- the RF module 18 is connected by a connector 19 to an antenna 2 for the transmission and / or reception of radio frequency signals.
- a communication can be established for example with a computer station or another watch not shown for bidirectional transmission of calendar data signals.
- the antenna 2 is preferably placed under the dial 8 at its periphery.
- the antenna For a transmission in the ISN band at 433.9 MHz for example, the antenna consists of a single circular turn defining a circle with the largest possible diameter in order to present the maximum gain possible in the given size of the watch.
- Icons 13 representative of a menu, an operation or a programming to be carried out, are arranged on the dial 8 around each LCD display 5 and 6.

- the electronic circuit 14 is intended to send control signals to each drive device 5 'and 6' so that at least one pointer 12 on one or the other of the displays 5 and 6 appears designating an icon of the menu, of the operation or the selected schedule.
- the manual control device for the execution of functions comprises several sensors C1 to C7 of the capacitive type.
- the beaches sensitive transparent sensors are arranged on an inner face of the glass 4.
- the number of sensitive areas is preferably equal to seven for the execution including all the functions of the calendar as explained below in reference in particular to FIGS. 4a and 4b.
- Touch sensitive ranges are shown in Figure 1 by circles in broken lines.
- marks 11 are placed on the inside of the glass 4 so as to indicate the position of each sensitive range, as well as a function of each sensor C1 to C7.
- a sensitive area of a first sensor C1 is placed in the center of the lens 4.
- Two second sensors C2, C3 have their sensitive areas arranged on the periphery glass respectively at 12 and 6 o'clock.
- Two third sensors C4, C5 have their sensitive area around the glass around the indication 3h.
- two fourth sensors C6, C7 have their sensitive area arranged on the periphery of the glass around the indication 9h.
- the third and fourth sensors C4 to C7 are grouped in pairs so as to have sensor activation zones located in the center, 3h, 6h, 9h and 12h.
- this first selected mode it is possible to execute the functions for selecting or consulting menus or various agenda cards when the sensors are activated by a user's finger.
- the pairs of sensors are separated so that each sensor controls a specific function different from electronic circuit 14 when activated.
- Each sensitive area is a circular electrode of the same dimension. All sensitive ranges C1 to C7 are separated by a greater distance or equal to the diameter of each electrode. So a user's finger 20 can be placed on the glass 4 in a determined area of a sensitive range of a single sensor to activate without influencing other neighboring sensors.
- the sensitive areas C1 to C7 arranged on the inner face of the glass 4 are each connected by a transparent conductive wire 21 at the terminals of a connector 19.
- the length of all the conducting wires, as well as their width can be identical.
- Connector 19 is used to connect the wires 21 to the electronic circuit.
- the conductive bond of each sensitive area of the sensors C1 to C7 on the electronic circuit has an equivalent resistive value so to guarantee an equivalent impedance of each sensor not activated.
- each sensor C1 to C7 includes a parasitic capacitor defined by each sensitive range and the housing 3, 3 'which is connected to the negative pole of the energy source 15. All parasitic capacitors have a substantially equal capacitive value, for example 6.5 pF.
- the electronic circuit 14 will therefore measure the capacitive value of each sensor to determine if a sensor is activated. In case the sensor is not activated, said electronic circuit only measures the capacitive value of the capacitor parasite. On the other hand, when the sensor is activated by finger 20 near the beach sensitive from the sensor, the total capacitive value is greater than a threshold value determined by the electronic circuit in order to control the execution of a function specific.
- the manual control device will be described in more detail with reference to Figure 5.
- the sensors can also be of the resistive type with touch sensitive areas placed on the outside of the glass, but in this case sensitive areas may wear out very quickly when using the device manual control.
- the sensitive areas of the sensors are connected to the circuit electronic by insulated conductors. These conductive wires are preferably placed on an inner face of the watch glass with conductive passages at through the glass to connect sensitive areas.
- the control device manual is in a sleep mode when not in use, as well as the displays liquid crystal 5, 6.
- the sensors are therefore made inactive in this mode of rest, and the watch only provides the time indication. Only by pressing latching means, such as the push button 9, that said device becomes functional.
- the needles 7 are driven by the motor 17 so as to occupy a position which does not disturb the vision of data on each display.
- a first needle can occupy a position close to the indication 9 o'clock, while a second hand can occupy a position close to the indication 3h.
