[0196] Figure 26 Various examples of user devices for some applications according to the present invention are depicted. Detailed Implementation

[0197] Figures 1 to 2 This is a schematic diagram of a user device 100 shaped to define a plurality of chambers 28. For example, according to some applications of the invention, the user device 100 may be an insole device 20, a shoe, or a sock. The following text discusses... Figure 26 Further described, the user device 100 may be a footwear device 100a, a medical device 100b, a mattress device 100c, or a seat cushion 100d. By way of example, Figures 1 to 2 The features of the insole device 20 are described below. Typically, the insole device 20 treats a user, such as a patient 18, by selectively inflating multiple chambers 28 to facilitate walking. For example, the patient 18 may have lesions on the plantar surface of her foot, and the patient may wish to reduce the pressure applied to the lesions.

[0198] Typically, the insole device 20 includes an insole body 30 having a shape and size suitable for placement inside a user's shoe 32.

[0199] Circuit 34 is typically housed within control unit 26. Pump 38 is typically housed within control unit 26. Figure 3 Furthermore, the pump 38 can be attached by the user to the insole body 30, allowing the pump 38 and the rest of the control unit to be worn by the user while walking. For such applications, the control unit 26 is typically connected to, for example, Figure 1The control unit shown is smaller and is provided with a coupling mechanism (e.g., a clamp or snap) for attaching the control unit 26 to the shoe 32. Typically, the circuit 34 actuates the pump 38 when it is connected to the insole body 30 via a set of one or more tubes 39 to selectively inflate or deflate different chambers in the chamber 28 to at least two different corresponding pressures.

[0200] In some applications of the present invention, pump 38 includes a connection to pump port 44 ( Figure 3 The pump 38 uses a pump pressure sensor 40 and / or a flow sensor 41 (therefore, the pump port 44 is connected between the pump pressure sensor 40 and / or the flow sensor 41 and the selector valve 42A). The pump 38 uses pressure measurements from the pump pressure sensor 40 to regulate the inflation or deflation of the multiple chambers 28 during inflation or deflation.

[0201] Pump 38 is typically disconnectable from the insole body 30 by the user without affecting the corresponding pressure in the various chambers 28 of the user device 100, such as footwear device 100a, or insole body 30. For example, in some applications, the various chambers 28 are selectively inflated to at least two different corresponding pressures, and pump 38 is disconnectable from the insole body 30 by the user without deflating the chambers 28. Typically, circuitry 34 (or other circuitry, not shown) actuates at least one device pressure sensor, such as insole pressure sensor 36, to measure the pressure in the chambers 28 at least when pump 38 is not connected to the user device 100, such as footwear device 100a, or insole body 30. By way of illustration and not limitation, insole pressure sensor 36 may be integrated into insole body 30, disposed within control unit 26, or alternatively, connected to insole body 30 via leads and clipped or otherwise attached to shoe 32, for example, when user 18 is wearing the shoe.

[0202] In some applications, the insole device 20 communicates with an application on a user's mobile device 22, which in turn communicates with a corresponding application on a device of a medical professional 24. For example, the insole device 20 may send device diagnostic data and / or patient diagnostic data to the medical professional 24, and the medical professional 24 may send instructions to the insole device 20 (e.g., changing the inflation or deflation level of one or more chambers 28).

[0203] For some applications, user device 100 is footwear device 100a ( Figure 26Examples include the insole body 30, shoes (e.g., shoe 32), or socks. For some applications, the control unit 26, including circuitry 34 and pump 38, may be packaged separately from the user device 100 for commercial sale. Alternatively, for some applications, the user device 100 is sold commercially as a system along with the control unit 26.

[0204] For some applications, the user device 100 is a shoe, such as a user's shoe 32. Typically, a plurality of chambers 28 are provided in the inner part of the shoe, on which the user's foot rests when the shoe is in use. As described above, the pump 38: (a) can be connected to the shoe by the user so that the pump can be worn by the user while the user is walking, and (b) can be disconnected by the user from the shoe without affecting the corresponding pressure in the plurality of chambers 28.

