Abstract: Pressure-controlled transitions are provided for single-note lines in electronic musical instruments. By addressing the relative pressure for two or more pressure points on a playing surface, the method and system provides the performer with the ability to control transitions, such as retrigger, legato, and portamento, with greater precision and flexibility. In particular, the performer's fingers (or another source of pressure) are able to control the manner in which a note transitions from one pitch to another.

Abstract: A system and method for correction of finger positions for an electronic musical instrument. By adding a correction step in the direction of a nearest grid value, the system can perform correction in a manner that allows for gradual position correction while maintaining a vibrato or glissando shape that is similar to vibrato or glissando shape of the actual finger positions over time. The system and method may be used for pitch correction for a continuous-pitch electronic musical instrument.

Abstract: A method of localizing a medical tool, the method comprising: (1) generating an image of a reference target with a camera that is attached to a medical tool, wherein the reference target is remote from the medical tool and located in a room at a known position relative to a coordinate system; and (2) determining the position of the medical tool relative to the coordinate system at least partially on the basis of the generated image of the reference target. Examples of medical tools that can be localized in accordance with the present invention include medical imaging devices, surgical instruments, and bite blocks.

Abstract: An apparatus and method for continuous keyboard system. The Continuous Music Keyboard resembles a traditional keyboard in that it is approximately the same size and is played with ten fingers. It also resembles a fretless string instrument in that it has no discrete pitches; any pitch and any tuning may be played, and finger movements produce smooth glissandi and vibrato. The Continuous Music Keyboard comprises a plurality of rods, each of which has a magnet on each end. The displacement of each rod is measured through mounted Hall-Effect sensors. The sensor values are then analyzed to identify the three-dimensional location of the fingers depressing upon a control surface. Additionally, predictive analysis is conducted on values collected to identify whether a new depression on the control surface has occurred, or rather if a previously placed finger is simply moving alone the Continuous Music Keyboard.

Abstract: The present invention, the Continuous Music Keyboard, is my alternative to a traditional MIDI keyboard. It is a new music performance device that allows the performer more continuous control than that offered by a traditional MIDI keyboard. It resembles a traditional keyboard in that it is approximately the same size and is played with ten fingers. Like keyboards supporting MIDI's polyphonic aftertouch, it continually measures each finger's pressure. It also resembles a fretless string instrument in that it has no discrete pitches; any pitch and any tuning may be played, and finger movements produce smooth glissandi and vibrato. It also tracks front-to-back position of each finger, providing another dimension of continuous control over synthesis. The Continuous Music Keyboard's output can be used to control any synthesis technique.
