In a special embodiment the electronic wristwatch according to the invention contains a mercury switch (7), which switches on the display device when the watch is in the reading position. In a further embodiment, the electronic wristwatch contains an alarm clock which also consists of electronic components, but for the delivery of a Wake-up signal a piezoelectric quartz crystal or a piezoelectric ceramic component contains which is known for itself. This wake-up signal sound source has in FIG the reference symbol (4, electronic wristwatches are already known and described in U.S. Patents 3,465,033, 3,534,544, 3,560,998, 3,568,091 and 3,576,099.

An electronic watch is also described in "Electronic Design", Vol. 26, November 22, 1966. An electrically triggered alarm clock is further described in U.S. Patent 3,455,102.

The invention differs from those described above in that they are a novel combination of different electronic components Contains the wristwatch according to the invention with previously unknown advantages equips. The use of this combination has to be done later descriptive advantages have the invaluable advantage that they are completely water-light can be set up without any mechanical switches, special seals make necessary. Furthermore, it is characterized by a previously unattainable one Reliability from the sioh in high accuracy and low need for repairs express.

In the basic embodiment of the invention, one is so far under knew insensitivity to shock and impact achieved what back to it is that even the mercury switch and the wake-up signal sound source are dispensed with is and the wristwatch according to the invention with a shock insensitive Hall generator misaligned In one embodiment, the electronic one Circuitry housed on a single chip is what distinguishes the watch due to an unusual smallness that only depends on the readability of the (digital) Digit @ lattes and the volume of the battery is determined.

The term 'chip' is borrowed from the Anglo-Saxon terminology and has naturalized itself in the German technical language for an integrated Circuit made up of several layers, usually in Vaouum on one Evaporated silicon base and etching and corresponding additional processes is brought into its final form, in the consequence is occasionally instead of the term digital dial 'the term display are also used is borrowed from the Anglo-Saxon terminology and describes a device represents or displays characters and patterns with the help of optoelectronic processes.

The term digit is taken from computer terminology and describes a character or a number, in a further embodiment it is achieved that A total of eight numbers or characters can be represented although only six digits are present in the display device> which implies the use of larger characters allowed with otherwise the same dimensions. In yet another embodiment it is achieved that with the narrowest interpretation of the digital dial 'a mix-up the before.

Existing digits are excluded because two characters are preferred are in a different size and / or in a different color.

In one embodiment it is achieved that the watch is held during the Time during which it is not needed to read the time by switching off the aig »aen dial is switched to the most economical power consumption what for the service life of the battery and the display device is particularly advantageous.

In a further embodiment it is achieved that the digital The dial is switched off when it is too dark to read anyway, in one However, in another embodiment, it is ensured that the digital Dial even with insufficient light.

The one used in the electronic wristwatch according to the invention Technology is preferably that described in US Pat. No. 3,541,543 under US Pat Designation "binary decoder" and in other patents was described and the also under the technical name C / MOS technology accordingly "Complementary Metal Oxide Semioonduotor "technology, known, modified accordingly and Applied to achieve the electronic wristwatch according to the invention required switching means, switching points and effects.

The application of this technology to the production of integrated Circuits, called ICs for short, are also known. In fact it is today possible almost any low-current circuit in the form of an integrated circuit However, while trying to build integrated circuits with above average Density of the building blocks (i.e.

Transistors, diodes, etc.), limits are set where the current density cause inadequate heating in the case of undersized lines. Such However, current densities are in the electronically achen wristwatch according to the invention do not worry, since the largest electricity consumer is a preferably according to Art the "liquid crystal technology" built digital clock face, that is With this technology, light is not generated but is reflected.

As a result, however, the power requirement and voltage are kept within limits typically in the range of nano-amperes for an average segment and about 4.5 - 6 volts.

The power consumption of the wake-up signal sound source described in one embodiment, a piezoelectric quartz crystal] or a piezoelectric ceramic component, typically weighs in the range of up to about 3 mA or less, whichever Voltages applied and with what volume this element is operated target.

