Definitions

  • the invention relates to an interactive data entry device for a small volume instrument, in particular for a timepiece, comprising a static sensor sensitive to the touch of an operator's finger to select a sought symbol, in particular a number, a letter. or a particular sign, said sensor being formed by the juxtaposition of N electrodes delivering at their outputs at least N-1 coded information representative of the position of the finger on the sensor.
  • Document US-A-4 005 400 describes an input device composed of conductive segments. With a conductive tip, we draw on these segments the symbol that we want to introduce into the display. There is therefore no question here of a static sensor any more than there is a question of selecting a sought symbol by passing the finger over said sensor.
  • Document CH-A-10 216/73 proposes a control device for the time-setting of a timepiece.
  • This device uses two electro-mechanical switches and not a static sensor, these two switches having to be operated in a predetermined and complicated order to obtain the desired selections and corrections.
  • the document DE-A-2855935 relates to an interactive data input device for a small volume instrument.
  • the present invention relates precisely to said document to which it proposes to make a particularly advantageous improvement especially with a view to its application in watchmaking.
  • the cited application reports a data input device capable of being actuated manually and delivering information representative of the position of the finger on a sensor - resistive or capacitive - information independent of the width of the finger.
  • a sensor formed by the juxtaposition of a plurality of identical electrodes delivering to their outputs information according to a binary code representative of the finger position on the sensor.
  • the cited system already brings a significant improvement in the case of the correction of a timepiece with electrooptical display.
  • the watch includes, in addition to the main display of normal time, which appears permanently, an auxiliary display which can sequentially display an up-countdown timer, an alarm time, an agenda, a time zone, a date, etc. All of these operating modes can be indicated by permanently fixed signs engraved or transferred on the inside of the glass.
  • the sensitive button described in the cited request can first be used to select this operating mode. By moving the finger on said key, a symbol is moved which, for example, frames one of the permanently fixed signs and thus the selected operating mode is selected when the finger is lifted from the key.
  • the display corresponding to the selected operating mode switches to correction mode, which is indicated by the flashing of the display. This correction can again be made using the sensitive button. If the display chosen includes a digit or a group of two digits for example, these can be increased by moving the finger from left to right on the sensor or decreased by repeating the same movement but from right to left.
  • the cited device makes it possible to reach the desired correction much more quickly in the case where the timepiece has taken a few minutes' advance since it will suffice to move the finger from right to left over a short distance to decrease the number and thus bring it to the value of the time signal.
  • the time indications displayed by the timepiece generally include not one but two groups of associated numbers.
  • the main display of the standard time includes at least the minutes and the hours.
  • the auxiliary display may show an alarm time or a time zone, the first group of which indicates the hour and the second the minute.
  • An agenda may also appear on this display, the first group of which indicates the month and the second of which indicates the date. It is the same, in another mode, for the display of the day of the week and the date which appear simultaneously. If the watch is equipped with an up-countdown timer, this will indicate a period of time including the associated indications of the hours and minutes that it will have to count down.
  • the present invention proposes to remedy the above drawback by correcting each time indication and the groups of which it is composed as a whole, without having to go into correction mode for each of the groups one after the other. . It takes advantage of the fact that the finger can move at different speeds on the sensor and that means can be used so that at a slow speed below a threshold speed a group is corrected and that at a fast speed greater than said threshold speed, the other group is corrected.
  • Figure 1 is a top view of the timepiece in a first mode of operation according to the invention. It comprises a box 1 in which are mounted an electronic module of which the display 2 can be seen, a plurality 3, 4, 5, 6 and 7 of push buttons and a sensor 100 formed by four identical and juxtaposed electrodes 101.
  • the display 2 which can be formed from liquid crystals, comprises, in addition to the permanent display 8 of the standard time made up of three groups of two digits displaying the hours 9, the minutes 10 and the seconds 11, an auxiliary display 12 which can display for example the day of the week 13, the month 14 and the date 15. Signs 16 permanently fixed and for example transferred under the watch glass indicate the possible operating modes in which the display can be switched auxiliary.
  • the sign AG1 means “agenda 1" and the sign D the "date”.
  • a frame 17 formed of liquid crystals indicates which mode one is in. We will now describe how to set the main display to the time, how to select the operating mode and how to enter new data in the auxiliary display.
  • the time must be corrected if for some reason or other the main display 8 is ahead or behind the standard time signal time or also when the source of the signal is changed. power to the watch.
  • a short press is exerted on the push-button 7.
  • This action causes the group of numbers 11, which indicates the seconds, to flash, which indicates that we have entered the correction mode for this group.
  • a single touch of the finger anywhere on the sensor 100 causes the seconds to zero. This touch must coincide with the zero-crossing of the seconds of the time signal.
  • push button 6 which will firstly stop the flashing of group 11 and then flash groups 9 (hours) and 10 (minutes) together. These two groups are then in correction mode.
  • the finger will be moved over the sensor 100 at a first speed v i less than a threshold speed v 2 .
