[0002] Various shoe-type sensors have been proposed to monitor various conditions. Brown has developed a "sensor shoe for monitoring foot conditions." hoe for monitoring the condition of a fo In Patent Document 1, entitled "Sensor for a Footwear-type Sensor," several examples of shoe-type sensors are proposed. The foot force sensor is an insulator made of a layer of a relatively thin, flat, flexible, and resilient dielectric material. The foot force sensor detects the force of the foot as the compressive force applied increases. The conductive interconnect means may include a conductive interconnect means having an electrical resistance that is reduced so that the conductive interconnect means is electrically conductive.

The sensors are arranged in diagonal pairs to detect both values. It can contain a circuit of four piezoresistors, and the increase in pressure in the hydrocell When a resistor is connected to a resistor, the resistance of one pair increases and the resistance of the second pair decreases, causing all resistors to The resistance of the body increases or decreases in response to increasing or decreasing temperatures within the hydrocell, respectively. The output from the circuit can indicate the change in pressure and temperature. The grid array sensor detects local pressure changes on the sole of the foot by measuring the resistance between conductors at the location of increased pressure. He states that this can be detected by reducing the resistance between the conductors. This can be detected by the processor and the processor will then ramp up The pressure sensor can provide an indication of the pressure status.

[0013] The drawings are not necessarily drawn to scale, and in the drawings like reference numerals refer to: Similar components may be illustrated in different figures. Similar components may have different subscripts. Reference numerals may represent different instances of similar elements. By way of example, and not limitation, various embodiments discussed in this document are shown and described in It shows.

[0014] The headings provided herein are for convenience only and are not necessarily intended to be used. It does not affect the scope or meaning of the terms used. The following is an electric racing engine, midsole plate, and platform Automated footwear platform that includes various other components of the Many of the disclosures are based on the concept of an electric racing engine. While the focus is on the gin, many of the mechanical aspects of the designs discussed provide additional functionality. Human-powered racing engines or other motorized racing engines with greater or lesser power Therefore, the "Automated Footwear Platform" The term "automated," as used in the "Automated Program" means something that operates without user input. It is not intended to cover only systems that operate The term "laced footwear platform" refers to the fastening of footwear laces. A variety of powered and human-powered mechanisms for lifting or holding systems, This includes dynamically actuated mechanisms as well as human actuated mechanisms.

[0015] FIG. 1 illustrates a powered lacing system for footwear according to some exemplary embodiments. FIG. 2 is an exploded view of the components of the system. The system 1 includes a racing engine 10, a lid 20, an actuator 30, and a midsole. The plate 40, the midsole 50, and the outsole 60 are included. The basic assembly sequence of the components of the racing footwear platform is shown below. As shown in the figure, the motorized lacing system 1 has a midsole plate 40 The actuator 30 is then fixed in the outsole 6. The midsole play is located opposite the interface buttons that can be embedded in the The racing engine 10 is then inserted into the opening in the outer part of the mid-seat. In the example, the lacing system 1 is The continuous loop of cable is inserted under the lacing element. The spool is aligned with the engine 10 (discussed below). Finally, the lid 20 The midsole plate 40 is inserted into the groove and locked into a closed position. The lid 20 is latched into a recess in the sole plate 40. It is possible to capture the engine 10 and also the arrangement of the lacing cables during operation. It is possible to help maintain

[0016] In an example, a footwear article or motorized lacing system 1 may monitor foot presence characteristics. or includes one or more sensors capable of monitoring or determining The device is configured to interface with one or more sensors. or a plurality of foot presence sensors based on information from the foot presence sensor. The hardware can be configured to perform a variety of functions. For example, a foot presence sensor , a binary as to whether the foot is present or absent in the footwear. The binary signal from the foot presence sensor may be configured to provide information indicating whether a foot is present. If the driver indicates that the vehicle is in a racing position, the motorized racing system 1 may be activated. Automatically tighten or loosen hardware lacing cables (i.e. In an example, the article of footwear includes a processor circuit, The processor circuitry is capable of receiving or interpreting signals from the foot presence sensors. The processor circuit may optionally be installed in or on the racing engine 10. The support 10 may be embedded, for example, in the sole of an article of footwear.

[0017] In one example, a foot presence sensor may be used to measure foot position information as the foot enters the footwear. The motorized lacing system 1 can be configured to provide information about the foot when the foot is in the footwear. The footwear may be appropriately positioned in the footwear, for example with respect to all or part of the sole of the footwear article. and actuate it, for example to tighten a lacing cable, only when it is retracted. A foot presence sensor that senses information about foot movement or position can be used to detect when a foot is moving, e.g. Contained completely or partially in relation to the footwear mechanism or in relation to some other feature of the footwear article. The automatic lacing procedure uses the information from the sensors to provide information about whether the foot is It can be paused or delayed until it indicates it is in the correct position.

[0018] In one example, a foot presence sensor provides information regarding the relative position of the foot within the footwear. For example, a foot presence sensor may be configured to provide a good indication of a foot with footwear. Whether or not the shoe has a proper "fit" can be determined by, for example, the arch, heel, toe, or other components of the foot. A frame configured to receive one or more of such foot components, for example. and configured to sense by determining a relative position of the In one example, the foot presence sensor detects the position of the foot or foot component relative to a reference. For example, the loosening of the lacing cables over time, or the natural expansion and contraction of the foot itself. The device can be configured to detect whether the change occurs due to shrinkage.

[0019] In some examples, the foot presence sensor may be an electrical, magnetic, thermal, capacitive, pressure, optical, or other sensor. The device may include a sensor device adapted to sense or receive information regarding the presence of a body. For example, the electrical sensor may be configured to measure impedance characteristics between at least two electrodes. The impedance sensor may be configured to measure the position of the body such as the foot. When near or adjacent to the electrical sensor, the electrical sensor can provide a sensor signal having a first value. When the foot is moved away from the electrode, the electrical sensor generates a sensor signal having a different second value. For example, the first impedance value may be provided for an empty footwear state. A second, smaller impedance value can be associated with an occupied foot. In one example, the electrical sensor may be located within the footwear. If a bar is present or is likely to be present, a binary signal or It can be configured to provide an interrupt signal, e.g., when a measured electrical characteristic ( For example, capacitance, resistance, impedance, etc.) exceeds a certain threshold or reference value. , a binary signal or an interrupt signal can be asserted.

[0020] The electrical sensor includes an AC signal generator circuit and a device that transmits or receives, for example, radio frequency information. The device may include an antenna configured to: Receive and measure one or more electrical signal characteristics, such as impedance, frequency, or signal amplitude. The received signal strength indicator (RSI) can be analyzed to determine whether a body is present. (RSSI: received signal strength indicator) is the power level of a received wireless signal. For example, the change in RSSI relative to some baseline or reference value. can be used to identify the presence or absence of a body. In one example, e.g., 2.4 GHz, 3. One or more of the following bands: 6GHz, 4.9GHz, 5GHz, and 5.9GHz iFi frequencies can be used. In one example, frequencies in the kilohertz range, e.g., about 400 kHz. In some instances, the change in power signal may be in milliwatts or microwatts. It can be detected in the range of 100m.

[0021] The foot presence sensor may include a magnetic sensor. The first magnetic sensor may include a magnet and a magnetometer. Alternatively, the magnetometer and a material that can be sensed by the magnetometer may be included. Thus, the magnetometer can be placed on or near the racing engine 10. Other materials that cause a response by the gauge may be located away from the racing engine 10, e.g. For example, a second sole, or an insole configured to be worn over the outsole 60. In some instances, the magnets may be disposed within a foam or other compressible material of the second sole. The sensor is embedded in a material that can be used for a second time. When the sole of the sensor is pressed down, the corresponding change in the magnet's position relative to the magnetometer is sensed and the sensor This can be reported via a signal.

[0022] The second magnetic sensor is adapted to sense changes or interference in a magnetic field (e.g., via the Hall effect). When the body is in the vicinity of the second magnetic sensor, The sensor can generate a signal indicative of a change to the surrounding magnetic field. The magnetic sensor is a Hall effect sensor that changes its voltage output signal in response to changes in the detected magnetic field. The voltage change of the output signal may be a function of, for example, the current in a conductor and a voltage perpendicular to the current. Due to the production of a voltage difference across an electrical signal conductor, such as across a magnetic field It could be.

[0023] In one example, the second magnetic sensor is configured to receive an electromagnetic field signal from the body. For example, Varshavsky et al. Devices, systems and methods for security using ms and methods for security using magnet U.S. Patent No. 6,333,663 entitled "Crystalline Field Based Identification (Crystalline Field Based Identification)" No. 8,752,200 teaches the use of the body's unique electromagnetic signature for authentication. In one example, a magnetic sensor in a footwear product detects whether the current wearer is wearing a shoe. Authenticating or verifying the ownership via a detected electromagnetic signature, e.g., one of the owners or multiple specified lacing preferences (e.g., lacing profile), It can be used to authenticate or verify that the product should be automatically laced.

