Description

[0001] The invention relates to a device for the optoelectronic recording of corona discharges on objects, in particular at the so-called terminal points, i.e. the fingertips and / or toetips.

[0002] A corona discharge is an electrical discharge caused by a weak current flow in liquids and / or gases. It can occur at electrodes between which a high voltage drops, creating a resulting electric field strength sufficient to ionize the surrounding fluid. One of the two electrodes can be at ground potential.

[0003] Corona discharges, after their qualitative and quantitative analysis, are suitable for making certain statements about the object in which they occur. Corona discharges are used in various fields of chemistry, physics, and medicine, including trace analysis, testing material properties, and thus inferring the physical and chemical properties of the object.

[0004] Such devices for recording corona discharges on objects are known from the documents DE 37 07 338 C2, DE 198 20 609 A1, DE 10 2007 008 673 A1, EP 1 962 151 B1, DE 31 11 929 A1 and DE 38 24 564 A2.

[0005] Since the optical images of the corona discharges recorded in this way can only be evaluated manually, this represents a significant disadvantage of the known devices. In addition, the recordings of corona discharges must be carried out under darkroom conditions with the devices known from the state of the art, since the corona discharges are very faint and daylight disrupts the recording process or even makes it impossible due to overexposure.

[0006] However, with the device described here, it is particularly advantageous for the evaluation of recorded corona discharges on objects if all fingertips and / or toetips are recorded simultaneously. If the fingertips and / or toetips are recorded individually and sequentially, the recording conditions can change during the recording process to such an extent that reproducible evaluation of the recordings is significantly more difficult. Automated, semi-automated, and reproducible recording is not possible in this way. Furthermore, for automated, semi-automated, and reproducible recording of the objects, it must be ensured that the terminal points of the fingertips and / or toetips to be examined are fixed at specific locations. Otherwise, the recorded corona discharges would have to be assigned to specific fingers or toes manually.

[0007] The recording and evaluation of such corona discharges must be carried out under comprehensible and reproducible conditions of the respective measurement in order to help such methods achieve scientific recognition.

[0008] Accordingly, the object of the invention is to provide a device for the simultaneous, optoelectronic recording of corona discharges on several arbitrary objects and their automated and semi-automated evaluation, which avoids the known disadvantages of the prior art and which enables automated or semi-automated and reproducible recording and evaluation.

[0009] How this object is achieved according to the invention results from the features of the main claim, further advantageous embodiments and further developments of the invention result from the subclaims.

[0010] This problem is solved by a device for the simultaneous recording of corona discharges on multiple biological and non-biological objects and their automated and semi-automated evaluation. The corona discharges are recorded optoelectronically. The device records the corona discharges occurring on any biological object, in particular on human body parts, such as fingertips, toetips, and the balls of the feet. The device contains a dielectric plate, in particular a transparent plate, on one side of which is a high-voltage electrode. The high-voltage electrode is connected to the high-voltage pole of a high-voltage generator. The side of the plate opposite the high-voltage electrode forms a recording area for the objects to be recorded. This recording area serves as a contact area for supporting the objects.The device comprises an arrangement for optically recording discharges that occur between the high-voltage electrode and the objects under investigation. The device also includes a component for aligning the objects. This component is located on the plate side of the recording area.

[0011] A preferred embodiment of the device is one in which the components for receiving or aligning the objects, hereinafter referred to as the template, are arranged interchangeably on the front of the device plate. The device preferably has components for securing the template for receiving or aligning the objects, which allow the template to be exchanged. For interchangeable fastening, a magnetic holding device, a mechanically designed holding device, for example, a clamp fastener or a hook-and-loop fastener, can be used.

[0012] Preferably, the stencil covers the entire surface of the plate. In a preferred embodiment, the stencil projects beyond the plate in a plane-parallel manner. The projecting edge is preferably designed as a receiving area, in particular as a support surface, for the stencil.

[0013] The use of the template enables the assignment of the objects to be recorded, in particular the fingertips and / or toetips, to a specific position on the plate or the recording area. Each object, in particular each of the fingertips and / or toetips, is thus assigned a specific, defined position in the recording area, in particular the support surface. To implement automated or semi-automated evaluation and detection of the corona discharges formed on the objects to be examined, in particular on the fingertips and / or toetips, it is necessary that the objects, in particular the fingertips and / or toetips, are fixed at specific positions in the recording area.