[0205] Now refer to Figure 3 The illustration depicts a selection valve 42A disposed within the housing of a control unit 26 according to some applications of the invention. The selection valve 42A includes a pump port 44 and two or more auxiliary ports 45. A first auxiliary port 46 of the auxiliary ports is connected via a pipe 43 to a first chamber 47 in the chamber. Figure 1 The second additional port 48 in the additional port is connected to the second chamber 49 in the chamber via another tube in the tube 43. The tube 43 may be longer than the tube as depicted and converges into a plug 37, which can be connected to the user device 100, such as the footwear device 100a, such as the insole body 30 (e.g., as shown in the figure). Figure 1 (As shown in the diagram). Pump 38 is coupled to pump port 44. For example, circuitry 34 of the insole device 20 can actuate pump 38 by enabling selector valve 42A to inflate or deflate the first chamber 47 and the second chamber 49 in the following ways: (a) fluid communication between pump 38 and the first additional port 46, and at different times, (b) fluid communication between pump 38 and the second additional port 48. This selective control allows pump 38 to inflate the first chamber 47 and the second chamber 49 (and all other chambers) at different corresponding times. Typically, but not necessarily, pump 38 is coupled to pump port 44 of selector valve 42A via solenoid valve 35. Selector valve 42A may also include a release port 57.

[0206] Pump pressure sensor 40 is connected to pump 38 and pump port 44. Circuit 34 measures the pressure in the first chamber 47 and the second chamber 49 by enabling selection valve 42A in the following ways: (a) fluid communication between the first additional port 46 and pump pressure sensor 40, and at different times (b) fluid communication between the second additional port 48 and pump pressure sensor 40.

[0207] Now refer to Figure 4 and Figures 5A to 5B The illustration depicts different views of the selector valve 42B according to some applications of the invention. As described below, pressure is applied via conduit 50 to port 51, which is connected to an associated chamber 52 of the user device 100, such as footwear device 100a, such as the insole body 30. To allow air to move from pump 38 through selector valve 42B, a rotatable component of stepper motor 53 of selector valve 42B is rotated to align pump outlet pipe 56A with port 51. This allows air (or any other fluid) to move freely from pump 38 to port 51, to conduit 50, and then through pipe 43 in fluid communication with associated chamber 52, thereby aligning associated chamber 52 ( Figure 1 Inflation. Spring 55 facilitates maintaining an airtight seal between port 51 and the rotatable parts of stepper motor 53, and between port 51 and pump output pipe 56A, when port 51 and pump output pipe 56A are aligned. Ball bearing 60 at the base of the selector valve allows rotation with minimal friction.

[0208] Now refer to Figures 6 to 7B It depicts an alternative selection valve 42C for some applications according to the invention. For example... Figure 7A As shown, pump outlet pipe 56B allows air to move from pump 38 through selector valve 42C. Lateral port 70 transmits this pressure to chamber 75 of port 66 of selector valve 42C. An airtight seal provided by O-ring 54 surrounding a rod 71 passing through port 66 prevents air from moving from lateral port 70 through chamber 75 to pipe 43, and thereby prevents inflation of the associated chamber 72.

[0209] like Figure 7B As shown, in order to allow air to move from pump 38 through selector valve 42C, air moves through lateral port 70. The hermetic seal provided by O-ring 54 surrounding rod 71 is broken when a force is applied to rod 71 by piston 73 coupled to rotatable arm 68. This allows air to move from pump 38 through pump outlet pipe 56B through pipe 43, thereby inflating the associated chamber 72.

