[0003] The present invention relates to fluid flow control systems and / or foot support systems in the field of footwear or other foot receiving devices. At least some aspects of the present invention relate to fluid distributors, fluid transfer systems, sole structures, fluid flow control systems, foot support systems, footwear , and / or other foot receiving devices, and other foot receiving devices include components (e.g., manifolds, fluid transfer systems, electronic control devices, etc.) for selectively moving fluid within, into, and / or out of a sole structure (or other foot support member) and / or footwear (or other foot receiving device). By using such systems, the fluid pressure (e.g., foot support pressure, fluid container pressure) within one or more fluid-filled bladders (e.g., foot support bladder(s)), and / or one or more fluid reservoirs and / or fluid containers included throughout the system can be varied and controlled. BACKGROUND OF THE INVENTION

[0004] Conventional athletic footwear includes two main elements: an upper and a sole structure. The upper can provide a foot cover that securely receives and positions the foot relative to the sole structure. Furthermore, the upper can have a configuration that protects the foot and provides ventilation to cool the foot and remove sweat. The sole structure can be fixed to the lower surface of the upper and is generally disposed between the foot and an arbitrary contact surface. The sole structure can provide traction and control against harmful foot movements such as pronation, in addition to attenuating ground reaction forces and absorbing energy. ​

[0005] The upper forms a void inside the footwear for receiving the foot. This void has the shape of a typical foot and access to the void is provided at the ankle opening. Thus, the upper extends along the inner and outer sides of the foot, around the heel region of the foot, over the instep and toe tip regions of the foot. The upper often incorporates a lacing system to allow the user to selectively size the ankle opening and, in particular, to partially change the circumference of the upper to accommodate various proportions of the foot. In addition, the upper may include a tab that extends under the lacing system and may include (e.g., to adjust the pressure applied to the foot by the shoelaces) to improve the comfort of the footwear. The upper may also include a heel counter that restricts or controls heel movement.

As shown, this exemplary foot support system includes a fluid-filled foot support bladder 200 for supporting at least the front foot portion of the user's foot. A portion of the fluid container 400 (and also the fluid-filled bladder) of this embodiment is positioned directly below the foot support bladder 200 and extends rearwardly beyond the rear edge of the foot support bladder (see also FIG. 1). The upper sole component 104U (e.g., an upper midsole component formed of a polymeric foam material as an option) overlaps and / or engages the foot support bladder 200. The lower sole component 104L (e.g., a lower midsole component formed of a polymeric foam material as an option) overlaps and / or engages the foot support bladder 200. In this illustrated embodiment, both the upper sole component 104U and the lower sole component 104L extend rearwardly and each includes at least a plantar support surface 104US, 104LS in the heel support region of the sole structure 104. Also, in this illustrated embodiment, both the upper sole component 104U and the lower sole component 104L include openings 104UO, 104LO that extend completely through both components in the front foot support region. Such openings are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: are shown as follows: The mouthparts 104UO, 104LO, in this illustrated embodiment, correspond to the front foot portions of the foot support bladder 200 and the fluid container 400, such that, if desired, at least portions of the top surface 4 00S of the fluid container 400 and the bottom surface 200S of the foot support bladder 200 face directly towards each other and / or are in direct contact with each other in at least the front foot support regions in the final assembled sole structure 104.

A multi-part cage component 300 including a side cage component 300L, an inner cage component 300M, and a central or rear cage component 300R is shown in FIG. 2B. The side cage component 300L, the inner cage component 300M engage corresponding sidewalls of the lower sole component 104L and / or corresponding sidewalls of the foot support bladder 200, and the central or rear cage component 300R engages the rear edge of the foot support bladder 200. If desired, (and as shown in FIG. 2B), at least one of the side cage component 300L and the inner cage component 300M may include an opening defined therebetween such that the sidewall(s) of the foot support bladder 200 are exposed and visible outside of the sole structure 104 in the final assembled sole structure 104.

[0043] As described above and as shown in the embodiments of FIGS. 3A - 3D, at least some embodiments of the present technology will include a fluid supply in the form of one or more pumps including one or more foot actuated pumps. If there is one pump, this pump can move fluid received from the external environment through a fluid passage extending from the external environment to the pump to a desired final destination (e.g., the foot support bladder 200, the fluid container 400, or back to the external environment) for distribution by the fluid distributor 500.

Alternatively, FIG. 3A shows a two - stage pumping device including a heel actuated valve pump 600H (also herein referred to as the "first pump"). As described above and as shown in the embodiments of FIGS. 3A - 3D, at least some embodiments of the present technology will include a fluid supply in the form of one or more pumps including one or more foot actuated pumps.

Alternatively, FIG. 3A shows a two - stage pumping device including a heel actuated valve pump 600H (also herein referred to as the "first pump"). The rear pump is connected "in series" to the front actuator valve pump 600F (also herein referred to as the "second pump") via the fluid line 602. Thus, in at least some embodiments of the present technology: (a) the inlet 600HI of the heel actuator valve pump 600H is in fluid communication with the external environment (by way of example, a fluid path extending from the external environment to the inlet 600HI through a fluid distributor 500 such as the fluid line 604); (b) the outlet 600HO of the heel actuator valve pump 600H is in fluid communication with the inlet 600FI of the front actuator valve pump 600 F via the fluid line 602; and (c) the outlet 600FO of the front actuator valve pump 600F is in fluid communication with the inlet of the fluid distributor 500 such as the fluid line 606. The "upstream" pump (herein 600H, but in some embodiments 600F could be) may be somewhat larger than the "downstream" pump (herein 600F, but in some embodiments 600H could be) in order to improve fluid flow and pumping efficiency. The two-stage pump may have features shown in the corresponding structure disclosed in U.S. Patent Application No. 16 / 698, 138, filed on November 27, 2019, and features such as, and / or, a structure.

[0044] In addition, or alternatively, if desired, when there are two or more pumps, two or more pumps may move fluid to the inlet of the fluid distributor 500 (by way of example, two or more pumps may directly connect their outlets to the inlet of the fluid distributor 500 ). Once delivered into the fluid distributor 500, the fluid distributor 50 0, according to its operating state, for example, the foot support bladder 200, the fluid container 400, etc., finally selectively moves fluid to a destination or returns the fluid to the external environment. Drain valves, also or check valves are present for any pumps 600H, 6 00F to prevent overpressure situations (for example, when the fluid line downstream of pumps 600H, 600F and / or fluid components are blocked or non-functional). The pump(s) 600F, 660H can be made, for example, from RF-welded TPU films adhered to each other to form a valve-type pumping chamber in a well-known manner.