The circuit itself, i.e. H. all of the electronic circuitry has a power consumption of nanoampere to microampere and is therefore practical too negligible, in addition to the fact that the power consumption in the applied C / MOS - Technology essentially only occurs when a switching state changes and since the majority of the switching elements only seldom switch states Occasionally change and otherwise primarily with the few stages of the frequency divider and the oscillator, which can be operated with several kllz, can occur from Exceptionally favorable conditions are assumed when it comes to the question is about how much an electronic circuit can be compressed to one bring small number of chips. A chip is a pad on which an integrated Circuit was applied.

In fact, the entire circuit for the inventive to accommodate electronic wristwatches on a single Ghlp, but for what purpose was required, the arrangement of the vector groups and components was particularly advantageous to undertake.

The combination of various electronic elements and components consists, as already mentioned, of a quartz oscillator (Fig. 2), a Frequency divider, a decoder / driver and a display as well as electronic means to adjust the time. The invention works as follows.

A frequency is generated in the quartz oscillator, preferably one that which is divisible by 2 and is preferably in the range of 16 kHz. Frequencies this order of magnitude have the advantage that they allow a quartz crystal, the order of magnitude can be accommodated in a wristwatch without this their scope would have to be particularly enlarged.

A quartz crystal to control a frequency of about 16 than has electrical and thermal properties within a reasonable price range, which make it appear particularly suitable for use in a wristwatch. A higher vibrating crystal may have even better properties and have smaller geometrical dimensions, caused by those mentioned above Reasons for a higher power consumption, at least when using C / MOS technology is applied, The frequency generated in the quartz oscillator is preferably in a so-called Schmitt trigger converted into a square wave and divided into to make processing capable of the following frequency divider. A sine wave frequency would be difficult to process because of its relatively slow rise.

The Schmitt trigger is not shown in FIG.

At its output there is a right-o-square pulse train accordingly the sinusoidal input frequency. These square-wave pulses are used in a frequency divider fed which consists of so-called multivibrators, but occasionally also referred to as flip-fl-ops. This frequency divider is used by the Schmitt trigger The fundamental frequency coming from is divided so often in a known manner that at the output of the Frequency divider range, a frequency of 1 Hz is created. It's not decisive though whether this is a frequency of 1 Hz or 10 Hz, because with the Most watches of this type are expected to show seconds on the display, this frequency is particularly suitable. The division in the frequency divider takes place in usually by two. Other forms of frequency divider are also known; become, e.g. those where any number is possible as a divisor, this However, dividers have not yet been particularly tested and require them to operate certain conditions of which it is not certain whether they will work under all temperature conditions Can be observed, such as, for example, frequency or pulse spacing in the sequence We will therefore speak of binary counting steps, albeit in different forms can be used in the wristwatch according to the invention.

The one at the output of the frequency divider, which in reality of course represents nothing more than a kind of counter and actually works that way as such, an attached frequency of a heart serves to the first decoder / driver to display the seconds units.

Decoders / drivers are used to convert the 1 Hz signal into a combination of To deliver impulses that are suitable for operating an ulti-segment display. To the For example, a 1 is shown on a seven-segment display. required that (see Fig. 6) Segment A - D - E - F - G off and only segments B and C on are. To represent a decoder / driver it is necessary to know which one is used Process is to be worked, i.e. whether one switches on the segments that are to work or whether you switch off the segments that are not working or whether you combine both, e.g. when working with several digits.

Decoders / drivers are already known. They have been mentioned several times in the specialist literature described. One embodiment of a decoder is described below be, in particular one embodiment, the additional means for presetting includes a wake-up time.

The decoder / driver according to the preferred embodiment exists on the one hand from a chain of bistable multivibrators that form a kind of ring counter have been interconnected in such a way that whenever the end is reached the first stage follows. One gate is always open in this ring counter; this gate is advanced by one position whenever an impulse arrives. Interconnected with this ring counter (2.3) is a switching matrix (Fig. 7) in which links the decoding between two line stems (2.4) running transversely to one another cause. The individual links are represented by (2.41) diodes. the The representation in FIG. 7 is of a purely symbolic nature, in particular the counters are drawn in the form of an electromechanical device around the function as well to explain to the layperson. In reality it would of course be electronic Act switch.

