Abstract
Description
[0001] This application claims priority over the preliminary US patent application 63 / 703,562 filed on October 4, 2024, which is hereby fully incorporated by reference. SPECIALIZATION
[0002] The present disclosure relates to bicycle components and in particular to position detection devices for bicycles. BACKGROUND
[0003] Bicycles are known to be equipped with moving components. These include brakes, suspension, adjustable seatposts, and the like. Measuring these components can provide useful feedback on their operation. Brake components can move into various positions corresponding to lever travel, brake pad position, braking force, and more. Suspension components can move into various positions corresponding to stem position, wheel travel, and more. Accurate positional monitoring of bicycle components is desirable for obtaining feedback for tuning and control.
[0004] Therefore, there is a need for bicycle components that facilitate position detection in different operating modes. GENERAL DESCRIPTION
[0005] One objective of the present disclosure is to describe various position sensing devices for bicycles. Position sensing devices can be used to provide data to riders and tuners. For example, position sensing devices can be provided to determine the position of a brake component during operation and to generate position information about the operation of the brakes. Such brake position information can be used for brake tuning, for controlling other components such as the suspension, and / or for controlling a drive motor, as in an electrically assisted bicycle or e-bike. Position data can be generated at sufficiently short time intervals to determine useful speed data of position changes. For example, a height-adjustable seat post can be measured to determine whether an extension speed indicates a need for maintenance.Detailed positional data can be used to map the positions, speeds, accelerations, and more of various components. For example, suspension components can be mapped in terms of average position, minimum position, maximum position, minimum speed, maximum speed, minimum acceleration, maximum acceleration, and various other aspects. The accurate and rapid positional tracking of bicycle components described herein serves as a basis for guidance and confirmation of bicycle setup and can further be used to provide useful riding data to the rider and even a larger group chosen by the rider.
[0006] According to one aspect, a position detection device for a bicycle is provided, wherein the position detection device comprises: a bicycle component defining an interior and an exterior space; a detectable element arranged in the interior of the bicycle component, wherein the detectable element is movable relative to the bicycle component; and at least one detection element arranged in the exterior space of the bicycle component, wherein the at least one detection element is operable to detect: a first position of the detectable element relative to the bicycle component and a second position of the detectable element relative to the bicycle component, wherein the second position differs from the first position.
[0007] According to another aspect, a position detection device for a bicycle is provided, wherein the position detection device comprises: a bicycle component defining an interior and an exterior space; a field-generating element arranged in the interior of the bicycle component and generating a field that can be detected in the exterior space of the bicycle component; and at least one detection element arranged in the exterior space of the bicycle component and operable in such a way as to detect the field generated by the field-generating element.
[0008] According to another aspect, a position detection device for a bicycle is provided, wherein the position detection device comprises: a first component; a detectable element arranged on the first component; a second component which is movable along an axis relative to the first component over a travel range; a first detection element arranged on the second component, wherein the first detection element is operable to detect the detectable element in a first section of the travel range; and a second detection element arranged on the second component, wherein the second detection element is operable to detect the detectable element in a second section of the travel range which differs from the first section of the travel range.
[0009] According to another aspect, a suspension component for a bicycle is provided, wherein the suspension component comprises: a first tube defining a first tube volume; a second tube that is at least partially arranged in the first tube volume, the second tube defining a second tube volume; a detectable element that is fixed relative to the second tube and is at least partially arranged in the first tube volume; and at least one detecting element that is arranged outside the first tube volume and the second tube volume.
[0010] According to another aspect, a method for detecting the positions of a bicycle component is provided, wherein the method comprises: moving a detectable element along a travel path between a first position and a second position; generating a first output based on a movement of the detectable element from the first position to the second position with a first detection element; generating a second output different from the first output based on a movement of the detectable element from the first position to the second position with a second detection element; and determining position data based on the first output and the second output with a processor.

[0013] The following section describes in detail the present embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. In the detailed description, numbers and letters are used for designation to refer to features in the drawings. Identical or similar designations in the drawings and in the description have been used to refer to identical or similar parts of the invention.
[0014] The term "exemplary" here means "serving as an example, case, or illustration." Any implementation described herein as "exemplary" is not necessarily to be understood as preferred or advantageous over other implementations.
[0015] The terms “first,” “second,” “third,” etc., used herein may be used interchangeably to distinguish one component from another and do not indicate the location or significance of the individual components. Unless otherwise specified or evident from the context of use, these terms have no significance for priority or chronological sequence but serve merely to identify multiple elements or components for the convenience of understanding the disclosed examples. According to some embodiments, the term “first” may be used to refer to an element in the detailed description, while a different term such as “second” or “third” may be used for the same element in a claim. In such cases, these terms are used simply for the sake of simplicity to refer to multiple elements or components.
[0016] Unless otherwise specified herein, the terms "coupled", "attached", "attached to" and similar terms refer to direct coupling, fastening or attaching as well as indirect coupling, fastening or attaching via one or more intermediate components or features.
[0017] The singular forms “ein / eine” and “der / die / das” include the plural forms, unless otherwise clearly evident from the context.
[0018] An approximate formulation, as used herein in the description and claims, is employed to modify any quantitative representation that may permissibly vary without altering the fundamental function to which it relates. Accordingly, a value modified by one or more terms such as "about," "approximately," and "essentially" is not limited to the precisely stated value. In at least some cases, the approximate formulation may correspond to the accuracy of an instrument for measuring the value or the accuracy of the methods or machinery for designing or manufacturing the components and / or systems. For example, the approximate formulation may refer to a tolerance of 1, 2, 4, 10, 15, or 20 percent.
[0019] In this document and throughout the entire description and claims, domain boundaries are combined and exchanged; such domains are identified and encompass all subdomains contained therein, unless the context or language indicates otherwise. For example, all domains disclosed herein include the endpoints, and the endpoints are independently combinable with one another.
