Definitions

  • the present invention relates to an electronic timepiece providing time information by means of a dynamic display intended to visualize, in a symbolic and attractive manner, the flow of given time intervals and / or the impending d 'an event related to one or more functions, or to the operation of said timepiece.
  • the invention relates to a timepiece of the aforementioned type in which the dynamic display is constituted by a set of discrete elements forming a pattern, said elements being activated selectively by means of a microprocessor or a circuit.
  • logic comprising means for managing the dynamic display and receiving at least one time and / or operating signal, said microprocessor or logic circuit making it possible both to impose the rate of increase or decrease in the number of elements activated and carrying out at each variation a random or pseudo-random selection of the elements to be activated among all of the elements of the pattern, so as to reveal or progressively mask said pattern during the passage of a given time interval, or near a deadline in relation to the functions or operation of said timepiece.
  • the visualization of the correct functioning can be carried out, for example by placing a motif (character, flower, sun, etc.) on the second hand, or by beating the second to a figurine, or by driving, by the seconds axis, a disc placed under a dial provided with one or more counters revealing decorations carried by the disc.
  • a motif character, flower, sun, etc.
  • the patent US 372 074 describes for example an embodiment in which a disc is divided into six sectors each comprising a different figurine which appears in a window of the dial every 15 seconds.
  • Patent BE 772 949 describes for example a liquid crystal display device, of the pseudo-analog type, in which the time indication is given. by changing the activation of luminous segments appearing on the dial and representing the hour and minute hands and by flashing another mark, such as a central disc to beat the second.
  • Patent CH 665 078 describes for example a timepiece with special aesthetic effects which makes it possible to discover a decoration in a clear and comprehensible manner only every 217 days by cooperation of two discs.
  • the display by means of a liquid crystal cell also made it possible to propose solutions making it possible to visualize the flow of a given time interval, or to announce the imminence of a given event.
  • Such a display also makes it possible to view the beat of the second at the same time and to produce aesthetic effects.
  • Patent GB 2 050 008 describes for example an electronic watch with alphanumeric display making it possible to gradually show the activated function from its activation to its realization (for example alarm time).
  • US Patent 4,397,595 describes, in addition to a conventional digital display with seven segments, a figurine whose eyes beat the second in 10 different, but repetitive modes.
  • patent GB 2 119 994 describes two displays, the first being a classic alphanumeric display and the second being constituted by a figurine constituted by different elements connected, in six selectable modes, to the segments of the classic display, and activated by together with these to create a repetitive animation of the figurine.
  • timepieces comprising at least one liquid crystal display
  • it is observed that, whatever the appeal of the visualization effect obtained, it always presents a repetitive character, at the regular rhythm of the time which elapses. In other words, after a certain time, the user will necessarily be able to predict how the animation of his watch will evolve, and what the final pattern will be.
  • the present invention is, on the contrary, intended to break with the monotony generated by the repetitive and predictable nature of the animations known from the prior art.
  • the invention relates to a timepiece making it possible to visualize in a symbolic, dynamic and attractive way the flow of a given time interval, or the proximity of a deadline in relation to the functions or the operation.
  • this timepiece being characterized in that it includes a dynamic display in the form of a pattern consisting of a set of discrete elements, the number of which is activated at a given instant is representative of the event in progress, but in which the selection of said activated elements is carried out randomly or pseudo-randomly among all the available elements of the pattern, each time an additional element is activated.
  • the activatable elements constituting the pattern may be any, but according to a preferred embodiment, with respect to which the invention will be described below in more detail, the activatable elements are constituted by the electrodes of a liquid crystal cell, shaped in pieces of a puzzle, the pattern consisting of a decoration placed at the rear of the cell, said decoration being progressively revealed or masked, depending on the activation of the pieces of said puzzle.
  • the same timepiece also includes a time display of the traditional analog or digital type.
  • This second traditional display is preferably placed on the same dial as the dynamic display according to the invention.
  • Another object of the invention is a timepiece which makes it possible to visualize several events at the same time in a symbolic, dynamic and attractive way, such as the beat of the second and the passage of time.
  • Another object of the invention is a timepiece of which a dynamic display makes it possible to gradually reveal or mask an entire pattern according to different animations at each cycle.
  • Another object of the invention is a timepiece whose individual elements of the pattern do not individually deliver any intelligible information, whether graphic or alphanumeric.
  • the timepiece according to the invention comprises a display, consisting of n parts (P1, P2, ..., P j , ... P n ) of a puzzle allowing to visualize in a symbolic, dynamic and attractive way the flow of a time interval T and / or to announce the expiration of an event E.