[0210] Now refer to Figure 8This describes a user device 100, such as a footwear device 100a, or an insole body 30, according to some applications of the invention. Typically, the insole body 30 includes an elastic base 74 on which chambers 28 are disposed. Typically, when no force is applied to the elastic base 74, the height of the upper surface of the elastic base 74 below a first chamber is higher than the height of the upper surface of the elastic base 74 below a second chamber. This height difference allows the chambers 28 to use less air (or any other fluid) and inflate to their proper operating height in a shorter time compared to when the upper surface of the base has a uniform height. Furthermore, even when none of the chambers in the insole body 30 are inflated, a default support profile is provided to the user's foot.

[0211] Typically, the insole device 20 includes an inlet 76 to which a positive or negative pressure source (e.g., a pump 38) can be connected to inflate or deflate a corresponding chamber among the plurality of chambers 28. The inlet 76 is typically connected to the inlet mentioned above. Figure 3 , Figure 4 , Figures 5A to 5B , Figure 6 and Figures 7A to 7B The described selector valves are compatible with 42A, 42B, and 42C.

[0212] Now refer to Figures 9A to 9B It depicts the inflation of multiple chambers 28 in some applications according to the present invention. Figure 9A Depicting in Figure 8 The cross-section is marked IXA. The inner bottom device 20 includes multiple flow control elements, such as valves 78, each of which is in fluid communication with a corresponding one of the multiple chambers 28. Valve 78 is typically, but not necessarily, a duckbill valve and allows air (or any other fluid) to enter via pipe 82 through the open side 80 and inflate the associated multiple chambers 28. When pipe 82 is removed from valve 78, the downstream end 84 of the valve remains closed, thereby maintaining pressure in the associated chamber 28.

[0213] Figure 10 This is a schematic diagram depicting an assembly of a valve 78 disposed in an inlet 76 according to some applications of the present invention. As shown, the valve 78 is connected from the center direction to the chamber 28 (e.g., Figures 9A to 9B As shown in the figure.

[0214] Figures 11A to 11B This is a schematic diagram depicting components of a valve 78 according to some applications of the present invention. The user device 100, such as a footwear device 100a, or the lower surface 86 of the insole body 30 facing downwards, faces the sole 88 of the shoe 32. Figure 1 ). Figure 11BOne of these valves 78 is shown, which is in fluid communication with chamber 47 via a downward-facing inlet, and which can be positioned in fluid communication with pump 38 when the inner bottom body 30 is connected to pump port 90. A plurality of pipes 82 of pump port 90 can be connected via corresponding valves in the valves 78 to corresponding chambers 28 on the inner bottom body 30 to facilitate inflation of chambers 28 using the techniques described above.

[0215] Now refer to Figures 12A to 12D , Figures 13A to 13B and Figure 14 It depicts a user device 100, such as a footwear device 100a, such as an insole body 30, for some applications according to the invention, and a lock 102 for controlling fluid communication with a plurality of chambers 28. Typically, the user device 100 has a plurality of tubes 104, each tube 104 being in fluid communication with a corresponding one of the plurality of chambers 28. Each tube 104 has an inlet 106 to which a positive or negative pressure source, such as a pump 38, can be coupled to selectively inflate or deflate the plurality of chambers to at least two different corresponding pressures.

[0216] For some applications, lock 102 has lock housing 110. Lock housing 110 has multiple channels, and tubes 104 are arranged through multiple channels such that each inlet 106 of a corresponding tube 104 is located near the opening 114 of the corresponding channel in lock housing 110 (e.g., Figures 13A to 13B and Figure 14 (As shown). Opening 114 in Figure 12A The diagram shows two rows of small holes in the lock housing 110, each opening allowing fluid to enter a corresponding inlet 106 of the tube 104. The pump connector 108 includes a corresponding plurality of pump tubes 112, such as... Figure 2 The pipe 39 shown is the pipe 43 of the selector valve. Each pump pipe 112 has an interface end 116, such as a rigid interface end, protruding from the pump connector 108. When the pump connector 108 is coupled to the lock housing 110 (by the... Figures 12A to 12B As depicted in the transition), each interface end 116 of the corresponding pump tube 112 is inserted into the corresponding opening 114, thereby establishing fluid communication between (i) the interface end 116 of each pump tube 112 and (ii) the corresponding inlet 106 of each tube 104. It should be noted that inserting each interface end 116 into the corresponding opening 114 creates a pneumatic seal between the interface end 116 and the opening 114, preventing air leakage from the pump tube 112 into the inlet 106 of the tube 104 (or from the inlet 106 of the tube 104 into the pump tube 112).

