The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

Referring to FIGS. 1-3 , the present application provides a centrifugal motor 100 , the centrifugal motor 100 can generate centrifugal force, so that the device on which the centrifugal motor 100 is installed can adjust the angle under the action of the centrifugal force. The centrifugal motor 100 includes a casing 10 , a rotating shaft 20 rotatably connected to the casing 10 , a fixed sleeve 22 disposed on the rotating shaft 20 , a rotating block 30 partially accommodated in the fixed sleeve 22 , and a drive rotatably connected to the rotating shaft 20 . Institution 50.

Specifically, in the first embodiment of the present application, the housing 10 is provided with a limiting member 12, and the limiting member 12 is provided with an outlet 124, and the housing 10 is further provided with a permanent magnet 70 or a magnetic coil ( not shown). The rotating shaft 20 is rotatably connected with the housing 10 , and the rotating shaft 20 is provided with a fixing sleeve 22 , and the fixing sleeve 22 forms an accommodating cavity, and the fixing sleeve 22 defines an opening 224 that communicates with the accommodating cavity. The rotating block 30 is accommodated in the accommodating cavity of the fixing sleeve 22 of the rotating shaft 20 . Further, in the embodiment shown in FIG. 4 , the bottom of the fixing sleeve 22 is communicated with the outlet 124 of the limiting member. In other embodiments, the fixing sleeve 22 Bottom can also be set. Specifically, the rotating block 30 is a magnetic body, such as a metal block, a permanent magnet, or a permanent magnet or the like is provided inside the rotating block 30 . And a part of the rotating block 30 is located outside the opening 224 , so that the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20 . The driving mechanism 50 is connected with the rotating shaft 20 to rotate the rotating shaft 20 and drive the fixed sleeve 22 and the rotating block 30 to rotate relative to the casing 10 .

At the same time, referring to FIG. 4, the following explains the cooperation process between the various components during the rotation of the rotating shaft 20: the permanent magnet 70 or the magnetic coil fixed on the housing 10 attracts the rotating block 30, so that the rotating block 30 is partially located in the rotating block 30. Outside the opening 224, under the action of the driving mechanism 50, the rotating shaft 20 rotates relative to the casing 10. When the rotating shaft 20 starts to rotate, a part of the rotating block 30 is located outside the opening 224 of the fixed sleeve 22. As the rotating shaft 20 rotates, the rotating block 30 is also rotated, so that the part of the rotating block 30 outside the opening 224 abuts against the limiting member 12, so that the limiting member 12 squeezes the rotating block 30, thereby making the rotating block 30 away from the permanent magnet 70 or the magnetic coil and toward the fixed sleeve 22. The accommodating cavity moves so that the center of gravity of the rotating block 30 coincides with the axis line of the rotating shaft 20. As the rotating shaft 20 continues to rotate, when the opening 224 of the fixed sleeve 22 is not blocked by the limiting member 40 to the outside, the rotating block 30 is blocked by the rotating block 30. The magnetic attraction of the permanent magnet 70 or the magnetic coil is again partially outside the opening 224 .

Assuming that the time for one rotation of the rotating shaft 20 is one cycle, a part of the rotating block 30 is located outside the opening 224 during a part of one cycle during the one rotation of the rotating shaft 20 . It can be understood that in the process of pressing the rotating block 30 against the limiting member 12 , the rotating block 30 moves away from the permanent magnet 70 or the magnetic coil and enters the accommodating cavity of the fixing sleeve 22 . When the rotating block 30 is partially located outside the opening 224 of the fixed sleeve 22, the center of gravity of the rotating block 30 does not coincide with the axis line of the rotating shaft 20. At this time, the rotating block 30 will generate a centrifugal force as the rotating shaft 20 rotates. Then the electronic device using the above centrifugal motor 100 can make the rotating shaft 20 rotate when the electronic device is detected to fall, and the angle of the electronic device can be adjusted by the centrifugal force generated by the centrifugal motor 100, so that the preset surface of the electronic device faces the preset surface. A collision object is set to prevent the fragile parts of the electronic device from contacting the preset collision object first. Thus, the probability of breaking the screen of the electronic device is reduced.

