[0003] Agricultural sprayer

[0004] The invention relates to an agricultural spraying or spraying machine for applying a spraying agent.

[0005] These agricultural machines are used to apply a liquid spray or spraying agent on the farm using a spraying system. These are typically water-based sprays, to which one or more liquid additives are mixed, for example, chemical and / or biological additives.

[0006] The agricultural spraying machine typically has a frame on which machine components are arranged or mounted, in particular the spraying system, which is designed to receive spraying agents, especially water with or without spray additives, in a tank and to apply them by means of spraying or spraying.

[0007] Special care must be taken when handling liquid spray additives, as these are often chemical or biological liquids classified according to hazard classes, especially in concentrated form. Unintentional skin contact can therefore lead to problems for the user or operator of the agricultural sprayer. It has therefore been proposed to supply chemical spray additives using a closed transfer system. In this system, the liquid spray additive is provided in a container which, in conjunction with a transfer system, is designed to safely supply the additive from the container to the spraying system of the agricultural sprayer, ensuring that no liquid additive escapes unintentionally.

[0008] A closed transfer system is known, for example, from document WO 2023 / 194918 A1. In this example, the closed transfer system has a mobile and portable transfer container in which the liquid spray additive is held. One or more fluid connections can be established with the spray system of the agricultural sprayer via a coupling device of the closed transfer system, in order to safely transfer the spray additive from the mobile transfer container to the BOEHMERT & BOEHMERT spray system.

[0009] - 2 - to transfer and, conversely, optionally to transfer a rinsing agent for rinsing the mobile transfer container from the spray system to the transfer container, in particular water.

[0010] The object of the invention is to provide an improved agricultural spraying machine for applying a spraying agent, which supports and facilitates efficient and safe interaction with a closed transfer system for providing a liquid spraying agent additive.

[0011] The solution is an agricultural spraying machine for applying a spraying agent according to independent claim 1. Embodiments are the subject of dependent claims 2 to 15.

[0012] According to one aspect, an agricultural sprayer is designed for applying a spraying agent and comprises the following: a frame; a spraying system mounted on the frame and configured to receive a spraying agent in a tank and apply it by means of spraying; a coupling device; and a receiving device with a holding device on a transfer device. The coupling device is connected to the spraying system via a fluid line and can be detachably coupled to an associated coupling device of a closed transfer system, which has a mobile transfer container for providing a liquid spraying agent additive that can be mixed with the spraying agent in the spraying system for application.The coupling device is further configured to form a fluid connection by coupling to the associated coupling device, through which the liquid spray additive can be supplied from the mobile transfer container to the spray system. The receiving device is configured to detachably position and hold the mobile transfer container on the transfer device for transferring the liquid spray additive from the mobile transfer container to the spray system. The transfer device, on which the holding device is located, is configured to move it between a working position, in which the mobile transfer container can be positioned on the holding device for transferring the liquid spray additive, and a transport position, in which the holding device is free of the mobile transfer container. BOEHMERT & BOEHMERT.

[0013] - 3 -

[0014] The receiving device allows the mobile transfer container, which may be designed as a portable mobile transfer container, to be detachably arranged and held on the holding device of the transfer unit for the purpose of transferring the liquid spray additive. The transfer unit allows the holding unit to be moved into the working position, in particular such that the mobile transfer container can then be positioned on the holding unit safely and with minimal effort for the user, and is easily accessible. However, if no mobile transfer container is attached to the holding unit, the transfer unit can be moved into the transport position with the aid of the transfer unit, in order to store the holding unit, for example, in a space-saving manner on the agricultural sprayer, for example, for road transport of the agricultural sprayer.The transfer device with its attached holding device can, in the transport position, be positioned, for example, adjacent to components of the spraying system and / or partially between them. Overall, this increases safety when operating the agricultural sprayer.

[0015] The agricultural sprayer can be designed to be coupled to and towed by a tractor. Alternatively or additionally, the agricultural sprayer can be mounted on a tractor and carried by it, for example, at the rear. With this type of agricultural sprayer in particular, the challenge lies in designing a space-saving mounting system and ensuring user-friendly handling of the mobile transfer tank, which is facilitated by the proposed mounting system. A design for the agricultural sprayer as a self-propelled agricultural vehicle is also possible.