[0014] Preferably, the automatic recognition of the objects, in particular the fingertips and / or toetips, is carried out by appropriate software, which is preferably located on an external computer.

[0015] A preferred embodiment of the device is characterized in that the plane of the template is plane-parallel to the plane of the plate at a defined distance. Therefore, a gap is preferably arranged between the plate and the template. The distance between the plate and the template is preferably a few centimeters. The distance between the plate and the template is particularly preferably 0.3 to 1.2 cm.

[0016] In a particularly preferred embodiment, the stencil rests in a light-tight manner on an edge surrounding the receiving area or support surface. A sealing component is preferably arranged between the surrounding edge and the stencil, thereby ensuring a substantially light-tight seal of the space between the surrounding edge and the stencil. This sealing element is preferably elastic to compensate for any unevenness of the object being recorded.

[0017] To ensure a uniform distance from the plate, the template can also preferably have several spacers distributed across the entire surface of the template. The length of the spacers determines the distance between the plate and the template.

[0018] A further preferred embodiment of the device is characterized in that the plate and the template are manufactured as an integrated component. In this embodiment, the template is integrated into the plate. The template is formed, for example, by recesses in the plate. These recesses serve to accommodate the object to be examined.

[0019] In a particularly preferred embodiment of the device, the template contains several openings for accommodating the fingertips and / or toe tips to be recorded. These openings are preferably circular or oval. The respective fingertips and / or toe tips can be passed through the openings in the template. Preferably, there is a separate opening for each finger or toe.

[0020] Another particularly preferred embodiment of the device is characterized in that there are openings in the upper region of the template for the passage of the fingertips and there are two larger openings in the lower region of the template which allow the toes and the balls of the left and right feet to rest on them simultaneously.

[0021] The template's openings are preferably spaced laterally apart. To allow the fingertips and / or toes to easily pass through the template's openings, the openings for the fingers of a hand and the toes of a foot are spaced a few millimeters to a few centimeters apart.

[0022] In a preferred embodiment of the device, the template has ten openings for the fingertips of the person being examined to pass through. Five openings each for receiving the fingertips of one hand are preferably arranged in an ergonomically adapted manner. To allow easy insertion of the fingertips of one hand, the openings are preferably arranged in an ergonomically adapted manner. The openings are preferably arranged such that the fingers of the person being examined can be easily passed through the openings.

[0023] In a preferred embodiment of the device, the openings for the fingers of the right hand, arranged in an ergonomic shape, and the openings for the fingers of the left hand, arranged in an ergonomic shape, are laterally spaced from each other. Preferably, the openings arranged in an ergonomically favorable shape are arranged mirror-symmetrically to each other with respect to a vertical axis of symmetry in the center of the template.

[0024] In a particularly preferred embodiment of the device, the stencil is made of a transparent material. The stencil is preferably made of glass, acrylic glass, or other preferably transparent materials. The stencil must be made of an electrically insulating material.

[0025] A further preferred embodiment of the device comprises at least one reference electrode for aligning the objects, in particular the fingertips and / or toetips, on the recording area or the support surface. Preferably, at least one reference electrode is arranged on the template. The reference electrode or reference electrodes are located on the side of the template facing the recording surface of the high-voltage electrode. When recording the corona discharges of the objects, in particular the fingertips and / or toetips, the corona discharges forming at the reference electrode(s) are also optically recorded. The corona discharges forming at the reference electrode are known or can be determined in advance, depending on the electrode material and the measurement conditions.The corona discharges of the objects, especially the fingertips and / or toetips, can be qualitatively and quantitatively compared with the corona discharges formed at the reference electrode and thus standardized. Using a reference electrode, the corona discharges of the objects, especially the fingertips and / or toetips, can thus be quantitatively recorded and determined using suitable evaluation algorithms in the software used.

