The gas moves into the distributor 500 and is expelled back to the external environment 150. Fluid flow in the operating state is shown by the dashed line with thick arrows. This operating state is Even if a pressure change to the nozzle 200 and / or fluid container 400 is not required, the fluid Keep the pumped fluid moving through distributor 500 and "start" This can be used as a "standby" or "steady" operating state. Fluid entering from the boundary 150 (e.g., atmosphere) passes through the filter 702 and the connector inlet 70 2I into connector 700. If necessary or desired, a filter 702 may be removable, replaceable, and / or otherwise cleanable (e.g., as, to maintain adequate air intake into the system from the external environment 150). While any desired intake size may be used, in some embodiments of the present technology, The Ruta 702 is at least 50mm 2 Area of ​​50mm 2 ~100mm 2 Area of ​​50m m 2 ~150mm 2 area of ​​25mm 2 ~250mm 2 Area or other desired The filter may have an area of ​​0.05 mm or less, such as a flat sheet of filter material, a flat screen, or the like. Any desired type of filter media, filter structure, and / or filter material may be used. The filter 702 may provide a relatively large exterior area for the connector 700, e.g. As shown in FIGS. 5A to 5E, 11A, 12A, and 13B, 702. Additionally or alternatively, if desired, a filter may be provided within connector 700 and / or , may be provided elsewhere in the fluid flow path (e.g., at least partially through connector 70 A pump (or pumps) extending inside the body and at least partially inside the dedicated fluid path 702P. (Several locations are possible) Somewhere before the entrance to 600H, 600F, etc.

[0051] Fluid flows from connector inlet 702I through the connector body (e.g., fluid path 702 P or through the interior open space 710 inside the connector 700), and In some embodiments of the present technology, the dedicated fluid path 702P ( For example, a closed fluid tube) may be omitted (or the interior space 710 of the connector 700 may be omitted). (the end of the connector 702 is made discontinuous with the internal open end), so that fluid can flow from the connector inlet 702I to the internal open end. The openings provided as ports 702O may be inserted into the space 710 and / or In such an embodiment, the internal open space 710 may be vented. Source 710 may be considered at least a portion of fluid path 702P through connector 700. Port 702O connects to fluid pathway 604, which delivers fluid to a pumping system (in this embodiment). In the example, pump(s) 600H, 600F and fluid lines connecting the pumps. 602). Fluid flows down fluid line 606 from pump(s) 600H, 600F, A one-way valve along the fluid line 606 leads back to the inlet port 704 of the connector 700. Alternatively, the check valve may be connected to the connector inlet port 704 and / or the fluid line 60 6 to prevent fluid from flowing back toward pump(s) 600H, 600F. Fluid may be present in the connector inlet port 704 to the connector fluid path 704. P (also referred to herein as the "fourth connector fluid path") through connector 700. Connector outlet port 704O (also referred to herein as the "fourth fluid pathway connector") )) and into inlet fluid port 800A of manifold 800. Fluid flows from inlet fluid port 800A through fluid inlet path 802 in manifold 800. 800I and into the fluid transfer system 900. In the embodiment, the fluid exits the fluid transfer system 900 and passes through the first manifold port 804. and through a first manifold fluid flow path 806 defined in the manifold 800 to another The first fluid path connector (or port) 706, through a first connector fluid path 708, and optionally , to the external environment 150. Additionally or alternatively, through first fluid pathway connector 706 The fluid passing through may flow into (and thereby into) the interior space 710 within the connector 700. and / or may be utilized as a separate pump cycle.

[0052] Alternatively, in some embodiments of the present technology, the fluid may simply be ejected in this operating state. At each step, the fluid distributor 5 Instead of continuously moving fluid through the pump(s) 600H, 600 A selectively operable fluid path may be provided that discharges directly from F into the external environment 150. Another option is to use the pump(s) if no change in fluid pressure is required. 600H, 600F could be stopped.

[0053] FIG. 5B shows an operating state in which fluid is drawn from the external environment 150 to the fluid drain. The feet are then transported into the striator 500 and transferred to the foot support bladder 200. , the fluid flow in this operating state is shown by the dashed line with thick arrows. for a more stable feeling and / or for more strenuous activities (such as running), This can be used to increase the pressure in the foot support bladder 200. In this operating state: Fluid entering from the external environment 150 (e.g., atmosphere) is introduced into the ventilator 100 in the same manner as described above for FIG. 5A ( and through the same components), through connector 700, through manifold 800 and into the fluid transfer system 900. However, in this operating state, the fluid The fluid exits the body transfer system 900, passes through the second manifold port 808, and enters the manifold 800 through a second manifold fluid flow path 810 defined in another manifold port. through port 800C to second fluid pathway connector (or port) 712 of connector 700 7, through a second connector fluid path 714, through another connector port 720, and to the foot support. The fluid passes into the fluid line 202 and into the foot support bladder 200 .

[0054] In some applications, the foot support bladder 200 may be configured to reduce pressure in the foot support bladder. It may be desirable to remove fluid from ladder 200 (e.g., to provide a softer feel). For less strenuous activities such as walking or casual wear An example of this operating condition is shown in FIG. 5C, and the fluid flow is indicated by a dashed line with a thick arrow. In this operating state, fluid exits the foot support bladder 200 and enters the foot support fluid line. 202 and into the second connector fluid path 714 via connector port 720. and to a second fluid pathway connector 712 of connector 700.

The first connector fluid passage is caused by the fluid reaching the first connector fluid passage (which may form the internal space 710 of the first connector). The fluid connector (or port) 706 allows for the release of fluid, thereby allowing fluid to flow throughout the system. A port may be formed to allow fluid to be discharged from the body (a "fluid discharge port") and back into the connector 700.

In this operating state, This reduces the fluid pressure in the fluid container 400, allowing the fluid to escape from the fluid container 400 to the external environment. 150. Fluid flow in this operating state is indicated by the dashed line with thick arrows. In this operating state, fluid exits the fluid reservoir 400 and enters the fluid reservoir fluid line 402. into the third connector fluid path 716 via connector port 722; and The fluid flows through a third fluid path connector (or port) 718 of the connector 700. From the body passage connector 718, through the manifold port 800D and into the manifold 800 into the third manifold fluid flow path 812 defined in the third manifold through port 814 and into fluid transfer system 900. From here, this example In the exemplary system and in operation, the fluid is discharged to the external environment 150. The fluid exits the fluid transfer system 900, passes through the first manifold port 804, and enters the manifold through a first manifold fluid flow path 806 defined in the manifold 800; 800B to the first fluid pathway connector (or port) 706 of the connector 700. and through the first connector fluid path 708 to the external environment 150 (which environment is the connector This is caused by a fluid reaching the interior space 710 within the heater 700.

It may be desirable to adjust (and in this example increase) the fluid pressure with This reduces the effect on fluid flow from pressure spikes caused by foot contact with the ground, Transport can be predicted or controlled over time. An example of this operating state is shown in FIG. 5E. In this operating state, fluid exits the fluid reservoir 400 and enters the fluid reservoir fluid line 402. into the third connector fluid path 716 via connector port 722; and The fluid passes through the third fluid pathway connector 718 of the connector 700. From port 718, through manifold port 800D, The fluid then enters the third manifold fluid flow path 812 and passes through the third manifold port 814. and into the fluid transfer system 900. From here, this exemplary system, In operation, fluid is transferred to the foot support bladder 200. This is the fluid transfer system 900, passes through second manifold port 808, and is defined in manifold 800. through the manifold port 800C through the second manifold fluid flow path 810 , leading to a second fluid path connector 712 of the connector 700 and forming a second connector fluid path 714. through to connector port 720, into foot support fluid line 202, and The pressure is generated by the fluid entering the retaining bladder 200.

