Definitions

  • the present invention relates to a timepiece with analog display comprising means for processing one or more decimal numbers.
  • the invention relates to a timepiece which can display, essentially using hands, in particular hours and minutes, decimal numbers corresponding to a programmed period of time which must elapse until the activation of an alarm.
  • alarm is understood here broadly as the supply to the user of a particular message, whether in visual, audible or other form, to inform this user of the expiration of the programmed time.
  • the decimal number programmed in this room can represent a number of days until the expiration of a date, for example an appointment or a birthday.
  • the present invention therefore aims to provide an analog timepiece of a simple construction and handling, reliable and inexpensive, capable of processing, that is to say of displaying, memorizing and manage one or more decimal numbers corresponding to a programmed alarm time.
  • the invention also aims to provide a timepiece capable of displaying and processing decimal numbers in a clear, legible and intelligible manner to guarantee the user a manipulation of this piece which is easy and without risk of error .
  • the subject of the invention is a timepiece with analog display comprising means for processing at least one decimal number having several digits corresponding to a period of time which must elapse. until the activation of an alarm, characterized in that it comprises a first display system cooperating with a first hand to selectively indicate the order or weight of said figures, and a second display system cooperating with a second hand to indicate the value of the digit whose order or weight is indicated by the first hand.
  • the first display system is arranged in a first angular sector defined on said part, while the second display system is arranged in a second angular sector, complementary to the first.
  • the first display system comprises multiples of decimals which define the order or weight of said figures and which are inscribed between the positions 9H and 12H of said piece, the second display system comprising indications 0 to 9 combined with the indications 12H to 9H of a classic time display.
  • the first display system includes the indications 1, 10 and 100.
  • FIG. 1 therefore shows, in the form of a block diagram, a timepiece, for example a watch, constituting an embodiment of the present invention.
  • This timepiece is shaped to be able to process, that is to say to be able to at least display essentially analogically, using its hands, a corresponding composite decimal number programmed time to elapse until an alarm is activated.
  • the decimal numbers processed represents a number of days which is counted down ("count-down" operation according to the British name) until the expiration of a date, for example a date or a birthday.
  • this treated decimal number is programmed by the user, but it is understood that this invention also applies to a timepiece delivered with a decimal number preprogrammed by a supplier, without the possibility of modification, in order for example to provide an alarm at the end of an important date, in particular the passage to another century, a national holiday, or other.
  • the user is supplied, at the end of said date, alarm information in the form of an alphanumeric message, the intelligible composition of which is carried out by hands, in particular hours and minutes which will be described below.
  • alarm information in the form of an alphanumeric message, the intelligible composition of which is carried out by hands, in particular hours and minutes which will be described below.
  • this embodiment is particularly advantageous, the invention is not limited to this type of alarm which can be audible or formed by any other means.
  • the timepiece according to the invention comprises, in series, a quartz oscillator 2, a division chain 4 delivering a signal at 1 Hz, a position counter of a hand of the seconds, referenced 6, and a minute hand position counter, referenced 8.
  • the counters 6, 8 and 12 are counters by sixty, the operating mode of which is shown diagrammatically in FIG. 2.
  • pulses to be counted are supplied to the counters (arrow at the far left of the drawing). These successive pulses are counted by a binary register of at least six bits, which they increment. The status of this register can be read at any time (down arrow on the drawing). At each increment, the register is tested to see if the number it contains is equal to sixty. If this is the case, a pulse is emitted by the test circuit and this pulse causes the reset of the register.
  • the test circuit therefore constitutes a divider by sixty whose signal can be sent to another counter (right arrow on the drawing), which is the case of counters 6, 8 and 12.
  • This timepiece further includes a D-day counter which receives a signal every twelve hours from counter 12.
  • the D-day counter is a divider by 2 which provides a signal every twenty-four hours.
  • the counters 8 and 12 characterize, in normal operating mode, that is to say in the time supply mode, the position, defined according to sixty steps, of the minute and hour hands by report on the dial of the timepiece. Since the timepiece described here does not include a second hand, the second hand position counter only serves to provide a signal whose frequency makes it possible to increment the other counters 8 and 12 appropriately.
  • This timepiece is furthermore provided with two motors 18 and 20 which can be controlled independently by power circuits 14 and 16 respectively to drive the minute hand MN and the hour hand H respectively ( Figures 3 and 4).
  • the circuits 14 and 16 receive, in normal time mode, the pulses applied respectively to the inputs of the position counters of the minute hands 8 and hours 12.
  • Patent EP-0 393 606 in particular describes a timepiece movement comprising two motors capable of independently driving the minute hand and the hour hand.
