    DESCRIPTION
    DEVICE FOR SUPPLYING ELECTRICAL ENERGY TO LIGHTING DEVICES AND LIGHTING SYSTEM INCLUDING THE DEVICE
    Field of the Invention
    The present invention relates to the field of equipment that supplies electricity to light devices and equipment that provides light.
    Background of the invention
    The lighting systems and light devices (that is, emitting light) that form them are necessary to provide, both indoors and open spaces, with enough light to see the surroundings and the objects present. The light must provide sufficient lighting to be able to see clearly and in turn produce comfort for people.
    Recently, a transition has begun to change the more traditional light devices such as fluorescent lamps or incandescent lamps for LED-type light devices, since the latter generally have a longer life and are more energy efficient than other previous light technologies. One of the sectors that LED lighting technology is adopting the most is the means of transport. With regard to the lighting of means of transport such as airplanes or trains, it is necessary to introduce lamps, luminaires or light devices (the terms lamp, luminaire and light devices are used interchangeably in this document) outside the vehicles to be able to have light as in installation and / or maintenance work on them, the vehicle's own light may be inoperative (eg the lamps of a vehicle may not be installed, or the lamps may be disconnected because the electrical system is being worked on , etc.).
    It is important to be able to perform installation and / or maintenance operations with proper lighting so that operators can work with good visual conditions. At present, the lamps used in these operations are electrically powered in parallel, using a source of electric power from the same vehicle and / or external to the vehicle. However, if a short circuit occurs or there is an excess of consumption in any of the lamps, for example the vehicle protection systems could disable the power supply to the entire lighting system, thus leaving the entire vehicle without lighting. In this case, apart from the problem of not having light, there is the problem of being able to identify which luminaire produces the fault, since it cannot be distinguished visually which of all the luminaries it is.
    On the other hand, since several luminaires are necessary to be able to provide sufficient light to much of the passenger compartment of such vehicles, the current that can circulate in total in the luminaire assembly can be high and, therefore, the level of electrical power that Consume is also high. Depending on the configuration, the connection and / or disconnection of the luminaire set can cause safety problems, because when plugging or unplugging the assembly, a voltage arc can be generated that burns some of the vehicle's devices or any of the luminaires , or even cause a fire or damage an operator.
    In the case of using LED-type luminaires, it is also necessary to supply a current with a correct and stable intensity to them so that the luminaires provide adequate light without damaging them; the overcurrents negatively affect the life and operation of the led type lights.
    There is therefore a need in the state of the art for a device capable of supplying electric power to one or more light devices that facilitates the identification of a light device with a fault, that properly supplies power to the light devices, and that it does not entail security risks when they are connected and / or disconnected to the source of electrical energy. There is also a need for a lighting system that is provided with the same or similar characteristics.
    Description of the invention
    The present invention solves the problems described above by means of an electronic device that supplies electric power to one or more light devices connected thereto in a stable and controlled manner in accordance with preferred embodiments of the invention, and by an associated lighting system according to embodiments. Preferred of the invention.
    In a first aspect of the invention a device is presented for supplying electric power to one or more light devices, the device comprising:
    a printed circuit board comprising an electrical circuit;
    a first terminal configured to connect an electric power source that supplies a

    first electrical voltage; Y
    a second terminal configured to connect a first light device;
    The electrical circuit comprises a first voltage output module, the first voltage output module comprising a first DC to DC converter that provides a second electrical voltage at the second terminal when the first electrical voltage is received at the first terminal;
    the first DC to DC converter also detects an overload or a short circuit in the second terminal; Y
    The first DC to DC converter also stops providing the second electrical voltage when it detects the overload or short circuit in the second terminal.
    The device for supplying electric power can be an electronic device such as a control board, or one or more control boards interconnected with each other. The device may include a support on which the printed circuit board (also referred to below as PCB, corresponding to Printed Circuit Board) is arranged or held, as well as a housing or a box in which whose interior resides the printed circuit board (with or without support).
    The device receives, through the first terminal, an electrical voltage from a source of electrical energy outside the device that energizes the electrical circuit of the PCB. The electrical circuit and, therefore, the PCB are electrically connected to the second terminal, to which the first light device can be connected.