[0016] The relocation device can be locked in different relocation positions, in particular the working position and / or the transport position, thereby preventing or at least hindering unintentional relocation from the respective position. A locking device provided for this purpose can include a manually operated locking mechanism, for example, a locking screw. BOEHMERT & BOEHMERT

[0017] - 4 -

[0018] The receiving device with the holding device on the transfer device can be arranged at the rear of the agricultural sprayer, whereby the holding device can be positioned at the rear or laterally, for example, in the working position.

[0019] The coupling device connected to the spray system via the fluid line, as well as the associated coupling device of the closed transfer system, which in turn may be connected to an interior of the mobile transfer container via one or more fluid lines, may be configured to form a plug connection. For this purpose, respective plug connection elements may be provided on the coupling device and the associated coupling device. If such a plug connection is provided, its configuration establishes the fluid connection for transferring the liquid spray additive from the mobile and optionally portable transfer container to the spray system.

[0020] One or more of the fluid lines can be designed as flexible fluid lines. Fluid lines can also be configured as hoses or pipes.

[0021] The holding device can be arranged in an extended position during operation and in a retracted position during transport. The extended and retracted positions can correspond to unfolded and folded positions of the transfer device, respectively. This is achieved by moving one or more transfer components of the transfer device relative to each other, i.e., extending or retracting them. These transfer components can, for example, be moved and / or pivoted relative to each other.

[0022] The holding device can be positioned distally relative to the frame in the working position and proximally in the transport position. The holding device can be positioned distally / proximally relative to the spraying system, particularly relative to the tank. If the spraying system has a secondary or auxiliary tank for holding the liquid spray additive, the holding device can be positioned distally / proximally relative to the secondary / auxiliary tank in both the working and transport positions.

[0023] The holding device can be stored in the transport position inside a protective housing which is connected to the frame, and in the working position outside the protective housing. BOEHMERT & BOEHMERT

[0024] - 5 - The protective housing can be arranged on multiple sides or on one side, surrounding the interior of the housing. For example, the protective housing can be open on one underside, for instance, to allow one or more fluid lines to exit. The protective housing can be configured to at least partially protect and contain one or more elements or components of the spray system, at least when the protective housing is closed. In one embodiment, the protective housing can be arranged adjacent to the auxiliary / additional tank, which optionally contains the liquid spray additive, and / or at least partially surround it.

[0025] The transfer mechanism can extend through an opening in the protective housing, which can be closed by means of a housing door, when in the working position. The housing door can be used to open or close the opening. With the housing door open, the operator or user may, for example, be able to access elements of the spraying system, whereas this is prevented when the housing door is closed. The housing door can be closed, for example, when the transfer mechanism is in the working position. The transfer mechanism is then retracted into the protective housing and stored there, particularly when not in use, i.e., when no mobile transfer container is in the container holder, for example, during road transport of the agricultural sprayer. The housing door can be pivotable or sliding between an open and a closed position.

[0026] The holding device is further configured to detachably couple the mobile transfer container to a connecting device assigned to the mobile transfer container, for positioning and holding it on the transfer device. The connecting device can, for example, be integrally formed with the mobile transfer container and / or a container receptacle, for instance, as a single piece. The container receptacle is designed to receive the mobile transfer container and can, for example, be formed with a mounting frame in which the mobile transfer container is either detachably or permanently held. The container receptacle, together with the mobile transfer container it holds, can be picked up and secured to the holding device.

[0027] A support or holding device may be arranged on the mobile transfer container and / or the container holder, which is designed to detachably receive and hold the associated coupling device. The support or holding device for the associated coupling device makes it possible to receive and hold the coupling device, particularly for storage. BOEHMERT & BOEHMERT

[0028] - 6 - if the associated coupling device is not (yet) connected to the coupling device. The support or holding device can be located adjacent to the mobile transfer container.

[0029] The associated coupling device is connected in particular via one or more flexible fluid lines to an interior of the mobile transfer container, which is designed in particular to transport the liquid spray additive, when the associated coupling device is connected to the coupling device for transferring the spray additive.

[0030] The support or holding device for the associated coupling device can be moved between the working and transport positions together with the holding device for the mobile transfer container. With the aid of the support or holding device, a fixed position can be provided for the associated coupling device relative to the holding device for the mobile transfer container and thus to the mobile transfer container that can be arranged therein. The support or holding device can be arranged laterally d when viewed from the front of the holding device for the mobile transfer container.

