Provides methods, apparatus and systems for compressing a large number of continuous location data of moving objects. In order to convert an interlaced video signal having 525 scanning lines into another progressive video signal having 525 scanning lines while maintaining the image size, in an odd-numbered field, a line after conversion is offset by 0. The apparatus also includes an enclosure system connected to the central collection section such that an operator can enclose a peripheral portion of the central collection section around the interior portion. The design tool can determine, based on the indicated component and on the determination that the subsequence indicates at most one transition, an output sequence of signal transition representations derived from the input sequence of signal transition representations. The resulting conductivity output may be used to add one or more component.
