Latest Patents

Chapman's most recent patent is titled "Method and apparatus for generating a vibrational stimulus." This invention features a vibrotactile transducer that delivers a point-like vibrational stimulus to the user's body in response to an electrical input. The apparatus is designed with a housing that maintains contact with the skin, and it includes a moving mechanical contactor that is preloaded into the skin. The contactor is connected to a toroidal moving magnet assembly, which is suspended by springs within a magnetic circuit assembly that contains a pair of electrical coils. The design ensures that the electromechanical resonance of the assembly is optimized for the frequency range where the human body is most sensitive to vibrational stimuli. By adjusting the drive signal to the transducer and activating it at specific body locations, different information can be conveyed to the user in an intuitive manner.
