  FIG. 4 is a sectional view along the line IV-IV of FIG. 3.

  Figure I shows schematically the main organs of the alarm clock

  electronic, a basic electronic clock I transmits information in hours, minutes

  and current seconds to a display 3 and to two electronic comparators 4 and 5.

  The display 3 allows to display the current hour 6 and the minutes 7 and the flashing 8 of the seconds, allows to display by an indicator light 9 or 10 lit

  or extinguishes the state of authorization or inhibition of the remote alarm clock and the local alarm clock.

  The current hour 6 is set and displayed 3 by simultaneously pressing the time setting push button 1 1 and the time advance push button 13, the minutes 7 are set and displayed 3 by simultaneously pressing the push button 12 setting the minutes and the

push button 13 in advance of the hour.

  The remote wake-up time is set and displayed by simultaneously pressing push button 1il ahead of time and push button 14, the remote wake-up minutes are set and displayed by simultaneously pressing push button 12 of

  minutes and pusher 14 away.

  The local wake-up time is set and displayed by simultaneously pressing push-button 1 1 in advance of the time and local push-button 15, the local wake-up minutes are set and displayed by simultaneously pressing push-button 12 in advance of the minutes and the local pusher 15.

  Pressed alone, the time setting button 13 has no effect.

  Pressed alone, the push-button 14 for adjusting the remote wake-up time allows viewing on display 3 the hour 6 and the minutes 7 of wake-up stored for the wake-up call.

  and authorize the remote wake-up displayed by the lit status of the indicator 9.

  Pressed alone, the push-button 15 for adjusting the local wake-up time makes it possible to display on display 3 the hour 6 and the minutes 7 of wake-up stored for the local wake-up call

  and authorize the remote wake-up displayed by the lit status of the indicator light 10.

  Pressed together, the time setting push-button 13 and the remote wake-up time setting push-button 14 inhibit the remote wake-up time displayed by the

LED off status 9.

  Pressed together, the time adjustment push-button 13 and the local wake-up time adjustment push-button inhibit the local wake-up time displayed by the off status of the

LED 10.

  When the current time 2 information coincides with the remote wake-up time stored in the comparator 4 and authorized by the lit status of the indicator 9, the control signal 16 activates the low frequency generator 17 for a sufficiently long period of time to allow the low frequency generator 17 to control the miniaturized transmitter 18 with frequency modulation and to transmit its signal to

  modulation in the enclosure of the dwelling via the telescopic antenna 19.

  When the current time 2 information coincides with the local wake-up time stored in the comparator 5 and authorized by the lit status of the indicator light 10, the signal

  control 20 activates the buzzer 21 whose sound volume is adjustable 22.

  The buzzer 21 is interrupted by pressing the stop push button 23 which

  deactivates the control signal 20.

  Power supply 24 provides the energy required for all components

  alarm clock electronics.

  The power supply 24 is connected to the electrical distribution network via the appropriate electrical outlet 25. In the event of a failure of the electrical distribution network, the electric battery 26 makes it possible to rescue all the electronic components in necessary energy for at least 60 minutes. The electric battery 26

  can either be an alkaline type battery or a rechargeable battery.

  Figure 2 shows in a block diagram the operation of the transmitter 18

  miniaturized with frequency modulation of figure 1.

  impedance matching 37 and a telescopic antenna 19.

  The VCO oscillator 34 is controlled by the voltage of the low frequency signal 17 amplified by the amplifier stage 27. To give this VCO oscillator 34 good stability, this VCO oscillator 34 is incorporated in a frequency locking loop 30. The frequency of the VCO oscillator 34 is stabilized by the frequency of the quartz oscillator 29. The signal of the quartz oscillator 29 and that of the VCO oscillator 34 are applied to a signal mixer 31 and to a signal discriminator. frequencies 32 which highlights any differences between the signal from the VCO oscillator 34 and the signal from the quartz oscillator 29, this results in a correction signal filtered by the low-pass filter 33 and which is injected into the '' VCO 34 oscillator by means of the

frequency 28.

  The output signal of the VCO oscillator 34 is amplified by the amplifier 35 then subjected to another low-pass filter 36 to remove the undesirable harmonics, the signal impedance is adapted 37 before being broadcast in the enclosure housing through the antenna

telescopic 19.

  FIG. 3 is a plan view of the alarm clock 38 which comprises the housing 39, the bracelet 40, the antenna 41, the micro-receiver 42 for demodulation and signal processing, the vibrator 43 of the piezoelectric type mounted on the bottom 44 of the housing 39, and a

  push-button 45 to stop the vibrator 43.

  The alarm bracelet 38 also has an electronic member 46 which displays the time 47, either by hands as shown in FIG. 3, or by liquid crystals. The alarm bracelet also includes a dial 48 for reading the time, a time setting 49 and the batteries 50 to provide the energy necessary for all

components of the alarm clock 38.

  The micro-receiver 42 is electrically connected to the antenna 41 so that it picks up the electromagnetic signal broadcast by the telescopic antenna 19 of FIG. 1 and transforms this signal into excitation data for the vibrator 43 so as to circumstances to alert or wake up without noise perceptible to others the wearer of the alarm clock 38. The

  carrier alerted inhibits the excitation signal by manual pressure on button 45.

  FIG. 4 represents a sectional view of the alarm bracelet 38 which comprises the case 39 formed by a middle part 51, a bezel 52, a dial 48, a watch glass

53, and a background 44.

  The housing 39 includes means for receiving and processing an electromagnetic signal, these means are arranged so as to be able to pick up the signals transmitted by the transmitter of the electronic alarm clock. These means consist of an antenna 41, a

  demodulation and signal processing device carried out on an electronic assembly 42.

  The signal picked up by the antenna 41 is transmitted to the electronic assembly 42, by an electrical link 56. This detected signal is shaped by the electronic assembly 42, so as to ensure the excitation of the vibrator 43 of the type piezoelectric fixed on the bottom 44 of the housing 39 leaves via the electrical connection 57. The electronic assembly 42 is

  supplied with energy by the electrical connection 58.

  The housing 39 also contains an electronic clock member 46 supplied by the link 60 driving the hour and minute hands indicators 47, an engraved dial 48 is arranged below the indicators 47 in order to facilitate reading of the hours and minutes. The electronic assembly 42 and the electronic member 46 are fixed on a rigid base 59 arranged so as to provide the electrical connections 56, 57, 58 and 60. This base 59 is integral with the middle part 51 so as to remain fixed to the case 39 during the battery change operation 50, this change is made by dislodging the base 44 with an appropriate watchmaker tool. The middle 51 and the bezel 52 have a shaped interior recess 54

  annular in which is wound a conductive wire forming the antenna 41.

  In order to pick up the electromagnetic signals of low amplitude the middle part 51 and the bezel 52 are machined from an electrically non-conductive material and the antenna 41 must have as large an opening as possible to the electromagnetic fields. This surface is limited by the dimensions of the alarm bracelet. This limitation is compensated for by winding a number of turns adapted to the transmission frequency of the signal with modulation of

  frequency of said electronic alarm clock.

  The case 51 and the bezel 52 can be machined from a polycarbonate, which does not

  not only does not alter the aesthetics, but can also be made in different colors.

  Only the bottom 44 is machined from a metallic conductive material in order to facilitate the transmission to the wrist of the wearer of the alarm bracelet 38 of the vibrations emitted by the vibrator 43 and of ensuring the electrical continuity of the batteries 50 by means of the tongues

spring 55.
