    Detailed Description of the Preferred Embodiments
  • The invention thus relates to a universal moon phase display device 10 for a watch 1000.
  • This device 10 comprises first means 1 for calculating or receiving the current date, and second means 2 for receiving a geolocation signal.
  • The device 10 conventionally comprises at least a first display 6, which comprises at least one normal moon representation 11. The device 10 comprises first drive means 7 for driving this first display 6.
  • According to the invention, this device 10 comprises third means 3 for calculating or receiving a lunar calendar 4, which comprises at least the correlation between the date and the moon phase.
  • This device 10 also comprises position calculation means 5, which are arranged to transform the moon phase of the day into a first value of angular position aL of the first display 6, which is including but not limited to a moon disk.
  • These position calculation means 5 are further arranged to determine the northern or southern hemisphere in which the device 10 is located, to control the direction of rotation of the first drive means 7 to drive the first display 6, in a first sense in the northern hemisphere or in a second opposite direction in the southern hemisphere.
  • The Figures 3N and 3S illustrate respectively the moon's direction of movement in the northern hemisphere and in the southern hemisphere.
  • The Figures 4N and 4S similarly illustrate the distinct representations of the moon, at the same time, in these two hemispheres.
  • More particularly, the first drive means 7 comprise at least a first electric motor, which is arranged to rotate in both directions of rotation, so as to drive the first display 6 in a first direction between a start of lunation position and an end of lunation position so as to perform a complete race in a lunar month, with a limited angular stroke and strictly less than 360 °, and so as to drive the first display 6, at the end of a lunation, in a second opposite direction in the first direction between the end of lunation position and the start of lunation position in a substantially instantaneous fast retrograde motion.
  • The figure 5 illustrates a first display 6 which has a unique moon representation which is the normal moon representation 11.
  • This particular arrangement, with a first electric motor arranged to rotate in both directions of rotation, also makes it possible to use the same first display 6 which comprises several representations of the moon, such as that of the figure 7 , which has a normal moon representation 11 and a red moon representation 12, which are diametrically opposed in the particular example of this figure 7 . To sink to display the element in opposition to the appropriate representation of the moon, the first display 6 to go back and forth, which allow the two directions of rotation of the first electric motor.
  • In a particular variant, the lunar calendar 4 includes the dates of total lunar eclipses and red moon days, and the first display 6 then comprises, according to distinct angular positions, at least one normal moon representation 11 which is displayed by default and at least one 12. The position calculating means 5 are arranged to control an appropriate rotation of the first driving means 7 to substitute a red moon representation 12 for a normal moon representation 11, when the current date corresponds to a red moon date. For example, the normal moon representation 11 is diametrically opposed to the red moon representation 12 on the same moon disk, and the position calculation means 5 control a rotation offset by 180 ° in the case of a red moon, compared to calculated for a normal moon. The red moon is predictable, after total lunar eclipses and after the full April moon, and the lunar calendar 4 can easily handle the dates. As eclipses and red moons are predictable events in the long run, it does not. It is not essential to calculate the position of the day in the lunar month, if it was done beforehand once and for all. To determine them one can resort, or to an external resource, or to an internal memory.
  • In a particular variant, the device 10 comprises a second display 8, which comprises at least one horizon representation with respect to which is movable the first display 6. More particularly, this second display 8 constitutes a cache overlay of a part of the first display 6. This second display 8 may constitute a conventional static mask. More particularly, this second display 8 is movable at least in a concentric rotation with the first display 6, to allow a realistic rendering of the moon phase. More particularly still, this second display 8 is mobile at least in a translation, in particular but not limitatively radial, with respect to the first display 6.
  • The Figures 3 and 4 show classic profiles of the second display 8, in use on the usual moon phases for temperate regions. The figure 6 illustrates another variant of representation. Indeed, the tropical, equatorial and polar regions require caches of different shapes to better materialize the real appearance of the moon in these regions, during its different phases, as shown in particular by the figures 16 and 17 designed for the tropics. The figure 18 illustrates an example of a mask on a second display 8 designed to be maneuvered in translation to best adapt to a range of predefined latitudes, and successively comprises the mask of figures 3 and4, and those of figures 16 and 17 . The figure 19 illustrates another example of a combined mask which successively comprises the mask of Figures 6 and 3 .
