Definitions

  • the present invention relates to the field of display devices, and in particular electromechanical timepieces provided with an analog-type display.
  • time-setting devices actuated by a crown kinematically connected to the minute-gear train of the watch in its axial position corresponding to the setting mode are known. time, with determined gear train ratios to move the minute hand simply and quickly without having to rotate the crown either too long or often.
  • the Swiss patent CH 641630 describes an electronic device for scrolling symbols at a variable speed in response to the activation of a sensor (movement of a finger on a touch sensor, pressure on a push button).
  • the number of activations of the sensors and the duration of these activations have the effect of incrementing or decrementing the values contained in a register, which in turn determine a proportional scrolling speed. Decrementing the register values after a prolonged inactivation of the sensors makes it possible to gradually decrease the scrolling speed; however, this slowing down of the scrolling speed still lacks fluidity since the relative variations of the scrolling speed are all the greater the closer the register values are to zero.
  • This solution has the advantage of using sensors without mechanical parts; the disadvantage is that the use is less intuitive than a traditional crown. Moreover, this solution relates only to digital displays and does not apply to watches comprising analog display members.
  • the document CH 702 862 A1 describes a digital display timepiece comprising, in the embodiment of the figure 4 , a physical crown.
  • a user's action on the crown is detected and the timepiece's processor uses this information, in combination with other measured/simulated force/torque values, to perform a simulation of the actual position of the components of a simulated mechanical watch movement.
  • the figure 4 of this document that a simulation at all times of the position of the (virtual) components of a mechanical movement is displayed on the digital display device of the timepiece.
  • virtual masses, inertias and elasticities are assigned to the displayed virtual components.
  • An object of the present invention is therefore to propose a solution free from the aforementioned drawbacks of the prior art.
  • an object of the present invention is to propose a more fluid and more intuitive display device for the user.
  • An advantage of the proposed solution is to make the adjustment operation on the one hand more efficient, and on the other hand visually more intuitive thanks to the emulation of a Newtonian movement for the display means, i.e. that is, whose speed is continuous with acceleration and deceleration proportional to an applied torque or force. It is thus possible to adjust the scrolling speed to the magnitude of the correction, by first performing a coarse adjustment then a finer adjustment when approaching the desired value, with a speed that is always continuous.
  • An additional advantage of the proposed solution is that it does not require any particular sensor resolution to increment the display values.
  • the fluidity of the adjustment is ensured in particular by the fact that it is not a correction speed which is deduced from the movements of a control member, or detected by a sensor, but the acceleration of the display means. This therefore makes it possible to generate a continuous speed of these display means, in accordance with the movement of a mechanical member according to Newtonian laws of physics. This speed presents only small variations between different periods of actuation of the control member, and the proposed solution therefore does not undergo any threshold effect at the level of the sensor resulting in jerks for the movements of the control members. 'display.
  • Another advantage of the proposed solution is also to minimize the manipulations necessary for adjustment, only a few sporadic activations of the control member being necessary to adjust the position of the display elements. Furthermore the control of Adjustment operations are improved thanks to the possibility of acting not only to accelerate the speed of correction but also to decelerate this same speed.
  • An additional advantage of the proposed solution is to allow simultaneous adjustment of several display parameters, unlike the usual sequential adjustments for electronic watches.
  • the time saved by the invention for the correction thanks to a continuous movement of the display means between the periods of actuation of the activation means gives the possibility of moving, for example, the hour and minute hands at the same time. , following the intuitive approach of a classic mechanical watch, without large-scale correction taking too long in the eyes of the user.
  • a preferred embodiment of the control device of the invention is intended for timepieces and is illustrated in the figures 1A and 1B , which respectively show the logical structure of the control device 3 as well as the different parameters used and the different calculation steps carried out by various elements of the control device 3 to transform the movement of the activation means 1 into a non-proportional movement of the means display, unlike a traditional mechanical cog.
  • the Figure 1A shows the preferential structure of the activation means 1, in the form of a crown 11, the actuation of which can be performed in two opposite directions of rotation S1 and S2, as well as that of the display means 2, in the form an hour hand 22 and a minute hand 21.
  • the control device 3 according to the invention to other types of rotating mechanical display members 2, such as for example rings or drums.
  • the invention therefore makes it possible to transform a first angular speed 111, corresponding to that of the drive of the crown 11 in a given direction of rotation, for example S1, into another angular speed 211 of the minute hand 21.
