John Glowka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10984773
    Abstract: An electrically amplified percussive instrument has at least one tone bar having a bottom side and fundamental nodes each of the fundamental nodes defined by a channel. A permanent magnet on the bottom side of the tone bar is proximal to one of the fundamental nodes and not aligned with a location of maximum tone bar vibration. A pickup coil positioned underneath the tone bar is aligned with the first permanent magnet and in electrical communication with an amplifier.
    Type: Grant

  • Publication number: 20160225354
    Abstract: A portable component marimba comprising a frame having two opposing sections facing each other. A resonator support rack held in place by gravity extends between the two frame sections. A resonator assembly having a linearly arranged series of resonators extends between the two frame sections and is engaged with the resonator support rack by means of two lateral support brackets. A tone bar assembly extends between the two frame sections and includes a linear series of tone bars interconnected by two lateral laces and is supported by a tone bar support rack. The laces may be tied off on cleats located on the crossbeams. The tone bar support rack may include dampening lace support brackets. The resonator assemblies may incorporate balanced resonators. The tone bars may include sustained dampeners.