[0217] Lock 102 is positioned within lock housing 110 and arranged such that (a) when lock 102 is in the open position (e.g.) Figure 13A(a) When shown, there is fluid communication between the inlet 106 of each pipe 104 and a corresponding one of the plurality of chambers 28, and (b) when the lock 102 is in the closed position (as shown) Figure 13B As shown, lock 102 blocks multiple pipes 104 such that there is no fluid communication between the inlet 106 of each pipe 104 and a corresponding one of the multiple chambers 28. For some applications, changing lock 102 from the open position to the closed position and vice versa can be performed using lock handle 118. Figure 12A , Figure 12B and Figure 12D In the diagram, the lock handle 118 is shown in the position corresponding to the lock 102 being in the closed position, i.e., the sealing tube 104. Figure 12C In the diagram, the lock handle 118 is shown in a position corresponding to the lock 102 being in the open position, that is, allowing fluid communication between the inlet 106 of each pipe 104 and a corresponding one of the plurality of chambers 28.

[0218] For some applications, examples of sequences for selective inflation of chamber 28 are provided by Figures 12A to 12D It is expressed as follows:

[0219] • exist Figure 12A In this case, multiple chambers 28 are not inflated, lock 102 is in the closed position (as indicated by the position of lock handle 118), and pump connector 108 is disconnected from lock housing 110.

[0220] • Figure 12B A pump connector 108 is shown attached to the lock housing 110 when the lock 102 is held in the closed position. Figure 13B Is in Figure 12B The cross-section of the pump connector 108 and the lock housing 110 in the state shown is illustrated.

[0221] • Figure 12C It is shown that lock 102 has been changed to the open position to allow fluid communication with the multiple chambers 28. Pump 38 is then actuated to selectively inflate some of the chambers 28. Figure 12C In the specific example shown, most of the chambers 28 are inflated, except for a small area 120 that may correspond to the location of the lesion on the user's foot. Inflating the chambers 28 surrounding the lesion provides protection for the lesion and comfort for the user while walking. Figure 13A Is in Figure 12C The cross-section of the pump connector 108 and the lock housing 110 in the state shown is illustrated. Figure 13A Arrow 122 in the cross-section shown depicts the direction of airflow from pump 38 when chamber 28 is inflated.

[0222] • Figure 12DThis shows that lock 102 has been changed back to the closed position, thereby sealing pipe 104. Pump connector 108 can then be disconnected from lock housing 110. Figure 14 (as depicted in the text), without affecting the corresponding pressure in the multiple chambers 28.

[0223] It should be noted that, Figures 12A to 12D The inner insole body is depicted only as an example. As described above, and as referenced below. Figure 26 Furthermore, the user device 100 may be a footwear device 100a (e.g., a shoe, an insole body shaped and sized for placement in a shoe, or a sock), a medical device 100b (e.g., a bandage, cast, or wound dressing device), a mattress device 100c (e.g., a mattress or mattress cover), or a seat cushion 100d (e.g., a chair cushion or bicycle seat). The features of the lock 102 and pump connector 108 described above can be used with any of the user devices described above.

[0224] Now refer to Figures 15A to 15D , Figures 16A to 16B and Figure 17 It depicts a user device 100, such as a footwear device 100a, such as an insole body 30, for some applications according to the invention, and a lock 102 for controlling fluid communication with a plurality of chambers 28. For some applications of the invention, the inflation mechanism described herein is adapted to allow controlled deflation of the aforementioned chambers, rather than controlled inflation of the chambers. For some applications, such as in… Figure 15A In the example shown, each chamber 28 has the following shape: (a) expands when the air pressure in the chamber 28 is atmospheric pressure, and (b) retracts when the air pressure in the chamber 28 is below atmospheric pressure.

