Abstract

Mosquito net (1) in combination with a carrier sheet (6), wherein the mosquito net (1) has a net fabric (5) designed as a canopy for covering a sleeping place and for protecting people from insects; wherein the carrier sheet (6) is made of a flexible material and has an edge region that is attached to the net fabric (5), optionally attached by sewing; wherein the carrier sheet (6) supports a technical functional article, e.g. a water testing kit. In this way, mosquito nets are used as carriers for the distribution of technical functional articles for personal use, the household, the environment, or agriculture in rural areas.

Description

FIELD OF THE INVENTION

The present invention relates to a combination of a mosquito net and a technical functional article attached to the mesh fabric of the net. In particular, it is a combination according to the preamble of the independent device claim. Furthermore, it concerns a method for producing and transporting such a combination, as well as its use.

BACKGROUND OF THE INVENTION

Traditional mosquito nets are the most effective method of protecting people from malaria. In its simplest form, a mosquito net is a mesh panel stretched over a human-occupied space, such as a sleeping area for the night. Effectiveness against mosquitoes and other insects was achieved by adding insecticides to the nets. Technologies in this area have advanced so much in the last two decades that long-lasting insecticidal nets (LLINs) are available, which last for several years despite washing. Accordingly, people keep their nets for long periods of time, and when they move from place to place, whether due to drought or war, the mosquito net is usually one of the items they always take with them, primarily because of its importance as protection against vector-borne diseases and the nuisance of biting insects, but also because of its light weight and bulk, which facilitates transport.

In addition to technological advances, distribution channels for the nets have also improved significantly, making insecticidal bed nets widely available in rural areas, particularly in Africa. Distribution channels for bed nets were used to distribute water filters in a 2008 campaign by Vestergaard, which packaged bed nets, specifically the Perma-Net® type, in CarePack® bags containing a LifeStraw® water filter, condoms, and educational materials to expand the fight against malaria and other vector-borne diseases to include AIDS and other sexually transmitted diseases. Although this campaign was a success, it did not last long, nor was it transformed into a general distribution program for other disease prevention measures.

While distribution channels for mosquito nets are efficient and well-organized, even in the most rural areas of Africa where infrastructure is scarce, few other goods are distributed with such efficiency. Building such infrastructure for other specialized goods is a challenging project, as the required investments are typically high and the return on investment is by no means guaranteed. However, it would be desirable to create similar distribution channels for other goods, especially low-cost goods that can facilitate and improve life in such rural areas.

DESCRIPTION / SUMMARY OF THE INVENTION

It is therefore an object of the invention to provide a general improvement in the prior art. In particular, it is an aim to provide efficient distribution channels for articles in rural areas in order to improve people's lives. This aim and further advantages are achieved with a method and a combination, as well as the use thereof, as described below and in the claims.

In short, mosquito nets are used as a means of distributing technical functional items for personal, household, environmental, or agricultural use in rural areas. The following have proven particularly useful.

When a mosquito net is transported from the production site to an end user, for example, in a rural area in a remote location in Africa, the mosquito net can be used as a means of transport for other technical functional items.

The term "technical functional object" is used for objects that, when used, have a technical purpose and function, in particular a response to a stimulus, e.g., a physical and/or chemical reaction result. In some embodiments, the nature of the technical effect is in human, environmental, or agricultural testing and analysis.

For example, the technical functional object comprises a physical and/or chemical analysis test of a test sample, e.g., of drinking water, food, or agricultural soil, and is intended to display an analytical test result of a test sample to a user. However, electronic technical functional objects can also be transported, either as a test kit or alternatively to bring other types of added value into the user's life.

In particular, the analytical test aims not to be a medical-diagnostic test, but to focus on other areas of life in rural areas.

The use of mosquito nets as a means of transport for the technical functional object avoids the use of additional packaging material, especially plastic bags and boxes, for the distribution of the objects, which is very beneficial in terms of global waste prevention, especially the reduction of plastic waste, as resources and costs are saved and waste materials, especially plastic waste, are reduced.

For the use of the mosquito net as a means of transport for the transport of such technical functional items to rural areas, in particular technical functional items serving as agricultural or environmental test systems, the technical functional item is provided on a thin, flexible carrier sheet, typically made of fabric or film, which serves as a carrier for the storage of the technical functional item during transport to the end-user's location and which may also contain the necessary instructions for the use of the item and information for the evaluation of the test results.