Referring to FIG. 5 , it is a schematic diagram of the centrifugal force generated by the rotating block 30 when the rotating shaft 20 rotates once. In this embodiment, when the rotating shaft rotates to 270°-360°, a part of the rotating block 30 is located outside the opening 224, and the rotating block 30 rotates to generate centrifugal force. Between 0 and 270 degrees, the entire rotating block 30 is located in the accommodating cavity, and the center of gravity of the rotating block 30 coincides with the axis line of the rotating shaft 20, so the rotating block 30 does not generate centrifugal force during this period. That is to say, every time the rotating shaft 20 rotates once, the rotating block 30 generates a pulse of centrifugal force. In the process of adjusting the angle of the electronic device, at least one pulse of centrifugal force, or multiple pulses of centrifugal force is required.

In one implementation, specifically, the limiting member 12 includes two arcuate claws 122 disposed opposite to each other. The two arcuate claws 122 constitute the outlet 124 , and the portion of the rotating block 30 located outside the opening 224 is also located at the outlet 124 . That is to say, the opening 224 and the outlet 124 communicate with each other, and the part of the rotating block 30 located outside the opening 224 is surrounded by the two arc claws 122 . The part of the rotating block 30 at the opening 224 abuts against the arc claw 122 during the rotation process, and the arc claw 122 squeezes the rotating block 30 to move the rotating block 30 into the fixed sleeve 22 . Further, in one embodiment, the diameter of the outlet 124 is larger than the width of the portion of the rotating block 30 outside the opening 224 , so that the rotating block 30 rotates relative to the housing 10 by a predetermined angle and then collides with the arc claw 122 . In a period corresponding to one rotation of the rotating shaft 20, the rotating block 30 stays outside the opening 224 for a long time, that is, the rotating block 30 generates centrifugal force for a long time.

In other embodiments, the diameter of the outlet 124 can also be only slightly larger than the width of the part of the rotating block 30 located outside the opening 224, so that the part of the rotating block 30 located outside the opening 224 can just pass through, so that the rotating shaft 20 starts to rotate and rotates. The portion of the block 30 outside the opening 224 immediately contacts the arcuate pawl 122 . In different embodiments, the diameter of the outlet 124 may be specifically limited according to actual requirements.

3 and 6 , specifically, in an embodiment, the housing 10 further includes a sleeve 14 , the sleeve 14 is fixedly connected with the limiting member 12 , and the rotating shaft 20 is partially located in the sleeve 14 . Specifically, the shape of the sleeve 14 may be a cylindrical shape, a rectangular parallelepiped, or other shapes, as long as it has a cavity for a part of the rotating shaft 20 to pass through. A part of the rotating shaft 20 is passed through the sleeve 14 , and at the same time, the fixing sleeve 22 on the rotating shaft 20 is located in the outlet 124 of the limiting member 12 .

In one embodiment, a support member 142 extends from the sleeve 14 or the limiting member 12 , and a part of the support member 142 is located opposite to the outlet 122 of the limiting member 12 , and the support member 142 is used for fixing the permanent magnet 70 or the magnetic coil. . A schematic diagram of the sleeve 14 extending out of the support 142 is shown in FIG. 3 .

Further, in another embodiment, a gap 16 is formed between the sleeve 14 and the limiting member 12 , the fixing sleeve 22 is provided with a first fixing ring 24 in the direction of the axis of the rotating shaft 20 , and the first fixing ring 24 is located in the gap 16 , so that the first fixing ring 24 is sandwiched between the end face of the sleeve 14 and the fixing sleeve 22 . With such a structure, the first fixing ring 24 can prevent the rotating shaft 20 from being separated from the housing 10 by force in the longitudinal direction of the rotating shaft 20 , and at the same time, the part of the rotating shaft 20 located in the sleeve 14 can prevent the rotating shaft 20 from being perpendicular to the length of the rotating shaft 20 . The directional force is separated from the housing 10 . It can be understood that under the combined action of the first fixing ring 24 and the part of the rotating shaft 20 located in the sleeve 14 , it is ensured that the entire rotating shaft 20 will not be separated from the casing 10 under any force in any direction, and the structure is very stable.

Further, in another embodiment, the fixing sleeve 22 is provided with a first fixing ring 24 and a second fixing ring 26 on both sides of the axis line of the rotating shaft 20 , the first fixing ring 24 is located in the gap 16 , and the arc claw 12 between the first and second fixing rings 24 and 26 . With such a structure, the rotation shaft 20 can be combined with the housing 10 more firmly.