[0225] Similar to the reference above Figures 12A to 12D As described, the user device 100, such as footwear device 100a, such as insole body 30, includes a plurality of tubes 104 (in... Figures 16A to 16B and Figure 17 As shown, each tube 104 is in fluid communication with a corresponding one of the plurality of chambers 28. Each tube 104 has an inlet 106 to which a suction source can be coupled to provide fluid communication between the inlet 106 and the suction source. For some applications, the suction source may be a pump, such as pump 38. When the pump is coupled to the user device 100, the pump can apply suction to at least one of the plurality of chambers 28.

[0226] For reference Figures 12A to 12B , Figures 13A to 13B and Figure 14The features of the lock 102, lock housing 110, pump connector 108 and lock handle 118 described herein apply regardless of whether (i) chamber 28 is initially started and inflated in the retracted state or (ii) chamber 28 is initially started and retracted in the expanded state.

[0227] For some applications, examples of sequences that selectively apply suction to deflate chamber 28 are provided by Figures 15A to 15D It is expressed as follows:

[0228] • exist Figure 15A In this configuration, multiple chambers 28 are in an expanded state, lock 102 is in a closed position (as indicated by the position of lock handle 118), and pump connector 108 is disconnected from lock housing 110.

[0229] • Figure 15B A pump connector 108 is shown attached to the lock housing 110 when the lock 102 is held in the closed position. Figure 16B Is in Figure 15B The cross-section of the pump connector 108 and the lock housing 110 in the state shown is illustrated.

[0230] • Figure 15C It is shown that lock 102 has been changed to the open position to allow fluid communication with the multiple chambers 28. Pump 38 is then actuated to apply suction to selectively vent some of the chambers 28. Figure 15C In the specific example shown, most of the chambers 28 remain in their expanded state, except for a small area 120 that may correspond to the location of a lesion on the user's foot. Deflating only the chambers 28 located in the area corresponding to the lesion provides protection against the lesion and comfort for the user while walking. Figure 16A Is in Figure 15C The cross-section of the pump connector 108 and the lock housing 110 in the state shown is illustrated. Figure 16A Arrow 124 in the cross-section shown depicts the direction of the airflow from pump 38 when suction is applied to vent chamber 28.

[0231] • Figure 15D This shows that lock 102 has been changed back to the closed position, thereby sealing pipe 104. Then, pump connector 108 can connect to lock housing 110 ( Figure 14 (As depicted in the text) disconnect the connection without affecting the corresponding pressure in the multiple chambers 28.

[0232] It should be noted that, Figures 15A to 15D The inner insole body is depicted only as an example. As described above, and as referenced below. Figure 26As further described, the user device 100 may be a footwear device 100a (e.g., a shoe, an insole body shaped and sized to be placed in a shoe, or a sock), a medical device 100b (e.g., a plaster cast or bandage for reducing pressure on a lesion), a mattress device 100c (e.g., a mattress or mattress cover for reducing pressure on a bedsore), or a seat cushion 100d (e.g., a chair cushion or bicycle seat for reducing pressure on a lesion).

[0233] Now refer to Figures 18A to 18B 19A to Figure 19B and Figure 20 It depicts a user device 100, such as a footwear device 100a, or an insole body 30, for some applications according to the invention, wherein a selector valve 126 is integrated into the user device 100. For some applications, the selector valve is part of an external pumping device (e.g., Figure 3 , Figure 4 , Figures 5A to 5B , Figure 6 and Figures 7A to 7B As an alternative to the one shown, the selector valve 126 is integrated into the user device 100, for example, at least partially disposed within the user device 100, and arranged to engage with an external pressure device 128, which typically includes a pump 130 and a motor 132. The advantage of integrating the selector valve into the user device 100 is that it simplifies the connection between the pressure device 128 and the user device 100. Instead of connecting multiple pipes to multiple corresponding openings in the user device 100 (e.g., as described above with respect to pump connector 108), the selector valve 126 has a pump port 134 to which the pressure device 128 can be coupled, for example, the pump 130 of the pressure device 128 can be coupled to the pump port 134. Typically, the pump 130 has a single output pipe 136 coupled to the pump port 134.