In this state, fluid entering from the external environment 150 (e.g., the atmosphere) passes through the filter 702 and The fluid enters connector 700 via connector inlet 702I. 2I through the connector body to the connector outlet port 702O and Path 604, which directs the fluid to a pump system (pump(s) 600H, 600H). The fluid travels down the fluid line 606 from the pump(s) 600H, 600F. A one-way valve along the fluid line 606 leads back to the inlet port 704 of the connector 700. Alternatively, the check valve may be connected to the connector inlet port 704 and / or the fluid line 606.

The present invention provides additional information about the fluid distribution system according to an aspect of the present technology. The foot support system, the sole structure, and the fluid transfer system are This discussion is provided and may be used in an article of footwear 100 including the Assume the following: (a) Manifold port 800A is connected to pump(s) 6 600H, 600F, etc. (e.g., connector ports 702I, 70 4O, and via its ports or other appropriate fluid line connecting components) (b) manifold port 800B; In fluid communication with the external environment 150 (e.g., connector port 706 and fluid path 708, and / or via other suitable fluid lines) any superfluids in the fluid transfer system 900A.

[0109] As previously mentioned, in this exemplary fluid distributor 500, the valve stem 910 The fluid distributor 500, foot support system, and so on can be rotated and moved to different positions. 100. The footwear structure 104 and / or the article of footwear 100 may be placed in different operating states. In the illustrated embodiment, the valve stem 910 rotates. This allows for six different operational states as shown in Figures 30A to 30G. OA can be clockwise (e.g., from operational state 1 to operational state 6) or counterclockwise (e.g., from operational state 6 to 9A and 9B show schematic diagrams of various positions of the valve stem 910 as it rotates from one position to another (to operational state 1). In accordance with aspects of the technology, in some pressure control methods, the "standby" state is rarely This may be a representative state when no pressure change occurs. Rotate to enter the desired operating state (e.g., operating state 2-6) and ensure the pressure reaches the desired level (pressure sensor). 850A, 850B) and then It rotates and returns to standby mode.

[0110] In this embodiment, the operating state 1 is a "standby" or "idle" state. In the example, the fluid pumped at each step is pump(s) 600 H, 600F through manifold 800, through fluid transfer system 900A, Simply pass through the system, through the hold 800 and back, and into the external environment 150. See Figure 30B. Operating State 1 is an example where a foot-actuated pump is used. , and any of the entire foot support system when actuated to move fluid during each step. This prevents any part of the valve from being overpressurized.

[0111] Operating state 2 (e.g., state in which the valve stem 910 is rotated 60 degrees clockwise from operating state 1) moves fluid from the pump(s) (or other fluid source) to the foot support bladder 200. In Operating State 2, the amount of fluid pumped during the step is The fluid passes through the system (e.g., pump(s) 600H, 600F to the manifold) through manifold 800, through fluid transfer system 900A, and back through manifold 800. ), and into the foot support bladder 200. See FIG. 30C. This operating state is It can be used to quickly and / or directly increase fluid pressure in the ladder 200. (eg, the "inflated" configuration of the foot support bladder 200).

[0112] Operating state 3 (e.g., the valve stem 910 is rotated 60 degrees clockwise from operating state 2) This is the "live" state, which transfers fluid from the foot support bladder 200 to the external environment 150. In state 3, fluid passes through the system (e.g., from the foot support bladder 200 to the manifold 8). 00, through fluid transfer system 900A, and back through manifold 800), and to the external environment 150. See FIG. 30D. This operating state is can be used to release fluid and reduce fluid pressure (e.g., leg support bras) Da 200 "contracted" configuration).

[0113] Operating state 4 (e.g., rotating the valve stem 910 clockwise by 60 degrees from operating state 3) It is also a "live" state that transfers fluid from the fluid container 400 to the external environment 150. In state 4, fluid passes through the system (e.g., from fluid reservoir 400 to manifold 800). through the fluid transfer system 900A and back through the manifold 800), and , to the external environment 150. See FIG. 30E. This operating state expels fluid and This may be used to reduce the fluid pressure in the fluid reservoir 400 (e.g., to reduce the "constriction" of the fluid reservoir 400). (condensed configuration).

[0114] Operating state 5 (e.g., the valve stem 910 is rotated 60 degrees clockwise from operating state 4) It is also in a "live" state, transferring fluid from the fluid reservoir 400 to the foot support bladder 200. In operating state 5, fluid passes through the system (e.g., from fluid reservoir 400 to manifold 8). 800 through fluid transfer system 900A and back through manifold 800), and and into the foot support bladder 200. See FIG. 30F. This operating state is By displacing fluid from the foot support bladder 200 into the foot support bladder 200, the fluid pressure in the foot support bladder 200 This action can be used to increase the leg support pressure (e.g., the "inflated" configuration of the foot support bladder 200). The condition requires the user to perform one or more steps to activate the pump 600H, 600F. The fluid pressure in the foot support bladder 200 can be changed without the need for a foot support bladder (e.g., while the user is standing). (or sitting motionless and / or resting your legs). Large pressure spikes resulting from the wearer landing or jumping can cause this operating condition The inside is isolated from direct fluid communication with the foot support bladder 200 (e.g., a foot-actuated pump) (Because fluid line 606 from fluid lines 600H, 600F is closed), this movement The operating state allows for improved control and fine adjustment of pressure changes in the foot support bladder 200. do.

[0115] Operating state 6 (e.g., the valve stem 910 is rotated 60 degrees clockwise from operating state 5) A “pump” pumps fluid from pump(s) (or other fluid source) to fluid container 400. In Operating State 6, fluid is passing through the system (e.g., pumps (multiple (possible) From 600H, 600F through manifold 800, fluid transfer system 900A 30) and into the fluid container 400. See G. This operating state quickly and / or directly increases the fluid pressure in the fluid vessel 400. (eg, an "inflated" configuration of the fluid container 400).

[0116] In accordance with aspects of the present technology, some pressure sensing algorithms and methods may be used To determine the condition, the foot support bladder 200 and / or the fluid container 400 Sensor inputs in addition to pressure sensing may be relied upon. Examples include accelerometers, foot force sensors, and and / or speed and / or distance monitor, data from the foot support bladder 20 The pressure increase during operation is shown in Figure 2 (using fluid transferred from foot-actuated pumps 600H, 600F). or operational state 5 (transferred from fluid container 400). This can be used to determine whether the fluid should be used to achieve the desired effect. When the user moves relatively slowly, the transfer in operation state 2 is particularly This may be desirable if the user moves quickly and / or When a strong contact force is applied to the foot pump 600H, 600F, the operating state 5 is preferable. Possible (e.g., creating a more uniform fluid flow without pressure spikes due to sole-to-ground contact) Additionally or alternatively, accelerometers, foot force sensors, and / or speed Degree and / or distance monitor data is used to automatically change operating conditions and increasing or decreasing the foot support pressure in the foot support bladder depending on, for example, the speed of movement, the contact force, etc. Further, in addition, or alternatively, at least some systems according to the present technology: And, in an embodiment of the method, the system may determine how the user moves (e.g., specific times of the day). Tendency to run or exercise at a certain time, tendency to run on a certain type of surface, speed "Learning" (e.g., running tendencies, etc.) while changing (e.g., based on a training program) and based on this information, predict changes in operating conditions. , and can be modified to match predicted changes in movement. The pressure changes in the system are better in "real time" and respond to changes in the user's movement. can be synchronized in apparent real time, or linked to a digital coaching system. When linked, automatic (or system-generated) operational state changes are digitally synchronized with desired changes in movement received from the coaching system to achieve desired performance or may mitigate the risk of injury, thereby also improving communication systems with users. It is also a