The carrier cloth is attached to the mesh of the net. Typically, only an edge of the carrier cloth, not the entire edge surrounding the carrier cloth, is attached to the net, e.g., by sewing, similar to the usual attachment method for an information label. The carrier cloth is thus similar to information labels, which are typically attached to the mesh by one of their edges to provide information about the net and the provider. Similar to such an information label, the carrier cloth is much smaller than the mosquito net; in particular, it is at least an order of magnitude smaller than the dimensions of the mesh itself. Overall, the carrier cloth has similar dimensions and typically a similar shape to the information label attached to the mesh and differs from these in that it encloses a technical utility item, for example, a test kit for water quality or soil analysis. The technical functional item is thus firmly attached to the net by the carrier cloth and follows the net from the manufacturer to the end user, without the risk of the technical functional item becoming lost during its journey. A further advantage is achieved by the fact that the technical functional object does not have to be packaged separately from the mosquito net.

A further advantage is achieved by attaching the carrier sheet to the mesh of the mosquito net, then wrapping the mesh around the carrier sheet and the technical functional item. In this way, the mesh acts as a cushion, absorbs shock, and forms a temperature-insulating layer around the technical functional item. The combination of mosquito net and carrier sheet, along with the technical functional item, is then packaged and securely shipped from the production facility to the end user.

More specifically, a mosquito net consists of a mesh fabric typically shaped like a canopy to cover a sleeping area and protect people from insects. Such a canopy measures approximately two or three meters in length from the top of the mosquito net to the bottom edge when hung. The support fabric is much smaller, for example, in the range of 10-30 cm in length and width.

As already mentioned, the carrier fabric that supports the technical functional item is made of a flexible material, typically fabric or film. It has an edge area that is connected to the mesh, possibly by sewing, but can also be glued or plastic-welded, the latter being possible with thermoplastic materials such as polyethylene or polypropylene.

• - Test zur Analyse der Wasserqualität;
• - Bodenuntersuchung in der Landwirtschaft,
• - Lebensmitteltest zum Aufspüren von Vergiftungsstoffen;
• - Test auf giftige Gase in der Umwelt;
• - pH-Test.

The invention is suitable for a variety of technical functional objects that are not medical diagnostic objects. For example, the technical functional object can be at least one of the listed objects, for example, as a test kit for:

• - Water quality analysis test;
• - Soil testing in agriculture,
• - Food testing to detect toxic substances;
• - Test for toxic gases in the environment;
• - pH test.

Examples of substances that can be detected with the test kit are ammonia, bromine, chlorine, nitrates, nitrites, phosphates, fluorides, sulfites, and/or metals, e.g., lead, cadmium, manganese, mercury, copper, chromium, or thallium. For example, liquid samples are used, possibly liquid samples obtained by dispersing soil or food samples in liquid. ities, such as water. Other analysis kits are available for some toxins, such as cyanide, azide, chromate, and arsenic. Some test kits are designed to detect mycotoxins, as these are harmful and pose a significant problem in grain storage.

For example, a liquid sample is applied to a test surface after the test surface has been exposed, e.g., by peeling off a thin protective film. After the sample is applied and after a certain predetermined reaction time, the test result is displayed.

In some embodiments, the technical functional article is an analysis kit for indicating the concentration of harmful gases, e.g., radon, ozone, or carbon monoxide. Advantageously, the test reagent is protected in a hermetic cover that, when removed, allows the gases to come into contact with the reagent, which then provides an indication of the presence of the gases when present in a significant concentration, e.g., by indicating a concentration on a scale or by indicating a number or symbol.

For example, the carrier cloth contains a reagent container containing a test reagent, which the user mixes with a liquid or solid substance, such as water, to test the water quality. For example, potential drinking or food samples can be tested to determine if there are any quality issues. Other examples include agricultural samples, such as soil, for testing the agricultural sample for specific substances, possibly pathogens, or nutrient concentrations.

In some embodiments, mixing causes the appearance of the test sample and reagent mixture to change depending on the test result, which may be positive or negative or indicate a concentration level. For example, the mixture changes color or darkness, indicating whether the reagent reacted positively or negatively with the sample.

In other embodiments, the sample liquid, e.g., water, is applied to a planar tubular array, wherein the sample liquid, with or without mixing with a reagent prior to application to the tubular array, passes through the tubular array and causes reactions with an analytical result visible to the user, e.g., by coloration, possibly caused by a selective chemical reaction.

