Patent No. 6536440 Method and system for generating sensory data onto the human neural cortex
Patent No. 6536440 Assignee: Sony Corporation (Tokyo, JP); Sony Electronics, Inc. (Park Ridge, NJ) Method and system for generating sensory data onto the human neural cortex (Dawson, Mar 25, 2003) Abstract A non-invasive system and process for projecting sensory data onto the human neural cortex is provided. The system includes a primary transducer array and a secondary transducer array. The primary transducer array acts as a coherent signal source, and the secondary transducer array acts as a controllable diffraction pattern that focuses energy onto the neural cortex in a desired pattern. In addition, the pattern of energy is constructed such that each portion projected into the neural cortex may be individually pulsed at low frequency. This low frequency pulsing is formed by controlling the phase differences between the emitted energy of the elements of primary and secondary transducer arrays. Notes: Method and sys