[0117] Additionally or alternatively, if desired, in accordance with at least some aspects of the present technology The system and method may also be adapted to measure the user's contact force with the ground and / or the user's motion. Sequential metrics about various aspects of the user's running or other Various step metrics, including metrics related to the movement technique(s) Such metrics may be determined and / or used as follows: These may include one or more of: (a) contact time per foot per step (e.g., time added by foot) (b) using a foot force signal, such as a period when the applied normal force is greater than 50 N; swing duration per foot (e.g., when the normal force exerted by the foot is less than 50N) Then, foot force signals such as the time per foot until that foot again produces a force greater than 50N were used to (c) step rhythm (e.g., the reciprocal of the sum of the contact and swing times for each foot, etc.) (d) step length (e.g., sum of contact and swing times × average velocity) (e) impact (e.g., peak velocity of vertical ground reaction force rise, vertical ground (f) foot force signals such as the active peak of the surface reaction force; (f) foot force signals per step. (g) Impulse (e.g., using a foot force signal such as the integral of the magnitude of the ground reaction force at contact); Contact type per foot per step (e.g., foot angle relative to horizontal at foot contact per step, Using motion capture data such as foot contact angle, midfoot contact ankle, and forefoot contact angle).

The specific fluid distributor 500, foot support system, saw If the footwear structure 104 and / or the article of footwear 100 does not include all of the components identified above, (e.g., no separate connector 700, no sealing block 840, one or less footwork) The fluid flow through such components is the fluid flow Not present in the path.

[0124] In operational state 6 shown in FIGS. 5B, 29, and 30G, the valve stem 910 In this sixth rotational position, fluid is drawn from: (a) a fluid supply (e.g., from the external environment 150; Through the connector inlet 702I, through the fluid path 702P, through the connector outlet 702O.

[0125] Thus, as previously mentioned, the valve stem 910 is configured to have multiple openings defined through the peripheral wall 910W. 30B to 30G. As such, rotation of the valve stem 910 causes various specific holes 910H to be sealed by the connector 84. 0 (and / or separate seals) If connector 840 is omitted and / or manifold 800 itself is When functioning as a sealing connector, ports 804, 808, and 814 in the manifold In each operating state of the valve stem 910, the ports 840A, 840B Holes 910H aligned with B, 840C, 804, 808, 814 are circumferentially offset from one another. one required to set, thereby creating the desired fluid flow connections and passages. Only the above holes will align with the correct port. Two (or more) holes through the perimeter wall 910W For operating states that depend on through-hole 910 (e.g., operating states 3, 4, and 5), the fluid flow contact The through holes required to make the connection are: (a) along the axial length and direction of the valve stem 910; and / or (b) may extend parallel through peripheral wall 910W.

[0126] The fluid flow rate into and / or out of the fluid transfer system 900A may vary depending on the species. For example, the periphery of the through hole 910H in the valve stem 910 may be connected to If the connector aligns perfectly with the connected port (e.g., sealing connector ports 840A, 840B, 8 40C), maximum flow rate through holes 910H and aligned ports can be achieved (e.g., fluid depending on the pressure difference between the source direction and the fluid destination direction).

[0127] However, in some applications, maximum flow rate may not be desirable. If the user desires to slightly change the pressure in the foot support bladder 200, a potential overpressure situation can be avoided. This can occur when a fault is approaching, etc. Therefore, if desired, The lube stem 910 is connected to the corresponding connection port (e.g., 840A, 840B, 840C, 804 , 808, 814) so ​​that the through holes 9 10H does not perfectly align with the port to which it is connected. Through-hole connecting ports are used to reduce and control the flow rate and rate of fluid exchange between components. Various implementations of this type of "offset" are possible with respect to the axis of the through hole 910H relative to the 31A-31D show an embodiment in which two through holes 940G, 940H are the two corresponding sealing ports 840B in the above-mentioned operating state 5 of FIG. 30F. , 840C and partially aligned with the two sealing channels 842B, 842C. , these same types of variations may be applied in other operating conditions, and / or where only one through hole should be at least partially aligned with the port, and / or may apply if other through holes are to be at least partially aligned with the ports. The embodiment of Figures 31A-31D includes a sealing connector port 840A that is not aligned with the through hole; and sealing channel 842A (and thus surrounding wall 910W) is shown. and visible through channel 842A).

[0128] In FIG. 31A, the valve stem 910 is rotated and positioned so that the through hole The central axes of 940G and 940H are 10° apart from the central axes of sealing ports 840C and 840B, respectively. offset by degrees of rotation. In at least some configurations (e.g., fluid pressure, hole size) (based on hole size, relative hole size, etc.) The offset is the amount of offset that would occur if the hole and part were perfectly aligned. In FIG. 31B, the valve stem 910 rotates, resulting in a decrease in fluid flow rate of approximately 41% of the total flow rate. As a result, the central axes of the through holes 940G and 940H are aligned with the sealing holes 940G and 940H, respectively. The holes 840C and 840B are offset by 15 degrees of rotation from the central axis of the holes. This results in a reduction in fluid flow of approximately 25% of the total flow rate when the parts are perfectly aligned. The valve stem 910 is rotationally positioned so that the through holes 940G, 940H The central axes are offset by 20 degrees from the central axes of sealing ports 840C and 840B, respectively. This example shows a reduction in fluid flow of approximately 10% of the total flow rate when the hole and part are perfectly aligned. In FIG. 31D, the valve stem 910 is rotated and positioned, so that The central axes of the holes 940G and 940H are aligned from the central axes of the sealing ports 840C and 840B, respectively. The offset is 25 rotational degrees. This example shows the total flow rate when the hole and part are perfectly aligned. In FIG. 31D, only a small portion of holes 940G and 940H are The reduced flow rate may be, for example, due to the increased pressure in the foot support bladder 200 and / or the fluid reservoir 40. For light or slow adjustments, such as fine-tuning the pressure to 0 to the desired pressure, It can be used.

[0129] 32A and 32B show an example manifold 800 (hard plastic) and 8 provides a perspective view and a cross-sectional view of a combined cartridge-style sealing connector 840. As shown, this example manifold 800 has: (a) a surface 800E; Four ports 800A, 800B, 800C, 800D (alignment optional) , (b) fluid inlet port 800I; (c) exemplary aligned ports 804, 808, 8 14 attached to another surface 800F, the first port 804, the second port 808, and the third port (d) port 814 (e.g., the surface opposite surface 800E), and (e) manifold body 820. Four fluid flow paths 802, 806, 810, 812 (optionally aligned and 32A and 32B show opposite sides of manifold body 820. End surfaces 800E, 800F at the manifold body and a straight line from surface 800E to the manifold body Fluid flow paths 806, 810, 812 are shown extending through cavity 820 to surface 800F, but other For example, one of the fluid flow paths 802, 806, 810, 812 may be The above paths may bend and / or bend, resulting in one at one end of the fluid flow path. The above ports 800A, 800B, 800C, 800D correspond to corresponding ports at the other end of the fluid flow path. Ports 800I, 804, 808, and 814 are not located on the opposite surface. Any desired arrangement of and / or path shapes may be used. The arrangements shown are relative This helps maintain the manifold 800 in a relatively compact size and shape.