[0045] Figure 3A generally illustrates the eccentric spherical or elliptical valve pumps 600H, 600F. On the other hand, Figures 3B - 3D generally show the T-shaped valve pumps 600H, 600F, and the front foot valve pump 600F is oriented in the direction under the metatarsal head support region of the sole structure 104 ( contrasted with being oriented in the direction of the toe support region in Figure 3A). Figure 3B shows the approximate location possible for the pumps 600H, 600F in the sole structure 104. Figure 3C shows the general arrangement of the pumps 600H, 600F and their connecting lines, and Figure 3 shows a close-up view of the T-shaped valve pump (e.g., 600H of this embodiment), which valve pump is in fluid communication with the front foot pump 600F, the fluid distributor 500, or other footwear components. can be.

[0046] The T-shaped valve pumps 600H, 600F distribute the pump chamber volume to a larger (e.g., wider) area of the user's foot (and thereby make the pump(s) 600H, 600F less perceptible at the foot), being slightly wider than an eccentric sphere or ellipse, for the purpose of distributing and also making the pumps 600H, 600F less perceptible at the foot. and can be made in non-round shapes. Such T-shaped valve pumps 600H, 600F can also be "connected in series" (as an example, the outlet 600HO of pump 600H is poured into the inlet 600F of pump 6 00F, and the outlet 600HI of pump 600F is a fluid di stributor 500, a foot support system, a sole structure 104, and / or a footwear 1 00's fluid source, for example, operating via a fluid line 606). The valve po mp 600H, 600F can be sandwiched between sole components, such as between a lower sole component 104L and one or more outsole structures 104. Alternatively, if desired, the forefoot outsole component can be provided to engage the forefoot pump 600F, and a separate heel outsole component can be provided to engage the heel pump. During use, when the user lands a step or jumps, the valve pumps 600H and / or 600F contract between the sole components under an applied force (the user's weight), thereby pushing fluid out of the outlets 600HO, 600FO of the valve pumps 600H and / or 600F, and moving the fluid from the pumps 600H, 600F to the fluid distributor 500. A one-way valve can be provided to prevent the reverse flow of fluid through the pump(s) 600F, 600H. The valve pump(s) 600H, 600F can be attached and / or positioned between flat or smoothly curved forms, bladders, outsoles, or other sole component surfaces (for example, to increase the pumping amount per step).

The fluid distributor 500 of the present embodiment includes a connector 700, a manifold 800, and a fluid transfer system 900.

[0048] The fluid transfer system 900 shown in FIG. 4A can take various forms and / or structures. FIG. 4B illustrates various exemplary arrangements for different types of the fluid transfer system 900 in the fluid distributor 500. The fluid transfer system in the upper right direction towards FIG. 4B includes a valve stem-based fluid transfer system 900A. The central fluid transfer system shown in FIG. 4B is a solenoid-based fluid transfer system 900B, 900C. The fluid transfer system in the lower left direction towards FIG. 4B is also a valve stem-based fluid transfer system 9 00D, provided that this fluid transfer system 900D includes a planetary gear type transmission 922B, in contrast to the gear train transmission 922 provided in the fluid transfer system 900A. Such different fluid transfer systems 900A, 900B, 900C, 900D (and their variations) are described in more detail below and can be included in the housing 502 of the fluid distributor 500.

[0049] Various fluid lines connect the fluid distributor 500 to various fluid starting locations and destinations. Such fluid lines are described in more detail in connection with the various operating states shown in FIGS. 5A - 5F. The large "X" in FIGS. 5A - 5F indicates the fluid path of the fluid transfer system 900, and the path can be blocked in its operating state. If necessary, such fluid paths can be blocked in any desired manner, for example, by a check valve or a one-way valve (e.g., from pumps 600H, 600F in fluid line 606), by the characteristics of the valve stem, by the configuration characteristics of the solenoid valve, etc.

[0050] FIG. 5A illustrates an operating state, in which fluid is pumped from the external environment 150 to the fluid drain. The air moves into the distributor 500 and is then expelled back to the external environment 150. The 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 the fluid container 400 is not required, the fluid The fluid pumped through the distributor 500 continues to move, forming a "start In this operating state, the external environment may be used as a "standby" or "steady" operating state. Fluid entering from the interface 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). Any desired intake size may be used, but in some embodiments of the present technology, The Ruta 702 is at least 50 mm 2 Area of ​​50mm 2 ~100mm 2 Area of ​​50m m 2 ~150mm 2 and 25mm 2 ~250mm 2 of area or other desired A filter such as a flat sheet of filter material, a flat screen, etc. 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, Possibly provide at least a majority of the surface area of one exposed outer surface of 702. Additionally, or alternatively, if desired, the filter can be provided within the connector 700 and / or at other locations within the fluid flow path (by way of example, a pump (plural) 600H, 600F that extends at least partially within the connector 70 0 body and at least partially within the dedicated fluid path 702P, somewhat upstream of the inlet of the pump (plural), etc.).

[0051] The fluid passes through the connector body from the connector inlet 702I (by way of example, through the fluid path 702 P or through the internal open space 710 within the connector 700), and exits through the port 702O. In some embodiments of the present technology, the dedicated fluid path 702P ( by way of example, a closed fluid tube) can be omitted (or made discontinuous with the open end within the internal space 710 of the connector 700), such that the fluid can enter the internal open space 710 from the connector inlet 702I and / or flow out of this internal open space 710 through the opening provided as the port 702O. In such embodiments, the internal open space 710 can be regarded as at least a part of the fluid path 702P passing through the connector 700. The outlet 702O is connected to the fluid path 604, which sends the fluid to the pump system (in this embodiment, the pump (plural) 600H, 600F and the fluid line 60 2 connecting the pumps). The fluid descends from the pump (plural) 600H, 600F along the fluid line 606 and returns to the inlet port 704 of the connector 700. A one-way valve or a check valve along the fluid line 606 is provided at the connector inlet port 704 and / or along the fluid line 60 ​​​​​​​​​To prevent fluid from flowing backward through 6 towards the pump(s) 600H, 600F, it may exist. The fluid passes through the connector 700 via the connector inlet port 704 and the connector fluid path 704P (also referred to herein as the "fourth connector fluid path") and flows to the connector outlet port 704O (also referred to herein as the "fourth fluid path connector"), and flows into the inlet fluid port 800A of the manifold 800. The fluid passes from the inlet fluid port 800A through the fluid inlet path 802 in the manifold 800, through the fluid inlet port 800I, and flows into the fluid transfer system 900. In this operating state, the fluid exits the fluid transfer system 900, passes through the first manifold port 804, passes through the first manifold fluid flow path 806 defined in the manifold 800, passes through another manifold port 800B, reaches the first fluid path connector (or port) 706 of the connector 700, passes through the first connector fluid path 708, and optionally reaches the external environment 150. Additionally, or alternatively, the fluid passing through the first fluid path connector 706 may flow into the internal space 710 within the connector 700 (and thereby become part of the external environment) and / or may be utilized as part of another pump cycle. In some embodiments of the present technology, in this operating state, when it will simply be discharged and returned to the external environment 150, instead of continuously moving the fluid through the fluid distributor 500 at each step, an optionally operable fluid path may be provided that discharges directly from the pump(s) 600H, 600F into the external environment 150.

