MONITORING SYSTEM, MASK SYSTEM, USE OF A MONITORING SYSTEM, METHOD FOR MONITORING, COMPUTER PROGRAM PRODUCT AND COMPUTER- READABLE MEDIUM

[0001] This application is a United States National Phase Application of International Application PCT / DE2024 / 100996, filed November 25, 2024, and claims the benefit of priority under 35 U.S.C. §119 of German Application 10 2023 135 380.2, filed December 15, 2023. TECHNICAL FIELD

[0002] The present invention relates to a monitoring system for monitoring the use of a face mask. Furthermore, the invention relates to a mask system comprising a face mask and a monitoring system. The invention also relates to the use of a monitoring system with a face mask, a method for monitoring the use of a face mask by means of a monitoring system, a computer program product and a computer-readable medium. BACKGROUND

[0003] A wide variety of face masks are known, most of which provide the user with a respiratory air flow. Depending on the use and area of application, the different mask systems comprise the provision of the respiratory air flow from a supply source and / or tank devices and / or the filtration of an air flow from the environment.

[0004] The currently publicly known mask systems in the prior art do not usually comprise sensors for monitoring the use of a face mask.

[0005] Known mask systems in medical technology mostly only have stationary sensors for detecting an input flow into a face mask. Known mask systems from the technical field of respirator masks, such as those used by firefighters, mine workers, industrial personnel and / or pilots, usually do not have any sensors for monitoring the fluid flows, since generally healthy people are supplied with clean gases for breathing. In the known prior art, there is no monitoring as to whether the face masks are used and / or applied correctly. SUMMARY

[0006] It is therefore an object of the present invention to eliminate or at least partially eliminate the disadvantages in the prior art described above. In particular, it is an object of the invention to provide a monitoring system with which the use of a face mask can be monitored in a particularly simple manner. In particular, it is also an object of the invention to provide a mask system comprising a face mask and a monitoring system, as well as the use of a monitoring system comprising a face mask, a method for monitoring the use of a face mask by means of a monitoring system, a computer program product and a computer-readable medium.

[0007] The aforementioned object is achieved by features presented with this disclosure.

[0008] In particular, the object is achieved by a monitoring system having a monitoring system comprising a detection device, which is configured to detect at least one signal of at least one gas flow of the face mask; and a control unit which is configured to process the at least one signal detected by the detection device, and wherein the control unit is configured to monitor a use of the face mask on the basis of the processing.

[0009] Furthermore, the object is achieved by a mask system having a face mask and the monitoring system, by a monitoring system method providing the monitoring system and connecting the monitoring system with the face mask for use of the monitoring system, by a method for monitoring the use of a face mask including detecting at least one signal of at least one gas flow of the face mask by means of the detection device of the monitoring system, processing the signal detected by the detection device by means of the control unit of the monitoring system, and monitoring the use of the face mask on the basis of the processing, and by a non-transitory computer program product and a computer-readable medium (non-transitory computer-readable medium) having the features as disclosed herein.

[0010] Further advantages and details of the invention can be found in the claims, the description and the drawings. Features described in connection with the monitoring system according to the invention of course also apply in connection with the mask system according to the invention, the use according to the invention, the method according to the invention, the computer program product according to the invention, the computer-readable medium according to the invention, and vice versa, and therefore the disclosures of the individual aspects of the invention always refer to one another or can refer to one another.

[0011] According to a first aspect of the invention, the object is achieved by a monitoring system for monitoring the use of a face mask. The monitoring system comprises a detection device and a control unit. The detection device is configured to detect at least one signal of at least one gas flow of the face mask. The control unit is configured to process the at least one signal detected by the detection device and to monitor the use of the face mask on the basis of the processing.

[0012] Monitoring the use of a face mask within the scope of the invention is preferably understood as monitoring the correct use and / or the application state of the face mask to a user. The essence of the invention is preferably to allow monitoring of the correct way of wearing the face mask. Monitoring of the use of the face mask is achieved by detecting and processing at least one signal of a gas flow of the face mask. The at least one gas flow, as described in detail in the following sections, is preferably to be understood as an incoming and / or outgoing gas flow into and / or out of the face mask and / or the monitoring system.