As is clear from this simplified representation of the decoder to @ can be seen, a different line is used after the incremental increment controlled and thus a new combination of supply lines to the display under power set.

In the example shown, it is the subsystem for representation of 2 ten-minute units.

As can also be seen from the illustration in FIG. 7, this takes place the progression of the ring counter every 10 seconds.

Because of its function as a kind of memory from which only reads are carried out this device can also be referred to as read-only memory. There are also forms of read-only memory which are much more complex are. Such memories could of course also have the function of the ones described Take over the device.

According to the invention, the DE-coding is carried out using memory chains made up of a series of memory locations following a specific one Patterns are arranged. The individual storage chains are in chronometric Order and controlled in chronometric time intervals; this is done through Feeding of signals from the frequency divider (2.2). A wrist watch is required however, a device with which the displayed time can be adjusted, since it is conceivable that the wearer of such a watch in zones with different Time travels; It is also conceivable that for reasons that the wearer of the watch the time cannot be influenced; Summer time, winter time, etc. To adjust the time, it has been proposed to use a mechanical switch, in particular to use a reed contact to achieve a higher pulse frequency in feed the input line of the ring counter. Mechanical switches have turned pale Disadvantages, they are prone to failure and require a DurchbraGh in the housing which makes sealing difficult. Reed contacts do not require a breakthrough in the housing, but also have only a limited lifespan and are above all sensitive to impact, i.e. they can under unfavorable conditions establish contact when the clock is struck hard.

According to the invention, a Hall generator is therefore proposed to operate an electronic switch, such a Hall generator consists of a semiconductor chip through which an electric current is passed will. If the semiconductor chip is brought into a magnetic field at the same time, so part of this current is diverted transversely to the direction of the current and can pass through two Additionally attached electrodes can be taken as a so-called Hall voltage.

The height of this Hall voltage is proportional to the applied magnetic field. According to the invention, at least one Hall generator is used in one embodiment used to provide switching functions via an auxiliary circuit and an electronic switch to be triggered with the help of which it is possible to switch and adjust the Take time with a higher heart rate than for chronometric purposes is provided To carry out these functions, the Hall generator is connected in such a way that that the Hall voltage applied to its outputs in the presence of a magnetic field sufficient strength is used via the aforementioned auxiliary circuit, a circuit that electrically adapts the Hall generator to the overall circuit, if necessary, titroeme strengthened or tensions increased or dealt with, depending on the order of the day what kind of hall generator it is to operate an electronic switch. This switch connects one output of the frequency divider cascade with one who has a lower pulse rate or - in other words - bridges at least a stage of the frequency egg cascade, so that at its output instead of an output frequency For example, one heart has one on 2 hearts. In practice it has However, it has been shown to be more expedient to skip two steps so that at the output of the cascade there is a frequency of 4 hearts. With this frequency the displayed time can be switched so that the eye can easily follow the digits. It should now generally be pointless in a clock with 6 digits, two of which indicate the seconds, adjust the seconds to want although that of course would be possible in principle. According to the invention the problem can be solved in a different way. Hereafter, in an embodiment the pulse rate for adjusting the time is selected so that at the output of the frequency divider cascade, so there is a considerably higher frequency at the input for the seconds units and indeed one that allows the M i n u t n units to be switched on with a Pulse rate of about 3 to 10 pulses per second possible, but preferably one such of about 4 impulses per second in a modification of this embodiment With the help of a second hall generator an even larger number of binary Counting stages in the frequency divider cascade are bridged in this one Case such that a frequency is applied to the input of the seconds units, the switching of the S t u n d e n units with a pulse rate of preferably about 4 pulses / sec.

possible.

The invention described is operated as follows.

