Definitions
- the present invention relates to a device non-audible alarm, intended to equip a unit brought to the body contact, such as a watch, cell phone or a pager.
- Tactile means of information transmission offer an interesting alternative for this: is to vibrate a unit that the person wears close to the body, such as a watch for example, so to locally stimulate its epidermis to indicate a given time or the occurrence of an event (arrival of a message, a call, an appointment, etc.)
- Vibration type devices unbalance mounted on a rotor are known to the man of the job.
- the unbalance rotates at a speed of a few tens of revolutions per second thanks to an electric motor powered with a power of a few tens of milliwatts and switched on at the moment when the message must be perceived by the carrier.
- European patent application EP 0 625 738 in the name of the Applicant describes a vibrating device of a unit such as a watch.
- This device includes an electromagnetically coupled coil with a ground mobile.
- the conditions to wear induce variations of the order of 5% of the frequency clean of the whole, as well as a variation of the energy dissipated in the carrier.
- the object of the present invention is to remedy these disadvantages.
- a non-audible alarm device intended to equip a body-worn unit such as a timepiece or a mobile phone, including a case, a ground mobile inside this case intended for him transmit vibrations, a coupled coil electromagnetically to said moving mass to make it oscillate, and an excitation circuit of said coil,
- this device being characterized in that it comprises also means for measuring the instantaneous frequency of oscillation of the moving coil-earth assembly during the current oscillation, as well as means for generate during the following oscillation a series of excitation pulses from said coil, the characteristics are a function of the measurement of said instantaneous frequency of oscillation.
- the device according to the invention comprises structural members analogous to those described in the patent application European EP 0 625 738 mentioned above. It thus includes a housing (not shown), a moving mass inside of this case intended to transmit vibrations to it (not shown), and a coupled coil L electromagnetically to this moving mass.
- This coil is shown schematically on the figure 1. Its first B1 and second B2 terminals are likely to be brought to zero voltage or to a voltage VBB according to the states of four transistors of power Q1, Q2, Q3, Q4.
- transistors are controlled by a logic of LC command typically comprising first U1A and second U1B inverters, as well as first U2A and second U2B logic gates "OR".
- the first B1 and second B2 terminals of the coil L are also connected to a measuring circuit comprising a differential amplifier U3 and first U4 and second U5 comparators.
- the amplifier U3 restores the induced voltage UIND measured between the coil terminals (see curve 2-1 on Figure 2).
- the first comparator U4 compares the induced voltage UIND to 0. It provides an output signal COMP1, which is worth 1 when the induced voltage UIND is positive, and which is worth 0 when this voltage is negative (see curve 2-2 on Figure 2).
- the second comparator U5 compares the induced voltage UIND at a reference voltage REFA. It provides a signal COMP2 output, which is equal to 1 when the induced voltage UIND is greater than REFA, and which is 0 in the case otherwise (see curve 2-3 in Figure 2).
- excitation and measurement circuits described above interface with a unit likely to run a computer program, such than a microprocessor or a microcontroller M.
- the main program tests the ALARM signal (3-3), which is 1 when the device according to the invention is activated, and 0 otherwise. If ALARM is 0, the program principal repeats the test; if ALARM is 1, the main program executes the BALANCE subroutine (3-4) which is detailed in Figure 4.
- the BALANCE subroutine begins by setting the signal SHORT at 1 (4-1), the two signals DIAG1 and DIAG2 having also been set to 0 during the step initialization (3-2). Referring to the table of truth above, we see that we put the coil L short circuit, which has the effect of suffocating a possible movement of the moving coil-earth assembly.
- T2 and T3 so that their sum is substantially equal to a nominal half-period of oscillation of the moving coil-earth assembly.
- this set has a nominal natural frequency of 166 Hz, i.e. a nominal natural period of 6 ms
- the PUL variable is tested (4-17). As long as she is not equal to 1, the test is repeated. When she becomes equal to 1, in this case when UIND passes from a negative value to a positive value for the first time after the first oscillation period, the BALANCE subroutine resets the PUL variable to 0 (4-18), then return to the main program (4-19).
- the BALANCE subroutine has essential function of putting the coil-ground assembly mobile in free oscillation.
- the main program After execution of the BALANCE sub-program, the main program again tests the ALARM signal (3-5). If ALARM is reset to 0, i.e. if there is no longer instead of activating the device according to the invention, the program sets signals DIAG1 (3-6) and DIAG2 (3-7) to 0, and sets the signal SHORT (3-8) to 1. We thus suffocate oscillations of the moving coil-earth assembly.
- the main program waits for the appearance of a TIC signal (3-6 and 3-7) from of a time base.
