Abstract: A pipeline monitoring system includes at least one power generating device and at least one information device. The at least one power generating device generates electric power by movement of the fluid in the pipeline so as to power the at least one information device which then sends a signal and the monitors judges the problem of the pipeline according the signal, such that the maintenance is timely provided.

Abstract: Systems and methods for severing elongated material include a rotatable first roll having a first severing structure, a rotatable second roll having a second severing structure corresponding with the first severing structure for severing a length of the filament positioned between the rolls, a drive system operable to independently rotate the first roll and the second roll according to a drive command, a sensor system operable to make measurements and generate actual position signals representative of an actual current rotational position of the first roll and an actual current rotational position of the second roll, and a control system for receiving the position signals and operable to generate the drive command in accordance with predetermined control parameters and based on the actual rotational position signals, wherein the drive command synchronizes the respective rotational positioning of the first roll and the second roll.

Abstract: Systems, devices and methods for applying solution to a filament include an applicator for applying at least a partial coating of a solution to a filament, comprising: an applicator surface operable to at least partially coat a filament with a solution; a first container operable to supply the solution to the applicator surface, a volume of the solution in the first container corresponding to a solution level in the first container; a second container operable to contain a supply of solution in fluid communication with the solution in the first container such that the solution in the second container has a solution level indicative of the solution level of the solution in the first container; and a detector for determining the solution level within the second container, the detector operable to control an adjustment of the volume of the solution in the first container such that the solution level in the first container is maintained within a predetermined range of levels.
