Description

 The present invention relates to a remote control device for automatic rolling doors, and more particularly to a remote control device by radio link with predetermined coded signals, adapted to be used for the blind control of the "up", the " descent "and" stop "of automatic rolling doors.

 Usually all remote control devices for automatic rolling doors can be used only to control the raising and lowering of automatic rolling doors and, most importantly, the coding numbers used to produce the control signals between the transmitter assembly and the The receiver assembly is limited to a maximum of four digits.

Even if, luckily, a known remote control device is provided with more coding digits, the circuit arrangement is quite complicated, and therefore errors can easily occur. As a result, the problems encountered during the use of the known remote control devices are as follows:
1) Since the operational control of known remote control devices is usually limited to movements completely raised and completely lowered without any optional control function such as a halfway stop, if a child or the like hangs on the rolling door during its upward movement, this endangers the life of the child or it may result in damage to the rolling door; and
2) due to the limitations concerning the coding numbers transmitted between the transmitter and the receiving unit, if a burglar can determine the operating frequency of the remote control device by a trial and error method using the coding numbers, its chance of success in finding the exact control signals used to open the rolling door is very great at the distinct disadvantage of the owner.

Consequently, it is absolutely necessary to develop an improved remote control device comprising a simplified set of circuits but a very wide range of coding numbers.

 Thus, a main object of this invention is to create a remote control apparatus by radio link with coded signals, allowing the safe and convenient execution of control operations of "ascent", "descent" and from the "shutdown" of automatic rolling doors.

 Another object of this invention is to create a radio control remote control apparatus with coded signals for automatic rolling doors, in which the control signals can be established with 38 x 39 coding numbers in order to provide a wide variety of control signals to obtain operational safety.

According to the present invention, these and other objects are achieved by means of a remote control device by radio link with coded signals for automatic rolling doors, said remote control device comprising in combination a signal transmitter assembly. and a signal receiver assembly.The signal transmitter assembly includes a control signal tuning circuit for outputting three types of control signals at a rate of only one at a time; a three-state address coding circuit connected to the control signal control circuit for producing a multiplicity of three-state address coding numbers derived from a base 3 with multiple exponents; a counting circuit connected to the control signal adjustment circuit to provide the necessary oscillations at its output; a coded number transmitting circuit connected to the tri-state address coding circuit and the counting circuit for converting the tri-state address signals into modulated signals containing the address coded numbers for output; and a radio signal transmitting circuit connected to the coded number transmitting circuit for receiving the modulated signals of the coded numbers of three-state address and for converting them into signals for radio transmission. The signal receiver assembly includes: a pulse code modulation (PCM) decoding circuit for receiving a signal
PCM issued in a single-state series but containing three-state information and for decoding it for output; a three-state signal discrimination circuit which is connected to the PCM decoding circuit to authenticate the output signal of the PCM decoding circuit and to ensure its output; a second trigger circuit connected to the three-state signal discrimination circuit for converting the output signal of the latter into a trigger signal appearing at its output; an error correction circuit by feedback, which is connected to the second trigger circuit for returning the trigger signal to the decoding circuit PCM; and a control circuit connected to the trigger circuit and to the automatic rolling door to be controlled in order to transform the trigger signal into a control signal so as to carry out the control of the "up", "down" operations and of the automatic rolling door "stop".

Other characteristics and advantages of the invention will be highlighted, in the following description, given by way of nonlimiting example, with reference to the appended drawings in which:

Figure 6 shows a time sequence corresponding to Figure 5; and
Figure 7 is a modified circuit diagram corresponding to the preferred embodiment shown in Figure 5, in which an address circuit IC and a control circuit are removed therefrom in accordance with this invention.

 In Figures 1 and 4, a preferred embodiment of a remote control device by radio link with coded signals for automatic rolling doors is shown in accordance with this invention, this remote control device comprising in combination a set signal transmitter 1 and a signal receiver assembly 2. As shown in Figure 1, the signal transmitter assembly 1 is combined with a control signal adjustment circuit 10, a memory circuit 20, a function coding circuit 30, a three-state address coding circuit 40, a first counting circuit 50, an address conversion circuit 60, a trigger circuit 70, a coding number transmission circuit 80 and a circuit d radio signal transmission 90.