If the test is to determine the concentration of a specific substance, such as a nutrient or a toxin, the color change may be gradual depending on the substance concentration. To assist the user in assessing such a change, the carrier sheet may contain a comparison indicator that represents possible colors and/or shades. This allows the user to directly compare the color or darkness of the reagent and test sample mixture with the indicator and, through this comparison, determine the test result.

Typically, the reference indicator, reflecting the reaction of the reagent with the sample fluid, is sufficiently clear for the user to visually interpret the result. However, it is also possible to increase analytical precision by using a smartphone application that compares the test result with the reference indicator on the carrier sheet. Alternatively, or additionally, the smartphone application can contain a programmed reference indicator for test evaluation and can be programmed with a feedback function to display the result to the user.

For better comparability and correct evaluation, in some cases an applicator field with a test evaluation area is attached to the carrier sheet, onto which the sample is applied after reaction with the reagent and where the color or transparency changes are compared with the comparison indicator so that the user can determine the test result of the test analysis.

Optionally, the applicator pad is equipped with a reagent that provides the user with an indication when applying the liquid sample, whether with or without reagent from a reagent container. In this case, too, the comparison indicator on the side of the applicator pad is a great help for the user to correctly assess the test result.

In some embodiments, the carrier sheet carries a removable test strip for analysis. The strip is configured to display an analytical test result after exposure to sample fluid, such as water. Also in this case, it is advantageous to have a comparison indicator on the carrier sheet so that the user can evaluate the test result on the detached strip by comparing it with the comparison indicator on the carrier sheet, with the strip and carrier sheet arranged side by side.

An example is a pH test strip, whose color changes indicate whether a liquid, such as water, is acidic or alkaline, and which can also indicate the degree of acidity in the pH value.

In some embodiments, a smartphone with a corresponding application, also called an APP, programmed into the smartphone's computer is used as an option for the precise evaluation of color changes or intensity fluctuations for analytical tests. Optionally, the data is exchanged wirelessly via an internet cloud system. For evaluation, the field of view of the smartphone's built-in camera is directed toward the test evaluation area, and the captured image is evaluated, either by the app itself or by transmitting the captured image via the internet and an appropriately programmed server system.

To resemble a carrier cloth, only the edge region of the flexible carrier cloth is connected to the mesh fabric, e.g., by sewing, with the edge section being shorter than the entire edge around the circumference of the carrier. In some embodiments, it is advantageous for the carrier cloth to be removable from the mesh fabric. For this purpose, a release line is provided, e.g., by a perforation in the cloth material of the carrier cloth, e.g., parallel along the attached edge section of the carrier cloth.

The invention is particularly useful for analysis kits for agricultural and/or environmental control.

Other potentially useful technical functional items are thermometers and humidity sensors.

Various sensors can be combined as an option.

In some embodiments for analysis, the carrier sheet comprises electronics that can optionally be used for analysis. One option is electronics printed onto the carrier sheet. For example, the electronics comprise a sensor for analyzing sample liquids, optionally after they have been mixed with reagents, particularly analytical reagents. The electronics comprise, for example, a conductivity detector that displays ion concentrations.

• - Sender oder Empfänger oder Transceiver für elektromagnetische Wellen, mit analogem oder digitale Informationen, zum Beispiel Radiowellen oder Bluetooth-Signale.

In some embodiments, the technical functional object is an electronic object selected from, for example, the following elements:

• - Solar cell to provide electrical power;
• - a battery for storing and discharging electrical energy;
• - speakers;
• - microphone;
• - a light transmitter;
• - a light detector, for example a camera;
• - a computer unit;

• - NFC tag (near field communication);
• - motion sensors;
• - light source;
• - Indoor pollutant detector;
• - Transmitter or receiver or transceiver for electromagnetic waves, with analog or digital information, for example radio waves or Bluetooth signals.

For example, the light transmitter and light receiver, optionally the camera, in combination with the computer unit powered by the battery charged by the photovoltaic cell, are used to evaluate a test specimen on a test surface. The test specimen is illuminated with the light, for example, and the reflected light is captured by the light detector. The signals are evaluated by the computer, resulting in an electronically evaluated analytical test result. Optionally, the loudspeaker is used to inform the user, which is advantageous for illiterate or visually impaired users.

