Description

The present invention relates to a piece of clothing which is suitable for reducing the risk of transmission of pathogens between people in everyday life.

A number of factors determine the risk of transmission of pathogens such as viruses and bacteria between people.

Various measures for reducing the risk of transmission of pathogens have become known from the prior art.

Above all, rules of conduct have become known, especially under the abbreviation AHA - distance-hygiene-everyday mask. In addition to increased hygiene through increased hand washing, people should also ensure that they keep a sufficient distance from other people. Everyday masks or so-called surgical masks or FFP2 or FFP3 masks also help to reduce the risk of infection.

In order to reduce the risk of infection, markings, e.g. in the form of stickers on the floor, are used at checkout areas in supermarkets and the like to make it easier to maintain safety distances. To reduce the risk of infection, mechanical barriers have also become known, which are intended to prevent a direct exchange of respiratory air and droplet infection, e.g. also in fast food.

A certain disadvantage here is that the markings and barriers serve as an aid for the user of the code of conduct, but the user of the code of conduct still has to pay attention to whether they are actually being observed for themselves depending on the current circumstances.

Face masks have also become known, the nature of which is such that viruses are automatically killed or inactivated on the surface or when they pass through the tissue. Such face masks can fundamentally reduce the risk of transmission of pathogens considerably. The disadvantage of this, however, is usually that the resistance to the passage of breathing air is significantly increased, making breathing more difficult. In addition, such masks do not always fit perfectly on the user's face, so that a not inconsiderable proportion of unfiltered air can be inhaled. While such masks help to reduce the risk of transmission of pathogens, they cannot always avoid the risk of infection.

The federal government's Corona warning app has also become known, which uses the strength of Bluetooth signals to determine distances to other users. Encrypted and anonymous codes are stored, whereby the duration of the contact is also taken into account. If a contact person is infected and tests positive, you can receive a message that you had a high-risk or low-risk encounter. The disadvantage is that one does not find out how close the contact persons were and when and where and with whom the contact took place. Technically, the system works in such a way that the smartphones of different users communicate with each other via radio. Based on this or similar technologies, there are also systems in which Bluetooth-equipped devices give their users feedback on the risk of transmission. The disadvantage here, too, is that in principle everyone has to be equipped with a functioning device. This is why these solutions do not lead to reliable protection either. The Corona-Warn-App notifies the user of a risk even days after contact.

It is therefore the object of the present invention to provide a garment which makes it possible to reduce the risk of transmission of pathogens in everyday life.

The object is achieved by a garment having the features of claim 1. Preferred developments of the invention are the subject matter of the dependent claims. Further advantages and features of the present invention result from the general description and description of the exemplary embodiments.

A piece of clothing according to the invention, in particular for reducing the risk of transmission of pathogens, comprises at least one clothing element that is in particular flat in design. the dress tion element is preferably at least partially flexibly formable and portable on a user's body. Furthermore, the item of clothing comprises at least one measuring device for determining the distance between a user and the environment and in particular at least one other person. So e.g. B. distances to other people can be determined in everyday life. The measuring device is at least partially accommodated on the clothing element and can in particular also be attached to it.

The invention has many advantages. The garment can be easily integrated into everyday life. The user can simply put it on or put it on, measure interpersonal distances in everyday life and thus assess a risk of transmission. In addition, the clothing element can be designed to be inconspicuous, so that it is not noticeable in everyday life and is also not disturbing. The measurement of relevant distances to assess the risk of transmission is advantageous in everyday situations such as at the supermarket checkout and, in particular, also possible automatically. It is not necessary to install a special measuring device, which must also be installed on the user's body or over his clothing. In this way, compliance with interpersonal distances can be checked easily and effectively. It is also not necessary for other people to wear such a system.

A piece of clothing within the meaning of the invention can advantageously be worn on the user's body. In particular, the garment covers at least part of the body surface of the user. It may preferably have rigid and flexible sections. In principle, every possible clothing element can be used.

In particular, the measuring device comprises at least one output unit. An output signal can advantageously be output to the user and/or also to other persons by the output unit. Advantageously, this allows feedback on a current distance to a neighboring person at z. B. falling below a control distance. Advantageously, the output unit can be manually activated and deactivated again by the user using a switch.

