Abstract: A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, visible light from an intense visible light source(s) is directed at the resulting glass and thermal imaging is used to detect inclusions based on a temperature difference between the inclusions and surrounding float glass. In another example embodiment, inclusion detection may be performed without exposure of the glass to light from a light source(s).

Abstract: This invention is used to determine the condition of power transformers using real-time on-line high speed measurements. Specifically, a failure prediction method is described. This provides alerts prior to a catastrophic event that could cause major damage to the transformer and resulting business losses. Real time absolute phase angle and frequency as well as real and reactive power measurements from both sides of the transformer are used to estimate frequency domain transfer functions. The transfer functions are in fact the complex admittance functions relating the input and the outputs from the transformer. Three methods of computing the transfer function are outlined in this application. First, the Fast Fourier Transform (FFT) of both the input and the output wave forms are used to compute the transfer functions continuously in real time.
