DETAILED DESCRIPTION

[0042] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0043] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0044] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0045] In one embodiment, a detection bed of an X-ray imaging system is provided. The detection bed is used to carry an object to be detected who is lying flat, lying on his side, or in other postures. A flat-panel detector can be installed inside the detection bed or on the side of the detection bed to realize X-ray shooting of the object to be detected on the carrying platform, generate X-ray data, and generate detection images to determine the lesions of the object to be detected.

[0046] The test bed has an electric rise or fall function, and multiple pedals are installed at the lower end of the test bed. The doctor can control the electric rise or electric fall of the test bed by stepping on the pedals, which is convenient and practical. The test bed can also have a floating function, and the pedals can lock and unlock the floating.

[0047] The multiple pedals of the inspection bed are installed uniformly, and the multiple pedals are installed on the same rotating shaft. Compared with the multiple pedals installed on different rotating shafts, the number of parts can be reduced, the installation is easy, and the assembly efficiency can be improved. The same rotating shaft can also play a natural leveling role. Without aligning multiple rotating shafts, it is easy to align multiple pedals in a straight line, and then multiple pedals are located at the same height position, which can easily ensure that the upper surfaces of multiple pedals are flush and have a good appearance.

[0048] Please refer to Figures 1 to 7 The testing bed of this embodiment mainly includes a bearing platform 1, a supporting device 2 and a pedal assembly 3. The bearing platform 1 is installed at the upper end of the supporting device 2, and the pedal assembly 3 is installed at the lower end of the supporting device 2. The pedal assembly 3 is located on the side of the standing doctor to facilitate the doctor to step on the pedal assembly 3.

[0049] The carrying platform 1 is a flat plate structure, the lower surface of the carrying platform 1 is connected to the supporting device 2, and the upper surface of the carrying platform 1 is used to carry the object to be detected. The middle part of the carrying platform 1 is a foam material structure that can penetrate X-rays, and the surrounding of the carrying platform 1 is a metal material structure that enhances the structural strength.

[0050] The support device 2 includes a support assembly 21 and a lifting drive assembly 22. The support assembly 21 can be a scissor-type cross structure. The load-bearing platform 1 is installed on the upper end of the support assembly 21. The support assembly 21 can move up and down to drive the load-bearing platform 1 to rise and fall. The lifting drive assembly 22 can be a driving structure such as an air pipe. The lifting drive assembly 22 is connected to the support assembly 21. The lifting drive assembly 22 is used to electrically control the support assembly 21 to drive the load-bearing platform 1 to rise and fall. The lifting drive assembly 22 can also be used to control the load-bearing platform 1 to stop at a desired height position.

[0051] The support device 2 may further include a base 23 and a panel 24. The base 23 is used to be installed on the ground. The support assembly 21 and the lifting drive assembly 22 may be installed on the base 23. The base 23 may also be a part of the support assembly 21. The panel 24 is an annular structure. The panel 24 wraps around the support assembly 21 and the lifting drive assembly 22 on the base 23. The panel 24 may include a plurality of sub-panels that are nested and can rise or fall. The sub-panel at the top is connected to the support assembly 21, and the sub-panel at the bottom is connected to the base 23. The plurality of sub-panels may rise or fall synchronously with the rise or fall of the support assembly 21. The panel 24 may wrap around the support assembly 21 and the lifting drive assembly 22, and may provide physical isolation protection for the support assembly 21 and the lifting drive assembly 22, and may also be more beautiful.

[0052] In other embodiments, the support device 2 may not include the enclosure 24 , and the support assembly 21 and the lifting drive assembly 22 are directly exposed to simplify the structure of the support device 2 .

[0053] In this embodiment, the carrying platform 1 can also be installed on the supporting device 2 in a floating manner relative to the supporting device 2, and the carrying platform 1 can move in the horizontal plane along the left-right direction and the front-back direction. The flat floating of the carrying platform 1 meets more shooting requirements of the detected object.

[0054] The support device 2 further includes a floating locking assembly 25, which can be an electromagnetic locking structure such as an electromagnet. The floating locking assembly 25 is installed at the upper end of the support assembly 1 and close to the load-bearing platform 1. The lower surface of the load-bearing platform 1 is provided with a metal structure corresponding to the floating locking assembly 25 and can be fixed by electromagnetic adsorption. The floating locking assembly 25 can lock and unlock the plane floating of the load-bearing platform 1. When the floating locking assembly 25 locks the plane floating of the load-bearing platform 1, the load-bearing platform 1 is adsorbed by the floating locking assembly 25, and the load-bearing platform 1 cannot float and move in the plane; when the floating locking assembly 25 unlocks the plane floating of the load-bearing platform 1, the load-bearing platform 1 is not adsorbed by the floating locking assembly 25, and the load-bearing platform 1 can float and move in the plane.