[0024] In one example, the foot presence sensor detects a change in temperature in or near a portion of the footwear. The article of footwear includes a thermal sensor configured to sense when the wearer's foot enters the article of footwear. The internal temperature of the product may change if the wearer's own body temperature differs from the temperature surrounding the footwear product. Therefore, the thermal sensor provides an indication of whether or not a foot may be present based on temperature changes. can be provided.

[0025] In one example, the foot presence sensor is a capacitive sensor configured to sense a change in capacitance. The capacitive sensor may include one plate or electrode, or the capacitive sensor may include a The capacitive foot presence sensor may include a multi-plate or multi-electrode configuration. Reveal.

[0026] In one example, the foot presence sensor includes an optical sensor, the optical sensor having a line of sight, e.g. It can be configured to determine whether the footwear cavity is interrupted, such as between the sides of the footwear cavity. In one example, the optical sensor is covered by the foot when the foot is inserted into the footwear. The sensor indicates a change in the sensed light conditions to indicate the presence of a foot. Or it may provide an indication of the location.

[0027] In one example, the electric racing engine of FIG. 1 includes a midsole 50 and a racing The system 1 includes a midsole and / or a racing engine 1 0 to improve comfort or fit for the wearer of the footwear. The straps or laces may be arranged, for example, around the foot when the product is worn. The Racing Engine 10 can be adjusted to adjust the tightness or looseness characteristics of the product. That is, the straps or laces can be attached to the motor of the racing engine 10. It can be configured to move between a tightened and a relaxed position in response to activity. In this study, System 1 uses a ferromagnetic material installed in the product and an insulator that is attached to the shoe by the foot when the shoe is worn. A small sensor configured to sense a change in position of the ferromagnetic body in response to the sole being compressed. The ferromagnetic material may be placed, for example, in or on the insole, and may be detected by the wearer. When the wearer steps or stands, the compressive force of the wearer's foot against the insole is transferred to the ferromagnetic material. The object, referred to herein as a ferromagnetic object, is one that is detectable by a sensor or whose movement is The lacing material may be any material that can be detected by the sensor. The engine 10 can be connected to a sensor, and the racing engine 10 can be connected to a strap or a race The sensor is configured to respond to sensed changes in the position of the ferromagnetic body by adjusting the tension of the wire. can.

[0028] The sensor may include a magnetometer configured to sense changes in a magnetic field. The change is at least partially in response to, for example, the movement of the footwear or the foot within the footwear. This may be due to a change in the position of the ferromagnet that has been moved. In one example, the ferromagnet and one of the magnetometers is substantially fixed relative to the housing or wall of the product, and the other of the ferromagnetic body and the magnetometer It is movable relative to the housing or walls of the product. For example, the ferromagnetic material may be placed in an insole. The magnetometer can be positioned in the midsole and moved in response to compressive foot forces. Or it can be virtually fixed inside a racing engine.

[0029] In some instances, information regarding the change in position of the ferromagnetic body can be sensed and used to inform the user of the product. It can be used to determine various properties. For example, information about a changing magnetic field can be used to determine the properties of a magnetic material. A large or rapid change in the magnetic field can be sensed by a magnetometer in response to the movement of This may indicate that magnetic objects are moving at high speeds or over long distances, and therefore may be harmful to the wearer. the person exerts substantial forces on the footwear, for example through running or jumping activities It shows that timing information about the sensed magnetic field or position change of the ferromagnetic body can be used to For example, to count steps or to determine how fast the wearer is moving (e.g. For example, when stride length information is known or recognizable, the timing of foot strike can be determined. It can be determined.

[0037] FIG. 2C illustrates various internal components of racing engine 10 according to an exemplary embodiment. In this example, the racing engine 10 includes a spool magnet 136, Ring seal 138, worm drive part 140, bushing 141, worm drive key 1 42, gear box 144, gear motor 145, motor encoder 146, motor Circuit board 147, worm gear 150, circuit board 160, motor header 161, It further includes a battery connection 162, and a wired charging header 163. Spool magnet 136 detects the position of the spool 130 through detection by a magnetometer (not shown in FIG. 2C). The O-ring seal 138 is attached to the spool shaft 133 to aid in tracking the movement of the spool. The seal around the engine 10 prevents dust and moisture from entering the engine. It functions as follows.

[0038] In this example, the main drive component of the racing engine 10 is a worm drive. The gear unit 140, the worm gear 150, the gear motor 145, and the gear box 144 are The worm gear 150 controls the reverse rotation of the worm drive 140 and the gear motor 145. It is designed to prevent the lacing cable from driving the spool 13 The main input force coming in through 0 is the relatively large worm gear and worm This arrangement means that the teeth of the drive are distributed over the entire teeth of the footwear. Dynamic loads from active use of the platform or tightening the lacing system The gear must be strong enough to withstand both the clamping load from the The gear box 144 is protected from damage by the worm drive 140. This helps protect the more fragile parts of the drive, such as the worm drive key 142. In this example, the worm drive key 142 is connected to a gear box 144. The worm drive 140 interfaces with the pin through a drive shaft coming out of the This arrangement is because the worm drive 140 is axially allowing them to move freely in both directions (away from the gear box 144) By transmitting the axial load to the bushing 141 and the housing structure 100, Thus, the worm drive 140 is connected to the gear box 144 or the gear motor 145. This prevents the application of axial forces.

[0039] FIG. 2D is an illustration showing additional internal components of racing engine 10. In this example, the racing engine 10 includes a worm drive 140, a bushing 141, a gear Gear box 144, gear motor 145, motor encoder 146, motor circuit board 147, and driving components such as worm gear 150.

As shown in this example, the race 131 is aligned with the race groove 11. 0 and runs continuously into the race groove portion 132 of the spool 130. The diagram shows that when the lace 131 is wound by the rotation of the spool 130, the lace 13 The race 131 shows the race recess 135 where the race 1 will be wrapped around. As the raceway travels across the engine 10, it is captured by the raceway groove 132, which As the spool 130 is turned, the race 131 slides against the spool 130 in the race recess 135. It can be rotated onto the main body of the 0.

[0042] As illustrated by the cross section of the racing engine 10, the spool 130 is The spool shaft 133 passes through an O-ring 138 and then In this example, the spool shaft 133 is connected to the spool gear 150 via a connecting pin 134. In some examples, the connecting pin 134 is connected to the spool. The worm gear 150 extends in only one axial direction from the shaft 133. When reversed, most of the worm gear 150 rotates before the contact pin 134 is contacted. The worm gear is contacted by a key on top to allow complete rotation. In addition, a clutch system is implemented to couple the spool 130 to the worm gear 150. In such an example, the clutch mechanism may be configured to The connecting pin 134 can be actuated to allow the spool 130 to rotate freely. In the example where the spool extends in only one axial direction from the spool shaft 133, the spool While the wheel gear 150 is driven in reverse, it is free to move during the initial actuation of the relaxation process. During the initial part of the relaxation process, the spool 130 is allowed to move freely. Allowing this to happen helps prevent tangling of the lace 131. Here's why: It provides time for the user to begin loosening the footwear, which then , which applies tension in a direction that loosens the race 131 before being driven by the worm gear 150. This is because it would mean

[0075] FIG. 10A illustrates a configuration of a powered racing system 1000 according to an example embodiment. FIG. 1 shows a block diagram of the components of a system 1000. The interface may include some, but not necessarily all, of the components, such as interface button 100. 1 (e.g., corresponding to button 121 in the example of FIG. 2A), a foot presence sensor 1010, and 1, a printed circuit board assembly (PCA) having a processor circuit 1020, a battery 1 021, a charging coil 1022, an encoder 1025, a motion sensor 1024, and a drive and a housing structure 100 enclosing a drive mechanism 1040. The drive mechanism 1014 includes, inter alia: , a motor 1041, a transmission 1042, and a race spool 1043. The motion sensor 1024 may be, among others, a single or multiple axis accelerometer, a magnetometer, , gyrometer, or the movement of the housing structure 150 or the housing structure 15 0 or one or more components coupled thereto. In one example, the system 1000 may include a processor. The sensor circuit 1020 includes a magnetometer 1220 connected to the sensor circuit 1020.

[0076] In the example of FIG. 10A, the processor circuit 1020 includes an interface button 1001, A foot presence sensor 1010, a battery 1021, a charging coil 1022, and a driving mechanism 1040 The transmission 1042 communicates data or power signals with one or more of the , a motor 1041 is coupled to a spool 1043 to form a drive mechanism 1040. In the example of A, the button 1001, the foot presence sensor 1010, and the environmental sensor 1050 are It is shown external, or partially external, to the housing structure 150 .

[0077] In an alternative embodiment, the button 1001, the foot presence sensor 1010, and the environmental sensor One or more of 1050 may be encased within a housing structure 150. In one example, the foot presence sensor 1010 is preferably disposed within the housing structure 150. The housing structure 15 is placed in the housing 15 to protect the sensor from sweat, dust, and debris. Minimizing or eliminating connections through the 0 wall increases the durability and reliability of the assembly. It can be useful.