- this time base is quartz type, and it can also be used to control other functions related to those of the device according to the invention.
- the time base will allow you to control a time display using the frequency divider usual.
- the internal variable PHASE is worth 1: indeed, it was set to this value by the subroutine BALANCE (see above). Under these conditions, the subroutine SELPHASE starts by launching the subroutine PHASE1 (see Figure 6).
- the PHASE1 subroutine begins by testing the internal variable PUL (6-1). If PULL is 0, we increment the internal variable CPT1 of a unit (6-2), then we returns to the main program (6-3). If PUL is 1, we launches the INIPER subroutine (6-4).
- VAR1 (7-1) and VAR2 (7-2) are defined as being worth a quarter and a eighth of the content of CPT1; VAR3 is equal to the sum of VAR1 and VAR2 (7-3); VAR4 is equal to VAR5 (7-4); CPT1 is set to 0 (7-5); CPT2 is equal to VAR1 (7-6); and PHASE is set to 2 (7-7). Then the subroutine INIPER returns to the main program (7-8).
- the sub-program PHASE1 allows you to totalize in the variable CPT1 the duration separating two passages consecutive of the PUL variable from 0 to 1, this duration being expressed in base units of time. We thus measure the period of the first free oscillation of the set moving coil-mass, i.e. its own period instantaneous oscillation.
- the INIPER sub-program which is launched after this instant clean period of oscillation has been calculated, used to define the characteristics of pulses that are going to be sent subsequently to the moving coil-earth assembly so as to bring it into forced oscillation. So, as we will see, VAR1 will determine the phase of these pulses, VAR4 their width, and VAR2 and VAR3 will be used to launch a procedure for safety in the event of a sudden disturbance inflicted on the unit worn close to the body fitted with the device according to the invention.
- the variable PHASE is 2. Therefore, the SELPHASE subroutine launches the PHASE2 sub-program.
- the subroutine PHASE2 begins by incrementing the variable CPT1 by one unit (8-1), then by decrementing the variable CPT2 of a unit (8-2). Then, we test the variable CPT2 (8-3). If it is different from the variable VAR4, we compare to 0 (8-4). If it is different from 0, we returns to the main program (8-5). If it is equal to 0, we put the variable PHASE at 3 (8-6) before returning in the main program (8-5).
- variable CPT2 is equal to the variable VAR4, we sets the DIAG1 signal to 1 (8-7) before returning to the main program (8-5).
- the time taken by the variable CPT2 to go from the value VAR1 at 0 is equal to a quarter of the duration which elapsed during execution of the subroutine PHASE1, i.e. a quarter of the proper period instantaneous oscillation of the coil-ground assembly mobile.
- the subroutine SELPHASE launches the PHASE3 sub-program.
- the subroutine PHASE3 begins by incrementing the variable CPT1 by a unit (9-1), then increment the variable CPT2 of a unit (9-2). Then, we test the variable CPT2 (9-3). If it is different from the variable VAR4, we compare to variable VAR1 (9-4). If it is different from VAR1, we return to the main program (9-5). If she is equal to VAR1, we put the variable PHASE at 4 (9-6) before return to the main program (9-5).
- variable CPT2 is equal to the variable VAR4, we sets the DIAG1 signal to 0 (9-7) before returning to the main program (9-5).
- the time taken by the variable CPT2 to iron from the value 0 to VAR1 is also equal to a quarter of instantaneous clean period of oscillation of the assembly moving coil-ground.
- VAR1 determines the instants 2-8 and 2-11 when the variable CPT2 is equal to the variable VAR4, and thereby the time position of the impulse 2-7 compared to the oscillation of the whole moving coil-ground.
- variable PHASE is 4. Therefore, the subroutine SELPHASE launches the PHASE4 sub-program.
- the subroutine PHASE4 starts by incrementing the variable CPT1 by one unit (10-1), then by decrementing the variable CPT2 of a unit (10-2). Then, we test the variable CPT2 (10-3). If it is different from the variable VAR4, we compare to 0 (10-4). If it is different from 0, we returns to the main program (10-5). If it is equal at 0, we put the variable PHASE at 5 (10-6) before return to the main program (10-5).
- variable CPT2 is equal to the variable VAR4
- FIG. 11 represents a first variant of the LEVEL subroutine.
- COMP2 11-1
- this signal is not worth 1, i.e. if the induced voltage UIND across the coil L is lower than the reference value REFA, we put the internal variable VAR5 to the value MAX (11-2), then we returns to the PHASE4 subroutine (11-4). If this signal is equal to 1, that is to say if UIND is greater than REFA, we put the variable VAR5 to the value MIN (11-3), then we return in the PHASE4 sub-program (11-4).
