Description

Technical Field

[0001] The present application relates to the field of nuclear magnetic resonance, and in particular to a wearable auxiliary device, a control method, a system and a storage medium for a wearable nuclear magnetic resonance instrument. Background Art

[0002] Nuclear magnetic resonance utilizes the characteristics of the spin motion of atomic nuclei. The human body is placed in a special external magnetic field, and the hydrogen nuclei in the human body are excited by radiofrequency pulses. This causes the hydrogen nuclei to resonate and absorb energy. After the radiofrequency pulse stops, the hydrogen nuclei emit electrical signals at a specific frequency and release the absorbed energy, which is recorded by a receiver outside the body and processed by an electronic computer to obtain an image. In the field of modern medicine, nuclear magnetic resonance examination has become one of the routine examinations, and more and more patients need to undergo nuclear magnetic resonance examination.

[0003] In the related art, the structure of the nuclear magnetic resonance examination bed is simple and integrated with the nuclear magnetic resonance main unit, which is inconvenient to use. Therefore, a wearable nuclear magnetic resonance instrument similar to a coat has emerged. By controlling the magnitude and polarity of the current passing through the gradient coil, the required gradient field can be generated and the spatial rotation effect of the gradient field can be achieved.

[0004] However, currently, the wearable nuclear magnetic resonance instrument needs to be worn by medical staff for patients. It is extremely inconvenient to wear and transfer for patients with limited mobility or those who have just undergone surgery, increasing the workload of medical staff, and there is still room for improvement. Summary of the Invention

[0005] In order to reduce the workload of medical staff in wearing a wearable nuclear magnetic resonance instrument for patients with limited mobility or those who have just undergone surgery, the present application provides a wearable auxiliary device, a control method, a system and a storage medium for a wearable nuclear magnetic resonance instrument.

[0006] In the first aspect, the present application provides a wearable auxiliary device for a wearable nuclear magnetic resonance instrument, adopting the following technical solution:

[0007] A wearable auxiliary device for a wearable nuclear magnetic resonance instrument is installed on a bed body, and includes at least two lifting components arranged on the bed body and slidably connected to the bed body, a driving component arranged on the lower side of the bed body to drive the lifting components to lift and lower, and a driving component arranged on the lifting plate to drive two opposite supporting plates to approach or separate from each other. At least two of the lifting components are symmetrically arranged on both sides of the bed body;

[0008] The lifting component includes at least one supporting plate arranged on the lower side of the bed body, a supporting plate integrally arranged at one end of the supporting plate away from the bed body and extending downward, and a cross plate integrally arranged at one end of the supporting plate away from the supporting plate. The cross plate extends from the supporting plate towards the direction close to the bed body;

[0009] The driving assembly includes at least two driving motors fixed to the lower side of the bed body, lifting lead screws fixedly corresponding to the output shafts of the driving motors one by one, and a lifting plate sleeved on at least two lifting lead screws and threadedly connected to the lifting lead screws. The lifting lead screws are arranged vertically upward. There is a fixing plate on the lower side of the bed body, and the driving motors are fixed to the fixing plate. The support plate synchronously lifts and lowers with the lifting plate.

[0010] By adopting the above technical solution, the driving assembly drives the two lifting assemblies to slide out from both sides of the bed body, and then the driving assembly drives the driving assembly and the lifting assemblies to rise until the lower side of the support plate is flush with the lower side of the bed body. The driving assembly drives the two lifting assemblies to approach each other, and the support plate is inserted between the human body and the bed body. The driving assembly drives the driving assembly and the lifting assemblies to rise to lift a patient with limited mobility or who has just undergone surgery from the bed body. Then, the wearable nuclear magnetic resonance instrument is laid flat on the bed body under the human body. After that, the driving assembly drives the driving assembly and the lifting assemblies to lower until the lower side of the support plate abuts against the upper side of the bed body. Then, the driving assembly drives the two lifting assemblies to move away from each other to place the human body on the wearable nuclear magnetic resonance instrument. Medical staff then connect the two sides of the wearable nuclear magnetic resonance instrument together to form a closed loop, and the wearing of the wearable nuclear magnetic resonance instrument can be completed, reducing the workload of medical staff in wearing the wearable nuclear magnetic resonance instrument for patients with limited mobility or who have just undergone surgery. One medical staff can complete the wearing of the wearable nuclear magnetic resonance instrument for patients with limited mobility or who have just undergone surgery.

