Description:
BACKGROUND OF THE INVENTION
Calendar watches have hitherto shown the day of the week by means of a geared day wheel which is mechanically driven. With the advent of the electrically powered watch, where the source of power is a battery, and where the battery is also used for activating an electrical display system, it becomes urgent to conserve power so that the use of a mechanically driven day wheel no longer conforms to the needs of the system. As a result, electrical display systems based on the use of liquid crystals or light-emitting diodes have been developed. Here, another problem arises, namely that it is desired to minimize the size of timepieces, and, particularly, of wrist watches. This limits the display space available. Consequently, a display system having seven pairs of two letters each would require an inordinately large area on the face of a timepiece. What is needed, then, is a display system so constructed that only a relatively small area is necessary for showing the seven combinations of two letters corresponding to the seven days of the week.
SUMMARY OF THE INVENTION
Pairs of letters corresponding to the days of the week are constructed in selectively activatable segments. At least one segment and preferably a plurality of segments are so arranged that said one segment can be used in the formation of a plurality of letters. The use of even one segment in the formation of more than one letter decreases the space needed for displaying the letters corresponding to the days of the week and the arrangement of said segments in such a way that a plurality of segments can be used in the formation of more than one letter results in a substantial decrease in the area required for said display. Suitable modifications are shown by which the system can be adapted to function in any of a number of languages.
The display systems are electrically activated; both liquid crystal display units and light-emitting diode units are suitable for use in forming the letters in accordance with the present invention.
Accordingly, an object of the present invention is to provide an improved electrical display system for a timepiece wherein the first two letters of any day of the week can be displayed and the space used for the display of said letters is less than would be required if it were necessary to provide separate space for each of the pairs of letters.
Another object of the present invention is to provide an improved electrical display system for showing the days of the week in a timepiece, wherein the letters used for said display are at least partly divided into segments.
A further object of the invention is to provide an improved electrical display system for a timepiece for showing the days of the week, wherein at least one of the segments into which said letters are divided may be used in the formation of a plurality of letters.
Yet another object of the present invention is to provide an improved electrical display system for showing the days of the week in a timepiece wherein the letters to be shown are divided into three groups with respect to the segments used for displaying said letters.
An important object of the present invention is to provide an improved electrical display system for a timepiece adaptable for showing the initial letters of the days of the week in one of a number of languages other than English.
Still other objects and advantages of the invention will in part be obvious and will be apparent from the specification
The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
BRIEF DESCRIPTION OF THE DRAWINGS
For a fuller understanding of the invention, reference is had to the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is an arrangement of segments in accordance with the present invention for showing in English the days of the week in a timepiece electrically;
FIG. 2 shows how the first two letters of each day of the week appear when appropriate segments as in FIG. 1 are selectively activated;
FIG. 3 is an arrangement of segments in accordance with the present invention for showing in French the days of the week in a timepiece electrically;
FIG. 4 shows how the first two letters of each day of the week appear when appropriate segments as in FIG. 3 are selectively activated;
FIG. 5 is an arrangement of segments in accordance with the present invention showing in German the days of the week in a timepiece electrically;
FIG. 6 shows how the first two letters of each day of the week appear when appropriate segments as in FIG. 5 are selectively activated;
FIG. 7 is an arrangement of segments in accordance with the present invention for showing in Spanish the days of the week in a timepiece electrically; and
FIG. 8 shows how the first two letters of each day of the week appear when appropriate segments as in FIG. 7 are selectively activated.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In order to be able to represent the initial two letters of all seven days of the week in English, it is necessary that the capital letters S, M, T, W and F be presented, and that the lower case letters u, o, e, h, r and a be represented. Furthermore, as is evident, appropriate letters must be contiguous so that the combinations Su, Mo, Tu, We, Th, Fr and Sa must be shown with the lower case letter following immediately after the capital. As aforenoted, to place all seven pairs of letters separately on a dial would require the occupation of too great a space. Reduction in space is achieved by dividing a number of the letters into segments and arranging for the use of at least one segment and preferably a plurality of segments in more than one letter or combination of letters.
A particularly good solution to the problem using the above principle is shown in FIG. 1. Group 11 consists of segments which overall has a shape which is close to "Tu, Fr." The group is divided into the segments 21, 22, 23 and 24 in which segment 23 is h-shaped. The shape is achieved by reason of the fact that segment 23 actually consists of two portions 23a and 23b which are electrically connected by lead 23c. To display the combination "Tu", segments 21 and 22 are activated. To display the combination "Th", segments 22 and 23 are activated. For the combination "Fr", segments 23 and 24 are actuated. It will be noted that segment 24 consists of two portions 24a and 24b connected by the electrical lead 24c. As can be seen from this description, group 11 occupies approximately the space which would normally be utilized for presenting only three letters. However, group 11, by selective activation of the proper segments, actually achieves the feat of presenting six letters (two of which are the same) in the space ordinarily needed for the presentation of three letters.
Group 12 is divided into three sets of segments, 25, 26 and 27. Each of the segments is further divided as can be seen from FIG. 1. For displaying "Mo", segments 25 25a 26 and 26a are activated. For displaying "We", segments 26 26a 27 and 27a are activated. Thus, sections 25, 26 and 27 together with 25a, 26a and 27a display four letters in the space normally occuplied by two.
Finally, group 13 consists of segments 28 and 29. For the display of Su, only segment 28, which is divided into two portions electrically connected, is activated. For the display of Sa, both segments 28 and 29 are activated. In the case of group 13, four letters (two of which are identical) are displayed in the space normally used by two.
It will be noted that the number of leads from the segments to a power source (not shown) needed is only nine, whereas fourteen leads would be needed if the letters were unsegmented and were placed side by side. Also, a plurality of segments are used in more than one letter.
Looking at the configuration of FIG. 1, it can be seen that the fourteen letters which would be required in the conventional arrangement, have been compressed into a space which would ordinarily be enough only for six letters. Also, only 9 leads are needed for making connection to all of the segments.
Although the appearance of the various combinations of letters corresponding to the various days of the week can be discerned by study of FIG. 1, the way in which the days of the week will be represented when unactivated segments are not visible is shown in FIG. 2. FIG. 2 also shows the relative locations of the various pairs of letters on a strip such as would be allocated for such representation on the face of a timepiece. Furthermore, since groups of segments 11, 12 and 13 function quite independently of each other, these groups could be arranged in any of the six possible permutations without affecting the operability and mode of operation of the system.
Similar arrangements are readily made where the days of the week are to be indicated in French, German or Spanish.
The arrangement of segments suitable for showing the days of the week in French is shown in FIG. 3. Here segment 34 consists of portions 34a and 34b connected by conductive strip 34c. Similarly, segment 38 consists of the two portions 38a and 38b connected by the conductive strip 38c. The total number of leads necessary to make connection to all of the segments is 10. As before, the appearance of the initial letters of each day of the week can be discerned from FIG. 3, but, for convenience, the appearance of the various combinations is shown in FIG. 4. As before, the combinations consist of three groups which could be shifted around with respect to each other.
An arrangement of segments suitable for showing the days of the week in German is shown in FIG. 5. Again, segment 43 consists of portions 43a and 43b connected by strip conductor 43c, segment 45 consists of portions 45a and 45b connected by strip conductor 45c and segment 48 consists of portions 48a and 48b connected by strip conductor 48c. It will be noted that there is a gap given the reference numeral 42g in the upper portion of segment 42. The purpose of this gap is to permit traversal therethrough of the strip conductors (not shown) which are used to activate segments 43 and 44 which are disposed within segment 42. The total number of leads necessary for activating the segments is nine.
As before, the appearance of the initial two letters of each day of the week is shown in FIG. 6.
An arrangement of segments suitable for showing the initial letters of the days of the week in Spanish is shown in FIG. 7. Segment 50 consists of portions 50a and 50b connected by conductive strip lead 50c, segment 55 consists of portions 55a and 55b connected by conductive strip 55c and segment 58 consists of 58a, 58b and 58c connected by conductive strips 58d and 58e. In this case only eight conductive leads are necessary for activating the segments.
Once more, the appearance of the initial two letters of each day of the week are shown in a separate Figure, namely FIG. 8.
It will be noted that the maximum number of segments necessary for showing the initial two letters of the day of the week in any of the languages exemplified was ten.
It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above article without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