The output unit preferably comprises at least one display unit and particularly preferably at least one optical display unit. In particular, the display unit includes, for example, light-emitting diodes or a display, such as an LCD display. It is advantageous if the output signal directly represents the result of a comparison between the evaluated distance and a predetermined control distance. In this case z. B. a clear feedback by a color code (red, green and e.g. also yellow) is possible, in which, for example, a color output of a light-emitting diode between green (sufficient distance) and red (insufficient distance) and possibly yellow (e.g. slightly below the minimum distance) changes. Advantageously, the user can easily be informed about the current distance from other people. The range of the control distance can be taken into account. Other people in the vicinity who do not keep the necessary safety distance can also be informed easily and immediately. The color of an LED on the item of clothing can also be easily perceived by a person nearby. In addition, it is also possible to show the currently measured distances on a display or a screen of the measuring device.

In at least one advantageous development, the output unit includes at least one haptic feedback unit such as a vibration unit. In particular, the vibration unit comprises at least one vibration motor. The vibration motor can advantageously be controlled by a processor unit. Vibrations can advantageously be generated by the vibration motor, which can be perceived primarily by the user of the item of clothing. In this way, a tactile feedback can be given to the user. Advantageously, perception of an output signal can thus be limited to the user.

In particular, the output unit can include at least one acoustic unit. The acoustic unit can be designed, for example, as a loudspeaker or as another acoustic element. An acoustic feedback is advantageously possible through the acoustic unit, such as a warning signal that is output, for example, when a predefined and/or adjustable control distance is not reached.

A combined function of different output units is possible.

The clothing element preferably comprises at least one outer clothing element. An outer clothing element can be worn in particular on the user's upper body, ie advantageously above the user's belt line. Such an outer clothing element can be designed, for example, as a pullover, T-shirt, headband, jacket, top, waistcoat, blouse or the like, or can include such an outer clothing item. Relevant distances during transmission can be advantageous for assessing the risk of transmission Pathogens are measured particularly advantageously from the upper body of the user and in particular from the outer clothing element. In particular, there is a small distance between the measuring device and the mouth, nose or ears of the user, through which pathogens can enter the human body particularly quickly.

In addition, it can nevertheless be possible for the clothing element or a part thereof to at least partially comprise an underclothing element such as trousers and/or also shoes.

The outer clothing element is particularly preferably designed as a mouth and nose mask. In particular, the mouth and nose mask comprises a mouth part and holding parts. The measuring device can advantageously be accommodated on a mouth part of the mouth and nose mask or even integrated therein. Advantageously, the measuring device can thus particularly precisely record the relevant mouth or nose or also the ears of a user to another person.

At least one recording unit is advantageously included. The measuring device can advantageously be removed and/or separably accommodated on the clothing element by the accommodation unit. A measuring device can advantageously be used in connection with different clothing elements. The clothing element can thus advantageously be cleaned and/or washed and/or replaced separately from the measuring device. In addition, the measuring device can be serviced without the clothing element.

The measuring device is preferably accommodated in a separate housing. The separate housing advantageously has an at least partially rigid outer shell. As a result, the measuring device is advantageously accommodated in a shock-proof manner. In addition, the housing of the measuring device can in particular also be waterproof or at least water-repellent, so that it is not damaged in the event of accidental contact with water or other liquids.

In particular, the receiving unit is designed as a pocket into which the measuring device can be inserted. The receiving unit advantageously comprises at least one bracket, through which the measuring device can be received on the item of clothing. The receiving unit can also be used particularly advantageously with disposable items such as medical masks.

In at least one advantageous development, the measuring device includes at least one sensor unit. In particular, the sensor unit enables the distance between the user and another person to be measured without contact. The sensor unit preferably comprises at least one ultrasonic sensor as the measuring sensor. In particular, the sensor unit comprises at least one infrared sensor. The sensor unit advantageously includes at least one radar sensor. For measuring the distance, the measuring sensors are advantageously constructed in a simple and robust manner. Such sensor types are cheap and can have a large measuring range of up to 20 meters and more. The measuring sensors enable non-contact measurement of the distance per runtime. In addition, a high local resolution of a measurement area is advantageously possible. In addition, the measurement signal can be evaluated directly so that the distance can be measured directly in everyday life, for example when walking or shopping. Several people and/or several distances can be detected simultaneously by the measuring sensors. Different measuring sensor types can be used together.

In at least one advantageous development, the sensor unit includes at least one camera unit as a measuring sensor. In particular, the camera unit can perform image recognition of the surroundings and filter them according to people. In particular, the camera unit can filter and/or distinguish the distances between persons and objects. In this way, it is possible to efficiently distinguish between relevant distances to people and irrelevant distances to objects such as houses. The image recognition and the evaluation can be carried out directly, so that an advantageous use in everyday activities is possible.