  • v i a threshold speed
  • the display stops flashing, which makes the correction to be made easier.
  • the numbers will increase if the finger moves from left to right on the sensor and decrease if we adopt the opposite direction.
  • the sensor has a limited number N of electrodes (four in the example), it will not be possible to add or subtract in a single transition from the finger on the sensor more than 2N-1 units to the number displayed (seven in the example), as is apparent from the patent application cited in the preamble.
  • the finger will be moved over the sensor 100 at a speed v 3 greater than said threshold speed v 2 .
  • the numbers will increase if the finger moves from left to right and decrease if we adopt the opposite direction.
  • speed v 3 is theoretically possible at speed v 3 , as for the speed Vj previously examined, to modify the displayed number of 2N-1 digits by scanning the entire sensor, numerous tests have shown that discrimination based on the only difference in speed was not sufficiently safe and that it is necessary to take into account the differences in speed which can occur during the journey during a finger excursion on the sensor.
  • Field 16 of FIG. 1 shows on two superimposed lines the various possible functions on which the timepiece can be adjusted.
  • the timepiece taken as an example, we find on the upper line and from left to right the symbols successively indicating the following functions: chronograph, down-counter timer, alarm 1 and alarm 2; on the bottom line and from left to right we find: the acoustic time signal, calendars 1 and 2, the time zone and the date.
  • this calendar indication will automatically appear on the auxiliary display, whatever the data displayed by this display, for twenty-four hours, when the date of the calendar coincides with the date of the diary 1. It should be recalled here that the choice of operating mode is made by moving the finger at speed v 1 on the sensor, rapid speed v 3 having no influence on this choice.
  • press button 6 To enter the auxiliary display correction mode, press button 6.
  • the groups 14 and 15 flash together.
  • the timepiece is then updated (group 15) by moving the finger at speed V1 on the sensor and by the month (group 14) by moving it at speed v 3 , as explained with regard to the correction. of the actual hour and minutes.
  • a second press on push-button 6 flashes group 13 representative of the day of the week which can then be set to the day of the week by moving the finger at speed v 1 on the sensor.
  • a third press on the push-button 6 brings the entire display 12 out of the correction mode and even erases the indication of the month 14 which is no longer desired.
  • the sensor 100 and the push-button 6 are acted in the same way to correct the groups 21 (month) and 22 (day) of the agenda. Pressing push-button 6 enters the diary function into correction mode, which causes groups 21 and 22 to flash together, a new pressure exiting the display of said correction mode.
  • FIG. 3 represents the block diagram of the electronic circuit associated with the timepiece represented in FIGS. 1 and 2.
  • this circuit comprises the digital sensor 100 provided with N electrodes 101.
  • the electrodes 101 of the sensor 100 deliver on the outputs 103 a binary coded information representative of the position of the finger on the sensor.
  • the N electrodes 101 of such a sensor make it possible to define 2N-1 positions of the finger, that is to say 2N-1 coded information of outputs, independently of the width of the finger. These are the N positions corresponding to the N electrodes to which are added the N-1 positions respectively between two adjacent electrodes.
  • the 2N-1 coded information supplied by N bits can be transcoded to M bits, with M ⁇ N, to simplify the associated electronic circuit and eliminate the influence of the width of the finger.
  • the transcoding circuit is shown at 104 which receives 103 at its input. N bits from the sensor and outputs a code reduced to three bits at its output 107.
  • the outputs 107 of the transcoder are connected to the input of a logic circuit 113 - certain constituent elements of which are arranged according to the cited request - which delivers at its output according to the movements of the finger on the sensor and according to the speed of movement of said finger, clock pulses 124a, 125a respectively at the input of a first (115a) or a second (115b) counter and a control signal 109a of the counting direction of said counters.
  • the outputs 116a, 116b of each of the counters supply the use circuits 111a, 111b and the displays 110a, 110b which are specific to them.
  • the logic circuit 113 further comprises and according to the invention three timing circuits 120, 121 and 122 of respective delay T 1 , T 3 and T 2 , an AND gate 124 which is active if its last two inputs are in the state 0 and its first input at state 1, an AND 125 gate which is active if its three inputs are at state 1, a D 123 type flip-flop. All these elements are arranged together and according to the invention as the diagram in FIG. 3 shows. It should be noted that the AND gates are well known in the state of the art and that the timing circuits can be constituted, for example, each by two integrated circuits of the type 555 connected in series .
  • the finger must move at a speed v 1 lower than a threshold speed v 2 on the sensor to correct the group of figures representative of the date (display 110b).
  • the finger When the finger comes into contact with one of the electrodes 101 of the sensor 100, it introduces at the input of the comparator 109 a new coded value A. As long as the flip-flop D 108 has not received a clock pulse, it maintains at its output Q, which is the coded value B present at the second input of the comparator 109, the old value of A, value which existed before the contact of the finger on the sensor.
  • the instant of contact is represented by t a in FIG. 4, which represents the operation of the device during an excursion at slow speed v i .