[0031] The associated coupling device can be clamped to the support or holding device.

[0032] The coupling device may include a guide device configured to interact with an associated guide device on the associated coupling device, such that the coupling device and the associated coupling device can be guided in a secure relative position during connection. The guide device and the associated guide device are configured to guide the coupling device and the associated coupling device during the formation of the fluid connection, thereby facilitating a safe and simple connection, particularly without jamming or snagging. This also facilitates easy disconnection of the connection between the coupling device and the associated coupling device. The guide device and / or the associated guide device may include guide elements that are separate from pipe connectors.

[0033] The assigned guide device can be formed with one or more guide elements which are configured, when connected, to form an assigned element assembly. BOEHMERT & BOEHMERT

[0034] - 7 - The guide device can be engaged. The one or more guide elements can be formed with a respective guide pin or rod. In one embodiment, the one or more guide elements are formed on the coupling device / associated coupling device and the associated element receptacles are formed on the associated coupling device / coupling device. Alternatively, it can be provided that one or more guide elements and one or more associated element receptacles protrude from both the coupling device and the associated coupling device.

[0035] The coupling device and the associated coupling unit can be configured to form at least two separate fluid connections when connected. Different fluids can be transferred separately between the mobile transfer container and the spray system via these separate fluid connections. For example, the liquid spray additive can be transferred on the one hand, and water on the other, for instance, for rinsing the mobile transfer container. The separate fluid connections are implemented using separate pipes and / or hoses, particularly flexible lines.

[0036] The coupling device and its associated coupling device can be configured to establish an electrical connection in addition to the fluid connection when connected. This electrical connection can be configured, for example, to transmit control signals and / or provide a power supply. For instance, the electrical connection can be configured to provide a power supply for electrically operated elements or components on the mobile transfer container, such as one or more valves. The coupling device and its associated coupling device can also be configured to establish the electrical connection simultaneously with the fluid connection when the coupling device and its associated coupling device are connected.To establish the electrical connection, one or more electrical connectors can be provided on the coupling device and the associated coupling device. In one embodiment, the one or more electrical connectors on the coupling device and the associated coupling device can each be arranged in a connection plane with one or more fluid connectors to form the one or more fluid connections. BOEHMERT & BOEHMERT.

[0037] - 8 -

[0038] The coupling device and I or the associated coupling device may have a gripping device that can be manually grasped by a user when connecting or disconnecting the detachable connection between the coupling device and the associated coupling device. In one embodiment, the gripping device may be arranged on a base plate of the coupling device and / or the associated coupling device, wherein the base plate has one or more openings in which a fluid connector for establishing the one or more fluid connections is received.

[0039] In one embodiment, the handle of the coupling device and / or the associated coupling device is integrally formed on the base plate. It may be possible to form the integrally formed handle by means of plate sections that are angled or bent with respect to the openings in the base plate.

[0040] The handle can be formed on one or both sides of the coupling device and / or the associated coupling device, for example on both sides of the base plate.

[0041] The handle of the coupling device and / or the associated coupling device may have a grip recess into which the user can grasp with one or more fingers.

[0042] The relocation device can be formed with a manual relocation mechanism that can be operated manually by a user to move the holding device between the working position and the transport position. In this way, the operating effort for the user is kept to a minimum.

[0043] The holding device can be arranged on a support arm of the transfer device, which can be moved into a first and a second support arm position to relocate the holding device. For example, the first and second support arm positions are configured as an extended / unfolded position and a retracted / folded position, respectively. When the transfer device is in the working position, the support arm can extend through the housing opening of the protective housing. In this case, the housing opening is clear of the housing door. In the transport position, the support arm can be completely enclosed within the protective housing, including the container receptacle located on the support arm. BOEHMERT & BOEHMERT

[0044] - 9 -

[0045] The support arm can be pivotable and / or slidable to move it into the first and second support arm positions. The support arm can be formed with support arm components that are slidable relative to each other to move it into the first and second support arm positions. For example, support arm components can be nested within each other in such a way that they are moved relative to each other to assume the first or second support arm position. It is also possible for support arm components to be pivotable relative to each other.

