Abstract
Description
Technical Field
[0001] This invention relates to a sensor device and a device. Similarly, this invention relates to a method for informing users of the sensor device about the risk of viral infection in their surrounding environment. Background Technology
[0002] It is widely known that viral infections have a significant impact on public health and the socialized lifestyles of all social groups. Summary of the Invention
[0003] The present invention provides a sensor device having the features of claim 1, an apparatus having the features of claim 8, and a method having the features of claim 10 for informing a user of the sensor device of the risk of viral infection in their surrounding environment.
[0004] Advantages of the invention This invention proposes an effective method for determining localized viral infection risks using appropriate sensor devices, and for informing users of these risks. This invention is particularly advantageous in enclosed spaces, such as conference rooms and / or classrooms, where the localized viral infection risk is relatively high for the people gathered there. By enabling early identification of localized viral infection risks within a group of people using this invention, timely measures can be taken to prevent potential viral infections. In particular, the chain of infection can be broken through adaptive behaviors within the group, which can help contain viral diseases.
[0005] As will become clear from the following description, by utilizing (only) standard and low-cost sensor types, the present invention enables reliable determination of the local risk of viral infection for the user of the invention. In particular, prior art devices equipped with at least gas sensor facilities and air humidity sensor facilities can be further extended by means of easily implemented programming steps to enable said devices to implement the present invention. Therefore, the use of the present invention can be achieved in a low-cost manner.
[0006] In an advantageous embodiment, the sensor device additionally includes a particle sensor facility by means of which can output particle information for at least one predetermined particle size range regarding the possible presence of such large particles in the surrounding environment at at least one separately predetermined minimum concentration and / or minimum amount and / or regarding the concentration and / or amount of said particles in the surrounding environment. This particle information can be provided to analytical evaluation electronics by means of a control facility such that at least infection risk information can be determined by the analytical evaluation electronics in addition to taking the particle information into account. The particle information is information about the effectiveness of the current air quality in the environment surrounding the sensor device. Therefore, the particle information is also suitable for reliably determining the risk of viral infection in the surrounding environment.
[0007] Alternatively or additionally, the sensor device may also include at least one microphone facility, by means of which can output volume information regarding the possible presence of sound waves contained in at least one predetermined sound frequency range in the surrounding environment at at least one separately predetermined minimum volume and / or regarding the volume of the sound waves in the surrounding environment, wherein the volume information may be provided to the analysis and evaluation electronics by means of a control facility such that at least infection risk information can be determined by means of the analysis and evaluation electronics in addition to taking the volume information into account. For example, the volume information can reliably reflect how many people are currently present in the surrounding environment of the sensor device, and correspondingly how high the risk of viral infection is in the surrounding environment.
[0008] Similarly, the sensor device may additionally include a temperature measuring facility that can output temperature information about the temperature present in the surrounding environment. This temperature information can be provided to the analysis and evaluation electronics via a control facility so that at least infection risk information can be determined by the analysis and evaluation electronics in addition to taking the temperature information into account. The temperature in the surrounding environment typically also affects the risk of contracting viral diseases in that environment. Therefore, it is advantageous in this embodiment to consider temperature information when determining infection risk information.
[0009] Preferably, the sensor device additionally includes a barometric pressure measurement facility that can output barometric pressure information about the air pressure present in the surrounding environment. This barometric pressure information can be provided to the analysis and evaluation electronics via a control facility so that at least infection risk information can be determined by the analysis and evaluation electronics in addition to taking the barometric pressure information into account. Thus, another low-cost sensor type can be used to reliably determine infection risk information.
[0010] For example, the analysis and evaluation electronics can be integrated within the sensor device's housing or within the housing of the device equipped with the sensor device. This analysis and evaluation electronics can determine infection risk information, at least considering confirmatory and / or measurement information and air humidity information. Alternatively, however, by outputting at least the confirmatory and / or measurement information and air humidity information to an external / "central" analysis and evaluation electronics device via a control facility, it is possible to forgo equipping the sensor device with its own analysis and evaluation electronics. Reliable operation of the sensor device is guaranteed in both cases.
