- the solar spectrum that arrives on the Earth's surface has some frequency bands in which there is little emitted electromagnetic radiation, in the same way as artificial light sources. By analyzing them together, you can find ranges of wavelengths in which there is a low emission of both.
- receptors 3 are preferably used which work by receiving electromagnetic radiation having wavelengths within those ranges, as thus, external light interferences in the receivers 3, which can easily prevent the operation of the system 1, can be greatly reduced.
- wavelengths with the advantage shown are those in the infrared range of about 850 nm to about 940 nm, which also have the characteristic of not being visible to the user.
- the receivers 3 are disposed within the channels 10 and aligned to the emitters 2, so as to exhibit operation less susceptible to interference from external sources, such as sunlight or artificial light, or from emitters 2 whose emitted electromagnetic radiation beams reach receivers 3 not intended for them.
- the channels 10 arranged in the fluid dispenser 9 advantageously reduce interferences in the light intensity readings performed by the receivers 3.
- the emitters 2 may be disposed within channels 10 if of interest, which may make the focus narrower.
- the channels 10 need not necessarily be cylindrical, and may have walls of various shapes for the same purpose, such as scenic or serrated, for example.
- the length of the channels 10 can vary widely, having values within a range of about 1 cm to about 4 cm.
- the channels 10 may comprise walls coated or made of material of low reflectivity or high absorption of the portion of the electromagnetic spectrum being measured by the receiver 3, which contributes to the reduction of interferences caused by external sources or by emitters 2 that reach receivers 3 not intended for them.
- the coating material of the channels 10 may comprise paint or materials with reflectivity below 50% of the portion of the electromagnetic spectrum being measured by the receptors 3.
- the plurality of emitters 2 and receivers 3 is used to identify the height of the container 5.
- the presence of the container in the fluid dispenser 9 at least partially blocks the path of the electromagnetic radiation beams emitted by the plurality of emitters 2 towards the plurality of receivers 3. Accordingly, the reduction or elimination of brightness is detected by the receivers 3.
- the receiver 3 'located in the uppermost position of the dispenser 9, i.e., vertically with respect to the base 7 or along the axis of the height of the container furthest from the base 7 or the receiver 3' located at the position closest to the nozzle dispenser 4 or the top of the chamber 13 which has readings of light intensity within or outside a reference range or detecting a decrease that passes from a reference value of the light intensity incident thereon will determine the approximate height of the container 5, which will be registered by the controller.
- the distance between the receiver 3 'and the base 7 corresponds to the height of the container 5.
- the emitters 2 and receivers 3 may be arranged in one or more columns of emitters 14 and one or more columns of receivers 12.
- the emitters 2 of one column 14 point to the receivers 3 of the other column 12, of so that the trajectories of the emitted electromagnetic radiation beams are preferably parallel to the base 7 of the dispenser 9 and parallel to each other, thus crossing the location intended for the container 5.
- the arrangement of the emitters 2 and receivers 3 in at least two columns 14 and at least two columns 12 is particularly advantageous as it may assist in the detection of transparent containers due to the possible deviation caused by refraction of the electromagnetic radiation beams.
- the deviation of the trajectory of the electromagnetic radiation beams generally decreases the luminous intensity identified by the receivers 3. In order for the deviation to occur, it is necessary that the electromagnetic radiation beam obliquely acts on the surface of the vessel 5.
- system 1 illustrates the system 1 with two columns 14 of emitters 2 and two columns 12 of receivers 3, it is noteworthy that the system 1 can also be realized with one or more columns 14, 12 as well as with the emitters 2 and receptors 3 arranged in different forms, such as, for example, diagonally or diagonally.
- a transmitter 2 has a corresponding receiver 3 to which it is pointed, the transmitter 2 does not necessarily need to be positioned adjacent to other transmitters 2, there may be mixing of transmitters 2 and receivers 3 on a same surface of the chamber 13.
- a hydrophobic or hydrophobic treatment is performed in the fluid dispenser 9 or in the surfaces that isolate the chamber 13 from the emitters (2) and receivers (3), so as to prevent fluid accumulation in the in front of them.
- receptors 3 encapsulated in a material are used which filter out unwanted wavelengths of the electromagnetic spectrum, i.e., at wavelengths different from those emitted by the emitters 2, reducing light interference.
- a material or coating with the same function may be applied to dispenser 9 or to receptors 3.
- Another alternative is to position polarizing filters in dispenser 9 or emitters 2 and receivers 3 to prevent unpolarized light from being picked up by receivers 3, thereby reducing possible interferences.