[0013] The detection device is configured to detect at least one signal of the at least one gas flow. For example, the detection device is configured as and / or comprises at least one flow sensor. The at least one signal is preferably to be understood as the detection of an air flow, a respiratory air flow and / or a respiratory gas flow. The detection of the at least one signal preferably comprises monitoring a volumetric flow rate of the at least one gas flow and / or monitoring the gas composition of the at least one gas flow. Preferably, the detection of the at least one signal comprises measuring at least one CO2 value and / or oxygen value of the at least one gas flow.

[0014] The control unit is preferably configured as a logic unit and for receiving and / or sending data, in particular from the detection device. The control unit allows the processing of the at least one detected signal in order to monitor the use of the face mask. The processing comprises, for example, an evaluation and / or a comparison of the at least one detected signal, in particular over time. The at least one detected signal is preferably compared with comparison data from the control unit and / or with previously detected signals. For example, the processing of the at least one signal is used as an evaluation to recognize inspiration phases and / or expiration phases of a user.

[0015] The processing preferably comprises storage and / or provision of the at least one detected signal and / or of the data processed therefrom by means of the control unit. The processing is preferably to be understood as an analysis and / or evaluation of the at least one detected signal. The control unit is preferably configured to output and / or provide the at least one processed signal and / or the data generated therefrom to at least one output device, storage device and / or server device.

[0016] The control unit and the detection device are preferably configured together in a main body and / or a housing. Alternatively, the detection device is separate from the control unit. The detection device is preferably connected to the control unit in a wired or wireless manner for data communication.

[0017] A monitoring system configured in this way is particularly advantageous because at least one signal of at least one gas flow of the face mask can thereby be detected in a particularly simple manner, as a result of which the use of a face mask can be monitored in a particularly simple manner.

[0018] According to a preferred development of the invention, it can be provided in a monitoring system that the control unit is configured for case differentiation of the use of the face mask on the basis of the processing, wherein the case differentiation of the use of the face mask comprises at least the following cases: - the face mask is correctly applied, and the user is breathing only an input gas flow of the face mask, - the face mask is not tightly applied, and the user is breathing the input gas flow and ambient air, - the face mask is not applied, and the user is breathing only ambient air.

[0019] The processing of the at least one detected signal by the control unit is particularly advantageous if the control unit allows case differentiation for monitoring the use of a face mask. For this purpose, the control unit preferably comprises a differentiation device, which is configured for case differentiation of the use of the face mask on the basis of the processing.

[0020] For example, the at least one detected signal and / or a signal curve of the detection device, in particular an inspiratory and / or expiratory flow rate sensor, is evaluated in order to differentiate between the cases. For example, in the first case mentioned, where the face mask is correctly applied, and the user is breathing only the input gas flow, a clear distinction between phases with and without through-flow and / or between inspiration phases and / or expiration phases can be detected by the detection device and processed by the control unit. In clear terms, the signal curves of different inspiration phases and / or expiration phases have slight fluctuations in their curve if the face mask is correctly applied and the user is breathing only the input gas flow. For example, with a processing period of two to five consecutive breathing cycles, the through-flow curves and / or signals are within a tolerance range of at most + / - 15%, in particular at most + / - 10%, relative to one another. For example, an inhalation volume and / or an exhalation volume can be determined by the control unit from the processing of the at least one detected signal. For example, in the first case mentioned, an integral calculation over the inspiration phases and / or expiration phases of a processing period is constant or substantially constant.

[0021] Within the scope of the invention, the phrase "X or substantially X" is to be understood as a possible, minor deviation, for example due to manufacturing tolerances, material and / or process properties, without altering the underlying, intended function of the feature.

[0022] The control unit is configured, for example, to determine a standard deviation and / or variance of the volumes on subsequent averaging of the volumes over multiple inhalation / exhalation cycles. For example, in the first case mentioned, the inhalation / exhalation cycles have a low standard deviation and / or variance of the volumes when the volumes are subsequently averaged over multiple inhalation / exhalation cycles.

[0023] For the second case mentioned, where the face mask is not tightly applied, and the user is breathing the input gas flow and ambient air, the control unit is preferably configured to recognize a corresponding change. For example, the phases with and without through-flow can be recognized in the signal curve by the control unit and can therefore only just be differentiated between inhalation and exhalation.

