Abstract: A method for operating secure computer processes includes storing a local encryption key in a register of a processor. The local encryption key is stored in a masked state. The method further includes receiving, from a memory communicating with the processor, an operational encryption key. The method includes encrypting the operational encryption key using the local encryption key and an initialization vector to generate an encrypted operation key. The local encryption key is unmasked prior to encrypting the operational encryption key. Further, the method includes storing the encrypted operational key, the initialization vector, and a verification hash value in the memory. The method includes decryption of symmetric operational keys directly to processor registers without using memory. The method includes decryption of asymmetric operational keys. In the method, the asymmetric key material is decrypted temporarily to memory and that memory is sanitized following the use of the key.

Abstract: A method for quantitatively measuring internal defects in an as-cast steel product includes optically scanning at least a portion of a surface of the steel product with a scanning device to create a digital image thereof, analyzing the digital image to calculate a quantitative value for an amount of internal defects therein, and normalizing the quantitative value to a rating according to a standardized scale.

Abstract: A method for quantitatively measuring internal defects in an as-cast steel product includes optically scanning at least a portion of a surface of the steel product with a scanning device to create a digital image thereof. The method further includes thresholding the image in a thresholding engine to isolate internal defects within the image and analyzing the thresholded image to determine an internal defect area, wherein the internal defect area includes an area of at least a portion of the thresholded image that is occupied by the internal defects. The method further includes determining an overall area of the portion of the thresholded image, calculating a fraction of the internal defect area relative to the overall area, and calculating an equivalent Mannesmann scale rating of the internal defects in the steel product based on the fraction.

Abstract: A cover assembly has a plurality of covers that are movable between an open and closed position to cover access openings in a base. The assembly includes a locking assembly for locking one or more of the covers in the closed position. The locking assembly includes a locking tab on the base that has two locking apertures. One locking aperture receives a lock to overlie a front face of each of the covers to prevent the covers from opening. A second locking aperture is oriented to mate with an aperture in a locking tab on one of the covers to lock the cover in a closed position while allowing the other cover to open independently of the other. In another embodiment, one cover has a flange that overlies at least a portion of the other cover so that locking one of covers prevents both covers from being opened.