[0130] In this example, ports 804, 808, and 814 (as well as surface 800F) are manifold The sealing connector 840 is positioned within a recess 800R defined in the body 820. Housed in 800R and chemical adhesive or opposing face seal (and optional The connector 840 of this embodiment is secured by the following: Includes: (a) three ports 800A, 800B, and 800C on one surface 800E; (b) three seals extending from ports 840A, 840B, and 840C to openings in surface 800F; Stop channels 842A, 842B, 842C (openings in the sealing connector on surface 800F) (It may also be considered a "port" of the sealing connector 840.) F abuts the manifold surface 800F and seals channels 842A, 842B, 842 C is aligned with and sealed to the manifold 800 fluid flow paths 806, 810, and 812, respectively. The connector 840 and the manifold 800 are placed in fluid communication. End surfaces 840E, 840F on opposite sides of connector 840 and a seal from surface 840E. Sealing channels 842A, 844B extend straight through the sealing connector 840 to the surface 840F. 2B, 842C are shown, but other arrangements are possible. One or more of the channels 842A, 842B, and 842C may be curved and / or bent. resulting in one or more ports 840A, 840B, 840C at one end of the fluid flow path. are not located on the surface opposite the corresponding opening at the other end of the fluid flow path. Any desired arrangement of openings and / or channel shapes may be used. helps maintain the sealing connector 840 in a relatively compact size and shape.

[0131] The exemplary structure shown in Figures 29-32B has three fluid flow paths in manifold 800. Three sealed channels 842A, 842B, 842C are in fluid communication with the channels 806, 810, 812. 2C. In such a structure, the manifold 80 The fluid inlet path 802 through the nozzle 800 does not pass through the sealing connector 840. Rather, the path The fluid intake path 902A of the housing 900 is directly connected to the fluid intake path 902A of the housing 900 (FIGS. 32A and 32B). Alternatively, as shown in FIG. 32C, the sealing connector 840 may be Four ports 840A, 840B, 840C, 840D and (b) port 840E are provided. Four seals extending from ports 840A, 840B, 840C, and 840D to openings in surface 840F.

Alternatively, if desired, the additional ports in the embodiment of FIG. 32C may be The outlet 840D and sealing channel 842D are used to accommodate separate foot support bladders (if present), separate flow channels, and Fluid passages that are in fluid communication with other components of the overall foot support system, such as the body reservoir (if present). can engage with.

[0132] As discussed above in connection with FIGS. 28A-31G, in some embodiments of the present technology, The stop connector ports 840A, 840B, 840C are formed in the peripheral wall 910 of the valve stem 910. The valve stem 910 moves (e.g., rotates) to directly engage the outer surface of the valve W. An example fluid transfer system 900A is placed in various operating states. Ports 840A, 840B, 840C (and 840D in this example) are characterized and The port maintains a sealed connection between the sealing connector 840 and the valve stem 910 surrounding wall 910W. In the illustrated embodiment, the peripheral wall 91 of the valve stem 910 The outer surface of the 0W has a cylindrical and curved perimeter (e.g., circular perimeter) and cross-sectional shape To maintain good contact and sealing between the sealing connector 840 and the surrounding wall 910W, Even during rotation, the sealed connector ports 840A, 840B, 840C (and 840 D) has an arched outer surface configuration (840S).

This offers several advantages in that they are generally less susceptible to breakdown by other undesirable substances. Optical encoders may, for example, mask or block the light source or the light detecting elements. The magnetic encoder system 930 and the magnetic encoder system 930 are more susceptible to failure due to undesirable materials. Other position sensor systems are known and commercially available.

C. Characteristics of Solenoid-Based Fluid Transfer Systems

[0150] The fluid transfer system 900A utilizes a movable (e.g., rotatable) valve stem 910. The stem is movable to various positions and functions as a fluid distributor 500, a fluid flow restrictor, and a fluid flow control valve. The control system, foot support system, sole structure 104, and / or article of footwear 100 may be However, other types of fluid transfer systems 900 may be placed in one or more operating states. Such systems and components may be configured in any two or more of the operating states described above with respect to FIGS. 5A-5F. The following discussion applies to the present technology. In accordance with at least some aspects of the present invention, a solenoid-based fluid transfer system 900B Regarding.

[0151] Various types of solenoids and / or combinations of solenoids are possible in some of the present techniques. 900B according to some embodiments. Some solenoids are "latching solenoids." Some latching solenoids, such as the 4200, have an open and closed state. Such a solenoid has two stable states: Figure 42 shows the solenoid 4200 in an open state. In this state, the plunger 4202 moves backward, causing the fluid to flow through one port 420 Through the solenoid body 4204 (in either direction) between port 6 and the other port 4208 See fluid flow arrow 4212. In the closed state, spring 4210 or other biasing means urges plunger 4202 forward to open ports 4206, 4208. In this state, the fluid flows through the solenoid body 420. It does not flow through 4.

[0152] The latching solenoid starts the movement of the plunger 4204 and A force is required to change the solenoid 4200 from one state to another. A pulse of force is applied to move plunger 4202 of solenoid 4200 from one position to another. Latching solenoids also generally have a "steady state." The "normal state" is when a "latch" is created to hold the plunger 4200 in one of several states. If not activated, the default is plunger 4200 (e.g., plunger 4204 (due to the above bias).

[0153] For bidirectional latching solenoids, the solenoid is designed to allow fluid to flow through the solenoid. "Normally Open" ("NO"), where fluid cannot flow through the solenoid, or "Normally Open" ("NO"), where fluid cannot flow through the solenoid. Force can be applied to a normally open solenoid in relatively short pulses. (a) moving the plunger from an open configuration to a closed configuration; and (b) a latching mechanism. This activates the solenoid to hold it in the closed position without the continuous application of force. To return the knob to the open configuration, a force is applied to unlatch it or to activate it with a relatively short pulse. The plunger is "unlatched" and then a biasing system (e.g., a spring) opens the plunger. Back to the basics. A "normally closed" solenoid works in a somewhat opposite way. The force is relatively short. A pulse can be applied to a normally closed solenoid to: (a) move the plunger from a closed configuration to an open configuration; and (b) actuate the latching mechanism to release the solenoid without the continuous application of force. The solenoid is held in the open position. A force is applied to return the solenoid to the closed configuration. Release the switch or "unlatch" the plunger with a relatively short pulse and then energize A system (e.g., a spring) returns the plunger to the closed configuration, thus latching between different configurations. A relatively small amount of force is consumed to move the moving solenoid, and the force is not applied continuously for a long period of time. Because of the position of spring 4210 in FIG. 42, the illustrated solenoid 4200 is a "normally closed" solenoid. Spring 4210 moves port 4206 and plunger 4 When a biasing force is applied between the front surface 4202S (area A) of 202, the solenoid is "normally It would be "open".

[0154] Like latching solenoids, non-latching solenoids also have one "normal" position. (e.g., NO or NC) and may have one (or more) non-stationary positions Unlike latching solenoids, non-latching solenoids are used to connect two (or more) valves. A continuous force must be applied to maintain the material in one of two states (or more). Normally open ("NO") non-latching valves move and maintain the valve in a closed state. A continuous force must be applied to maintain the device, but if the force is shut down ( For example, under a biasing force applied to the plunger), it returns to an open state. "NC") valves require continuous force to move and maintain the valve in the open state. If necessary, but the force is shut down (for example, if the force is applied to the plunger This reduces power consumption and / or battery life during use. From the viewpoint of battery life, a normally open non-latch valve is recommended for applications where the valve only needs to be closed for a relatively short period of time. It may be beneficial to select a switching solenoid and / or a relatively short-term valve. It is beneficial to select a normally closed non-latching solenoid for applications where the valve only needs to be open. It could be.

Thus, the first port 4310A, 431 2A, 4314A can be aligned at one end of the fluid transfer system 900B, and all ports This type of "single-sided" arrangement is, for example, 00 and / or sole structure 104. obtain.