[0078] In one example, the processor circuit 1020 may be configured to For example, the processor circuit 1020 controls the button 1001, the foot presence sensor 101, 0 and motion sensor 1024, 10, the footwear may be adjusted to tighten or loosen the footwear around the foot by, for example, driving a drive mechanism 1040 in response to the In one example, the processor circuit 1020 can be configured to additionally or alternatively, to obtain, among other functions, information from the foot presence sensor 1010 or other sensors. The device is configured to issue instructions to obtain or record sensor information. The processor circuit 1020 (1) detects the presence of a foot using the foot presence sensor 1010; and (2) detecting a predetermined gesture using the motion sensor 1024. , conditions the operation of the drive mechanism 1040.

[0079] In one example, the system 1000 includes an environmental sensor 1050. The information from the sensor 1010 is used to update or adjust the baseline or reference value for the foot presence sensor 1010. As will be further explained below, the measured foot presence by the capacitive foot presence sensor can be used to The capacitance value can change over time, for example, in response to the ambient conditions near the sensor. Thus, information from the environmental sensor 1050 is used to control the processor circuit 1020 and At least one of the foot presence sensors 1010 updates or Can be adjusted.

[0080] In one example, the system 1000 is configured to collect different types of data. In one example, the sensor detects the number, sequence, and pressure of the insole 1201. Collect data regarding the frequency and / or duration of the treatment (e.g., see the description of Figures 12A-12G). For example, the system 1000 may detect the stepping, jumping, and other movements of the wearer while wearing the footwear. The number or frequency of pumps, cuts, kicks, or other compressive forces, as well as ground contact time and air time Other parameters such as time and temperature can be recorded. In another example, the system 1000 may collect this information from footwear. The sequence of compression forces can be recorded, which can include, for example, foot pronation or supination, weight transfer, landing putt In another embodiment, the sensor can be used to identify a footwear, The compressive forces of different parts of the magnets can be quantitatively measured (for example, the magnet groups 1250 to 1250 described later). 52), the measured information may include quantitative compression force and / or impact information. The relative differences in forces at different parts of the footwear can be determined, for example, by the distribution of the wearer's weight, or by the "pressure The weight distribution and / or center of pressure can be used to determine the "center of force" used by the wearer. It can be calculated separately for one or both products of footwear used or, for example, This can be calculated for both the left and right shoes to find the center of pressure or center of weight distribution of the person's whole body. In some instances, the sensors measure compression force (see, e.g., Figures 12E and 12F), ground contact time, Airtime, or time between impacts (e.g. when jumping or running), and / or The rate of change of other time-dependent parameters can be measured. Use or require a certain threshold of force or impact before a force / impact is registered as an event. It is understood that this is possible.

[0081] FIG. 10B illustrates a method 1100 that includes using foot presence information from a footwear sensor. 11 shows a flow chart illustrating an example of a method for detecting a foot presence from a foot presence sensor 1010. The foot presence information includes receiving foot presence information from the footwear. The foot presence information includes receiving foot presence information from the footwear. It may contain binary information about the likelihood that the foot is in the footwear article or may contain a representation of the likelihood that the foot is in the footwear article. The information provided from the foot presence sensor 1010 to the processor circuit 1050 may include an indication of In one example, the foot presence information can include an electrical signal provided by the footwear. The sensor information includes qualitative information about the position of the foot relative to one or more sensors in the sensor.

[0082] At operation 1120, this example determines whether the foot is fully contained within the footwear. If the sensor signal indicates that the foot is fully retracted, this example includes action 1. At 130, this can be followed by actuating the drive mechanism 1040. At 1120, the foot is detected as fully seated, for example based on information from the foot presence sensor 1010. Once determined, the drive mechanism 1040 is engaged to drive the shoe via the spool 1031 as previously described. The laces can be tightened. If the sensor signal indicates that the foot is not fully seated, In this case, in operation 1122, this example performs a predetermined interval (e.g., 1-2 seconds or more). ) after the predetermined delay has elapsed. Then, the example may return to operation 1110, where the processor circuit 1050 detects foot presence sensor 1 The information from 010 is sampled again to again determine whether the foot is fully enclosed. It is possible.

[0083] After the drive mechanism 1040 is actuated in operation 1130, the processor circuit 1050 140 may be configured to monitor foot position information. The path extends from the foot presence sensor 1010 to the absolute or relative position of the foot in the footwear. The information may be configured to be monitored periodically or intermittently. 11. The method of claim 11, further comprising: monitoring foot position information in act 1140; and receiving foot presence information in act 1110. Receiving information may include receiving information from the same or different foot presence sensors 1010. For example, in operations 1110 and 1140, foot presence or position information can be monitored. Different electrodes can be used to achieve this.

[0084] At operation 1140, this example includes one or more buttons, e.g., a button, associated with the footwear. For example, this includes monitoring information from the button 121. The drive mechanism 1040 may be configured to, for example, drive the laces when the user wants to take off the footwear. You can instruct them to slow down or relax.

[0085] In some examples, in addition to or instead of the above, a drive mechanism 1040 may be actuated using a or to monitor lace tension information as feedback information for tensioning the lace. For example, lace tension information can be obtained by measuring the drive current supplied to the motor 1041. Tension can be characterized at the time of manufacture or monitored by the user. can be pre-set or adjusted and correlated to a monitored or measured drive current level. This can be done.

[0086] At operation 1150, this example includes determining whether a foot position has changed within the footwear. The change in foot position is detected by the foot presence sensor 1010 and the processor circuit 1050. If not, the example may continue with a delay at operation 1152. After a certain delay interval, the example may return to operation 1140, where the foot presence sensor 1010 The information is then sampled again to again determine whether the foot position has changed. The delay in can range from a few milliseconds to a few seconds, and is optionally user specified. can.

[0087] In one example, the delay in operation 1152 may be to determine the characteristics of the use of the footwear, for example. The determination may be made automatically by the processor circuit 1050 in response to the For example, the processor circuit 1050 may detect whether the wearer is engaged in strenuous activity (e.g., running, jumping, etc.). If the processor circuit 1050 determines that the device is performing the above-mentioned operation (e.g., the device is performing the above-mentioned operation), the processor circuit 1050 performs the provided The processor circuitry can reduce the duration of the delay that is applied when the wearer is engaged in non-vigorous activity (e.g. If the processor circuit determines that the user is engaged in a certain activity (eg, walking, or sitting), In this case, the duration of the delay provided in operation 1152 can be increased. The sensor sampling events and the processor circuit 1050 and the foot presence sensor 10 10, thereby delaying the corresponding power consumption by at least one of the In one example, when a position change is detected in operation 1150, This example returns to operation 1130, for example, to actuate the drive mechanism 1040 to move the foot This can be followed by tightening or loosening the surrounding footwear. The processor circuit 1050 includes a hysteresis controller for the drive mechanism 1040. or built-in, to prevent unwanted lace rolling up when, for example, a slight change in foot position is detected. Helps to avoid.

[0088] 11A-11D are diagrams illustrating an electric racing engine according to some exemplary embodiments. FIG. 1 is an illustration of a motor control scheme for a motor control system. In one example, the motor control scheme includes: This involves dividing the total travel into segments in terms of lace winding, and the segments The race travel (for example, a "home / loose" position at one end and a The sizes vary based on the location on a continuum between maximum and minimum torque. The radial spool is controlled by a radial encoder on the motor shaft. The segments are primarily controlled in terms of the angle of spool travel. The clock can be sized in terms of the encoder counts. On the "slack" side of the continuum, a segment may have, for example, 10 degrees of spool travel. The reason is that the amount of race movement is not significant. However, as the laces tighten, each part of the lace travel Each increment becomes increasingly important to obtain the desired amount of lace tightness. Other parameters, such as motor current, are secondary to race tightening or continuum position. FIG. 11A shows how different clamping rates can be used as a countermeasure against Includes an illustration of the different segment sizes.

[0089] In FIG. 11A, the entire movement of the race can be divided into a certain number of segments. The amount of travel of the spool can be fixed or variable. For example, the length of a segment is a scale of how the racing engine feels about the intensity of the race. The example in FIG. 11A shows the entire race move 1100 into multiple consecutively arranged segments. For example, one or Multiple segments can be used, for example, on a racing engine or footwear tightness scale. The first, or slack end, can accommodate approximately 10 degrees of rotational spool movement. At the opposite, second, or tensioned end of the scale, the segment rotates about 2 degrees. Other values ​​can be used as well. The rotational position of the pool can be the primary input for the tightness setting, and the motor current can be the secondary It can be used sequentially or as a safety check.

