Definitions
- Date display device in particular for an electronic timepiece
- Electronic timepieces are known in particular comprising the display of the time, this in several time zones, some also comprising the mechanical or liquid crystal display of cyclical phenomena such as the movement of the tides or the phases of the moon; timepieces are also known comprising a calendar with alphanumeric optoelectronic display enabling the date to be read which can be automatically corrected as a function of the number of days in each month.
- this calendar is only given in one system, the Gregorian system for example. It is therefore not possible, without going through complex conversion tables, to find the same date in a different calendar system, such as, for example, the republican calendar or the Muslim calendar.
- the object of the present invention is to realize a date display device, in particular for an electronic timepiece which overcomes the inconvenience mentioned above.
- the device is characterized in that it is arranged in order to distribute and display indications of corresponding dates in at least two calendars of different systems, the display of at least one of these indications being made in a language intelligible to the user, that is to say in the alphanumeric characters specific to the language of the user, this in opto-electronic alphanumeric form.
- FIG. 1 is an elevational view of a ca- from an embodiment of the object of the invention displaying a date in the republican calendar
- fig. 2 is a partial elevation view of a dial of the same embodiment of the invention displaying the same date in a calendar of a different system, in this case the calendar customary in the Western world and which then serves as a calendar of reference
- fig. 3 is a block diagram of the electronics associated with an embodiment of the object of the invention
- FIG. 4 is a block diagram of the electronics associated with another embodiment of 1 • object of 1 • invention.
- FIG. 1 and 2 show the parent characters on the dial of a timepiece according to an embodiment of the object of the invention.
- this dial 1 there is a date display system 2 extending over two lines 3 and 4.
- On the first line are the number of the day as well as the name of the day; in this example given for a republican system calendar, the display indicates "7 vendage", while on the second line 4 is the figure for the year, here "CXCVII".
- This information is given in its original characters, in alphanumeric characters; here, for example, the year is in Roman numerals.
- This information can be translated into language intelligible to the user, for example by the automatic and alternating appearance of the year in Arabic numerals, here "197".
- the example shown in * figs 1 and 2 corresponds to an embodiment of 1 • object of the invention, a display system of the Gregorian calendar and the republican calendar; in other forms' of exé ⁇ execution, it is possible to have such a afficha ⁇ age the Gregorian calendar and the Islamic calendar or Jewish calendar or the Japanese calendar, etc., the combination of the display possible ⁇ e two or more of these calendars being any.
- the display is made in alphanumeric characters specific to the language of the user, this generally also requiring a point display system, the size of the matrix of which depends on the type of alphabet used.
- the number of connections to the integrated circuit can be reduced by using the multiple ⁇ xing technique and, if this proves to be insufficient, the scrolling displays can be called up; in this case, it is easy to complete the date by displaying the name of the day, for example.
- the dial can be completed by a calendar aperture 27 with mechanical calendar.
- Fig. 2 shows the same dial displaying the same date as shown in FIG. 1, but in a different system calendar, namely, in this case, the usual Gregorian calendar, the date of September 28, 1988 corresponding to the date of the 7th Vendemiaire CXCVII.
- the passage of a date from one calendar system to another system is effected by the action on a push button, not shown in FIGS. 1 and 2.
- Each of the dates can be presented in a fixed manner + or one can also envisage the automatic passage from one calendar to the other by acting as previously on a pusher; in this case we would have an alternating display of dates.
- the change of day at midnight of the calendars can be synchronized with the passage at mid-night of the time of the analog movement of a timepiece, or not; in the latter case, the calendar has its own internal clock with digital display which is manually synchronized by a push button with the analog movement.
- calendars are based on the technology of digital integrated circuits and segment or dot displays.
- Fig. 3 is a block diagram of 1 • electronic control of a first form of execution of the object of the invention in which the calendars are stored in memory over a certain number of years , depending on the memory capacity. We are then in the presence of a simple reading of the memory, the scrolling of which is controlled by the internal time base.
- a quartz oscillator 5 used for the manufacture of a stable sinusoidal signal
- a divider block 6 used to lower the frequency of the pulses, the sinusoid being transformed into a square signal by means of a trigger
- an amplifier 8 and a motor 9 which drives a roua ⁇ ge distributing the information to the needles there.
- the crown 10 fixed on a control rod makes it possible to adjust the position of the needles.
- the - 5 - seems 8, 9, 10, 11, generally designated by the reference 7, is optional and that it only applies in the case of a timepiece. This set is suppressed when dealing with an electronic calendar only.
- the lower branch of the block diagram includes the memory calendars 12, 13,, 14, a sequencer 15 which receives its commands from the keys A, .B and C and which can be designed in two different ways, namely with recorded program , according to the read-only memory (ROM) technique, which has the advantage of miniaturization, or else with a wired circuit.
- This sequencer selects the memories, that is to say the calendars to be read, and it transmits the information collected to the multiplexer for LCD 16 which displays the information on the display 17.
- the read only memories are only read and contain , in binary form, the alphanumeric data of each calendar.
- 1st press setting mode (for example flashing) 2nd press: reading mode
- Function push-button B 1st case: reading mode: switching from one calendar to the other 2nd case: setting mode:
- Increment push-button C
- the hour, minute and possibly second setting function is necessary when dealing with a timepiece with analog movement in which there is no synchronization between the analog movement and the calendar. Likewise, it is necessary in the case of a purely electronic calendar. However, it is not necessary for a timepiece in which there is a synchronization, for example based on the train of the analog part of the calendar. In this case, a gear train will cause the calendar to switch every 24 hours, by controlling a contact.
- Fig. 4 is a block diagram of the electronic control of another embodiment of the object of the invention in which the calendars are linked together by a calculation algorithm; it is then possible to add additional functions controlled by external pushers, such as for example: - calculation of a date of the past or of the future known in a calendar, in the other calendar (s), - calculation of durations elapsed between two dates, etc.
- a quartz oscillator 5 which counts events (here pulses received from a division stage), an interrupt block 19 which, when a number of events or pulses fixed in advance has been reached gives an order to interrupt a function displayed on the microprocessor, for example automatic change from setting mode to reading mode in the event that, after pressing the setting mode key, no setting is made; a micro oscillator 23 processor (optional); an arithmetic and logic processor 20 which performs in its binary language the calculations necessary for the establishment of non-memorized calendars; a ROM or read-only memory 21 which contains a calendar or the basic cyclic data of the calendar or the calendar determination program; a RAM or random access memory 22 to which access is permitted from the outside (change of data, introduction of new data, etc.), this element being optional; an input / output member 24 which is an interface
- This function could, for example, be fulfilled by a prolonged pressure on the push-button B when the mode push-button A is in read mode.
- the display device according to the invention could also be designed so as to be coupled to a receiver to which the information to be displayed is transmitted remotely as the display progresses. or by loading for a given display period, for example an adjournment.
