Latest Patents

Maxfield holds a patent for a "Grating transducer for acoustic touchscreens." This invention involves an acoustic touch sensing device that comprises a substrate with a surface and an acoustic wave transducer. The transducer is designed to transduce a bulk wave in the substrate, which propagates along an axis intersecting the surface. The energy of the bulk wave is coupled to a wave with a converted wave mode, which has appreciable energy at the surface and propagates along it. The device may also include a set of scattering centers to couple the bulk wave to a Rayleigh wave or plate wave. This technology allows for the detection of touch by analyzing the dispersed Rayleigh wave or plate wave over a region of the substrate.
