In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.

Method and system for wear monitoring using RF reflections

A rotorcraft comprising a rotor blade designed to flap about a hinge point, a measurement system designed to measure blade flapping, and a processing system designed to alter blade flapping measurements. The processing system further comprises a correction process to alter a blade flapping measurement dependent on rotor RPM or rotor torque.

Blade flap measurement process

A system includes a slurry pipe and a pipe liner disposed within an inner diameter of the slurry pipe. At least one redundant transducer wear ladder sensor is disposed within the pipe liner. A computer controller is operatively coupled to the at least one redundant transducer wear ladder sensor via a flexible ribbon cable. A radio-wave transmitter is operatively coupled to the computer controller. A radio-wave receiver is operatively coupled to the computer controller. A power source is operatively coupled to the radio-wave transmitter and to the radio-wave receiver.

Method and system for component wear monitoring

A drill-pipe communication assembly includes a first drill pipe segment. A conductor extends at least partially along a length of the first drill pipe segment. An antenna is electrically coupled to the first drill pipe segment. The antenna facilitates wireless transmission of signals from the first drill pipe segment to an adjacent second drill pipe segment.

The present invention relates to a drill-pipe communication assembly. The drill-pipe communication assembly includes a first drill pipe and an insulated tube disposed within, and generally concentric with, the first drill pipe. A male insert is disposed within a first end of the first drill pipe and a female insert is disposed within a second end of the first drill pipe. A conductor is electrically coupled to the male insert and the female insert. The conductor extends along a length of the first drill pipe. The conductor facilitates transmission of electrical signals from the first end of the first drill pipe to the second end of the first drill pipe.
