  • Precision solid state string motion transducer for musical instruments with non-ferromagnetic strings, and method for precision measurements of time-variable position using 3-pole permanent magnets
    Patent number: 10332499
    Abstract: A single axis position transducer uses an elongate permanent three pole magnet having a radial magnetic field at a spot along the magnet in which the magnetic field has radial field lines that decay as 1/R. R is the distance from the center of the magnet along a radial field line perpendicular to the axis of the magnet. The spot has a first pole of one polarity, and the magnet has poles of the opposite polarity spaced along the magnet on opposite sides of the first pole of the radial magnetic field located at the spot. At least one magnetic field sensor is positioned proximal to the spot along the elongate member that detects the motion of the spot and electrically amplifies the sensor output.

  • Precision solid state position transducer using magnetic fields, method for detecting the position of a spot on an elongate member, and musical instrument
    Patent number: 9679549
    Abstract: The position of an elongate member, such as a string of a musical instrument, e.g. a stand-up bass, is detected by creating a radial magnetic field at a spot along the elongate member in which the magnetic field approximates a disk shape with radial field lines that decay as 1/R. R is the distance from the center of the elongate member along a radial field line perpendicular to the axis of the elongate member. Then the position of the spot is detected using magnetic field sensors that are positioned proximal to and on opposite sides of the spot along the elongate member. Electrically amplifying the outputs of the sensors and detecting magnitude and direction of the motion of the spot from the physical orientation of the sensors do this.