[0024] The control unit is preferably configured to recognize large differences in the signal curves of different inspiration phases and / or expiration phases in the second case mentioned. For example, with a processing period of two to five consecutive breathing cycles, the through-flow curves and / or signals are within a tolerance range of over + / - 40%, in particular over + / - 30%, relative to one another. For example, in the second case mentioned, an integral calculation over the inspiration phases and / or expiration phases of a processing period is inconsistent or substantially inconsistent. For example, in the first case mentioned, the inhalation / exhalation cycles have a high standard deviation and / or variance of the volumes when the volumes are subsequently averaged over multiple inhalation / exhalation cycles.

[0025] The second case mentioned is preferably to be understood as an incorrectly applied face mask or a face mask that is applied to the face such that it does not provide a continuous seal.

[0026] In the third case, where the face mask is not applied, and the user is only breathing ambient air, the control unit is preferably configured to recognize an absence of phases with and without through-flow in the signal curve. In clear terms, there is no flow through and / or around the detection device according to the invention in the third case. The third case mentioned is preferably to be understood as a face mask that is not applied.

[0027] Within the scope of the invention, it is preferable that the three cases mentioned only represent reference points for a smooth transition between the possible use cases of the face mask.

[0028] The control unit is preferably configured to differentiate between a plurality of cases, which are characterized by way of example in the three cases mentioned. For example, the control unit is configured to process the at least one signal detected by the detection device in such a way that the control unit provides a percentage probability of using the face mask according to at least one of the cases mentioned.

[0029] A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the case differentiation by the control unit.

[0030] According to a preferred development of the invention, it can be provided in a monitoring system that the detection device comprises an input detection device and / or an output detection device, wherein the input detection device is configured to detect a signal of an input gas flow into the face mask, and / or wherein the output detection device is configured to detect a signal of an output gas flow out of the face mask.

[0031] The detection device is therefore configured to detect at least one incoming and / or at least one outgoing gas flow into and / or out of the face mask. The control unit according to the invention is preferably configured to process the signal detected by the input detection device and / or by the output detection device. The above-described processing of the at least one detected signal, in particular for the above-described case differentiation, is therefore preferably carried out with the at least one signal detected by the input detection device and / or by the output detection device.

[0032] The input detection device and the output detection device are preferably configured in a common main body and / or housing. The input detection device and the output detection device are preferably analogous or even identical.

[0033] The input detection device and / or the output detection device are preferably connected to the control unit for data communication.

[0034] Additionally or alternatively, the configuration of the detection device as an input detection device and an output detection device allows the detected signals of the input gas flow and the output gas flow to be compared with one another by the control unit.

[0035] For example, a monitoring system configured in this way makes it possible to check the plausibility of the case differentiation and / or the situation recognitions by the input detection device and the output detection device.

[0036] For example, an inspiratory and an expiratory flow rate sensor is evaluated by the control unit, so that a balancing between inhalation volumes and exhalation volumes or multiple inhalation volumes and exhalation volumes is possible. In clear terms, the user is partially breathing ambient air if the deviations between the inhalation volumes and exhalation volumes are <semantics>>10%<annotation encoding="application / x-tex">> 10\%< / annotation>< / semantics>.

[0037] A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner thanks to the configuration of the detection device as an input detection device and / or an output detection device.

[0038] According to a preferred development of the invention, it can be provided in a monitoring system that the monitoring system, in particular the detection device, comprises a pressure detection device for detecting a pressure within the face mask, wherein the control unit is configured to process the pressure detected by the pressure detection device. Monitoring of the use of a face mask is also preferably made possible by the pressure detection device.

[0039] The pressure detection device is configured to detect a pressure within the face mask and therefore advantageously allows monitoring of whether the face mask is correctly applied for and / or to a user. At least some portions of the pressure detection device can preferably be arranged within the face mask and / or a supply tube of the face mask. The pressure detection device is preferably configured together with the input detection device and / or the output detection device in a main body and / or housing.

[0040] The pressure detection device is preferably connected to the control unit for data communication. The control unit is preferably configured to process the at least one pressure detected by the pressure detection device, wherein the control unit is configured to monitor the use of the face mask on the basis of the processing.

[0041] A monitoring system configured in this way is preferably configured to check the plausibility of the case differentiation and / or situation recognition by the pressure detection device, in particular an expiratory and / or inspiratory pressure detection device, by means of the processing, in particular a signal analysis, by the control unit. For example, the monitoring system, in particular the control unit is configured to compare pressure levels and / or signal curves of pressure levels, in particular in relation to an ambient pressure and / or detected inspiration and / or expiration cycles. In clear terms, a face mask is not applied tightly or correctly if the measured value of the pressure detection device temporarily or continuously corresponds to the pressure level of the environment.