[0055] The floating locking assembly 25 may include two groups, one group of floating locking assemblies 25 is used to lock and unlock the left-right direction movement of the load-bearing platform 1, and the other group of floating locking assemblies 25 is used to lock and unlock the front-back direction movement of the load-bearing platform 1. The two groups of floating locking assemblies 25 are independent of each other and can be controlled independently. The two groups of floating locking assemblies 25 can also be set to be linked control, which is equivalent to setting one group of floating locking assemblies 25, and can realize simultaneous locking and unlocking of the front-back direction and left-right direction movement of the load-bearing platform 1.

[0056] In other embodiments, the floating locking assembly 25 may also be other structures, for example, the floating locking assembly 25 is a pin structure that can be electrically telescopically moved, and the carrying platform 1 is provided with a corresponding locking hole; when the pin moves to be inserted into the locking hole, the plane floating of the carrying platform 1 is locked; when the pin moves to be separated from the locking hole, the plane floating of the carrying platform 1 is unlocked. That is, the floating locking assembly 25 adopts a physical barrier structure, and can also achieve the locking and unlocking of the plane floating of the carrying platform 1.

[0057] In this embodiment, the pedal assembly 3 is installed at the lower end of the support device 2, and the pedal assembly 3 is located at the front side of the test bed, that is, the side where the doctor stands and uses. The pedal assembly 3 is fixed together with the support device 2 to improve the integrity of the test bed.

[0058] In other embodiments, the pedal assembly 3 may also be installed independently relative to the supporting device 2. The pedal assembly 3 is configured as a movable structure, and the pedal assembly 3 is fixed at different positions to meet the usage requirements of different doctors.

[0059] In this embodiment, the base 23 is provided with a mounting groove 231, and the pedal assembly 3 is installed in the mounting groove 231 of the base 23. The pedal assembly 3 is installed in a hidden manner, which can prevent the doctor from accidentally stepping on the pedal assembly 3 when walking. The pedal assembly 3 and the base 23 can use the same material and color surface, so that the pedal assembly 3 and the base 23 can be integrated into a structure, which is more simple and beautiful. The pedal assembly 3 can also be directly installed on the base 23, or the pedal assembly 3 and the base 23 can be installed in parallel, which can also achieve the installation and fixation of the pedal assembly 3.

[0060] The pedal assembly 3 mainly includes a mounting seat 31, a rotating shaft 32 and a plurality of pedals 33. The mounting seat 31 can be fixedly connected to the base 23 by means of screws, welding, clamping, etc.

[0061] The mounting seat 31 has a mounting cavity, the upper end and the front end of the mounting cavity are open structures, and the rotating shaft 32 and the plurality of pedals 33 are mounted in the mounting cavity of the mounting seat 31. The mounting seat 31 may include a bottom plate 311, a side plate 312 and a back plate 313. The bottom plate 311 may be mounted horizontally on the ground. The bottom plate 311 is a rectangular structure. The side plates 312 have two sides, and the two side plates 312 are respectively vertically mounted on the two sides of the short side of the bottom plate 311. The back plate 313 is vertically mounted on the rear end of the long side of the bottom plate 311. The left and right ends of the back plate 313 are respectively fixedly connected to the side plates 312. The bottom plate 311, the side plates 312 and the back plate 313 may be fixedly connected to each other by screws, welding, clamping, etc. to enclose the mounting cavity of the open structure. The side plates 312 and the back plate 313 are fixedly connected to the base 23 by screws, welding, clamping, etc.

[0062] The mounting seat 31 may be a sheet metal structure, and the bottom plate 311, the side plate 312 and the back plate 313 are all sheet metal parts. The mounting seat 31 made of sheet metal is easy to assemble and fix. The mounting seat 31 may also be a structural part such as a machined part or a casting, and the mounting seat 31 may also be set as an integrated structure.

[0063] The rotating shaft 32 is fixedly installed in the installation cavity of the mounting seat 31. The two ends of the rotating shaft 32 can be fixedly connected to the side plates 312 on the left and right sides of the mounting seat 31, respectively. The rotating shaft 32 is suspended relative to the bottom plate 311. The end of the rotating shaft 32 can pass through the side plate 312 and be located outside the installation cavity. The end of the rotating shaft 32 exposed from the installation cavity can be fixed to the side plate 312 by a locking member 321. The locking member 321 can be a locking structure such as a bolt, a pin, or a nut. The locking member 321 is used to limit the free end of the rotating shaft 32 that rotates relative to the mounting seat 31, that is, the rotating shaft 32 cannot rotate relative to the mounting seat 31. Setting the fixed position of the rotating shaft 32 outside the installation cavity can avoid the interference of the fixed installation structure of the rotating shaft 32 on the pedal 33, and improve the compactness of the structural layout in the installation cavity of the mounting seat 31. The rotating shaft 32 can also be directly fixed to the side plate 312 by welding.

