  • Optical Instrument Pickup
    Publication number: 20120304848
    Abstract: An optoelectronic pickup for a musical instrument includes at least one light source which directs light to impinge a string of the musical instrument in at least one photoreceiver located to detect the reflected light, so as to generate an electrical signal that is responsive to string vibrations. A number of different filter approaches are disclosed that can control undesired effects of spurious light. The filter approaches may be structure-based, signal processing-based, and/or optics-based.

  • Optical instrument pickup
    Patent number: 7977566
    Abstract: A optoelectronic pickup for a musical instrument includes at least one light source which directs light to impinge a string of the musical instrument in at least one photoreceiver located to detect the reflected light, so as to generate an electrical signal that is responsive to string vibrations. A number of dissimilar filter approaches are included to control undesired effects of spurious light, the filter approaches may be structure-based, signal processing-based, and/or optics-based.

  • System and method for ultrasonic tomography
    Patent number: 6475150
    Abstract: A system and method for doing both transmission mode and reflection mode three-dimensional ultrasonic imagining. The multimode imaging capability may be used to provide enhanced detectability of cancer tumors within human breast, however, similar imaging systems are applicable to a number of other medical problems as well as a variety of non-medical problems in non-destructive evaluation (NDE).