  • the analog watch described here can also process decimal numbers, display them, store them and calculate them and then activate an alarm.
  • FIG. 1 The elements of FIG. 1 which will now be described, make it possible to provide these specific functions.
  • the timepiece comprises electronic control means 22 to enable it to fulfill various time display functions and a so-called "processing" function of one or more decimal numbers.
  • These electronic control means 22 comprise inputs MN and H for receiving the contents of the position counters of the minute hands 8 and hours 12, two activation inputs AN, EN and two input D+, D ⁇ for the data of displacement of the needles respectively forwards and backwards.
  • Patent EP-0 175 961 in particular describes a control rod associated with an interpretation circuit which can easily be adapted to be used with the timepiece presently described.
  • the electronic control means 22 also include two outputs Mmn and Mh for delivering pulses to the motors 18 and 20, and a control output C for managing the state of two switches 26, 28 arranged at the input of the power circuits 14 , 16 and arranged to transmit to them, either the pulses applied to the inputs of the position counters of the minute hand 8 and the hour hand 12 when the switches are in a first position referenced a , or the pulses delivered by electronic means control 22, when the switches are in a second position referenced b .
  • the electronic control means 22 can advantageously be produced in the form of an integrated circuit comprising a programmed microcontroller. Those skilled in the art will know, from the indications provided here, to carry out the programming of the microcontroller, so as to make it execute the functions described.
  • the electronic control means are inactive and the motors 18 and 20 receive the pulses applied to the inputs of the minute and hour hand counters 8 and 12 respectively.
  • timepiece according to the invention will be described below, and more particularly its display systems allowing the composition of decimal numbers.
  • the timepiece 1 conventionally comprises a box B, as well as a control rod T, the crown of which is seen here more particularly.
  • Timepiece 1 also includes a dial C on which is provided a conventional time display (not referenced) comprising indications 0 (in the conventional position 12 o'clock) to 11, written clockwise on the dial C .
  • the timepiece 1 comprises a first display system S1 cooperating with a first hand, here the hour hand H, for selectively indicating (see FIG. 5, steps E to J) the order or weight of the digits of the number to be processed, which in the example described with reference to FIG. 5, is the number 365.
  • the first display system S1 is formed in a first angular sector Sa1 defined on said part.
  • this first display system S1 comprises multiple decimals 1, 10 and 100 which define the order or weight of said digits of the number or numbers to be processed and which are entered between the positions 9H and 12H (replaced here by 0) of room 1, clockwise.
  • the indication 10 is confused with the indication 10H of the conventional time display, while the indication 1 is made between the indications 10H and 11H of this display.
  • the indication 100 is placed between the indications 9H and 10H of the classic time display
  • the timepiece 1 comprises a second display system S2 cooperating with a second hand, here the minute hand MN (see steps E to J of FIG. 5) to selectively indicate the values 0 to 9 of the digits of the decimal number to be processed.
  • the second display system S2 is formed in a second angular sector Sa2, complementary to the first S1.
  • the second display system S2 includes indications 0 to 9 which are respectively confused with the indications 12H (mark 0) to 9H of the conventional time display.
  • step E to J the second hand, and in particular the minute hand MN (conventionally represented as being the longest) can indicate the value (here 0 to 9) the number whose order or class is indicated by the first hand, among others the H hour hand.
  • the two display systems S1 and S2 are advantageously arranged on the dial, but in a nonlimiting manner, these can be arranged on a bezel, preferably fixed, of the box B, or on a ice, not shown.
  • the table or flowchart in Figure 5 includes eleven drawings or steps (referenced from A to K) each representing one of the different display functions that can be fulfilled by the hands of the watch according to the invention.
  • the arrows which connect the various stages A to K and the few indications which accompany them make it possible to understand how one actuates the control rod (here not referenced) to select one of the various display functions, in the various operating modes described.
  • the time correction function is activated by pulling the rod (step B).
  • the displacement towards the outside of the rod causes the emission by the interpretation circuit 24 (FIG. 1) of a signal towards the input EN of the electronic control means 22.
  • the reception of this signal by the electronic means of control 22 causes switches 26 and 28 to go into state b .
  • the electronic control means 22 emit a high signal on the reset line of the second position counter referenced 6 to keep it at zero so that it no longer provides the signal for incrementing the position counters of the 8 and 12 hour hands respectively.
  • the interpretation circuit 24 then sends pulses corresponding to the different rotational movements printed on the rod, by the user, to the inputs D+, D ⁇ of the electronic control means 22 which, in turn, emit pulses of command to increment or decrement the position counters of 8 and 12 hour hands and to simultaneously control the motors 18, 20 in order to move the hands.