First the hall generator, which has the highest number of stages in the Frequency divider cascade bridged, brought into a magnetic field with which the hours are advanced in such a way that they can still be followed with the eye. As soon as the desired number of hours has been reached, the magnetic field is switched off. To adjust the minutes, a magnetic field is now applied to the Hall generator, which bridges the lower number of stages in the cascade. This is now the minutes advanced until the required number appears in the display.

The circuit according to the invention is easy to set up and has proven itself proven. However, it is also disadvantageous that in some cases with recruitment the minutes and after the hours have been set, the minutes are already too far advanced so that the displayed number shows e.g. 18 minutes during the period the desired number of minutes is e.g. OS minutes.

Here the case would arise that in particular a less practiced The wearer of the watch would have to make the setting again.

In order to eliminate this disadvantage, it is preferred that the first one the Hall generators over a switch about 4 impulses per second in the minute units directly feeds without touching the seconds and that the second of the reverb generators operated a switch that supplies approximately the same pulse rate to the hourly units without touching seconds and minutes. Such a circuit is also easy and has the advantage that all units are operated independently of each other become koeiiici.

The proposed device has another disadvantage, although it can be used to adjust the time quite well can. The expense for the device according to the invention is at least too great compared to that which can be achieved in a further embodiment.

In a further Ausgform it is therefore proposed that To take advantage of the fact that the Hall generator emits different Hall voltages if different field strengths exist, with the help of a Hall generator thus a Hall voltage available, which is higher or lower depending on the situation whether a magnet is brought closer or further away.

According to the invention, this fact is used to the effect that that the level of the Hall voltage is measured, assessed according to its level and accordingly its height is used to control various functions. After Invention is to be in the presence of low voltage via an auxiliary circuit and an electronically controlled switch connects between the preferably 4 Hz output of the frequency divider cascade and the input to the minute unit decoder / driver or its precircles are produced. In a minor modification should by a delay circuit, however, this connection only after a small one Waiting time occur, preferably after a waiting time of about 1 second, at If there is a stronger Hall voltage, however, it should again be due to an electronic one Auxiliary circuit instead of the present 4 Hz alternating voltage or square-wave pulse sequence to M i n u t e n - unit pecoder / driver to the S t u n d e n - unit decoder / driver or its precursors. A delay is also possible here, however, it has proven to be less useful. On the watch case Markings can be provided to indicate the distance between the magnets hold is to either adjust the minutes or the hours to effect.

In a special embodiment, the magnet can be rotated in the housing (Fig. 5) or slidably installed, such that the magnetic field through a slot can emerge and then comes into contact with the Hall generator.

In another embodiment, in which electronic means for To adjust the time, an IR sensor is used instead of a Hall generator used. This makes it possible just by touching a certain one Field on the clock, e.g. on the number pad, by means of the then at the output of the To perform the same switching functions of the measuring current available to the IR sensor, as described above. However, it has not kept that Use the amount of current to control different functions. Rather, it turns out to be necessary to have several sensors for several functions to use.

In yet another embodiment, instead of the Hall generator two electrodes attached to the case of the watch. When touching these electrodes with one finger, one with the electrodes is electrically directly or indirectly related circuit, e.g. 3. an oscillator circuit which detuned actuation of the electronic switch is initiated. In this case it has it is best to place the electrodes on the inside of the dial in such a way that the electrode above the numeric keypad has the functions which relate to the corresponding digit field.

However, the display must be understood here as the dial yes, there is no actual dial in the sense of the mechanical clock. Appropriately, the pair of electrodes or the electrode is also nearby and not attached directly to the digit or above the digit of the numeric field so that it is not necessary to cover the digits during adjustment. It has Proven to arrange the electrodes about 3 mm below the number.

In embodiments of the inventions described above mat it may be desirable to turn on the display only during such moments when a watch reading is intended. Investigations on the Ableocpositions a wristwatch have shown that the watch is generally in o is horizontal, with angles of up to 7 being the rule.