[0090] Figure 11B shows how the current and future positions in the tightness continuum can be calculated using the position in the tightness continuum. This shows how to create a motion profile table based on the desired edge position. The application profile may be generated based on, for example, user input buttons or input signals received from various sensors. The motion profile can be converted into specific inputs such as spool movement information. Parameters, such as acceleration (Accel(deg / s / s)), velocity (Vel(deg / s), deceleration (Dec(deg / s / s)), and movement angle (Angle(deg)) Includes.

[0091] FIG. 11B shows an example of a first table 1101 of spool movement or position characteristics. A profile can be any combination of one or more movement or position characteristics. In some examples, automatic lace tightening events, button presses, and gesture inputs , or other input can initiate or trigger a motion profile. The processor circuit receives this trigger input and then generates the required Updates motor current supply to assist in movement. Provides multiplier or factor for gear reduction. For example, one or more entries in the first table 1101 can be quickly updated or modified. The first table 1101 is only an example and the values ​​shown may be used, for example, by the user. The settings, preferences, or defaults may vary.

[0092] FIG. 11C shows a graph 1103 of an example motion profile. contains an x-axis representing time and a y-axis representing speed. The speed axis corresponds to the speed at which the race or spool is moving. In the example of FIG. 11C, the motion profile "Origin-Comfortable" corresponds to the race can be used to wind and unwind the line, followed by a "relax" motion profile. Ku.

[0093] FIG. 11D generally illustrates a second table 1103, which is arranged along a continuum of footwear tightness. Various user inputs can activate different motion profiles Examples include: In some instances, footwear or racing engines provide baseline comfort. Various factory default settings for fit and performance can be included or used. However, in response to user input such as pressing a button, the racing engine One or more different profiles or movement changes can be implemented. In response to a single press of the "Yes" button, the racing engine has the ability to incrementally move between various segments. In response to the "double" press, the racing engine will You can move between a specific motion profile or a specific In response to a press (e.g., longer than about 250 ms), the racing engine It can be moved between a fully tightened or fully relaxed profile. and the racing engine can be stopped by either user input to the button or other input. can.

[0094] FIG. 12A is a block diagram illustrating footwear components that may include a magnetic foot presence sensor. The example of FIG. 12A is a block diagram of a magnetometer 1220 and a first detector spaced apart from the magnetometer 1220. The magnet 1210 may be generally referred to herein as a "magnet" and may refer to a variety of materials or components. In one example, the first magnet 1210 itself has a magnetic field. Instead, the first magnet 1210 is not sensed by the magnetometer 1220, or The effect on the magnetic field in its vicinity is sensed by magnetometer 1220. References in this specification to a first magnet 1210 (or other magnets or magnetic bodies) may refer to other materials or This may be understood to include the effect of the first magnet 1210 or other material that can be detected by the detector 1220. Cut.

[0095] The magnetometer 1220 is surface mounted or otherwise attached to the main PC assembly 1230. and the PC assembly 1230 can be included within the housing structure 100. In this example, the first magnet 1210 is positioned laterally offset from the longitudinal axis of the magnetometer 1220. For example, the first magnet 1210 can be placed in a foam insole 1201, The insole 1201 is adapted to be fitted to a housing structure 100, for example within an article of footwear. They can be configured to be used or worn adjacently.

[0096] In one example, magnetometer 1220 is manufactured by ST Microelectronics. Electronics' LSM303AGR (e.g., a combination accelerometer and magnetometer) or In some instances, under normal conditions of use, the foot pressure is Therefore, the magnet 1210 is spaced (e.g., within the foam insole 1201) by approximately 0.5-1 mm. In one example, the foam insole 1201 is placed over the housing structure 100. It can be included in the insole or as part of another insole. Other examples may include using a bridge to hold the magnet 1210. , which will be explained further below. The bridge is designed to withstand applied pressure (e.g., from the feet). can serve to increase the force or area over which the magnet 1210 moves. The foam insole 1201 may be, for example, a film on the foam insole 1201 and a magnet. By providing a pressure sensor, the pressure sensor can be selectively coupled to or responsive to an applied pressure. The film can be made to have a variety of hardness, shape, and other properties depending on which area under the foot is to be targeted, for example. The thickness and / or area of ​​the film may vary, i.e., a single or integral film may be used to accommodate different The sensor system may have different regions corresponding to different areas, thereby adjusting the sensitivity of the sensor system. This can be done.

[0097] The magnet 1210 and magnetometer 1220 are arranged such that the magnet 1210 is positioned vertically above the magnetometer 1220. In one example, the magnet 1210 is not necessarily positioned so as to be fixed to the magnet 1210. As shown in the example, the magnetometer 1220 can be offset to one side or the other.

[0098] In the example of FIG. 12A, it is called "foam" but the pressure of the foam insole 1201 The shrink layer may be made of, for example, foam, rubber, silicone, fabric, or polymer-based material or other materials. The compressible layer can be any compressible material. In one example, the compressible layer has a thickness of about 3-10 mm. mm.

[0099] In one example, the racing engine 10 includes a housing structure 100 and a magnetometer. 1220 is included within or on the housing structure 100. In one example, the housing The housing structure is a polycarbonate structure with a wall thickness of about 1 mm. They are made of aluminum, steel, glass, porcelain, rubber, various polymers and plastics. The device may be made of other non-conductive materials, including aluminum.

[0100] FIG. 12A shows an insole 1201 in a first compressed state, with a magnet 1210 and a magnetometer 12 20 are spaced a first distance D1 apart. FIG. 12B shows the insulator in a second, more compressed state. 12, the magnet 1210 and the magnetometer 1220 are separated by a second, shorter distance D2. In one example, the magnetometer 1220 provides distance information to the processor circuit 1020. The processor circuit 1020 may then perform a process for determining the distance or the rate of change between successive distance information. For example, the processor circuitry 1020 may be configured to determine or use distance information. Based on the information, foot impact characteristics such as impact force, or impact timing or frequency may be determined. It can be configured to:

[0101] Although FIGS. 12A and 12B generally show a one magnet, one magnetometer configuration, other configurations are contemplated. For example, multiple magnets can be used with one magnetometer. 1220 and a plurality of magnets 1210 to 1213 (or other magnets detectable by the magnetometer 1220) A footwear component that can include a magnetic foot presence sensor having a discrete material In one example, the plurality of magnets 1210-1213 are The magnets can be located in different places in the product. For example, the magnets can be located in the insole, For example, at different vertical heights above or near magnetometer 1220 and / or magnetometer 1 12C, the first magnet 121 can be placed at different lateral intervals with respect to the second magnet 121. 0 is shifted by a first height and lateral displacement with respect to the magnetometer 1220, and a second magnet 1 211 is a second height and a smaller lateral displacement with respect to the magnetometer 1210 Alternatively or additionally, multiple magnetometers may be used to measure one or more different magnetic fields. It can sense information about stone displacement.

[0102] FIG. 12D illustrates a footwear component including a magnetic foot presence sensor having a magnetometer 1220. In this example, a group of magnets 1250 to 1252 (or magnetometer 1250) are arranged. 220) is aligned along the longitudinal axis of the magnetometer 1220 (i.e., The page is offset laterally (i.e., in the x and y directions) from the z direction (into the page) In this example, information from magnetometer 1220 is used to monitor the presence of feet. The foot position information is monitored to determine the lateral shift in the foot position. For example, the foot on the insole 1201 can be moved forward, backward, For example, the insole 1201 may be connected to the insole 1201. A group of magnets 1250-1252 that can be connected to or placed in the magnetometer 1220 The resulting signal from the magnetometer 1220 indicates the displacement or subsequent movement of the foot. The degree or magnitude of the movement can be indicated.

[0103] In one example, a footwear article (see, for example, FIG. 1) may include a It may include a ferromagnetic material, such as a magnet 1210 or a group of magnets 1250-1252. The product is designed to reduce the strength or otherwise of magnetic fields that are affected by the position of ferromagnetic objects provided or arranged within the product. In one example, the ferromagnetic material and the magnetic field One of the sensors is ferromagnetic, for example, in response to the movement of the feet within the product, or in response to the movement of the product itself. The magnetometer is configured to move relative to one another. When placed in the 1201, the product is used for walking, running, or other activities. When insole 1201 is in place, the ferromagnetic material can move in response to compression or relaxation of insole 1201.

[0104] In one example, the magnetometer 1220 is coupled to the processor circuit 1020. The circuit 1020 can receive a signal from the magnetometer corresponding to the sensed magnetic field strength. In the present invention, the signal contains information about the change or rate of change of the sensed magnetic field. For example, the signal may be , which contains information about the changing location or sequence of locations of the ferromagnetic material relative to the magnetometer 1220. It is possible.