The camera can advantageously have a wide-angle function, so that a captured angle range is particularly large. In addition, it is also possible, for example, for an infrared temperature sensor to enable detection of living beings or differentiation between living beings and objects, based on the surface temperatures. Advantageously, several people can be detected at the same time.

In particular, the sensor unit has two or more measuring sensors of one sensor type. Advantageously, 2, 3, 5, 7 or even more measurement sensors can be included in the sensor unit. Advantageous a larger measuring range is made possible by the large number of measuring sensors. In particular, a larger angular range is possible due to a plurality of measuring sensors. Preferably, the measuring ranges of the individual measuring sensors can at least partially overlap, so that a spatial resolution within a measuring range is possible. Advantageously, not only distances can be measured, but also movements of people can be detected and predicted (interpolated). Advantageously, several people and their distances can be detected at the same time due to the overlapping measurement areas.

At least one measuring range of up to 5 m can preferably be detected by the sensor unit. At least one measuring range of up to 20 m can advantageously be detected by the sensor unit. In this way, advantageously, distances to people can already be detected whose distance is still so great that it is irrelevant to the user for the transmission of pathogens. Advantageously, the sensor unit has increased resolution close to the user while resolution is lower farther away. In all of the configurations of the invention, a negligible minimum measurable distance of a few centimeters in front of the user can be detected.

In at least one advantageous development of the invention, an angular range of at least 90° can be detected by the sensor unit. In particular, angular ranges of 150°, 180° or up to even 360° can be detected by the sensor unit(s). A large angular range for determining the distance is advantageously made possible in this way. In addition, it is possible that several sensors aligned in the same way are present in certain areas, such as a viewing direction of the user. A particularly high resolution is made possible in these areas, while, for example, a side or rear area is deliberately only partially monitored. In particular, a direction-dependent resolution is made possible in this way. A large angle range advantageously enables a high level of security. In particular, the angular range extends symmetrically in relation to a viewing direction of the user.

The measuring device advantageously comprises at least one processor unit. In particular, a measurement signal from the sensor unit can be evaluated by the processor unit. In particular, the processor unit comprises an Arduino NANO microprocessor. Such a microprocessor is inexpensive, freely programmable and has sufficient processing power for determining the distance.

It is also advantageously possible for the processor unit to have a data interface such as a W-Lan module, a radio module, a Bluetooth interface or an infrared interface. One data interface can preferably be loaded with data on the microprocessor, such as programs, or measurement sequences can be adapted. Current processor data, which in particular also contain the evaluated distances, can be read out and changed in a particularly simple manner. In particular, a smartphone with a special app or a computer can also be used for this purpose. It is also advantageously possible for the sensor unit and the processor unit to be coupled by radio, Bluetooth or an infrared data connection.

In at least one advantageous development, the processor unit can evaluate a distance between the user and another person with a frequency of at least 0.25 Hertz or 0.5 Hertz and in particular at least 1 Hertz. Advantageously, changes in distance can also be detected during faster or rapid movements, such as when walking (fast) or even when jogging (fast) or even when riding a bicycle in everyday life. In addition, sufficient security can also be granted by maintaining a minimum distance in situations, for example when the user moves or even walks through a supermarket or the like, where there can already be relatively small distances between people, which also change quickly be able.

Distances can also be evaluated particularly advantageously with a higher frequency of at least 2 Hz or 5 Hz or 10 Hz or even more. The accuracy of the measurement of the distance in everyday life is advantageously improved by the higher frequency.

The distance evaluated by the processor unit is advantageously comparable with at least one control distance that can be predetermined. An output signal can advantageously be output as a function of the comparison. The control distance can advantageously assume a value between 0.5 m or better 1 m and 5 m, for example. In particular, the control distance has a value of approx. 2.5 m and particularly preferably of approx. 1.5 m. In particular, it is also possible for larger control distances of up to 10 m or even more to be selected. Several control intervals can be specified, which can serve, for example, as levels for assessing the risk of transmission.

When the control distance is not reached, an output signal and in particular at least one warning signal is advantageously output. This output signal can signal to the user and/or the other person that the control distance has been undershot and therefore the risk of transmission of viruses or other pathogens is (significantly) increased. In particular, the control distance can be specified by the user. It is also possible for the control distance to be permanently specified within the processor unit. In any case, the control distance is smaller than the measuring range of the sensor unit, which determines the maximum measurable distance.

