Abstract
An expression shoe includes a pedal, a base, and a bearing arrangement rotatably connecting the pedal to the base. A sensor arrangement produces a senor signal corresponding to a rotational position of the pedal with respect to the base. The sensor includes a hall-effect sensor mounted to one of the pedal and the base and a magnetic field producing device mounted to the other of the pedal and the base for producing a linear output signal in response to movement of the pedal relative to the base.
Claims8
An expression shoe comprising:
- a pedal;
- a base;
- bearing means rotatably connecting said pedal to said base;
- sensor means for producing a sensor signal corresponding to a rotational position of said pedal with respect to said base;
- said sensor means comprising a hall-effect sensor mounted to one of said pedal and said base and magnetic field producing means mounted to the other of said pedal and said base for producing a linear output signal in response to movement of said pedal relative to said base;
- wherein said base includes a generally inverted U-shaped channel and a pair of feet extending oppositely outwardly of said channel for accommodating two or more different mounting configurations.
A base for an expression shoe, said base comprising:
- a generally U-shaped channel, and a pair of feet extending oppositely outwardly of said channel for accommodating two or more mounting configurations.
A method of mounting a swell pedal to an organ, said method comprising:
- providing a mounting base having at least two different mounting members for accommodating two different types of mounting configuration, said mounting base having an inverted u-shaped channel and a pair of mounting ears extending oppositely outwardly from an open end of said channel Providing a bearing means rotatable connecting said pedal to said base;
- mounting said base to said organ.
A method of calibrating an expression pedal, said method comprising:
- switching a control system to a calibration mode;
- when in the calibration mode, moving said expression pedal from a full open position to its full closed position;
- the control system recording the movement of said expression pedal from its full open position to its full closed position;
- exiting the calibration mode;
- and
- the control system recording values corresponding to said full open and full closed positions and calculating a proportional output signal.