[0026] In a further preferred embodiment of the device, the type of device or template for aligning the objects, in particular the fingertips and / or toe tips, can be identified via the position and / or the shape of the reference electrode and / or the number of reference electrodes. The device for aligning the objects or the type of template, in particular the fingertips and / or toe tips, can preferably be identified via the position and / or the shape of the reference electrode and / or the number of reference electrodes. The arrangement of the openings and / or the size of the openings and / or the spacing of the openings of a template are preferably adapted to specific hand sizes or foot sizes. By using different template types, the device can be adapted to the respective size and shape of the objects or the hand size or foot size of the person to be examined.The type of template used can be easily assigned or identified by the position and / or shape of the reference electrode and / or the number of reference electrodes.

[0027] In a further preferred embodiment of the device, the template has at least one identifying feature formed by one or more depressions and / or elevations and / or by one or more colored markings and / or by one or more characters. This feature, in addition to identifying the template by the position and / or number of reference electrodes and / or the shape of the reference electrode, represents a further identifying feature for the template used.

[0028] In a preferred embodiment of the device, the high-voltage electrode consists of a clear, transparent, electrolytic liquid, wherein the electrolytic liquid is enclosed between two clear, transparent dielectric plates. The two clear, transparent dielectric plates are plane-parallel to one another at a distance of preferably a few millimeters to one centimeter from each other and are bonded together at their edges in a watertight manner, preferably with a suitable adhesive. One of the two dielectric plates forms the receiving area, in particular the support surface, for the objects to be examined, in particular the fingertips and / or toe tips. The dielectric plate forming the receiving area, in particular the support surface, is preferably arranged on the outside.This dielectric plate corresponds to the previously described plate of the device on one side of which the high-voltage electrode is arranged.

[0029] The electrolytic fluid preferably contains copper sulfate dissolved in a mixture of water and alcohol. Copper sulfate exhibits good electrical conductivity. Furthermore, the electrolytic fluid is preferably permanently preserved by the copper sulfate and alcohol it contains, preventing biological growth by algae and fungi in the long term.

[0030] In a further preferred embodiment of the device, the recording area, in particular the space between the template and the support surface of the plate, is ventilated. The housing of the device preferably has a ventilation device by means of which the recording area or the support surface of the plate is ventilated. By ventilating the recording area or the space between the recording area or the support surface and the back of the device for positioning the objects or the template, the measuring conditions, e.g. the air humidity, for recording the corona discharges on the objects, in particular on the fingertips and / or toetips, can be kept constant or within a defined range. For automated or semi-automated and reproducible recording orWhen evaluating the corona discharges on the objects, especially on the fingertips and / or toetips, it is necessary that the measurement conditions are kept as constant as possible or lie within a defined range for reproducibility.

[0031] In a further embodiment of the device, the recording area and in particular the support surface of the plate is heated. The heating of the recording area or the support surface of the plate can be achieved, for example, by a heating device that warms up the air sucked in via the ventilation device of the template and then feeds it to the recording area. This counteracts condensation of moisture in the recording area. In a further embodiment of the device, the air can be dried before entering the recording area or the support surface on the plate by means of a device for removing air humidity, which is integrated in the ventilation device. Pre-dried incoming air can absorb more moisture from the objects to be examined, in particular the fingertips and / or toes. The condensation of moisture in the recording area oron the support surface is largely prevented.

[0032] In a preferred embodiment of the device, the device has a housing. Some or all of the housing's parts are formed by an electrically conductive layer on the inside of the housing, and some or all of the housing's parts are formed by an electrically insulating layer on the outside of the housing. The electrically conductive layer on the inside of the housing is preferably made of stainless steel or another suitable metallic material. In a particularly preferred embodiment of the device, the electrically conductive layer on the inside of the housing is made of adhesive aluminum foil. The electrically conductive layer on the inside effectively shields the interference generated by the high-voltage generator from the outside. In addition, the electrically conductive layer on the inside of the housing forms the electrical ground pole.An electrically insulating layer is arranged on the outside of the housing to ensure electrical insulation from the outside. The electrically insulating layer is preferably made of an electrically non-conductive plastic such as acrylic glass or other materials that can be used for this purpose.

[0033] A further preferred embodiment of the device is characterized in that a device is arranged in the region of the receiving area, or the support surface opposite the template, and / or in front of the template itself, which receives at least the objects to be examined, in particular the fingertips and / or toetips, and covers the receiving area, in particular the support surface, as light-tight as possible. This device is referred to below as a cuff.