- Figure 12 shows a second variant of the LEVEL subroutine.
- COMP2 (12-1). If this signal is not worth 1, we compare the variable VAR5 at MAX value (12-2). If VAR5 is not equal to MAX, we increment it by one unit (12-3), then we returns to the PHASE4 subroutine (12-4). If VAR5 is equal to MAX, we return directly to the subroutine PHASE4 (12-4).
- VAR5 If COMP2 is equal to 1, we compare the variable VAR5 to the MIN value (12-5). If VAR5 is not equal to MIN, it is decrements by one (12-6), then returns to the subroutine PHASE4 (12-4). If VAR5 is equal to MIN, we returns directly to the PHASE4 subroutine (12-4).
- the sub-program PHASE4 sends a negative pulse (2-13) to a instant (2-14) preceding by a base unit of time the end (2-15) of the third quarter of the oscillation period of the moving coil-earth assembly.
- the role of the LEVEL sub-program is to regulate the amplitude of the oscillation of this set.
- VAR5 is in sets the value assigned to VAR4 during initialization variables that takes place at the start of each new oscillation period of the moving coil-earth assembly.
- VAR4 value determines the start and end times pulses sent to this set, and therefore their duration. Referring to Figure 2 (see 2-8 and 2-11), we understands that this duration increases when VAR4 increases, and vice versa.
- the amplitude of the oscillations of the whole moving coil-mass directly depends on the duration of pulses sent to it: the longer this duration the larger, the greater this amplitude, and Conversely.
- the two variants of the subroutine LEVEL allow, by playing on the value of the variable VAR5, to regulate the amplitude of the oscillations of the moving coil-earth assembly.
- This regulation can be done either binary, with a high MAX level and a low level MIN (variant of FIG. 11), either of gradually, with intermediate values between these two levels (variant of the figure 12).
- the SELPHASE subroutine launches the PHASE5 sub-program.
- the subroutine PHASE5 starts by incrementing the variable CPT1 by a unit (13-1), then increment the variable CPT2 of a unit (13-2). Then, we test the variable CPT2 (13-3). If it is different from the variable VAR4, we compare to variable VAR2 (13-4). If it is higher to VAR2, we compare it to VAR3 (13-5). If she is different from VAR3, we test the variable PUL (13-6). Yes PUL is not worth 1, we return to the main program (13-7). If PUL is 1, the INIPER subroutine is executed (13-8) before returning to the main program (13-7).
- variable CPT2 is greater than the variable VAR2, set the PUL variable to 0 (13-10), then return in the main program (13-7).
- variable CPT2 is equal to the variable VAR4, we set signal DIAG2 to 0 (13-11), then return to main program (13-7).
- the sub-program PHASE5 allows to interrupt the negative pulse (2-13) sent to the moving coil-earth assembly during the phase preceding at an instant (2-16) succeeding by a unit of time base the start (2-15) of its fourth quarter oscillation period.
- the two variables VAR2 and VAR3 define first (2-18) and second (2-19) moments symmetrically framing the moment (2-20) when the variable CPT2 reaches the value VAR1, i.e., theoretically, the instant the fourth quarter of the period ends the forced oscillation of the moving coil-earth assembly and where PUL returns to 1.
- the subject of successive tests of the PHASE5 sub-program is to locate the moment when PUL goes back to 1 compared to instants 2-18 and 2-19.
- the INIPER subroutine is executed, and calculates the parameters of the following period, notably from the totalized duration in the variable CPT1.
- the PHASE2 sub-program succeeds new to sub-program PHASE5, and the cycle repeats similar to itself, adapting from period to period its parameters at the oscillation frequency of the whole moving coil-mass, as well as the amplitude of this oscillation.
- the first procedure which occurs at the start of activation of the device according to the invention or during a brutal disturbance, allows to adapt the frequency and the time position of the pulses as a function of characteristics of the free oscillation of the assembly moving coil-ground.
- the second procedure which occurs during the setting in forced oscillation this set, allows to correct the frequency and phase of the pulses at the start of each new period.
- the third procedure which also takes place during the forced oscillation of the assembly moving coil-mass, allows to adjust its amplitude oscillation.
- the device according to the invention is stopped as soon as the ALARM signal goes to 0 in the program main.
- the signals DIAG1 and DIAG2 are then set to 0 and the SHORT signal is set to 1, quickly suffocating the oscillation of the moving coil-earth assembly.
- the main program then runs in a waiting loop waiting for a new passage of the ALARM signal to 1.