 With reference to FIG. 2, the control signal adjustment circuit 10 is mainly formed by three adjustment loops 11, 12 and 13 respectively arranged for "up", "down" and "stop" operations, loops with each of which is coupled a push button XB1, KB2, KB3. When the contacts of the pushbuttons KB1, KB2 and KB3 are not closed, the output terminals b, a and c of the loops 11, 12 and 13 are maintained in connection with the current source Vdd and are maintained in a logic state top "H". On the contrary, when the contacts of the pushbuttons KB1, KB2 and KB3 are separately closed, the output terminals b, a and c of the loops 11, 12 and 13 are switched to a low logic state "t".

 The memory circuit 20 electrically connected to the control signal adjustment circuit 10, is mainly composed of three RS flip-flops 21, 22 and 23 respectively associated with the operations of "raising", "lowering" and "stopping" the loops 11 , 12 and 13.

As can be seen in the drawing, the activation terminal S3 of the flip-flop 23 for "stop" is connected to the "stop" loop 13 while the terminal for returning to the initial state R3 is connected to the source at high potential i thereof. Consequently, when the push button KB3 is closed, the activation terminal S3 will be at a low potential level and the output Q3 at a high potential level, by providing a memory signal at its output. On the other hand, when the high potential source i goes to a low potential, the output
Q3 also provides a high potential signal at its output. Regarding the flip-flop 21 corresponding to the "climb", its activation terminal S1 is connected to the outputs b and has adjustment loops 11 and 12 via an AND gate 24. Consequently, a signal input at low potential causes the activation terminal S1 to remain in the low logic state "L". Meanwhile, when the terminal for returning to the initial state R1 is connected both to the output c of the adjustment loop 13 and to the high potential source i via another AND gate 25, the return terminal to 11 initial state R1 is normally maintained in the high logic state "H". When any of the outputs b and has adjustment loops 11 and 12 corresponding to the Xmontee: and to the "descent" is brought - at the low level "L", and when the output c of the adjustment loop 12 corresponding to the "stop" is maintained at the same time as the terminal i in the "H" state, its output Q1 transmits a signal of low level at node d, from which the low level signal is inverted via a gate
NO 26, by passing the node e to the state "H".

This high state condition at the node causes the activation terminals of the "descent" control loop 12, to which the flip-flop 21 (for ascent) and flip-flop 22 (for the descent) are connected. , since it is only when the output a of the control loop 12 is in the state "L" that a state "t" can be produced at the output Q2 of the flip-flop 22.

 If the output of the "descent" control loop 12 is maintained in the "H" state, and if an output signal occurs at node e (of high or low level), the output Q2 of the flip-flop 22 remains in state "H". The output Q2 must be maintained in the "H" state for the transmission of the signal appearing at the node e, both when the signal is found at the high level and at the low level. This condition will be highlighted in the description which follows.

 The function coding circuit 30 associated with the memory circuit 20 is essentially a high impedance semiconductor switch comprising an output terminal g and several input terminals respectively connected to the output f of the "down" flip-flop 22 and to the node e. When signals "L" are supplied by the output Q2 and by the "down" flip-flop 22, whatever the type of signals transmitted by the node e, the output of the terminal g is always kept open. On the contrary, when "H" signals are provided by the output Q2 of the "down" flip-flop 22, the input terminals of the high impedance semiconductor switch 30 are made conductive and, in this condition, if the signals "H "appear at node e, signals" L "are supplied to the output terminal q.

 The three-state address coding circuit 40 connected to the function coding circuit 30, includes a first addressing portion 41 having nine high impedance semiconductor switches in series to produce 39 = 19683 address coding numbers and one second addressing part 42 comprising eight high impedance snio-reducing switches to produce 38 = 656 address coding numbers.

Consequently, when the first and second addressing parts 41 and 42 are connected in series, the output 39 x 38 = 129,147,163 address coding numbers are obtained with them.

 It should be noted that the arrangements of the high impedance semiconductor switches of the first and of the second addressing parts 41 and 42 differ slightly from one another to produce at the output signals of "rise", of " descent "and stop having different addresses to ensure the safety of the preferred embodiment of this invention. This will become clearer in the description which follows.

