Abstract: A wireless sensor array communication system includes a plurality of wireless sensors each including a resonant circuit that is excited by an RF pulse so as to provide a resonant energy proportional to a measurand being monitored. A transceiver of an interrogator system transmits RF pulses to each of the sensors to excite the resonant circuits therein and receives RF signals transmitted from each of the sensors that are indicative of the resonant energy provided by the resonant circuit. A magnet-gradient coil arrangement of the interrogator system generates a magnetic field and selectively applies magnetic field gradients along a number of axes, such that a frequency and phase of the resonant energy provided by the resonant circuit of each wireless sensor is altered responsive thereto, with the altered frequency and phase of the resonant energy being a function of a location of the respective wireless sensor within the magnetic field.

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.