[0052] ​​​​​​​​​​​​​​​​It would be. As another option, if no change in fluid pressure is required, the pump(s) 600H, 600F may be stopped.

[0053] Figure 5B shows an operating state in which fluid moves from the external environment 150 into the fluid distributor 500 and is transferred to the foot support bladder 200 feet. Further, the fluid flow in this operating state is indicated by the thick dashed line with arrows. This operating state can be used, for example, to increase the pressure in the foot support bladder 200 for a more stable feeling and / or more intense activities (such as running). In this operating state, the fluid flowing in from the external environment 150 (e.g., the atmosphere) enters the fluid transfer system 900 through the connector 700 and the manifold 800 in the same manner as described above for Figure 5A (and through the same components). However, in this operating state, the fluid exits the fluid transfer system 900, passes through the second manifold port 808, through the second manifold fluid flow path 810 defined in the manifold 800, through another manifold port 800C, to the second fluid path connector (or port) 712 of the connector 700, through the second connector fluid path 714, through another connector port 720, into the foot support fluid line 202, and into the foot support bladder 200. and is transferred to the foot support bladder 200 feet. Further Moreover, the fluid flow in this operating state is indicated by the thick dashed line with arrows. This operating state can be used, for example, for a more stable feeling and / or more intense activities (such as running), to increase the pressure in the foot support bladder 200. In this operating state, the fluid flowing in from the external environment 150 (e.g., the atmosphere) enters the fluid transfer system 900 through the connector 700 and the manifold 800 in the same manner as described above for Figure 5A ( and through the same components), through the connector 700, through the manifold 800 and into the fluid transfer system 900. However, in this operating state, the fluid flows out of the fluid transfer system 900, passes through the second manifold port 808, through the second manifold fluid flow path 810 defined in the manifold 800, through another manifold port 800C, to the second fluid path connector (or port) 712 of the connector 700, through the second connector fluid path 714, through another connector port 720, into the foot support fluid line 202, and into the foot support bladder 200. 800, through the second manifold fluid flow path 810 defined in the manifold 800, to another manifold port 800C, to the second fluid path connector (or port) 712 of the connector 700, through the second connector fluid path 714, through another connector port 720, into the foot support fluid line 202, and into the foot support bladder 200.

[0054] In some applications, it may be desirable to remove fluid from the foot support bladder 200 to reduce the pressure in the foot support bladder 200 (e.g., to provide a softer feeling or for less intense activities such as walking or casual wear). For example, to provide a softer feeling, or for less intense activities such as walking or casual wear, it may be desirable to remove fluid from the foot support bladder 200. Therefore). An example of this operating state is shown in FIG. 5C, and the fluid flow is shown by the dashed line with thick arrows. In this operating state, the fluid exits the foot support bladder 200, enters the foot support fluid line 202, enters the second connector fluid path 714 via the connector port 720, and reaches the second fluid path connector 712 of the connector 700. From the second fluid path connector 712 of the fluid, it passes through the manifold port 800C and enters the second manifold fluid flow path 810 defined in the manifold 800, passes through the second manifold port 808, and enters the fluid transfer system 900. From here, in this exemplary system and in the operating state, the fluid is discharged to the external environment 150. This is caused by the fluid exiting the fluid transfer system 900, passing through the first manifold port 804, passing through the first manifold fluid flow path 806 defined in the manifold 800, passing through the manifold port 800B, reaching the first fluid path connector (or port) 706 of the connector 700, and reaching the external environment 150 (this environment may constitute the internal space 710 within the connector 700) through the first connector fluid path 708. The first connector fluid path connector (or port) 706 can form a port that allows the fluid to be discharged from the entire system (the "fluid discharge port") and return to the connector 700. According to some embodiments of the present technology, another possible operating state for the fluid distributor 500 and the foot support system is shown in FIG. 5D. In this operating state, for example, to reduce the fluid pressure in the fluid container 400, the fluid is discharged from the fluid container 400 to the external environment.

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 the connector port 722; and The fluid passes through a third fluid pathway 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 a 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 operating conditions, 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 8 through a first manifold fluid flow path 806 defined in the manifold port 800; 800B to a first fluid pathway connector (or port) 706 of connector 700. and through a first connector fluid path 708 to an 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 the fluid flow from pressure spikes caused by foot contact with the ground, and The transfer 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 the connector port 722; and The fluid passes through the third fluid pathway connector 718 of the connector 700. 718, through manifold port 800D, and into manifold 800. The fluid then enters third manifold fluid flow path 812 and passes through third manifold port 814. and into the fluid transfer system 900. From here, this exemplary system, In an operating state, fluid is transferred to the foot support bladder 200. This is the fluid transfer system 900, passes through a second manifold port 808, and is defined within the manifold 800. through a second manifold fluid flow path 810 through manifold port 800C; , leading to a second fluid path connector 712 of the connector 700 and forming a second connector fluid path 714. 2 through the foot support fluid line 202 to the connector port 720 and into the foot support fluid line 202. The pressure is generated by the fluid entering the retainer 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 the connector 700 via the connector inlet 702I. 2I through the connector body to the connector outlet port 702O and through the fluid Path 604, which directs the fluid to a pump system (pump(s) 600H, 600 F). The fluid descends from the pump(s) 600H, 600F through the fluid line 606 and returns to the inlet port 704 of the connector 700. A one-way valve along the fluid line 606, or a check valve, may be present to prevent the fluid from flowing back through the connector inlet port 704 and / or the fluid line 606 towards the pump(s) 600H, 600F.

The port 800A of the present embodiment connects to the port 704O on the connector 700 body that is in fluid communication with the fluid line 704P, receives the inflowing fluid from the fluid line 606 (and thus from the pump(s) (600H, 600F)), and conveys the inflowing fluid into the manifold 800 and / or the fluid transfer system 90 0. The port 800B of the present embodiment connects to the port 706 on the connector 700 body, and discharges excess or undesirable fluid back to the external environment (e.g., through the connector 700 body). The port 800C of the present embodiment connects to the port 712 on the connector 700 body, and exchanges fluid (in either direction) between the foot support bladder 200 and the manifold 800. The port 800D of the present embodiment connects to the port 718 on the connector 700 body, and exchanges fluid (in either direction) between the fluid container 400 and the manifold 800. As shown particularly in FIGS. 11A and 11B, the ports 800A, 800B, 800C, and 800D of the manifold 800 can be aligned along one surface 7 50A of the housing 750 and / or along the manifold 800 (and, if desired, can extend parallel, at least in part, through the housing 750 and / or the manifold 800). 50A, and / or along the manifold 800 (and, if desired, can extend parallel, at least in part, through the housing 750 and / or the manifold 800). extendable in a row). The ports 704O, 706, 712, and 718 of the connector 700 (each connected to the manifold ports 800A, 800B, 800C, and 800D respectively) can be aligned along a surface 704S of the connector 700 (and, if desired, can extend at least partially parallel through the connector 700). In this illustrated embodiment, the ports 704O, 706, 712, and 718 of the connector 700 are positioned somewhat below and then offset from the connector ports 704, 702O, 720, and 722 respectively on the surface 704B of the connector 700. The surfaces 704S, 704B can form a common surface on the connector 700, can be offset from each other, can be different from each other, and can face in