  • the two angular speeds 111 and 211 are not proportional, since the minute hand 211 is progressively accelerated following the actuation of the crown 11 in the direction S1 in accordance with a Newtonian equation of movement 700 described later, which allows elsewhere to give a continuous character to the movement of the needles.
  • the control device 3 comprises an electronic circuit 31 preferably in the form of an integrated circuit comprising a processing unit 5, comprising for example a microcontroller, and a motor control circuit 6.
  • the microcontroller transforms digital input parameters, provided by a counter module 44 at the output of a first sensor 4 of movements of the activation means 1, i.e. for example the rotation of the crown 11, into instructions for the motor control circuit 6, such as for example a number of not motors.
  • the counter module 44 makes it possible to transform the electrical signals produced by the first sensor 4 into discrete digital values, and therefore manipulable by a software processing unit 5 such as a microcontroller. However, the latter is not described in detail because it is known to those skilled in the art.
  • control circuit 6 controls two separate motors, a first motor 61 being dedicated to controlling the movements of the minute hand 21, and a second motor 62 being dedicated to controlling the hour hand 22
  • the control device 3 thus simultaneously actuates a plurality of motors 61, 62 each dedicated to distinct mechanical display means.
  • the dissociation of the motors makes it possible to quickly change the display mode, by indicating, for example, the time of an alarm, or the direction of the earth's magnetic field.
  • the activation means 1 are preferably mechanical; however, they can also take the form, for example, of a capacitive sensor, such as a touch screen.
  • the actuation of the activation means 1 makes it possible to impart a variable and continuous movement to the display means 2, and in particular the minute hand 21, thanks to the calculation of an acceleration 703' in proportion to a torque value 401 'determined at the output of the first sensor 4, in proportion to the values of the register of the counter module 44, which makes it possible to characterize the movement of the activation means 1, preferably a crown 11, by digital values, namely a number of pulses .
  • the step of determining a pulse frequency 4001 is a digitization process necessary to provide an input parameter that can be manipulated by the electronic circuit 31, which can then simulate the movement of the mechanical display means as if it were determined by the application of a torque 401' proportional to the frequency of pulses 401.
  • the actual movement of the hands is considered Newtonian because it corresponds to that of a rotating solid subject to the fundamental relationship of the dynamics, indicating that the acceleration of a rotating body is proportional to the sum of the torques applied to it.
  • the fundamental dynamic equation could also be applied to linear, and not rotary, display means 2, in which case the acceleration would be proportional to the sum of the forces applied to the system.
  • the movement of the 21 minute hand is determined by solving Newton's first equation of motion 700 which models this fundamental equation of solid dynamics using a first coefficient 701 determining the torque 401' applied to the system from the pulse frequency 401, and as well as, according to a preferred embodiment, a second coefficient 702 determining a so-called fluid friction torque because causing a deceleration of the speed of rotation of the hands proportionally to this same speed.
  • the actual movement of the hands is also considered inertial because it corresponds to that of a solid in rotation which is no longer subject, as soon as the crown 11 is no longer activated, to a so-called fluid friction torque, proportional to its rotational speed itself, causing them to gradually slow down.
  • this fluid friction torque 703" is however fictitious, and simulated by the microcontroller 5 within the framework of the Newtonian equation 700 above; it is moreover not applied directly to the minute hand 21, but at the simulated speed of minute hand 703 also used to solve Newtonian equation 700 above.
  • the method for determining the speed of the display means 2 therefore solves a Newtonian equation of motion by using torque and/or force values as input parameters for the resolution of this equation.
  • These parameters are themselves determined in relation to a physical quantity, here the angular speed 111 of the crown 11, which is transformed via the first sensor 4 and the counter module 44 into a pulse frequency 401.
  • other physical quantities can however be used within the scope of the invention, such as for example a linear or angular speed, a magnetic field or a geometric angle.
  • the embodiment relating to an electronic compass described in relation to the figures 4A and 4B , uses the geometric angle as an input parameter delivered to the processing unit to determine a torque to be applied to the needle 23 indicating magnetic north.
  • the angular speed of the hands is necessarily limited due to the constraints of the system in terms of processing capabilities.
  • the first and second motors 61, 62 can only implement a given maximum number of steps per second, and there is therefore always a maximum frequency of motor steps from which the Newtonian equation of motion 700 does not can no longer be applied, because the angular acceleration necessarily becomes zero.