[0162] 48A-48F show the six operating states described above in connection with FIGS. 5A-5F. FIG. 48 provides a schematic diagram of one exemplary solenoid-based fluid transfer system 900B. FIG. 5A (together with FIG. 5A) shows one operating state in which the fluid is in contact with the external environment 150 from the outside, into the fluid distributor 500, and is expelled back to the outside environment 150. Fluid flow in this operating state is shown by dashed lines with thick arrows in Figures 5A and 48A. This operating state occurs when a pressure change to the foot support bladder 200 and / or fluid reservoir 400 occurs. Even if not required, fluid is pumped through the fluid distributor 500. It can be used as a "standby" or "steady state" operating condition, allowing the flow of fluid to continue. In this operating state, the incoming fluid from the external environment 150 (e.g., the atmosphere) is, for example, As previously described with respect to FIG. 5A, the fluid transfer system In this first operating state, the first solenoid 4300A is open. configuration, the second solenoid 4300B is in the closed configuration, and the third solenoid 4300 C is in a closed configuration. This allows the fluid to flow from the source (e.g., pumps 600H, 600F, from the manifold port 800A through common fluid line 4320. , through fluid line 4310F to first port 4310A of first solenoid 4300A. through the first solenoid 4300A to the second port 4 of the first solenoid 4300A. 310B, through manifold port 800B, and to its final destination (this In the example, the external environment 150).

[0163] Alternatively, in some embodiments of the present technology, the fluid is simply expelled in this operating state. If the fluid is to be returned to the external environment 150, the fluid distributor 500 Instead of continuously moving fluid through the pump(s) 600H, 600F, A fluid path could be provided that drains directly from the vent into the external environment 150. As a result, pump(s) 600H, 600F are stopped to give this operating state. obtain.

[0164] FIG. 48B (together with FIG. 5B) shows one operating state in which the fluid The fluid moves from the boundary 150 into the fluid distributor 500 and into the foot support bladder 200. Fluid flow in this operating state is indicated by dashed lines with thick arrows in Figures 5B and 48B. This operating state may be used, for example, for a more stable feel and / or Increased pressure in the Leg Support Bladder 200 to support strenuous activities (e.g. running) In this operating state, the external environment 150 (e.g., the atmosphere) The inlet fluid travels through manifold 8, as described above with respect to FIGS. 5A and 5B, for example. 00 and reaches the fluid transfer system 900B. , the first solenoid 4300A is in a closed configuration and the second solenoid 4300B is in an open configuration. , and the third solenoid 4300C is in a closed configuration. This allows the fluid to flow from the source (e.g., Pump 600H, 600F, compressor, etc.) through manifold port 800A. Through the fluid line 4320, through the fluid line 4310F, the second solenoid 430 through the first port 4312A of the solenoid 4300B, through the second solenoid 4300B, through the second port 4312B of the manifold 4300B, through the manifold port 800C, and flows to its final destination (in this example, the foot support bladder 200).

[0165] In some applications, the foot support bladder 200 may be configured to reduce pressure in the foot support bladder. It may be desirable to remove fluid from the ladder 200 (e.g., to provide a softer feel, or for less strenuous activities such as walking or casual wear). Figure 48 FIG. 5C (together with FIG. 5C) shows an example of this operating state. The flow is shown by the dashed line with thick arrows in Figures 5C and 48C. In this third operating state, Thus, the first solenoid 4300A is in an open configuration and the second solenoid 4300B is in an open configuration. and third solenoid 4300C is in a closed configuration, which allows fluid to flow through the foot support bladder. 200 through the second manifold port 800C to the second port of the second solenoid 4300B. through port 4312B, through second solenoid 4300B, and to the first port of the second solenoid. through port 4312A, through fluid line 4312F, through common fluid line 4320 4300A。 4300B through the fluid line 4310F.

(in this example, the external environment 150).

[0166] In accordance with some embodiments of the present technology, a fluid transfer system 900B and a foot support system Another possible operating state for is shown in Figure 48D (together with Figure 5D). In this case, the fluid is, for example, reduced in fluid pressure in fluid container 400, so that the fluid 5D and 48D. In this fourth operating state, the first solenoid 4300A is is in an open configuration, the second solenoid 4300B is in a closed configuration, and the third solenoid 43 00C is in an open configuration, which allows fluid to pass from the fluid reservoir 400 to the third manifold port 800D, through the second port 4314B of the third solenoid 4300C, through the first port 4314A of the third solenoid 4300C. , through fluid line 4314F, through common fluid line 4320, and through fluid line 431 0F, through the first port 4310A of the first solenoid 4300A, through the second port 4310B of the first solenoid 4300A, through manifold port 800B and to its final destination (in this example, the external environment 150).

[0167] In accordance with aspects of the present technology, some of the fluid transfer system 900B and foot support system In one embodiment, an on-board fluid reservoir 400 is used to regulate pressure in the foot support bladder 200. It may be desirable to adjust (and in this example increase) the operating state. One embodiment is shown in FIG. 48E (together with FIG. 5E). In this fifth operating state, the first The first solenoid 4300A is in a closed configuration, the second solenoid 4300B is in an open configuration, and the third solenoid 4300C is in a closed configuration. 3 solenoid 4300C is in the open configuration, which allows pressure in the fluid reservoir 400 to If the pressure in the manifold 200 is higher than the pressure in the fluid reservoir 400, the fluid flows from the fluid reservoir 400 to the third manifold port 80. 0D, through the second port 4314B of the third solenoid 4300C, The flow passes through the first port 4314A of the third solenoid 4300C. through body line 4314F, through common fluid line 4320, and through fluid line 4312F through the first port 4312A of the second solenoid 4300B, 4300B, through the second port 4312B of the second solenoid 4300B, It flows through hold port 800C and to its final destination (in this example, a foot support bladder). 200).

[0168] FIG. 48F (together with FIG. 5F) illustrates an exemplary operating condition for adding fluid to the fluid container 400. (e.g., to increase the volume and / or pressure of fluid in fluid container 400) In this sixth operational state, the first solenoid 4300A is in a closed configuration and the second solenoid The third solenoid 4300B is in a closed configuration, and the third solenoid 4300C is in an open configuration. This allows fluid to flow from the source (e.g., pump 600H, 600F, compressor, etc.) to the manifold. through common fluid line 4320, through fluid line 4314F. Then, the voltage flows through the first port 4314A of the third solenoid 4300C to the third solenoid 43 00C, through the second port 4314B of the third solenoid 4300C, through the fluid port 800D and to its final destination (in this example, the fluid container 400). .

[0169] As previously described, in accordance with some embodiments of the present technology, the fluid distributor 500 Body Flow Control System, Foot Support System, Sole Structure 104, and / or Footwear Article 100 It is not necessary for the present technology to provide all six of the aforementioned operating states. In some embodiments, more, fewer, and / or different operating states may be utilized. 49A-49D show one leg support bladder 200 and one fluid volume. An exemplary solenoid-based fluid transfer system having four operating states when the device 400 is present. A system 900C is illustrated.

[0170] This example fluid transfer system 900C includes two solenoids: (a) first port 4 a first solenoid 4910A, a second port 4910B, and a third port 4910C; 900A; (b) a second solenoid 4 including a first port 4912A and a second port 4912B; 900B. In this example fluid transfer system 900C, solenoids 4900A, 490 First ports 4910A and 4912A of 0B are each in fluid communication with a common fluid line 4920. For this reason, the common fluid line 4920 also connects the solenoids 4900A, 4900B The first ports 4910A, 4912A are disposed in fluid communication with each other (at least some As an example, the common fluid line 4920 may branch into: ) fluid line 4910F (leading to first port 4910A of first solenoid 4900A); and (b) fluid line 4912F (first port 4912A of second solenoid 4900B) In addition, common fluid line 4920 also includes, for example, a manifold 800 port. one of the fluid inlet 800A, the fluid inlet path 802, the fluid inlet port 800I, the connector 700, etc. a fluid source (e.g., pump(s) 600H, 600F, compressor) through one or more , the external environment 150, etc.). The 4900A can be a latching 3-port, 2-state solenoid (3 / 2 solenoid), and the second solenoid 4900B is a normally closed non-latching solenoid (2 / 2 solenoid The solenoid may be a valve or valve spring, although other specific types of solenoids may be used if desired. The system 900C may, for example, be a manifold 800 of the various types described above (e.g., a 4-port and a four-fluid path manifold).

