Abstract: Signal transducers in electrical communication with shorted leads of current transformers are used to provide monitoring and protection functions to an electric power delivery system. Differential protection is performed by comparing a predetermined threshold against a voltage signal from series-connected leads of signal transducers in electrical communication with shorted leads of current transformers. The signal transducers may be Rogowski coils. Signal transducers in communication with shorted leads may be used to improve safety and increase performance of the current transformers by decreasing susceptibility to saturation.

Abstract: An apparatus and methods are provided for an aesthetic air filter to remove airborne particulate matter from an airstream. The aesthetic air filter comprises a supportive frame and a colored filter medium retained within the supportive frame. The supportive frame orients the aesthetic air filter within a ventilation system. The filter medium removes the particulate matter from air flowing through the ventilation system. The filter medium is treated with a suitable dye, or other substance, that gives the filter medium an aesthetically pleasing appearance. The filter medium may include a color that matches other nearby engine components, such as braided sheaths on hoses and wires, as well as decorative metallic couplings, and the like. The filter medium may be endowed with any of various desirable colors. The supportive frame may include a color that is coordinated with the color of the filter medium.

Abstract: A method for enhancing properties of geophysical data with deep learning networks. Geophysical data may be acquired by positioning a source of sound waves at a chosen shot location, and measuring back-scattered energy generated by the source using receivers placed at selected locations. For example, seismic data may be collected using towed streamer acquisition in order to derive subsurface properties or to form images of the subsurface. However, towed streamer data may be deficient in one or more properties (e.g., at low frequencies). To compensate for the deficiencies, another survey (such as an Ocean Bottom Nodes (OBN) survey) may be sparsely acquired in order to train a neural network. The trained neural network may then be used to compensate for the towed streamer deficient properties, such as by using the trained neural network to extend the towed streamer data to the low frequencies.

Abstract: Described is a transformer end-of-life thermal transmitting indicator (thermal transmitting indicator) that is configured and well suited for monitoring the health of a transformer and communicating the health of the transformer to an end user by way of a cellular transceiver. The thermal transmitting indicator can be configured to alert nearby people of an impending transformer explosion if the transformer fails. The thermal transmitting indicator is also arranged to transmit any problems or impending danger from the transformer to the end user who can then respond by preemptively dealing with the failing transformer. The thermal transmitting indicator comprises liquid sensors spaced in its housing to sense if water or high humidity has infiltrated the housing.