The counting circuit 50 is connected to the memory circuit 20. When any of the pushbuttons KB1, K32, KB3 is pressed, a continuous memory signal coming from the memory circuit 20 is applied to a plug 12 of the circuit counting 50, and at the same time the pins 9, 10 and 11 of the counting circuit 50 are requested to make it oscillate, and a series of im
12 alternating clock pulses of division by 2 corresponding to potentials "H" and L is produced on file 1 while another series of alternating clock pulses of division by 24 and division by 213 is supplied to plug 7. Apparently, the alternating speed of the clock pulses exiting at plug 7 is the highest. Consequently, when the clock pulses are alternated twice at plug 1, only a pulse alternation clock occurred on file 2. This advantageous offset condition is used to return the alternating clock pulses to the high-potential terminal i of the memory circuit 20. As a result, when the alternating clock pulses appearing on file 2 are switched from state "H" to state "L", the high potential terminal i is caused to produce an instantaneous output "L" and to erase the
Continuous signal .. of output from memory circuit 20. In the meantime, the counting circuit 50 has stopped oscillating and, after a complete cycle of clock pulses has been output on file 2, two complete cycles of clock pulses came out on sheet 1.

 The address conversion circuit 60 connected to the counting circuit 50 and to the three-state address coding circuit 40 is essentially combined with an NI gate 61 and a NON gate 62 connected in series, the NI gate 61 being used. to receive the output signals of the plug 2 of the counting circuit 50 and of the terminal Q3 of the stop lever 23.

When signals "L" are provided by terminal Q3 of flip-flop 23, the NI gate 61 is in a validation state and a signal "H" is produced at the output
C during the time when the first half-cycle of the signal "L" is supplied to file 2 of the counting circuit 50.

On the other hand, the switching on of the switchable elements C ′ of the first address part 41 of the address coding circuit 40 is also carried out under the control of the output C during the serial production of coded addresses at its output. On the contrary, when the second half-cycle of the signal "H" is output on the plug 2, a signal "L" is output at the gate NI 61 and is converted into a signal "H" via the gate NO 62 which leaves at its terminal D and which ensures the conduction of the switchable element D 'of the second addressing part 42. However, if the signal "H" is leaving the terminal Q3 of the flip-flop of "stop" 23, whatever the type of signal supplied to file 2 of the counting circuit 50, the output D of the address conversion circuit 60 is always maintained in a "H" state. Such an arrangement is established to ensure that, each time the push button KB3 is pressed, the coded address signal of the second addressing part 42 can be immediately supplied at its output.

The first trigger circuit 70 connected to the counting circuit 50 and to the memory circuit .20 is essentially an OR gate arranged so as to receive the output signals from the circuit
memory 20 and of the card 2 of the counting circuit 50 when a signal "H" coming from one or the other of said circuits causes an OR state trigger signal to exit from the OR gate 70.

 The coded number transmission circuit 80 connected to the counting circuit 50 and to the first trigger circuit 70 is composed of an integrated circuit PCM with three state addresses, such as circuit IC 145026 manufactured by Motorola Corporation, in which the signals coming from the plug 7 of the counting circuit 50 are received by the transmission circuit of coded numbers 80 on the plug 11 and are used as pulses; clock thereon, while the signals coming from the triggering circuit 70 are received on card 14 and used as a trigger signal for it. In addition, cards 1 to 7 as well as cards 9 and 10 of the transmission circuit 80 function like the address cards and are respectively connected to the corresponding high impedance semiconductor switches of the three-state address coding circuit 40. Consequently, when the integrated circuit PCM 80 is triggered, the address signals coming from the first addressing part 41 or from the second addressing part 42 are modulated and leave by the plug 15 of the integrated circuit 80.

 It should be noted that, since the PCM circuit available on the market - at present is usually limited to 9 pins for addressing, only nine high-impedance semiconductor switches can be connected in series with the first and second parts of addressing 41, 42.

 The radio signal transmission circuit 90, connected to the coded number transmission circuit 80, is conventionally combined with an HF oscillator, a modulator, an amplifier and an antenna to convert the modulated signals received from the transmission circuit of numbers coded 80 in radio signals and to transmit them.