Specifically, in different embodiments, the housing 10 and the limiting member 12 may be integrally formed or detachably connected, such as glued or screwed. It can be understood that the part of the rotating shaft 20 located in the sleeve 14 and the first fixing ring 24 can be integrally formed or detachably connected, such as glued or threaded connection. mounted on the housing 10 . Taking the threaded connection between the part of the rotating shaft 20 located in the casing 14 and the first fixing ring 24 as an example, when installing, the first fixing ring 24 can be placed at the gap 16 first, and at the same time, the fixing ring 24 with the rotating block 30 can be fixed. The sleeve 22 is located in the outlet 124 , and finally, the part of the rotating shaft 20 located in the sleeve 14 is threadedly connected to the first fixing ring 24 through the sleeve 14 to be fixed. In other embodiments, other connection manners may also be used, and details are not described herein.

In one embodiment, the first fixing ring 24 and the second fixing ring 26 are annular, and a through groove 262 is formed in the middle for connecting the rotating block 30 .

In one embodiment, the housing 10 of the present application further includes a handle 18 integrally formed with the sleeve 14 and the limiting member 12 , as shown in FIG. 3 , a through hole is formed on the handle 18 . The handle 18 is provided mainly to facilitate the installation of the centrifugal motor 100 to other devices. In other embodiments, the above-mentioned handle 18 may not be included, for example, an accommodating hole is opened on the device to be installed, and the installation can be performed by interference fit or fixed connection by an adhesive layer.

In one embodiment, in the centrifugal motor 100 provided by the present application, the width of the part of the rotating block 30 located in the accommodating cavity of the fixed sleeve 22 is greater than the width of the opening 224 of the fixed sleeve 22, so as to avoid the entire rotating block 30 being affected by the permanent magnet 70 or The attractive force of the magnetic coil pulls out the fixing sleeve 22 . In the embodiment shown in FIG. 3 , the rotating block 30 includes a base body 32 and an extension portion 34 extending from the base body 32 along the axis of the rotating shaft 20 . The width of the extending portion 34 is greater than the width of the opening 224 of the fixing sleeve 22 . In other embodiments, the rotating block 30 may also have other shapes, which are not intended to limit the present invention, for example, a cylinder or an irregular elongated shape.

In this embodiment, the driving mechanism 50 is a magnetic coil, and the rotating shaft 20 is partially sleeved in the driving mechanism 50 of the magnetic coil. That is to say, when the rotating block 30 needs to generate centrifugal force, the magnetic coil is energized, and after the magnetic coil is energized, a magnetic force acts on the rotating shaft 20 to make the rotating shaft 20 rotate, thereby driving the rotating block 30 to rotate. It can be understood that the part of the rotating shaft 20 located in the sleeve 14 contains a permanent magnet rotor. It should be noted that the magnetic coil here is located in the sleeve 14 , which is different from the magnetic coil on the support member 142 .

Optionally, in other embodiments, the driving mechanism 50 may also be other types of other motors capable of generating power, such as motors.

As shown in FIG. 7 and FIG. 8 , in the second embodiment of the present application, the difference between this embodiment and the first embodiment is that the casing 10 of the centrifugal motor 200 is not provided with a limiting member, and is not on the casing 10 A permanent magnet or a magnetic coil is provided, but a magnetic coil 80 is provided at the position of the bottom of the fixing sleeve 22 opposite to the opening 224 . Since the rotating block 30 is a magnetic body, the magnetic coil 80 generates periodic repulsive force and attractive force to act on the rotating block 30 , so that the rotating block 30 is periodically partially located outside the opening 224 , thereby causing the center of gravity of the rotating block 30 to periodically deviate from the rotating shaft 20 the axis line. When the magnetic coil 80 generates a repulsive force to the rotating block 30, the rotating block 30 is repelled by the repulsive force and has a part located outside the opening 224 of the fixed sleeve 22, and the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20; When an attractive force is generated on the rotating block 30 , the rotating block 30 is pulled back into the fixed sleeve 22 by the attractive force. At this time, the center of gravity of the rotating block 30 coincides with the axis line of the rotating shaft 20 .