[0065] FIG. 11B further illustrates that one or more of the connector fluid paths 704P, 714, 716 can define a curved or bent path. One or more of the connector fluid paths 704P, 714, 716 can include: (a) a first axial direction 700AX1, (b) a second axial direction 700AX2, and (c) a connection portion 700CP that joins the first axial direction 700AX1 and the second axial direction 700AX2. The first axial direction 700AX1 and the second

[0066] axial direction 700AX2 extend away from each other at an angle of 70 degrees or less from the connection portion 700CP. Furthermore, as shown in FIGS. 11A and 11B, the connector 700 of this . In this embodiment, the fluid paths 704P, 714, and 716 pass through the connector 700 body to form a curved or bent path. The fluid can enter and exit the connector 700 from the same general side surface and / or in the same general direction (e.g., as shown in FIG. 11B).

[0067] FIGS. 12A - 12C further illustrate the connection between the connector 700 and the housing 750 of FIGS. 11A and 11B, highlighting some additional possible features. As shown in such figures, the sealing system 760 is provided between the ports 800A, 800B, 800C, 800D of the manifold 800 and the ports 704O, 706, 712, 718 of the connector 700, respectively. The sealing system 760 includes female engagement parts (e.g., channels 760A, 760B, 760C, 760D), which externally fit onto male engagement parts (e.g., the tubular structures forming the outer surfaces of the ports 800A, 800B, 800C, 800D) to sealingly engage the manifold 800 with the connector 700. The other ends of the channels 760A, 760B, 760C, 760D can sealingly engage the connector 700 and can be aligned (and / or formed) with the connector ports 704O, 706, 712, 718.

[0068] FIGS. 13A - 13C illustrate different connections between the housing 750 and the external fluid lines 202, 402, 604, 606. In this embodiment, the connector 700 is not a separate part that engages the manifold 800; rather, the connector 700 forms part of the manifold 800 and / or is fixed within the housing 750. In this regard, the fluid line 20 ​​​​​​​​​​​​​​​2, 402, 604, and 606 have male connector parts at their ends, and these parts form the ports 704, 702O, 720, 722 of the connector 700 part of the manifold 800 and extend into the openings. In this structure, fluid can enter and exit the connector 700 from different sides or surfaces 704S, 704B of the connector 700, and / or in different directions. This results in a different connection between the connector 700 and the housing 750 as shown in FIGS. 13A - 13C compared to the fluid flow path shape between the connector 700 and the housing 750 shown in FIGS. 11A - 12C (i.e., in this embodiment, the shapes of the connector fluid paths 704P, 7 14, 716 are different). FIGS. 13A - 13C further show one or more retainer clips lip 752 (one clip 752 engaging all of the fluid lines 202, 402, 604, 606 in FIGS. 13A - 13C is shown) fixing the fluid lines 202, 402, 604, 606 to the outer surface 750S of the housing 750 (these lines extend from an internal location within the footwear 100). The retainer clip(s) 752 helps to hold the fluid lines 202, 402, 604, 606 in the correct position relative to the housing 750, preventing twisting, breakage, etc., and / or assisting in assembly.

Figures 18A - 18C show various ways in which the receiver coil 514 can be incorporated, for example, into a fluid distributor 500 of the type described above (under the cap 506, or a part thereof, etc.). The fluid distributor 500 (e.g., its housing 750, cap 506, etc.) includes a magnet 520 for removably coupling a charge pack (e.g., 1102, 1102A, 1102B, another structure) for inductive coupling and charging.

FIGS. 2 2A to FIGS. 22E provide additional information regarding possible embodiments for unlocking the user interface switch or the system 2200 and / or for changing pressure at a certain part in the foot support system. The "No Entry" zone shown in FIG. 22A coincides with the area of the housing 502, which area includes a coil for magnetic charging as described above ("No Entry" means that the "real estate" below that area is immediately claimed for the coil or other structures, and thus the circuit and / or components for the user interface switch 2200 cannot be accommodated).

[0087] FIG. 22A provides various option charts for unlocking and using the user interface switch or the system 2200 and its operations. FIGS. 22B to FIGS. 22E provide diagrams of possible structures for such an input system (FIG. 22A, Example 4 is particularly illustrated). In FIG. 22A, Example 1, the button is a capacitive type button (e.g., detecting the user's finger touch by the capacitive coupling of the structure, as is well known and used in the related art). This exemplary user interface switch or system 2200 is unlocked by a swipe operation of the button, and a change in pressure is also input by a swipe operation (e.g., swiping to the right (in the direction When it is 2B and in the direction of 506A, the pressure is increased in a predetermined amount or in steps. One swipe can be used for both unlocking the user interface switch, i.e., the system 2200, and introducing a pressure change input. As an example, initially "touching" and starting a swipe can unlock the user interface switch or the system 2200 and, if necessary, activating it, and continuing the swipe operation (left or right) can provide a pressure change input. Additionally, or alternatively, as an example, the first swipe unlocks the user interface switch or the system 220 0 and / or activates it, and the second swipe can provide a pressure change input. For example, two swipes can be used or required, such as the first swipe unlocks the user interface switch or the system 2200 and / or activates it, and the second swipe provides a pressure change input. In FIG. 22A, in Example 2, the button is a capacitive type button (e.g., including capacitive sensing electrodes of a structure well-known and used in the relevant art). This exemplary user interface switch or the system 2200 is unlocked by a swipe operation of the button, and the change in pressure is input by touch operations on both sides of the center (e.g., touching the right side surface 506B reduces the pressure by a predetermined amount, and touching the left side surface 506A increases the pressure by a predetermined amount).

[0088] In FIG. 22A, in Example 2, the button is a capacitive type button (e.g., including capacitive sensing electrodes of a structure well-known and used in the relevant art).