[0011] As an advantageous further extension, at least one warning, at least one action suggestion, and / or at least one inaction suggestion can be identified as at least one prompt derived from infection risk information by means of an analytical evaluation electronic device. In the case of using lighting facilities, image display facilities, and / or sound output facilities, notifying the user of at least one warning, at least one action suggestion, and / or at least one inaction suggestion via at least a sensor device can at least alter the user's behavior in such a way that at least the user is better protected from viral infection, and thus the chain of infection is limited or interrupted.
[0012] Devices with this type of sensor also achieve the aforementioned advantages. These devices can be, for example, mobile devices, mobile phones, and / or iPhones.
[0013] Furthermore, implementing a corresponding method for informing users of the sensor device about the risk of viral infection in their surrounding environment also provides the aforementioned advantages. It should be explicitly noted that this method can be further extended according to the above-described implementation of the sensor device. Attached Figure Description
[0014] Other features and advantages of the invention are explained below with reference to the accompanying drawings. The drawings show: Figure 1a and 1b : A flowchart and coordinate system for explaining one implementation of a method for informing users of a sensor device about the risk of viral infection in their surrounding environment; Figure 2 A schematic diagram of the first embodiment of the sensor device; and Figure 3 : A schematic diagram of a second embodiment of the sensor device. Detailed Implementation
[0015] Figure 1a and 1bA flowchart and coordinate system are shown for explaining one implementation of a method for informing users of sensor devices about the risk of viral infection in their surrounding environment.
[0016] As will become clear from the following description, the methods described below can be implemented using a wide variety of different sensor device types, which are at least equipped with gas sensor facilities and air humidity sensor facilities. Therefore, the sensor devices used to implement the methods can also be used for a variety of other purposes. Thus, the usability of the sensor devices is not limited to determining the risk of viral infection in the user's surrounding environment and informing the user accordingly.
[0017] The user of the sensor device should be understood as a person existing in the surrounding environment of the sensor device. Therefore, the surrounding environment is the environment surrounding both the sensor device and its user. For example, the surrounding environment can be understood as a space in which the sensor device and the user exist.
[0018] The method described herein has method step S1, which may also be described as a measurement and / or verification step. Method step S1 includes at least sub-steps S1a and S1b, but may also include other sub-steps, such as (optional) sub-steps S1c to S1f.
[0019] In sub-step S1a, confirmatory and / or measurement information is determined for at least one pre-given gas and / or at least one pre-given gas group / gas category. The confirmatory and / or measurement information for the at least one pre-given gas and / or the at least one pre-given gas group reflects the possible presence of the gas / gas group in the ambient environment at at least one respectively pre-given minimum concentration and / or minimum amount and / or reflects the concentration and / or amount of the gas / gas group in the ambient environment. Preferably, in sub-step S1a, (at least) for groups of volatile organic compounds (VOCs), the possible presence of the volatile organic compounds in the ambient environment at at least one respectively pre-given minimum concentration and / or minimum amount and / or the concentration and / or amount of the volatile organic compounds in the ambient environment are determined. The presence of a specific gas, for example, especially gases from a group of volatile organic compounds, provides valuable information about the air quality in the ambient environment.
[0020] To implement sub-step S1a, a gas sensor facility of a sensor device is used. It should be clearly stated here that the feasibility of sub-step S1a is not limited to a specific sensor type of the gas sensor facility. Rather, multiple different types of gas sensors can be used (together) to implement sub-step S1a.
[0021] In sub-step S1b, air humidity information regarding the air humidity in the surrounding environment is determined. Sub-step S1b is implemented using an air humidity sensor facility of a sensor device. The air humidity in the surrounding environment typically has a significant impact on the spread of viral infections among people present there.