    The DC to DC converter of the first voltage output module, which is part of the electrical circuit, energizes the first light device when it is connected to the second terminal while the device receives the electrical voltage at the first terminal. The DC to DC converter also detects if there is an overload or a short circuit in the second terminal (that is, if there is an overload or a short circuit in the first light device connected to the second terminal of the device) and for energization in case of positive detection , thus being able to avoid (apart from unnecessary energy expenditure, as the energy supplied will end up dissipating) overheating in electrical conductors that can cause a fire (eg inside a vehicle where one or more operators are performing maintenance works). That is, the DC to DC converter does not provide the second electrical voltage when it detects the overload or short circuit in the second terminal. The DC to DC converter can monitor the amount of current that is provided at its output and in case the amount of current is below or above an accepted current intensity range, the DC to DC converter can deactivate The voltage output as the reason for the mismatch in the amount of current it provides may be due to an overload or a short circuit in the second terminal.
    In some embodiments, the DC to DC converter provides the second electrical voltage with a constant voltage when the first electrical voltage received is in a range of electrical voltages.
    The DC to DC converter can stabilize the voltage (eg at an output voltage of 24 volts) that supplies the first light device and, therefore, the power and current supplied to it. This output voltage can be provided despite the fact that the first electrical voltage received by the device is not stable, that is, that the level of voltage that energizes the device has fluctuations (eg in a range between 18 V and 36 V ). A voltage dependent on the first electrical voltage received on the device arrives at the input of the DC to DC converter, and an electrical voltage is provided at the output of the DC to DC converter with a voltage level dependent on the voltage level of the first voltage electric The electrical voltage provided is generated in the DC to DC converter so it is not the first received electrical voltage converted to another voltage level; This allows irregularities that may exist in the first electrical voltage not to be transferred to the second electrical voltage. When, for example, LED-type light devices are energized, that is, if a first light device that is a LED luminaire is energized, it is convenient to do so with a current that has a substantially constant intensity so that the level of light provided does not vary (a light with light intensity that varies over time tires the view and does not produce comfort) and that the electronics of the luminaire is not punished. In some embodiments, the DC to DC converter returns to provide the second electrical voltage when, after having stopped providing the second electrical voltage upon detecting the overload or short circuit in the second terminal, it detects that the overload or short circuit in the second terminal It has ceased.
    The DC to DC converter can detect the existence of the overload or short-circuit cyclically every so often and, when it detects that an existing overload or short-circuit has disappeared, it can re-energize the first light device.
    In some embodiments, the electrical circuit further comprises a first timer module that temporarily delays an electrical power supply to power the first voltage output module when reception of the first electrical voltage is initiated or the first light device is connected to the second terminal. In some of these embodiments, the first timer module comprises a plurality of NOT logic gates and a plurality of passive electronic components.

    Since the power to the first voltage output module is delayed, the first DC to DC converter provides the second electrical voltage in the second terminal temporarily delayed with respect to one of the following two instants: when the first supply begins electrical voltage to the device, or when the first light device is connected to the second terminal. This is particularly advantageous to avoid generating current peaks by connecting several light devices (a period of time needs to pass for the current to stabilize), something that can negatively affect electrical conductors (they may not be prepared to withstand currents of very high intensity). Likewise, the current peaks can activate a safety mechanism of a protection system (eg of a vehicle in which maintenance operations are being carried out and where the vehicle is the source of electrical energy that energizes the device) that controls that the current corresponding to the first electrical voltage does not exceed a certain intensity; The safety mechanism can cut off the voltage supply, so that when the device is not energized, no light devices connected to it can be energized. As an example, the time delay provided by the first timer module can be between 0 and 10 seconds, for example 1.5 seconds, 2 seconds, 3 seconds, etc.
    In some embodiments, the electrical circuit further comprises a first cold connection module for the first terminal. In some of these embodiments, the first cold connection module comprises a connection detection terminal of the electrical power source to the first terminal.
    The first cold connection module does not allow current to flow through the electrical circuit until it detects that a correct connection has been made to the first terminal, particularly a connection of the electrical power source; likewise, the first cold connection module for the current flow through the electrical circuit when it detects that a disconnection is occurring in the first terminal. The cold connection avoids the occurrence of voltaic arcs in the immediate vicinity of the device due to the existence of an electric current flowing through the electrical circuit when there is not a good connection in the first terminal, for example during the connection and / or disconnection of the electric power source For this purpose, the first cold connection module verifies that all the pins or legs of the electric power source are connected to the device (eg to the first terminal of the same, or to a connector electrically connected to the first terminal) to close the circuit and allow the flow of current. For example, two pins or legs of the connector of the electric power source can be of control and have a shorter length than the rest of pins or legs, which indicate that the connector is well connected only when there is electrical connectivity (being more short, while the connector is connected or disconnected, these pins are the last to connect to the device or the first to disconnect). Similarly, the first terminal may be provided with similar pins that perform the same function. In both cases, the connection detection terminal detects that there is electrical connectivity to open or close the electrical circuit.
