Title: Innovations of James R. Tomashek: A Pioneer in Submersible Pump Telemetry Systems
Introduction
James R. Tomashek, an accomplished inventor based in Wood Dale, IL, has made significant contributions to the field of submersible pump technology. With a total of nine patents to his name, Tomashek has demonstrated a deep commitment to innovation and practical applications that enhance functionality and efficiency in well pumping systems.
Latest Patents
One of Tomashek's noteworthy innovations is the "Multiplex Submersible Pump Telemetry System." This revolutionary system is designed for monitoring parameters such as pressure and temperature in the vicinity of the motor of a submersible well pump. The system features a downhole assembly that includes a transmitter, which generates a carrier signal superimposed onto the power cable. Transducers within the assembly sense physical parameters and produce a change in resistance that corresponds to these parameters. This signal modulation allows the system to provide real-time data for monitoring and analysis.
Another significant patent is the "Submersible Pump Telemetry System," which similarly focuses on monitoring pressure and temperature near the pump motor. Utilizing a transmitter and transducers, this innovation modulates the signals based on the electrical responses received from the sensed parameters. The modulated signal is then transformed at the surface into a readout that indicates the corresponding physical parameters.
