Signal egress from a shielding flaw in a cable telecommunication system is detected, even where signals carried by the cable telecommunication system are quadrature amplitude modulated signals that statistically resemble broadband noise by generating a marker signal comprising a double side band, suppressed carrier signal in the fringes of contiguous frequency bands and at a power level which cannot cause perceptible interference with signals in those contiguous frequency bands. The separation of the sidebands comprising the marker signal can unambiguously identify the marker signal and can distinguish between different cable telecommunication systems installed in the same geographic area. The marker signal can be additionally coded by varying the frequency and/or amplitude of the modulating signal used to create the marker signal.

A method for identifying color in a target creates a ratio color space by determining the largest color component value of each pixel in an image and creating a ratio of all of the color component value with the largest component value for each pixel.

The ratio space color components are converted to a black and white image. Color information of adjacent pixels are clumped together to form blobs of the same color. The blobs are filtered by shape, color, location, or orientation and sorted to find targets that consist of a predefined pattern with the desired characteristics.

A computerized technique for program simplification and specialization combines a partial interpretation of the program based on a subset of program functions to obtain variable states with concrete values at a program “neck.” These concrete values are then propagated as part of an optimization transformation that simplifies the program based on these constant values, for example, by eliminating branches that are never taken based on the constant values.

The invention relates to a disaggregation apparatus (1) for identifying an electrical consumer in an electrical network (2). An electrical signature providing unit (7) provides electrical signatures of the electrical consumers (4, 5, 6), and an electrical parameter determining unit (8) determines an overall electrical parameter of the electrical network (2). An identification unit (9) identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures. Since the identification unit identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures, the identification of an electrical consumer does not depend on the detection of an event only. This makes the identification more robust, especially less prone to errors caused by missed events, thereby improving the reliability of identifying an electrical consumer in the electrical network.
