Definitions

  • the invention relates to a method of telephone communication between a portable object, which includes horological functions in particular for the indication of the time and a mobile phone unit, and a dedicated server for transmission bidirectional of clock function data signals.
  • the invention relates to also a portable object for the implementation of the above method.
  • Data exchange that takes place during telephone communication between the portable object and the server mainly concerns the transmission of data for the watch functions of said object, but this exchange concerns also transmission of sound or voice data signals or signals of messages.
  • the portable object is of a size comparable to a cordless mobile telephone traditional or to a watch, for example a wristwatch.
  • the watchmaking functions of the portable object concern both the elements for indication of local time or Internet time, date or date Internet or at least one alarm, as well as software modules relating to various alarm melodies, to the control of electronic components for the indication of the time, to a selection of time zones, to the adjustment of the oscillator or the time base of the timepiece or other functions that are commonly found in watches.
  • the transmitted data are for example short information messages that are displayed on display devices phone or time information.
  • Data signals transiting between two telephone sets are of the electrical type in networks wired or radio frequency type in mobile telephony which is the case with a portable object comprising a mobile telephone.
  • the watch electronics described in this document includes means for connecting periodically and automatically said watch at a standard time signal provided by a telephone system, and means for synchronizing said watch automatically with the standard time signal.
  • This first watch which includes in particular a telephone and means for dialing a telephone number, is connected to telephone communication lines in order to receive the standard time signal provided by a talking clock. The signals received by the first watch are used first of all to set the time, as well than setting the time of other watches connected to the first watch.
  • a disadvantage of this type of watch is that it must be connected to a telephone line to receive hourly data only to correct the time it displays. Said watch is not intended for data exchange with the talking clock.
  • data signals are signals acoustic signals which must be converted into electrical signals understandable by the shows what obliges to add a conversion block to said watch.
  • the document CH 589 886 proposes the automatic time setting of a watch by approaching it to a telephone handset to receive acoustic signals timetables from a talking clock or by magnetic coupling with a transformer integrated in the telephone set.
  • Document JP 5-130256 describes a data correction system time for a calling device.
  • the calling device must first automatically dial the number of an equipment center that will compare the time data provided by said calling device and thereby provide it in return correct time data in order to make an automatic correction. This data transfer is done through a network of telephone lines.
  • the calling device is not comparable to a small portable object, such as a mobile phone or watch, but only a device that includes a timepiece circuit only to allow correction of the time between two devices in communication.
  • a device that includes a timepiece circuit only to allow correction of the time between two devices in communication One drawback is that time correction does not can only be done where these devices are connected and it is necessary to know what is the time difference between the calling device and the device called after the devices have been plugged in.
  • WO 91/11875 describes a combination of a handset telephone and a wristwatch which includes means for receiving messages, such as phone numbers, memory storage means telephone numbers, as well as means for providing the telephone numbers registered to the telephone handset to establish a telephone call.
  • the telephone handset does not include dialing keys phone numbers that are stored in the wristwatch. Furniture of these telephone numbers on the handset can be done automatically.
  • the wristwatch therefore serves in this realization of the repertoire of telephone numbers in order to transmit them to the handset without connection by a cable.
  • a disadvantage of this arrangement is that the transfer of phone numbers is done necessarily using the two elements combined and separated which must be close to each other in order to establish a connection telephone.
  • An object of the invention is to overcome the drawbacks of art documents cited above by proposing a method of telephone communication between a portable object, equipped with clock functions and a telephone unit mobile, and a dedicated server to establish a two-way transmission of clock function signals in order to allow adjustment and / or updating day of the watchmaking functions of the portable object in any geographic location and at any desired time.
  • An advantage of the process is that it is possible anywhere geographic coverage of the cellular telephone network by establishing a link telephone with a dedicated server to set the local time, Internet time, date, Internet date or update horological functions of said portable object. Connecting the portable object to the network cell phone allows to locate it geographically in case this information would be required by the server for the time zone change.
  • the server can memorize all the temporal drifts of said object during several connections between the server and the portable object, in particular for its reset to the time. Time differences after each correction of the object time are transmitted to the server during the same telephone link.
  • the server can then send update data based on an assessment of time differences memorized to act on the basis of time, for example on the frequency of the timepiece oscillator, or on a division chain of the timepiece circuit the portable object in order to remotely correct said object without the need to go to a specialized store to do it.
  • the telephone link between the server and the portable object in particular for know the functional state of said object, can be advantageously done by periods time programmed either at the portable object level or at the server.
  • the portable object can for example have in memory the telephone number of the server which can be automatically composed by defined time periods by the wearer of the portable object.
  • the server can simply warn the user of the portable object in him sending a short message informing him of the need to return it to a center specialized for the precise adjustment of its time base or the updating of certain faulty watch functions.
  • An object of the invention also consists of a portable object, such as a portable telephone watch, which enables the implementation of the telephone communication for bidirectional transmission of radio frequency signals bearing data relating to the horological functions of said object.
  • the portable object is as defined in claim 14.
  • the portable object is described only in the form favorite of a phone watch that can be worn on the wrist of a user without however limit itself to this unique embodiment, because the object could be also a mobile phone or other object with comparable dimensions.