[0234] For some applications, the selector valve 126 has two or more interface ports 138, each having a corresponding inlet 140 and a corresponding outlet 142. The outlet 142 of the first interface port 138 is, for example, via pipe 144 ( Figure 19A The first chamber of chamber 28 is in fluid communication with the second chamber 28, and the outlet 142 of the second interface port 138 is in fluid communication with the second chamber of chamber 28. Typically, the selector valve 126 has an interface port 138 corresponding to each chamber of chamber 28 in the user device 100. The inlet 140 of each interface port 138 is in fluid communication with the pump port 134. For some applications, and as shown, all inlets of inlet 140 lead to a common space 146 in fluid communication with the pump port 134.

[0235] A pressing surface 148 is arranged within the selector valve 126 such that (a) in a first position of the pressing surface 148, the pressing surface 148 provides fluid communication between the pump port 134 and the inlet 140 of the first interface port in the interface port 138, and restricts fluid communication between the pump port 134 and the outlet 142 of the second interface port in the interface port 138, and at different times, (b) in a second position of the pressing surface 148, the pressing surface 148 provides fluid communication between the pump port 134 and the outlet 142 of the second interface port in the interface port 138, and restricts fluid communication between the pump port 134 and the inlet 140 of the first interface port in the interface port 138. Typically, in each position of the pressing surface 148, the pressing surface 148 restricts fluid communication between the pump port 134 and all outlets of the interface port 138 except for one outlet of the outlet 142, such that fluid communication between the pump port 134 and each chamber 28 can be actuated one at a time.

[0236] In addition, a "blank" position is typically provided in which the pressing surface 148 can be positioned such that it restricts fluid communication between the pump port 134 and all outlets 142 of the interface port 138. That is, when the pressing surface 148 is in the "blank" position, fluid pathways to all chambers 28 are blocked, thereby allowing the pressure device 128 to be disconnected from the user device 100 without affecting the corresponding pressure within the chambers 28.

[0237] By way of examples Figure 20 A pressing surface 148 is shown arranged to seal the interface port 138 at a location between the inlet 140 and the outlet 142, thereby restricting fluid communication with the chamber 28. Figure 20 The enlarged view on the left shows the pressing surface 148 of the sealing interface port 138. A recess 150 is present at a location on the pressing surface 148. In each corresponding location on the pressing surface 148, the recess 150 is aligned with a given interface port 138 or a "blank" location. When the recess 150 is aligned with a given interface port 138, that interface port 138 is not sealed by the pressing surface 148, thus allowing fluid communication between the pump port 134 and the outlet 142 of that interface port 138. Figure 20 The enlarged view on the right shows the recess 150 that enables fluid communication between the pump port 134 and the outlet 142 of the given interface port 138.

[0238] For some applications, such as in Figures 19A to 19B and Figure 20The application illustrated by way of example shows that the pressing surface 148 is a rotating pressing surface 148, and the interface port 138 is positioned in a circular manner around the edge of the pressing surface 148. In this example, the position of the pressing surface 148 described above refers to the rotational position of the pressing surface 148.

