Sony

http://arstechnica.com/news.ars/post/20050407-4785.html Reuters is reporting that Sony recently got a pie-in-the-sky patent on using ultrasonic waves to beam sensory perceptions, like sights, sounds, and smells, directly into the brain. So in a sense, Sony’s patent is an improvement on The Matrix and the traditional cyperpunk notions of a sensory-enabled network that inspired it, because Sony’s method is non-invasive and doesn’t require you to “jack in.” I suppose you could say it’s “wireless,” to use a current buzz word.