[0034] The cuff has openings for the light-tight insertion of the objects, in particular the hands and / or feet. The cuff is preferably designed such that the objects, in particular the feet and / or hands, can be inserted into the cuff and then the cuff can be sealed light-tight. This allows the device to be used even under daylight conditions, eliminating the need for darkroom conditions.

[0035] An arrangement for evaluating the corona discharges on objects, in particular on fingertips and / or toetips, recorded by a previously described device comprises at least one of these devices and a computing unit to which the device or devices are connected. The computing unit preferably consists of a PC. Software or a program runs on the computing unit, by means of which the corona discharges on objects recorded by the device or devices are analytically evaluated. Preferably, the at least one device is connected to the computing unit via a data line. The data line can be wired or wireless, for example in the form of a radio transmission. Preferably, the evaluation of the recorded corona discharges is carried out semi-automatically or automatically by the program. Preferably, manual intervention in the program sequence is possible.Preferably, the control electronics arranged in the device can be controlled via the program or parameters for controlling the camera, the lens, the lighting of the recording area, the fan, the heater and the high-voltage generator, etc. in the device can be changed via the program.

[0036] According to the invention, the previously described embodiments of the device for optically recording corona discharges on objects, in particular on fingertips and / or toetips, enable automated or semi-automated and reproducible recording and subsequent evaluation of the recorded corona discharges. By using a template, the objects to be examined, in particular the fingertips and / or toetips, can be fixed at defined positions, which are recognized by the software for evaluation.

[0037] The following description sets out further advantages, features and details of the invention, in which various embodiments are explained in detail with reference to the drawings.

[0038] They show: Fig. 1 a sectional view of a device according to the invention, Fig. 2 a vertical view of an embodiment of a template for receiving the fingertips and / or the toe tips, Fig. 3 a model of the physical processes involved in the formation of corona discharges on an object, Fig. 4 a frame with two devices according to the invention for the hands and feet, Fig. 5 a lifting system with a device according to the invention for the hands and feet, and Fig. 6 a photograph of the corona discharges at the terminal points or fingertips of a hand.

[0039] In section view, Fig. 1 shows a device (1) according to the invention for optically recording corona discharges on objects, in particular on fingertips and / or toetips. The device (1) consists of a housing (2) in which a recording arrangement (3) for optically recording corona discharges on objects is arranged. The objects, in particular the fingertips and / or toetips, are placed on a recording area or a support surface (4) of a plate (5). On the side of the plate (5) facing away from the recording area or support surface (4) there is a high-voltage electrode (6) which is connected to one pole of a high-voltage generator (7).

[0040] In the illustrated embodiment of the device (1), the high-voltage electrode (6) is formed by two dielectric plates (61, 62) between which an electrolytic liquid (63) is located, which is connected to a pole of the high-voltage generator (7) via an electrically insulated cable (71). The high-voltage electrode (6) is connected to the housing (2) via the dielectric plates (61, 62). The dielectric plate (61) of the high-voltage electrode (6), arranged on the outside of the device (1), simultaneously forms the plate (5) of the device (1).

[0041] A device (8) for aligning the objects, in particular the fingertips and / or toetips, is arranged in the form of a template (9) at a distance parallel to the recording area or the support surface (4). The template (9) has a plurality of openings (91). Figure 2 shows and describes an embodiment of the template (9) in detail.

[0042] A cuff (10) is attached in front of the template (9), which seals the receiving area or support surface (4) and the template (9) to a certain extent from light. This cuff (10) for receiving the hands or feet has one or more openings (111) through which the hands and / or feet and / or other objects can be inserted. The insertion openings (111) can be enclosed in a light-tight manner around the wrists or ankles, or around the hands or feet themselves. The openings (111) have, for example, a hook-and-loop fastener, with which the cuff can be used to surround the wrists and ankles to a certain extent from light. The template (9) itself is preferably attached to the device (1) in a light-tight manner. For this purpose, an additional sealing element can be provided between the template (9) and the housing (2) of the device (1), which is not shown in the embodiment of the device (1) shown in Figure (1).