[0064] Multiple pedals 33 are installed in the mounting cavity of the mounting seat 31, and multiple pedals 33 are installed on the same rotating shaft 32. The pedal 33 can be a sheet metal part, or a processed part or a casting part; the pedal 33 can be an aluminum plate, such as an aluminum sheet metal part, and aluminum has the advantages of corrosion resistance and light weight. Of course, the pedal 33 can also be made of other materials, such as aluminum alloy. The upper surface of the pedal 33 can be set to a curved surface structure to facilitate the doctor's footsteps.

[0065] In this embodiment, four pedals 33 are installed on the rotating shaft 32. In order to better distinguish the four pedals 33, the four pedals 33 are positioned as a first pedal 331, a second pedal 332, a third pedal 333 and a fourth pedal 334. The first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are installed side by side on the rotating shaft 32 in sequence. The first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 can rotate independently relative to the rotating shaft 32, that is, the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 can rotate respectively to trigger corresponding controls without affecting other pedals.

[0066] The first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 have the same structure. The lower ends of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are all provided with mounting holes, and the rotating shaft 32 is rotatably connected to the mounting holes of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334.

[0067] In this embodiment, the upper end of the back plate 313 is provided with a flipped folding portion, and the upper surface of the folding portion is a positioning surface 3131. The positioning surface 3131 is horizontally arranged and parallel to the rotating shaft 32. The positioning surface 3131 is located on the rotation path of the ends of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 on the same side. In the default state when the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are not stepped on, the ends of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 on the same side are all in contact with the positioning surface 3131, and the positioning surface 3131 can play a role in positioning and limiting. In the default state, the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 can be positioned by the positioning surface 3131 to achieve that the upper surfaces of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are flush, which is more beautiful. The upper surfaces of the multiple pedals 33 are flush, which means that if the upper surface of the pedal 33 is a plane or a curved surface, the upper surfaces of the multiple pedals 33 are in the same plane or the same curved surface; if the upper surface of the pedal 33 includes a combination of multiple planes or curved surfaces, the multiple planes or curved surfaces of the upper surfaces of the multiple pedals 33 are respectively located in the same plane or curved surface. In other words, when viewed from the left and right direction, the upper surfaces of the multiple pedals 33 overlap on the lines on the side of the upper surface.

[0068] Among them, the first pedal 331 is used to lock and unlock the left-right movement of the carrying platform 1, the second pedal 332 is used to control the upward movement of the carrying platform 1, the third pedal 333 is used to control the downward movement of the carrying platform 1, and the fourth pedal 334 is used to lock and unlock the front-back movement of the carrying platform 1. In this way, the first pedal 331 and the fourth pedal 334 can respectively lock and unlock the left-right and front-back movements of the carrying platform 1. The upper surfaces of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 can be respectively provided with corresponding marks to facilitate the doctor's selection and use.

[0069] In other embodiments, the back plate 313 may be provided with multiple folded edges to form multiple positioning surfaces 3131. The multiple positioning surfaces 3131 are located in the same plane. Each pedal 33 corresponds to a positioning surface 3131. The multiple pedals 33 may also be positioned in different planes.

[0070] In other embodiments, the functions of the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 can be interchanged. For example, the first pedal 331 and the second pedal 332 are respectively used to control the rise and fall of the supporting platform 1, and the third pedal 333 and the fourth pedal 334 are respectively used to control the locking and unlocking of the plane floating of the supporting platform 1.

[0071] In other embodiments, the first pedal 331 can be used to lock the left-right and front-back movements of the carrying platform 1, and the fourth pedal 334 can be used to unlock the left-right and front-back movements of the carrying platform 1. In this way, the left-right and front-back movements of the carrying platform 1 can be locked and unlocked simultaneously.

[0072] In other embodiments, three pedals 33 may be provided, and the functions of the first pedal 331 and the fourth pedal 334 may be combined into one pedal 33, so that the simultaneous locking and unlocking of the left-right and front-back movements of the supporting platform 1 may be achieved.