The analysis detector includes, for example, microarrays of light detectors or a camera to measure the density, color, or transmittance of the sample liquid, which is optionally mixed with reagents. One example is the turbidity of water, as well as a spatially resolved color analysis, for example, to assess whether there are worms or similar types of microorganisms in the water, such as harmful protozoa. The electronics can provide the user with feedback on the measurement results. To supply the electronics with electrical power, a flat battery, e.g., one printed on the carrier cloth, can be carried by the carrier cloth, and optionally a flexible photovoltaic cell that powers the electronics on the carrier cloth. and such an optional battery for use in sample analysis.

In this case, it is advantageous if the carrier cloth with the electronics located thereon, e.g. printed on the material of the carrier cloth, is detachable from the mesh fabric, e.g. by tearing along a perforated detachment line in order to detach a functional part of the carrier cloth from a remaining part that remains attached to the mesh fabric.

Regarding electronics, it is noted that recent electronic development has made great strides in electronics with thin, flat and flexible features, even in screens and push buttons for easy communication.

In some useful embodiments, the electronics include a speaker for instructions and feedback, which is useful for communication with illiterate and blind or otherwise visually impaired people. A microphone can be used for dialogue with the user.

In some embodiments, a smartphone is used as an additional tool, for example, to provide the user with additional information. Another possibility is a smartphone as a communication link between the electronics in the network and a remote server or remote personnel for communication with the remote personnel, who can be reached via a radio link or a wireless data transmission connection.

The actions of the smartphone or other reader can be triggered by various trigger mechanisms on the carrier cloth, such as QR codes, barcodes, printed internet links or holographic tamper-evident labels or even RFID (Radio Frequency Identification) tags or NFC (Near-Field-Communication) tags on the carrier cloth.

The trigger mechanism serves, for example, to transmit trigger information to a reader, optionally a smartphone. In the latter case, the smartphone can be programmed with a computer application, a so-called app, that responds to the trigger mechanism and possibly also to user input and/or input from an external server or person. In some embodiments, the app is required to read information from the trigger mechanism, thus minimizing the risk of fraud.

Optionally, the smartphone or other type of reader can respond to the tag reading, for example, by displaying certain information to the user and possibly prompting for input. It's worth mentioning that augmented reality is an option for user communication. The smartphone can also initiate wireless communication with a central server and trigger additional actions. These various options can also be combined.

The above-mentioned technologies can be used, for example, in education, health, agriculture, and for net-related applications, including information sharing, anti-counterfeiting, and determining the durability of the net and its insecticide. Options to increase user comfort include scent dispensers on the carrier sheet or air disinfectants, which are advantageously released slowly over a long period of time, e.g., several months or even a year.

Other options include disinfectants and water purifiers.

An additional insecticide or synergist is another option for a dispenser on the carrier sheet. Even if the net already contains an insecticide, such as a pyrethroid, an additional insecticide or synergist can be provided to enhance the effect, especially in cases of insecticide resistance.

DETAILED DESCRIPTION / PREFERRED VERSION

1 shows a mosquito net 1. The mosquito net 1 has a roof 2 and side walls 3, which in this illustrated embodiment comprise an upper portion 4A and a lower portion 4B of the side walls 3. Such side walls 3 with a lower portion 4B made of a more durable material than the upper portion 4A are found in the insecticidal mosquito net bearing the trademark PermaNet 3.0®, but this is not required for the invention, since the side walls 3 can also be made of one type of material.

Attached to the mesh fabric of the mosquito net 1, usually by sewing, are carrier sheets 6, which are similar to and additional to the labels 6' that are standardly affixed to the mesh fabric 5 of the mosquito net 1 to provide the user with information about the net and the manufacturer. As will become clearer below, the proven principle of labels 6' on mosquito nets 1 can also be used to attach carrier sheets 6 to the mesh fabric 5 in order to distribute technical functional items together with the mosquito net 1. The latter offers a number of significant advantages, which are explained in more detail below.

Typically, such carrier sheets 6 are attached with one of their edges to the lower edge 1A of the mosquito net 1. As an alternative to attaching the carrier sheets 6 to the mesh fabric 5 of the mosquito net 1, the carrier sheets 6 can be attached with their edge to another part of the mosquito net 1, for example by sewing them into the seam 1B between the upper section 4A and the lower section 4B of the side walls 3, which are also in 1 is shown.

