Abstract: A plurality of remote sensing images of a scene are received. A potential target object can be identified in one of the images, wherein the target object has a low signal-to-noise ratio (SNR). A candidate motion path of the target object can be generated based upon the images. A predicted position of the target object along the candidate motion path is determined for each of the remote sensing images. An image chip is extracted from each of the images, where each image chip is centered about the predicted position of the target object in its corresponding image. A sum image chip is generated based upon the image chips. An indication that the potential target object is an actual object in the images is output based upon a value of a center pixel of the sum image chip.

Abstract: The present disclosure pertains to systems and methods for monitoring a capacitance-coupled voltage transformer (CCVT) in electrical communication with the electric power delivery system, the CCVT comprising a stack of capacitors and an electrical contact to a first ground connection. A first current transformer is disposed between the stack of capacitors and the first ground connection. The current transformer provides an electrical signal corresponding to a current associated with the CCVT. A second current transformer is disposed between a primary winding of a step-down transformer associated with the CCVT and a second ground connection. An intelligent electronic device (IED) in electrical communication with the current measurement devices monitors a ratio of magnitudes from the current transformers at a single frequency. The ratio is compared against an acceptable range. When the ratio exceeds the acceptable range, an alarm is generated.

Abstract: A lithium-air flow battery has minimal cathodic product precipitation, thus extending capacity. The lithium-air flow battery includes a flow electrolyte, flowing proximal to the air cathode, the flow electrolyte having little to no intrinsic lithium ion content. Operation of the lithium-air flow battery generates a lithium-ion concentration gradient across the flow electrolyte, with the lowest lithium-ion concentration adjacent to the air cathode. The extremely low lithium-ion concentration at the cathode, combined with the flow condition at the cathode, results in a minimum of solid product accumulation at the cathode, enabling the cathode to catalyze oxygen reduction for an extended duration.