- a timepiece circuit counter not shown can for example count the time during which the device operates in order to control the motor 17 to put the needles back in their initial time indication position.
- control device manual is placed in an operating mode by pressing the push button 9. Nevertheless, it can be envisaged that the device is placed in the mode of operation by activating at least one of the sensors C1 to C7 during a specified period.
- the watch becomes is in a particularly humid environment, because the sensors may be continuously activated by the presence of water on watch glass 4 1. As a result, unnecessary energy consumption may quickly drain the battery or the watch battery.
- Figures 4a and 4b show the functions of the sensors in the first and second modes selected by the electronic circuit. It is to highlight that in the first mode selected, the electronic circuit performs the same function when either of the third or fourth sensors C4 to C7 is activated. In the second mode selected, the electronic circuit performs a function different specific for each activated sensor. However in certain stages of menu or data entry selection, some sensors may not control no function to perform on the electronic circuit.
- the transition from the first to the second mode can be controlled by activating minus one of the seven sensors.
- the sensor C1 whose sensitive range is located in the center of the glass can be used to control the transition from the first mode to second mode.
- the user's finger must be placed on the glass in a determined zone of the sensitive range of the sensor C1, and maintained in this position for a sufficient time, for example greater than 2 s, for the electronic circuit interprets the passage from the first to the second mode.
- the sensors in the first mode are used to execute functions for selecting or consulting menus or various agenda cards, while the sensors in the second mode are used to compose texts, notes, addresses or various messages using games characters to select.
- the sensor C1 is used in particular for order entry into a selected menu as soon as the control device manual is in an operating mode.
- the menu to select appears on liquid crystal displays.
- the choice of a menu to select is made by the third or fourth sensors C4 to C7.
- the third C4 sensors, C5 is activated by a user's finger
- the different menus appear successively on the liquid crystal displays in ascending order determined.
- the fourth sensors C6, C7 is activated by the finger
- the different menus appear successively on the displays in a descending order determined.
- the second sensors C2 and C3 do not provide no command.
- the C1 sensor can be activated to enter the menu in question.
- a pressing the third or fourth sensors C4 to C7 will scroll the day-to-day calendar in an increasing direction with one of the third sensors C4, C5 or in a decreasing direction with one of the fourth sensors C6, C7.
- the second sensors C2 and C3 are used to scroll through the month calendar by month.
- the calendar advances from month to month, so that when the C3 sensor is activated, the calendar goes back from month to month.
- a short press on the C1 sensor will confirm the desired day.
- Different agenda card fields can be viewed by activating sensors C4 to C7 one way or the other.
- the sensor C1 can be activated for a period determined to enter a mode for editing a field in an agenda card, by example by keeping your finger on the glass facing the sensitive range of the sensor C1 for 2 s. From this moment, the pairs of sensors C4 to C7 are dissociated and so each sensor will command the execution of a function different specific to the electronic circuit.
- the sensors C4 and C6 will be used to choose a character set in one direction or in an opposite direction.
- the C2 and C3 sensors will be used to scroll for example alphanumeric characters in an increasing or decreasing direction.
- the sensors C5 and C7 will be used to move a cursor in the edited field on one of the displays in an increasing or decreasing direction. Finally, pressing the C1 sensor will finish editing and memorizing the control.
- control device manual can be configured other than what has just been described above.
- the purpose of the control device is to provide a limited number of sensors easy to handle for performing various functions of an electronic watch.
- the manual control device 30 is composed of the various sensors of the capacitive type C1 to C7, the sensitive areas of which are arranged on the face inside the glass, as well as the electronic circuit 31 to 36 for signal processing of measurement provided by the various sensors.
- the electronic circuit firstly comprises a multiplexer 31, at the input which are connected all the sensors C1 to Cn with their parasitic capacitor C1p to Cnp, and a voltage controlled oscillator 32, 36 connected to the output of the multiplexer.
- the number n of sensors is preferably equal to 7 in the device for manual control of an agenda watch.
- the task of the multiplexer is to successively and periodically connect each sensor to the input of the oscillator as a function of binary control words 40 supplied by a logic block 33 which follows the oscillator.
- the capacitive value of each sensor connected to the oscillator will be used to determine the frequency oscillation. This frequency is therefore proportional to the inverse of the value of the total capacity.
- the frequency of said oscillator is determined only as a function of the capacitive value of the parasitic capacitor C1p to Cnp.