 FIG. 3 shows a time sequence of the signal transmitter-assembly 1 represented in FIG. 2. As indicated, when the "descent" button KB2 is pressed, a signal "L" leaves the terminal f of the "down" flip-flop 22 and of terminal d of the "up" flip-flop 21 where the state "L" appearing at terminal d is transmitted to the coding circuit 30 as well as to the return terminal at the initial state R2 of the "descent" flip-flop 22 via the terminal e of the gate NO 26. On the other hand, since the terminal returning to the initial state R2 of flip-flop 22 is located at the state "E", the output f is at the low level, causing the opening of the coding circuit 30, so that an open signal is produced at its output q. In the preferred embodiment of this invention, the "open" signal represents the "down" control position. In addition, the output signal appearing at terminal k is a low potential signal which is used to trip the circuit. counting 50 in order to produce the oscillation necessary for its output and, since the output 3 is also at a low potential level relative to the terminal Q3 of the "stop" flip-flop 23, the coded addresses coming from the first and from the second addressing parts 41 and 42 exit at the terminal n in a series of positive-negative half-cycles.

 When the push-button KB1 corresponding to the "rise", or KB3 corresponding to the "stop" is pressed, the output signal at terminal f is always in the "H" state. Consequently, if the push button "up" KB1 is pressed, a signal "H" coming from terminal e leaves at terminal q. In the preferred embodiment, this signal "H1 represents the control position for" up ". However, if the push button KB3 is pressed, a signal" 1 "from terminal e leaves at terminal i and this signal" 1 "represents in the preferred embodiment the" stop "control position.

On the other hand, if two of the three KB1 pushbuttons,
KB2 and KB3 are pressed simultaneously, the resulting operations are clearly highlighted on the
Figure 2 where the sequence includes first "stop" then "descent" then finally "climb". It should be noted that each time the push button is pressed, only one signal can go out. In the preferred embodiment, the "stop" signal intervenes first in the sequence simply by the fact that the inventor of this invention considers that the stop condition is important for automatic rolling doors but obviously there is no limitation to this configuration. It should also be noted that modifications can easily be made to the preferred embodiment of the transmitter assembly 1, for example by modifying it for the execution of a two-state function corresponding to the "climb" and to the "descent" and the like, without departing from the scope of this invention.

 FIG. 4 shows a preferred embodiment of the signal receiver assembly 2 in accordance with the invention, this signal receiver assembly 2 being essentially combined with a design decoding circuit with pulse code modulation PCM 110, a three-state signal discrimination circuit 120, a second trigger circuit 130, a feedback error correction circuit 140 and a control circuit 150.

 As shown in Figure 5, the PCM signal decoding circuit 110 is combined with a superheterodyne receiver 111, a first three-state address PCM integrated circuit MSI1 and a second three-state address PCM integrated circuit MSI2.

The first three-state PCM integrated circuit, such as the IC-145028 integrated circuit manufactured by Motorola
Corporation, includes 9 address codes ranging from Al to A9 and which are capable of decoding up to 39 coding numbers, a first oscillating loop RC,
R21 - C22, and a first RC synchronization circuit,
R23 - C24, respectively connected to plugs 6, 7 and 10. The three-state PCM signals transmitted in a series with a single state of the transmitter assembly 1 are first compared by the first oscillating circuit RC,
R21 - C22 for frequency identification, they are decoded by means of address codes A1 to A9 of the IC-MSI1 circuit for identification of the coding number, then the identified signals are authorized to leave sheet 11 within the limit
time set by the first counting circuit RC,
R23 - C24. The second integrated circuit PCM MSI2, identical to the integrated circuit IC-145028 above, has eight address codes ranging from Al to A8, a second oscillating circuit RC, R24 - C26 and a circuit of RC counting,
R25 - C27, separately connected to plugs 6, 7 and 10 of the IC-MSI2 circuit, of which plug 12 is used as a function code while plug 11 is used as an output code.
Three-state PCMs received as a single-state series from the transmitter assembly 1 are separately compared in frequency via the second RC circuit, R24 - C26, and are decoded into coding numbers per l intermediary of the address codes going from A1 to A8 so as to produce the identified signals corresponding to card 9, while an additional "H" signal leaves through card 11 in a time set by the second counting circuit RC , R25 - C27. As the drawing shows, the integrated circuit IC-MSI1 is connected to the integrated circuit IC MSI2 in series via an AND gate 113. It should be noted that the duration of the period established by R23 , C24 in the counting circuit of IC-MSI1 is sufficient to allow the circuit
IC-MSI2 to receive a complete transmission of two PCM single state signals so that high selectivity among 38 x 39 coding numbers can be obtained. The use of the function code sheet 12 of the IC-MSI2 circuit ensures that, when its input is at a high level and when two different waveforms are also applied to sheet 9, sheet 11 produces a long and high level signal established by the RC circuit, R25 - C27, and another short and high level signal established by the RC circuit, R24 - C26. These two different synchronization signals represent respectively, in the preferred embodiment, the "up" signal and the "down" signal. On the contrary, when the input signal to the function code plug 12 is a low level signal when another predetermined waveform is applied to the plug 9 while a high level signal is applied to the sheet 11 in the period established by the RC circuit,
R25 - C27, this low level signal represents the "stop" signal, and all other signals are not recognized.