[0046] A locking device may be provided to secure the mobile transfer container to the holding device after it has been positioned there, particularly in a stationary position. This locking device secures the mobile transfer container to the holding device, for example, in a fixed position, thus preventing, for instance, the unintentional displacement of the mobile transport container from the holding device and further improving safety when handling the closed transfer system. The locking device may be configured to form a click, snap, and / or clamp connection for the mobile transfer container to the holding device. Such a locking connection may be manually releasable from the holding device, particularly without tools.

[0047] A transport holding device may be provided, connected to the frame and configured to allow the mobile transfer container to be detachably held separately from the holding device on the transfer device for transport. If the mobile transfer container is to be transported with the agricultural sprayer without the immediate intention of transferring the liquid cleaning agent additive into the spray system, the transport holding device, which is separate from the receiving device and the holding device on the transfer device, enables the safe transport of the mobile transfer container. The transport holding device may be configured to hold and secure the mobile transfer container in a fixed position on the agricultural sprayer, particularly relative to the spray system. The transport holding device may be permanently attached to the frame of the agricultural sprayer.

[0048] The transport holding device can be configured to allow the container holder to detachably accommodate the mobile transport container arranged therein. BOEHMERT & BOEHMERT

[0049] - 10 -

[0050] The transport holding device can have a protective roof or cover above a receptacle for the mobile transfer container, thus protecting the mobile transfer container, especially in rainy weather.

[0051] The transport holding device may, in addition to the receptacle for the mobile transfer container, have a separate holding receptacle or storage area for the associated coupling device, for example adjacent to and / or to the side of the receptacle for the mobile transfer container.

[0052] The transport holding device can be positioned laterally on the agricultural sprayer, for example, to the side of the spray tank. Alternatively, the transport holding device can also be positioned at the rear.

[0053] The transport holding device can be formed with a securing device designed to secure the mobile transfer container in the receptacle, thereby preventing, in particular, the unintentional release of the mobile transfer container from the receptacle on the transport holding device, for example in the event of vibrations during road travel of the agricultural spraying machine.

[0054] The coupling device and the associated coupling device can each have connecting elements configured to form a banjo connection. For example, the fluid connectors, which can be designed to be pluggable, can be configured to form the banjo connection. Such fluid connectors can be designed as dry-type or quick-connect coupling devices and, in one possible embodiment, are also referred to as "banjo dry poppet couplings".

[0055] In an alternative embodiment, regardless of the provision of the receiving device, an agricultural spraying machine for applying a spraying agent can be formed, comprising the following: a frame; a spraying system arranged on the frame and configured to receive a spraying agent in a tank and apply it by means of spraying; a coupling device formed on the spraying system side; and an associated coupling device formed on the transfer system side. The coupling device is connected to the spraying system via a fluid line and can be detachably coupled to the associated coupling device of a closed transfer system, which is a BOEHMERT & BOEHMERT

[0056] - 11 - mobile transfer container for providing a liquid spray additive that can be mixed with the spraying agent in the spraying system for application. The coupling device is further configured to form a fluid connection by coupling to the associated coupling device, through which the chemical spray additive can be supplied from the mobile transfer container to the spraying system. In connection with the coupling device and / or the associated coupling device, the configurations described in connection with the agricultural sprayer with the receiving device can be provided accordingly, but optionally also for an agricultural sprayer without the receiving device, which is formed by the transfer device and the holding device.

[0057] The mobile transfer container, which can be detached and held securely on the holding device, is, for example, a mobile transfer container for a closed transfer system according to the design in document WO 2023 / 194918 A1.

[0065] - 12 -

[0066] Fig. 6 shows a schematic perspective view of an arrangement for forming fluid connections with a coupling device and an associated coupling device connected thereto and

[0067] Fig. 7 shows a schematic perspective representation of the coupling device and the associated coupling device in the separated state.

[0068] Figures 1 to 3 show schematic representations of an arrangement in a section of an agricultural sprayer, particularly in a rear section. The agricultural sprayer is equipped with a spray system 1 on a frame 2 for applying a liquid spray, for example, a pesticide or fertilizer. For this purpose, the agricultural sprayer has a tank (not shown) for receiving the liquid spray, in particular water, and the spray system 1 for applying the spray. The spray system 1 can be of a conventional design, as is known for various configurations of agricultural sprayers.For example, the spray system 1 has in particular a pump device for generating the spray pressure as well as pipe and / or hose lines, valves and spray nozzles for applying the spraying agent, which are regularly arranged on one or more booms, which can be extended for spraying and retracted for transport.