Some types of backing sheets 6 are indetachably bonded to the mesh fabric 5 and are intended to remain on the mesh fabric 5, which means that removing the backing sheet 6 by peeling or tearing it off from the mesh fabric 5 would also damage the mesh fabric 5. It should be noted that cutting, e.g., with scissors, is a method for removing part of the backing sheet 6 from the mesh fabric 5, but the sewn part of the backing sheet 6 would remain on the mesh fabric 5, and the backing sheet 6 is not considered removable in the above sense.

Independently, some carrier cloths 6 have sections that are detachable from the mesh fabric 5 and are intended to be removed for use. Such carrier cloths 6 are provided with a separation line 7, typically a perforated line, which is 1 is indicated by a hatched line, from which a part of the carrier cloth 6 is removed from the mesh fabric 5.

As explained in more detail below, such carrier sheets can carry 6 different types of analytical-technical functional parts.

The use of carrier sheets 6, which are dimensioned and handled similarly to conventional information labels, is advantageous in that the technology for handling such carrier sheets and their application to the mesh fabric is similar to that of conventional information labels. Thus, the carrier sheets according to the invention with the technical functional elements can be easily implemented without changing the conventional, efficient production process for mosquito nets, thus keeping additional costs and effort to a minimum. This is an important aspect, since the low prices for mosquito nets 1 must be maintained.

2 shows a carrier cloth 6 carrying a thin thermometer 8, e.g., a printed thermometer. The carrier cloth 6 as a thermometer carrier is attached to the mesh fabric 5, typically by sewing, and the thermometer part is separated by a separation line 7, e.g., a perforation, as indicated by the hatching in 2 indicated, removable from the mesh fabric 5. Once detached, the thermometer 8 can be used to measure the temperature of the environment or of certain liquids or solids, wherein the thermometer 8 indicates the temperature within a specific measuring range. The thermometer 8 is provided, for example, with a series of numbers which, in the present exemplary representation, ranges from 10°C to 50°C, i.e. lies within the range of typical temperatures in homes. The measured temperature is indicated by highlighting the respective temperature number, for example by color, intensity or by a highlighted frame 9 or area around the respective number. One option is the use of thermochromic material.

3 shows a carrier sheet 6, in which a carrier sheet section 6A carries a test strip 10 for an analytical test, e.g., a drinking water test, a food poisoning test, or a test for agricultural soil analysis. The test strip 10 is removable from the carrier sheet 6, for example, by detaching a first carrier sheet portion 6A from a second, remaining carrier sheet portion 6B, as shown, the second carrier sheet portion 6B being attached to the mesh fabric 5. After performing the test with the test strip 10, e.g., by applying drinking water or liquid from food, the user can verify the result by comparing it with a test result comparison indicator 15 for the different result options A, B, C, or D, indicating, for example, a positive test result for two variants of chemicals and/or microbes, a negative test, or an invalid test result. Although the carrier sheet 6 shown shows only a single test strip 10, it can support multiple removable test strips.

4 shows a carrier sheet 6 carrying a reagent container 11 containing a reagent 12. The carrier sheet 6 optionally carries a cotton swab 13, which is encapsulated in plastic for hygienic reasons but not shown here. The cotton swab 13 is used to take, for example, a smear from a food item and then dipped into the reagent 12, which changes its appearance, e.g., its color, depending on a chemical reaction with the food sample, whereupon the final mixture of food sample and reagent 12 is applied to the applicator pad 14, from which the user can derive a test result using a color or intensity scale 15, optionally supported by a fill level indicator 16. To keep the applicator pad 14 usable and free from contamination, it is typically covered with a sealed plastic film for protection purposes, which must be removed to access the applicator pad 14. For illustrative purposes, the cover is not shown here. Optionally, the reference applicator pad 14 can contain another reagent to more clearly demonstrate the test result. For example, reagent 12 in the container tests for microbes, and the second reagent on the applicator pad 14 tests for certain specific chemicals.

5 shows a reagent container 11 with reagent 12 and a point-of-use test kit 17 supported by the carrier sheet 6 and which can be easily detached from the carrier sheet 6. For hygiene reasons and to keep the test kit usable, it will normally be contained in a sealed plastic bag that must be torn open to release the test kit from the carrier sheet 6. For illustrative purposes, the sealed bag is not shown here. For example, the user must place some food or soil into the reagent container 11, which then indicates in its result window 18 whether the test is positive for certain chemicals or microbes.