That is to say, for each rotation of the rotating shaft 20 , a part of the rotating block 30 is located outside the opening 224 of the fixing sleeve 22 within an angular range. When the center of gravity of the rotating block 30 deviates from the axis line of the rotating shaft 20, and a part is located outside the opening 224, a pulse of centrifugal force is generated, that is, the rotating block 30 generates a pulse of centrifugal force for each rotation of the rotating shaft 20. In the process of adjusting the angle of the electronic device, at least one pulse of centrifugal force, or multiple pulses of centrifugal force is required. It is the same as the related description of the first embodiment above, and will not be repeated here.

Further, in other embodiments, the magnetic coil 80 may also be arranged in the first fixing ring 24 and/or the second fixing ring 24, below the extension portion 34 of the rotating block 30, or at the same time in the first fixing ring 24 and/or at the same time. Or the bottom of the second fixing ring 24 and the fixing sleeve 22 are provided with the magnetic coil 80 .

Of course, in other embodiments, the limiting member can also be changed into a supporting member, which is used to carry the fixed sleeve without conflicting with the rotating block.

As shown in FIGS. 9 and 10 , in the third embodiment of the present application, the difference between this embodiment and the first embodiment is that the limiting member 12 is retained on the casing 10 of the centrifugal motor 300 , but not on the casing. A permanent magnet or a magnetic coil is provided on the 10 , but a permanent magnet 90 or a magnetic coil (not shown) is provided in the fixed sleeve 22 at a relative position of the opening 224 . And the rotating block 30 is also a magnetic body. The difference from the above embodiment is that in this embodiment, the permanent magnet 90 or the magnetic coil generates a repulsive force to act on the rotating block 30, so that the rotating block 30 is partially located outside the opening 224, thereby making the rotating block 30. The center of gravity of the 30 deviates from the axis line of the rotating shaft 20 periodically; the rotation of the rotating shaft 20 drives the rotating block 30 to rotate, and the limiter 12 pushes the rotating block 30 to move into the fixed sleeve 22, so that the center of gravity of the rotating block 30 is aligned with the axis of the rotating shaft 20. The center lines coincide, and as the rotating shaft 20 continues to rotate, the rotating block 30 is partially located outside the opening 224 again by the repulsive force generated by the magnetic coil or the permanent magnet 90 . The related principle description is the same as that of the other embodiments above, which is not repeated here.

It can be understood that, in an embodiment, if permanent magnets 90 are provided in the fixed sleeve 22, the rotating block 30 itself is a permanent magnet, or the rotating block 30 containing the permanent magnets and the permanent magnets 90 in the fixed sleeve 22 are magnetic. If they repel each other, the rotating block 30 is always subjected to a repulsive force. In another embodiment, a magnetic coil is arranged in the fixed sleeve 22, and the magnetic coil can be controlled to generate a repulsive force on the rotating block 30 all the time, or during the rotation of the rotating shaft 20, the rotating block 30 is not repelled for a short period of time. Forces, such as when the rotating block 30 is required to move back into the fixed sleeve 22 .

Further, in other embodiments, the permanent magnet 90 or the magnetic coil may also be arranged in the first fixing ring 24 and/or the second fixing ring 24, below the extension 34 of the rotating block 30, or at the same time in the first fixing ring 24 and/or the bottom of the second fixing ring 24 and the fixing sleeve 22 are provided with permanent magnets 90 or magnetic coils.

Referring to FIG. 11 , the present application further provides an electronic device 400 having the centrifugal motor 100 , 200 or 300 described in any of the above embodiments. Specifically, the electronic device 400 in this application may be a mobile phone, an IPad, a smart wearable device, a digital audio and video player, an electronic reader, a handheld game console, a vehicle-mounted electronic device, a digital camera, a flash memory disk, and the like.