- the presence sensor 8 comprises emitter pairs 2 and receiver 3 positioned near the base, if only the receivers 3 of the presence sensor 8 perform a light intensity reading below their reference values, the assigned height to the container 5 is zero and the filling process is not started. Thereby, the presence of unwanted elements in the fluid dispenser 9, such as a hand, is prevented from inadvertently triggering the flow of liquid, which allows the visually impaired to grope the base 7 and its markings to find the location intended for the container without risk of starting the filling by mistake.
- the system 1 further comprises a user interface 6 configured to receive a desired percentage of the height of the container 5 to be filled with liquid, for example 0 to 100%.
- the user interface 6 is chosen from a group consisting of: rotary switches (such as a potentiometer), sliders, buttons, touchscreen displays and capacitive sensors.
- user interface 6 may display braille indications.
- the user interface 6 consists of a rotary selector with LEDs on its turn which light up according to the chosen percentage, so to illustrate it, as shown for example by Figure 6.
- the selector can comprise a "tooth" in relief so as to facilitate the perception of its position by touch.
- the controller is electronically connected to the presence sensor 8, the distance sensor 11, the plurality of emitters 2 and receivers 3, the user interface 6 and the fluid dispenser 9.
- controller is configured to:
- determining the height of the container 5 comprises sequentially and individually sequentially connecting and disconnecting each emitter 2 from the plurality of emitters 2 and performing the reading of the light intensity from a receiver 3 corresponding to the connected transmitter 2; determining which was the receiver 3 'located in the topmost position ie vertically with respect to the base 7 or along the axis of the height of the container furthest from the base 7 or closer to the dispensing nozzle 4 or the top of the chamber 13, which has a luminous intensity value within a respective reference range, wherein the height of such receiver 3 is considered to be the height of the vessel 5.
- the individual reference value is determined based on a reading of the value displayed by each receiver 3 for luminous intensity detected when its corresponding transmitter 2 is switched on and the vessel 5 is absent from the fluid dispenser 9. Depending on the method adopted for detecting the height of containers 5, none, part or all other emitters 2 may be connected at the time of reading the value presented by each receiver 3.
- the present invention proposes the use of individual reference values for each receiver 3, which consequently generate individual reference ranges for each receiver 3, in order to solve such a problem without require restricted manufacturing tolerances for the components, which occurs mainly in the measurement of transparent containers because they require the detection of small variations in light intensity.
- the controller may be configured to perform a calibration of the receivers 3, i.e. read the readings or values presented by the receivers 3 and subtract an adequate safety margin from each of them to obtain reference values which determine individual reference ranges and with a safety margin for each receiver 3 automatically.
- Such calibration can be programmed to be done the first time system 1 is started in the event of a manual triggering, which can be done by means of a reset button, for example, or by another interface.
- the reading of the value displayed by each receiver 3 is made while the vessel 5 is absent from the fluid dispenser 9, only its corresponding emitter 2 is on and external light interferences are avoided.
- reading a value below, with a certain margin of safety, of the minimum displayed by a receiver 3 in the total darkness with all emitters 2 erased or of a value above, with a certain margin of safety, of the receiver. value presented by a receiver 3 with its respective transmitter 2 connected and unobstructed may be understood by the controller as a malfunction of the transmitter 2, receiver 3 or system 1.
- determining the height of the container 5 comprises connecting and disconnecting each emitter 2 from among the plurality of emitters 2 and performing the reading of the light intensity from a receiver 3 corresponding to the connected transmitter 3.
- determining the height of the container 5 comprises sequentially and individually switching on and off each emitter 2 from the plurality of emitters 2 and performing the light intensity reading from a receiver 3 corresponding to the connected emitter 3.
- each transmitter 2 avoids possible interference in the reading of the light intensity caused by other transmitters 2, enabling broad emitters 2 that reach more than one receiver to be used.
- the trigger sequence of the emitters may be in a predetermined order or may be random.
- the driving sequence of the emitters 2 may be performed without prejudice by connecting more than one emitter 2 at a time if the emitted electromagnetic radiation beams do not interfere with receivers 3 not intended for them.
- emitters 2 at opposite ends of the column 14 may be connected at the same time, which may also reduce the time required to perform all readings.
- certain types of LEDs can be used with 15 times greater electrical currents if they are connected for less than 100 ps and a minimum time is expected before being switched on again, which makes the electromagnetic radiation incident from other sources a smaller fraction of the total.
- self heating by letting certain transmitters 2 connected half the time instead of continuously, for example, advantages can already be found.
- both the step of connecting emitters 2 for short periods and that of sequentially connecting them may be replaced by modulation forms, drive at a given frequency, or use of pulses to achieve the advantages shown.