In at least one advantageous development, the processor unit includes at least one energy storage unit for supplying energy to the measuring device. In particular, the energy storage unit is designed as a battery unit and/or as an accumulator unit. The energy storage unit can be connected to the processor unit via a connection cable. The connection cable can be short or longer. The energy storage unit can, for example, also be accommodated in a pocket of another item of clothing or another pocket of the user.

The energy storage unit can also be accommodated on the processor unit. In particular, the energy storage unit can be integrated into the processor unit. In particular, the energy storage unit supplies the measuring device and the processor unit with electrical energy. In particular, the energy storage unit can be exchanged or exchanged. This provides a simple, convenient and cost-effective way of supplying energy.

The processor unit advantageously includes at least one memory unit. In particular, at least one memory unit is assigned to the processor unit. Programs or settings can advantageously be stored on the memory unit. In addition, it is also possible to save recorded distances and evaluate them with a time delay, for example after a walk or a visit to the supermarket. This enables a risk assessment for a longer period of time. In particular, the memory unit can be formed by an SD memory card or the like or can include one.

In preferred developments, the output signal of a processor unit can be output to the user and/or to other persons by an output unit. In this way, feedback can advantageously be given on the current distance or on falling below a control distance. The or an output signal can also (additionally) be output via radio. Also to people in the vicinity, in this respect (additionally) similar to the way the federal government’s Corona War app works, for example.

The applicant reserves the right to claim a method in which a measuring device is used to determine a distance between a user and at least one other person who is recorded on a garment of the user. Advantageous developments of the method emerge from the entire description and the claims.

Further advantages and features of the present invention result from the exemplary embodiments, which are explained below with reference to the enclosed figures.

In 1 a purely schematic view of an exemplary embodiment of a garment 1 according to the invention is shown. The item of clothing 1 here comprises a clothing element 2 which is designed as an outer clothing element 7 .

The outer clothing element 7 is designed here as a mouth and nose mask 8 . The mouth and nose mask 8 has a mouth part 8a and two holding parts 8b. The holding parts 8b can be placed around the user's ears, so that the mouth part 8a is held in front of the user's mouth and in particular also in front of his/her nose.

A receiving unit 9 is formed on the mouth and nose mask 8, on which the measuring device 3 is received. The receiving unit 9 is designed here as a pocket. The measuring device 3 is accommodated in a separate housing which is pushed into the accommodation unit 9 designed as a pocket. The measuring device 3 can thus be removed, for example to clean the mouth and nose mask. In addition, the measuring device 3 can be easily maintained and z. B. be cleaned if necessary.

The measuring device 3 has a sensor unit 10 with two measuring sensors 11, which are designed here as ultrasonic sensors, infrared sensors or as radar sensors. When used as intended, the measuring sensors are arranged directly in front of the user's mouth. In this way, a relevant distance for assessing the transmission risk between the user's mouth and at least one other person can be determined very precisely.

The sensor unit 10 is connected to the processor unit 13 . The processor unit includes an energy storage unit 22, which is designed here as a replaceable and rechargeable battery. The entire measuring device 3 is supplied with electrical energy by the energy storage unit 22 . In addition, a storage unit 22 is also provided or included, in which measurement data can be stored for later evaluation. The processor unit 13 receives the measurement signals from the measurement sensors 11 and uses them to determine the distance 4 . In addition, the distance 4 is compared with a predetermined control distance 18 within the processor unit 13 . Depending on the evaluated distance 4 and the comparison, the processor unit 13 outputs an output signal to the output unit 14 .

The output unit 14 here comprises two display units 19, a haptic feedback unit 20 and an acoustic unit 21. A display unit 19 is designed here as a display 19b. The currently measured distance is shown to a user 5 or another person 6 on the display 19b. Here the display 19b shows a value of “3m” as an example.

In addition, there is a second display unit 19, which here comprises two light-emitting diodes 19a, one light-emitting diode 19b lighting up “red” if the measured distance 4 is less than the control distance 18. The other light-emitting diode 19a lights up "green" if the measured distance 4 is greater than the control distance 18 (cf. 5a and 5b ). At least these light-emitting diodes 19a are particularly preferably included. A display 19b with the currently measured distance can optionally be omitted.

The haptic feedback unit 20 here comprises an (optional) vibration motor, i. H. a small electric motor with an imbalance. When the haptic feedback unit is activated, the user of the item of clothing 1 receives a tangible haptic feedback. A haptic feedback is output here if the measured distance 4 is smaller than the control distance 18. A haptic feedback unit has a considerable advantage over a (purely) acoustic feedback unit for deaf people, for example.