According to the invention, a mercury switch is used in an electronic wrist watch installed whose switching position is preferably one that is in the vertical Installation in a wristwatch within the above-mentioned 70 deviation from the horizontal for the clock. This means that the dial is activated by the mercury switch and if necessary, electronic auxiliary switching systems are switched on when the clock is is in a horizontal position. Such a position is occasionally also occur if the clock is not read, however, this is so rare that from this measure of the disconnection a significant saving of the energy for the supply of the display results.

In yet another embodiment, an additional or instead of the mercury switch, a photoresistor or preferably a photocell built-in. This ensures that the display is only switched on when if there is enough light to read the display. A reading is advantageous, for example, if the display can be recognized. It can, 'expected That the display cannot be read if the watch is behind the jacket sleeve is located.

The amount of incident light is transmitted via this photoelectric component measured and switched on or off accordingly via auxiliary circuits depending on whether the amount of light is sufficient for reading or not.

In order not to change the battery inside the watch Often to have to make, should be in a modification of the invention outputs from the battery to a Steolk'r. the with a loading device can be connected to recharge the battery.

Another measure to save a considerable amount of energy is the use of a multiplexer, i.e. a device that each a digit lights up instead of the otherwise lit or at the same time paused 6 digits With the help of the nultiplexer, which is detailed in the literature is described, the change from one digit to another happens so quickly that the eye no longer recognizes the switchover and the change and therefore the impression there is a continuous connection.

In a further embodiment, means are provided around the electronic Wristwatch according to the invention to be expanded into one that is electronic Alarm device nthaelt The means mentioned relate to an additional circuit and a piezoelectric quartz or ceramic component, furthermore electronic ones Means for adjusting and presetting the alarm time.

According to the invention, a piezoelectric ceramic flat element is preferably used connected to an oscillating circuit in such a way that the frequency of the in this oscillating circuit alternating voltage generated is preferably in resonance with the component.

Piezoelectric components used to generate signal tones suitable work with a voltage of a few volts and consume the energy im Range of mW. A typical piezoelectric ceramic component has one Resonance frequency of 2.5 kHz. To now this sound source at a preselected time To put into operation, a memory is required in which the time of triggering can be reserved. It is advisable to use the one described for the decoder / driver To use the device as a memory and only to modify it to the effect that that the counting device, which is constructed as a multivibrator chain, is not in the chronometric Senses is advanced but only via means that are also already-beforehand described how the Hall generator, IR sensor, etc., can be operated manually.

The use of a second memory makes a comparator circuit necessary to be arranged between the memories with which the state of both memories is continuously compared and when the same conditions exist, the alarm signal is triggered. This device should be described in more detail.

As can be seen from FIG. 7, all of the 0.1 Hz storage units come out 10-second pulses to the ten-second unit circuit (2.3). In this The circuit is an electronic so-holder that is used as a ring switch or ring counter is set up and in which one gate is open in each case, progressed from level to level and thereby connects a storage chain of the storage area (2.4> with the power supply circuit after the other, Via nodes, also as storage locations denotes' (2.41), which are represented here by diodes but also by transistors or the like can exist, the display (3) is according to the memory The distribution of the nodes included in the system was put into operation in segments.

To make an adjustment of the ring counter (2,3) accelerated is via the Hall generator (5.1) and an auxiliary circuit (not shown here) an increased pulse rate is supplied to the ring counter (2.-3).

The wake-up time is reserved via the ring counter (2.5) of the basically similar to the structure of the ring counter (2.3).

To adjust the wake-up time, use the hall generator (5.2> an increased pulse frequency is supplied to the ring counter (2.5), which means over the switch function of the ring counter (2.5) is a connection to the storage chains is made in the decoder / memory. Reached after the alarm time has been set electronic switch in the ring counter (2.3) the preset memory chain, see above a signal goes to the AND circuit. However, this signal is irrelevant for this period as long as there are not also signals from the symbolically appended block (2.7) to the AND circuit come. The block (2.7) contains a circuit similar to how in Fig. 7 from (2.3), (2.4) and (2.5), but in this case for hour units, , 'ehn-hour and minute units are provided.