[0069] It is regularly planned to add one or more liquid spray additives, such as chemical and / or biological additives, to the spray medium, especially water. For this purpose, it is necessary to supply the liquid spray additive to spray system 1 in a safe and efficient manner.

[0070] For this purpose, as shown in Fig. 1, a receiving device 3 is provided with a transfer device 4, which in the example shown is formed with a support arm 5, and a holding device 6 arranged on the transfer device 4, on which a mobile transfer container 7, which in the embodiment shown is portable, of a closed transfer system is arranged for holding. Such a closed transfer system for the safe transfer of liquid spray additives to a spraying system of an agricultural sprayer is disclosed, for example, in document WO 2023 / 194918 A1. BOEHMERT & BOEHMERT

[0071] - 13 -

[0072] The spray system 2 is connected to a coupling device 8, which in the example shown is configured with a first and a second fluid connector 8a, 8b, such that a liquid supplied via the coupling device 8 can be supplied to the spray system 2. Conversely, it can be provided that a liquid, for example water from the tank, can be dispensed from the spray system 1 via the coupling device 8 on the spray system side. This water can, for example, be used to rinse the mobile transfer container 7 after the liquid spray additive has been transferred from it to the spray system 1.

[0073] The mobile transfer container 7 is connected via flexible pipe or hose lines (not shown) to a coupling device 9 associated with the coupling device 8. The associated coupling device 9 forms a coupling device on the transfer system side and, in the example shown, is configured with two fluid connectors 9a, 9b, such that the coupling device 8 and the associated coupling device 9 can be connected to each other to form two fluid connections, in particular by push-fit connection, which is shown schematically in Fig. 2 by means of an arrow A (see also the explanations for Figs. 6 and 7 below).

[0074] Fig. 2 shows a schematic perspective detail of the arrangement from Fig. 1. The container holder 6 is positioned in a working position by means of the support arm 5, which allows the mobile transfer container 7 to be attached to the holding device 6. For this purpose, the support arm 5 is extended or unfolded such that the holding device 6, with the mobile transfer container 7 arranged therein, is in a distal position. The support arm 5 is formed with support arm components 5a, 5b, which can be at least partially inserted into one another, so that the support arm 5 can be lengthened or shortened by relative displacement of the support arm components 5a, 5b. This makes it possible to move the holding device 6 into a transport position, as shown in Fig. 3, when the mobile transfer container 7 has been removed from it.

[0075] When the holding device 6 is arranged in the working position according to Figures 1 and 2, the support arm 5 of the displacement device 4 extends through a housing opening 10 of a protective housing 11, which can be opened and closed by means of a housing door 12. In the illustrated embodiment, this door is pivotable between a closed position and the open position shown in Figures 1 to 3. BOEHMERT & BOEHMERT

[0076] - 14 -

[0077] The mobile transfer container 7 can be filled with the liquid spray additive via a closable container opening 13, particularly when the mobile transfer container 7 is not attached to the holding device 6. In the illustrated embodiment, the liquid spray additive enters a secondary tank 14 on the spray system side, which in this exemplary embodiment is at least partially enclosed in the protective housing 11.

[0078] The coupling device 9 associated with the transfer system is detachably arranged in a holder or receptacle 15 to the side of the holding device 6 and the mobile transfer container 7, as shown in Figs. 1 and 2.

[0079] In the example shown, the mobile transfer container 7 is arranged in an associated container receptacle 7a, which is formed with a frame or component. Handle elements 7b are provided on the container receptacle 7a, which can be used by an operator to grasp the mobile transfer container 7, for example, when attaching it to or detaching it from the holding device 6.

[0080] The container receptacle 7a and the holder or receptacle 15 for the associated coupling device 9 can be rigidly connected to each other. To establish the fluid connections, the associated coupling device 9 is manually removed from the holder or receptacle 15 by the user and connected to the coupling device 8 (see arrow A in Fig. 2).

[0081] The coupling device 9 associated with the transfer system is connected to the mobile transfer container 7 via flexible fluid lines 16a, 16b (see Fig. 2; omitted in Figs. 1 and 4 for the sake of simplicity) which enable the associated coupling device 9 to be moved to the coupling device 8 on the spray system side and coupled to the coupling device 8.