[0239] For some applications, the pressure device 128 includes a pump 130 that can be coupled to a pump port 134, a motor 132 that can be actuated to change the position of the pressing surface 148, and a control circuit 152. For some applications, the selector valve 126 has a motor port 154 to which the motor 132 can be coupled, for example, via a motor protrusion 156. When the pump 130 is coupled to the pump port 134, the control circuit 152 can actuate the pump 130 to inflate or deflate the first and second chambers 28, for example, selectively inflate or deflate any chamber 28 of the user device 100:

[0240] (i) Actuating motor 132 to position pressing surface 148 in a first position, and when pressing surface 148 is in the first position, actuating pump 130 to apply positive or negative pressure to inflate or deflate the first chamber in chamber 28 to a first pressure, and subsequently

[0241] (ii) Actuate motor 132 to position pressing surface 148 in a second position, and when pressing surface 148 is in the second position, actuate pump 130 to apply positive or negative pressure to inflate or deflate the second chamber in chamber 28 to a second pressure.

[0242] In this way, the pressing surface 148 can be moved sequentially through various positions corresponding to each interface port 138 so as to selectively inflate, deflate, or skip each chamber 28 (according to the user’s specific needs) until the pressing surface 148 reaches the “blank” position, at which point the pressure device 128 can be disconnected from the user device 100 without affecting the corresponding pressure in the multiple chambers 28.

[0243] For some applications, pressure device 128 may be packaged separately from user device 100 for commercial sale. Alternatively, for some applications, user device 100 is sold commercially as a system together with pressure device 128.

[0244] Now refer to Figures 21A to 21B , Figure 22 , Figure 23 , Figures 24A to 24C and Figures 25A to 25C describes a process for manufacturing a user device 100, such as a footwear device 100a, or an insole body 30, according to some applications of the invention. For some applications, the user device 100 is manufactured such that a single-piece elastomer 158 is shaped to define a plurality of selectively inflatable or deflated chambers 28. Each chamber 28 is shaped to define an orifice 160, such that the single-piece elastomer 158 forms (i) the orifice 160, (ii) an orifice end wall 162 of each chamber 28, and (iii) a flexible wall 164, such as an expandable wall, opposite the orifice end wall of each chamber 28. For some applications, the advantage of forming the chambers 28 by a single-piece elastomer is that when the flexible wall 164 moves (e.g., stretches) during inflation or deflation of the chambers 28, the single-piece elastomer abuts itself rather than, for example, against a seam.

[0245] Typically, a plurality of plugs 166 are provided in the orifices 160 of the plurality of chambers 28 respectively. Each plug 166 includes a corresponding tube 144, such that each tube 144 (e.g., as...) Figure 19A The tube 144 is in fluid communication with the corresponding chamber 28. Each tube 144 has an inlet 168 to which a positive or negative pressure source, such as a pump, can be connected to selectively inflate or deflate the chamber 28 to at least two different corresponding pressures.

[0246] For some applications, each plug 166 has a plug head 170 disposed against the inner surface 172 of the orifice end wall 162 of each corresponding chamber 28, such that when a given chamber 28 is inflated or deflated, movement of the orifice end wall 162 toward the flexible wall 164 opposite the orifice end wall 162 is inhibited by the plug head 170. For some applications, the gap between each plug 166 and the orifice 160 of the chamber 28 is created by placing a sealing material 174, which hardens within the orifice 160 after the plug 166 is disposed in the orifice 160. Figure 24B and Figure 25B As shown, the sealing material 174 surrounds the tube 144 of each plug 166.

[0247] For some applications, to further suppress movement of the orifice end wall 162 during inflation or deflation of the chamber 28, corresponding supports 176 are disposed against the outer surface 178 of the orifice end wall 162 of each chamber 28, thereby surrounding the orifice 160. When a given chamber is inflated or deflated, movement of the orifice end wall 162 away from the flexible wall 164 opposite to the orifice end wall 162 is suppressed by the supports 176. For some applications, to secure the supports 176 in place, additional sealing material 174 is placed between the orifice 160 and the supports 176 on the outer surface 178 of the orifice end wall 162.

