  • Electronic system for recovering the communication signal of the bottom sensor and tester of the communication module/mmi with the bottom sensor in oil wells operating with SCP
    Patent number: 11994022
    Abstract: An electronic system is capable of assuming the role of master module before the proprietary module of the manufacturer of the SCP system, in the absence of a response to the first request from the supervisory system, or when the proposed module detects that the original module is inappropriately carrying out the PCM signal decoding. The system is further capable of monitoring new variables available at the bottomhole, regardless of the limited set of variables provided by the original module of the SCP system.

  • SINGLE-WALLED CARBON NANOTUBE (SWCNT) FABRICATION BY CONTROLLED CHEMICAL VAPOR DEPOSITION (CVD)
    Publication number: 20140044873
    Abstract: The system and method disclosed herein provide a predetermined, variable volume argon-hydrogen gas mixture for a chemical vapor deposition (CVD)-based process, which enables the growth of single-walled carbon nanotube (SWCNT) structures. The exemplary SWCNT structures of this system and method are fabricated with a degree of control over the field emissions produced by the SWCNT and the range of diameters of each of the SWCNTs. Specifically, the predetermined diameter ranges and the field emissions of the SWCNT structure corresponds to a predetermined range of concentrations of the argon-hydrogen mixture and the argon concentration respectively. The defects and the diameter of the SWCNTs typically contribute to field emissions from the SWCNT structures at low applied voltages.
