Patents by Inventor Raffi SAHUL

Raffi SAHUL 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).

  • Temperature and field stable relaxor-PT piezoelectric single crystals
    Patent number: 9673380
    Abstract: The application is directed to piezoelectric single crystals having shear piezoelectric coefficients with enhanced temperature and/or electric field stability. These piezoelectric single crystal may be used, among other things, for vibration sensors as well as low frequency, compact sonar transducers with improved and/or enhanced performance.
    Type: Grant
    Filed: November 24, 2014
    Date of Patent: June 6, 2017

  • Transverse mode multi-resonant single crystal transducer
    Patent number: 9070865
    Abstract: A transducer is disclosed that includes a multiply resonant composite, the composite having a resonator bar of a piezoelectric single crystal configured in a d32 transverse length-extensional resonance mode having a crystallographic orientation set such that the thickness axis is in the <110> family and resonance direction is the <001> family.