[0020] Various suspension components can be provided with reference to the following disclosure. For example, front suspension forks, rear suspension shock absorbers, seatposts, and various other suspension components are considered in conjunction with the features described below. Taking the front suspension of a bicycle as an example, a front fork typically comprises a crown, a steerer tube extending upward from the crown, and two legs extending downward from the crown. Each leg comprises an upper tube connected to the crown and a lower tube connectable to the front wheel. The upper and lower tubes are arranged in a telescopic relationship. In some cases, a damper is arranged in one of the legs and a spring (e.g., an air spring, a coil spring) is arranged in the other leg.The spring allows the front fork to compress when riding over bumps or obstacles, thus reducing the transmission of shocks and vibrations to the rider. When no further pressure is applied, the fork returns to its extended position. With an air spring, pressure in a suspension component can be potentially dangerous if it is suddenly released.
[0021] Suspension components on a bicycle can employ a position sensing device. The position sensing devices described herein can be operated to measure the travel position of various suspension components. Such travel measurements can be performed once, for example, to support the setup before riding; periodically, for example, to confirm measurements during a ride; or continuously, for example, to track and report ride data such as suspension velocity and acceleration. It is desirable that the position sensing occurs without affecting the suspension function. For example, position sensing devices can be advantageously designed to wirelessly detect the positions of suspension components.
[0022] This document discloses exemplary suspension components with position sensing devices. According to various embodiments, the position sensing devices described herein can be operated to measure the travel of various suspension components. Position sensing devices can be wireless and communicate, for example, via one or more elements of a suspension component. In general, position sensing devices can acquire, store, and transmit suspension position data as described in this document.
[0023] Regarding the characters: Fig. Figure 1 shows an example of a human-powered vehicle in which the exemplary front forks disclosed herein can be used. In this example, the vehicle is a possible type of bicycle 100, such as a mountain bike. In the illustrated example, the bicycle 100 comprises a frame 102, a front wheel 104, and a rear wheel 106, which are rotatably coupled to the frame 102. In the illustrated embodiment, the front wheel 104 is coupled to the front end of the frame 102 via a front fork 108. A forward-facing direction of travel or orientation of the bicycle 100 is indicated by the direction of arrow A in Figure 1. Fig. 1 is displayed. A forward direction of movement for bicycle 100 is therefore indicated by the direction of arrow A.
[0024] In the illustrated embodiment of Fig. Figure 1 of the bicycle 100 comprises a saddle 110, which is coupled to the frame 102 (e.g., near the rear end of the frame 102 relative to the forward direction A) via a seat post 112. The bicycle 100 also comprises handlebars 114, which are coupled to the front fork 108 (e.g., near a front end of the frame 102 relative to the forward direction A) so that the bicycle 100 can be steered. The bicycle 100 is shown on a riding surface 116. The riding surface 116 can be any riding surface, e.g., the ground (e.g., a dirt path, a sidewalk, a road, etc.), an artificial structure above the ground (e.g., a wooden ramp), and / or any other surface.
[0025] In the illustrated embodiment, the bicycle 100 has a drive train 118 comprising a crank assembly 120. The crank assembly 120 is functionally coupled via a chain 122 to a chainring assembly 124 attached to a hub 126 of the rear wheel 106. The crank assembly 120 comprises at least one, typically two, crank arms 128 and pedals 130, as well as at least one front chainring or chainring 132. A rear gear-shifting device 134, e.g., a derailleur, is arranged on the rear wheel 106 to move the chain 122 to different chainrings of the chainring assembly 124. Additionally or alternatively, the bicycle 100 can have a front gear-shifting device (not shown) to move the chain 122 through the gears on the chainring 132.
[0026] The exemplary bicycle 100 comprises a suspension system with one or more suspension components. The front fork 108 is or comprises a shock absorber with a spring and a damper, as disclosed in detail herein. In the illustrated embodiment, the bicycle 100 further comprises a rear suspension component 136, which is a shock absorber referred to herein as the rear shock absorber 136. The rear shock absorber 136 is coupled between two sections of the frame 102, including a rear triangle, also referred to herein as the swingarm 138, which is coupled to the rear wheel 106. The front fork 108 and the rear shock absorber 136 absorb shocks and vibrations during riding the bicycle 100 (e.g., when riding on rough terrain). According to further embodiments, the front fork 108 and / or the rear shock absorber 136 can be integrated into the bicycle 100 in other configurations or arrangements.
[0027] According to Fig. In the illustrated exemplary bicycle 100, at least one position detection device can be used. In the illustrated embodiment, a front position detection device 140 and a rear position detection device 142 are implemented. The front position detection device 140 is attached together with the front fork 108. At least one section of the front position detection device 140 can be integrated into the front fork 108. For example, the front position detection device 140 can have an inner section (not shown) that is arranged inside the front fork 108. The front position detection device 140 can also include an outer section (not shown) that is arranged outside the front fork 108.The front position sensing device 140 can comprise one or more elements arranged in a front position sensing housing (not shown) that is mounted on or integrated into the front fork 108. As described in more detail below, the front position sensing device 140 serves to detect the position of the front fork 108.
[0028] The in Fig. The rear position sensing device 142 shown in Figure 1 is attached together with the rear suspension component 136. Although the rear position sensing device 142 is in Fig. Although the rear position sensing device 142 is designed to directly measure the position of the rear suspension component 136, it should be noted that the rear position sensing device 142 could also be used to detect the position of another component, e.g., the swing arm 138. The rear position sensing device 142 can have one or more elements integrated into the rear suspension component 136. For example, the rear position sensing device 142 can have an inner section (not shown) located inside the rear suspension component 136. The rear position sensing device 142 can also have an outer section (not shown) located on or integrated into the rear suspension component 136.For example, the rear position sensing device 142 may have one or more elements arranged in a rear position sensing housing (not shown) which is attached to or integrated into the rear suspension component 136.