[0105] 12E and 12F show graphs showing time-varying information from the magnetometer. A first magnetic field graph 1261 is shown having a first time-varying magnetic field signal 1271. In one example, In this case, the first time-varying magnetic field signal 1271 can be generated by a magnetometer 1220. , the signal may be, for example, the position of a magnet 1210 relative to a magnetometer 1220 in a first article of footwear. That is, the first time-varying magnetic field signal 1271 is based on the position-related sensing information. It is possible to represent magnetic field strength information over a range of

[0106] In FIG. 12E, a first time varying magnetic field signal 1271 is a baseline or reference magnetic field intensity. The reference magnetic field strength B0 is measured by a footwear that includes a magnetometer 1220 and a magnet 1210. In one example, the reference magnetic field strength B0 corresponds to the reference position of the product. Accommodates or relaxes footwear that is not in use or has not been worn or in an uncompressed state (e.g., when the wearer is sitting or otherwise In some cases, the footwear is designed to be The reference magnetic field strength B0 is, for example, when the wearer is standing substantially motionless and the magnet 1210 is A stationary field such as that biased toward the magnetometer 1220 by a qualitatively constant bias force. Corresponds to the hardware state.

[0107] The example of FIG. 12E shows some of the first time varying magnetic field signal 1271 over the interval shown. In one example, some of the changes are related to the foot strike event or step. The first time T1 may correspond to the start of a first stroke. That is, at a first time T1, the wearer of the product wears a first footwear including the magnet 1210. At a second time T At 2, the first step may have been completed and the wearer's weight is substantially on the first foot. At a second time T2, the The console 1201 may be compressed and the magnet 1210 may move more in relation to the magnetometer 1220. As a result, the magnetometer 1220 is moved to a position closer to the reference position B It is possible to detect a magnetic field strength B greater than that detected at 0.

[0108] The interval from the second time T2 to the third time T3 is when the wearer moves forward through a walking motion and It may represent the release of pressure or compression from the first foot. At least a portion of the embedding event is represented by an interval between the first and third times T1 and T3. At time T3, the magnet 1210 in the first article of footwear , and the magnetometer 1220 again senses the reference magnetic field strength B0. .

[0109] Various information regarding the first stepping event is obtained from the first time varying magnetic field signal 1271. In some instances, the signal magnitude change (e.g., ΔB1 ​​in FIG. 12E) can be determined by a first It is possible to express the foot impact force for a stepping event. The quantitative information can correspond to the displacement of the magnet 1210 relative to the magnetometer 1220. A larger signal magnitude change can correspond to a larger foot impact force, which may be the case for example. When the console 1201 is subjected to a larger foot impact force, it is subjected to a smaller force. It is possible that it may be compressed even further.

[0110] Information about the duration between various magnetic field signal magnitude changes provides information about the foot impact. For example, the duration between the first and second times T1 and T2 can be How quickly the sole 1201, and therefore the foot, transitions from a relaxed state to a compressed state It may indicate how fast the user is moving (walking) in some instances. It may correspond to whether the person is walking, jogging, running, etc. In an example, the duration information may include information regarding the physiological effects of the wearer's own activity or gait. It can be used to assess or provide

[0111] In one example, the type of activity can be determined based on rate of change information from the first time varying magnetic field signal 1271. For example, a magnetic field signal representing a walking gait can be classified based on the The signal is compared to a signal representing a running gait, and the time interval between the peaks and valleys of the signal is A signal representative of a jogging gait can be, for example, a bounce of the signal or a Further differentiation can be made based on other subtle changes in the gait, e.g. The corresponding signal may have longer intervals where the peaks or valleys are rounded. However, the duration between different peak or valley events drifts slowly over time. Signals corresponding to a running gait tend to be more closely spaced and more abrupt. May have distinct peaks or valleys, and may have distinct peak or valley events In between may be included the most constant or static duration over time.

[0112] In the example of FIG. 12E, the first and second times T1 and T2 of the first time varying magnetic field signal 1271 are The rate or slope of change between the second and third times T2 and T3 is different from the rate or slope of change between the second and third times T2 and T3. In this example, the gradient difference is a relatively fast start to the stroke and a relatively slow or This may represent a loose restitution or a transfer to the other foot. The slope of the signal may be relatively constant for different stepping events, and the slope may vary for each step. may be relatively constant for different legs, or for different portions of the magnetic field signal. The rate of change information may be useful, for example, to determine if the wearer tends to "protect" one foot from the other. To analyze the wearer's gait, such as to determine whether the wearer is recovering from an injury, can be used to

[0113] In one example, rate of change information or event information is determined from the time varying magnetic field signal to generate a series of The information can be used to determine foot strike events. In one example, the processor circuit 1020 can be used to calculate distance information. To achieve this, stride length information can be included and used along with foot strike information. In one example, different rate of change information of foot strike for a particular foot strike event may be used. Corresponding different stride length information can be selected by the processor circuit 1020, thereby The accuracy of distance determination is improved.

[0114] FIG. 12F shows a second magnetic field graph 1262 having a second time-varying magnetic field signal 1272. In one example, the second time varying magnetic field signal 1272 can be generated by the magnetometer 1220. , the signal may be, for example, a signal of a magnet 1210 relative to a magnetometer 1220 in a first article of footwear. That is, the second time-varying magnetic field signal 1272 is based on the position-related sensing information. It is possible to represent magnetic field strength information over a range of

[0115] In the example of FIG. 12F, the second time varying magnetic field signal 1272 is a baseline or reference magnetic field. The baseline or reference magnetic field is the same as the baseline used in the example of FIG. The reference magnetic field may be the same as or different from the base line or reference magnetic field. The baseline or reference magnetic field can be different for each user and is input to the magnetometer 1220. may be affected by one or more environmental factors that contribute to the magnetic field strength detected by the As previously explained, the reference magnetic field strength B0 in the example of FIG. 1220 and magnet 1210 may correspond to a reference position on an article of footwear that includes the footwear.

[0116] The example of FIG. 12F shows a second time varying magnetic field signal 1272 over the illustrated time interval. In one example, some of the changes are related to the wearer running. The first time T1 corresponds to a foot strike event or step-on in the running gait. This may correspond to the start of the first stroke. That is, at the first time T1, A wearer of the article applies pressure or force to an insole 1201 of a first article of footwear that includes a magnet 1210. At the second time T2, the first part of the running gait may begin to exert force. The foot may be completed and the wearer's weight may be substantially or completely on the first foot. At a second time T2, the insole may be attached to one of the feet corresponding to the insole. The coil 1201 may be compressed, causing the magnet 1210 to move closer with respect to the magnetometer 1220. As a result, the magnetometer 1220 is detected at the reference position B0. It is possible to detect a magnetic field strength greater than that emitted by the running leg. Tori can represent the wearer moving at a faster speed than walking, The magnetic field strength B detected in the example of FIG. 12F is the magnetic field strength B detected in the example of FIG. 12E. B walking (e.g., the first and second time-varying magnetic field signals 1271 and (Assuming that 1272 corresponds to the same wearer, or a wearer of substantially the same weight.)

[0117] The interval from the second time T2 to the third time T3 is the time during which the wearer is performing the running motion with the first leg. This may represent the first foot moving forward through the first leg and releasing the pressure or compression force from the first leg. During time T3, the magnet 1210 in the first article of footwear is at its baseline or base position. Returning to the home position, magnetometer 1220 again senses the reference magnetic field strength B0.

[0118] Various information regarding the individual steps or strides in the running gait is collected in a second time step. In one example, the signal magnitude change (e.g., FIG. 1) can be determined from the fluctuating magnetic field signal 1272. 2F) may represent the peak foot impact force for the stride length in the figure. As shown in Fig. 1, different stride lengths may have different peak values. A peak or a larger signal magnitude change may correspond to a larger foot impact force. For example, when the insole 1201 is subjected to a larger foot impact force, the insole 1201 is subjected to a smaller force. This is because the material may be compressed even more than if it had been subjected to a shock wave.

[0119] Information about the duration between various magnetic field signal magnitude changes provides information about the foot impact. For example, the duration between the first and second times T1 and T2 can be used to The control 1201, and therefore how quickly the foot goes from a relaxed state to a compressed state. In some instances, this may correspond to how fast the wearer is running. There is a gender.

[0120] FIG. 12G illustrates a method that includes initiating a response of the footwear in use to a magnetic signal. 12 generally illustrates an example of a method 1260. The method 1260 may be implemented, at least in part, by a processor circuit 1262. Method 1 can be performed using information from magnetometer 1220 by operation 1261. 260 includes receiving a signal from the magnetometer 1220. The received signal is 20 includes an analog or digital time-varying signal representative of the time-varying magnetic field detected by the The magnetic field can be, for example, based on the changing position of the magnet 1210 in the footwear. In some instances, the processor circuit 1020 or the particular input conditions may vary. Other dedicated circuitry configured to perform operations based on the magnetometer in operation 1261. It can be configured to receive a signal.