[0011] Optionally, the driving assembly includes at least one screw member rotatably connected to the lower side of the lifting plate and arranged horizontally, a driving motor fixed to the lifting plate to drive the screw member to rotate, and at least one guiding column fixed to the lower side of the lifting plate. The cross plate is sleeved on the screw member and threadedly connected to the screw member, and the cross plate is sleeved on the guiding column and slidably connected to the guiding column.

[0012] By adopting the above technical solution, the driving motor drives the screw member to rotate, and the screw member drives the cross plate to slide along the axial direction of the screw member through the threaded connection between the screw member and the cross plate, so as to realize the mutual approach or mutual separation of the two lifting assemblies.

[0013] Optionally, the screw member includes a stepped shaft portion rotatably connected to the lower side of the lifting plate and threaded portions symmetrically arranged at both ends of the stepped shaft portion, and the number of driving motors is one.

[0014] By adopting the above technical solution, one driving motor cooperating with one screw member can drive the two lifting assemblies to approach or separate from each other, reducing the use cost and realizing the synchronous control of the two lifting assemblies at the same time.

[0015] Optionally, the lifting assembly further includes an extension plate pivotally connected to one end of the support plate away from the support board, and the extension plate can be reversibly stored on the upper side of the support plate;

[0016] When the lifting components lift the human body, the ends of the extension plates of the two lifting components away from the supporting plates abut against each other.

[0017] By adopting the above technical solution, the setting of the extension plate makes there be no gap between the supporting plates when the lifting components lift the human body, thereby improving the comfort when the lifting components lift the human body and making it difficult for the human body to be injured when being lifted.

[0018] Optionally, a magnetic block is further fixed on the extension plate. When the extension plate is turned over and stored on the upper side of the supporting plate, the magnetic block is located on the side of the extension plate away from the supporting plate, and magnetic strips that cooperate with and attract the magnetic block are provided on both sides of the bed body.

[0019] By adopting the above technical solution, when the supporting plate moves from the lower side of the bed body to the upper side of the bed body, the extension plate can be turned over to be flush with the supporting plate under the attraction of the magnetic strip and the magnetic block, realizing the automatic turning of the extension plate and reducing human intervention.

[0020] Optionally, at least one bull's eye is fixed on the lower side of the supporting plate.

[0021] By adopting the above technical solution, the setting of the bull's eye reduces the wear between the supporting plate and the wearable nuclear magnetic resonance instrument, and makes it difficult for the wearable nuclear magnetic resonance instrument to be scratched by the supporting plate.

[0022] In a second aspect, the present application provides a control method for a wearable nuclear magnetic resonance instrument wearing assistance device, adopting the following technical solution:

[0023] A control method for a wearable nuclear magnetic resonance instrument wearing assistance device includes:

[0024] Judging whether a trigger signal is received;

[0025] If so, start and obtain the lying posture information of the human body on the bed body, otherwise, do not start;

[0026] Judging whether the lying posture information of the human body is correct;

[0027] If so, control the lifting components to move to a preset height, otherwise, give an alarm and return to obtain the lying posture information of the human body on the bed body;

[0028] Judging whether a receiving module preset on the extension plate receives a signal emitted by a transmitting module preset on the supporting plate;

[0029] If so, give an alarm, otherwise control the two lifting components to be inserted between the human body and the bed body, and then drag the human body away from the bed body.