The three-state signal discrimination circuit 120 is combined with an "up" state discrimination loop 121, a "down" state discrimination loop 122, and a state discrimination loop d "'stop' 123, the "climb" state discrimination loop 121 being composed of a first AND gate 124a, the input terminals of which are connected separately to plugs 11 and 12 of the second circuit IC-MSI2, d ' an RC loading loop,
R29 - C29, a first door NO 124b and a second door NO 124c, respectively connected in series; the “descent” state discrimination loop 122 comprises a third NON gate 125a connected to the output of the first AND gate 124a of the “ascent” state discrimination loop 121, an unloading loop RC, R31 - C31, and a second AND gate 125b. Since the first AND gate 124a is connected to pins 11 and 12 of the second IC-MSI2 circuit, when input k of the function code card 12 and input Z of a synchronization signal R25 x C27 from plug 11 are both at a high level, the output m of the first gate 124a is at a high level for a period of time established by the circuit
RC, R25 - C27. Since the duration of this signal "H" coming from R25, C27 is sufficient for the loop R29, C29 to be charged at a high voltage level, its output n is at a high level and, via the first and second NON 124b and 124c gates, this signal "H" remains at a high level at the output r of the second NON 124c gate.

In the preferred embodiment, this "H" signal is the "climb" signal. However, when the plug 11 of the second circuit IC-MSI2 produces at its output a signal "H" of a duration established by the circuit RC, R24 - C26, because the configuration of the preferred embodiment of the invention is based on
R25 x C27> 2/3 R29 x C29, the duration of the "H" signal from the RC circuit, R24 - C26 does not allow the RC load circuit, R29 - C29 of the "climb" state discrimination loop 121 to be charged at a high voltage level. Consequently, the output o of the first gate NO 124b is also at a high level. Meanwhile, when the signal "H" of the first AND gate 124a has been converted into a signal "L" via the third gate NO 125a, the RC unloading circuit, R31 - C31 has discharged to a low voltage level in the time predetermined by the RC circuit; on the contrary, upon reception of the signal "H" coming from the output o of the first gate NO 124b and from the output p of the unloading circuit RC, R31 - C31, the second AND gate 125b produces at its output a signal " H ". This output signal "H" is the "descent" signal in the preferred embodiment.

The "stop" state discrimination loop 123 is composed of a fourth NO gate 126a and a third AND gate 126b, which are respectively connected to plug 11 and to plug 12 of the second IC-MSI2 circuit. , when the output of plug 12 is a signal "L" while the output of plug 11 is a signal "H" having a duration established by the circuit RC,
R24 - C26, -the output s of the third AND gate 126b will be a "H" signal which is the "stop" signal in the preferred embodiment. Because the output signal of the first IC-MSI1 circuit is transmitted to the first AND gate 124a of the "descent" state discrimination loop 122 via an OR gate 114, when the input of the plug 12 of the second IC-MSI2 circuit is at the state "L" and has been converted to state "H" via the fourth gate NO 126a, the signal applied to the third AND gate 126b is always maintained in state "H".

In this condition, as soon as the superheterodyne receiver 111 produces a signal at its output, this output signal is instantly coded by the second circuit.
IC-MSI2 so as to appear at the exit of it.

This constitutes the instantaneous "stop" configuration specifically established in the preferred embodiment of this invention to produce an emergency stop of the automatic rolling door.

