Description

Technical field

The present invention relates to a distance detection device for maintaining distances and recording resulting person-to-person contacts. In the following, person-close contacts are those contacts between at least two people, for which the people do not keep a defined minimum distance, whereby the minimum distance is usually between 1 and 2 meters, but depending on the initial situation and the risk situation by the relevant institution can be defined larger.

The device according to the invention is used primarily in areas where infection chains (e.g. flu, Covid19, Sars, etc.) are to be interrupted. This applies to the entire public space - institutions, such as universities, hospitals, offices or libraries, in offices, shops, transport, as well as in parks or playgrounds. In short, wherever close contact is likely (but undesirable) - public, private, business.

State of the art

Solution approaches are already known from the prior art which, in current and past cases, are purely software-based and are based on evaluations of mobile phone data (acquired via mobile radio operator) or on the voluntary use of applications by the population - for example the “Stop Corona” -App from the Austrian Red Cross or "MyHealth" app from the WHO.

Other measures to prevent infections include protective masks, gloves and hands, various forms of disinfection or sterilization and so on. However, the decisive factor is always the direct close contact of people or their avoidance (droplet infection). Most people / cultures cannot understand the importance of such a behavioral measure and therefore do not adhere to it sufficiently. This is one of the biggest problems facing governments and institutions in times of crisis.

There are also no existing solutions in terms of hardware and distance measurement. Smartphones, Bluetooth, GPS or RSSI measurements are too imprecise for this purpose. There are also no products on the market that offer such distance measurements.

Disadvantages of the previously known solutions

The biggest problem is that the existing solutions mostly either violate the basic data protection rights of most western countries (e.g. mobile phone surveillance, such as is used in South Korea) or do not add any decisive added value (e.g. the "Stop Corona" - App of the Austrian Red Cross) because they only rely on existing devices (smartphones), require enormous initiative and consent, also process personal data and the coverage or effect to be achieved in this way is almost negligible.

Otherwise, floor markings and information boards, plexiglass “spit protection walls” on counters and counters, protective masks (covering mouth and nose), instructions for proper hand washing and so on are also used. But the sum of such measures is also not sufficient in an emergency.

It is crucial that people keep a minimum distance from each other. “Social Distancing” works poorly on its own.

Hardware: For the purpose of distance measurement (between two or more devices, in the measuring range of 1-3 m and an accuracy of less than 0.2 m), smartphones, Bluetooth or RSSI measurements are too imprecise and GPS is only functional outdoors.

Presentation of the invention

The present invention has for its object to provide a distance detection device for maintaining distances and recording of person-to-person contacts, which eliminates the aforementioned disadvantages and by means of which non-avoided person-to-person contacts can be recorded without using personal data .

According to the invention the above object is achieved in accordance with the preamble of claim 1 in conjunction with the characterizing features. Advantageous refinements and developments of the distance detection device according to the invention are specified in the dependent subclaims.

According to the invention, a distance detection device of the type mentioned at the outset is characterized in that it has a transmitter and a receiver for distance detection to at least one further distance detection device with a transmitter corresponding to the transmitter and receiver and one Receiver comprises, wherein the distance detection device checks the surroundings of the distance detection device within a defined radius for the presence of one or more further distance detection devices, the distance detection device being assigned at least one device-specific identification feature which does not contain any personal data of a person, if a defined value is undershot If one or more further distance detection devices are removed from the distance detection device, the identification feature of the further distance detection device (s) detected by the distance detection device is stored and / or sent to a receiving device, which in turn stores and / or evaluates the detected identification features.

Compared to existing solutions, the facility at hand offers the combination of practical use and data security or anonymity. As no personal data is collected or used, no declarations of consent or data protection violations are required to collect the necessary information. With this decisive advantage, the distance detection device is easy to use in large numbers and can, with appropriate coverage, contain crucial infection chains. This in turn enables the economy and public space to be largely maintained without endangering people through infection and at the same time keeping the disease curves flat. In short, the facility enables governments to avoid having to choose between protecting people and maintaining the economy. At the same time, people are offered individual and immediate protection and security. By identifying herds of infection, spreading data and origins in this way, more targeted and therefore more effective further measures can be taken.

• 1 a schematic representation of a first and a further distance detection device, each of which a mobile device (smartphone, tablet, etc.) and a central database (cloud) is assigned.

Implementation of the invention

How out 1 can be seen, the detected identification features and any additional information by the distance detection devices 1' to a receiving device 2nd in the form of a mobile device 2nd or computer.