[0043] The recording arrangement (3) for recording the corona discharges consists of a camera (31) and a lens (32) that is aligned with the recording area or the support surface (4). With the help of the recording arrangement (3), the corona discharges forming on the objects, in particular on the fingertips and / or toetips, can be optically recorded. The camera (31) and / or the high-voltage generator (7) are controlled via control electronics (11) that are arranged in the housing (2) of the device (1). The device (1) communicates with an external evaluation computer unit, for example in the form of a PC, via a data interface that is preferably integrated in the control electronics (11) or preferably in the camera (31). Furthermore, other components of the device (1) can be controlled via the control electronics (11), e.g.a fan (13), an interior light, a heater, and in particular recording parameters such as the exposure time and the gain of the camera (31), the pulse shape and the pulse height of the high voltage. The camera (31), the lens (32), and the control electronics (11) are arranged in a rear region of the housing (2) separated by a partition (12). The partition (12) has an opening at which the lens (32) is arranged with the light inlet side. The lens (32) is adjusted so that the camera (31) can record the entire recording area or the support surface (4).

[0044] In order to be able to record the optically recorded corona discharges on the objects, in particular the fingertips and / or the toetips, under measurement conditions that are as consistent and reproducible as possible, the device (1) has a ventilation device. The ventilation device comprises a fan (13) which ventilates the recording area or the support surface (4) via a ventilation duct (14). The fan (13) is preferably arranged such that the air in the area of ​​the fan opening (23) in the housing (2) is sucked in by the fan (13) and flows via the ventilation duct (14) through the recording area or along the support surface (4), flows through the openings (91, 91') in the template (9) and is discharged to the outside via the opening (111) in the sleeve (10). This air flow above the recording area or the support surface (4) reduces the humidity that has accumulated on the fingertips ortoetips in the recording area or on the support surface (4) is dissipated. Condensation or precipitation of moisture in the recording area or on the support surface (4) is thereby substantially prevented. By substantially preventing condensation of moisture in the recording area or on the support surface (4), the quality of the recorded images is significantly improved because the dielectric plates (61, 62) thereby remain optically clear and transparent. In addition, it is achieved that the recording of the corona discharges can be carried out under defined and thus reproducible conditions, at least with regard to the moisture content of the objects, in particular at the fingertips or toetips.

[0045] To facilitate the positioning of objects, particularly fingertips and / or toetips, before recording corona discharges, an illumination device (17) is arranged in the housing (2). The illumination device (17) is switched on and off automatically before and after a recording, or manually if desired, via the control electronics (11).

[0046] To suppress the undesirable condensation of moisture from the objects, particularly from fingertips and / or toetips, before corona discharges are recorded on the plate (5) or the high-voltage electrode (6), a heating device (18) is arranged in the housing (2) to heat the plate (5). The heating device (17) is automatically switched on and off or regulated via the control electronics (11) to keep the temperature of the plate (6) constant. This heating device (18) according to the invention also contributes to the reproducibility of the measurement conditions.

[0047] The electrical voltage at the high-voltage electrode (6) creates a strong electric field above the insulating plate (5). If electrically conductive objects, such as metal objects, plant leaves, hands, feet, fingertips, or toes, are brought close to the plate (5), electrons escape from the object and move toward the plate (5). The escaping electrons generate the corona discharges recorded by the recording device (3). Fig. 3 the principle is shown and described in detail.

[0048] In Fig. Figure 2 shows a plan view of an embodiment of the device (8) for aligning objects, for example, the fingertips of two hands, in the form of a template (9). The template (9) has several openings (91, 91'). Five openings (91, 91') are assigned, for example, to the five fingers of one hand.

[0049] Five openings (91, 91') for each hand are arranged in an ergonomically favorable shape. In the illustrated embodiment of the template (9), the openings (91, 91') for the fingers of a hand are arranged in an ergonomically favorable shape, mirror-symmetrical to a vertical axis of symmetry AA'. The size of the openings (91, 91') and the distance between the openings (91, 91') from one another are preferably adapted to an average hand size. The template (9) is preferably attached to the device (1) according to the invention in an interchangeable manner, so that the openings (91, 91') of a template (9) can be provided for specific hand sizes. By exchanging the template (9), it can be easily adapted to the hand size or foot size of the person to be examined.