[0022] In (optional) sub-step S1c, particle information can be determined for at least one pre-given particle size range, expressing that particles of such size may be present in the surrounding environment at at least one respectively pre-given minimum concentration and / or minimum amount and / or expressing the concentration and / or amount of said particles in the surrounding environment. The particle information also enables the inference of air quality in the surrounding environment. To measure the particle information, a particle sensor facility of a sensor device can be used.
[0023] If the sensor device additionally includes a microphone, volume information can also be determined for at least one pre-defined sound frequency range in (optional) sub-step S1d. The volume information for the at least one pre-defined sound frequency range reflects the presence of sound waves contained within that range in the surrounding environment at at least one pre-defined minimum volume / intensity and / or reflects the volume / intensity of the sound waves in the surrounding environment. The presence of a person can be determined from the volume information, for example, but the presence of an animal can also be determined.
[0024] Optionally, temperature information regarding the temperature present in the surrounding environment can also be determined in sub-step S1e using the temperature measurement facility of the sensor device. Optionally, as an optional sub-step S1f, pressure information regarding the air pressure present in the surrounding environment can also be determined using the air pressure measurement facility of the sensor device. The temperature and / or air pressure in the surrounding environment can have a significant impact on the spread of viral infection among people present there.
[0025] In addition to the sub-steps S1a to S1f described herein, other measurements and / or surveys may be performed during method step S1. For example, motion sensors, light sensors / brightness sensors, motion alarms, sensors for determining radio frequency frequencies (for detecting nearby mobile devices), and / or at least one door and / or window opening sensor may be used to obtain other sensor data about the environment surrounding the sensor device during method step S1, for determining other sensor data. Similarly, in method step S1, location information of the surrounding environment, particularly information about the space in which the sensor device is located, may be determined by means of positioning facilities of the sensor device or devices cooperating with the sensor device.
[0026] As an advantageous further extension, the method described herein may also have an (optional) method step S2 in which additional data is queried. For example, in an (optional) sub-step S2a of method step S2, a user of the sensor device may be required to report specific data via manipulation of the input facilities of the sensor device or a device cooperating with the sensor device. This type of data may be, for example, location information of the surrounding environment, particularly information about the space where the sensor device is located, and / or specific data for that space, such as, in particular, its size, number of windows, (approximate) window dimensions, number of doors, (approximate) door dimensions, and / or the presence or absence of a ventilation system in the respective corresponding space.
[0027] Alternatively or supplementarily, in the (optional) sub-step S2b of method step S2, (other) data can also be queried from an information output point outside the sensor device, for example, via the Internet. An information output point can be understood, in particular, as an information output point located outside the surrounding environment of the sensor device. For example, external air temperature, external air pressure, wind speed, external air quality values, and / or local infection rates can be queried from the information output point as data. If the location information of the surrounding environment, particularly the space where the sensor device is located, is known through a positioning facility or through the user's manipulation of the input device, then specific data for that space can also be queried from the information output point in the (optional) sub-step S2b, such as, in particular, its space size, the number of its windows, the window sizes, the number of its doors, the door sizes, and / or whether a ventilation system exists or not in the respective corresponding space.
[0028] Following method step S1 and possibly method step S2, as method step S3, infection risk information regarding the risk of viral infection in the surrounding environment is determined. The determination of infection risk information is performed at least considering confirmed and / or measured information and air humidity information. Advantageously, particle information, volume information, temperature information, air pressure information, other sensor data obtained during method step S1, and / or data queried during method step S2 can also be considered when determining infection information. In particular, confirmed and / or measured information and air humidity information, along with other information listed herein, sensor data, and queried data, provide important indications about the current air quality in the environment surrounding the sensor device. Therefore, infection risk information can be determined promptly and reliably by using / utilizing computational tools based on simple interrelationships, at least one mathematical-physical model, and / or machine learning methods. In particular, dynamic pathogen concentrations in the surrounding environment can be simulated for this purpose, and the dynamic and accurate infection risk of the surrounding environment can be calculated / derived in this way. This can also be described as a real-time, individualized calculation of the risk of viral infection in the environment surrounding the sensor device. Therefore, it is possible to reliably quantify the risk of infection with viral diseases, such as, in particular, Covid-19.