[0171] In this illustrated embodiment (and described in more detail below), the first solenoid The ports 4900A are individually switchable to: (a) connect the fluid to the first port 4910A and the second port 4910B; (b) a first configuration passing through the first solenoid 4900A between the ports 4910B; and (c) a second configuration passing through the first solenoid 4900A between the ports 4910B. Fluid flows through the first solenoid 4900A between the first port 4910A and the third port 4910C. This is the second configuration in which the first port 4910A and the first Solenoid 4900A remains open at all times, and plunger 4910P moves between: Move: (a) the second port 4910B is open, and the third port 4910C is closed; 1 position, and (b) the second port 4910B is closed and the third port 4910C is open. In the illustrated embodiment, the first solenoid 4900A is in the "normal" position. The bias system is biased to be in the first configuration (closing the third port 4910C). In this example, the second solenoid 4900B is in an open configuration (fluid is directed through the first port 4912). A and second port 4912B) and a closed configuration (fluid flows through solenoid 4900B This fluid transfer can be individually switched between ON and OFF (no fluid flows through solenoid 4900B). In the fluid transfer system 900C, the following simultaneous optional installations are performed: C selectively placed into a plurality of (e.g., two or more) operating states: (a) a first configuration or a second configuration; and (b) a first solenoid 4900A in one of two configurations, and (b) an open configuration or a closed configuration. The second solenoid 4900B is in one of the configurations. Examples are described in more detail below.

[0172] 49A-49D show a solenoid-based fluid transfer system that can be placed in four operating states. FIG. 49A (together with FIG. 5A) shows one operating state, and this operation In operation, fluid moves from the external environment 150 into the fluid distributor 500. , and is discharged back to the external environment 150. The fluid flow in this operating state is shown in FIG. This operating state is indicated by the dashed line with the thick arrow in Figure 49A. and / or fluid distribution even if a pressure change to the fluid container 400 is not required. A "standby" or "standby" mode is used to keep the pumped fluid moving through the computer 500. In this operating state, the external environment 150 ( Incoming fluid from, for example, the atmosphere, travels to a manifold, as described above with respect to FIG. 5A. In this first operating state, the fluid passes through the field 800 and reaches the fluid transfer system 900C. , the first solenoid 4900A is in a first configuration, and the second solenoid 4900 B is in a closed configuration, which allows fluid to flow from the source (e.g., pumps 600H, 600F, compressor, etc.) through manifold port 800A and common fluid line 4920. 4910F to the first port 4910 of the first solenoid 4900A. A through the first solenoid 4900A, and the second pole of the first solenoid 4900A. through port 4910B, through manifold port 800B, and to its final destination. (in this example, the external environment 150).

[0173] Alternatively, in some embodiments of the present technology, the fluid is simply expelled in this operating state. If the fluid is to be returned to the external environment 150, the fluid distributor 500 Instead of continuously moving fluid through the pump(s) 600H, 600F, A fluid path could be provided that drains directly from the vent into the external environment 150. As an example, pump(s) 600H, 600F must be stopped to achieve this operating state. possible.

[0174] FIG. 49B (together with FIG. 5F) illustrates an exemplary operating condition for adding fluid to the fluid container 400. (For example, to increase the volume and / or pressure of fluid in fluid container 400). In this second operating state, the first solenoid 4900A is in a second configuration, and the second solenoid The solenoid 4900B is in a closed configuration, which allows fluid to flow from the source (e.g., pump 60) 0H, 600F, compressor, etc.) through manifold port 800A to the common fluid line. Through the inlet 4920, through the fluid line 4910F, the first solenoid 4900A 1 through port 4910A, through first solenoid 4900A, and through first solenoid 49 through the third port 4910C of 00A, through manifold port 800D, and finally It flows to its final destination (in this example, fluid container 400).

[0175] In this exemplary fluid transfer system 900C, the on-board fluid reservoir 400 is a foot-supported It is used to adjust (and in this example increase) the fluid pressure in the bladder 200. One example of this operating state is shown in Figure 49C (together with Figure 5E). , the first solenoid 4900A is in the second configuration, and the second solenoid 4900 B is in the open configuration, which allows the pressure in the fluid reservoir 400 to be higher than the pressure in the foot support bladder 200. If not, the fluid flows from the fluid container 400 through the third manifold port 800D to the first through the third port 4910C of the solenoid 4900A, and through the first solenoid 4900A. , through a first port 4910A of a first solenoid 4900A, and a fluid line 4910F. through common fluid line 4920, through fluid line 4912F, to the second solenoid through a first port 4912A of the solenoid 4900B, through a second port 4912B of the solenoid 4900B, through the second port 4912B of the second solenoid 4900B to the manifold port 800 C and to its final destination (in this example, the foot support bladder 200).

[0176] In some applications, the foot support bladder 200 may be configured to reduce pressure in the foot support bladder. It may be desirable to remove fluid from the ladder 200 (e.g., to provide a softer feel, or for less strenuous activities such as walking or casual wear). Figure 49 Figure 5D (together with Figure 5C) shows an example of this operating state. In this operating state, the fluid flow is In this fourth operating state, the first solenoid 4900A is is in the first configuration and the second solenoid 4900B is in the open configuration. , from the foot support bladder 200 through the second manifold port 800C to the second solenoid 49 The second solenoid 4900B is connected to the second port 4912B of the Through a first port 4912B of the fluid line 4912F, Through fluid line 4920, through fluid line 4910F, the first solenoid 490 0A through the first port 4910A, through the first solenoid 4900A, through the second port 4910B of the manifold 4900A, through the manifold port 800B, and flows to its final destination (in this example, the external environment 150).

[0177] This allows the fluid transfer system 900C to have a higher fluid transfer efficiency than the fluid transfer system 900B. Transmission system 900B includes four or fewer operating states rather than the six operating states previously discussed. Specifically, the fluid transfer system 900C of FIGS. 49A-49D does not have one operating state; In this state, fluid moves from the external environment 150 into the fluid distributor 500, and and directly into the foot support bladder 200 (as shown in Figures 5B and 48B). In fact, in the fluid transfer system 900C of FIGS. 49A to 49D, the fluid pressure is The amount of fluid that increases in the foot support bladder 200 is solely due to fluid transfer from the 400 to the foot support bladder 200. (shown in an operational state in FIG. 49C). System 900C does not have one operating state in which fluid is pumped from fluid container 400 to Move to external environment 150 (as shown in Figures 5D and 48D). If desired, the fluid container 400 may include a check valve that is open to the outside environment. Prevents overpressurization of fluid container 400 (excess fluid from fluid container 400 is transferred to the fluid transfer system) 900C to reduce the pressure in the fluid container 400). Alternatively, fluid pressure from a fluid source (e.g., one or more foot-actuated pumps 600H, 600F) (fluid pressure generated by) is insufficient or open fluid to the fluid container 400 Below the fluid pressure in the passageway, fluid will not move from the source to the fluid container 400. In addition to or alternatively, other pressure reducing valves and / or fluid passages may be provided in the fluid transfer system 900. C. Fluid distributor 500, fluid flow control system, foot support system, sole structure Any of the system may be attached to one or more locations throughout the body 104 and / or article of footwear 100. This may be provided to prevent overpressurization of the pump if there is no other place for the fluid to flow. (Several) 600H, 600F release pressure from the fluid expelled).