  • The position calculating means 5 can advantageously use the second means 2 for receiving a geolocation signal to determine the latitude of the place. Using this setting may allow a display with a much more realistic rendering of the moon's appearance. This realistic display can be obtained with the use, for certain latitudes, of a second particular display 8, as visible on the figures 16 or 17 where this second display 8 is stationary after its introduction in superposition with the first display 6 which alone is mobile, especially in rotation.
  • In a particular variant, the second display 8 is movable relative to the first display 6, in rotation or / and in translation. More particularly, the second display 8 is mobile at least in a radial translation with respect to the first display 6.
  • Thus, in an advantageous variant, the position calculating means 5 are designed to calculate the latitude of the place where the device 10 is located, and to control second drive means 9 that the device 10 comprises for driving the second display 8 compared to the first display 6.
  • The figure 16 , numbered in sequence from 16.1 to 16.12, and 17, numbered in sequence from 17.1 to 17.12, illustrate two nonlimiting examples of particular configurations of the second display 8.
  • Preferably, the device 10 thus comprises an electromechanical mechanism for moving the horizon. In a particularly simple embodiment, a rack is driven using a pinion coupled to the motor. One can also use another principle with only pivoting (without translation), with a simple pivoting of the horizon, or with a pantograph type system.
  • The taking into account of the latitude for a realistic display, with a mobile horizon at least in rotation with respect to the moon disk, but also in a particular variant in radial translation with respect to the axis of the moon disk, makes it possible to offer a feature that is generally not well handled in moon phase displays.
  • In a particular variant, the first drive means 7 comprise at least a first electric motor which is arranged to rotate in a single direction of rotation. And the position calculation means 5 are then arranged for controlling the speed of the first driving means 7, so as to drive the first display 6 at a first speed, in a first race where the at least one normal moon representation 11 is visible, between a starting position of lunation and an end of lunation position so as to perform a complete race in a lunar month, with a limited angular stroke and strictly less than 360 °, and so as to drive the first display 6, at the end of a lunation, at a second speed at least thirty times greater than the first speed, in a second race where the at least one normal moon representation 11 is not visible, between the end position of the lunation and the starting position of a lunation in a movement of shorter duration or equal to one day.
  • The figure 8 illustrates such a configuration, with a first display 6 having a single normal moon representation 11, and which always turns in the same direction. In the northern hemisphere, as shown, the normal moon representation 11 passes from the cover A to the cover B of the second display 8, remains hidden under the part B at the end of the lunation, then goes back directly under the cover A to start a new one period. In the southern hemisphere, it is the opposite: the normal moon 11 representation goes from the cover B to the cover A of the second display 8, remains hidden under the part A at the end of the lunation, then goes back directly under the cover B to start a new period.
  • In a variant, the first calculation means 1 or the reception of the current date are means for receiving a signal transmitted by a satellite or by a mobile telephone device 100 arranged to be worn by the user of the shows 1000.
  • In a variant, the second means 2 for receiving a geolocation and / or indication signal from the terrestrial terrestrial hemisphere are means for receiving a signal transmitted by a satellite or by a mobile telephone device 100 arranged to be worn by the user of the watch 100.
  • In a variant, the third means 3 for computing or receiving a lunar calendar 4 are means for receiving a signal transmitted by a satellite or by a mobile telephone device 100 arranged to be worn by the user of the shows 1000.
  • Such a mobile telephone apparatus 100 may consist of a "smartphone" or the like, with which the watch 1000 may exchange information, without necessarily involving user action.
  • More particularly, a method "WOP watch optical programming" transmission between a mobile phone device 100 and a watch 1000 makes it possible to transmit the location of the user to the watch, and the modification of the display of moon phases , or other displays, such as sunrise and sunset, or tides. Other protocols such as "Bluetooth Low Energy" or "NFC" can be used to send this information to the watch.
  • The location of the user is known to the mobile telephone apparatus 100 by different techniques:
    • "GPS" which gives longitude and latitude;
    • presence in a country that is determined by both the "GPS" and the cellular network to which the phone is connected.
  • The mobile telephone apparatus 100 can transmit this information in various formats:
    • latitude: positive in the northern hemisphere - negative in the southern hemisphere;
    • some bits coding (2 bits): hemisphere North - South - Ecuador - Pole
    • the country code used to determine if DST or Daylignt Saving Time is to be done.
  • For the calculation of moon phases, the "WOP" protocol transmits the date, so that the moon disk can indicate the correct moon phase. The moon period is 29.53 days, it is customary to describe the appearance of the moon in lunar days numbered from 1 to 29, the lunar cycle is usually divided into 8 phases, each lasting about 88 hours.