[0248] Alternatively or otherwise, for some applications, the orifice end wall 162 is thicker than the flexible wall 164, such that when a given chamber is filled or deflated, the thickness of the orifice end wall 162 inhibits the movement of the orifice end wall 162 of the chamber 28.

[0249] Figures 24A to 24B The user device 100 is depicted by way of example in a retracted state, specifically in chamber 28. As described above, a monolithic elastomer 158 forms an orifice 160 and an orifice end wall 162 and a flexible wall 164 of chamber 28. A plug 166 is shown disposed within chamber 28, a support 176 is shown supporting the outer surface 178 of the orifice end wall 162, and a sealing material 174 can be seen sealing the gap between the plug 166 and the orifice 160, and holding the support 176 in place. Figures 25A to 25B The user device 100 is depicted by way of example, showing a single chamber 28 in an expanded state, such as an inflated state, of chamber 28.

[0250] Referring to Figures 21 to 25, for some applications, the method of manufacturing the user device 100, such as the footwear device 100a, or the insole body 30, is as follows:

[0251] • A first plate 180 is placed near a second plate 182, the first plate 180 being shaped to define a plurality of holes 184. A plurality of removable inserts 186 are provided in each hole 184. Each insert 186 is shaped to have a head 188, which is positioned on the top side 190 of the first plate 180 when the insert 186 is placed in the hole 184.

[0252] • A liquid elastomer 158 is injected between the first plate 180 and the second plate 182 such that the liquid elastomer 158 surrounds the head 188 of each removable insert 186 and is sealed between the first plate 180 and the second plate 182 as the elastomer 158 solidifies. Figure 21A An exploded view is shown of the insert 186 and the elastomer 158 corresponding to the hole 184 therein, which is enclosed between the first plate and the second plate.

[0253] • Once the elastomer 158 has cured, the second plate 182 is removed from the first plate 180. Then, the cured elastomer is removed from the first plate 180, thereby pulling the removable insert 186 out of the corresponding hole 184 in the first plate 180.

[0254] • Then, the removable insert 186 is removed from the cured elastomer 158, such that a corresponding chamber 28 is defined in the cured elastomer at the location where the elastomer originally surrounded each head in the head 188. Each chamber 28 is shaped to define (i) an orifice 160, (ii) an orifice end wall 162, and (iii) a flexible wall 164 opposite to the orifice end wall 162. Figure 21B The illustration depicts the removal of the insert 186 from the corresponding chamber 28 after the cured elastomer 158 has been removed from the first plate 180.

[0255] • Then, insert plug 166 into each of the chambers 28 as described above. Figure 23 It depicts the insertion of plug 166 into the corresponding chamber 28.

[0256] • As described above, the gap between each plug 166 and the orifice 160 is sealed, and a support 176 is optionally attached. Figure 24C An example of a user device 100, such as a footwear device 100a, or an insole body 30, is shown, wherein a plug 166 is disposed in each chamber 28, and a support 176 is disposed around each opening 160. It should be noted that, as Figure 24C As shown, plug 166 is positioned in chamber 28 such that each tube 144 points in the general direction of the side gap 192 in the cured elastomer 158. This allows the tubes 144 to converge together in a common direction. For example, as described above, all tubes 144 can be connected to a common selector valve or lock housing.

[0257] For some applications, Figure 22 An alternative method of manufacturing the user device 100 is illustrated. For some applications, instead of using a removable insert 186, a first plate 180' is shaped to define a plurality of heads 194, each of which is disposed on a corresponding post 196 projecting from the top side portion 190' of the first plate 180'. A liquid elastomer 158 is injected between the first plate 180' and the second plate 182 such that the liquid elastomer surrounds each head 194 and each post 196, and such that the liquid elastomer is enclosed between the first and second plates. Once the elastomer 158 has cured, the second plate 182 is removed from the first plate 180', and then the cured elastomer 158 is removed from the first plate 180', such that a corresponding chamber 28 is defined in the cured elastomer at the location where the elastomer originally surrounded each of the heads 194.