It may be that this button requires two physical presses, one press to unlock the user interface switch or the system 2200, and another press to input information about the desired pressure increase or decrease. As another option (the option under Examples 3 and 4 shown in the table), buttons 2200A and 2200B may be a combination of a capacitive touch button (used to unlock the user interface switch or the system 2200) and a tactile button (used to change the pressure setting). In the options under such Examples 3 and 4, the system (a) operates by the initial "touch" operation to unlock the user interface switch or the system 2200 and / or activate, and then (b) changes the pressure setting by a button press operation (with buttons 2200A and 2200B). One difference between the buttons in Examples 3 and 4 of FIG. 22A relates to the location of buttons 2200A and 2200B with respect to the "no entry" zone. In Example 3, buttons 2200A and 2200B are adjacent to each other on the same side of the button and on the same side of the "no entry". In Example 4, buttons 2200A and 2200B are separated from each other by the no entry zone and are at different ends of the button. In FIG. 22A, the button with the "button press" or "press" label may constitute a physical switch type button actuator. The tactile button (e.g., of a structure well-known and used in the relevant art) may have an outer surface that gives a different tactile sensation. As one example, the exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a convex outer surface, and the other button (e.g., the pressure decrease button 2200B) may have a concave outer surface. Another example is that the exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a rough outer surface, and the other button (e.g., the pressure decrease button 2200B) may have a smooth outer surface. The exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a pattern, and the other button (e.g., the pressure decrease button 2200B) may have a plain surface. The exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a raised texture, and the other button (e.g., the pressure decrease button 2200B) may have a recessed texture. In addition to the above, the tactile button may be made of a material with different hardness. For example, one button (e.g., the pressure increase button 2200A) may be made of a relatively hard material, and the other button (e.g., the pressure decrease button 2200B) may be made of a relatively soft material. The tactile button may also have a different shape. For example, one button (e.g., the pressure increase button 2200A) may be circular, and the other button (e.g., the pressure decrease button 2200B) may be square. The tactile button may have different sizes. For example, one button (e.g., the pressure increase button 2200A) may be larger, and the other button (e.g., the pressure decrease button 2200B) may be smaller. The tactile button may be arranged in different positions. For example, in one embodiment, the pressure increase button 2200A may be on the left and the pressure decrease button 2200B may be on the right; in another embodiment, the pressure increase button 2200A may be on the top and the pressure decrease button 2200B may be on the bottom. The tactile button may be combined with other components. For example, it may be combined with an indicator light. When the pressure increase button 2200A is pressed, the indicator light may turn on to indicate an increase in pressure; when the pressure decrease button 2200B is pressed, the indicator light may turn on to indicate a decrease in pressure. The tactile button may also be combined with a sound device. When the pressure increase button 2200A is pressed, a certain sound may be emitted to indicate an increase in pressure; when the pressure decrease button 2200B is pressed, a different sound may be emitted to indicate a decrease in pressure. In Example 3, buttons 2200A and 2200B are adjacent to each other on the same side of the button and on the same side of the "no entry". In Example 4, buttons 2200A and 2200B are separated from each other by the no entry zone and are at different ends of the button. In FIG. 22A, the button with the "button press" or "press" label may constitute a physical switch type button actuator. The tactile button (e.g., of a structure well-known and used in the relevant art) may have an outer surface that gives a different tactile sensation. As one example, the exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a convex outer surface, and the other button (e.g., the pressure decrease button 2200B) may have a concave outer surface.

[0090] Another example is that the exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a rough outer surface, and the other button (e.g., the pressure decrease button 2200B) may have a smooth outer surface. The exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a pattern, and the other button (e.g., the pressure decrease button 2200B) may have a plain surface. The exposed pressing surface of one button (e.g., the pressure increase button 2200A) may have a raised texture, and the other button (e.g., the pressure decrease button 2200B) may have a recessed texture. The exposed pressing surface of the force reduction button 2200B may have a concave surface. Another option is, as shown in FIG. 6, to provide different tactile sensations, one side of the button 506 is recessed or may be marked with a raised "plus" sign ("+"), and the opposite side is recessed or may be marked with a raised "minus" sign ("−"). In this way, the user can even when wearing shoes, more easily identify the correct button location and make contact with it in order to change the desired pressure.

[0091] FIGS. 22B to 22E provide various views of an exemplary button structure for the "touch / press" option of Example 4 of FIG. 22A. FIG. 22B shows flexure regions 2202A, 2202B corresponding to the locations 2200A, 2200B of physical tactile buttons overmolded (or formed by a two-shot molding process) with a rubber or other polymer (e.g., silicone, or other elastomer) construction. Grooves 2204A, 2204B extending partially through the overmold material 2210 around the button actuator region form a thin layer of rubber or other material to enable excellent flexure when buttons 2200A, 2200B are pressed. Such grooves 2204A, 2204B can also provide the aforementioned tactile feature. The flexure regions 2202A, 2202B may include a base portion having an overmold material of an elastomer with a first thickness (e.g., 2 mm to 10 mm thick as an example), and the grooves 2204A, 2204B have a second thickness less than the first thickness (e.g., 0.5 mm to 3 mm thick). The first thickness of the overmold material in the base portion is , it can be 1.5 to 2 times thicker than the second thickness of the overmolded material in grooves 2204A and 2204B. times thicker.

[0092] In this embodiment, when buttons 2200A and 2200B are pressed, the overmolded material in grooves 220 4A and 2204B stretches somewhat due to the applied force. When the force from button pressing decreases or is removed, the stretched material in grooves 2204A and 2204B returns toward the non-stretched configuration, providing a return energy. This return energy can give an interesting tactile sensation to the user's finger, somewhat of a "bouncing" or "trampoline" effect. The overmolded material 2210 also serves to close the button area and prevent water, dust, or other unwanted substances from entering the interior of housing 502. The flexure regions 2202A and 2202B can be formed as part of a cap 506 placed on housing 750 of fluid distributor 500 and / or as the upper surface of housing 750 of fluid distributor 500. However, if desired, the grooves 2204A and / or 2204B in flexure regions 2202A and / or 2202B can be replaced by through holes. Optionally or if desired, other sealing components (e.g., elastomeric gaskets, O-rings, etc., see FIG. 22E) can be provided in such a system to seal the button openings and / or provide a "bouncing" or "trampoline" effect. placed on housing 750 of fluid distributor 500 and / or as the upper surface of housing 750 of fluid distributor 500. However, if desired, the grooves 2204A and / or 2204B in flexure regions 2202A and / or 2202B can be replaced by through holes.

[0093] The grooves 2204A and 2204B in FIG. 22B can have any desired shape(s) without departing from the present technology. The grooves are located adjacent to the button actuator area. ​​​Possible (e.g., on and / or around the hardware necessary to activate the button) ) In the illustration of the embodiment of FIG. 22B, the grooves 2204A, 2204B are generally U-shaped and have free ends that face each other, i.e., open ends. The free ends, i.e., open ends, can also face other directions (plural possible) including away from each other and towards other surfaces of the button . In other embodiments, the grooves 2204A, and / or 2204B can form a closed path around the button actuator region .

As an example, various components may be attempting to connect to each other. may attempt to maintain a connection with each other and / or may attempt to reconnect with each other, To illustrate the sequence, the interaction and communication of the other components is shown in FIG.

[0098] In the arrangement shown in FIG. 25, shoes 2502, 2504 can communicate directly with each other. Further in some connection protocols, in the case of direct communication: (a) either shoe 2502, 2504 can function as a "central" communication point (providing input and information to the other shoe), and / or as a control device 2500, and (b) either shoe 2502, 2504 can function as a "peripheral" communication point (receiving input and information from the other shoe, and / or the control device 2500).