    In some embodiments, the device further comprises one or more fans; The electrical circuit also comprises a regulation module of the one or more fans; and the first timer module also activates the one or more fans through the regulation module.
    The one or more fans can help dissipate the heat that dissipates the device and the PCB. The regulation module allows adjusting the speed of the one or more fans in order to adapt the cooling capacity to the heat that may be generated in the device.
    In some embodiments, the device further comprises a third terminal configured to connect a second light device; The electrical circuit also comprises a second voltage output module, the second voltage output module comprising a second DC to DC converter that provides a third electrical voltage at the third terminal when the first electrical voltage is received; the second DC to DC converter also detects an overload or a short circuit in the third terminal; and the second DC to DC converter also stops providing the third electrical voltage when it detects the overload or short circuit in the third terminal.
    The device can energize a second light device even while energizing the first light device.
    In some embodiments, the second DC to DC converter provides the third electrical voltage with a constant voltage when the first electrical voltage received is in the range of electrical voltages.
    In some embodiments, the second DC to DC converter returns to provide the third electrical voltage when, after having stopped providing the third electrical voltage upon detecting the overload or short circuit in the third terminal, it detects that the overload or short circuit in the third terminal has stopped.
    The second DC to DC converter can function similarly to the one described above in relation to the first DC to DC converter.

    In some embodiments, the second DC to DC converter provides the third electrical voltage with a power different from a power with which the first DC to DC converter provides the second electrical voltage.
    The device can provide different electrical voltages with different power to energize the first and second light devices, for example it can provide voltages of 24 V in each of the second and third terminals but with different current intensities such as 3 amps and 500 milliamps, respectively.
    In a second aspect of the invention a lighting system is presented comprising:
    a first device for supplying electricity to light devices according to the first aspect of the invention; Y
    a first light device connected to the first device.
    The lighting system can correctly energize the first light device so that the light it provides is stable, that is, without fluctuations in light intensity. The system is protected against faults such as overloads or short circuits that may occur in the first light device, as well as against arcs that can be generated during the connection and / or disconnection of the first light device to the device.
    The lighting system can be a maintenance equipment that can be conveniently used, for example, in installation and maintenance operations in rooms or rooms such as the interior of a vehicle such as an airplane or a train.
    In some embodiments, the system further comprises:
    a second device for supplying electricity to light devices according to the first aspect of the invention; Y
    a second light device connected to the second device.
    The lighting system can correctly energize both light devices, including each with a different power.
    In some embodiments, each light device (ie, the first light device; or the first light device and the second light device) comprises a tube of plastic material, preferably polyvinyl or polymethylmethacrylate (eg plexiglass); and the tube includes inside:
    a metallic element comprising a metallic tube or a metallic strip; and a plurality of LED strips attached to the metal element.
    The light devices can be comfortable to handle or carry by a user thanks to its structure. The polyvinyl or polymethylmethacrylate tube lets in the light provided by the plurality of LED strips inside it and, in turn, allows it to be seized by not transferring excessive heat to it, since the heat dissipated by the LEDs maintains, to a large extent, the metallic element.
    When the tube is made of polyvinyl, the tube can also allow it to be arched or even bent during handling due to its flexibility; In some of these embodiments, the polyvinyl tube further comprises silicone inside the tube (silicone that fills the tube), which increases the flexibility and strength of the tube. When the tube is made of polymethylmethacrylate (eg plexiglass), the tube is rigid. Depending on the application, the choice in the material of the tube can facilitate the performance of installation and maintenance operations in rooms or rooms such as the interior of a vehicle such as an airplane or a train, because in some cases flexible lighting devices may be more convenient , while in other cases rigid lighting devices may be more convenient.
    In some embodiments, in each light device, the plurality of LED strips comprises a first LED strip disposed on a first face of the metal element, and a second LED strip disposed on one face of the metal element opposite the first face.
