including computer readable mediums, are provided for transforming a measurement made relative to a first reference frame into a corresponding measurement relative to a second reference frame. Sensor signals that are produced by sensors in response to the sensors' motion relative to the first reference frame are transformed using a transformation matrix. The transformation generates corrected sensor signals that are relative to the axes of the second reference frame.
