Definitions

  • the present invention relates to an electronic watch providing a barometric or altimetric indication based on the ambient pressure and having the features of the preamble of claim 1.
  • the invention also relates to a method of manufacturing such a watch.
  • the implantation of the pressure sensor poses problems of space, tightness, electrical connection and internal deformations due to the pressure differences between the sealed part and the chamber. pressure where prevails the ambient pressure, that is to say the atmospheric pressure, to which is added the hydrostatic pressure if the watch is immersed in water.
  • the case of the first electronic barometer and / or altimeter watches included a side appendage specifically designed to contain the pressure sensor and having communication ports with the outside. See for example patents US 4,783,772 and EP 345 929 .
  • This solution had the advantage of preserving the sealing system of traditional watch cases, but this appendix was unsightly and sometimes embarrassing. It has therefore been necessary to implant the pressure sensor inside a watch case of ordinary shape, which requires a pressure chamber in the housing. This results in additional difficulties in sealing and compressive strength within this housing.
  • the pressure sensor is housed in the housing in the vicinity of the middle part, under a platen of the clockwork against which it is maintained applied.
  • a small pressure chamber is formed between the top of the sensor and the plate and communicates with the outside via a channel that passes through the plate and the middle and opens under a rotating bezel.
  • a cover disposed between the bottom of the housing and the sensor carries electrical connections connecting the latter to an integrated circuit located next to the sensor and processing the signal to provide barometric and / or altimetric indications. Additional electrical connections are required to connect this integrated circuit to the other electrical circuits of the watch, particularly to those controlling the display.
  • the altimetric indications provided with piezoresistive sensors commonly used, relatively inexpensive, may have differences of up to about 100 m altitude.
  • an inner bottom separating the inside of the case of the watch into a sealed portion, which contains the movement of the watch, and a pressure chamber which is located between the inner bottom and an outer bottom pierced with several holes.
  • the inner bottom carries a pressure sensor that is electrically connected to the electronic control of the movement by a flexible contact tab to absorb a flexion of the inner bottom under the effect of pressure.
  • this construction has a relatively large thickness and does not solve the aforementioned problem of calibration.
  • the present invention aims to avoid the aforementioned drawbacks and relates to a watch, in particular a wristwatch, allowing an individual calibration of the indications provided by an inexpensive pressure sensor, and this thanks to an adequate construction and a manufacturing method. economically acceptable.
  • An additional object of the invention is to arrange the watch so as to ensure a good seal and avoid problems due to deformations resulting from variations in the ambient pressure in the pressure chamber.
  • an electronic watch of the kind defined above characterized in that the pressure sensor is attached to the printed circuit board provided with time-keeping circuits and electronic circuits.
  • temperature measuring means are installed on the printed circuit board and that the electronic circuits comprise a non-volatile memory in which individual calibration parameters of the pressure sensor are recorded, and it is possible to determine these parameters and save them in the memory before assembly of the instrument, as will be explained later.
  • the invention can also be implemented in an instrument devoid of means for measuring the temperature, thus also without the use of a memory for individual calibration parameters of the pressure sensor, either because a lower accuracy of the pressure measurement is accepted, either because a thermocompensated or low temperature drift pressure sensor becomes available at an acceptable price.
  • the separation means comprise a partition wall having an opening in which said sensor is placed.
  • this partition is connected to the housing sealingly along its periphery.
  • This partition supports the effect of the external pressure in the pressure chamber and thus protects the plate supporting the organs display and, where appropriate, the watch movement in the sealed part.
  • the partition wall can easily be connected to the housing in a sealed manner along its periphery, in the manner of a double bottom, and the pressure chamber extending between this double bottom and the bottom of the housing can advantageously contain a transducer electro-acoustic arranged to emit sounds in this room that communicates with the outside.
  • the sensor used is preferably a piezoresistive type pressure and temperature sensor comprising Wheatstone bridge-connected resistors in which the bridge resistance varies only as a function of temperature, while the pressure variations create an imbalance of the temperature.