  • the watch phone provides the advantage to the wearer of leaving both hands free.
  • Figure 1 shows schematically the elements necessary to allow the exchange of data between a phone watch 1 and a dedicated server 2 which is precisely defined to act on watch functions of the watch and also to issue various announcements for example for demonstrations or events near the wearer of the telephone watch.
  • the wristwatch type telephone watch 1 including the various elements which make it will be explained in the following description with reference to Figures 2 and 3, is worn on the wrist of a user.
  • This watch 1 includes a telephone mobile with an antenna 10 which allows it, in its basic functionality, to call a correspondent by first dialing their telephone number on said watch and then exchange voice messages with the correspondent using a microphone and a speaker or earphone built into the watch.
  • the signals transmitted 6, 6 'and 6 "and received 7, 7' and 7" by said telephone watch are radio frequency signals which pass through 3, 3 'and 3 "base stations operating on zones 4, 4 'and 4 "of a mobile telephone network. These stations base 3, 3 'and 3 "are connected by channels 5, 5' and 5" to a dedicated server 2 or telephone communication center for bidirectional transmission of data relating to the horological functions of said watch 1. In FIG. 1, only stations 3 and 3 'are in communication with the watch, which means that said watch can be detected by the two stations 3 and 3 'inside zones 4 and 4' to define its geographic position.
  • the commonly used network type which is preferably used in the present invention is the digital cellular system designated GSM which operates currently around three carrier frequencies of the order of 900 MHz, 1800 MHz and 1900 MHz on which the data signals are modulated.
  • a time division multiple access is used in the GSM standard (TDMA) and frequency division (FDMA).
  • Two frequency bandwidths can be used for transmission and reception.
  • the first bandwidth for the standard at 900 MHz is 880 to 915 MHz and the other width of band is from 925 to 960 MHz.
  • Each bandwidth is divided into 175 channels of frequency width equal to 200 KHz.
  • Each channel allows 8 communications different telephone lines which are spaced in time by multiplexing. it means that the duration of each data frame transmitted during the same telephone communication represents one eighth of the time of the duration of a period between two successive frames.
  • This distribution of communications on these frequency bands and by multiplexing is generally sufficient for a multitude of telephone communications by region.
  • it can be provided via at least one base station through which telephone communication takes place, to effect a change of frequencies (channel) in the event of heavy occupation on one or the other of the channels of transmission.
  • other standards such as the DCS1800, can be used in addition (1.8 GHz).
  • This DCS1800 standard works in TDMA and FDMA as for the GSM previously described.
  • the reader can refer to the work entitled "Practical Cellular & PCS Design" written by Clint Smith and edited by McGraw-Hill Telecommunications.
  • the use of mobile telephony according to the GSM standard makes it possible to locate relatively precisely the location of the mobile phone connected to the network cellular.
  • the telephone watch 1 can be detected in a sufficiently well defined region.
  • the method of telephone communication consists of first connecting the phone watch to the mobile phone network which would make it possible to locate the location of the wearer of watch 1 by its connection at least one 3, 3 'or 3 "base station. Then either the watch or the server manually or automatically dials the phone number of the server or watch to automatically establish communication between the two. Once the telephone connection has been established, the server 2 sends setting and / or update data to the watch destination horological functions of said watch.
  • server 2 only transmits time setting data that the watch indicates, taking also into account its location detected with respect to base stations near said watch phone 1 to set the correct time zone.
  • the server can also transmit Internet time (date) or simply date setting data.
  • watch phone 1 On reception of the radio frequency signals 7, 7 ′ carrying the data local time setting, watch phone 1 removes radio frequency signals the digital data necessary for setting the time.
  • This setting data are supplied to the microprocessor of the timepiece circuit so that a correction between the exact time, represented by 10:15 on server 2, and the time indicated by watch be done.
  • the number of steps imposed on the stepper motor, in the case of a analog type electronic watch, by the microprocessor to bring the hands to display the time of the watch in an exact position indicating the time is calculated and stored.
  • This time difference is transmitted 6, 6 'to server 2 so that he can memorize or list this specific correction time difference to said watch.
  • the telephone watch 1 comprises means for storage in which the telephone number is stored, in particular (free) from the dedicated server 2.
  • the user of the phone watch 1 can also program the periods of time when he wishes the telephone number of the server is taken from the storage means and is automatically composed to establish the telephone link with said server 2. These periods of time may be for example one or more hours, one or more days, one or more weeks, one or more months.
  • said user can also dial himself on said watch said phone number at any time when he wishes to contact the server 2.
  • the server 2 who listed all the correction time differences provided by said watch by relative to the exact actual time, can send a short message to said watch to inform the wearer of the need to monitor the functionality of their watch and advise him to bring his watch to a specialized center for checking watch functions in case the deviations in correction time are judged too important.
  • the server is responsible for transmitting to the shows update data allowing to act on the functionality of electronic components of the timepiece. It is conceivable that in the weft of data received by the phone watch, trimming data from the time base or the oscillator or the division chain of the timepiece circuit allow the microprocessor of the timepiece circuit to automatically correct and permanently the accuracy of the time displayed. This solution would avoid wearer of the watch to bring his watch to the specialized center for a repair.
