Abstract: A system is provided for detecting statistical variations and public opinion. The system comprises a respondent interface subsystem for capturing respective opinion values of a set of respondents in relation to a subject matter, said opinion values having respective validity periods associated therewith. The system further includes a database subsystem for storing the respective opinion values corresponding to each respondent and to said subject matter. The system further includes a statistical processing subsystem for calculating successive values of a collected opinion value by selecting respective subsets of said respective user opinion values according to said respective validity periods and calculating said successive values of a collective opinion value over said corresponding subset.

Abstract: The Euclid mutual division arithmetic circuit relating to the present invention comprises first, second, and third register portions and control portion. Each register portion is constituted so as to be able to selectively perform a Euclid mutual division, perform Euclid mutual division using a divisor and dividend, supply the divisor used in the Euclid mutual division operation, and supply the dividend used in the Euclid mutual division operation. The control portion operates so that, in a kth operation, the first register portion supplies the dividend, the second register portion performs the division operation, and the third register portion supplies the divisor supplying function; in a (k+1)th operation, the first register performs the division operation, the second register portion supplies the divisor, and the third register portion performs the dividend.

Abstract: A portable lightweight combination laptop and pad computer has a display mounted on a main housing for movement between a closed position and an open position. In the closed position, a keyboard is covered by the undersurface of the display and the display viewing surface remains visible so that the computer may be used in the pad mode with a conductive stylus for data and command entry. In the open position, the keyboard is exposed so that the computer may be used in a laptop or desk top mode, or in a combined mode including the pad mode. The display is mounted to the housing by a four bar hinge mechanism, and a pair of latches are provided approximately mid-way between the front and rear portions of the housing along the side margins to securely latch the display in the closed position for storage, transit or use in the pad mode.