[0100] Various embodiments of the structure and operation of the fluid transfer system 900 are described in more detail in the subsequent section s. Some aspects of the fluid transfer system 900 in accordance with the present technology relate to a valve stem within a valve housing that opens and closes various fluid passages through the manifold 800. Other aspects of the fluid transfer system 900 in accordance with the present technology relate to a solenoid-based system that selectively opens and closes to control the fluid flow through the manifold 800. B. Features of the Valve Stem-Based Fluid Transfer System

[0101] Figures 26A - 26D provide various views of an exemplary fluid distributor 500 that includes a movable valve stem type fluid transfer system 900A in accordance with aspects of the present technology. As described above, this exemplary fluid distributor 500 includes a housing 502, as well as a connector 700. A manifold 800 and a fluid transfer system 900A are housed within the housing. The connector engages fluid sources (e.g., external environments, pumps 600H, 600F, compressors, etc.), an external environment 150, at least one foot support bladder 200, and at least one fluid container 400 within the housing 502. Figures 26A - 26D further show the location of the fluid transfer system 900A for supplying power to various electrical or electronic components, as well as the rechargeable battery 2602. Figures 27A - 29 show an exemplary manifold 800 and

[0102] in accordance with some aspects of the present technology. Also, additional details regarding the components of the exemplary fluid transfer system 900A are provided. In this embodiment, the manifold 800 includes a manifold body or housing 820. Referring also to FIGS. 5A-5F, one surface 822A or side of the manifold body 820 has ports 800A, 800B, 800C, 800D that are in fluid communication with corresponding ports 704O, 706, 712, 718 of the connector 700, respectively. The opposite surface 822B (which may be another surface) of the manifold body 820 has an inlet port 800I, a first manifold port 804, a second manifold port 808, and a third manifold port 814. A fluid inlet path 802 extends between port 800A and the fluid inlet port 800I, a first fluid flow path 806 extends between port 800B and the first manifold port 804, a second fluid flow path 810 extends between port 800C and the second manifold port 808, and a third fluid flow path 812 extends between port 800D and the third manifold port 814. Thus, in this illustrated embodiment, the manifold 800 includes four separate passages that extend through the manifold. The manifold 800 of this embodiment further includes at least one pressure sensor (two pressure sensors 850A, 850B shown in FIGS. 27A-28). The pressure sensor(s) 850A, 850B may be positioned in at least one of the first fluid flow path 806, the second fluid flow path 810, or the third fluid flow path 812 to determine fluid pressure. In some more specific embodiments, a first pressure sensor 850A may be provided to determine the fluid pressure in the third fluid flow path 812 (and thus in the fluid container 400), and in the first fluid flow path 806, ​ Alternatively, a second pressure sensor 850B may be provided to determine the fluid pressure in at least one of the second fluid flow paths 810 (e.g., the pressure in the foot support bladder 200). An O-ring 852 (or gasket, and / or other suitable sealing device) may be provided to sealingly engage the pressure sensor(s) 850A, 850B with the manifold body 820.

[0103] The illustrated fluid transfer system 900A of this embodiment includes a valve housing 902 and a valve system 910 movably (e.g., rotatably, slidably, etc.) mounted within the valve housing 902. The valve system 910 of this embodiment includes a first end 910A (e.g., a drive end) and a second end 910B (e.g., a free end) opposite the first end 910A. A peripheral wall 910W extends between the first end 910A and the second end 910B. The first end 910A, the second end 910B, and the peripheral wall 910W define an internal chamber 910I of the valve system 910. Further, the peripheral wall 910W of the valve system 910 includes a plurality of through holes 910H extending from the internal chamber 910I toward the peripheral wall 910W and the outer surface of the valve system 910. As will be described in more detail below (e.g., in connection with FIGS. 30A - 30G), movement of the valve system 910 to a plurality of positions selectively positions this fluid flow control system (e.g., fluid distributor 500, fluid transfer system 900A, a combination of manifold 800 and fluid transfer system 900A, etc.) in a plurality of operating states by placing one or more of the plurality of through holes 900H in fluid communication with the first fluid flow path 806, the second fluid flow path 810, and / or the third fluid flow path 812. ​​​​​​​​​​​​​​​​

[0104] Figures 27A - 29 further illustrate that this exemplary fluid transfer system 900A includes a drive system (e.g., , motor 920), and a transmission 922 (including output gears, nose pins, cup seals, and other gears, described in more detail below). The transmission 922 components transmit power from the motor 920 to the first end 910A of the valve system 910 to move (rotate in this example) the valve system 910 relative to the valve housing 902 (and manifold 800). A power source (e.g., rechargeable battery 2602), and a microcontroller (comprising fluid distributor 500 and not shown in Figures 27A - 29) selectively drive the motor 920 to position the valve system 910 at one of a plurality of positions, enabling fluid movement from a desired starting point to a desired location.

[0105] This exemplary fluid transfer system 900A further includes an encoder system (e.g., an on - shaft magnetic encoder system, an off - shaft magnetic encoder system, etc.) including encoder magnet 932 and encoder board 934 to detect the position (e.g., rotational position) of the valve system 910 relative to the housing 902 and / or other components. The encoder system supplies data indicating this position to the microcontroller. Such encoder systems are commercially available and their operation is well - known in the relevant art.

[0106] In this exemplary fluid transfer system 900A, the valve housing 902 engages sealingly with the manifold body 820. This seal can be achieved in various ways, but in the illustrated In an embodiment, between the peripheral wall 910W of the valve stem 910 and one or more of the fluid inlet port 800I, the first manifold port 804, the second manifold port 808, and / or the third mani fold port 814, one or more sealing connectors 840 are provided therein. The sealing connector 840 extends into a recess 902R on one side of the valve housing 902. In this illustrated embodiment, one sealing connector 840, or a sealing block, includes three sealing ports 840A, 840B, 840C. The three sealing channels 842A, 842B, 842C passing through the sealing connector 840 are connected to the first manifold port 804, the second manifold port 808, and the third manifold port 814, respectively. In this way the sealing channels 842A, 842B, 842C are in fluid communication with the first fluid flow path 806, the second fluid flow path 810, and the third fluid flow path 812 of the manifold body 820, respectively. In addition, or alternatively, if desired, another sealing port and another sealing ch annel can be provided in the sealing connector 840 to connect the fluid inlet port 800I of the manifold 800 to the valve housing 902. However, in the specific embodiment of FIG. 29, the fluid intake path 802 from the manifold port 800A to the fluid inlet port 800I is directly connected to the valve housing 902, and the fluid intake path 902A extends through the valve housing 902 and allows the inflowing fluid to enter the internal chamber 910I of the valve stem 910 through its open second end 910B. Refer to the fluid passage 902P shown by the dashed line in FIG. 29. See also, as shown in FIG. 29, the first manifold port 804, the second manifold port 808, and the third manifold port 814 are directly connected to the valve housing 902, and the fluid intake path 802 from the manifold port 800A to the fluid inlet port 800I is directly connected to the valve housing 902. The fluid intake path 902A extends through the valve housing 902 and allows the inflowing fluid to enter the internal chamber 910I of the valve stem 910 through its open second end 910B. Refer to the fluid passage 902P shown by the dashed line in FIG. 29. through the valve housing 902 and allows the inflowing fluid to enter the internal chamber 910I of the valve stem 910 through its open second end 910B. Refer to the fluid passage 902P shown by the dashed line in FIG. 29. See the fluid passage 902P shown by the dashed line in FIG. 29. .