Referring to FIG. 12, optionally, in an embodiment, the centrifugal motor 100 installed in the electronic device 400a includes a first centrifugal motor 100a and a second centrifugal motor 100b, and the first and second centrifugal motors 100a and 100b are respectively fixed to the electronic device 400a. The centrifugal force generated by the rotating blocks of the first and second centrifugal motors 100a and 100b on opposite sides in the length direction of the device 400a at least have components in opposite directions. The different cases are as follows:

For example, the direction of the centrifugal force generated by the first centrifugal motor 100a acting on the electronic device 400a is opposite to the direction of the centrifugal force generated by the second centrifugal motor 100b acting on the electronic device 400a. For example, one centrifugal force is perpendicular to the display screen of the electronic device 400a upward, and the other centrifugal force is perpendicular to the display screen of the electronic device 400a downward, which is equivalent to one centrifugal force pulling upward, and the other centrifugal force pulling downward. The directions of the two centrifugal forces are opposite, so that the electronic device 400a can adjust the angle more quickly, for example, the electronic device 400a can be adjusted to a downward angle of the display screen, and the display screen can be adjusted to an upward angle to avoid the collision of the display screen when the electronic device 400a touches the ground. On the ground, reduce the chance of the display breaking.

Optionally, in another embodiment, the first and second centrifugal motors 100a and 100b are respectively fixed on opposite sides of the electronic device 400b in the width direction, as shown in FIG. 13 .

In other embodiments, the directions of the centrifugal forces generated by the first and second centrifugal motors 100a and 100b may not be completely opposite, as long as the respective component forces of the two centrifugal forces are opposite in the same direction.

Referring to FIG. 14, in another embodiment, at least two centrifugal motors 100c are installed on an electronic device 400c, the two centrifugal motors 100c are arranged side by side, and the centrifugal forces generated by the rotating blocks of the two centrifugal motors 100c are in the same direction. In another embodiment, the centrifugal forces generated by the rotating blocks of the two centrifugal motors 100c may each have the same component force in at least one direction. With such a structure, the two parallel centrifugal motors 100c can generate larger or more continuous centrifugal force to act on the electronic device 100a, that is, two centrifugal forces can be generated in one rotation of the rotating shaft. Specifically, the centrifugal force of the two pulses generated by the two centrifugal motors 100c can be in the same time period or in different time periods, so that the angle of the electronic device 100a can be adjusted more quickly.

It can be understood that, in other embodiments, the number of centrifugal motors 100c arranged side by side may also be three or more, which is not specifically limited.

Referring to FIG. 15, further, in another embodiment, at least two centrifugal motors 100d are arranged side by side on opposite sides of the electronic device 400d in the length direction, or on the opposite sides in the width direction of the electronic device 400d, respectively, and the side-by-side on the same side The centrifugal force generated by the centrifugal motors 100d has at least a component force in the same direction, while the centrifugal force generated by the side-by-side centrifugal motors 100e on the other side is in the opposite direction to the centrifugal force generated by the side-by-side centrifugal motors 100d on one side. For example, the centrifugal force generated by the at least two centrifugal motors 100d arranged side by side near the top camera side of the electronic device 400d is vertically upward on the display screen, while the centrifugal force generated by the at least two centrifugal motors 100d arranged side by side near the bottom button side of the electronic device 400d The centrifugal force is perpendicular to the display screen downward, and the forces in the two directions act together on the electronic device, and the adjustment speed is faster. It can be understood that the directions of the centrifugal forces generated by the at least two centrifugal motors 100d disposed side by side near the top camera of the electronic device 400d may not be exactly the same, as long as each centrifugal force has a component force in the same direction. The centrifugal forces generated by the at least two centrifugal motors that are arranged side by side near the button side of the bottom of the electronic device 100b may not be exactly the same, which will not be repeated here.

It can be understood that, in an embodiment, the centrifugal force component of the centrifugal force generated by the side-by-side centrifugal motors 100e on the other side of the electronic device 400d is in the opposite direction to the centrifugal force generated by the side-by-side centrifugal motors 100d on the side of the electronic device 400d. Can.

Optionally, in different embodiments, three centrifugal motors may also be provided on one electronic device 400e. For example, in one embodiment, one centrifugal motor 100f is located at the top of the electronic device 400e, and the other two centrifugal motors 100f are arranged side by side at the bottom of the electronic device 400e, as shown in FIG. 16 . In another embodiment, the first centrifugal motor 100g is located at the top of the electronic device 400f, the second centrifugal motor 100g is located at the bottom of the electronic device 200c, and the third centrifugal motor 100g is located at the middle edge of the electronic device 400f, as shown in FIG. 17 . shown. In other embodiments, the positions of the three centrifugal motors 100 on the electronic device 200 can be adjusted according to actual needs. Specifically, the direction of the centrifugal force generated by the three centrifugal motors 100 is the same as the setting principle of the above embodiment, mainly because the multiple centrifugal forces act together on the electronic device 200 to speed up the adjustment of the electronic device 200 , which is not repeated here. Of course, in other embodiments, a larger number of centrifugal motors 100 may be provided as required.