- the total capacitive value of this sensor is greater than that of the parasitic capacitor only. This has the consequence of decrease the frequency of the oscillator so that the measurement logic block determines this variation of frequency of the oscillator for the execution of a function specific.
- the oscillator is essentially composed of a trigger rocker bistable 32 and a programmable current source 36.
- the rocker and the source of current are connected to a Vreg terminal with a regulated regulated supply voltage which can be set for example at 2.1 V.
- the current source 36 provides a current of charge I to the capacitor connected to input 42 of the oscillator until the capacitor voltage level reaches a high trigger threshold voltage of flip-flop 32.
- the current source 36 provides a discharge current I to the capacitor connected to input 42 of the oscillator until the voltage level of the capacitor drops to a low trigger threshold voltage of the rocker.
- the way of producing a charge and discharge current according to the signals of exit from flip-flop 32 are well known to a person skilled in the art in this field technical without the need to describe the current source in more detail 36.
- Such a current source 36 connected to the Vreg terminal of a regulated supply voltage is to produce a constant current over the whole range charging and discharging the capacitor.
- the charge and discharge signals of the capacitor are thus triangular shaped signals, while the signals of output of the flip-flop are pulse signals of substantially shaped rectangular.
- the measurement logic block 33 receives the pulse shape signals. rectangular to determine the frequency of these signals. Depending on the signals output of the flip-flop, the logic block 33 sends a control signal 41 to the current source for switching between the load current and the discharge current of the capacitor.
- the logic block 33 includes a pulse counter which is responsible for count the number of pulses of the output signal of flip-flop 32 in a window counting time.
- This counting window is defined by a signal CLK clock supplied by a frequency divider of the oscillator of the timepiece circuit of the watch.
- CLK clock supplied by a frequency divider of the oscillator of the timepiece circuit of the watch.
- the counted binary number of pulses for example set to 8 bits, will be used by the measurement logic block to determine if the sensor connected to the oscillator is activated or not activated by comparison with a planned threshold value.
- the duration of the counting window can be 8 ms (240 counted pulses), which corresponds to a CLK frequency of 125 Hz. maximum number of pulses counted is less than 255 which corresponds to the number maximum of an 8-bit binary word.
- this counting window can be adapted to allow counting over a longer period so as to ensure that one of the sensors has been activated.
- the measurement logic block 33 will send the control signals 40 to the multiplexer to start an initialization phase.
- all sensors C1 to Cn are connected successively to the input of the oscillator to measure the frequency of the oscillator signals for a period determined by the logic block.
- the result of the measured frequency for each sensor which corresponds to the frequency determined by the stray capacitor C1n to Cnp, is sent by bus 43 to be memorized in means of storage 35, in particular in a volatile memory RAM 35a. So when the use of the manual control device, the determined frequency of each sensor will be able to be compared with the memorized value to know if the sensor is activated or not activated.
- a Cref reference capacitor to the input of the multiplexer 31.
- the capacitive value of this capacitor eg 7.5 pF
- This capacitor can be a discrete component placed inside the shows. In this way, this Cref reference capacitor will be connected to the oscillator successively to the other sensors.
- This Cref capacitor whose capacitive value is well defined, will be used basically to adjust the value of the charge and discharge currents of the current source 36. In addition, it allows logic block 33 to perform a measurement of the frequency drift of the oscillator, for example due to the temperature variation.
- the logic block will transmit binary data by bus 44 to microprocessor means 34 linked to the means storage 35 for the recognition of the specific function to be executed from the sensor activated.
- the microprocessor means will also operate a handwriting recognition using calendar functions software. These means to microprocessor will send edited data to be stored in a memory non-volatile EEPROM 35b as a function of the binary data received by bus 44.
- the microprocessor means 34 will send control signals LCD via bus 47 to the liquid crystal display drive device for that they display desired data.
- data may be received from RF modules via bus 46 or be sent to said RF module for transmission data signals to a computer station or other watch.
- a signal Sm switch applied to microprocessor means will allow to make change the manual control device from a rest mode to a operation. This signal Sm is for example generated by the action on the push button.
- microprocessor means 34 are capable of reading information stored in unrepresented registers of the logic block of measure 33, or to send configuration parameters to said logic block.
- the capacitive value of the Cref capacitor is for example stored in one of the logic block registers to be read by microprocessor means.