[0030] By adopting the above technical solution, after receiving the trigger signal, the lying posture of the human body on the bed is obtained, and it is judged whether the lying posture of the human body is correct. If it is correct, the driving component drives the two lifting components to slide out from both sides of the bed, and then the driving component drives the driving component and the lifting components to rise until the lower side of the pallet is flush with the lower side of the bed. Then it is judged whether the receiving module preset on the extension board receives the signal emitted by the transmitting module preset on the pallet. If the receiving module does not receive the signal emitted by the transmitting module, the driving component drives the two lifting components to approach each other, the pallet is inserted between the human body and the bed, and the driving component drives the driving component and the lifting components to rise to lift the patient with inconvenient mobility or who has just had surgery from the bed. After that, the medical staff can lay the wearable nuclear magnetic resonance instrument flat on the bed under the human body without the medical staff lifting the patient, reducing the workload of the medical staff in wearing the wearable nuclear magnetic resonance instrument for the patient with inconvenient mobility or who has just had surgery. One medical staff can complete the task of wearing the wearable nuclear magnetic resonance instrument for the patient with inconvenient mobility or who has just had surgery.

[0031] Optionally, the method for judging whether the lying posture information of the human body is correct is as follows:

[0032] A number of pressure sensors are evenly arranged on the upper side of the bed;

[0033] Obtain the pressure values of the pressure sensors on the upper side of the bed;

[0034] Obtain the triggering quantity of the pressure sensors according to the pressure values of the pressure sensors on the upper side of the bed and the reference pressure value;

[0035] Judge whether the triggering quantity of the pressure sensors is greater than the triggering reference value;

[0036] If so, the lying posture of the human body is correct, otherwise, an alarm is given.

[0037] By adopting the above technical solution, it is possible to accurately judge whether the lying posture information of the patient is correct, reducing the workload of the medical staff.

[0038] In the third aspect, the present application provides a control system for a wearable nuclear magnetic resonance instrument wearing assistance device, adopting the following technical solution:

[0039] A control system for a wearable nuclear magnetic resonance instrument wearing assistance device includes a memory and a processor, and a computer program capable of being loaded and executed by the processor as described in any one of the above methods is stored on the memory.

[0040] In the fourth aspect, the present application provides a computer-readable storage medium, adopting the following technical solution:

[0041] A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor as described in any one of the above methods.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] It reduces the workload of medical staff in dressing a wearable nuclear magnetic resonance instrument for patients with limited mobility or those who have just had surgery. Description of the Drawings

Detailed Description of the Embodiment

[0054] The following will further describe the present application in detail in combination with the appended Figures 1-9 drawings.

[0055] An embodiment of the present application discloses a wearing assistance device for a wearable nuclear magnetic resonance instrument. Refer to Figure 1 , the wearing assistance device for the wearable nuclear magnetic resonance instrument includes a lifting component 2 and a driving component 3. The lifting component 2 and the driving component 3 are both installed on the lower side of the bed body 1. The number of the lifting components 2 is two, and the two lifting components 2 are symmetrically arranged on both sides of the bed body 1.

[0056] Refer to Figure 1 , 2 , there are two groups of legs 12 on the lower side of the bed body 1. The two groups of legs 12 are arranged at intervals along the length direction of the bed body 1. A fixing plate 11 is fixed between the two groups of legs 12. The driving component 3 is installed on the fixing plate 11. The driving component 3 is used to drive the lifting component 2 to lift and lower. The driving component 3 includes a driving motor 31, a lifting lead screw 32 and a lifting plate 33; the number of the driving motors 31 is two, and the two driving motors 31 are both installed on the fixing plate 11. The two driving motors 31 are arranged at intervals along the length direction of the fixing plate 11. The output shaft of the driving motor 31 penetrates through the fixing plate 11 and is arranged vertically upward; the lifting lead screw 32 corresponds to the driving motor 31 one by one. The lifting lead screw 32 is arranged vertically. The lifting lead screw 32 is fixed to the output shaft of the driving motor 31 to rotate under the drive of the driving motor 31; the lifting plate 33 is parallel to the fixing plate 11. The lifting plate 33 is sleeved on the two lifting lead screws 32 and is threadedly connected to the lifting lead screws 32.

[0057] Refer to Figure 2 , 3 , the lifting component 2 includes a support plate 21 and a support board 22. The support plate 21 is arranged on the upper side of the bed body 1. The support plate 21 is arranged horizontally. The support board 22 is integrally arranged at one end of the support plate 21 away from the lifting plate 33. The support board 22 is arranged vertically. The lower end of the support board 22 can be fixedly connected to the lifting plate 33 or can be slidably connected to the lifting plate 33 in the horizontal direction. When the lower end of the support board 22 is fixedly connected to the lifting plate 33, the support plate 21 can only be arranged on the upper side of the bed body 1 and it is difficult to be received under the bed body 1.