[0050] In the illustrated embodiment, a reference electrode (81) is arranged on the axis of symmetry (A-A') of the template (9). The reference electrode (81) is formed by a preferably circular metal disk (811). Corona discharges form on the metal disk (811) when a high voltage is applied to the high-voltage electrode (6). The metal disk (811) of the reference electrode (81) is arranged on the side of the template (9) facing towards the support surface (4). On the opposite side, the reference electrode (81) is preferably electrically insulated. The reference electrode (81) is connected to ground via an electrical conductor (82). The electrical conductor (82) is arranged, for example, in a recess, for example a groove, in the surface of the template (9).Alternatively, the electrical conductor (82) can also be formed by a metal strip, preferably a metal strip made of aluminum, glued to the surface of the template (9).

[0051] The shape of the reference electrode (81) can be different from that shown in Fig. 2. In an embodiment of the template (9) with two or more reference electrodes (81), the distance between two reference electrodes (81) can be used for the qualitative evaluation of the optically recorded corona discharges. The distance between two reference electrodes (81) is fixed, so that the size of the recorded corona discharges can be determined in relation to this distance. The position of the reference electrode (81) is not limited to the Fig. 2. Preferably, the reference electrode (81) is sufficiently far apart from the fingertips inserted into the openings (91, 91') so that no unwanted discharge can occur between the fingertips and the reference electrode (81).

[0052] The template (9) can be identified by the position of the reference electrode (81) on the template (9) and / or by the shape of the reference electrode (81) and / or by the number of reference electrodes (81). Furthermore, the preferably replaceable template (9) can be identified by a further identification feature (93) applied to the template (9). The further identification feature (93) can be formed, for example, by one or more elevations and / or depressions and / or by one or more characters and / or by one or more color markings. In the Fig. In the template (9) shown in Figure 2, the additional identification feature (93) is formed by the image of the Roman numeral VI. The position of the identification feature (93) can be located either within the receiving or support surface (4) of the corona discharges or outside, at the edge of the template (9).

[0053] In Fig. Figure 3 schematically illustrates the formation of corona discharges at a fingertip (100). Using positive high-voltage pulses as an example, the formation of the luminous phenomena occurring in the Kirlian effect is described.

[0054] The electrons (103) occur preferentially at the places of the biological object, in the Fig. 3, using the example of a finger (100), where light energy is stored in excited atomic and molecular states (bioplasm). This results in field emission (101). As they fly through the air toward the metal plate, the released electrons collide with air molecules, exciting them to glow – this is collision excitation (104). The photons emitted by the excited air molecules (105) illuminate an electronic recording medium, thus creating a so-called Kirlian image.

[0055] At locations in the biological object where there is little bioplasm, there are fewer electrons in excited atomic and molecular states, but rather in ground states (102). The energy available from the electric field of the high-voltage electrode (3) is insufficient to release electrons (103). Such locations are then visible as gaps in the Kirlian image. The distribution of free electrical charges (electrons) can be determined using electrically positive high-voltage pulses.

[0056] In Fig. Figure 4 shows a frame (15) with two devices (1, 1') according to the invention for recording the corona discharges on the hands and feet. The lower device (1') is used to record the corona discharges on the feet. The upper device (1') is used to record the corona discharges on the hands. The frame (15) is preferably provided with rollers (16, 16') for moving the frame (15) with the devices (1, 1'). The frame (15) is preferably provided with an electrically insulating layer on its surface.

[0057] In Fig. 5, a device (1) for recording corona discharges, in particular for recording corona discharges at the fingertips and / or toetips, is arranged on a lifting device (16). Using the lifting device (16), the height of the device (1) can be adjusted to different heights, thus allowing it to be positioned in ergonomically favorable positions, for example, to examine a person's hands or fingertips and / or a person's feet or toetips with the device (1).

[0058] In Fig. Figure 6 shows an example of a recording of corona discharges at the fingertips of a hand. The corona discharges are visible as bright coronas of radiation around the fingertips. Depending on the formation, size, and shape of the corona at the respective fingertips, conclusions can be drawn about the amount of electromagnetic energy (bioplasma) of the person being examined.
