Abstract: Disclosed is a data entry and display system for loading any one of N digits into any position of an M position data bus where N and M are integers. The system includes a set of N pushbutton switches each of which is representative of one of the digits; and a set of M pushbutton switches each of which corresponds to one of the M positions on the data bus. The system is operated simply by first pushing one of the N pushbutton switches which corresponds to the digits to be loaded; and by subsequently pushing one of the M pushbutton switches which corresponds to the desired digit position. This sequence is repeated for each digit to be loaded. A total of M identical circuits, one circuit for each digit positions in the data bus, operate in parallel to sense the pressed pushbuttons and to take the appropriate bus loading and bus displaying action.

Abstract: A kite having a flying surface of flexible plastic sheet material supported from a single vertical rib and one or more cross-ribs. The ribs are attached to the sheet material at the left, right, upper and lower terminal portions of the sheet material by pockets of flexible material that are bonded to the sheet material. The cross-rib is a solid aluminum rod of uniform diameter which is biased into a symmetrical bend. An adjustable bridle is provided comprising upper and lower bridle members. The upper bridle member also serves as a point of attachment for the cross-rib to the vertical rib. The bridle incorporates centering beads on the end loops of the bridle members. The end loops are received over the vertical rib. The centering beads act to equalize and align the forces transferred to the kite string.