The second trigger circuit 130 is essentially combined with an RC loop, R26 - C28, and with three groups of SCR silicon-controlled rectifier loops and RL relay, namely
SCR1, RL1; SCR2, RL2; and SCR3, RL3, these loops being respectively connected to the discrimination loops of "climb", "descent" and "stop" states 121, 122 and 123. When a signal leaves the corresponding discrimination loops 121, 122 and 123, the associated SCR rectifier is energized so as to activate the corresponding relay RL. It should be noted that the RC circuit, R26 - C28, is arranged so as to maintain the trip circuit 130 in a stable condition. Furthermore, since the holding current (IH) of the resistor R26 and of the relay RL is lower to that of the SCR rectifier, after the capacitor C28 has stepped over the SCR rectifier so as to maintain a holding current, the SCR rectifier is blocked.

 As a result, waves in the form of very small peaks are produced by the SCR rectifier so that it is not necessary to connect an RC loop with each SCR rectifier.

The correction circuit 140 is mainly composed of a diode loop D3, D4 and an integration loop C32, R32. As can be seen in the drawing, when any of the groups with rectifiers SCR and relays RL, namely SCR1, RL1;
SCR2, RL2; and SCR3, RL3 is excited to become conductive, a sine waveform signal is generated at the terminals of the diode loop D3, D4 and is rectified by it, and then the rectified signal is clipped by a diode D2 and it is inverted in the form of a signal "L" via the integration loop C32, R32 from which a signal "L" is returned to the plug 12 of the second circuit IC-MSI2.

The control circuit 150 is combined with an "up" control loop 151, a "down" control loop 152 and a "stop" control loop 153, the up and down control loops 151, 152 being placed respectively under the control of relays RL1 and RL2 with coupling effect. When the "up" relay RL1 or the "down" relay RL2 is activated, the coil U or D of the "up" or "down" control loops 151, 152 is energized so as to drive the corresponding mechanism the automatic rolling door in order to raise or lower it.However, when the automatic rolling door has reached the position established by a contactor-limiter LSU (for ascent) or LSD (for descent) during its movement the associated circuit is de-energized and the coil U or D is therefore demagnetized and returned to its original state. On the other hand, when the "stop" control loop 153 is connected in series with the "up" and "down" control loops 151 and 152, and when the stop control relay
RL3 is activated, both the "up" control loop 151 and the "down" control loop 152 are disabled.

 In Figure 6, there is shown a time sequence of operation of the preferred embodiment shown in Figure 5. As shown in Figure 6 t the time sequence is divided into three parts a, b and c respectively representing the operations of " climb "," descent "and d1,, stop".

When the input terminals Z and k of the first door
ET 124a are in an "H" state and when terminal 1 is associated with a time period of a duration defined by R1S x C27 of the second IC-MSI2 circuit, the output m of the first AND gate 124a produces a signal "H" with a duration established by R25, C27. This output signal "H" is then switched to a high voltage level on the input terminal n via the circuit charge and discharge operations.
RC, R29 - C39, and, after successive conversions made via the first and second NON gates 124a and 124b, a signal "H" is produced at the output r. Figure 6 (b) shows a time sequence of the "descent" operation.

When another signal "H" having a duration defined by R24, C26 of the second circuit IC-MSI2 is applied to the first AND gate 124a, its output m is also in a state "H". However, due to the short period established by R24, C26, this state "E" cannot allow the circuit RC, R29 - C29, of the "climb" control loop 121 to charge at a level of high tension. As a result, the output of the "climb" control loop 121 is maintained at a state "L". Meanwhile, the signal "H" defined by
R24, C26 has been inverted as an "L" signal via the third NO gate, causing the RC discharge circuit, R31 - C31, to suddenly change to an H "state and then begins to discharge so that a signal "H" is produced at terminal q of the second AND gate 125b.

 It should be noted that the preferred embodiment of the signal receiver assembly 2 shown in FIG. 5 can be modified so as to include only an integrated address circuit with three PCM states in the PCM signal decoding circuit 110. , provided that the coding numbers of the modified embodiment are the same as those of the transmitter assembly 1.

As shown in Figure 7, a preferred and modified embodiment of the signal receiver assembly 2 in accordance with this invention includes a PCM signal decoding circuit 110, a three-state signal discrimination circuit 120, a signaling circuit trigger 130 and a correction circuit 140. As shown in the drawing, a single integrated address circuit with three states
PCM, IC-MSI, is used, and the control circuit 150 of Figure 5 is also removed without affecting the performance of the preferred embodiment of the signal receiver assembly 2.

 Of course, the present invention is in no way limited to the embodiments described and shown; it is susceptible of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from the spirit of the invention.
