Definitions
- the present invention relates to a portable electronic device comprising an analog display device, i.e. a display by means of needles used to indicate a determined position on the dial, said position possibly be representative of any information, hourly or non-hourly.
- an analog display device i.e. a display by means of needles used to indicate a determined position on the dial, said position possibly be representative of any information, hourly or non-hourly.
- the freedom of using independent motors has inspired others modes of cooperation between the hands to display information different from the current time.
- These marks can be selected by the minute hand, the position is interpreted by a microprocessor to select from a table of match the magnetic declination of said place, to combine said declination with the signals provided by magnetic sensors of the permanent magnet of the compass and to control the motor of the hour hand to orient said needle in the direction of geographic north, or in another direction predetermined such as the direction of Mecca. If we imagined using such a watch in "reverse engineering", it would be very difficult to know by means of the needle minutes where we would be, given that even very distant from each other may have close magnetic variations or identical, i.e. having marks aligned on the same radius, for example Rome and Denver. This document therefore does not in any way suggest to designate without ambiguity at any point on the dial.
- the invention therefore aims to overcome the drawbacks of the aforementioned prior art in providing a portable electronic device with analog display having a indicating device for unequivocally showing any position over practically the entire surface of the dial, this position being representative of a any information, such as different or additional time information of the current time, or non-hourly information, or even of a game exploiting this possibility of analog display "all dial".
- This device is characterized in that the processing unit is provided with an algorithm or a correspondence table between a reference frame R i , located at any point on the dial, and angles ⁇ i , ⁇ i formed respectively by each needle from a measurement reference and in that the needles have a shape such that they can form, having the angular orientations ⁇ i , ⁇ i , an intersection of their arms above the reference frame R i , or a conjunction of their points opposite said reference frame R i .
- the elementary shape of the needles can be a needle of conventional straight shape for a needle and a broken outline for the second needle, the elbow of which will delimit a neutral zone comprising no mark R i .
- the needles can also both have a different broken outline.
- the second hand may have a symmetrical shape, for example in the heart having only one branch indexed in position ⁇ .
- the angular values ⁇ i , ⁇ i are converted into the number of motor steps, in the correspondence table or by the algorithm of the processing unit.
- the device also includes a time base which may include a calendar constituting the storage unit making it possible to display second time information by distributing the date and date on the dial month.
- the device according to the invention therefore makes it possible to display a large number information in a simpler and more economical way than with a display digital.
- a portable electronic device is illustrated by a wristwatch designated by the general reference 1 ( Figures 1 and 2), by the general reference 2 (FIGS. 3 and 4), and by the general reference 3 (figure 5).
- Figure 1 which explains the principle of the invention, shows a wristwatch 1 comprising a box 6 containing an electronic circuit having as an external control means a crown 8 on which one can exert in known manner manipulations in traction and / or rotation to select a operating mode. It also includes a dial 10, comprising at its periphery of the hour markers 12, above which two hands 14,16 are rotated by two independent motors 24,26 ( Figure 2).
- the needles have an "abnormal" shape in a technical goal, even if it can join an aesthetic concern.
- the minute hand 14 is straight, but the hour hand 16 is formed by two segments, a small segment 15, one end of which is integral with the axis in the center drive 9 of the needle and the other end forms a bend 15a with a large segment 17.
- This particular configuration allows the large segment 17 of the needle 16 to have with the minute hand 14, regardless of its angular position on the dial, a point of intersection 7 over the entire length of segment 17, except an inactive zone located inside the circle 11 described by the elbow 15a.
- the broken shape can advantageously be replaced by a curved shape having a radius of curvature decreasing as we get closer to the center.
- a curved shape having a radius of curvature decreasing as we get closer to the center.
- the angle ⁇ gives, with respect to the time reference 13, the position of the minute hand 14 with respect to a radius passing through the axis of rotation 9 of the hands and the tip of said hand 14. Similarly the angle ⁇ gives the position of the hour hand 16, it being pointed out that the angle formed by the small segment 15 of the hour hand 16 with the time reference 13 could have been taken in an equivalent manner.
- This device therefore corresponds in a way to a "bipolar" configuration by means of the angles ⁇ and ⁇ of almost the entire dial, each reference mark R i carried by the dial corresponding to a pair of values ⁇ i , ⁇ i .
- each reference mark R i carried by the dial corresponding to a pair of values ⁇ i , ⁇ i .
- the values ⁇ i , ⁇ i are expressed, not by angular values, but in numbers of steps to be taken to reach one of said angular values.
- the electronic circuit comprises a central management and control unit 20, the operating mode of which depends on the manipulations carried out on the crown 8, and which conventionally receives time signals from a time base 21.
- the electronic circuit comprises in addition to a storage unit 23 for the second information, and a processing unit 25 comprising a correspondence table containing for each value ⁇ (respectively ⁇ ) the reference mark (s) R i with which said value ⁇ is associated, so as to deliver the signal useful command to the central management and control unit 20 which then controls the supply unit 27 to drive the motors 24 and 26 by a number corresponding to the values ⁇ and ⁇ and bring the needles 14 and 16 into intersection or in conjunction above said coordinate system R i .
- Equivalently the correspondence table could be placed by an appropriate algorithm.
- a calendar watch 2 is described below, the dial of which comprises, in addition to the numbers from 1 to 12 corresponding to the hourly indices 12, the numbers from 13 to 31 referenced 22 and the months of the year referenced 32.
- the time base 21, containing registers for the dates and the months, and the storage unit 23 are therefore combined.
- the hands 14 and 16 will first cross over a mark R i indicating the date, ie the number "25" in FIG. 3, then on another mark R i indicating the month, or "December” in Figure 4.
- the needle 16 has a heart shape, which provides a more aesthetic appearance and reduces the inactive area 11 in the center.
- the central management and control unit 20 is programmed to recognize only one branch of the heart shape of the needle 16. It will also be observed that the rectilinear needle 14 thus passes over the month d 'August and points to the number 10, which corresponds to 150 engine steps from the time reference at 12 o'clock when a dial revolution corresponds to 180 steps. This means that, in the correspondence table ⁇ , the "value 150" corresponds to both August 10 and August 25. If the date to be displayed had been 10, that is to say with the tips of the hands 14,16 in conjunction, the "value 150" would also have been mapped to the number 10 in the correspondence table ⁇ .
- Figure 5 there is shown by way of illustration a game watch 3 which allows by successive presses on crown 8 to select randomly, repetitively or not, a letter of the alphabet, for example as is the case in the word game longest ".
- the letter Z that was selected corresponds in the 26th row in the storage unit 23 and its value is 45 in the table correspondence ⁇ and 30 in the correspondence table ⁇ of the unit of treatment 25.
- the storage unit 23 can also include sub-assemblies, for example example a subset 23a for vowels and a subset 23b for consonants, these subsets being for example selectable by rotating crown 8 in one direction or the other.
- subsets for example selectable by rotating crown 8 in one direction or the other.