FIG. 8 shows how the first two letters of each day of the week appear when appropriate segments as in FIG. 7 are selectively activated.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In order to be able to represent the initial two letters of all seven days of the week in English, it is necessary that the capital letters S, M, T, W and F be presented, and that the lower case letters u, o, e, h, r and a be represented. Furthermore, as is evident, appropriate letters must be contiguous so that the combinations Su, Mo, Tu, We, Th, Fr and Sa must be shown with the lower case letter following immediately after the capital. As aforenoted, to place all seven pairs of letters separately on a dial would require the occupation of too great a space. Reduction in space is achieved by dividing a number of the letters into segments and arranging for the use of at least one segment and preferably a plurality of segments in more than one letter or combination of letters.
A particularly good solution to the problem using the above principle is shown in FIG. 1. Group 11 consists of segments which overall has a shape which is close to "Tu, Fr." The group is divided into the segments 21, 22, 23 and 24 in which segment 23 is h-shaped. The shape is achieved by reason of the fact that segment 23 actually consists of two portions 23a and 23b which are electrically connected by lead 23c. To display the combination "Tu", segments 21 and 22 are activated. To display the combination "Th", segments 22 and 23 are activated. For the combination "Fr", segments 23 and 24 are actuated. It will be noted that segment 24 consists of two portions 24a and 24b connected by the electrical lead 24c. As can be seen from this description, group 11 occupies approximately the space which would normally be utilized for presenting only three letters. However, group 11, by selective activation of the proper segments, actually achieves the feat of presenting six letters (two of which are the same) in the space ordinarily needed for the presentation of three letters.
Group 12 is divided into three sets of segments, 25, 26 and 27. Each of the segments is further divided as can be seen from FIG. 1. For displaying "Mo", segments 25 25a 26 and 26a are activated. For displaying "We", segments 26 26a 27 and 27a are activated. Thus, sections 25, 26 and 27 together with 25a, 26a and 27a display four letters in the space normally occuplied by two.
Finally, group 13 consists of segments 28 and 29. For the display of Su, only segment 28, which is divided into two portions electrically connected, is activated. For the display of Sa, both segments 28 and 29 are activated. In the case of group 13, four letters (two of which are identical) are displayed in the space normally used by two.
It will be noted that the number of leads from the segments to a power source (not shown) needed is only nine, whereas fourteen leads would be needed if the letters were unsegmented and were placed side by side. Also, a plurality of segments are used in more than one letter.

The arrangement of segments suitable for showing the days of the week in French is shown in FIG. 3. Here segment 34 consists of portions 34a and 34b connected by conductive strip 34c.

An arrangement of segments suitable for showing the initial letters of the days of the week in Spanish is shown in FIG. 7. Segment 50 consists of portions 50a and 50b connected by conductive strip lead 50c, segment 55 consists of portions 55a and 55b connected by conductive strip 55c and segment 58 consists of 58a, 58b and 58c connected by conductive strips 58d and 58e. In this case only eight conductive leads are necessary for activating the segments.
Once more, the appearance of the initial two letters of each day of the week are shown in a separate Figure, namely FIG. 8.