[0073] In this embodiment, the pedal assembly further includes a reset member 34, which may be a spring with elastic restoring force, for example, a compression spring. The compression spring is vertically mounted on the bottom plate 311, and is located away from the back plate 313, that is, the compression spring and the positioning surface 3131 are located on both sides of the rotating shaft 32, and the upper end of the compression spring is connected to the lower surface of the pedal 33 at one end of the pedal 33 away from the positioning surface 3131, and the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are respectively connected to one or two compression springs, or more compression springs.

[0074] In the default state when not stepped on, the compression spring provides an upward elastic force to the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 respectively, and the elastic force drives the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 to rotate until they abut against the positioning surface 3131, and the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 are in a flush position.

[0075] In the triggered state of stepping, the stepped pedal 33 among the first pedal 331 , the second pedal 332 , the third pedal 333 and the fourth pedal 334 rotates, one end of the pedal 33 presses down the compression spring, and the other end is separated from the positioning surface 3131 .

[0076] In other embodiments, the reset member 34 may also be a spring in other forms, for example, the reset member 34 is a tension spring, which is vertically mounted on the bottom plate 311, and the tension spring and the positioning surface 3131 are located on the same side of the rotating shaft 32, and the tension provided by the tension spring can also drive the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 to rotate to abut against the positioning surface 3131 in the default state when not stepped on. For another example, the reset member 4 is a torsion spring, which is mounted on the rotating shaft 32 and connected to the pedal 33, and the torsion of the torsion spring can also drive the first pedal 331, the second pedal 332, the third pedal 333 and the fourth pedal 334 to rotate to abut against the positioning surface 3131 in the default state when not stepped on.

[0077] In other embodiments, the pedal assembly may not include the reset member 34, and the pedal 33 and the rotating shaft 32 are connected with a damping rotation. The doctor can switch the pedal 33 between the default state and the trigger state by stepping on both ends of the pedal 33. Under the action of the damping, the pedal 33 can stop in the default state and the trigger state respectively.

[0078] In this embodiment, the pedal assembly 3 also includes a plurality of sensors 35. For example, the pedal assembly 3 includes four sensors 35. At least one sensor 35 is provided for each pedal 33. The two sensors 35 corresponding to the first pedal 331 and the fourth pedal 334 are respectively electrically connected to the floating locking assembly 25, and the two sensors 35 corresponding to the second pedal 332 and the third pedal 333 are respectively electrically connected to the lifting drive assembly 22. A control device such as a control panel may be installed at the lower end of the detection bed, and the sensor 35, the lifting drive assembly 22 and the floating locking assembly 2 are respectively connected to the control device by signal. The control device may also be installed outside the detection bed, and the sensor 35, the lifting drive assembly 22 and the floating locking assembly 2 are respectively connected to the control device by signal through a wired or wireless manner.

[0079] The sensor 35 can be installed on the mounting base 31, and the sensor 35 is arranged close to the pedal 33. Specifically, the sensor 35 can be a contact sensor or a photoelectric sensor. The sensor 35 can be installed on the back plate 313 through the sensor mounting base 36. The sensor 35 is located above the positioning surface 3131. When the pedal 33 is stepped on and rotated, the end of the pedal 33 will contact or approach the sensor 35, so as to trigger the sensor 35 to generate a corresponding sensing signal. The sensing signals generated by the two sensors 35 corresponding to the first pedal 331 and the fourth pedal 334 are used to trigger the floating locking assembly 25 to unlock or lock the plane floating of the load-bearing platform 1. The sensing signals generated by the two sensors 35 corresponding to the second pedal 332 and the third pedal 333 are used to trigger the lifting drive assembly 22 to drive the load-bearing platform 1 to rise or fall.

[0080] In other embodiments, the sensor 35 may also be installed at other positions. For example, the sensor 35 is installed at a position of the bottom plate 311 close to the reset member 34. When the pedal 33 is stepped on, the sensor 35 may also be triggered to control the corresponding action.

[0081] In other embodiments, the pedal assembly 3 may not include the sensor 35. The pedal 33 is connected to the lifting drive assembly 22 and the floating locking assembly 25 through a transmission structure such as a pull rope. The lifting drive assembly 22 and the floating locking assembly 25 are provided with corresponding mechanical switches. The sensor 35 can also control the rise or fall of the supporting platform 1 and the floating unlocking and locking by operating the mechanical switch.

[0082] In the detection bed of the present embodiment, since the multiple pedals 33 in the pedal assembly 3 are installed on the same rotating shaft 32, the multiple pedals 33 are installed uniformly. Compared with the multiple pedals 33 being installed separately, the installation structure of the pedals 33 can be simplified and the difficulty of assembling the multiple pedals 33 can be reduced; and the multiple pedals 33 are installed on the same rotating shaft 32, so that the multiple pedals 33 can be located at the same height position based on the same rotating shaft 32, and it is easy to achieve that the upper surfaces of the multiple pedals remain flush, which is more beautiful.