[0121] At operation 1262, the processor circuit 1020 analyzes the received signal and determines whether a magnetic material (e.g., a magnet) 1210) can be used to determine whether, for example, the object has moved or been displaced by more than a certain threshold amount of movement. If no movement is detected, or if a non-large (non-threshold) displacement is detected, method 12 60 can return to operation 1261 to receive further information from the magnetometer 1220. In some examples, a fixed or variable delay may be provided between magnetometer signal sampling events. In act 1262, the magnetic object is determined to have moved more than a certain threshold amount of movement. In this example, in operation 1263, the magnetometer 1220 is included in the footwear in use. It can continue by initiating a response.

[0122] For example, in operation 1263, various footwear functions can be initiated, such as the lace drive mechanism. (operation 1264), determine foot impact characteristics (operation 1265), or The speed is determined (operation 1266). The race drive mechanism is actuated at operation 1264. For example, the race drive mechanism may be operated according to operation 1130 in the example of Example 10B. In one example, actuation 1264 may activate a race drive mechanism. is a foot impulse or a change from a time-varying magnetometer signal (e.g., received in act 1261). Activation of the race drive in act 1264 includes monitoring the rate information based on the sensed foot impact. The method may include automatically adjusting tension of the footwear around the foot in response to the impact information. For example, time variations that indicate strenuous activity such as running or jumping or heavy use. In response to information from the magnetometer signal, actuation 1264 activates a lace drive mechanism to rotate the lace around the foot. The footwear can be tightened within the range. If the information indicates that the wearer is stationary or walking slowly, action 126 At 4 a lace drive mechanism can be activated to loosen the footwear around the foot.

[0123] In one example, actuating the lace drive mechanism in operation 1264 may This involves tensioning the footwear around the foot when it is first put on by the wearer. The magnetometer signals received by the work 1261 indicate when the wearer is about to start moving or stepping into the shoe. In response to this, the drive mechanism can be actuated. The tension level can be adjusted quickly to the first tension level. For example, after the step information is received for the first two step events, the process This can be automatically adjusted by the sensor circuit 1020.

[0124] At act 1265, the example of FIG. 12G determines foot impact characteristics based on the received magnetometer signal. As previously described in the examples of Figures 12E and 12F, the foot impact characteristics include the footwear (and thereby the The foot impact characteristics can include the rate of change of compressive force during, for example, running, walking, etc. Regarding ground time, air time, or time between impacts during jumping or other activities This may include information such as

[0125] In one example, information about foot impact characteristics may be provided to a wearer to inform the wearer that the wearer's feet (individually ) used to provide information about how hard an object lands or strikes a receptive surface The information about foot impact characteristics can be obtained when the wearer is moving with the correct or desired foot placement. Such foot placement information may further include information regarding whether the multi-axis magnetometer In one example, the foot impact characteristic can be confirmed by using the magnets 1250-1252. Sexual information is recorded over time and measured on one or more components of the footwear. For example, the processor circuit 1020 may be Information about foot impact characteristics over time can be used to determine when the insole 1201 needs replacing. You can identify what has happened.

[0126] In act 1266, the example of FIG. 12G uses the received magnetometer signal to determine the stepping speed. As previously described in the examples of Figures 12E and 12F, the stepping speed is measured by a magnetometer. 1220. For example, a magnetic field change showing an increase in magnetic field strength and then a decrease over a specific duration can be , a step event, or the possibility that a step event has occurred.

[0127] FIG. 12G illustrates several methods for determining changes in the magnetic field signal sensed by magnetometer 1220. The available responses are shown, for example, by circuits or devices in the footwear or or other data taken by other devices or processes in data communication with the footwear. Other responses may be initiated as well, including responsive actions. For example, In response, one or more sensors in the footwear, such as a motion sensor 1024 Or data can be collected from an environmental sensor 1050. In one example, the time-varying magnetic field signal The profile or shape can be analyzed by the processor circuitry 1020 to generate gesture information. is identified and one or more other footwear functions, processes, or data transmission events This can be used to trigger events.

[0128] FIG. 13 shows a typical example of a footwear product when the user of the product is standing, i.e. 1 shows generally pressure distribution data for an average foot (left) and a cavus pedis (right). The relatively large plantar pressure areas are the heel region 1301, the ball of the foot region 1302 (e.g., the arch of the foot), and the 1303 (e.g., the “big toe” area), and a thumb area 1304 (e.g., the area between the toe and the toe). However, as previously mentioned, in the central region, for example in or near the arch area, It may be advantageous to include various operational components, including, for example, a foot presence sensor. For example, in this region, the housing structure 100 generally includes The footwear product should be less noticeable or invasive to the wearer. It is possible.

[0129] In one example, a magnetometer, such as magnetometer 1220 in the example of FIGS. 12A-12D, is housed in a housing. The support structure 100 may be included in or on the footwear article and may be located in the arch area of ​​the article. One or more magnets disposed within the insole 1201 may be used to generate magnetic force as described above. This may be located adjacent to the footrest 1220, for example in the arch area of ​​the product. However, the arch area is generally not subject to large changes in pressure or force (e.g., See FIG. 13), and optionally use a bridge component to direct forces from other foot regions to the magnet. and / or to the magnetometer 1220, e.g., depending on the displacement of the magnet relative to the magnetometer 1220. It can resonate or make it more susceptible to displacement.

[0130] 14A and 14B show a bridge component or pressure plate for use with a magnetic sensor. FIG. 14A shows a diagram of a first magnet 1410 mounted on a bridge component 1410. 401. The bridge component 1410 is connected to the lid 142 of the housing structure 100. 0 can be connected to the spring wire 1430. The spring wire 1430 can be, for example, For example, when the first magnet 1401 is not receiving pressure from the foot, or when the footwear including the sensor is When no pressure is applied to the product, the bridge element 1410 is pushed or biased to This can be configured to move the first magnet 1401 to the first position. The spring wire 1430 can act as a cantilever, which can be attached to the lid 1420. 1402 and holds the first magnet 1401 at or near the edge of the cantilever. When force or foot pressure is applied to the bridge component 1410, the bridge component 1410 Regarding the housing structure 100 and the magnetometer 1220 contained in the housing structure 100 In one example, the housing structure 100 and / or Or other components of the footwear, such as the midsole 60, may be configured to, for example, absorb force or foot pressure. When engaged, the bridge component 1410 and the first magnet 1401 are provided with a travel path. A recess configured to receive at least a portion of the bridge component 1410 to provide The cavity may include a portion, a cavity, or a compressible component.

[0131] The bridge components 1410 can have a variety of shapes, contours, or orientations. For example, the bridge component 1410 may be aligned parallel to or parallel to the heel-to-toe axis of the article of footwear. The elongated shape may be oriented vertically. In one example, the elongated shape may be oriented vertically. 13. Receive foot displacement information from the heel region 1301 and / or the big toe region 1303 (see FIG. 13). In some instances, the elongated shape can be configured to accommodate displacement of the left and / or right side of the foot. By receiving information, foot displacement information is received from the arch region.

[0132] In some instances, the bridge component 1410 may be a replaceable element in an article of footwear. The bridge component 1410 may be configured to accommodate a variety of user preferences or physical characteristics. A number of different types or styles of bridge components can be selected for different purposes. Users with high arches may need to wear shoes that are wider or longer than those used by users with low or shallow arches. A bridge component may be used.

[0133] In one example, the footwear article may include a bridge component 1410 and a magnet 1210, etc. The magnetometer 1220 includes at least one ferromagnetic material and is coupled to the bridge component 1410. The bridge components are positioned such that the magnet 1210 and magnetometer 1220 are in a relaxed or reference position. At a certain time, at least one of the magnet 1210 and the magnetometer 1220 is The force meter 1220 may be configured to bias one side of the force meter 1220 away from the other side.

[0134] In some instances, the bridge component 1410 may be rigid or semi-rigid, e.g., flexible. The bridge component is made of a non-woven polymer or a thin metal or ceramic. A magnet is provided in response to a foot displacement force received from the arch area or other area of ​​the foot. 1210 and magnetometer 1220 (e.g., mounted on or in the bridge component 1410). The actuator may be configured to displace one of the actuators (connected thereto) accordingly with respect to its reference position.

[0135] 15(A)-15(C) show a magnet-type foot presence sensor configuration in which the magnetic poles are oriented along the x-axis. Figures 16(A) to 16(C) show test data related to the magnetic poles oriented along the y-axis. 17(A)-17(C) show test data relating to the magnetic foot presence sensor configuration used. 1 shows test data relating to a magnet-based foot presence sensor configuration where the magnetic force is oriented along the z-axis.

[0136] 18A and 18B show magnetic field strength test data for a rectangular magnet. 18F shows the magnetic field strength test data for the first circular magnet. 19A-19D show the magnetic field strength test data for the first circular magnet.

[0137] 15(A) through 22(D) show various test data relating to the magnet and magnetometer. In the examples (A) through (C), the magnetic field strength is unstable or inconsistent along the Z axis of the magnetometer. In general, if the magnet is moved along the X or Y axis, it may move laterally away from the magnetometer, e.g. The magnetic field strength drops off quickly at about 50 mm along the X and Y directions. typically reaches a maximum and then declines.

