Patents by Inventor Ioana M. Rizoiu

Ioana M. Rizoiu 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: 5968037
    Abstract: An electromagnetically induced cutting mechanism which can provide accurate cutting operations on both hard and soft materials is disclosed. The electromagnetically induced cutter is capable of providing extremely fine and smooth incisions, irrespective of the cutting surface. Additionally, a user programmable combination of atomized particles allows for user control of various cutting parameters. The various cutting parameters may also be controlled by changing spray nozzles and electromagnetic energy source parameters. Applications for the cutting mechanism include medical, dental, industrial (etching, engraving, cutting and cleaning) and any other environments where an objective is to precisely remove surface materials without inducing thermal damage, uncontrolled cutting parameters, and/or rough surfaces inappropriate for ideal bonding. The cutting mechanism further does not require any films of water or any particularly porous surfaces to obtain very accurate and controllable cutting.

  • Patent number: 5785521
    Abstract: A fluid conditioning system is adaptable to condition the water or air used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The air or water may be conditioned by adding flavor, scent, saline, medications, and disinfectants. In addition to the direct benefits obtained from introduction of these agents, the laser cutting properties may be varied from the selective introduction of the various agents.
