  • Patent number: 10962336
    Abstract: A system for scoring darts that includes multiple cameras placed substantially parallel to the surface of a dartboard. With a field of view extending across the board, the cameras can be configured to capture images of darts projecting outwardly from the board as they are thrown, and the system can use this image data to calculate the location of each dart, and the corresponding score. Various algorithms may be used to orient the system and calibrate the system to account for irregularities in the images captured by the cameras to accurately determine the location. Proper scoring may be achieved for a variety of dartboards with different patterns of scoring regions based on game rules and corresponding board configurations maintained by the system.

    Abstract: Sensor structure (16) is provided for online monitoring of levels of Furans in oil of a transformer tank. The sensor structure includes a UV light source (26), a filter (30) permitting only UV light of a certain wavelength range to pass, a window (32) permitting the filtered UV light to passes there-through and a UV light detector (36) to receive UV light that passes through the window. When the sensor structure is mounted to the transformer tank that is online so that the window is exposed to oil, and Furans in the oil are being monitored, the Furans will absorb UV light, creating a difference in UV light received by the light detector when compared to the UV light received by the light de tector when the monitored oil has no Furans therein. The output signal of the light detector is substantially proportional to a total of Furans in the monitored oil.