[0029] As previously described, the front position sensing device 140 and / or the rear position sensing device 142 can be operated to detect the positions of their respective suspension components. The front position sensing device 140 and the rear position sensing device 142 can acquire, store, and transmit data indicating the position of these components. Position sensing can be performed during a suspension setup phase before or during a drive. The position information generated by the front position sensing device 140 and / or the rear position sensing device 142 can be reported to provide information about suspension travel, sag, bottoming out, and more.For example, the collected position data can be used to determine an average, median, or weighted average value of the suspension position over a sampling period, which may be part of an entire trip or an entire trip.
[0030] Data collected by the front position sensing device 140 and / or the rear position sensing device 142 can be used for various downstream purposes related to suspension performance. For example, position data can be used to display service recommendations based on a total suspension cycle distance or a number of cycles. Furthermore, characterizations of the ride and / or the driver can be provided based on the collected position data. For example, highly variable position data may indicate a harsh or aggressive ride, while very limited position data may indicate a smooth or consistent ride.
[0031] Position data can be compared between multiple position sensing devices. For example, data from the front position sensing device 140 can be compared with data from the rear position sensing device 142 to provide position compensation data. Such position compensation data can be used to indicate suspension compensation, for example, relative to an average or recommended suspension compensation. Suspension compensation data can be used to provide a characterization of the driver, for example, by indicating a more aggressive driving style, where the front position sensing device 140 detects a large travel range compared to the small travel range detected by the rear position sensing device 142.
[0032] Position data can be reported in real time to one or more other components of the bicycle and / or to another device, such as a mobile device. Position data can be analyzed in real time and / or reported in a post-ride report. Real-time data can be used for operations such as adjusting the suspension or other components. For example, position data can be analyzed, which in turn can lead to adjustments to the shock control, suspension settings, spring rate, gear shifter, dropper post, or various other adjustable characteristics of bicycle components. Position data from the post-ride report can be used to track performance over multiple rides and / or characterize ride data.For example, location data, combined with GPS data and known locations such as trails, can be used to provide information about those trails. In various implementations, location data matched to a specific trail could be used to characterize trails in terms of their roughness or difficulty and to suggest similar trails that a rider might enjoy or want to avoid. It's worth noting that a rider's location data can be compiled to create a database of their own suspension performance, or that this data can be aggregated with the location data of other riders to compare suspension performance and / or generate average data that provides insight into the trails and can then be shared with other riders to assist with route planning.
[0033] Further driver characterizations can be generated by processing the position data collected by the front position sensing device 140 and / or the rear position sensing device 142. For example, an objective "score" can be provided to a driver after the drive, displaying various driving characteristics such as total time in the air, maximum suspension travel, average ride height, number of times the suspension travel exceeded a certain position threshold, and much more. The post-drive "score" can serve to indicate the overall technical level of the drive and provide the driver with a benchmark for their performance, as well as, if desired, enabling social competition on various online platforms.
[0034] Although in Fig. Figure 1 shows a suspension arrangement. According to further embodiments, the suspension system can use only one suspension component (e.g., only the front fork 108) or more than two suspension components (e.g., an additional suspension component on the seat post 112) in addition to or as an alternative to the front fork 108 and the rear shock absorber 136. Generally described, suspension components herein can comprise a first suspension element and a second suspension element movable relative to the first suspension element. A pressure chamber or other spring is provided to preload the first suspension element away from the second suspension element, for example, along a suspension axis. The first suspension element or the second suspension element is connected or connectable to an unsprung section (i.e., an unsprung section) of the bicycle 100, while the other is connected to a sprung section of the bicycle 100 (i.e.,is connected or connectable to a section supported by the suspension.
[0035] Although the in Fig. Although the exemplary bicycle shown in Figure 100 is a mountain bike, the exemplary front forks (and / or lower housings or casings) disclosed herein can also be used on other types of bicycles. For example, the disclosed front forks can be used on racing bicycles as well as bicycles with mechanical (e.g., cable, hydraulic, pneumatic, etc.) and non-mechanical (e.g., wired, wireless) drive systems. The disclosed front forks can also be used on other types of human-powered two-, three-, and four-wheeled vehicles. Furthermore, the exemplary front forks can be used on other types of vehicles, e.g., motor vehicles (e.g., motorcycles, cars, trucks, etc.).
[0036] Fig. Figure 2 is a schematic representation of a position detection device 200. The position detection device 200 of Fig. 2 can generally be used as a front position sensing device 140 and / or a rear position sensing device 142 of Fig. 1 or as another position detection device described elsewhere herein. In general, the position detection device 200 comprises at least one detectable element 216 that can be detected by at least one first detection element 220 and one second detection element 222. The first detection element 220 and the second detection element 222 can be used to determine location data with the detectable element 216. For example, the first detection element 220 and the second detection element 222 can be used to determine a position, for example a telescopic position, of a bicycle component by detecting the detectable element 216.
[0037] As in Fig. As shown in Figure 2, a first telescopic component 202 is provided. Furthermore, a second telescopic component 204 is provided and is movable along an axis T. According to various embodiments, the first telescopic component 202 and the second telescopic component can be referred to as telescopic suspension components, telescopic brake components, or with other suitable modifiers. The second telescopic component 204 is movable along the axis T relative to the first telescopic component 202. The first telescopic component 202 and the second telescopic component 204 can each be configured as different components, including brake components or suspension components. As described herein, reference is made to suspension components; however, it should be noted that similar features and arrangements could be used with reference to brake components, for example, as described in Figure 2. Fig. 14 described below.
[0038] According to Fig. 2 An internal volume 206 can be defined between the first telescopic component 202 and the second telescopic component 204. The illustrated internal volume 206 is sealed against an external environment 208 by a sealing element 210. The sealing element 210 is in Fig. Figure 2 is shown schematically, but could be any dynamic sealing arrangement that allows relative movement between the first telescopic component 202 and the second telescopic component 204 while maintaining a seal. For example, the sealing element 210 can comprise one or more O-rings, square seals, labyrinth seals, or lip seals. The sealing element 210 can also have or interact with a lubricating feature (not shown), for example, a foam element that retains a lubricant.