    The lighting devices can provide light in two opposite directions by placing a LED strip on one face of the metal element and another LED strip on an opposite face of the metal element. This allows operators who work, for example, in a low area (eg at ground level) to have light and other operators who work, for example, in a high and nearby area also have light. Or that if the system is located, for example, in the aisle of an airplane cabin, the light devices can provide light towards a set of seats on one side of the aisle and towards a set of seats on the other side of the aisle.
    In some embodiments, the system further comprises at least one connector configured to connect another lighting system and supply electrical power to the other lighting system, in which the other lighting system at least comprises:

    a device according to the first aspect of the invention and a light device connected to the device.
    The lighting system, in addition to providing light, can also supply electric power to similar or identical systems by being able to cascade these to it. That is, the lighting system can energize light devices that provide light as well as energize other systems that in turn also provide light. This allows the system to be modular and several cascade lighting systems can be joined together to enable lighting of a large or long space (eg a train car, an airplane cabin, etc.) .
    Advantages similar to those described with respect to the device of the first aspect of the invention may also be applicable to the system of the second aspect of the invention.
    These and other advantages of the invention will be apparent in light of the detailed description thereof.

    Description of an embodiment of the invention
    Figure 1 shows a device 101 capable of supplying electrical energy to light devices according to an embodiment. The device 101 comprises a first terminal 111 configured to connect an electrical power source (not illustrated) that supplies a first electrical voltage, and a second terminal 112 configured to connect a light device (not illustrated). The device 101 further comprises a printed circuit board (not illustrated) that includes a voltage output module 121 (in an electrical circuit comprised in the PCB).
    The voltage output module 121 is electrically connected to the first and second terminals 111, 112, and is configured to provide a second electrical voltage at the second terminal 112 with which it can energize a light device that connects to the second terminal 112. When The device 101 receives the first electrical voltage at the first terminal 111, the device 101 electrically feeds the voltage output module 121, which provides the second electrical voltage.
    The voltage output module 121 is further configured to detect if an overload or a short circuit occurs in the second terminal 112 and, in the event of such an event, it is also configured to stop providing the second electrical voltage in the second terminal 112 By cutting off the supply to the second terminal 112, the device 101 prevents overheating in the electrical conductors both external to the device 101 and internal to it (due to the circulation of electric current) thus decreasing the likelihood of a fire.

    Figure 2 shows a device 102 capable of supplying electrical energy to light devices according to an embodiment. The device 102 comprises the first terminal 111, the second terminal 112, the voltage output module 121, and a timer module 131 (on a PCB comprising an electrical circuit, not shown). The timer module 131 is electrically connected to the first terminal 111 and the voltage output module 121; and the voltage output module 121 is electrically connected to the second terminal 112.
    When electrical power supply is received at the first terminal 111, that is, when the first electrical voltage is received from a power source, timer module 131. is energized. Timer module 131 is configured to energize the voltage output module. 121 with a certain time delay with respect to the moment in which the reception of the first electrical voltage was initiated in the first terminal 111, and / or with respect to the moment in which a light device is connected in the second terminal 112. At delaying the power supply of the voltage output module 121, the power to other devices connected to the device 102 is also delayed, so that several cascaded devices can be prevented from turning on simultaneously, which would generate current peaks capable of damaging the used electrical conductors and / or one or more devices. The system or the source that provides the first electrical voltage at the first terminal 111 may be provided with protection systems to prevent this from happening, however the protection mechanisms that are usually employed consist of cutting off the energy supply, so that It would be possible to give birth.
    Figure 3 shows a device 103 capable of supplying electrical energy to light devices according to an embodiment. The device 103 comprises the first terminal 111, the second terminal 112, the voltage output module 121, the timer module 131, and a cold connection module 141 (on a PCB comprising an electrical circuit, not shown). The cold connection module 141 is electrically connected to the first terminal 111 and to the timer module 131, which in turn is electrically connected to the voltage output module 121; the voltage output module 121 is electrically connected to the second terminal 112.
    The cold connection module 141 is configured to keep the electrical circuit open until an electrical power source is properly connected in the first terminal 111. Also, the electrical circuit being closed while the device 103 is operating, the connection module in Cold 141 is also configured to open the electrical circuit when the electrical power source begins to be disconnected (but disconnection has not yet been completed). By not circulating current through the electrical circuit until the cold connection module 141 allows it (only when there is a good connection between the device 103 and a source of electrical energy in the first terminal 111), it is avoided that voltaic arcs occur between the device 103 and the power source that could damage both the device 103 and the power source as well as any other device connected to one of both. Another of the risks of voltaic arcs is that they can reach and injure a person, something that can be avoided with the cold connection module 141.