The present application also provides a method for adjusting the angle of the electronic device during the falling process of the electronic device, which is applied to the electronic device described in any of the above embodiments. FIG. 18 is a schematic flowchart of an embodiment of the method of the present application. Methods include:

101: Determine whether the electronic device is in a falling process.

In one embodiment, an acceleration sensor is set in the electronic device, and if the acceleration sensor detects the generation of gravitational acceleration, that is, the electronic device is in a free fall state, it is determined that the electronic device is in a falling state. Specifically, in different embodiments, it can be determined by the change of the acceleration in the direction of gravity of the electronic device and the time when the acceleration is generated. This is not elaborated.

102 : If the electronic device is in the process of falling, start the centrifugal motor so that the rotating block of the centrifugal motor generates centrifugal force to adjust the angle of the electronic device so that the preset surface of the electronic device faces the preset collision object.

When the centrifugal motor starts, the rotating shaft rotates, which drives the rotating block to rotate eccentrically, thereby generating centrifugal force, which acts on the electronic device, so that the preset surface of the electronic device faces the preset collision object. Specifically, the preset surface of the electronic device is a surface that is relatively unbreakable or relatively impact-resistant, such as the back of the electronic device, or the surface with a protective cover. In different embodiments, the user can set a surface by himself according to the actual structure of the electronic device, or a part is a preset surface. The collision object generally refers to the ground, and may also be a wall or a tree trunk in other embodiments, for example, when the user falls and the electronic device is thrown out by force.

FIG. 19 is a schematic flow chart of the steps of the method in another embodiment. The method includes steps 201 to 204, wherein steps 201 and 202 are consistent with the above-mentioned embodiments, which will not be repeated here. The following focuses on steps 203 and 204:

201: Determine whether the electronic device is in a falling process.

202 : If the electronic device is in the process of falling, start the centrifugal motor, so that the rotating block of the centrifugal motor generates centrifugal force, so as to adjust the angle of the electronic device, so that the preset surface of the electronic device faces the preset collision object.

203 : Determine whether the electronic device is adjusted so that the preset surface faces the preset collision object.

The distance change between the preset surface and the preset collision object, and the distance change between the side opposite to the preset surface and the preset collision object are detected by the distance sensor, if the distance between the preset surface and the preset collision object changes The change and the change trend of the distance between the side opposite to the preset surface and the preset collision object are the same, for example, they are getting smaller and smaller, and the distance ratio between the preset surface and the preset collision object is the same as the preset surface. If the distance between the back side and the preset collision object is smaller, it is determined that the electronic device has been adjusted so that the preset surface faces the preset collision object. In other embodiments, the variation of the distance and the light conditions of the predetermined surface and the surface position of the surface opposite to the predetermined surface may also be used. For example, if the distance between the preset surface and the preset collision object changes and the distance between the side opposite to the preset surface and the preset collision object changes in the same trend, for example, they are getting smaller and smaller, and the preset surface If the light on the surface is opposite to the light on the surface of the surface opposite to the preset surface, it is determined that the electronic device has been adjusted so that the preset surface faces the preset collision object.

204: If yes, turn off the centrifugal motor.

Since the electronic device has been adjusted so that the preset surface faces the preset collision object, it is only necessary to turn off the centrifugal motor at this time, so that the preset surface of the electronic device can touch the collision object instead of the fragile surface of the electronic device. Protect electronic devices well.

The present application also provides a device with a storage function, storing program data, and when the program data is executed, the methods described in the above embodiments are implemented. Specifically, the above-mentioned device with a storage function may be one of a personal computer, a server, a network device, or a USB flash drive.

The above description is only an embodiment of the present application, and is not intended to limit the scope of the patent of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present application, or directly or indirectly applied to other related technologies Fields are similarly included within the scope of patent protection of this application.