  • the time interval T can be arbitrary, but it will advantageously represent an entire time measurement interval such as the minute, hour, day, week, month, year or multiples of these time intervals.
  • the event E is representative either of a function of the timepiece, such as the alarm time or the expiration of a predetermined duration, or of its operation, such as the end of life of the battery. .
  • n a number any integer, preferably between 2 and 60.
  • such a variant makes it possible for example to visualize at the same time the beat of the second by changing the selection of the activated parts, but also the imminence of another event E, such as an alarm time or end of battery life, by flashing of the x parts activated at time T x .
  • the time interval T can be constituted by the sum of several intervals T i .
  • Each interval T i is then characterized by its own elementary interval t i , corresponding to the activation of a number n i of puzzle pieces, said pieces being chosen from among the n pieces available.
  • this can be expressed by the following relationships:
  • the random or pseudo-random selection of the n i pieces of the puzzle in the time interval T i is carried out by the same microprocessor, or the same logic circuit.
  • the number n of puzzle pieces is a construction element that cannot be changed.
  • the microprocessor or the logic circuit it is possible to obtain, with the same timepiece, different dynamic and attractive effects by acting either on the value of T (hours, half hour, quarter of an hour, minute), or on the values T i and n i , for given values of T and n, these selections being made for example by means of external control members.
  • This first example corresponds to a first embodiment of a dynamic display according to the invention.
  • FIG. 1 represents a watch with a circular dial 4, the lower half of which is formed by a traditional time display 1, while the upper half comprises the pattern 5 of a display 2 consisting of the pieces Pj of a puzzle dynamic.
  • the dynamic puzzle has an activation cycle of 1 hour and includes 12 pieces, all of which are activated in Figure 1, and thus revealing a decoration 3 entirely (see Figure 2).
  • the watch has three buttons 34, 35 and 36 located on one side of the case, these buttons being intended to manage the standard functions (setting the time, setting the alarm, memorizing a predetermined duration, etc.) and to possibly change the dynamic animation mode of the puzzle.
  • connection strip 23 and the counter-electrode 25 are connected to a microprocessor, or to a logic circuit controlling the display 2.
  • the counter-electrode can be produced without any structuring, that is to say by not comprising no non-conductive portions 26.
  • the central parts when activated, appear connected by a thin cord to an edge of the cell.
  • it is possible to use other types of display cells for example a cell known as a "Heilmeier cell”.
  • the circuit of a watch comprises a conventional timepiece circuit 40 associated with a traditional display means 1, of analog or digital type, and further comprising a microprocessor or a logic circuit 50 associated with the liquid crystal display 2 according to the invention.
  • External control members 34, 35, 36 make it possible to control either the timekeeper circuit 40 or the microprocessor or logic circuit 50.
  • the control member 34 is for example assigned to the timekeeper circuit 40, and the member control 35 to this circuit 40 and to the microprocessor or logic circuit 50 and the control member 56 is assigned to the only microprocessor or logic circuit 50.
  • the timepiece circuit 40 essentially comprises an oscillator constituted by a quartz resonator 42 and a maintenance circuit 41, a division chain 43, 44, 45 and a management circuit 46 for the usual functions associated with a traditional display.
  • the oscillator delivers at its output a time base or reference signal S0, having for example a frequency of 32 768 Hz.
  • a first chain of dividers 43 receives the signal S0 and delivers at its output a signal S1 having a frequency of 1 Hz.
  • This signal S1 is then divided by 60 by a divider 44 which provides at its output a signal S2 formed by one pulse per minute.
  • Another divider by 60 referenced 45 receives the signal S2 and finally provides at its output a signal S3 formed by one pulse per hour.
  • management circuit 46 and the microprocessor 50 have been shown separately for a better understanding of the invention, but it is obvious that these two elements 46 and 50 could be combined in a unique microprocessor comprising both a program for managing a traditional display and a program for randomly selecting x data from n available data.
  • the separate element 50 corresponds to a logic circuit
  • Such a circuit includes a first part 51 which generates a counting pulse CNT from a signal S x , which can be one of the signals S0, S1, S2 or S3, or even a signal extracted from the divider 43.
  • the signal S2 is preferably used.
  • This CNT pulse activates an oscillator 52 which rotates a Johnson counter 53 with n outputs.
  • Parts 51, 52 and 53 together constitute a random generator in which only one of the n outputs of circuit 53 is activated at a time when the CNT pulse is completed.