[0138] 18A-18F show position measurements for different magnet types and magnetometers with different lateral offsets. The magnetic field strength test data corresponding to the device is shown. Based on the examples of Figures 15(A) to 19D, it is possible to determine the allowable range for each type of magnet at some positions. It can be seen that it is possible to provide a satisfactory signal-to-noise ratio (SNR). A minimum deflection of about 0.5 mm is typically used. In some instances, one or more magnet configurations may be less optimal than others. Place magnets to maximize the signal on some axes and not others. This arrangement allows for multi-duty use of the magnetometer. , an index pulse for spool winding or other functions may be possible.

[0139] A variety of different magnet types and shapes can be used. For example, neodymium magnets can be used. Stones can be rectangular, round, toroidal, small (e.g., 0.1” diameter x 100 mm thick) approximately 1.02 mm (0.04”)), or large (e.g., diameter approximately 6.35 mm (0.25”) ) × thickness of approximately 1.52 mm (0.06”).

[0140] The inventors optimized the performance of the magnetometer for footwear with short magnet travel or deflection distances. To do this, the magnet is moved away from the Z axis associated with the magnetometer, i.e., away from the longitudinal or Z axis of the magnetometer. It has been found that the axial direction should be spaced laterally or sideways from the axis.

[0141] In some instances, footwear articles may include or use capacitive foot presence sensors. The capacitive foot presence sensor may include a surface type sensor or a projection type sensor. Surface type sensors use a thin film of light at the corners that can be distributed across the entire sensor surface. In this example, the surface of the capacitive sensor is, for example, an insole, a tongue, This may include on the walls of the footwear article or on the interior surface of the footwear article elsewhere. Projection sensors can use a grid of conductive elements arranged in rows and columns. In the case of the 100mm type, body parts or feet may be in contact with or in close proximity to the film and / or conductive elements. When placed on the ground, it transfers a charge to the leg to complete a circuit, thereby creating a voltage change. It is possible to do so.

[0142] FIG. 20 generally illustrates an example of a capacitive sensor 1500. The capacitive sensor 1500 includes a plurality of capacitive sensors. The plate may include, for example, a capacitive sensor 150 on the housing structure 100. 0, which is located on or near the sole of the foot when the footwear article is worn. can be arranged so that

[0143] The foot presence sensor 1500 can include multiple capacitive plates. In the example of FIG. The four capacitive plates are identified as 1501 through 1504. The capacitive plates are The foil can be made of a conductive material such as a foil. The foil can be flexible and can be Optionally, it can be embedded in the plastic of the housing structure 100. It is understood that any conductive material may be used, such as rubber, ink, etc.

[0144] The capacitance of a capacitor is a function of the dielectric constant of the material between the two plates that form the capacitor. In the sensor 1500, the capacitor is connected to a capacitor plate 1501. 〜1504。 Therefore, the capacitor plate can be formed between each pair of two or more. There are six effective capacitors formed by the six unique combinations of 1501 to 1504. Optionally, two or more of the plates may be electrically connected to form a single That is, the first and second capacitor plates 15 01 and 1502 can optionally be electrically linked together to serve as half of a capacitor. The third and fourth capacitor plates 1503 and 1504 are now electrically connected. Form the halves.

[0145] The capacitive effect between the first and second capacitor plates 1501 and 1502 is shown in FIG. The capacitor is represented by an imaginary line identified with the letter A. The first and third capacitance plates 1 The capacitive effect between 501 and 1503 is represented by a phantom capacitor identified with the letter B. The capacitive effect between the second and fourth capacitor plates 1502 and 1504 is represented by the letter C. The third and fourth capacitor plates 15 are represented by phantom lines. The capacitive effect between the 1503 and 1504 is represented by a phantom capacitor identified with the letter D. The capacitive effect between the second and third capacitive plates 1502 and 1503 is identified by the letter E. The first and fourth capacitance plates 1501 and 1502 are represented by an imaginary capacitor. The capacitive effect between the MOSFET and the FET is represented by an imaginary capacitor identified with the letter F. If present, each of the imaginary line capacitors extends between a respective pair of capacitor plates. It will be seen that the electrostatic field is represented by the capacitance plate. The capacitor formed by the pair is identified by the imaginary line in FIG. Refer to the product by the same letter (e.g., "A", "B", etc.) used to identify it.

[0146] For each pair of capacitor plates in the example of Figure 20, the effective dielectric constant between the plates is The body includes an air gap (or other material) between the plates. For each pair of capacitor plates, any part of the legs adjacent to the respective pair of capacitor plates This portion also becomes part of the effective dielectric for that capacitor plate pair. The dielectric constant between each pair of supports is related to the proximity of the legs to each pair of plates. For example, the closer the legs are to a pair of plates, the higher the value of the effective permittivity. As the dielectric constant increases, the capacitance increases.

[0147] The foot presence sensor may include a plurality of capacitive sensor drive / monitor circuits. A capacitor circuit can be associated with each pair of capacitor plates in the example of FIG. In one example, the drive / monitor circuit may couple a drive signal (e.g., an electrical excitation signal) to a capacitor. Each drive / The monitor circuit includes an associated capacitor (e.g., capacitor "A" is connected to the first and second plates). The capacitance of the capacitor 1501 corresponds to the capacitance of the capacitor 1502. The drive / monitor circuit can be configured to provide a signal indicative of the measured capacitance value. It may have any suitable structure for making the measurements.

[0148] In one example, the capacitance value measured by the drive / monitor circuitry is The controller can be operated in a processor circuit (see, for example, the processor circuit of FIG. 10A). The actuation includes providing a race mechanism actuator. can be implemented by "hardwired" components and by a processor running software It can be implemented by a combination of hardwired components and software. In the above, the function of operating the race mechanism is (1) monitoring the signal from the drive / monitor circuit. (2) detecting a particular threshold value (processor circuit and / or processor circuit and If any of them show a capacitance value exceeding the capacitance stored in the memory circuit that communicates data, (3) identifying which of the feet are located in close proximity to the sensor matrix; Characterizing the location, size, etc., based on, for example, the number of thresholds that are exceeded; and ) depending on its characterization, including permitting, altering, or inhibiting the operation of the race drive mechanism. .

[0149] FIG. 21 generally illustrates an example capacitive electrode configuration 1600. This example is for application to a substantially flat surface. The first and second electrodes 1601 and 1602 are arranged, for example, in a comb shape along the The sensor circuit (see FIG. 8A) controls the stimulation applied to the first and second electrodes 1601 and 1602. The device can be configured to generate a stimulation signal and sense a response signal indicative of a change in capacitance between the electrodes. may be affected by the presence of the body or feet relative to the electrodes. Two electrodes 1601 and 1602 are disposed on or near the surface of the housing structure 100. , for example, adjacent to the foot.

[0150] In one example, the foot presence sensor includes an etched conductive layer, which may be, for example, an electrode. The pattern may be an XY grid or multiple separate parallel layers of conductive material, e.g. For example, by etching to form a grid with vertical lines or tracks. In this and other capacitive sensors, no direct contact between the body or foot and the conductive layer is required. The conductive layer may optionally be embedded in the housing structure 100, or can be coated with a protective or insulating layer.

[0151] In one example, the capacitive foot sensor stores information about the mutual capacitance between multiple electrodes or plates. The mutual capacitance sensor is configured to sense or use the information in each row and in each electrode grid. A capacitor may be included at each intersection of the rows. Optionally, the electrode grid includes In one example, electrode signals can be applied to the rows or columns, and the sensors Body or legs close to the surface may change the local electric field, which in turn reduces the mutual capacitance. It is possible to measure the capacitance change at each individual point on the grid and, for example, to measure the voltage on each axis. By measuring the mutual capacitance, the position of the body can be determined. In one example, the mutual capacitance measurement method is Information from multiple locations around the grid can be provided simultaneously.

[0152] In one example, the mutual capacitance measurement uses an orthogonal grid of transmit and receive electrodes. In a capacitive sensor system, each detection can be detected as a separate XY coordinate pair. In an example, information from multiple measurements of a capacitive sensor can be used to determine the presence of a foot. In some instances, rate of change information regarding the X and / or Y detection coordinates can be used.

[0153] In one example, a self-capacitance based foot presence sensor is used in the same XY grid as the mutual capacitance sensor. In a self-capacitance sensor, the columns and rows can be operated independently. The volume loading of the body in each column or row can be detected independently.

[0154] In one example, the capacitive sensor optionally includes electrodes or electrodes having a relatively large surface area. The sensor may have a plate and be capable of sensing changes in capacitance over a correspondingly large area. Cut.