It is particularly advantageous that at least one additional item of information relating to the one or more additional distance detection devices at the time of detection 1" present status of the distance detection device 1' and / or the distance detection device 1" recorded and stored and / or to the receiving device 2nd is sent and stored and / or evaluated there, but the additional information does not contain any personal data relating to the user.

An application is advantageously on the mobile device or on the computer A provided, by means of which a health status of the user can be set and / or stored, the features stored on the mobile device or the computer, any information relating to the distance detection device (s) 1 ', 1 "and the health status in at least one central database D are stored and evaluated, it being particularly advantageous if the in the at least one central database D stored and / or evaluated information in relation to any person-close contacts and the health status of the users of distance detection devices who are in person-close contact with one or more users 1" are publicly available without the personal data of the respective user or identification features of distance detection devices 1' , 1" be publicly displayed, in order to achieve in this way preferably that the linking of identification features and any additional information only about the "possession" of the respective distance detection devices 1' , 1" can be done.

The central upload of the person-to-person contacts (in the form of completely anonymous data) into a publicly accessible database (e.g. a cloud) makes it possible to determine whether potential infections could have occurred. This enables authorities to react in a targeted manner and to inform affected facility owners without knowing their contact details. In turn, the facility owners themselves can practice active self-protection and are trained in mindfulness. Risk groups (e.g. old or pre-ill people or people in exposed occupational groups) can also be protected in a more targeted manner. In addition, the area-wide use of the distance detection device according to the invention 1' In times of crisis, governments keep the economic situation largely at the usual level instead of alternatively closing large parts of the trade and the leisure industry to protect the population.

The status for one's own distance detection device can advantageously be obtained via the application 1' be set ("Healthy", "Suspected Infection", "Infected", "Recover and Immune", ...). Under certain circumstances, this can also be suggested or even carried out by a doctor or an authority.

Further information can be provided by the device owner on a voluntary basis, such as a location (district, district, zip code, etc.). These are only in the personal application A stored, not on the distance detection device 1' and can be revoked at any time. Where people-close contact cannot be prevented (flatmates, close families, etc.), distance detection devices can be used 1' , 1" define a special status for each other, which deactivates warning tones and vibrations.

The application A also stores the data in a central and publicly accessible database in the cloud. It can indicate to the user at any time whether he / she was in contact with another person and whether they were or are infected or whether they were in contact with the infected (within a defined period of time) - i.e. whether there was any contagion potential.

In a very particularly advantageous embodiment of the invention, the duration of falling short of the defined distance E determined, the storage and / or transmission of the detected identification features and any additional information to a receiving device 2nd only after exceeding a defined duration of falling short of the distance E he follows.

In a further advantageous embodiment of the invention, after a defined period of time the distance has been undershot E on the distance detection device 1' or on the mobile device 2nd an optical, acoustic and / or haptic signal is output.

The distance detection between the distance detection devices 1' , 1" According to the invention, this is preferably carried out by means of short-range radio communication, with ultra-broadband technology being very particularly preferably used.

The distance detection device 1' preferably comprises a short-range radio communication module, by means of which the distance detection between the distance detection device 1' and the further distance detection device / s 11 " takes place, the short-range radio communication module of the distance detection device 1' - As described above - preferably uses an ultra-broadband technology.

Furthermore, the distance detection device according to the invention includes 1' a Bluetooth module for communication and data transmission between the distance detection device 1' and a mobile device or computer.

The distance detection device 1' can not only act as a representative for people or animals (by wearing it on the body), it can also mark a sensitive point, such as a counter / counter. The distance detection device 1' can therefore also be used with a wide variety of "envelopes" - e.g. B. with bracelet, clamp, simple case, ... The distance detection devices 1' , 1" the collected data (ID, time) can be sent to a mobile application via Bluetooth A / Hand over computer.

A special form of application can still be used for institutions A are provided in which third-party devices can also be registered. However, only the ID of the distance detection device is read out 1' - The institution can then only update the status independently. Prioritization could also take place using the identification features. For example, tests could be carried out primarily on people who warn the application A have recently had contact with infected people. At no time will personal anonymity be violated or data will be passed on. It is also not possible to determine the identity of the wearer.

The distance detection device according to the invention 1' is not limited in its explanations to the preferred embodiments specified above. Rather, a large number of design variations are conceivable, which make use of the solution shown even when the design is fundamentally different.