[0058] In order to enable the lifting component 2 to be received under the bed body 1 when not in use, the lifting component 2 further includes a cross plate 23. The cross plate 23 is fixed to the lower end of the support board 22. The cross plate 23 is arranged horizontally. The cross plate 23 extends towards the direction close to the lifting plate 33; in order to enable the lifting component 2 to be received under the bed body 1 when not in use, the wearing assistance device for the wearable nuclear magnetic resonance instrument further includes a driving component 4. The driving component 4 is used to drive the two lifting components 2 to approach each other or move away from each other.

[0059] Refer to Figure 3 , 4, the driving assembly 4 includes a lead screw member 41, a driving motor 42 and a guide post 43; the lead screw member 41 includes a stepped shaft portion 411 and two threaded portions 412, the two threaded portions 412 are symmetrically arranged at both ends of the stepped shaft portion 411, and the thread directions of the two threaded portions 412 are set in opposite directions. The lower side of the lifting plate 33 has two parallel second vertical plates 332. The stepped shaft portion 411 is rotatably connected to the two second vertical plates 332 through bearings, and the stepped shaft portion 411 does not axially slide relative to the second vertical plates 332. One end of the cross plate 23 away from the support plate 22 has a connecting plate 231, the connecting plate 231 is sleeved on the threaded portion 412 and is threadedly connected to the threaded portion 412; the number of driving motors 42 is one, the driving motor 42 is fixed on the lifting plate 33, and the driving motor 42 is used to drive the lead screw member 41 to rotate. The driving motor 42 can drive the lead screw member 41 to rotate through a worm and worm gear drive, or can drive the lead screw member 41 to rotate through a bevel gear drive. In this embodiment, the bevel gear drive is taken as an example for introduction; the number of guide posts 43 is at least one. The lower side of the lifting plate 33 has first vertical plates 331 corresponding to the guide posts 43 one by one. The guide posts 43 are fixed on the first vertical plates 331. The guide posts 43 are parallel to the lead screw member 41. The guide posts 43 pass through the connecting plate 231 and are slidably connected to the connecting plate 231 to guide the connecting plate 231 to slide.

[0060] Referring to Figure 3 , 5 , the lifting assembly 2 further includes an extension plate 24. The extension plate 24 is pivotally connected to one end of the tray 21 away from the support plate 22 through a hinge, and the extension plate 24 can be received and abutted on the upper side of the tray 21 when not in use; taking the extension plate 24 being received and abutted on the upper side of the tray 21 as an example, a magnet 241 is embedded and installed on the upper side of the extension plate 24, and magnetic strips 13 are provided on both sides of the bed body 1. The side of the magnet 241 away from the extension plate 24 attracts the side of the magnetic strip 13 away from the bed body 1.

[0061] Referring to Figure 5 , the driving assembly 4 drives the two lifting assemblies 2 to move away from each other and slide out from under the bed body 1. After the tray 21 slides out from under the bed body 1, the driving assembly 3 drives the driving assembly 4 and the lifting assembly 2 to rise together. The extension plate 24 flips towards the direction close to the bed body 1 under the action of the mutual attraction between the magnet 241 and the magnetic strip 13. When the lower side of the tray 21 is flush with the upper side of the bed body 1, the side of the extension plate 24 close to the magnet 241 flips and abuts against the upper side of the bed body 1.

[0062] Referring to Figure 6, the driving component 4 drives the two lifting components 2 to approach each other until the two extension plates 24 abut against each other, that is, the support plate 21 and the extension plate 24 are inserted between the human body bed 1. Then, the driving component 3 drives the driving component 4 and the lifting component 2 to rise together to lift the human body on the upper side of the bed 1, and then lays the wearable nuclear magnetic resonance instrument flat on the bed 1 directly below the human body.