[0155] In one example, a capacitor-based foot presence sensor has a baseline or reference capacitance value. The baseline capacitance value can be determined by measuring the surface area of ​​the electrodes or other footwear components. The effect of the sensor on the sensor response may be a function of the electrode placement, or of the orientation or environment of the sensor or footwear itself. That is, the sensor can detect any relevant volume even when the foot is not in the footwear. The sensor may have a quantity value, which may be determined by measuring one or more materials or environments at or near the sensor. The effect of the dielectric constant of the material in the footwear may be a function of the dielectric effect of the environmental factors. An insert (e.g., an insole) can change the dielectric properties of the capacitive sensor. However, the processor circuitry may optionally detect changes in the baseline or reference characteristic. The capacitive sensor is configured to calibrate or self-calibrate when the insole is replaced, for example. can.

[0156] The inventors have conducted various tests to determine the effect of various prosthetic inserts on capacitive foot sensing. The effects of full-length and partial-length orthotic insoles were tested. Adding (partial-length) orthotics to footwear increases the overall dielectric effect, The signal amplitude was also reduced with the presence of the prosthesis. The RMS amplitudes were similar with and without the brace. Responses under loaded or unloaded conditions were also The results were about the same.

[0157] Detects the presence of a foot with a regular or full-length orthosis based on orthosis test results Using capacitive sensing to measure the signal is feasible in terms of signal to noise resolution. When using a full-length brace, the presence of the foot was clearly distinguished under both low and high load conditions. The SNR measured exceeded the minimum required for the automatic calibration of the sensor, which is approximately 6 dB. The positive has enough offset range to compensate for the additional dielectric effect of the appliance.

[0158] For full-length orthotics, the test procedure involves removing the production insole and placing the orthotic itself. The dielectrics were nearly equivalent, and as a result, the SNR in compression was significantly higher than that in the brace. The results were similar to those without the treatment.

[0159] The air gap between the full-length orthosis and the sensing electrodes reduces the SNR depending on the applied load. Measurable changes occurred. The various foot regions behaved similarly under low load conditions and under the brace. No permanent deformation of the gap distance was observed, such as that caused by standing up. Under high load conditions, the arch of the brace compresses against the sensor enough to eliminate the gap. The resulting electric field can be as large as the production insole. In some instances, this change may be equivalent to using a full-length brace (without a brace). This can be compensated for by using a gap-filling foam behind the

[0160] FIG. 22A generally illustrates an example of a capacitive foot presence sensor. The electrode may include a capacitive sensing electrode 1721 coupled to a controller circuit 1722. 1721 and / or the controller circuit 1722 may optionally be mounted in the housing structure 1 It can be included in or attached to 00.

[0161] In one example, the controller circuit 1722 may be an Atmel ATSAM L21E18B-MU, ST Microelectronics STM32L476M from NVIDIA Corporation, or other similar devices. As shown, the electrode 1721 is optionally recessed in the top of the housing structure. 1201, or may be included as part of the foam insole 1201 or elsewhere. do.

[0162] In the example of FIG. 22A, the electric field may emanate from the top surface of electrode 1721. In the example, the electric field below the electrode is reduced by placing a driven shield under the sensing electrode. The driven shield and the sensing electrode 1721 are electrically isolated from each other (see FIG. 22B). If the sensing electrodes 1721 are on one surface of the PCB or FPC, the drive The shield may be either the bottom layer of a PCB or an inner layer underneath a multi-layer PCB or FPC. In one example, the driven shield can be placed on top of the sensing electrode 1721. 1721. The surface area of ​​the sensing electrode 1721 may be smaller or larger than the surface area of ​​the sensing electrode 1721. The shield can be of the same polarity, phase, and / or impedance as the x-axis leg of the sensing electrode 1721. The electric field of the shield can be driven to produce an electric field of amplitude 1721. repelling and thereby preventing undesirable coupling effects with, for example, the lower ground plane of the main PCA. This can be insulated.

[0163] One advantage of using capacitive sensing to detect foot presence is that the capacitive sensor is placed in the arch area. Capacitive sensors can function well even when the user has high arches. For example, a preferred implementation of the foot presence sensor is to protect it from sweat and dust, for example. The inside of the housing structure 100 may be included to allow for connection through the housing. Minimizing or eliminating connections increases reliability. A preferred location for placing the cushion is in the arch area, which is felt by the wearer and is least likely to cause the discomfort.

[0164] In one example, the sensing electrode 1721 detects signals between multiple electrodes, for example between X and Y electrodes. In one example, a suitable sampling period is about 2 to 5 The capacitive sensing method can also be used with insoles or socks around the foot. The effect of such moisture on the detection is relatively invariant to sweat (moisture) inside the sensor. This may be due to a reduction in the dynamic range, which means that the presence of moisture reduces the measured volume. However, in some instances, the dynamic range can be increased by It is sufficient to accommodate this effect within the expected moisture levels.

[0165] FIG. 22C generally illustrates a top view (left) and a perspective view (right) of the sensing electrode 1725. The sensing electrodes are disposed inside the housing structure 100, for example, on the top of the housing structure 100. At or near (e.g., pressed against or adjacent to) the inner side wall In one example, the sensing electrodes 172 5 includes a flexible substrate.

[0166] In order to confirm the effectiveness of foot presence detection using the capacitive sensing method, the inventors have In one example, capacitive sensing for foot presence detection was performed with a signal-to-noise resolution of It is possible to measure an SNR of 22 dB with a 99.9% probability. Sixteen subjects were used in the study, of which four were female and 12 were male. The distribution of self-reported schizophrenia was normal, ranging from 5.5 to 12.5. Arch height showed a normal distribution. The R value was 0.039, which was consistent with the signal quality and subject foot size. There was no correlation between the

[0167] In one example, the foot presence sensor includes a first pressure sensor. in the toe sole 60, in the side or upper components of the footwear, or in the The first pressure sensor may be embedded in the device or in other locations. The device can be configured to sense a change in mass when weight is applied to the device. The pressure sensor may include a pressure sensitive resistor.

[0168] FIG. 23A is a block diagram illustrating a footwear component that may include a pressure-based foot presence sensor. 23A shows an example of a pressure sensor cover 2100. The SACAB 2100 is a substantially air-tight or liquid-tight case in which a measuring membrane is placed. The measurement membrane can move or react to changes in the distribution of gas or fluid within the case 2100. As shown, the pressure sensor cover 2100 is positioned under the foot. The footwear can be configured to receive physical foot impacts when the footwear is worn. In one example, the pressure sensor case 2100 shares a wall with the housing structure 100. or adjacent to the wall. In response to a foot impact, at least one of the cases 2100 The walls of the case can move slightly, thereby changing the gas or fluid distribution inside the case. Information from the sensor or membrane regarding changes in fluid distribution is transmitted to a processor circuit (e.g., FIG. 10). A processor circuit 1020) to identify foot presence or foot activity information. can be used for

[0169] FIG. 23B illustrates the racing engine 10 of FIG. 2B having a second pressure sensor 1820. The second pressure sensor 1820 is connected to the housing of the racing engine 10. The racing engine 10 can be embedded inside the engine structure 100. It can be vapor sealed or hermetically sealed. The housing 10 may be a substantially closed structure, including at least an airtight portion. A second pressure sensor 1820 may be embedded within the hermetic chamber 1810. The hermetic chamber 1810 can be contained inside the housing structure 100. The hermetic chamber 1810 is in contact with or adjacent to the housing structure 100. The wall may include one or more walls shared by

[0170] In one example, the second pressure sensor 1820 is embedded in the hermetic chamber 1810. For example, when a user places their weight on an article of footwear while standing or walking, When subjected to forces, one or more surfaces of the hermetic chamber 1810 may deflect. , and can bend, thereby changing the gas distribution inside the hermetic chamber 1810. The membrane of the second pressure sensor 1820 moves in response to such changes to the gas distribution. The sensor signal from the second pressure sensor 1820 can be generated to indicate the movement of the membrane. A signal can therefore indicate the presence of a foot when membrane movement is detected.

[0171] In some examples, information from a foot presence sensor or magnetometer can be used as a pedometer. For example, changes in the time-varying magnetic field signal from magnetometer 1220 may occur when the footwear article is in motion. Optionally, the information from the magnetometer can be combined with other sensor information to show that Together, these may be used or processed, for example together with accelerometer or temperature information, to determine if a step event has occurred. This can be useful for identifying the processor circuit (e.g., the processor circuit of FIG. 10A). 1020) receives the magnetometer signal and responsively measures the number of steps taken by the wearer. Besides its use as a pedometer, it can be used to determine information about This information can be used to determine speed or movement.

[0172] In some instances, the magnetometer can be configured to monitor a physiological characteristic of the wearer. For example, the sensor may store information about the expansion or contraction characteristics of the foot, as detected from pressure changes in the foot itself. The present invention can provide pulsation characteristics, or other physiological information, such as blood pressure, blood flow, and blood pressure.

[0173] In some instances, a magnetometer can provide information about displacement or force. When the footwear includes the information, the information on the foot strike can be obtained. For example, foot strike information may include information about the force or impact of the wearer's foot. Whether you are standing (low impact, low force), running (medium impact, medium force), or can be used to determine if you are jumping (high impact, high force).