[0107] Furthermore, as shown in FIG. 29, the first manifold port 804, the second manifold Port 808 and the third manifold port 814 are on the outer side of the manifold 800 and are aligned along it. Additionally, or alternatively, if desired, manifold ports 80 0A, 800B, 800C, 800D are aligned along the outer side of the manifold 800 (and in the illustrated embodiment shown, on the opposite surface of the manifold 800 from ports 804, 808, 814). Any two or more of the fluid flow paths 802, 806, 810, and 812 are aligned in parallel and / or extend through the manifold body 820 and can be obtained. Additionally, or alternatively, any two or more of the sealing channels 842A, 842 B, 842C of the sealing connector 840 are aligned in parallel and / or extend through the sealing connector 840 body and can be obtained.

[0108] The valve stem 910 can place the fluid transfer system 900A in two or more operating states depending on the position of the valve stem 910 relative to the housing body 902 . The movement of the valve stem 910 changes the positioning of the through - hole 910H through the peripheral wall 910W of the valve stem 910 and enables different holes 910H to align with the ports 840A, 840B, 840C of the sealing connector 840. The valve stem 910 can be moved (e.g., rotated, etc.) under the control of a microprocessor that controls the motor 920 . Figures 30A - 30G provide additional details regarding various operating states, which states can be provided and used in the footwear article 100 including the fluid distributor 500, the foot support system, the sole structure 104, and the fluid transfer system 900A in accordance with aspects of the present technology. This discussion assumes the following as shown in FIG. 29: (a) The manifold port 800A is for the pump(s) 6 and (b) the manifold port 800B is for the fluid distributor 500 and (c) the manifold port 800C is for the foot support system and (d) the manifold port 800D is for the sole structure 104 and (e) the fluid transfer system 900A includes a pump(s) 6, a valve stem 910, and a sealing connector 840 and (f) the valve stem 910 is movable under the control of a microprocessor that controls the motor 920 in fluid communication with a fluid source such as 00H, 600F (e.g., via connector ports 702I, 70 4O, and the ports thereof, or other suitable components that connect fluid lines) introduce fluid into the fluid transfer system 900A; (b) the manifold port 800B is in fluid communication with the external environment 150 (e.g., via connector port 706, and fluid path 708 and / or other suitable fluid lines) to discharge any excess fluid in the fluid transfer system 900A to the external environment 150; (c) the manifold port 800C is in fluid communication with the foot support bladder 200 (e.g., via connector ports 712, 720, and fluid line 714 and / or other components that connect them) to increase or decrease the fluid pressure in the foot support bladder 200; and (d) the manifold port 800D is in fluid communication with the fluid container 400 (e.g., via connector ports 718, 722, and fluid line 716, and / or other components that connect them) to increase or decrease the fluid pressure in the fluid container 400. Also note the relationship and description of the operating states shown and described in connection with FIGS. 5A - 5F as well. As described above, in this exemplary fluid distributor 500, the valve stem 910 is rotated to move to different positions to place the fluid distributor 500, the foot support system, the sole

[0109] structure 104, and / or the footwear 100 in different operating states. Any number of operating states may be provided, but in the illustrated embodiment, the valve stem 910 is rotated to assume six different operating states as shown in FIGS. 30A - 30G. FIG. 3 0A shows a clockwise (e.g., from operating state 1 to operating state 6) or counterclockwise (e.g., from operating state 6 to operating state 1) rotation, and the valve stem 910 can be rotated to six different operating states as shown in FIGS. 30A - 30G. FIG. 3 0A shows a clockwise (e.g., from operating state 1 to operating state 6) or counterclockwise (e.g., from operating state 6 to Schematically illustrate various positions of the valve stem 910 when rotated to the operating state 1. This According to some aspects of the technology, in some pressure control methods, the "standby" state is almost a representative state in the case (when no pressure change occurs). The valve stem 910 rotates an appropriate amount to enter the desired operating state (e.g., operating states 2 to 6), waits until the pressure reaches the desired level (measured by the pressure sensor(s) 850A, 850B), and then rotates back to the standby state.

[0110] The operating state 1 of this embodiment is the "standby" or "idle" state. In this state, the fluid pumped out by the pump at each step simply passes through the system, for example, from the pump(s) 600H, 600F through the manifold 800, through the fluid transfer system 900A, back through the manifold 800, and to the external environment 150. Refer to FIG. 30B. The operating state 1, for example, when a foot-operated pump is used and is operated during each step to move the fluid, prevents any part of the entire foot support system from being over-pressurized.

[0111] The operating state 2 (e.g., the state where the valve stem 910 is rotated 60 degrees clockwise from the operating state 1) is a "pumping" state in which fluid is moved from the pump(s) (or other fluid source) to the foot support bladder 200. In the operating state 2, the fluid pumped out by the pump during the steps passes through the system (e.g., from the pump(s) 600H, 600F through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800). ) and enters the foot support bladder 200. Refer to FIG. 30C. This operating state can be used to rapidly and / or directly increase the fluid pressure in the foot support bladder 200 (e.g., the "inflated" configuration of the foot support bladder 200). It can be used to rapidly and / or directly increase the fluid pressure in the bladder 200 (e.g., the "inflated" configuration of the foot support bladder 200). It can be used to rapidly and / or directly increase the fluid pressure in the foot support bladder 200 (e.g., the "inflated" configuration of the foot support bladder 200).

[0112] Operating state 3 (e.g., rotating the valve stem 910 60 degrees clockwise from operating state 2) is the "live" state that moves fluid from the foot support bladder 200 to the external environment 150. In operating state 3, the fluid passes through the system (e.g., from the foot support bladder 200 through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800) and reaches the external environment 150. Refer to FIG. 30D. This operating state can be used to release the fluid in the foot support bladder 200 and reduce the fluid pressure (e.g., the "contracted" configuration of the foot support bladder 200). It is the "live" state that moves fluid from the foot support bladder 200 to the external environment 150. In operating state 3, the fluid passes through the system (e.g., from the foot support bladder 200 through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800) and reaches the external environment 150. Refer to FIG. 30D. This operating state can be used to release the fluid in the foot support bladder 200 and reduce the fluid pressure (e.g., the "contracted" configuration of the foot support bladder 200).