[0042] The ambient pressure can preferably be provided via a data interface described below and used by the control unit as a comparison value.

[0043] A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the pressure detection device.

[0044] According to a preferred development of the invention, it can be provided in a monitoring system that the detection device, the input detection device, the output detection device and / or the pressure detection device comprise at least one coupling interface for coupling to the face mask. The monitoring system according to the invention is preferably to be understood as a retrofit monitoring system.

[0045] The monitoring system is preferably configured for detachable coupling to the face mask via the coupling interface. The detachable coupling is preferably to be understood as a tool-free detachable coupling.

[0046] Known respirator masks mostly have interfaces for, for example, filter mountings and / or supply tubes for inhalation. Additionally or alternatively, known respirator masks usually have standardized expiration openings, interfaces and / or valves, and therefore the monitoring system, in particular the coupling interface, can be advantageously adapted to known standards.

[0047] The coupling interface is preferably configured as an adapter for the face mask or for the breathing tubes of the face mask. Via the coupling interface, at least some portions of the detection device, the input detection device, the output detection device and / or the pressure detection device can preferably be arranged on and / or in and / or fastened to the face mask and / or the breathing tubes of the face mask.

[0048] Preferably, the monitoring system comprises multiple coupling interfaces, for example one coupling interface each for the input detection device, the output detection device, and the pressure detection device. Alternatively, the monitoring system comprises a single, common coupling interface. For example, the coupling interface is configured as a rotary lock, plug-in connection, bayonet lock, clip connection and / or press fit.

[0049] The coupling interface advantageously allows the monitoring system to be retrofitted to existing face masks, in particular without interfering with the configuration of the face masks. A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the coupling interface.

[0050] According to a preferred development of the invention, it can be provided in a monitoring system that the control unit comprises a storage device, wherein the storage device is configured to store the at least one signal detected by the detection device, the input detection device and / or the output detection device and / or the pressure detected by the pressure detection device.

[0051] A monitoring system configured in this way is advantageously configured to detect, process and store the at least one signal. The monitoring system is therefore advantageously independent in its function and allows, for example, subsequent use and / or evaluation of the detected signals and data. The storage device represents an advantageous solution in particular for applications where an external data connection of the monitoring system is not guaranteed or is not continuously guaranteed.

[0052] In clear terms, the monitoring system is preferably to be understood initially as a data collection system and, by means of the storage device, allows subsequent further processing and / or evaluation of the detected signals and data. The storage device is preferably connected to the control unit, the detection device, the input detection device, the output detection device and / or the pressure detection device for data communication.

[0053] The storage device is preferably configured together with the control unit, for example on a common substrate and / or in a common main body and / or housing. A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the storage device.

[0054] According to a preferred development of the invention, it can be provided in a monitoring system that the control unit comprises a comparison device, wherein the comparison device is configured to compare the signal detected by the detection device, the input detection device and / or the output detection device and / or the pressure detected by the pressure detection device with comparison data.

[0055] The comparison data are preferably provided by the control unit and / or the storage device described above. Preferably, the comparison data are configurable by a user. The comparison data are preferably to be understood as a data set from theoretical or practical experiments or models and are used within the scope of the invention as comparative values for evaluating the at least one detected signal and / or pressure. Preferably, the comparison data are used for the case differentiation described above and allow an analysis of the at least one detected signal and / or pressure in relation to the comparison data by the comparison device. The comparison device is preferably configured as part of the control unit and / or arranged together with the control unit on a substrate and / or in a common main body and / or housing.

[0056] A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the comparison device.

[0057] According to a preferred development of the invention, it can be provided in a monitoring system that the control unit comprises an input data interface, wherein the input data interface is configured to be coupled to external sensor devices for data communication. Within the scope of the invention, the input data interface serves to feed data from external sensor devices into the monitoring system. For example, the input data interface is configured to couple an environmental sensor device, a user sensor device, a tool sensor device and / or a motor vehicle sensor device to the monitoring system according to the invention for data communication.