    Figure 4 shows a device 104 capable of supplying electrical energy to light devices according to one embodiment. The device 104 comprises the first terminal 111, the second terminal 112, the voltage output module 121, the timer module 131, the cold connection module 141, a power module 151 and a regulation module 161 (on a PCB comprising an electric circuit, not illustrated) of one or more fans that the device 104 also comprises (not illustrated). The different modules of the device 104 are electrically connected in a similar way to the device 103. The timer module 131 is also electrically connected to the power module 151 and the regulation module 161. The power module 151 is electrically connected to the second terminal 112 in the same way. than the voltage output module 121.
    The device 104 further comprises switching means (not illustrated) that allow selectively switching (illustrated with broken lines) between the voltage output module 121 and the power module 151. Thus, the timer module 131 energizes the voltage output module 121 or the power module 151, and the one that is energized of these two is the one that is electrically coupled to the second terminal 112 to provide the electrical voltage to the device that is connected to the second terminal 112. The power module 151 is configured to providing an electrical voltage with a power greater than the voltage output module 121, which allows the device 104 to be adapted to the device or devices that are connected in the second terminal 112.
    The same device can provide a power supply for powering other devices that may not be light, for example. In this regard, the device may comprise an additional terminal configured to connect an additional power source, for example a power source, that energizes the active electronic components of the first power module. The switching means make it possible to selectively select whether the first power module or the first voltage output module should provide an electrical supply in the second terminal.

    With an embodiment. The device 105 comprises the first terminal 111, a second terminal 112 configured to connect a first light device (not shown), a third terminal 113 configured to connect a second light device (not shown), a first voltage output module 121, a second voltage output module 122, a first timer module 131, a second timer module 132, a first cold connection module 141 and a second cold connection module 142 (on a PCB comprising an electrical circuit, not illustrated ). The first cold connection module 141 is electrically connected to the first terminal 111 and the first timer module 131; the first timer module 131 is electrically connected to the first voltage output module 121; and the first voltage output module 121 is electrically connected to the second terminal 112. The second cold connection module 142 is electrically connected to the first terminal 111 and the second timer module 132; the second timer module 132 is electrically connected to the second voltage output module 122; and the second voltage output module 122 is electrically connected to the third terminal 113.
    When the device 105 receives a first electrical voltage at the first terminal 111 (from an electrical power source), it can provide a second electrical voltage at the second terminal 112, and / or a third electrical voltage at the third terminal 113. This mode can energize two light devices connected to two second and third terminals 112, 113. The powers (or, equivalently, the intensity of the currents) of the second and third electrical voltages can be different, therefore different types of devices luminaires can work thanks to device 105.
    Figure 6 illustrates an electrical circuit 200 suitable for a device for supplying electrical energy to light devices according to an embodiment. The electrical circuit 200 includes a voltage output module 201, a timer module 202, a cold connection module 203, a power module 204, a regulator module 205 for controlling one or more fans connected to the terminal or port 213.
    The cold connection module 203 is electrically connected to the first terminal or port 211 where an electrical power source can be connected to receive, in the electrical circuit 200, a first electrical voltage. The device that includes the electrical circuit 200 may include, in the cold connection module 203, a visual indicator (LE3) of the LED type indicating whether a device is connected to the first terminal or port 211 correctly (i.e., the visual indicator turns on if the cold connection module 203 closes the circuit).
    A high or low voltage of the cold connection module 203 arrives at the timer module 202 to energize the rest of the electrical circuit 200. The first logic gate NOT (U3.3) reverses the voltage, and the second logic gate NOT (U3.2 ) will have a low or high voltage at its input depending on the output of the NOT logic gate (U3.3) and the status of a parallel capacitor (C1), which takes time to charge. The charging time of the capacitor (C1) is part of the time delay introduced by the timer module 202. Likewise, the third NOT logic gate (U3.1) reverses the low or high voltage at its input, which is conditioned by the voltage from the output of the second logic gate NOT (U3.2) and the state of a parallel capacitor (C2), which will also be charged depending on the current that exists and, therefore, will also introduce a temporary delay.
