Robert Ogden Crane DUBOIS 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).

  • Pneumatic pressure probe
    Patent number: 11730366
    Abstract: A pneumatic pressure probe comprises an orifice tube extending through a plastic bushing that seals a pressure chamber. The orifice tube has a passage shaped substantially like a converging/diverging de Laval nozzle to reduce turbulence in fluid flow through the probe. More laminar fluid flow reduces noise and inaccuracy in the output of the probe. Laminar flow also reduces user dependent results. The plastic bushing and a specially shaped probe tip reduce extraneous fluid leakages from the probe.
    Type: Grant

  • COMPOSITE OCULAR BLOOD FLOW ANALYZER
    Publication number: 20170245751
    Abstract: A composite ocular blood flow analyzer uses pneumatic tonometric techniques and structures to produce accurate, stable, and repeatable readings of intraocular pressure. A computer processes the intraocular pressure readings to produce data relating to various aspects of ocular blood flow that can be used diagnostically to identify abnormalities in the eye and other parts of the body.