[0039] The embodiment of Fig. Figure 2 further shows various alignment features. A first alignment feature 212 is provided near the sealing element 210. A second alignment feature 214 is provided at a distance from the first alignment feature. The first alignment feature 212 and the second alignment feature 214 can be spaced apart from each other along the axis T according to the alignment requirements, for example, to counteract relative movement between the first telescopic component 202 and the second telescopic component 204 resulting from a force component perpendicular to the axis T. The first alignment feature 212 and the second alignment feature 214 can be designed with bearing surfaces that facilitate telescopic movement between the first telescopic component 202 and the second telescopic component 204.According to one embodiment, the first alignment feature 212 and the second alignment feature 214 are designed as bushings that are fixed to the first telescopic component 202 and are displaceable relative to the second telescopic component 204. One or more lubricant retention features (not shown) can be provided in the first alignment feature 212 and / or the second alignment feature 214.
[0040] According to Fig. In the second telescopic component 204, a detectable element 216 is arranged within the internal volume 206. As shown, the detectable element 216 is fixed relative to the second telescopic component 204 in a housing 218 of the detectable element. The housing 218 of the detectable element can be designed as a recess in the second telescopic component 204 or be a separate element that holds the detectable element 216 in position relative to the second telescopic component 204. According to various embodiments, a holder 219 for the detectable element can be provided to hold the housing 218 of the detectable element relative to the second telescopic component 204. The detectable element 216 is arranged such that it moves with the second telescopic component 204 along the axis T and can be used to indicate the position of the second telescopic component 204.The detectable element 216 can be a magnet, for example an electromagnet or a permanent magnet. According to further embodiments, the detectable element 216 can be a powered signal transmitter, for example a radio device.
[0041] As previously described, the detectable element 216 can be a permanent magnet. For example, an embodiment of the detectable element 216 with a single permanent magnet can generate a single magnetic field. As described in more detail below, a single permanent magnet, or alternatively a permanent magnet with a non-repeating magnetic field, can be used to consistently determine a position of the first telescopic component 202 relative to the second telescopic component 204. For example, one or more detection elements, as described in more detail below, can be configured to provide a variable output based on a relative position of the detectable element 216.
[0042] The detectable element 216 in Fig. Section 2 defines a field F in which it is detectable. It is noted that the field F is determined partly by the detectable element 216 and partly by relevant detectors or detection elements, as described in more detail below. The field F can represent a magnetic field, for example, in an embodiment of the detectable element 216 with a single permanent magnet. The field F can be adjustable, for example, between at least two axes. In the illustrated embodiment, the field F has a first field axis F1 and a second field axis F2, which is orthogonal to the first field axis F1. According to one embodiment, the first field axis F1 and the second field axis F2 are each representative of a field strength and can describe magnetic field lines, for example, magnetic field lines with a strength suitable for detection. As shown, the first field axis F1 has a greater strength than the second field axis F2.The detectable element 216 can be configured to adjust a magnetic field to achieve a desired strength of the first field axis F1 and the second field axis F2. For example, several permanent magnets, ferromagnetic and / or non-magnetic elements can be arranged to shape the magnetic field of the permanent magnet embodiment of the detectable element 216. It should be noted that other embodiments of the detectable element 216 could achieve a desired ratio between the first field axis F1 and the second field axis F2. For example, an embodiment of the detectable element 216 with a radio device can be oriented such that it has a greater extent in the first field axis F1 than in the second field axis F2. Furthermore, according to some embodiments, the second field axis F2 can have a greater strength than the first field axis F1.According to such an embodiment, the greater strength is aligned in the axial direction relative to the axis T.
[0043] As already described, the detectable element 216 is fixed in position relative to the second telescopic component 204, and the second telescopic component 204 is movable within the first telescopic component 202. When the second telescopic component 204 moves along the axis T within the first telescopic component 202, one or more detectors can be operated to detect the detectable element 216, for example, by detecting the field F. According to the embodiment of Fig. Figure 2 provides a first detection element 220 with a first telescopic component 202. The first detection element 220 is capable of wirelessly detecting the position of the detectable element 216. For example, the first detection element 220 can be a magnetometer, a Hall-effect sensor, or another sensor configured to generate an output corresponding to the field strength F of the detectable element 216. As the detectable element 216 moves relative to the first detection element 220, the corresponding output of the first detection element 220 changes in a predictable manner that can be continuously measured. The first detection element 220 can thus generate an output indicating the field strength F and the relative position of the detectable element 216 and the first detection element 220.Since the first sensing element 220 is fixed in position relative to the first telescopic component 202 and the sensable element 216 is fixed relative to the second telescopic component 204, the output of the first sensing element 220 can be used to wirelessly display the relative position of the first telescopic component 202 and the second telescopic component 204. According to some embodiments, such a relative position can be referred to as a travel path, for example, in a range between the minimum and maximum travel paths.
[0044] According to Fig. 2. The first detection element 220 and all subsequent detection elements can be operated in such a way that they detect the detectable element 216 across one or more other components. For example, the first detection element 220 can be configured to detect the detectable element across the second telescopic component 204. The first detection element 220 is adjustable such that an output generated by the movement of the detectable element 216 on a side opposite the second telescopic component 204 or any other component arranged between them represents a relative position of the detectable element 216 and the first detection element 220.