  • the maximum frequency of motor steps 611' of the first motor 61 controlling the minute hand 21 is preferably between 200 and 1000 Hz, which corresponds to the maximum speed of rotation of the minute hand 21 between approximately one and five revolutions per second when a complete turn of the dial corresponds to 180 motor steps. It may be noted that whatever the embodiment chosen for the invention involving the use of an electronic circuit 31, a maximum scrolling speed of the mechanical display means 2 must always be defined according to the processing capacities of the motor control circuit 6.
  • the figure 2A shows a preferred embodiment of the first sensor 4 according to the invention, which makes it possible to relatively simply determine a pulse frequency 401 used by the electronic circuit 31 in order to calculate the acceleration and/or deceleration values of the display means 1 by solving the first Newtonian equation 700 applied to this input parameter.
  • the first sensor 4 is mounted on a rod 41, fixed in rotation to the crown 11, and which can be driven in rotation in two opposite directions S1 and S2.
  • On the periphery of this rod 41 are mounted a plurality of electrical contactors 41a, 41b, 41c, 41d, preferably 4 in number, as illustrated in the figure 2A .
  • the first sensor 4 also comprises two electrical contacts 42, 43 mounted on a fixed structure, a first contact 42 at the terminals of which is measured the value of a signal 412 of output and a second contact 43 across which the value of an output signal 413 is measured when a voltage is applied to the electrical contactors 41a, 41b, 41c, 41d.
  • the figure 2B shows, in the upper part (a), the first and second signals 412 and 413 obtained during a rotation of the crown 11 in the direction of rotation S1, corresponding to the clockwise direction.
  • the first period 401a corresponding to the duration during which each signal 412, 413 is positive
  • the second period 401b during which each signal 412, 413 is zero
  • the third total period 401c corresponding to the sum of the first and second periods 401a, 401b are identical for each of the first and second output signals 412, 413, which are simply shifted in time by a value corresponding to the path of one of the electrical contacts 41a, 41b, 41c, 41d from the first contact 42 to the 2nd contact 43 external.
  • the use of the first contactor of the figure 2A to determine the frequency of pulses 401 applied to the first Newtonian equation 700 also has the advantage of not requiring any fine resolution of the first sensor 4 to guarantee the fluidity of the correction, since the speed determined by solving a Newtonian equation is always continues even if the acceleration is not.
  • a less fine resolution of the granularity of the torque values, proportional to the frequency of pulses 401 will not have the consequence of causing the display means 2 to advance jerkily, but simply of generating sharper accelerations following the detection of each additional pulse.
  • the picture 3 shows a state diagram for different sequences of time adjustment operations using hands according to a preferred embodiment of the invention applied to a timepiece.
  • Those skilled in the art will understand that it is however possible to adjust other types of parameters that are not necessarily temporal (that is to say any type of symbol) and that the hands could be replaced by other analog display devices.
  • Step 1001 corresponds to a first activation of crown 11, which makes it possible to generate the movement of minute hand 21.
  • the first sensor 4 detects a “positive” number of pulses 401 corresponding to a positive angular speed 111 for crown 11 and simulates the application of a torque, applied to the needle in the same direction.
  • the rotation of the crown 11 in the clockwise direction S1 makes it possible to advance the minute hand 21 on the dial.
  • a maximum simulated angular speed 7031 is determined as a function of the maximum motor step frequency 611'. As soon as the algorithm solving the Newtonian equation reaches this upper speed limit, it saturates, that is to say stops increasing the simulated angular speed 703 even if the algorithm were to give a result of a value superior.
  • the diagram of the picture 3 illustrates the comparison step 5003 performed by the microcontroller 5 to determine whether the speed is saturating, in which case the simulated angular speed 703 is limited to the maximum value 7031 and the angular acceleration 703' is zero for the sampling period over which the calculation has been made.
  • the feedback loop starting from the comparison step 5003 towards a positive acceleration value 703' indicates that no saturation takes place until the maximum simulated angular velocity 7031 has not been reached.
  • step 1001 has been described in the context of an activation of the crown 11 in the direction of rotation S1 of the hands of a watch to preferably advance the minute hand 21 in the same direction, it is possible also ensure that an activation of the crown 11 in the reverse direction S2 similarly rotates the minute 21 and hour 22 hands in the opposite direction, the number of pulses 401 being calculated identically for each period sampling but the information on the direction of rotation determined by the first sensor 4 makes it possible to choose the direction of rotation applied to the needles by the first and second motors 61, 62.