[0063] Referring to Figure 7 , the driving component 3 drives the driving component 4 and the lifting component 2 to descend to place the human body on the wearable nuclear magnetic resonance instrument. Then, the driving component 3 drives the two lifting components 2 to move away from each other. In order to reduce the friction between the support plate 21 and the extension plate 24 and the wearable nuclear magnetic resonance instrument, bull's eyes are fixedly installed on the lower sides of the support plate 21 and the extension plate 24. When the end of the support plate 21 close to the bed 1 is flush with the side surface of the bed 1, the driving component 3 drives the driving component 4 and the lifting component 2 to descend. The extension plate 24 flips in the direction close to the support plate 21 under the limiting action of the bed 1 until the gap between the upper side of the support plate 21 and the lower side of the bed 1 can accommodate the extension plate 24. The driving component 4 drives the two lifting components 2 to approach each other and be stored under the bed 1.

[0064] The embodiment of the present application also discloses a control method for a wearable assistance device of a wearable nuclear magnetic resonance instrument, including: determining whether a trigger signal is received; if so, starting and obtaining the lying posture information of the human body on the bed, otherwise, not starting; determining whether the lying posture information of the human body is correct; if so, controlling the lifting component to move to a preset height, otherwise, returning to obtain the lying posture information of the human body on the bed; determining whether a preset receiving module on the extension plate receives a signal emitted by a preset transmitting module on the support plate; if so, giving an alarm, otherwise, controlling the two lifting components to be inserted between the human body and the bed, and then dragging the human body away from the bed.

[0065] In the embodiment of the present invention, after receiving the trigger signal, the lying posture of the human body on the bed is obtained, and it is determined whether the lying posture of the human body is correct. If it is correct, the driving component drives the two lifting components to slide out from both sides of the bed, and then the driving component drives the driving component and the lifting component to rise until the lower side of the support plate is flush with the lower side of the bed. Then, it is determined whether a preset receiving module on the extension plate receives a signal emitted by a preset transmitting module on the support plate. If the receiving module does not receive the signal emitted by the transmitting module, the driving component drives the two lifting components to approach each other, the support plate is inserted between the human body and the bed, and the driving component drives the driving component and the lifting component to rise to lift a patient with inconvenient movement or who has just undergone surgery from the bed. After that, medical staff can lay the wearable nuclear magnetic resonance instrument flat on the bed under the human body, without the need for medical staff to lift the patient, reducing the workload of medical staff in wearing the wearable nuclear magnetic resonance instrument for patients with inconvenient movement or who have just undergone surgery. One medical staff can complete wearing the wearable nuclear magnetic resonance instrument for patients with inconvenient movement or who have just undergone surgery.

[0066] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0067] In addition, the term "and / or" in this text merely describes the associated relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally represents an "or" relationship between the associated objects before and after, unless otherwise specified.

[0068] A control method for a wearable auxiliary device of a wearable nuclear magnetic resonance instrument is mainly described in the following process.

[0069] As Figure 8 shown:

[0070] Step 1100: Determine whether a trigger signal is received.

[0071] Among them, the trigger signal can be triggered by manually pressing a button, or can be triggered by means of voice, gesture, etc.

[0072] Step 1200: If so, start and obtain the lying posture information of the human body on the bed; otherwise, do not start.

[0073] Among them, receiving the trigger signal indicates that the medical staff is going to wear the wearable nuclear magnetic resonance instrument on the patient, so start and further obtain the lying posture information of the human body on the bed to facilitate accurate control of the wearable auxiliary device and reduce misoperations and repeated operations; if the trigger signal is not received, do not start.

[0074] Step 1300: Determine whether the lying posture information of the human body is correct.

[0075] Step 1400: If so, control the lifting component to move to a preset height; otherwise, give an alarm and return to obtain the lying posture information of the human body on the bed.

[0076] Among them, if the lying posture of the human body is correct, the driving component drives the two lifting components to slide out from both sides of the bed, and then the driving component drives the driving component and the lifting component to rise until the lower side of the tray is flush with the lower side of the bed; otherwise, the medical staff is reminded to calibrate the lying posture of the patient through an alarm, and the lying posture information of the human body on the bed is obtained again; the alarm can be one or more of a light alarm and a voice alarm.

[0077] Step 1500: Determine whether the preset receiving module on the extension plate receives the signal emitted by the preset transmitting module on the pallet.