- a time interval may be allowed after connecting a given transmitter 2 before its corresponding receiver 3 is read, the time interval corresponding to the stabilization of the intensity of the electromagnetic radiation emitted by at least one respective transmitter 2 or value presented by the receiver 3.
- LDRs Light Dependent Resistors
- the controller is configured to control the flow of liquid into the vessel by means of releasing the liquid stream if the height of liquid in the vessel is less than the desired liquid height and the flow interruption of liquid height in the container is greater than or equal to the desired liquid height.
- the controller is configured to control the flow of liquid into the container by releasing the flow of liquid only if the presence sensor 8 detects the presence or correct positioning of the container 5.
- the stand-alone filler via the user interface 6 or another interface.
- a rotary selector can be used which, when pressed, functions as a stand-alone power switch, for example.
- the presence sensor 8 may have the function of directly switching on and off the liquid flow.
- the controller may further comprise electronic components such as relays, transistors, and solid state relays configured to connect and disconnect components requiring incompatible electrical currents or voltages, such as the drive device, emitters 2 and receivers 3.
- electronic components such as relays, transistors, and solid state relays configured to connect and disconnect components requiring incompatible electrical currents or voltages, such as the drive device, emitters 2 and receivers 3.
- emitters 2 and receivers 3 may be connected only during use of the system 1 or at the time of measuring the height of the container 5. Further, the controller may be configured to turn off transmitters 2 or receivers 3 during part of the filling cycle.
- the controller may further be connected to a multiplexer module to be able to read 3 from several receivers and control various emitters 2.
- the system 1 comprises a sound device connected to the controller and configured to emit a beep in response to performing any procedure related to the filling of the container 5, such as, for example, starting the filling or ending at the filling, i.e. , if the height of liquid in the vessel 5 has become equal to or greater than the height of liquid desired.
- the controller may be further configured to determine the height of liquid in the vessel 5 by means of the mean, which may be arithmetic, geometrical or otherwise, of a plurality of measurements of the distance sensor 11.
- the plurality of measurements may comprise from 2 to 50 measurements.
- the controller may be further configured to request further measurements from the distance sensor 11 if a measurement within one or more measurements is outside a reference standard, for example, if a is greater than the distance from the sensor 11 to the base 7.
- the new measurements may comprise from 1 to 50 measurements.
- the controller may be configured to assign a minimum water height and a safety margin to the top of the vessel.
- the user interface 6 allows the choice of a water height between the minimum height and the height of the container minus the safety margin, which prevents inaccuracies or inaccuracies of the distance sensor 11 from causing overflows.
- the values of the minimum height of the water column and the safety margin of the top of the vessel can be changed according to the manufacturer's preference.
- the controller may be configured to drive and interrupt the flow of liquid to the vessel 5 once per filling cycle, requiring that the next liquid flow drive be performed only after withdrawal and re-receiving or moving of the container 5 in the fluid dispenser 9. In this way, the system 1 is prevented from interleaving between releasing and stopping the flow of liquid due to possible inaccuracies of the sensors.
- the present system 1 is capable of filling without overflowing containers of varied materials, shapes and sizes, as it independently adjusts the amount of liquid to be placed in accordance with the container 5 used.
- emitters 2 with broad electromagnetic radiation beams to the extent of reaching non-corresponding receivers 3 and with lower concentration of light due to the wider focus compared to lasers, for example, such as LEDs is satisfactorily compensated for by For example, by arranging the emitters 2 and receivers 3 on the bottom of ducts 10 coated with low reflectivity material to portions of the electromagnetic spectrum, to turn on and off the emitters 2 sequentially and individually and assign specific reference values for each receiver 3, which improves the consistency of the readings obtained.
- the focus area of the emitter 2 used should be large enough to, despite deviations due to lack of uniformity in the components or system 1, allow its radiation beam electromagnetic wave to reach its corresponding receiver 3 with adequate intensity.
- Such deviations usually do not exceed 2 cm, therefore, foci with areas with diameters greater than 2 cm or with angles of half intensity greater than 3 degrees are usually sufficient to allow operation without a cautious alignment.
- the emitters 2 comprise a half intensity angle between 3 degrees and 90 degrees.
- the bulbs are not so wide, for example having angles of half intensity below 60 degrees.
- the present invention also enables ubiquitous, inexpensive and high-life 2 emitters as infrared LEDs to be used.
- the system 1 does not exclude the possibility of applying traditional filling methods, such as knobs or mechanical sensors, to the dispenser 9 so as to provide the possibility of manually filling a container 5.
- traditional filling methods such as knobs or mechanical sensors
- the present invention may be embodied in analogous ways and may exhibit modifications in its form of implementation, so that the scope of protection of the invention is limited only by the content of the annexed claims, including all possible equivalent variations related to the method and the system.