Refer to FIG. 30D. This operating state can be used to release the fluid in the foot support bladder 200 and reduce the fluid pressure (e.g., the "contracted" configuration of the foot support bladder 200). and reaches the external environment 150. Refer to FIG. 30D. This operating state can be used to release the fluid in the foot support bladder 200 and reduce the fluid pressure (e.g., the "contracted" configuration of the foot support bladder 200).

This operating state can be used to release the fluid in the foot support bladder 200 and reduce the fluid pressure (e.g., the "contracted" configuration of the foot support bladder 200).

[0113] Operating state 4 (e.g., rotating the valve stem 910 60 degrees clockwise from operating state 3) is also the "live" state that moves fluid from the fluid container 400 to the external environment 150. In operating state 4, the fluid passes through the system (e.g., from the fluid container 400 through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800) and reaches the external environment 150. Refer to FIG. 30E. This operating state can be used to release the fluid and reduce the fluid pressure in the fluid container 400 (e.g., the "contracted" configuration of the fluid container 400). It is also the "live" state that moves fluid from the fluid container 400 to the external environment 150. In operating state 4, the fluid passes through the system (e.g., from the fluid container 400 through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800) and reaches the external environment 150. Refer to FIG. 30E. This operating state can be used to release the fluid and reduce the fluid pressure in the fluid container 400 (e.g., the "contracted" configuration of the fluid container 400). In operating state 4, the fluid passes through the system (e.g., from the fluid container 400 through the manifold 800, through the fluid transfer system 900A, and back through the manifold 800) and reaches the external environment 150. Refer to FIG. 30E. This operating state can be used to release the fluid and reduce the fluid pressure in the fluid container 400 (e.g., the "contracted" configuration of the fluid container 400).

This operating state can be used to release the fluid and reduce the fluid pressure in the fluid container 400 (e.g., the "contracted" configuration of the fluid container 400).

[0114] Operating state 5 (e.g., rotating the valve stem 910 60 degrees clockwise from operating state 4) is also the "live" state that moves fluid from the fluid container 400 to the foot support bladder 200. It is also the "live" state that moves fluid from the fluid container 400 to the foot support bladder 200. In operating state 5, fluid passes through the system (e.g., from fluid container 400 through manifold 8 00 through fluid transfer system 900A and back through manifold 800), and extends to foot support bladder 200. Refer to FIG. 30F. This operating state can be used to increase the fluid pressure in foot support bladder 200 by moving fluid from fluid container 400 into foot support bladder 200 (e.g., the "inflated" configuration of foot support bladder 200). This operating state allows the fluid pressure in foot support bladder 200 to be changed without the user having to take one or more steps to activate pumps 600H, 600F (e.g., when the user is standing still, sitting still, and / or resting their feet). As an example, large pressure spikes resulting from a wearer taking a step landing or jumping are blocked from direct fluid communication with foot support bladder 200 during this operating state (e.g., because fluid lines 606 from foot actuation pumps (s) 600H, 600F are closed), improving control and allowing fine-tuning of pressure changes in foot support bladder 200. Operating state 6 (e.g., rotating valve stem 910 60 degrees clockwise from operating state 5) is a "pumping" state that pumps fluid from a pump(s) (or other fluid source) into fluid container 400. In operating state 6, fluid passes through the system (e.g., from pumps 600H, 600F through manifold 800, through fluid transfer system 900A, back through manifold 800), and into fluid container 400. Refer to FIG. 30 G. This operating state rapidly and / or directly increases the fluid pressure in fluid container 400.

[0115] through manifold 800, through fluid transfer system 900A, back through manifold 800), and enters fluid container 400. This operating state rapidly and / or directly increases the fluid pressure in fluid container 400. that can be used to cause (e.g., the "inflated" configuration of the fluid container 400).

[0116] According to aspects of the present technology, some pressure sensing algorithms and methods use the operating state to determine, in addition to pressure sensing in the foot support bladder 200 and / or in the fluid container 400, sensor inputs may be relied upon. By way of example, data from an accelerometer, a foot force sensor, and / or speed, and / or distance monitor may be used to determine whether the pressure increase in the foot support bladder 20 0 should be achieved by operating state 2 (using fluid transferred from the foot actuating pumps 600H, 600F), or whether it should be achieved by operating state 5 (using fluid transferred from the fluid container 400). By way of example, when the user is moving relatively slowly, transfer by operating state 2 may be desirable, especially if the fluid container 400 is at a relatively low pressure. However, when the user is moving quickly and / or applying a strong contact force to the foot pumps 600H, 600F, operating state 5 may be preferred (e.g., to produce a more uniform fluid flow without pressure spikes due to contact of the sole with the ground). In addition, or alternatively, data from an accelerometer, a foot force sensor, and / or speed, and / or distance monitor may be used to automatically change the operating state , for example, to increase or decrease the foot support pressure in the foot support bladder according to the exercise speed, contact force, etc. Further, in addition, or alternatively, in accordance with the present technology, in at least some system and method embodiments, the system determines how the user moves (e.g., tends to run or exercise at a particular time of day, tends to run on a particular type of surface, speed . Further, in addition, or alternatively, and, in some system and method embodiments according to the present technology, the system determines how the user moves (e.g., tends to run or exercise at a particular time of day, tends to run on a particular type of surface, speed while changing (e.g., based on a training program) such as the tendency to run) "learning" (e.g., pattern identification) can be started, and based on this information, changes in the operating state can be predicted , and changes can be made to it to match the predicted changes in motion. Thus, the pressure change in the foot support system can better "in real time" with changes in the user's motion, and can seemingly synchronize in real time. Alternatively, when linked to a digital coaching system, the automatic (or system-generated) changes in the operating state are synchronized with the desired changes in motion received from the digital coaching system to match the desired performance , or can reduce the risk of injury, and thereby is also a communication system with the user. In addition, or alternatively, if desired, according to at least some aspects of the present technology, the system and method can determine and / or use sequential metrics regarding the user's contact force with the ground and / or various characteristics regarding the user's motion

[0117] (e.g., metrics regarding the user's running or other motion techniques). Such metrics can include one or more of the following: (a) the foot contact time per step (e.g., using the foot force signal such as the period when the vertical force applied by the foot is greater than 50 N); (b) the foot swing period per step (e.g., when the vertical force applied by the foot is less than 50 N, using the foot force signal such as the time per foot until that foot generates a force greater than 50 N again); (c) the step rhythm (e.g., the reciprocal of the total time of contact and swing for each foot, etc.). various step metrics can be determined and / or used. Such metrics can include one or more of the following: (a) the foot contact time per step (e.g., using the foot force signal such as the period when the vertical force applied by the foot is greater than 50 N); (b) the foot swing period per step (e.g., when the vertical force applied by the foot is less than 50 N, using the foot force signal such as the time per foot until that foot generates a force greater than 50 N again); (c) the step rhythm (e.g., the reciprocal of the total time of contact and swing for each foot, etc.). using the foot force s...