[0083] Please refer to Figure 8 In one embodiment, the support device 2 of the testing bed may not include the floating locking assembly 25, the carrying platform 1 is fixedly connected to the support device 2, and the support device 2 is only used to drive the carrying platform 1 to rise and fall.

[0084] Correspondingly, the pedal assembly 3 includes two pedals 33, and the two pedals 33 are respectively used to trigger and control the supporting device 2 to drive the carrying platform 1 to rise and fall.

[0085] Please refer to Figure 5 In one embodiment, the pedal assembly further includes one or more spacers 37, which are mounted on the rotating shaft 32. The number of spacers 37 may be one less than the number of pedals 33. The spacer 37 is located between two adjacent pedals 33. The spacer 37 is used to separate the two adjacent pedals 33 to prevent the adjacent pedals 33 from being affected by being stepped on.

[0086] The separator 37 can be a separator structure such as a separator plate. The separator plate is perpendicular to the rotating shaft 32. The separator 37 is set as a plate structure, which can separate two adjacent pedals 33 and reduce the gap between the two adjacent pedals 33, which is more beautiful.

[0087] The separator 37 can be connected to the rotating shaft 32 through a mounting ring 38, the mounting ring 38 is sleeved on the rotating shaft 32, and the separator 37 and the mounting ring 38 can be fixedly connected by welding or the like. The separator 37 is connected to the rotating shaft 32 through the mounting ring 38, which can increase the area of ​​the connection between the separator 37 and the rotating shaft 32 and improve the stability of the connection between the two. Of course, the separator 37 is provided with a mounting hole, and can also be directly fixedly connected to the rotating shaft 32.

[0088] Please refer to Figure 5 In one embodiment, the partition 37 can be extended to be connected with the mounting seat 31, for example, the partition 37 is extended to be fixedly connected with the bottom plate 311, so that the partition 37 can also play a supporting and fixing role, increase the supporting and fixing points of the rotating shaft 32, and improve the stability of the installation of the rotating shaft 32.

[0089] The partition 37 may also be configured to be fixedly connected to the back plate 313 , and may also increase the supporting and fixing points of the rotating shaft 32 , thereby improving the stability of the installation of the rotating shaft 32 .

[0090] Please refer to Figure 5 and Figure 6 In one embodiment, a buffer pad 39 is further provided in the mounting seat 31. The mounting seat 31 may be provided with a plurality of buffer pads 39. The number of buffer pads 39 is the same as the number of pedals 33. Each pedal 33 is provided with a buffer pad 39. The buffer pad 39 is provided at one end of the bottom plate 311 away from the back plate 313. When the pedal 33 is stepped on and triggered, one end of the pedal 33 rotates relative to the rotating shaft 32 to contact the buffer pad 39, which can prevent one end of the pedal 33 from directly contacting the bottom plate 311, can buffer and avoid the problem of hard contact damage, and can also achieve a mute effect.

[0091] In other embodiments, the mounting seat 31 is provided with a long buffer pad 39 , which is equivalent to a collection of multiple buffer pads 39 . The long buffer pad 39 corresponds to all pedals 33 and can also achieve stepping buffering of multiple pedals 33 .

[0092] In one embodiment, an X-ray imaging system is provided. The X-ray imaging system includes a transmitting device, a receiving device and a detection bed in any of the above embodiments.

[0093] The transmitting device can be a suspended structure or a column structure. The transmitting device includes a mounting frame and a head. The head is moved by the mounting frame. The head is used to transmit X-rays to irradiate the object to be detected carried by the carrying platform 1.

[0094] The receiving device is a flat panel detector, which can be installed below or on the side of the carrying platform 1. The user receives the X-rays that pass through the object to be detected and generates X-ray data.

[0095] In this embodiment, since the multiple pedals 33 in the pedal assembly 3 of the launching device are installed on the same rotating shaft 32, the multiple pedals 33 are installed uniformly, which can simplify the installation structure of the pedals 33 and reduce the difficulty of assembling the multiple pedals 33 compared to the multiple pedals 33 being installed separately; and the multiple pedals 33 are installed on the same rotating shaft 32, so that the multiple pedals 33 can be located at the same height position based on the same rotating shaft 32, and it is easy to achieve that the upper surfaces of the multiple pedals are kept flush, which is more beautiful.

[0096] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