So if a wake-up time of 12:08 pm was set, then you have to all storage chains that represent the above numbers in the corresponding areas by the (2.3) -ring counters to be reached in the AND circuit the actual To trigger the alarm signal. Such a wake-up signal would expediently be timed be limited, e.g. to about 10 seconds. In one embodiment of the invention An auxiliary circuit would limit the signal to preferably 5 Seconds, then a pause of 5 seconds followed again to sound the alarm signal for about 5 seconds.

This process would repeat itself until either the alarm clock switched off by the wearer of the watch or, on the other hand, a minute has elapsed is. In this case, the alarm clock was switched off without any further measures there after one minute the coincidence of the storage chains or else the coincidence the ring switch (2.3) and (2.5) is no longer given.

In a further embodiment, the number is to be preset the memory provided for the alarm time is limited to three, and indeed to ten-hour units, the hour units and the ten-minute units. Here is from the assumption assumed that ten-minute wake-up intervals are sufficient for normal operation.

To turn off the alarm before the end of the alarm time, a Embodiment of the rotatable or displaceable magnet shown in FIG. 5 is used. In this figure, (9) denotes the magnet which is appropriate in Fig. Ang @@@ ut @@@@ @@@@ magnetisi @ rt Can be, (10) the slot in the jacket (12) its task it the magnetic field is to be shielded from the outside and the one in another, here Not shown embodiment also partially encloses the generator, and (11) a type of adjusting wheel by means of which the magnet can be rotated. With help this device is a Hall generator which is not shown in Fig. 7, a exposed to magnetic field. The one present at the outputs of the Hall generator Hall voltage causes the AND conditions to be temporary via an auxiliary circuit be switched off. In another embodiment, the Hall generator causes that the line to the signal tone source is temporarily interrupted, namely as long as until the AND conditions no longer exist due to the incremental switching of the ring counter (2.3).

In another embodiment, symbolically represented in Pig. 8, the Hall generator is used for different purposes.

Based on the previously described fact that with different If the field strengths are also different Hall voltages, the device will 5 used to apply more or less strong field strengths to the Hall generator let it take effect. In an auxiliary circuit (2.9) is the level of the Hall voltage analyzed and, according to its height, performed one of the following functions: If the Hall voltage is low, the wake-up system is switched on, if the Hall voltage is higher the electronic switch (13) is open and the display is operated via (11), if the Hall voltage is even higher, the functions from the first two switch positions remain received, but now an @mpula sequence from the frequency divider (here from (2.11)) fed to the ring counter (2.5), whereby its progression is effected. With an even higher Hall voltage, the pulse frequency is finally obtained from the divider output (2.1), (but here is denoted by 4 Hz, of course iCnn also have a higher frequency. To have a foolproof function of the device to ensure according to Fig. 5, a resilient device is provided, which in the figure is not drawn.

This spring pulls the rotatable magnet into position 2, i.e. in the one in which the wake-up system is switched on.

The spring has no effect in position 1; it has the task of To protect magnets from inadvertently influencing the Hall generator, or - in other words - to prevent that through unwanted activity the wake-up time is adjusted by the hall generator. In addition to this device is switched on in one embodiment on the display by a character indicates that the wake-up system is in operation.

In Fig. 8 it is also noteworthy that the line generator (5.1) at low Hall voltage on the ring counter (2.3) to adjust the time takes, but with higher voltage to a different range, e.g. the hour units, is switched (9).

In another embodiment, the wristwatch is next to the A wireless device described above and in the claims Built-in receiver, as well as a well-known decoder connected downstream of it. When a @pulse sequence arrives, and indeed one that causes the decoding, a connection to the signal tone source is established and an alarm tone is generated, the lem carrier indicates that he e.g. the exchange of a Telephone system should call where further messages are stored for him. the wireless receiving system, the decoding and the generation of an alarm tone known per se. What is new here is that the system is built into a wristwatch and the signal source intended for the purpose of a built-in wake-up system is used to transmit a message.