    The timer module 202 energizes the voltage output module 201 or the power module 204, which can be selected with switching means such as, for example but without limitation, the activation or deactivation of an integrated circuit U2 or a transistor Q2 . In some embodiments, thanks to the modularity of the electrical circuit, it is only provided with a voltage output module 201 or a power module 204, since depending on the type of application of the device it may not be necessary to have both modules.
    The voltage output module 201 is connected to a second terminal or port 212 where a second electrical voltage originated from the voltage output module 201 is provided. In this embodiment, the voltage output module 201 includes the integrated circuit U2 which It comprises a DC to DC converter. The DC to DC converter receives a voltage at an input terminal or port thereof, and provides a voltage at an output terminal or port thereof. The voltage that the DC to DC converter provides depends on the level of voltage that reaches the electrical circuit 200 through the first terminal or port 211, however it is a voltage that occurs in the converter itself so that any irregularity that may exist in The first electrical voltage does not appear in the electrical voltage generated by the converter. The DC to DC converter can provide a stable and constant electrical voltage (eg 24 V) even if the first electrical voltage fluctuates, the first electrical voltage being, for example, in a range of electrical voltages between 18 V and 36 V. The DC to DC converter can also detect if there is an overload or a short circuit in the second terminal 212 based on measuring the amount of current that the DC to DC converter supplies, as a value outside a window that is preset in the DC to DC converter indicates such event; that is, if the measured current has an intensity above a maximum threshold or below a minimum threshold, the existence of a possible overload or short circuit is determined. In addition, a visual indicator (LE4) can be provided to show if the second electrical voltage is being provided to the second terminal or port 212.
    The power output module 204 allows to provide a high power power supply in the second terminal or port 212 (illustrated as TP1 and different from J3 only for illustrative reasons, however

    Figure 12 illustrates a cascade connection of a plurality of lighting systems according to one embodiment. In Figure 12 two lighting systems 410 are shown, each comprising a first and second light devices 411, 412. The two lighting systems 410 are cascaded by means of electrical conductors 402.
    One of the lighting systems 410 is connected to a magnetothermal and differential electrical protection device 400. The electrical protection device 400 is connected to an electric power source (not illustrated) by means of an electric conductor 401. Therefore, from the electric power source an electrical voltage is provided to the first lighting system 410 through the device of electrical protection 400, and this first lighting system 410 provides an electrical voltage to the next lighting system 410.
    The electrical conductors 401, 402 are illustrated with a union of two electrical outputs. For example, in aviation environments, it is common for inputs and outputs to be provided for different types of food; an electric power source can provide an output for lighting (eg with a voltage of 240 V), and another output for service (eg with a voltage of 240 V). In other embodiments, the electrical conductors 401, 402 are connected to a single output and, therefore, do not have a connection of two electrical outputs.
    Figure 13 partially illustrates a cabin 500 of an airplane with a plurality of lighting systems 410 according to one embodiment, where the lighting systems 410 are cascaded. Each lighting system 410 comprises two light devices 413 (in other embodiments, a lighting system may comprise a single light device). The lighting systems 410 are connected to each other, and one of them is connected to an electric power source 501 of the aircraft itself to provide an electric voltage to the different lighting systems 410. The electric power source 501 may be provided with a electrical protection device (not illustrated) similar to device 400 of Figure 12.
    By cascading, the plurality of lighting systems 410 can illuminate a large space such as the cabin 500 of the aircraft. The lighting systems 410 give flexibility to the operators who must perform maintenance operations on the aircraft by allowing, in a modular way, to connect and disconnect the lighting systems 410 according to the light needs of the operators. By connecting the plurality of lighting systems 410 to the electric power source 501, the timer modules thereof cause the lighting of the light devices 413 to be carried out in a progressive manner, thus preventing a lighting of all the light devices 413 practically in the same instant, which would cause an overcurrent capable of damaging the lighting systems 410 or some aircraft device.
    As is apparent to the person skilled in the art, the electrical connections between different modules, electronic components and / or devices can be direct (i.e., without other modules, electronic components and / or devices in between) or indirect (i.e. with other modules, electronic components and / or devices in between) unless otherwise indicated.
    Despite having used the terms first, second, third, etc. in the present text to describe different magnitudes, components, devices and / or systems, it should be understood that the magnitudes, components, devices and / or systems should not be limited by these terms because they are only used to distinguish a magnitude, component , device and / or other's system.