  • the interpretation circuit 24 provides a deactivation signal to the electronic control means 22 which in turn provide a signal by their output C to put the switches 26, 28 in state a .
  • the signal on the reset line returns to zero and the second hand position counter 6 starts again.
  • the timepiece described here is designed to perform an additional so-called processing function.
  • FIG. 1 it includes two multiple registers 27 and 29 (FIG. 1) for storing the numerical values which will be used to compose, by their combination, a decimal number representing in this example a number of days to count down, here the number 365, before the triggering of an alarm.
  • the electronic control means 22 comprise a conversion table which can convert these decimal values, recorded in binary form, respectively into values from 1 to 60 corresponding to the characteristic positions of the hour hand on the dial C for that it indicates these decimal values.
  • the electronic control means 22 also include another conversion table which can convert the values 0 to 9 of these digits, selected and recorded in binary form, respectively into values from 1 to 60 corresponding to the positions of the minute hand on dial C, so that they indicate the digits 0 to 9.
  • the timepiece according to the invention further comprises two other counters or registers 31 and 33 making it possible respectively to store two digital values PMmn and PMh also comprised between 1 and 60 and corresponding respectively to a position of the two hands when they provide a alarm message, at the end of the programmed number of days, counted down.
  • the minute hand MN which is the longest and which is arranged under the hour hand H, carries, near its free end, a first part of a message, here the first two letters T and E of the mention "TEXT", while the hour hand H, which is the smallest, carries a second part of this message, the last two letters, X and T.
  • step A the two time hands H and MN display, in analogical manner and in a conventional manner, time information, for example 10h and 42mn.
  • step B of this figure 4 the two needles are brought into superimposed position under the action of independent motors 18 and 20 which are controlled by the electronic control means 22, which reconstitutes in this position the "TEXT" message written on these needles, and provides it intelligible to the user. It is in this form that the event at its end is supplied to the user (step K), that is to say visually by a clear alphanumeric message.
  • the part according to the invention further comprises an acoustic signal synthesizer circuit referenced 30, which is connected to the electronic control means 22. This circuit is activated at times chosen during the stages of programming of decimal numbers and / or when the alphanumeric message is provided to the user, i.e. when the alarm is triggered.
  • the electronic control means 22 When the watch is in the normal time display mode, and the interpretation circuit 24 (FIG. 1) transmits, in the direction of the input AN of the electronic control means 22, an activation signal corresponding to a pressure exerted on the rod, the electronic control means 22 emit a signal on their output C to place the switches 26 and 28 in state b (FIG. 1), that is to say to block the pulses coming from counters 8 and 12. Simultaneously, the electronic control means 22 read the contents of the counters 8 and 12 to know the position of the minute and hour hands. They then emit the number of pulses required on the outputs Mmn and Mh to cause the hands to be superimposed in a chosen position on the workpiece to allow the display of the indication "text" on the dial, as shown in step C of FIG.
  • This position also corresponds to the position of the hands shown in step B of FIG. 4.
  • the electronic control means cause the hands H and MN to be superimposed with regard to the index of the 9 o'clock by emitting a number of pulses equal to the number of pulses which would be necessary to make the contents of counters 8 and 12 both equal to 45, this value 45 being read from counters or registers 31 and 33.

  • the user can change the overlapping position if he wishes by pulling the rod and printing a corresponding rotation on it.
  • the PMmn and PMh values are then modified.
  • the electronic management means 22 After returning the rod from the pulled position to the rest position (step C), the electronic management means 22 remain in a standby mode until they have determined, by counting pulses of 1 Hz from of the division chain 4, that two seconds have passed. If these two seconds have passed without the control rod having been actuated again, the electronic management means will cause the two display systems S1 and S2 of the watch to display (a step E, FIG. 5).
  • first value here the largest value
  • these electronic means will simultaneously display the corresponding digit of this value. The hundreds and the number 3 are therefore displayed by these two display systems.
  • step F By pulling the rod (step F), the user can modify the position of the minute hand, to select a new digit in the range of digits from 0 to 9, in order to modify the hundreds digit by the number he wish programmed.
  • the hour hand which has an independent drive, remains fixed during this operation cannot be moved by the user. It therefore permanently indicates throughout the duration of the programming operation which class, order or weight is being processed, while the corresponding digit (quantity) can be modified by the minute hand MN , in collaboration with the second display system S2.
  • step E The modification of the hundreds being carried out, the user pushes the rod (step E).
  • the pair of values 100 and 3 which is maintained here is validated as a decimal number 300 (the order of greatest value then having the digit 3).
