Patents by Inventor Francisco G. Sanchez

Francisco G. Sanchez 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: 7669469
    Abstract: The present invention provides an apparatus and method for continuously monitoring the integrity of a pressurized well bore fluid sample collected downhole in an earth boring or well bore. The CDR continuous by measures the temperature and pressure for the down hole sample. Near infrared, mid infrared and visible light analysis is also performed on the small amount of sample to provide an on site analysis of sample properties and contamination level. The onsite analysis comprises determination of gas oil ratio, API gravity and various other parameters which can be estimated by a trained neural network or chemometric equation a flexural mechanical resonator is also provided to measure fluid density and viscosity from which additional parameters can be estimated by a trained neural network or chemometric equation. The sample tank is overpressured or supercharged to obviate adverse pressure drop or other effects of diverting a small sample to the CDR.

  • Patent number: 5367521
    Abstract: The present invention provides a telecommunications packet switching system including a hardware portion and a software portion forming an advanced multiprocessing, multiprocessor system (including multiple processors, capable of running more than one process at a time). The hardware and software structures are fully distributed and fault-tolerant, providing a flexible configuration and remote management through the network itself, managing the switching and transmission of messages split into packets, including use of different specific protocols. The system can be connected to a variety of different networks, allowing a large concentration of low speed lines. A control station executes operational functions, and a terminal allows interaction with the system. A DC/DC converter is provided at each element in the processing unit.