  • the watch represented in Figures 1 to 3 comprises a housing 1 comprising a middle 2, a removable bottom 3 mounted on the middle with a compressible gasket 4, and a glass 5 fixed to the middle and covering a dial 6.
  • the middle part 2 supports a rotating bezel 7 bearing azimuth markers 8.
  • external control members are provided in the form of three lateral push-buttons 10, 11 and 12.
  • the casing 1 is attached to a bracelet 13.
  • a needle is provided for 14 hours and a minute hand 15 which cooperate with a conventional time scale 16 on the dial 6. These needles are also used to display other indications, as will be described later.
  • a digital display is formed by a liquid crystal cell (LCD) 17 preferably placed under a transparent window of the dial 6 and intended to display timed times obtained in a conventional manner by manipulation of the pushers 11 and 12, as well as other values which will be mentioned later.
  • LCD liquid crystal cell
  • the watch described here is also an electronic instrument performing various measurement or indication functions in addition to measurements or time indications. These additional functions, more precisely the corresponding operating modes of the watch, are represented on the dial 6 by symbols 20 to 23, while another symbol 24 (TIME) represents the conventional time display mode of the watch.
  • TIME represents the conventional time display mode of the watch.
  • the user activates the desired mode by means of capacitive control devices comprising transparent electrodes (not shown) fixed under the glass 5 above the corresponding symbols 20 to 24.
  • capacitive control devices comprising transparent electrodes (not shown) fixed under the glass 5 above the corresponding symbols 20 to 24.
  • Such control members are well known. and are described in particular in patent publications JP 49-13168 A , CH 607 872 and EP 674 247 . However, it is possible to provide different control members within the scope of the present invention.
  • the thermometer symbol 20 represents a display mode of the ambient temperature, which is indicated numerically by the LCD cell 17. This temperature is measured by means of a pressure and temperature sensor 26 which will be described more far.
  • the symbol 21 comprising a cloud and a sun corresponds to a mode of indicating the barometric tendency, indicated by the needles 14 and 15 superimposed and brought near the cloud or the sun. This trend is calculated from the pressure indications provided by the sensor 26.
  • the mountain-shaped symbol 22 corresponds to an altitude display mode, which is indicated numerically on the LCD cell 17. This altitude is calculated from from barometric indications obtained using the sensor 26.
  • the symbol 23 in the form of a compass rose corresponds to a compass function, that is to say the indication of the north by means of the needles 14 and 15 put in an aligned position and making it possible to read an azimuth on the telescope 7.
  • This direction is determined by means of a magnetic field direction sensor 27, incorporated in the instrument for example as described in the patent publication. EP 713 162 . Since the present invention essentially relates to the means used to provide barometric or altimetric indications, the other functions of the watch will not be described in detail here. It will also be noted that such a watch may also include other functions, for example a chronograph, an alarm at a predetermined time or at a predetermined altitude, an indication of the end of battery life, a radio time-out. ordered, receiving paging, etc.

  • the inside of the case of the watch is divided into a sealed part, which contains in particular the printed circuit board 30 and all the elements placed between the latter and the ice 5, and a pressure chamber 42, by means of separation comprising mainly a rigid partition wall 43 whose periphery is connected to the middle part 2 in a sealed manner by means of an O-ring 44.
  • the upper face of the partition 43 has, along said periphery and around the region of the sensor 26 , a horizontal bearing surface 45 which bears against the card 30 and, via the latter, against a suitable shoulder 46 of the middle part 2.
  • the card 30 is fixed to the partition 43 by means of screws shown, screwed into thick parts such as 47 of the partition.
  • the upper face of the partition 43 is slightly hollowed so as to leave a small vertical gap 48 between it and the card 30. This allows the partition 43 to bend under the effect of the external pressure without the risk of deforming the card 30 constituting the platen of the movement of the watch.
  • the partition 43 may be relatively thick, for example as much as the stack 40, it will be rigid enough to withstand high pressures, especially in a watch for divers. It can be made of both synthetic material and metal.