  • This pulse CNT will also signal to a drive circuit 55, conventionally interposed before display 2, to store the value obtained and to display it on display 2, that is to say to activate the corresponding piece P j ; an additional logic stage 54, arranged between the elements 53 and 55 makes it possible to store more than one random selection so as to display more than one room at a time.
  • Figures 4a to 4d illustrate the operation of a watch according to this first example.
  • the visual aspect of the dynamic puzzle is changed every 5 minutes both by activating an additional piece and by a new random selection of the activated pieces.
  • FIG. 4a represents the appearance of the puzzle as soon as the random selection program is started and during the first 5 minutes (first elementary time interval t, designated t1): a single piece of the puzzle is activated.
  • FIG. 4b represents the appearance of the 15th to the 20th minute (t4): four parts are activated without necessarily finding the three parts activated in the preceding time interval t3.
  • Figure 4c shows the appearance of the 35th to the 40th minute (t8): eight pieces are activated.
  • Figure 4d shows the aspect of the puzzle from the 50th to the 55th minute (t11): eleven pieces are activated.
  • the appearance of the puzzle in the time interval t12 is that shown in FIG. 1, in which all the pieces are activated, thus revealing the decoration 3 in its entirety.
  • the same cycle will be reproduced in the following interval T ′, without necessarily having for each elementary time interval (t1 to t12) identical, the same activated parts among the n available parts, as shown in FIGS. 4a ', 4b', 4c 'and 4d', corresponding respectively to the elementary time intervals t'1, t'4, t'8 and t'11.
  • the microprocessor 50 uses only the signal S2 as the time base signal.
  • a change of time base which would give the time interval T a different value, for example by means of the control button 36, would make it possible to have a faster animation, for example over 1 minute (use signal S1) or slower, for example over 12 or 24 hours (use of signal S3).
  • this result can be obtained by flashing at the rate of the second of at least one part activated at this given instant.
  • a change from one mode to another, for example, for two successive periods T and T ′ is possible either randomly or by means of the control button 36.
  • the "flashing" mode, or the "displacement” mode, described in example 2 in order to have a permanent visual indication of the beat of the second, can be used sporadically for a predetermined duration preceding or following the expiration of a event E.
  • This event is for example an alarm time programmed simultaneously in the management unit 46 and in the microprocessor or the logic circuit 50 by means of the control member 35. It is also possible to use these two visual indications in the same watch, to visualize two events E1 and E2.
  • the current indication modes such as a ring for the alarm time or a counter index for the end of battery life.
  • this embodiment comprises a watch having a traditional analog display by hands, and a dynamic display constituted by a puzzle of 20 pieces occupying the entire dial.
  • the change of state of the dynamic display takes place every three minutes.
  • the rate of appearance of a new part will therefore be faster, but all the possibilities and variants described or suggested in Examples 1 to 3 are applicable.
  • hourglass type is meant a visualization of the flow of a time interval T, giving the impression of an acceleration, as the time period T approaches.
  • This embodiment is described with reference to FIG.
  • the number of activated parts increases by one unit every 6 min during the T1 period, then every 3 min during the T2 period, then every 2 min during the T3 period, and finally every 1 min during the period T4, thus creating an effect of acceleration of the movement as the expiration of the hour arrives.
  • this embodiment lends itself to an infinity of variants by acting either on the programming of the microprocessor, or on the construction of the cell, or on the characteristics T, T i , n and n i , it being recalled that n (respectively n i ) is not necessarily an integer divisor of T respectively T i ), as will appear moreover in the following example. It is also quite certain that the possibilities offered by the preceding examples are applicable in whole or in part to the present example.
  • the image of the puzzle also includes a text whose intelligibility is not necessarily always possible, except when all the pieces of the puzzle are activated.
  • Example 7 Dynamic puzzle display before at least two separately addressable areas
  • the n pieces are fictitiously divided into groups of n i pieces, but these n i pieces are randomly chosen from all the n pieces of the puzzle.
  • the n pieces of the puzzle of the liquid crystal display are, on the contrary, divided into groups of n i isolated pieces.
  • Each group of n i parts can be addressed separately, according to one or more modes described in the previous examples, and corresponds to a time interval T i having a different value.
  • FIG. 7 represents a watch whose rectangular liquid crystal dial includes a zone 1 reserved for the traditional time display and a zone 2 constituted by a dynamic puzzle of 19 pieces distributed in two zones respectively comprising 12 regular shaped pieces (zone 2a) and 7 irregular shaped pieces (zone 2b).
  • the display in each of these zones 2a and 2b is controlled by different programs of the microprocessor, according to any of the modes described in the previous examples.
  • Such a watch would then make it possible to visualize the flow of the day hour by hour and that of the week, day by day.