  • the solution proposed here according to which the movement applied to the mechanical display means is the result of an acceleration which depends on the speed of the crown, is very robust in the face of a low resolution crown. Moreover, the movement remains fluid, even if the user advances the crown in jerks: if a user rotates the crown in successive strokes, the corrections continue between the strokes. This provides significant time savings in the case where the mechanical display means are not very efficient.
  • a simultaneous adjustment of the hour hand 22 and the minute hand 21 in accordance with a totally mechanical approach, according to which the minute hand performs a complete rotation for each time change, is made possible at a speed acceptable to the user even for a relatively slow system.
  • the activation step 1001 consequently makes it possible to simultaneously adjust the hour hand 22 and the minute hand 21, which is particularly advantageous for watches electronics where each parameter is usually set sequentially for performance reasons.
  • Step 1001' is a step subordinate to step 1001, or more generally any activation step, which it immediately follows. This is a step during which crown 11, or more generally control means 1, ceases to be activated. During this step, the modeling of the invention means that no more external torque is applied to the system as soon as the detected pulse frequency 401 is zero, which depends among other things on the sampling period chosen at the level of the counter module 44 to determine the pulse frequency 401.
  • the resolution of this Newtonian equation 700 determines the inertial type deceleration of the display member, such as for example the minute hand 21 in the embodiment described above, because the deceleration is only proportional to the simulated angular speed 703 During this inertial-type deceleration, the system is in the first deceleration phase B1 illustrated in figure picture 3 .
  • the crown 11 is turned in the opposite direction S2 during an additional actuation step 1002, the angular acceleration 703' is still negative, but the B2 deceleration, shown on the picture 3 , is more pronounced because the sign of the dummy torque 401' becomes negative, acting with the angular acceleration 703' to slow the system more quickly.
  • Actuation of the crown 11 in the opposite direction makes it possible to further refine the adjustment using the additional activation step 1002 when approaching a desired value while the angular speed is at this moment there relatively high, because the second phase of deceleration B2 which is generated is more pronounced than the first phase of deceleration B1 which occurs only during prolonged inactivation of the crown 11.
  • the first activation step 1001 is therefore always followed by an acceleration phase A of the mechanical display means 2, and firstly the minute hand 21 for which the acceleration is the most perceptible.
  • This acceleration phase A ends as soon as the motor control circuit 6 detects that a maximum frequency has been reached, in this case that of step 611′ of the first motor 61, in which case a phase follows. C during which the simulated angular speed 703 is limited to the maximum angular speed value 7031. During this phase C, the minute hand 21 is therefore constant, limited by the maximum step frequency 611' of the first motor 61: the algorithm saturates.
  • any additional activation of crown 11 in the same direction of rotation S1 therefore has no impact on the real angular speed 211 of the minute hand; however, such activations make it possible to maintain the actual angular velocity 211 at this constant level by preventing the angular acceleration value 703' from becoming negative after too prolonged inactivation, corresponding according to the preferred embodiment described to a period of sampling, and which can be calibrated for example to one second.
  • the proportionality coefficients defining the moments applied to the system in the first Newtonian equation of motion 700 namely the coefficient 701 of proportionality with respect to the pulse frequency 401 and that of fluid friction 702 can preferably be chosen, together with the maximum value of motor steps 611' of the first motor 61, such that the angular acceleration value 703 is always positive as soon as at least one pulse 401 is detected per second, or respectively the value chosen for the lapse time above, so that the effective angular speed 211 always remains constant if the crown 11 is activated at least once per second as soon as the maximum angular speed 21 has been reached.
  • phase acceleration A of the display means 1 is followed most of the time by a phase C during which the scrolling speed of the display means 2 is constant as soon as the difference in the display value displayed when the adjustment is undertaken and the value to be achieved is important. If the control means are not activated for a determined period, the first deceleration phase B1 of the display means 2 takes place following this prolonged inactivation; otherwise a second more pronounced deceleration phase B2 can be actuated during an additional activation step 1002 of the control means in the opposite direction to that used during the initial activation step 1001.
  • a crown 11 In the case of a crown 11 these are opposite directions of rotation S2 if S1 was the first direction of rotation, and S1 if S2 was the first direction of rotation.