6 shows a carrier sheet 6 containing visual information 31 for the user to place drops of a liquid sample onto the test evaluation area 30, whereupon reagent is added from one or more reagent containers 11, resulting in some type of reaction visible in the test evaluation area 30.

Alternatively, the reagent is already on the test reading area and only the test sample needs to be provided, typically after removing a cover foil over the test reading area.

7 illustrates a possibility for the precise evaluation of color changes or intensity fluctuations for analytical tests, namely by using a smartphone 22 with a corresponding application, also called an APP, which is programmed in the computer of the smartphone 22. Optionally, the data are exchanged via wireless communication 23 via an Internet cloud system 24. For the evaluation, the field of view 25 of the built-in camera 26 is directed onto the test evaluation area 30, for example onto the carrier cloth 6 of 6 , directed.

8 A time indicator 27 on the carrier sheet 6 indicates a certain passage of time, for example, relating to the estimated lifespan of the insecticide on the mesh fabric 5 or the lifespan of the analysis kit supplied with the mosquito net 1. The time indicator 27 changes its color or color intensity over time, making it clearly visible and easy to interpret for the user.

9 shows a carrier cloth 6 with flexible electronics, e.g., a printed electronic circuit 29 and optionally a photovoltaic cell 28 for powering the electronic circuit 29. Optionally, it can also carry a flexible battery. The electronics are printed, for example, on a flexible substrate attached to the flexible carrier cloth 6 or directly onto a flexible carrier, such as a plastic film, which may be fiber-reinforced for stability reasons. To be able to use the photovoltaic cell 28 separately from the mosquito net 1, the corresponding part of the carrier cloth 6 can be made detachable from the mesh fabric 5 with a separation line 7.

The electronic circuit 29 on the carrier cloth 6 is advantageously used for analytical tests, an example of which is given in 10 which is a cross-sectional view of an electronic circuit 29 used for analytical test analyses. The electronic circuit 29 is electronically connected to a visual detector 33, e.g., a single photodiode for color detection Alternatively, the visual detector 33 can also consist of an array of photodiodes, e.g. in the form of a microcamera, which optionally includes a lens for spatial resolution. The visual detector 33 is configured to detect visual appearances of a test sample 34 that has been applied to a test evaluation area 30 on a coversheet 32, typically after mixing with a reagent. The detection signal of the visual detector 33 is transmitted to the electronic circuit 29. The electronic circuit 29 is advantageously programmed to perform an analysis of the signal of the visual detector 33. This can include, for example, the evaluation of color changes due to a reagent or color intensities or the evaluation of the darkness and/or reflectivity of the test sample.

To facilitate the evaluation of the test sample 34, a light source 35 can optionally be provided, e.g., a light-emitting diode (LED) that emits light at a test-specific wavelength, which is then detected by the visual detector 33 after illuminating the test sample 34. Such a method also enables fluorescence measurements of the test sample 34.

An alternative or additional option is to provide a probe 36 for measuring physical and/or chemical properties of the test sample 34 in the analytical test area 30. For example, the probe 36 is used to measure conductivity. Advantageously, the system consists of a combination of a visual detector 33 and probe 36.

Optionally, the electronic circuit 29 is connected to a visual display 37, e.g., a multi-colored diode, to provide feedback to the user.

As an option, a push button 38 or a keypad is provided with which the user can switch on the electronic circuit 29 for the test and for possible further communication of the user with the electronic circuit 29.

11 shows a dual-parameter warning sheet 40 supported by a carrier sheet. It includes response areas 43A to 43D on the sheet that are reactive in providing information to the user depending on a combination of physical parameters. For example, a warning in one of the areas 43A-43D is displayed to the user in the form of an illuminated or brightly lit information message. The arrows 41, 42 illustrate the increasing level of the two parameters, but the arrows are not typically displayed on the warning sheet 40.

For example, the various response zones 43A-43D are triggered depending on the current temperature and humidity. In this example, zone 43A represents a low-temperature and low-humidity zone. A warning in this zone, such as illumination or a highlighted information message, could indicate a relatively mosquito-free environment. In contrast, warm and humid conditions could trigger a warning in zone 43D, advising the user that it is important to use the mosquito net whenever possible, as these are high-density mosquito conditions.

All of the carrier cloths 6 described above are made of flexible materials to prevent them from detaching from the mesh fabric 5.
