Abstract: A leak of a cold fluid (e.g., a chilled fluid, or a fluid that is initially pressurized and becomes cold on leakage) is detected using a sequence of Infrared (IR) and Visual (VI) images. Using neural nets, in each of VI and IR image-level features are extracted from images and compared with image-level features from images of different times to obtain motion-enhanced features. The motion enhanced features from VI and IR are then compared to obtain fused features from which the leak is detected. The image-level features may be extracted using a neural net with multiple stages. The motion-enhanced and fused features may be obtained in parallel using the image-level features from the multiple stages, and the leak detection based on the stage-specific fused features.

Abstract: The present disclosure, in one embodiment, relates to a randomizer that includes a starter assembly and a collector. The starter assembly provides participants in a race with a fair start and also provides spectators with a beneficial view of the not only the start of the race, but in some cases, the race itself, including the finish.

Abstract: An electrical power unit or electronic data unit includes an outer housing, a circuit board positioned inside the outer housing, a frame inserted inside the outer housing, and a face plate fitted over the outer housing. The circuit board supports, for example, a high voltage AC electrical receptacle, a low voltage DC electrical receptacle, and a switch, each of which is electrically connected to the circuit board. The frame defines a plurality of outlet openings for receiving respective one of the AC electrical receptacle, the DC electrical receptacle, and the switch. The face plate defines outer receptacle openings that align with respective outlet openings of the frame to provide access to the respective AC electrical receptacle, DC electrical receptacle, and switch.

Abstract: An overhead electrical infeed system includes an overhead mount surface, an electrical cord coupled to the overhead mount surface, an electrical outlet assembly coupled to a distal end portion of the cord having a proximal end portion mounted to the overhead mount surface and a distal end portion spaced from the proximal end portion. At least a portion of the weight of the electrical outlet assembly is supported by the electrical cord. A retractor is positioned along the electrical cord and is operable to raise the electrical outlet assembly or to retain the electrical outlet assembly at a selected elevation. An electrical outlet is electrically energized by the electrical cord and is mounted to the electrical outlet assembly, to provide users with access to electrical or data signals.