[0058] The external sensor devices preferably provide the monitoring system, in particular the control unit, with data that can be used, for example, for processing the at least one detected signal, the detected pressure, for monitoring the use of the face mask and / or for comparison by the comparison device. For example, a separate sensor device provides data on an ambient pressure of the environment of the monitoring system.

[0059] The input data interface allows separate and / or external sensor devices to be added advantageously, in particular subsequently and / or varyingly, to the monitoring system.

[0060] The input data interface is preferably connected to the control unit for data communication. A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the input data interface.

[0061] According to a preferred development of the invention, it can be provided in a monitoring system that the monitoring system, in particular the detection device, the input detection device, the output detection device, the pressure detection device and / or the control unit, is mobile and / or coupleable at least in some portions. As described above, the monitoring system according to the invention is preferably to be understood as a retrofit monitoring system.

[0062] Preferably, the monitoring system comprises an energy storage device for storing and providing energy to the monitoring system in order to allow independent operation of the monitoring system.

[0063] Preferably, the monitoring system is configured to be portable by a user, for example in a breast pocket.

[0064] Due to its mobile configuration and design, the monitoring system preferably has a particularly small installation space requirement in order to affect the user's freedom of movement as little as possible. Preferably, the monitoring system is detachably coupleable to a face mask, an upper body harness and / or an equipment suit.

[0065] A monitoring system configured in this way is particularly advantageous because the use of a face mask can be monitored in a particularly simple manner by means of the configuration of the monitoring system that is mobile and / or coupleable at least in some portions.

[0066] According to a preferred development of the invention, it can be provided in a monitoring system that the monitoring system comprises a provision data interface, wherein the provision data interface is configured to provide the at least one signal detected by the detection device, the input detection device and / or the output detection device and / or the pressure detected by the pressure detection device.

[0067] Within the scope of the invention, the provision data interface serves to provide the detected, processed and / or stored signals and / or data of the monitoring system. The provision is made, for example, to a separate logic unit, storage unit and / or server unit. The provision data interface preferably allows a transfer of the data of the monitoring system to other devices separate from the monitoring system. In clear terms, the provision data interface allows, for example, the use of a docking station, wherein the provision data interface can be connected to the docking station, and thus data transfer from the monitoring system is made possible.

[0068] Optionally, the provision data interface also allows data transfer to the monitoring system, for example the comparison data described above. The provision data interface is preferably separate from the previously described input data interface. A monitoring system configured in this way is particularly advantageous because the data provision interface makes it possible to monitor the use of a face mask and to provide the detected signals and data in a particularly simple manner.

[0069] According to a preferred development of the invention, it can be provided in a monitoring system that the monitoring system comprises an output device, wherein the output device is configured to output at least one prompt, in particular wherein the prompt can be output on the basis of the signal detected by the detection device, the input detection device and / or the output detection device and / or on the basis of the pressure detected by the pressure detection device. The output device is preferably configured for the visual, optical, haptic and / or acoustic output of at least one prompt. The output device is preferably configured as a vibration device. In the context of the invention, a prompt is to be understood, for example, as a prompt for the correct application of the face mask. The prompt is configured, for example, as a defined sequence of outputs, in particular vibrations, by the output device. For example, the monitoring system with the output device allows a simple prompt for the correct application of the face mask or else for breathing exercises for the user.

[0070] For example, a monitoring system configured in this way allows the initiation and / or coordination of procedures by the user on the basis of a predefined schedule and / or upon the occurrence of certain predefined events in practice, as well as corresponding monitoring and / or recording of compliance with the procedures. Using the upgrading of the monitoring, the monitoring system suggests, for example, an alternative prompt and / or repetitions of the previous prompt.

[0071] The prompts are preferably made on the basis of the signal detected by the detection device, the input detection device and / or the output detection device and / or on the basis of the pressure detected by the pressure detection device and / or on the basis of a comparison that has been carried out.

[0072] The prompts are preferably made by the control unit. For this purpose, the output device is preferably connected to the control unit for data communication. A monitoring system configured in this way is particularly advantageous because the output device makes it possible to monitor the use of a face mask and to interact with a user on the basis of the monitoring in a particularly simple manner.

[0073] According to a second aspect of the invention, the object is achieved by a mask system comprising a face mask and a monitoring system according to the first aspect. The described mask system offers all the advantages already described for the monitoring system according to the first aspect of the invention. The face mask preferably comprises a counterpart interface for detachable coupling to the coupling interface.