  • These phases are, in the northern hemisphere and in this order, visible on the figure 10 : new moon 10.1, evening croissant 10.2, first quarter 10.3, increasing gibbous moon 10.4, full moon 10.5, waning gibbous moon 10.6, last quarter 10.7, morning crescent 10.8.
  • While in the southern hemisphere, on the same figure 10 In this order we have: Evening Crescent 10.8, First Ward 10.7, Increasing Gibbous Moon 10.6, Full Moon 10.5, Waxing Gibbous Moon 10.4, Last Ward 10.3, Morning Crescent 10.2, New Moon 10.1.
  • To calculate the moon day at a certain date, it is necessary to know the moon day on a given date, to calculate the number of days until the date considered, and to perform a division modulo 29,53, of which the result represents the moon agenda.
  • The invention also relates to a watch 1000 comprising at least one such device 10.
  • The invention also relates to a portable assembly 2000, including such a watch 1000, and a mobile telephone apparatus 100 arranged to provide a signal or information geolocation and / or indication of the terrestrial hemisphere of the place, and / or of date to a device 10 that includes the watch 1000.
  • The figure 11 illustrates a non-limiting example of a control algorithm for the display of moon phases. At the level of the watch 1000, the function 110 is the management of the time of the watch, in 111 occurs the test performed at midnight. The calculation of the lunar day is done in 112 according to the elements received from the mobile telephone apparatus 100: 116 "GPS" location or the like; 117 recourse to a memory or a server for the determination of total lunar eclipses and red moons; 118 transfer to the watch. Step 113 is that of the calculation of the moon phase, taking into account the date and the location, and in particular the hemisphere, supplemented if necessary by the occurrence at 114 of eclipse or moon red, for display in 115 of the moon phase, with the appropriate moon type (normal moon or red moon).
  • The figure 12 illustrates another nonlimiting example of an algorithm: 120 search for the hemisphere; 121 use of geolocation and / or indication of the terrestrial hemisphere of the place; 123 determination of the hemisphere; 124 direction of rotation of the motor of the first display; 124 taking into account the latitude for the orientation of the moon at 125; searching for the date in 126 with internal direct calculation or external recourse in 1260, to determine the date in 127; search of the lunar calendar in 128; internal, or external recourse in 1280, to determine in 129 the angle of rotation aL imposed on the motor 7.
  • The figure 13 illustrates a red-moon management algorithm, with in 130 looking for a red moon, internally or externally in 1300, to determine at 131 the appearance of the moon, and choose, at 132, to maintain the angular control of the motor in 133 in case of a white moon, or to print an angular phase shift in 134.
  • The figure 14 illustrates a translation algorithm of the second display 8 with respect to the first display 6, after the determination of the orientation and the latitude, in 140 calculation of the offset, 141 rotational coupling, and relative translation.
  • The figure 15 illustrates a speed management algorithm for an accelerated display: in 150 end of lunation test, in 151 acceleration of the engine in 152 resumption of normal speed.
  • In sum, an algorithm can accurately predict the appearance of the phase of the moon according to the date. Geolocation and / or indication of the terrestrial hemisphere of the place makes it possible to modify the appearance and direction of rotation of the first display 6, in particular a moon disk.
  • The connection between a mobile phone device 100 and a watch 1000 allows automatic adjustment, without user intervention.
  • The invention offers different advantages:
    • the display of the moon phase is just in relation to the date of the day and the hemisphere of the place where it is mounted;
    • the setting is simplified;
    • it is enough for a disc with a single moon, in the simple variant where one does not manage the display of the red moon;
    • the variant where we manage the display of the red moon only requires the adaptation of the moon disk with the addition of a representation of the red moon;
    • the use of location latitude transmitted by geolocation makes it possible to refine the moon phase displays in the equatorial, tropical and polar regions, which was possible until now only with rare Haute Horlogerie watches. very high cost,
    • the display of the tides can advantageously coupled with that of the moons. The link with an external resource is particularly interesting since it allows to take into account the specificities of the coasts. It is possible either to transfer the pre-calculated hours of high, low, and tidal tides, or to transmit the values for the current day, and to recalculate the future values using a polynomial of which one sends the coefficients to the watch;
    • the taking into account of a summer time correction can be made by the connection between a mobile phone device and the watch, and is necessary in the case of management of tide schedule.
