Abstract: A greeting card display device comprising a base and a pair of display modules stacked one atop another and mounted on the base. Each module comprises four upright support panels secured together at adjacent vertical edges, and a plurality of card-supporting tiers secured to the upright support panels. Each of the support panels is in the form of a U-shaped channel section having a pair of side walls and a web wall connected between the side walls. Adjacent vertical edges of the support panels are secured together by securing the side wall of one of the adjacent panels to the web wall of the other adjacent panel. The panels include a plurality of slots which accept tabs on the tiers. Each tier comprises a back, bottom and a front wall connected at adjacent horizontal edges, a pair of securement tabs connected at the upper free edge of the back wall and projecting upwardly and rearwardly, and a pair of securement tabs connected to the lower edge of the back wall and projecting downwardly and rearwardly.

Abstract: A multi-function LED wristwatch in which all the required functions may be performed with the use of only two push button switches. These switches are time demand for displaying hours, minutes and seconds and date demand for alternatively displaying day of month, month of year, AM or PM of time, and day of week. They also perform all the setting functions for these displays and through sequential button depression and digital logic circuits, five of the functions, namely hours, minutes, day of the month, month of the year, and day of the week may be set independently.

Abstract: An improved wristwatch calculator has all of the active circuit elements contained on three chips mounted on the same substrate member in the watch case. A watch chip and a calculator chip each have their outputs connected to a single interface chip consisting of CMOS or I.sup.2 L active elements which multiplex the watch and calculator chip outputs and select the appropriate display as a function of watch mode selection by pushbutton or inertia time demand switches or calculator mode selection by activation of the appropriate calculator keyboard switch on the watch face. The interface chip outputs are connected to six electro-optical display stations.