[0082] If the mobile and portable transfer container 7 is not required for feeding the liquid spray additive into the spray system 1, but still needs to be transported safely with the agricultural sprayer, the mobile transfer container 7 can be detachably arranged in a transport holding device 20 as shown in Fig. 4. This device has a receptacle 21 for the mobile and portable transfer container 7, for example, for inserting or suspending it, as well as a further receptacle 22 for the coupling device 9 associated with the transfer system. A protective or BOEHMERT & BOEHMERT

[0083] - 15 -

[0084] The cover roof 23 is provided to protect the mobile transfer container, especially from weather conditions, when the mobile transfer container is arranged in the transport holding device 20.

[0085] In the example shown, the mobile transfer container 7 remains in the container receptacle 7a, which, according to Fig. 4, is arranged together with the mobile transfer container ? on the transport holding device 20 for holding.

[0086] The transport holding device 20, which is shown in Fig. 5 free from the mobile transfer container 7, can, for example, be arranged laterally on the agricultural sprayer, for example, to the side of the tank (not shown) for the spraying agent. Alternatively, the transport holding device 20 can be arranged at the rear of the agricultural sprayer.

[0087] Figures 6 and 7 show schematic perspective views of the spray system-side coupling device 8 and the associated transfer system-side coupling device 9. In the illustration in Figure 6, the coupling device 8 and the associated coupling device 9 are connected to each other, such that two fluid connections are formed. In Figure 7, the coupling device 8 and the associated coupling device 9 are shown separately.

[0088] In addition to forming the fluid connection, the coupling devices 8, 9 further enabled the establishment of an electrical connection 30 by means of an electrical connector 31 on the coupling device 8 and an associated electrical connector 32 on the associated coupling device 9. The electrical connection 30 can be configured to transmit control signals and / or provide a power supply, for example for elements of the closed transfer system, such as valves on the mobile transfer container 7.

[0089] A guide device 40 is provided, which is designed to guide the coupling device 8 and the associated coupling device 9 during the connection between the two coupling devices 8 and 9, so that, in particular, misalignment or jamming does not occur. In the embodiment shown, the guide device 40 has guide receptacles 41 on the coupling device 8 and guide elements 42 on the associated coupling device 9. The guide elements 42 are supplied with BOEHMERT & BOEHMERT

[0090] - 16 -

[0091] Guide pins are formed which engage in the associated guide receptacles 41 when establishing the fluid connection and the electrical connection 30.

[0092] The associated coupling device 9 has a handle 50 (see especially Fig. 7) which the user can grasp by hand when connecting and disconnecting the coupling devices 8, 9. In the example shown, the handle 50 is integrally formed with a base plate 51 of the associated coupling device 9 and is formed with angled plate sections 52. These angled plate sections 52 provide a grip recess 53 into which one or more fingers can be inserted.

[0093] The base plate 51, which can be made of metal, for example, has openings or through-holes 54 in which fluid connectors 55 are arranged, which serve to form the fluid connections when the coupling device 8 and the associated coupling device 9 are detachably connected to each other (see Fig. 6).

[0094] In the example shown, the base plate 51 of the associated coupling device 9 is formed with a first partial base plate 51a and a second partial base plate 51b spaced apart from it. The partial base plates 51a and 51b are arranged parallel to each other and connected via the fluid connectors 55. The partial base plates 51a and 51b can optionally be connected via a connecting plate section 51c that is perpendicular to them, for example, integrally connected to it.

[0095] The fluid connectors 55 can be configured to form a banjo connection when the coupling device 8 and the associated coupling device 9 are connected together.

[0096] In this or other embodiments, the fluid connectors 55 and / or the electrical connectors 31, 32 may have a self-locking mechanism designed to secure the respective connection after the coupling device 8 and its associated coupling device 9 have been joined, such that they are secured against unintentional disconnection but can be released by the user if necessary. For example, a click, latch, snap, and / or clamp connection may be provided between the respective associated connectors of the coupling device 8 and the associated coupling device 9.

[0098] In the example shown, the electrical connector 31 and the associated electrical connector 32 are each arranged on a laterally molded plate section 56. The features disclosed in the preceding description, the claims, and the drawing can be important for the realization of the various embodiments, both individually and in any combination.