[0078] Among them, taking the example that the extension plate is reversibly stored on the upper side of the pallet, at this time, a transmitting module is installed on the side of the extension plate close to the pallet, and a receiving module is installed on the side of the pallet close to the extension plate. If the receiving module receives the signal emitted by the transmitting module, it indicates that the extension plate is received and stored on the upper side of the pallet. Otherwise, it indicates that the side of the extension plate with the transmitting module installed is flush with the upper side of the pallet; the alarm can be one or more of a light alarm and a voice alarm.

[0079] Step 1600: If so, give an alarm. Otherwise, control the two lifting components to insert between the human body and the bed body, and then drag the human body away from the bed body.

[0080] Among them, if the receiving module receives the signal emitted by the transmitting module, it indicates that the extension plate is received and stored on the upper side of the pallet. Then, an alarm is used to remind the medical staff to manually flip the extension plate so that the side of the extension plate with the transmitting module installed is flush with the upper side of the pallet. Otherwise, it indicates that the side of the extension plate with the transmitting module installed is flush with the upper side of the pallet. Control the driving component to drive the two lifting components to approach each other, insert the pallet and the extension plate between the human body and the bed body, and the driving component drives the driving component and the lifting component to separate the human body from the bed body.

[0081] As Figure 9 shown, the method for judging whether the human lying posture information is correct is as follows:

[0082] Step 1311: Obtain the pressure value of the pressure sensor on the upper side of the bed body.

[0083] Among them, several pressure sensors are evenly arranged on the bed body. When an object is placed on the upper side of the pressure sensor, the pressure sensor will output a pressure value.

[0084] Step 1312: Obtain the triggering quantity of the pressure sensor according to the pressure value of the pressure sensor on the upper side of the bed body and the reference pressure value.

[0085] Among them, the number of pressure sensors whose pressure value is greater than the reference pressure value is the triggering quantity of the pressure sensor.

[0086] Step 1313: Determine whether the triggering quantity of the pressure sensor is greater than the triggering reference value.

[0087] Among them, the trigger reference value is directly proportional to the height and weight of the human body. The trigger reference values corresponding one-to-one to the height and weight of the human body are stored in a preset database. An RFID reader for reading the RFID tag worn on the patient is provided on the bed body. The RFID tag stores relevant information of the patient, including the height and weight of the patient. After the RFID reader reads the height and weight of the patient in the RFID tag, it retrieves from the database the trigger reference value corresponding one-to-one to the height and weight of the human body.

[0088] Step 1314: If so, the lying posture of the human body is correct; otherwise, an alarm is given.

[0089] Among them, if the trigger quantity of the pressure sensor is greater than the trigger reference value, it indicates that the lying posture of the human body is correct; otherwise, it indicates that the lying posture of the human body is incorrect. The medical staff is reminded to adjust the lying posture of the patient by means of an alarm. The alarm can be one or more of a light alarm and a voice alarm.

[0090] The embodiment of the present application also discloses a control system for a wearable auxiliary device of a nuclear magnetic resonance instrument, including a memory and a processor. A computer program capable of being loaded and executed by the processor as in Figure 8 and Figure 9 any one of the methods in the process is stored on the memory.

[0091] The embodiment of the present application also discloses a computer-readable storage medium, storing a computer program capable of being loaded and executed by the processor as in Figure 8 and Figure 9 any one of the methods in the process.

[0092] The computer-readable storage medium includes, for example: various media such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc that can store program codes.

[0093] Those skilled in the art can clearly understand that, for the convenience and simplicity of description, only the above division of each functional module is used for illustration. In practical applications, the above functions can be allocated to different functional modules according to needs, that is, the internal structure of the device is divided into different functional modules to complete all or part of the functions described above. The specific working processes of the systems, devices, and units described above can refer to the corresponding processes in the foregoing method embodiments and will not be repeated here.

[0094] In several embodiments provided in the present application, it should be understood that the disclosed systems, devices, and methods can be implemented in other ways. For example, the device embodiments described above are merely illustrative. For example, the division of the modules or units is only a logical function division. In actual implementation, there may be other division methods. For example, multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the displayed or discussed couplings or direct couplings or communication connections between each other can be through some interfaces.