[0178] However, the fluid transfer system 900C has three This has several advantages in that it uses only two solenoids. The stem 900C is somewhat lighter, smaller, and less expensive than the fluid transfer system 900B. , and / or may be more energy efficient (e.g., consume less battery power). .

[0179] The aforementioned fluid transfer systems 900B and 900C are configured with one foot support bladder 200 and one However, if desired, at least some aspects of the present technology may include a fluid container 400. Therefore, the fluid transfer system, foot support system, fluid distributor 500, sole structure The structure 104, and / or the article of footwear 100, may include a structure for supporting fluid pressure changes. More than one foot support bladder 200 and / or more than one fluid reservoir 400 may be included. If more than one foot support bladders 200 are present, fluid may be introduced into all bladders simultaneously. This can be accomplished in a variety of ways. For example, all foot support bladders are fluid-lined. branching the bladder 202 into individual foot support supply lines leading to corresponding individual foot support bladders; As another example, all of the foot support bladders in footwear article 100 may be filled with The support bladders can be filled simultaneously by fluid lines connecting them in series or in parallel. More than one fluid container 400 may be filled simultaneously in the same manner, but it is not necessary to fill the container fluid line. branching the pipe 402 into individual lines and / or connecting fluid containers in series or parallel By doing so.

[0180] Multiple foot support bladders 200 and / or fluid containers 400 are present in a single shoe 100; Possibly providing different fluid pressures in the bladder 200 and / or connector 400 For example, if desired, fluid may be directed away from the container 700 and into the foot support fluid line 20. 2 and / or the reservoir fluid line 402, appropriate valving or switching mechanisms may be used to Alternatively, if desired, the connector 700, manifold 800, and and a separate fluid passageway through sealing connector 840 (if present) for each individual foot support. A separate solenoid may be provided for the bladder 200 and / or the fluid container 400; may be provided for additional foot support bladders 200 and / or fluid reservoirs 400; and Additional operating states may be provided. In other words, fluid may be pumped into and out of the foot support bladder 200. To achieve this, the addition of ports, fluid channels, solenoids, and the like is required, as shown. An additional set may be provided for each additional foot support bladder and / or fluid may be added to the fluid container 4. To get into or out of the 00, use the ports, fluid channels, solenoids, and Additional sets of the same may be provided for each additional fluid reservoir in the shoe. system (e.g., on an external computing device, as part of an "on-board" switching system 2200, etc.) Also, separate inputs and controls are available for each additional foot support bladder and / or fluid container. It can be modified to make it possible

[0181] 49A-49D show an ("optional") second embodiment of fluid transfer system 900C. A schematic diagram of a bipedal support bladder 250 is shown, which allows this fluid transfer system 900C a third solenoid 4900 for moving fluid in and out of the second foot support bladder 250; The third solenoid 4900C has a first port 4914A and a second port 4914B. The solenoid is always on, e.g., a 2 / 2 solenoid. The first port of the third solenoid 4900C may be configured as a closed non-latching solenoid. Port 4914A may have fluid line 4914F in fluid communication with common fluid line 4920. The second port 4914B of the third solenoid 4900C is connected to the second leg support bladder 250. The fluid may be in fluid communication with the foot support bladder 2 from the second port 4914B in any desired manner. 50 includes ports and fluid paths through manifold 800, sealing connector 840 (if present), connector 700 (if present), etc., The path is generally similar in structure and / or function to the second port 44 of the second solenoid 4900B. 912B and the foot support bladder 200.

[0182] The fluid transfer system 900C of FIGS. 49A-49D includes a first solenoid 4900A and The second solenoid 4900B is placed in the configuration shown in FIGS. 49A-49D, and the third solenoid By maintaining the spheroid 4900C in a closed configuration, all of the movements shown in Figures 49A-49D are However, this exemplary fluid transfer system 900C must adjust for the following: Two additional operating states may be included: (a) increasing fluid pressure in the second foot support bladder 250; and (b) a decrease in fluid pressure in second leg support bladder 250. A fifth operating state, used to increase the fluid pressure in 50, is solenoid 4900A, a second solenoid 4900B in the closed configuration, and a 49C. In the method, fluid passes from the fluid container 400 through the third manifold port 800D to the third manifold port 800C. 1 solenoid 4900A through the third port 4910C of solenoid 4900A. through a first port 4910A of the first solenoid 4900A to the fluid line 491 0F, through common fluid line 4920, through fluid line 4914F, Through the first port 4914A of the solenoid 4900C, through the third solenoid 4900C and then through the second port 4914B of the third solenoid 4900B to the final destination. The fluid flows to the target area (in this embodiment, the foot support bladder 250).

[0183] Similarly, a sixth action is used to reduce the fluid pressure in the second leg support bladder 250. The states are: first solenoid 4900A in a first configuration, second solenoid 4900B in a closed configuration, 900B, and a third solenoid 4900C in the open configuration. In a manner similar to the configuration shown in 9D, fluid is pumped from the foot support bladder 250 (or any (Even if a fluid passage is provided) through the second port 4914B of the third solenoid 4900C. , through the third solenoid 4900C, to the first port 4914 of the third solenoid 4900C. A, through fluid line 4914F, through common fluid line 4920, through the first port 4910A of the first solenoid 4900A, Through the first solenoid 4900A, the second port 4910B of the first solenoid 4900A through manifold port 800B and to its final destination (in this example is the external environment 150).

[0184] Additional solenoids (e.g., 2 / 2 non-latching solenoids) and appropriate structural and mechanical Operational conditions may be provided for any additional leg support bladders 200 and 250 described above.

[0185] As described in this disclosure, aspects of the present technology include one or more leg support bladders 200, and / or or one or more fluid reservoirs 400 (a reservoir may also be a fluid-filled bladder). However, the various examples described above relate to controlling and varying the pressure in the footwear components. In the illustrated structure, pressure sensors (e.g., 850A, 850B) are connected to corresponding foot support brackets. directly within or engaged with the nozzle 200 and / or fluid container 400. Pressure sensor(s) 850A, 850B for type 200 foot support bladder and / or directly in or with the fluid container 400 , for example, due to the flexible bladder structure, due to its location within the footwear, and due to the difficulty of assembling the footwear. For this reason, as described above, the system and method In accordance with at least some embodiments of the technology, a manifold 800 or sealing connector 8 Pressure sensor(s) 850A, 85B, 85C, 85D, 85E, 85F, 85G, 85H, 85I, 85N, 85NQ ... Such fluid lines then connect the foot support bladders 200 and / or the fluid In this manner, the pressure sensor(s) 850A, 850B are in fluid communication with the vessel 400. A fluid distributor 500 (as described above) may be provided, and a fluid distribution Since the footwear 100 is connected to the footwear 500, it is easier and more convenient to construct the footwear 100. can be incorporated into the whole.

[0186] If fluid does not flow through the appropriate fluid line equipped with sensor 850A, 850B, In this case, such sensors 850A, 850B are generally located in the foot support bladder 200 and / or accurately measure the pressure in the fluid container 400 (because sensors 850A, 850B The foot support bladder 200 and / or fluid container 400 are attached to a fluid line in open fluid communication with the foot support bladder 200 and / or fluid container 400. However, the pressure sensor(s) 850A and 850B are attached to the foot support brake. manifold 8 for not being directly contained in ladder 200 and / or fluid container 400 00 or pressure sensor(s) 850A, 850B in the sealing connector 840 The pressure readings obtained will be used to measure the pressure in the foot support bladder 20 when fluid is flowing through the appropriate fluid line. 0 and / or may not correspond to the actual pressure present in the fluid enclosure 400. Therefore, the fluid flowing through the manifold 800 and / or sealing connector 840 may be significantly There may be significant flow restrictions because the fluid is The fluid flows through relatively small fluid lines (e.g., small cross-sectional area and diameter) within the rotor 840. This flow resistance at the locations of pressure sensors 850A and 850B is 0 and / or the actual pressure in the fluid container 400 compared to sensors 850A, 850B of the pressure obtained at (and at manifold 800 and / or sealing connector 840) This "difference" between the sensed pressure and the actual pressure is called the "offset." During fluid flow, this flow resistance offset may also be referred to as the pressure sensor 850A. , can be affected by the flow rate through 850B (i.e., flow rate dependent offset). Resistance offset also significantly alters the start, stop, and / or flow rate of fluid. It may be more noticeable immediately afterwards.