[0074] The face mask is preferably configured as a respirator mask. The face mask is configured as a full mask or half mask. The face mask is preferably configured for arrangement, in particular for sealing arrangement, on a user's face. The arrangement on the user's face preferably comprises covering the user's mouth and / or nose with the face mask. The face mask preferably comprises at least one breathing tube for the fluid-communicating supply and / or discharge of respiratory gases to and / or from the face mask.

[0075] Within the scope of the invention, the at least one breathing tube is defined as a part of the face mask and / or of the monitoring system. A mask system configured in this way is particularly advantageous because the monitoring system allows monitoring, in particular retrofitted monitoring, of the use of the face mask in a particularly simple and advantageous manner.

[0076] According to a third aspect of the invention, the object is achieved by the use of the monitoring system according to the first aspect with a face mask. The described use offers all the advantages already described for the monitoring system according to the first aspect of the invention or for the mask system according to the second aspect of the invention.

[0077] According to a fourth aspect of the invention, the object is achieved by a method for monitoring the use of a face mask by means of a monitoring system. The monitoring system is in particular configured according to the first aspect. The method comprises: - detecting at least one signal of at least one gas flow of the face mask by means of a detection device of a monitoring system, - processing the signal detected by the detection device by means of a control unit of the monitoring system, - monitoring the use of the face mask on the basis of the processing.

[0078] The described method offers all the advantages already described for the monitoring system according to the first aspect of the invention or for the mask system according to the second aspect of the invention.

[0079] Unless explicitly stated otherwise, the method steps described above and below can be carried out individually, together, once, multiple times, simultaneously and / or sequentially in any order. A designation as, for example, "first method step" and "second method step" does not imply any chronological order and / or prioritization. A preferred sequence of method steps stipulates that the method steps are carried out in the listed order.

[0080] The detection preferably comprises detecting a signal of an input gas flow into the face mask by means of an input detection device of the monitoring system, detecting a signal of an output gas flow from the face mask by means of an output detection device of the monitoring system and / or detecting a pressure within the face mask by means of a pressure detection device of the monitoring system.

[0081] Furthermore, the method preferably comprises providing the detected and / or processed signals and / or data via the provision data interface of the monitoring system.

[0082] Furthermore, the method preferably comprises comparing the signal detected by the detection device, the input detection device and / or the output detection device and / or the pressure detected by the pressure detection device with comparison data.

[0083] Furthermore, the method preferably comprises receiving data from at least one external sensor device through the input data interface, in particular wherein the data from the at least one external sensor device are processed by the control unit in order to monitor the use of the face mask.

[0084] A method configured in this way is particularly advantageous because the monitoring system allows monitoring, in particular retrofitted monitoring, of the use of the face mask in a particularly simple and advantageous manner.

[0085] According to a fifth aspect of the invention, the object is achieved by a computer program product for monitoring the use of a face mask by the monitoring system according to the first aspect or by the mask system according to the second aspect. The computer program product comprises commands that cause the monitoring system or mask system to carry out the method according to the fourth aspect. The described computer program product offers all the advantages already described for the monitoring system according to the first aspect of the invention, for the mask system according to the second aspect of the invention, or for the method according to the fourth aspect of the invention.

[0086] Thus, a computer program product according to the invention offers the same advantages as those already described in detail with reference to a method according to the invention. The method can in particular be a computer-implemented method. The computer program product can be implemented as computer-readable instruction code in any suitable programming language, such as JAVA, C++, C# and / or Python. The computer program product can be stored on a computer-readable storage medium such as a data disk, a removable drive, a volatile or non- volatile memory, or built-in memory / processor.

[0087] The instruction code can influence or control a computer or other programmable devices, such as a computing unit of a detection device, in such a way that the commands are executed. Furthermore, the computer program product can be made available in a network such as the Internet, from which it can be downloaded by a user when needed. The computer program product can be implemented using software and using one or more special electronic circuits, i.e., in hardware or in any hybrid form, i.e., using software components and hardware components.

[0088] According to a sixth aspect of the invention, the object is achieved by a computer- readable medium on which the computer program product according to the fifth aspect is stored. The described computer-readable medium offers all the advantages already described for the computer program product according to the fifth aspect of the invention or for the method according to the fourth aspect of the invention.