  • Another solution would be to send data to the server on the frequency of the voltage pulses sent to the stepping micro-motor for advance time indication hands. A comparison is then made in the server between the pulse frequency and an exact frequency so that update data is transmitted to the watch to correct said pulse frequency.
  • the aim sought in the embodiment described above consists in compile statistics of corrections made in the server for several phone watches to inform each wearer of a phone watch during telephone communications established automatically or manually with the server. Instead of dialing the watch call to the server, said server could by specific time periods call each watch phone individually connected to the mobile telephone network. It is then necessary that the server has in memory all the particular telephone numbers of the watches.
  • the server can for example send data to download several musical melodies at the request of the bearer of the shows. These musical melodies are recorded in the storage means of the watch so that you can choose a particular melody when triggered an alarm or during a fun. This download operation of musical melodies is considered an update of a watchmaking function of the watch.
  • An update of an electronic module of the watch providing by example the indication of several time zones can also be requested from the server and transmitted during telephone communication.
  • the server can also provide data for a change of display mode to switch from a 12 hour display mode to a 24 hour display mode for a phone watch digital type.
  • the management of several applications can be done through the SIM card inserted in the phone watch.
  • the phone watch 1 could during telephone connection with the server him transmit data on the state of its energy accumulator so that the server can warn the wearer of the watch in the event of a deficiency in said accumulator, even if this function can generally be performed in the watch.
  • the server can establish a telephone connection with or without call reception tone to a phone watch particular or a set of phone watches located in a region specific in order to transmit voice or text information to them local events or events going to take place in said region.
  • the watch must include a liquid crystal display device to the recording of information messages received from the server.
  • FIG. 2 represents an electronic telephone watch of analog type plan view.
  • Said electronic watch 1 is composed of a case 18, connected to two branches of an unreferenced bracelet, of a watch dial 11, placed under an unreferenced crystal, through which an axis of rotation of the needles opens 13 for indicating the time, a crown 16 used in particular for adjusting the the time and date displayed by the watch, selection buttons 17, confirmation or erasure of selected data and a display device to liquid crystal 14 to display messages or various other data like the date for example.
  • Said watch comprises enclosed in the housing 18 an antenna 10 symbolically shown in Figure 2 for transmission 6 and reception 7 radio frequency signals during a telephone call.
  • said watch notably receives data time setting.
  • the data translated by said watch require the microprocessor of the timepiece to correct the displayed time, i.e. 10:10 a.m., at exactly 10:15 a.m., which is shown by the arrow referenced 15 on the dial and by the needle drawn in broken lines.
  • the numbers and signs 12 represented serve as both time marks and telephone dialing numbers. They are located on an indication ring 19. It is clear that a numbering specific to the time indication could also be affixed on the dial inside the ring 19 in order to have separately on the one hand the numbers and signs 12 of dialing a telephone number and on the other hand the indication digits of time.
  • An embodiment of the means for dialing a telephone number may include a keyboard formed by a plurality of capacitive sensors arranged under the watch glass used by a user to dial a number phone by placing a finger on the surface of the glass corresponding to the number or sign that he wishes to compose.
  • the watch described comprises a housing, a glass and at least one manual control device comprising a capacitive sensor provided with an electrode arranged on the inner face glass.
  • This manual control device comprises also a voltage-frequency converter whose oscillation frequency is determined by the capacity mentioned above.
  • the electrode is connected by a conductor to the converter which is housed in the housing.
  • the keyboard in question may be intended to replace the control means usual external devices, such as push buttons 17, for example used to control the various functions of a watch, such as setting the time or the switching on and off of a chronograph.
  • this keyboard can also be used as a selector to dial a number telephone if the watch is fitted with a radio telephone as in the present case invention.
  • FIG. 16 Another embodiment of the means for dialing a number telephone can be taken as an example from document EP 0 698 983.
  • the crown 16 can be arranged in three axial positions: the first, pressed and unstable for the needs in particular of confirmation of the figure chosen in mode telephone, the second, neutral and stable for the choice of said figure and the third, drawn and stable to allow time setting of the timepiece.
  • the reader can refer to this publication for more technical construction details especially to understand the steps to dial the phone number to call.
  • FIG. 3 shows the different electronic blocks which are all integrated in the case of wristwatch 1.
  • the phone watch therefore includes generally for timepiece functions a microprocessor 22 clocked at a clock frequency of around 32 kHz supplied by a crystal oscillator 22b, a non-volatile memory EEPROM 23 for data recording, a device drive the LCD display 24, an accumulator 26 intended to provide a voltage of the order of 3.6 V for the power supply of the components electronic watch and an electric charger 25 of the accumulator.
  • the microprocessor used can be for example the 8-bit PUNCH microprocessor of EM Microelectronic-Marin SA in Switzerland.
  • EEPROM memory 23 is used for recording, for example, telephone numbers, including that of the server.
  • the telephone watch 1 also includes a telephone network interface 27 which is well known.