[0029] The determination of infection risk information, implemented as step S3, is performed using an analysis and evaluation electronic device. As will become clear from the following description, the analysis and evaluation electronic device may be / include a unit comprising at least one sensor device itself and / or at least one unit external to the sensor device. In both cases, the information / sensor data obtained in step S1 and / or the data queried in step S2 can be stored / recorded at periodic intervals. Therefore, to determine the real-time (local) risk of viral infection, dynamic modeling can be implemented, the parameters of which are based on real-time data and simultaneously utilize previous values, meaning that changes in data that have occurred in the environment surrounding the sensor device are taken into account. Continuous improvement based on machine learning, through "self-learning" of individualized conditions, is also possible.
[0030] By continuously implementing method step S3 (with corresponding repetition of at least method step S1 and possibly method step S2), it is possible to continuously reassess the risk of viral infection throughout the entire duration of residence in the environment surrounding the sensor device. In this way, increased risk can be reliably identified, particularly in enclosed spaces. Enclosed spaces can be, in particular, offices, kindergartens, classrooms, gymnasiums, fitness centers, hotel rooms, or restaurants in the catering industry. Mathematical models for calculating infection risk indices in each of these spaces can be readily established. In the corresponding calculations, other parameters can also be dynamically responded to, such as space occupancy, the presence of people and / or animals, respiratory rate, pathogen concentration in exhaled air, mask filtration efficiency, space volume, survival time of detected / hypothesized viruses, ventilation inflow rate, ventilation outflow rate, pathogen input concentration, filtration rate, and / or filtration efficiency.
[0031] With the help of Figure 1b The coordinate system shown is an example of a method step S3, with the horizontal axis being the time axis t. Figure 1b A curve in the coordinate system reflects the VOC concentration c measured in sub-step S1a. VOC . Figure 1b Another curve in the coordinate system shows that, at least when considering VOC concentration c VOC The risk value R, determined as at least part of the infection risk information, is based on (not shown) air humidity. As shown in curve c... VOC As can be seen from R, especially when the VOC concentration c VOC When the risk of viral infection in the surrounding environment decreases and / or becomes relatively low, it can be considered that the risk is relatively high.
[0032] As a possible further extension of the method described herein, an optional method step S4 may be implemented after method step S3, in which at least one prompt is derived from the identified infection risk information using an analysis and evaluation electronic device. This prompt would be useful to the user of the sensor device due to a potentially relatively high risk of viral infection in the user's surrounding environment. For example, at least one warning, at least one action suggestion, and / or at least one inaction suggestion may be determined as at least one prompt derived from the infection risk information using the analysis and evaluation electronic device. In particular, an infection warning, a ventilation suggestion, a request to leave the current surrounding environment, a request to wear a mask, and / or a suggestion not to touch one's face with one's own hands may be determined as at least one prompt in method step S4.
[0033] In method step S5, which may be implemented after method step S3 and possibly after method step S4, considering the determined infection risk information and / or at least one prompt derived from the infection risk information, lighting facilities are manipulated to display corresponding light signals, image display facilities are manipulated to display corresponding image signals, and / or sound output facilities are manipulated to emit corresponding sound signals. The lighting facilities, image display facilities, and / or sound output facilities can be understood as facilities of the sensor device and / or devices cooperating with the sensor device, respectively. All of this enables personalized and rapid notification / alerts to the user of the sensor device. For example, the user of the sensor device can be shown a hue corresponding to the determined risk value R by means of lighting facilities in this way. As a further extension, at least one fixed device in the surrounding environment, such as an automatic ventilation device, an automatic window opening device, and / or an automatic door opening device, can also be manipulated based on the determined infection risk information, particularly to induce (better) ventilation of the surrounding environment.