[0187] For this reason, systems and methods, in accordance with at least some aspects of the present technology, are and pressure sensor(s) within manifold 800 and / or sealing connector 840. Determine the "adjust" pressure based on the pressure reading taken by the pressure sensor (e.g., 850A, 850B). Such adjusted pressure(s) may then be used to determine when to start and stop fluid flow. inputs that determine the flow (e.g., the microprocessor of the on-board fluid distributor 500) used as input data for the external processor that controls the pressure change operation, etc. (e.g., timing of rotation of valve stem 910 and / or foot support) One or more solenoids may be used to regulate the pressure in the bladder 200 and / or fluid container 400. When to change the configuration of the ID (e.g., 4300A~4300C, 4900A~4900C) The use of regulating pressure(s) to control pressure change regulates fluid flow in response to pressure change input. This may allow the control system to better reach the target pressure. For example, sensor 8 The use of regulated pressure as opposed to directly using the measured pressure of the 50A and 850B is In the bladder 200 and / or fluid container 400, pressure sensors 850A, 850 B) the system and / or method is more direct and / or The pressure change "overshoot" or "undershoot" will be minimized to reach the desired pressure. Additionally or alternatively, the system and / or method may A few cycles of "starting" and "stopping" the fluid flow to reach the final target pressure (approx. and especially for fine tuning and adjusting the pressure in short bursts with little initial pressure to reach the final target pressure. (for example, by using a pressure regulator) may allow the target pressure to be reached.

[0188] In some embodiments of this aspect of the present technology, the adjusted pressure due to the flow offset is The state observer model can be used to determine the system state. , the system is the actual system (in this example, the foot support bladder 200 and / or The actual pressure in the fluid vessel 400, P ACTUAL ) measured value (in this example, the manifold Pressure sensors 850A, 850B at the pressure sensor 800 and / or the sealing connector 840 Force measurements, (P 850A、850B ) for the internal state of the actual system given by Figures 50A and 50B illustrate one possible state observer model. To provide a helpful illustration, Figure 50A shows the electrical layout of a pneumatic control system of the type described herein. The actual system shown is the air-equivalent model 5000. The model includes a cushion 200 ("cushion") and one fluid container 400 ("tank"). In this example, the fluid container 400 and foot support bladder 200 act as a capacitor and a reservoir pressure. Fluid flow through various system components is modeled as resistors (e.g. The fluid flow between the fluid container 400 and the fluid transfer system 900 is shown as register 5020. 5022, and the fluid flow through the fluid transfer system 900 is shown as a register 5022 and a foot support. The fluid flow between the retainer bladder 200 and the fluid transfer system 900 is shown as resistor 5024. (This is the case.)

[0189] FIG. 50B shows how the state observer model 5000 of FIG. 50A compares the actual sensor 85 0A, 850B correspond to or illustrate the pressure measurements (and other relevant information) in 850B. Line 5 002 represents the desired target pressure in the foot support bladder 200, and just before time 358.5 5004 and 5006 show the desired pressure change from about 18 psi to about 27 psi. represent the operation of the solenoid valves for the fluid container 400 and the foot support bladder 200, respectively. Such lines 5004 and 5006 are connected to each other when the desired pressure change is triggered. This indicates that one solenoid valve changed configuration (shortly before time 358.5). The change in configuration configures the solenoid to allow fluid to be transferred from the fluid reservoir 400 to the foot support bladder 200. allowing the foot support bladder 200 to move (thereby increasing pressure in the foot support bladder 200); and (This reduces the pressure in the fluid container 400.) Curve 5008 is in fluid communication with the fluid container 400. The measured values ​​obtained by sensor 850A in the manifold / sealed connector fluid line The curve 5010 shows the pressure measurements at the time of the foot support bladder 200. Actual pressure acquired by sensor 850B in the hold / seal connector fluid line As is evident from curves 5008 and 5010, the actual sensor 850A , 850B measurements are taken when flow starts and stops due to flow resistance offset. This flow resistance offset generally decreases as the cross-sectional area of ​​the fluid line decreases. becomes even more pronounced.

[0190] On the other hand, curves 5012 and 5014 are predicted by model 5000 of FIG. 50A. As shown, such curves 5012 and 5014 are quite There is no "jumping" and therefore no fluid reservoir 400 and / or foot support bladder 2 00. Pressure sensor 850A, and / or 85 From the actual measured pressure reading at 0B, the pressure value of the state observer is calculated as 0. For example, pressure sensor measurements 850A, 850B (this measurement The set value is based on the voltage measured by the sensors 850A and 850B. and various resistors 5020, 5022, 5024 and capacitors in the model 5000. Considering the known values ​​assigned to the resistance (tank and cushion), the fluid vessel model The voltage at location 5026 of the foot support bladder model and location 5028 of the foot support bladder model can be calculated. The calculated voltage corresponds to the calculated state observer pressure value.

[0191] These calculated state observer pressure values ​​are then applied to the foot support bladders 200 and / or or may be used as an input corresponding to the pressure in the fluid container 400. Pressure Input and Data The use of the calculated state observer pressure value as , systems and / or methods may be more direct and / or "overshoot" the pressure change. "Overshoot" (e.g., over-inflating) or "undershoot" (e.g., under-dragging) Allows the desired pressure to be reached more quickly and / or reduces the number of "start" and "stop" cycles. This allows the target pressure to be reached quickly (e.g., due to the absence of "jumps").

[0192] Actual pressure readings from pressure sensors 850A and 850B are used to determine the adjusted pressure value (and assuming actual pressure in the foot support bladder 200 and / or fluid container 400) Other methods of determining the foot support pressure may be used. 200, fluid line 400, fluid distributor 500 components, A laboratory physical model of the entire stem can be created, but this model also includes the foot support bracket. The ladder 200 and fluid container 400 may include pressure sensors to measure the actual pressure in such components. Then, using this physical model, the pressure measurements can be calculated as follows: (a) the manifold 800 and / or the sealing connector 84; Pressure sensor(s) 850A, 850B located at 0 (P 850A、850B ), and (b) various operating conditions (e.g., using different flow rates, using different starting pressures, The foot support bladder 200 and / or or by additional pressure sensor(s) included in the fluid container 400 (P ACTUAL ). By comparing the actual pressure readings in part (a) with the values ​​in part (b), the difference in actual measured pressure is may be used to develop correction factors for use in systems and methods In the method, the actual pressure measurement is taken from the manifold 800 and / or the sealing connector 84. 0 (i.e., additional pressure sensor(s) are available in the foot support bladder 20 0 and / or in an actual shoe in use that is not included in the fluid container 400). The correction factor is , lookup table, formula i.e. P 850A、850B P ACTUAL Convert to P equation, "best fit" curve, etc. 850A、850B and microphone The pressure readings can be applied to the manifold 800 and / or or pressure sensor reading (P 850A、850B ) suitable for the conditions Applying a correction factor gives an adjusted pressure value, which can be used as an example, as described above. It can be used as an input to control the pressure change. III. Conclusion