[0045] The first detection element 220 described above can be operated to detect the detectable element 216 over a range of relative positions. This range of relative positions of the detectable element 216 and the first detection element 220 can be described with reference to a field range R. As used herein, the field range R is measured as the detectable area of the field F on a detection plane P. The detection plane P, as used herein, represents a position of the first detection element 220 parallel to the axis T along which the first telescopic component 202 and the second telescopic component 204 move relative to each other. The first detection element 220 defines a first detection axis P1 extending from the detection plane P. The first detection axis P1 is, as shown, orthogonal to the detection plane P and to the axis T.It should be noted, however, that the first sensing element 220 can be operated to perform sensing along different axes. According to one embodiment, the first sensing element 220 can be operated to perform sensing along the first sensing axis P1 and along an orthogonal first sensing axis that runs parallel to and is represented by the sensing plane P. According to such an embodiment, the first sensing element 220 can generate an output based on a combination of sensing along the first sensing axis P1 and along the sensing plane P or the orthogonal first sensing axis, for example, as an angle-indicating vector. As the sensing element 216 moves along the axis T relative to the first sensing element 220, the resolution along the first sensing axis P1 or the sensing plane P may decrease (i.e., the resolution may decrease).A change in the detected strength may be small relative to a change in the travel path of the detectable element 216 along the axis T. According to this embodiment, the output, based on a combination of detections along the first detection axis P1 and along the detection plane P, can ensure that an output is generated which indicates an accurate travel position of the detectable element 216 along the axis T. Although described herein as generally orthogonal and parallel to the travel axis T, it should be noted that detections along each axis may be at a relative angle to the travel axis T or to other detections.
[0046] The first detection element 220 can be used, as already described, for the wireless detection of the positions of the detectable element 216. For example, the one in Fig. The first detection element 220, as shown in Figure 2, is capable of detecting positions of the detectable element 216 that correspond to an overlap of the field range FR relative to the first detection axis P1. Although the first detection element 220 can still generate outputs in response to positions of the detectable element 216 outside this overlap of the field range FR, the resolution may be reduced. It should be noted that the strength and shape of the field F and the detection performance of the first detection element 220 are adjustable features and can be adapted to achieve desired ranges and resolutions. However, as described below, additional detection elements may also be provided.
[0047] According to Fig. 2. The first detection element 220 can be adjustable such that it detects the detectable element 216. For example, according to some embodiments, the detectable element 216 can provide a peak magnetic field strength of ±5, 10, 15, or 20 millitesla (mT). Accordingly, the first detection element 220 and each additional detection element can be set with a sensitivity range of ±5 mT, ±25 mT, or ±50 mT.
[0048] Fig. Figure 3 is a schematic view of the position detection device 200. Fig. 2 in a second position. The one in Fig. Figure 3 shows a spring movement of the first telescopic component 202 relative to the second telescopic component 204 from the position shown in Fig. The first position is shown in Figure 2. When the second telescopic component 204 moves along the travel axis T in a compression direction C, the detectable element 216 moves in a similar manner relative to the first detecting element 220. As shown in Figure 2. Fig. As shown in Figure 3, the field range FR of the detectable element 216 overlaps the first detection axis P1 of the first detection element 220, but the field range FR of the detectable element 216 also overlaps a second detection axis of a second detection element 222. The second detection element 222 is spaced apart from the first detection element 220. As shown, the second detection element 222 is spaced apart from the first detection element 220 by a first distance D1 along the detection plane P. According to the present embodiment, the first distance D1 is set such that it provides a larger area than a single detection element and at the same time ensures that at least one detection element is always operational to generate an output, based on sensor data, that indicates a position of the detectable element 216. According to one embodiment, the first distance D1 is smaller than the field range FR.According to such an embodiment, an effective traverse measurement range could be represented by the first distance D1 plus twice the field range FR, since the detectable element 216 can be detected by at least the first detection element 220 or the second detection element 222 in this entire range.
[0049] It should be noted that the field range FR is an adjustable feature to achieve various objectives. For example, the field range FR can be adjusted by increasing the field strength, e.g., by providing a stronger permanent magnet. The field range FR can also be adjusted by setting the field strength, for example, by arranging permanent magnets to strengthen the first field axis F1 and decrease the second field axis F2. The field range FR can also be adjusted by setting the detection power of one or more detection elements, such as the first detection element 220. According to one embodiment, the field range FR is set such that the detectable element 216 can be detected by both the first detection element 220 and the second detection element 222 in at least one travel position.As above, the first distance D1 can be set according to the field range FR, for example, less than or equal to the field range FR. According to various embodiments, the first distance D1 is at least twenty millimeters (20 mm), thirty millimeters (30 mm), forty millimeters (40 mm), fifty millimeters (50 mm), sixty millimeters (60 mm), seventy millimeters (70 mm), or eighty millimeters (80 mm).
[0050] According to the illustrated embodiment, the first detection element 220 can be configured to detect a position or a range of positions of the detectable element 216, and the second detection element 222 can be configured to detect a position or a range of positions of the detectable element 216. As shown in Fig. As shown in Figure 2, the first detection element 220 can be set to detect this first position of the detectable element 216 shown in Figure 2. The second detection element 222 can be set to detect the position shown in Figure 2. Fig. The second position of the detectable element 216, as shown in Figure 3, is detected. As already described, the first detection element 220 can have a range of detection accuracy. For example, the first detection element 220 can have a continuous range of detection accuracy defined by its overlap with the field range FR. According to another embodiment, the first detection element 220 can have a non-continuous range, defined, for example, by its overlap with the field range FR, but excluding a central area where the first field axis F1 overlaps the first detection element 220. According to this embodiment, outputs of the first detection element can be supplemented or replaced by another detection element, such as the second detection element 222. As in Fig. As shown in Figure 3, the first detection element 220 and the second detection element 222 can have identical or similar overlaps with the field range FR at some positions of the detectable element 216. According to this embodiment, comparisons with expected values can be used to decide which output should be used for position determination. For example, a first lookup table can be used to compare expected output values of the first detection element 220, and a second lookup table can be used to compare expected output values of the second detection element 222. It should be noted that, based on these comparisons, data from either the first detection element 220 or the second detection element 222, or both, can be used for position determination of the detectable element 216.
[0051] According to Fig. 3. The depicted position of the second telescopic component 204 relative to the first telescopic component 202 can also be referred to as an intermediate position. As in Fig. As shown in Figure 3, the detectable element 216 is positioned between the first detection element 220 and the second detection element 222 along axis T and along the detection plane P. In this intermediate position, the detectable element 216 can be detected by both the first detection element 220 and the second detection element 222. For example, the first detection element 220 and the second detection element 222 can be configured to detect this intermediate position of the detectable element 216.
