Patents by Inventor Yudistira Virgus

Yudistira Virgus 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).

  • Patent number: 10983230
    Abstract: Parallel dipole line (PDL) trap seismometer and vibration sensors are provided. In one aspect of the invention, a seismometer is provided. The seismometer includes: at least one PDL trap having a pair of dipole line magnets, and a diamagnetic object levitating above the dipole line magnets; and a sensing system (passive or active sensing) for determining a position of the diamagnetic object relative to the dipole line magnets and to yield the seismic signal in terms of displacement or acceleration. Methods for sensing vibrations using the present PDL trap seismometer and vibration sensors are also provided.
    Type: Grant

  • Patent number: 10627330
    Abstract: Techniques for gas analysis using a parallel dipole line (PDL) trap viscometer are provided. In one aspect, a gas analysis system is provided which includes: a PDL trap including: a pair of diametric cylindrical magnets, and a diamagnetic rod levitating above the magnets; and a motion detector for capturing motion of the diamagnetic rod. The motion detector can include a digital video camera positioned facing a top of the PDL trap so as to permit capturing video images of the diamagnetic rod and the system can include a computer for receiving and analyzing video images from the video camera. Methods for measuring gas viscosity and pressure using the PDL trap system are also provided.