The acoustic unit 21 here also includes a (likewise optional) loudspeaker. The acoustic unit 21 emits an easily audible warning tone if the measured distance 4 is less than the control distance 18. It is also possible for an audible signal to be emitted whenever a new person is detected in the measurement area 15 of the sensor unit 10 , i.e. H. when the number of people 6 detected changes.

The angular ranges 16 of the measuring sensors 11 overlap here, so that both sensors can measure the distance 4 from a person. On the one hand, this can improve the accuracy with which the distance 4 can be determined. In addition, the measurement area 15 can also be spatially resolved. For example, it is possible to determine a local position within the measurement area 15 . In addition, possible movements can also be interpolated and predicted, so that statements about a (future) drop below the control distance 18 are also possible. In this case, even before the control distance 18 is undercut, an output signal can be sent as a warning to the user zero 5 are output. In addition, it would also be conceivable to use the user's own movement speed for the interpolation.

2 shows a purely schematic view of a further alternative exemplary embodiment of an item of clothing 1 according to the invention. Here, too, the item of clothing 1 according to the invention comprises a clothing element 2 which is designed as an outer clothing element 7 and further as a mouth and nose mask 8 .

The mouth and nose mask 8 is designed here as a disposable mask for one-time use. The recording unit 14 is designed here on the measuring device 3 as a bracket. The measuring device 3 can be pushed onto the disposable item from above or clipped onto it through the clip. The processor unit 13 and a haptic feedback unit 20 are arranged on the side facing the body. The sensor unit 10 with three measuring sensors 11 is arranged on the side facing away from the body and visible to other people. The measuring sensors 11 are designed here as infrared sensors. Furthermore, two display units 19 in the form of a display 19b and two light-emitting diodes 19a are included here.

After use, the measuring device 3 can be removed or separated from the mouth and nose mask 8 with a simple movement of the hand and attached to a new mouth and nose mask 8 .

3 shows a further exemplary embodiment of a garment 1 according to the invention. The clothing element 2 is designed here as an outer clothing element 7 and more precisely as a pullover 7a. The measuring device 3 is pushed into a pocket arranged on the chest area. The bag has a cutout so that the measurement sensor 11 of the sensor unit 10, which is designed as a camera unit, can capture the surroundings. An image recognition of the surroundings of the user 5 can be carried out by the camera unit. The images recorded by the camera unit can advantageously be filtered for people 6 so that people and objects can be distinguished.

4a and 4b show a further exemplary embodiment of a garment 1 according to the invention. The clothing element 2 is designed here as an outer clothing element 7 and more precisely as a headband 7b. A total of four measuring sensors 11 of a sensor unit 10 are present over the circumference of the forehead band 7, see the plan view in FIG 4b .

The measuring sensors 11 point in different directions, so that essentially the entire area around the user 5 can be detected by the measuring device 3 . In this case, the measuring sensors 11 do not have to be distributed evenly over the circumference. A viewing direction 17 of the user is detected here by a total of three measuring sensors 11, while only one measuring sensor 11 is arranged opposite to the viewing direction. As a result, the detection of distances 4 in the user's line of sight 17 becomes significantly more accurate.

The angular ranges 16 of the sensor units each have a value of approximately 150° here. As a result, the angular ranges 16 overlap, so that not only distances 4 but also movements and their direction relative to the clothing element 2 can be detected. In addition, feedback is provided here exclusively via a haptic feedback unit 17. A vibration can be felt on the head of the user 5 when a distance 4 from a person falls below the control distance 18.

5a and 5b show purely schematic views which illustrate the function of the item of clothing 1 according to the invention. The user 5 and the person 6 are shown in plan view from above. The item of clothing 1 has a sensor unit 10 with two measurement sensors 11 which are both aligned in the viewing direction 17 of the user 5 . In addition, further measuring sensors 11 are indicated (dashed).

The measurement sensors 11 of the sensor unit 10 here detect an angular range 16 of approximately 150°. The measuring area 15 has a radius of about 5 m. The control distance 18 is 2.5 m. The processor unit 13 records the measurement signals from the sensor unit 10 and evaluates them. The output signal is adjusted as a function of the evaluated distance 4 of the person 6 and its comparison to the control distance 18 . User 5 and/or person 6 receive feedback in the form of a warning if distance 4 is less than control distance 18, as in 5b shown.