[0052] Fig. Figure 4 is a schematic view of the position detection device 200. Fig. 2 and Fig. 3 in a third position. As in Fig. As shown in Figure 4, the field range FR overlaps with a third detection axis P3 of a third detection element 224. As in Fig. As shown in Figure 4, the third detection element 224 is spaced from the second detection element 222 by a second distance D2 along the detection plane P. According to the present embodiment, the second distance D2 is set such that it provides a larger range than a combination of only the first detection element 220 and the second detection element 222, while simultaneously ensuring that at least one detection element is always operational to generate an output, based on sensor data, indicating the position of the detectable element 216. According to one embodiment, the first distance D2 is smaller than the field range FR. As shown, the second distance D2 can be similar to or equal to the first distance D1, as already described.According to such an embodiment, an effective traverse measurement range could be represented by the first distance D1 plus the second distance D2 plus twice the field range FR, since the detectable element 216 can be detected by at least the first detection element 220, the second detection element 222 or the third detection element 224 in this entire range.
[0053] According to Fig. Section 4 defines a third distance D3 between the first detection axis P1 of the first detection element 220 and the third detection axis P3 of the third detection element 224. The third distance D3 can be used to define an overall detection range. For example, the overall detection range can be defined as the third distance D3 plus twice the field range FR, since the detectable element 216 can be detected by at least the first detection element 216, the second detection element 222, or the third detection element 224 within this entire range. As described above, the third distance D3 includes the first distance D1 and the second distance D2. According to one embodiment, the third distance D3 can be twice the size of the first distance D1 or twice the size of the second distance D2.However, the third distance D3 can be greater than twice the first distance D1 or greater than twice the second distance D1, for example if the first distance D1 and the second distance D2 are not equal.
[0054] As in third position in Fig. As shown in Figure 4, one or more features can be provided to control the movement of the second telescopic component 204 relative to the first telescopic component 202. For example, a first travel stop 234 and a second travel stop 236 can be provided on the first telescopic component 202 and on the second telescopic component 204, respectively. According to the Fig. In the embodiment shown in Figure 4, the first traverse stop 234 is configured to form a physical interface with the second traverse stop 236. The first traverse stop 234 can be configured as a spring, for example as an elastomeric element, so that a stop area is controlled. The second traverse stop 236 can be a surface or other feature provided on the second telescopic component 204 and can be elastomeric or substantially incompressible. According to one embodiment, an elastomeric embodiment of the first traverse stop 234 provides increasing resistance to the movement of the second telescopic component 204 as the second telescopic component 204 moves in the compression direction C.Accordingly, an interaction between the first travel stop 234 and the second travel stop 236 can serve to dampen a pressure or impact force between the first telescopic component 202 and the second telescopic component 204, for example in a spring-loaded embodiment of the schematic embodiment of . Fig. 2-4.
[0055] As already mentioned with reference to Fig. As described in section 3, the first distance D1 can be at least 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, or 80 mm. It should be noted that various other dimensions for the first distance D1 are possible. For example, a brake design can be shown in the schematic representation of Fig. 2-4 have a first distance in the range of two millimeters (2 mm) to ten millimeters (10 mm). In a spring design of the schematic representation of Fig. In 2-4, the second distance can be at least 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, or 80 mm. According to this embodiment, the third distance D3 can therefore be at least twice these values. Based on the areas described above, including twice the field range FR, the total detectable areas can be described. According to an embodiment that includes only the first detection element 220, an area twice the size of the field range FR can be detected. The size of this area of the first detection element 220 can be at least forty millimeters (40 mm), sixty millimeters (60 mm), eighty millimeters (80 mm), one hundred millimeters (100 mm), one hundred twenty millimeters (120 mm), one hundred forty millimeters (140 mm), or one hundred sixty millimeters (160 mm). By including further detection elements, the detection area can be increased.For example, this area can be enlarged by the size of the first distance D1 by including the second detection element 222 in the first detection element 220. By including the third detection element 224 in the first detection element 220 and the second detection element 222, the size of this area can be increased by the size of the second distance D2.
[0056] According to Fig. Figure 4 shows a communication interface 232, which communicates with the first detection element 220. The communication interface 232 can be operated to transmit a signal in response to a detection by the first detection element 220. According to the illustrated embodiment, the communication interface 232 communicates with the first detection element 220, the second detection element 222, and the third detection element 224. The communication interface 232 and the first detection element 220 or further detection elements can be in direct communication or have one or more features in the communication between them. For example, as shown in Fig. As shown in Figure 4, the first detection element 220, the second detection element 222, and the third detection element 224 each communicate with a processor 228. The processor 228 is configured to process outputs from the detection elements 220, 222, and 224. According to this embodiment, the processor 228 is further configured to transmit an output to the communication interface 232. The output of the processor 228 can represent various outputs from the detection elements 220, 222, and 224. For example, the processor 228 can generate an output indicating the position of the detectable element 216 based on an output from at least one of the detection elements 220, 222, and 224.
[0057] The processor 228 can also transmit outputs to the detection elements 220, 222, 224. For example, the processor 228 can transmit an output to at least one of the detection elements 220, 222, 224 to adjust detection quality and / or performance. According to one embodiment, the processor 228 transmits an output to at least one of the detection elements 220, 222, 224 to increase detection performance based on a detected noise level or a marked output from the at least one of the detection elements 220, 222, 224.
[0058] The processor 228 can be configured in various ways for communication between at least one of the sensing elements 220, 222, 224 and the communication interface 232. According to some embodiments, the communication interface 232 can be integrated into the processor 228, for example, on the same circuit board. For instance, the processor 228 can be a system-on-a-chip (SoC) processor. The processor 228 and the communication interface 232 can thus be configured to process outputs from at least one of the sensing elements 220, 222, 224 and to transmit an output to another device, such as a portable device, main unit, or other bicycle component. According to various embodiments, the processor 228 can be a processor from the Nordic Semiconductor® nRF family. For example, the processor 228 can be a Nordic Semiconductor® nRF52833, nRF52840, or nRF54L15.
