Latest Patents

One of Takeuchi's latest patents is for a "Grating transducer for acoustic touchscreens." This invention involves an acoustic touch sensing device that includes a substrate with a surface and an acoustic wave transducer. The device is designed to transduce a bulk wave in the substrate, allowing for the detection of touch through the propagation of waves along the surface. The technology may include scattering centers to couple the bulk wave to a Rayleigh wave or plate wave, enhancing the device's sensitivity to touch.

Another notable patent is for an "Apparatus and method for recognizing speech." This invention focuses on a speech recognition system that employs linear matching techniques. It detects the start point of an input speech pattern and updates the speech frame number accordingly. By generating a plurality of reference templates in a linear relationship to the frame number, the system calculates the dissimilarity between the input pattern and the reference templates, ultimately determining the recognized result of the input speech.
