Abstract: A computer-implemented system and method for detecting an anomaly in a pipeline carrying fluids using a Pipeline Inspection Guage (PIG). Provided is a PIG configured to be placed into a fluid within the pipeline including one or more pressure measuring devices configured to receive pressure signals indicative of the one or more pressure parameters within the fluid flowing through the pipeline when the PIG is placed within the pipeline. The PIG includes a computer processor configured to provide detected pressure signals to an edge computing device for comparing the pressure signals to one or more anomaly detection thresholds to determine whether an anomaly event (e.g., a leak) is detected in the pipeline. The PIG computer processor preferably automatically generates an event report upon detection of an anomaly even, and may automatically issue an alert in the form of an event summary describing the anomaly.

Abstract: Provided herein are systems and methods to detect pipeline leaks. The systems and method can identify a pipeline pressure surge by applying a trained convolutional neural network (CNN) model for classifying pipeline pressure measurement images on each sensor site of a plurality of sensor sites, transfer pressure surge information obtained from at least a portion of the plurality of sensor sites to a cloud site, and determine whether the identified pressure surge is a pipeline leak at the cloud site using the pressure surge information. The plurality of sensor sites collect pipeline pressure measurement data. The pressure surge information corresponds to the identified pipeline pressure surge.

Abstract: A time-varying signal is applied to at least one coil in magnetic communication with at least a portion of a vehicle susceptible to deformation responsive to a crash. A sense resistor in series with the at least one coil provides for detecting a current therethrough responsive to a voltage thereacross. The current is responsive to a magnetic condition affecting the magnetic field generated by the at least one coil, responsive to the reluctance of a magnetic circuit with which the at least one coil is in magnetic communication, and responsive to associated eddy currents in proximal conductive elements, responsive to the magnetic field generated by the at least one coil.

Abstract: First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. An output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor, and at least one of the first and second complementary voltage signals is controlled responsive to the output signal so as to provide for attenuating at least one noise signal having a frequency that is substantially different from a frequency of the first and second complementary voltage signals.

A DC bias current in the series circuit is substantially nulled, and an output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor.

A second signal is generated responsive to a voltage across the sense resistor and is response to a magnetic condition of the at least one coil, which is response to the magnetic communication of the at least one coil with the portion of the vehicle.

A voltage across the circuit element is regulated in reference to a predetermined level, and an output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor.

Abstract: Due to the persistence of human vision, moving light sources tend to be perceived not as point sources, but as continuous streaks or arcs of light. Many toys, novelty items, and light show devices make use of this peculiarity of human vision by moving light sources to produce visually striking patterns of light and color. In addition to dedicated devices for this purpose, inventive minds have employed simple household devices such as fans to produce the movement necessary to provide an interesting light show. In the past, these have all relied on electrically operated lights. Unfortunately, complications arise in designing and implementing a means to provide electrical power from a stationary power source to electric lights attached to moving fan blades. Further complications arise in trying to adapt this design to fans of different configurations, sizes, and shapes.