[0059] The communication interface 232 can be wired or wireless. As previously described, the communication interface 232 can be wired to the processor 228 or otherwise integrated into the processor 228. The communication interface 232 can also be wired to at least one of the sensing elements 220, 222, or 224. The communication interface 232 can additionally or alternatively include a radio link. For example, the communication interface 232 can include at least one of the following radio links: Bluetooth®, Mesh, Thread, LoRa, NFC, ANT, 802.15.4, 2.4 GHz, or Zigbee, for sending and / or receiving signals. It should be noted that the communication interface 232 and / or the processor 228 can be configured to transmit encrypted signals and can use a counter or a rolling code to further secure communication.
[0060] According to Fig. Figure 4 shows a power source 226 that communicates with at least one of the sensing elements 220, 222, 224. As shown, the power source 226 communicates with and supplies power to the processor 228, the communication interface 232, the first sensing element 220, the second sensing element 222, and the third sensing element 224. The power source 226 can be replaceable and / or rechargeable. According to one embodiment, the power source 226 is at least one coin cell battery. For example, the power source 226 can be a coin cell battery of type CR1620, CR1632, CR2032, CR1025, or CR2477. The power source 226 can be removable, for example, without tools. As shown in Fig. As shown in Figure 4, the power source 226 can be housed in one or more structures. For example, the illustrated embodiment provides a sensing housing 230 in which the power source 226 is housed. The sensing housing 230 of the present embodiment contains the processor 228, the communication interface 232, the first sensing element 220, the second sensing element 222, and the third sensing element 224.
[0061] As previously described, one or more electrical components can be arranged inside the detection housing 230. For example, the power source 226 can be removable or non-removable within the detection housing 230. The power source 226 can also be located outside the detection housing 230. For example, the power source 226 can be removable and attached to an outer surface of the detection housing 230.
[0062] Fig. 5 is a diagram showing the outputs of the Fig. The position detection device 200 shown in 2-4 is illustrated. The diagram in Fig. Figure 5 shows various lines measured along an x-axis 580 and a y-axis 590. The x-axis 580 represents a travel position of the second telescopic component 204 relative to the first telescopic component 202. For example, the x-axis 580 could be a linear scale specified in millimeters. The y-axis 590 represents the detector output, for example, the outputs of the first sensing element 220 and the second sensing element 222, as described above. Fig. 2-4 described. The y-axis can therefore represent a magnetometer value, which is given, for example, in mT.
[0063] In the diagram in Fig. Lines 5 and 5 are represented as a first line 510, a second line 520, a third line 530, and a fourth line 540. The first line 510 and the second line 520 represent a first output of a first capture element and a second output of the first capture element, respectively. This is in reference to... Fig. The first data capture element described in section 5 can be any data capture element and is described using the example of the first data capture element 220, which was described above with reference to Fig. 2-4 as described. As shown in the diagram in Fig. As shown in Figure 5, the first line 510 describes a maximum output 502 of the first line, which can be an absolute maximum output or a local maximum output. According to the embodiment of a magnetometer described above with reference to Fig. As described in 2-4, the maximum output of 502 of the first line is... Fig. 5 represents a maximum magnetometer reading.
[0064] According to Fig. 5 describes the second line 520 as a maximum output 503 of the second line, which can be an absolute maximum output or a local maximum output. In the above in Fig. In the example described in 2-4, the maximum output 503 of the second line represents a maximum magnetometer reading. The maximum output 502 of the first line and the maximum output 503 of the second line can represent different maximum outputs of the same magnetometer. For example, a multi-axis magnetometer can be used, where the first line 510 and the second line 520 represent an output of the first axis of the multi-axis magnetometer and an output of the second axis of the multi-axis magnetometer, respectively. The first axis and the second axis can have any angular relationship, but in this example, they are described as orthogonal, i.e., perpendicular to each other. For example, the first line 510 can represent an axial magnetometer reading (i.e., parallel to the acquisition plane P in ). Fig. 2-4) and the second line 520 a radial magnetometer reading (i.e. perpendicular to the detection plane P, for example along the first detection axis P1 in Fig. 2-4).
[0065] The in Fig. The second line 520 shown in Figure 5 further describes a minimum output 501 of the second line. To continue with the multi-axis magnetometer example described above: The minimum output 501 of the second line represents a local or absolute minimum of the radial magnetometer value of the first sensing element 220, as described with reference to Figure 5. Fig. 2-4 described. Accordingly, the second line 520 describes both a minimum output 501 of the second line and a maximum output 503 of the second line. As can be seen from the diagram in Fig. As can be seen in Figure 5, the second line 520 can be described as a line with a first peak output corresponding to the minimum output 501 of the second line and a second peak output corresponding to the maximum output 503 of the second line, while the first line 510 can be described as a line with a single peak output corresponding to the maximum output 502 of the first line. As described above, in the example of an axial magnetometer reading, the peak outputs of the second line 520 represent magnetometer peak outputs parallel to the acquisition plane P in Figure 5. Fig. 2-4 were measured, while the peak output of the first line 510 in the example of a radial magnetometer represents a peak output of the magnetometer that is measured along the first detection axis P1 in Fig. 2-4 was measured.
