    Abstract: A system to detect a position of a pipe with respect to a BOP includes a casing disposed around an outer surface of a section of the pipe. The system further includes sensing devices that are disposed on the casing and arranged to form a plurality of arrays and configured to generate position signals. The arrays are disposed circumferentially around the casing and spaced from one another along the length of the casing. The system includes a processing unit configured to compute distance between the pipe and each sensing device. The processing unit generates a first alert when the distance between the pipe and at least one sensing device is different from a reference distance. The processing unit generates a second alert when the distance between the pipe and each sensing device of at least one array of sensing devices is different from the reference distance.

    Abstract: A system for determination of presence of flames is provided. The system includes a photosensitive transducer configured to generate a response signal that is a function of electromagnetic radiation from a flame source. The system also includes a signal processing unit that includes a modulation unit and a demodulation unit.

    Abstract: A fuel flow measuring system includes an ultrasonic fuel flow sensor. The fuel flow sensor includes a first transducer and a second transducer. The first transducer is excited at multiple different excitation frequencies and a voltage, an electric current, and a phase difference between the voltage and the electric current is sensed at the first transducer during excitation. Data points are generated based on the sensed readings and a model is fit to the data points to determine a complex impedance spectrum. The complex impedance spectrum indicates a range of excitation frequencies within a range of a peak resonance frequency of the first transducer. One or more characteristics of excitation signals directed to the second transducer are set based on the determined complex impedance spectrum. In this manner, the signal to noise ratio of ultrasonic signals emitted by the second transducer and received by the first transducer can be maximized.

A sensing circuit measures an electrical response of the sensing system to an alternating electrical current applied to the sensing system at (a) one or more different frequencies, or (b) one or more different resistor-capacitor configurations of the system. One or more processors control a low detection range of the system to the gas, a high detection range of the system to the gas, a linearity of a response of the system to the gas, a dynamic range of measurements of the gas by the system, a rejection of interfering gas analytes by the system, a correction for aging or poisoning of the system, or a rejection of ambient interferences that may affect the electrical response of the system.