  • A has changed value, which is arbitrarily symbolized in the graph by a line passing from a low state to a high state.
  • the timer circuits 120, 121 and 122 can generate a short pulse (for example 2 ms) at the end of their respective time periods T 1 , T 3 and T 2 .
  • a short pulse is emitted by the timer circuit 122 after a time T 2 which is fixed, for example, at 30 ms.
  • the clock pulses of the flip-flop 108 were supplied by an external generator at 100 Hz.
  • the system proposed here and according to the invention provides an interesting improvement by the fact that the clock is internal to the system presented by the circuit 113 , which makes him walk in perfect synchronism with himself.
  • the timer circuit 121 is of the “retriggerable” or “retriggerable” type. It has the particularity of not emitting a pulse as long as its input is at state 1. On the other hand, if its input goes to state 0, it can emit one at the end of its delay r 3 , for example 25 ms, delay which begins to count as soon as said transition to state 0.
  • a timer circuit 120 which emits at its output 120a a short pulse at the end of its delay T 1 which can be, for example, 25 ms. It can also be seen that during the period which separates the time t a from the time t b , that is to say as soon as the finger has touched the sensor and remains stationary thereon, the door 125 is never active because there is never a coincidence of states 1 at its three entries by lines 109b, 120a and 123a as shown in the graph in Figure 4. Line 125a remains in state 0: no clock signal reaches counter 115b and therefore no new value appears on the display corresponding. This fact is intended in practice because it avoids untimely changes that are difficult to control.
  • the finger When the desired symbol appears on the display, symbol which can be a number, a letter or a particular sign, the finger must leave the sensor so that its value is definitively fixed either in the circuit of use 111b or in the corresponding display 110b. This moment is indicated by the time t e on the graph in FIG. 4. Since the finger is no longer in contact with the sensor, the condition A # 0 is no longer fulfilled and the line 109b goes to state 0 The short pulse appearing on line 120a at the end of the delay T1 cannot pass through gate 125 since its input 109b is at state 0.
  • the short pulse appearing on line 121a has the output Q (123a) of the flip-flop D 123 in the state of its input D, that is to say in the state 0 since once again the condition A # 0 is no longer fulfilled (arrow 132) .
  • the short pulse appearing on line 121a has the output Q (123a) of the flip-flop D 123 in the state of its input D, that is to say in the state 0 since once again the condition A # 0 is no longer fulfilled (arrow 132) .
  • the graph in FIG. 4 also shows that the counter 115a to which the display of the months corresponds never receives clock pulses. For this to be the case, it would be necessary that at a certain time the line 120a is in state 1 while at the same time the lines 123a and 109b is in state 0. However, this situation never occurs in the slow cycle just described and as shown in the graph.
  • the finger must move at a speed v 3 greater than a threshold speed v 2 on the sensor to correct the group of figures representative of the month (display 110a).
  • the counter 115b to which the date display corresponds does not receive a clock pulse in the case considered. Indeed, for this to be the case, it would be necessary that at a certain moment the lines 120a, 123a and 109b are in state 1, which is not the case as the graph in FIG. 5 shows.
  • the timing circuit 121 will emit a pulse at the end of its delay r 3 , which will result in the awareness of the counter 115b (date) as explained in About Figure 4. Then, if the finger speed were to increase above the threshold speed V2 during the same movement, we will never find the situation in the graph of Figure 5 because the line 123a is at state 1, which prohibits the activation of the door 124. This fact has an advantage because it prevents that differences in speed during a single pass can influence sometimes a counter and sometimes another.
  • the threshold speed V2 located between the slow speed v 1 and the fast speed v 3 is determined by the longitudinal dimension of the sensor. We have seen that the presence or absence of the short pulse from the timing circuit 121 at the end of its delay r 3 conditions the correction of one group to the exclusion of another or vice versa.
  • the delay T 3 running from the delay T 2 , the time to be taken into consideration for the threshold speed is therefore T 2 + T 3 .
  • the distance which separates two coded items of information on the sensor is 2.25 mm.
  • the delays T 2 and T 3 are chosen respectively at 30 and 25 ms, which gives for T 2 + T 3 a period of 55 ms. Under these conditions, the threshold speed V2 is of the order of 4 cm / sec.
  • the counters 115a and 115b can be incremented or decremented by the line 109a (A> B or A ⁇ B) depending on whether the direction of movement of the finger takes place from left to right, respectively from right to the left.
  • the reversible counters 115a and 115b can be constituted by conventional circuits known from the state of the art, such as the type 4029. More generally, it could be a microprocessor whose "software is arranged to be equivalent to what you would expect from a conventional meter. In the description which has just been given, it has been a question of correcting temporal indications displayed by a timepiece generally comprising not one but two groups of associated figures. In some cases, however, the display can only include two juxtaposed symbols which must be able to be modified independently of one another. In this case, the device described will be used to modify the first symbol by moving the finger at speed v 1 and the second symbol by moving the finger at speed v 3 .