[0066] According to Fig. 5. A first peak-to-peak distance D7 is measured between the minimum output 501 of the second line and the maximum output 502 of the first line. A second peak-to-peak distance D8 is measured between the maximum output 502 of the first line and the maximum output 503 of the second line. Together, the combination of the first peak-to-peak distance D7 and the second peak-to-peak distance D8 can be referred to as the first central magnetometer zone. In this combination of the first peak-to-peak distance D7 and the second peak-to-peak distance D8, the axial and radial components of a first magnetometer work together to provide reliable data based on a relatively strong magnetic field measurement. Near each peak, there is a high rate of change along the y-axis 590 for a given path along the x-axis 580. As referred to in Fig. As described in more detail below, the first line 510 and the second line 520 can be combined, for example, to represent an angle in order to achieve a relatively constant rate of change along the y-axis 590 over the entire first peak-to-peak distance D7 and the second peak-to-peak distance D8. Accordingly, the first peak-to-peak distance D7 and the second peak-to-peak distance D8 can represent a range of high-precision magnetometer values from a first magnetometer, for example, the one described above with reference to Fig. 2-4 described first recording element 220.
[0067] According to Fig. 5. The third line 530 and the fourth line 540 together can describe axial and radial magnetometer values, for example as above with reference to the second detection element 222 in Fig. 2-4 described. As shown in the diagram in Fig. As shown in Figure 5, the third line 520 describes a maximum output 505 of the third line, which can be an absolute maximum output or a local maximum output. According to the embodiment of a magnetometer described above with reference to Fig. As described in sections 2-4, the maximum output of 505 of the third line is... Fig. 5 represents a maximum magnetometer value. The fourth line 540 describes a maximum output 506 of the fourth line, which can be an absolute maximum output or a local maximum output. In the above in Fig. In the example described in 2-4, the maximum output 506 of the fourth line represents a maximum magnetometer reading. The maximum output 505 of the third line and the maximum output 506 of the fourth line can represent different maximum outputs of the same magnetometer. For example, a multi-axis magnetometer can be used, where the third line 530 and the fourth line 540 represent an output of the first axis of the multi-axis magnetometer and an output of the second axis of the multi-axis magnetometer, respectively. The first axis and the second axis can have any angular relationship, but in this example, they are described as orthogonal, i.e., perpendicular to each other. For example, the third line 530 can represent an axial magnetometer reading (i.e., parallel to the acquisition plane P in ). Fig. 2-4) and the fourth line 540 a radial magnetometer reading (i.e. perpendicular to the detection plane P, for example along the second detection axis P2 in Fig. 2-4).
[0068] The in Fig. Figure 5, the fourth line 540, further describes a minimum output 504 of the fourth line. To continue with the multi-axis magnetometer example described above: The minimum output 504 of the fourth line represents a local or absolute minimum of the radial magnetometer value of the second sensing element 222, as described with reference to Fig. 2-4 described. Accordingly, the fourth line 540 describes both a minimum output 504 of the fourth line and a maximum output 506 of the fourth line. As can be seen from the diagram in Fig. As can be seen in Figure 5, the fourth line 540 can be described as a line with a first peak output corresponding to the minimum output 504 of the fourth line and a second peak output corresponding to the maximum output 506 of the fourth line, while the third line 530 can be described as a line with a single peak output corresponding to the maximum output 505 of the third line. As described above, in the example of an axial magnetometer reading, the peak outputs of the fourth line 540 represent magnetometer peak outputs parallel to the acquisition plane P in Figure 5. Fig. 2-4 were measured, while the peak output of the third line 530 in the example of a radial magnetometer represents a peak output of the magnetometer that is measured along the second detection axis P2 in Fig. 2-4 was measured.
[0069] According to Fig. A third peak-to-peak distance D9 is measured between the minimum output 504 of the fourth line and the maximum output 505 of the third line. A fourth peak-to-peak distance D10 is measured between the maximum output 505 of the third line and the maximum output 506 of the fourth line. Together, the combination of the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10 can be referred to as the second central magnetometer zone. In this combination of the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10, the axial and radial components of a second magnetometer work together to provide reliable data based on a relatively strong magnetic field measurement. Near each peak, there is a high rate of change along the y-axis 590 for a given path along the x-axis 580. As referred to in Fig. As described in more detail below, the third line 530 and the fourth line 540 can be combined, for example, to represent an angle in order to achieve a relatively constant rate of change along the y-axis 590 across the entire third peak-to-peak distance D9 and the fourth peak-to-peak distance D10. Accordingly, the third peak-to-peak distance D9 and the fourth peak-to-peak distance D10 together can represent a range of high-precision magnetometer readings from a second magnetometer, for example, the one described above with reference to Fig. 2-4 described second recording element 222.
[0070] According to Fig. 5. The first central magnetometer zone, defined by the first tip-to-tip distance D7 and the second tip-to-tip distance D8, can be spaced apart from the second central magnetometer zone, defined by the third tip-to-tip distance D9 and the fourth tip-to-tip distance D10. This space can represent a distance between the first and second magnetometers, for example, in the case of the first detection element 220 and the second detection element 222, as described above with reference to Fig. As described in sections 2-4, a first distance D4 can be defined between the maximum output 502 of the first line and the maximum output 505 of the third line. A second distance D5 can be defined between the maximum output 503 of the second line and the maximum output 506 of the fourth line. A third distance D6 can be defined between the minimum output 501 of the second line and the minimum output 504 of the fourth line. The first distance D4, the second distance D5, and the third distance D6 can be equal, for example, if the first peak-to-peak distance D7, the second peak-to-peak distance D8, the third peak-to-peak distance D9, and the fourth peak-to-peak distance D10 are equal. It should also be noted that these relative distances can be adjusted depending on sensor placement and / or sensitivity.
[0071] Together, the first distance D4, the second distance D5, and the third distance D6 define a magnetometer overlap zone in which, for example, outputs from the first and second magnetometers can be used together. In particular, a zone defined between the maximum output 503 of the second line and the minimum output 504 of the fourth line can be used to define a distance between the nearest peak outputs of the respective magnetometers, which may be spaced apart or overlap as shown. According to one embodiment, this distance between the nearest peak outputs can be set such that the distance between the respective magnetometers is maximized while simultaneously ensuring reliable position data over this entire range.
[0072] According to the in Fig. In the embodiment shown in Figure 5, the total path length along the x-axis 580 between the origin on the y-axis 590 and a maximum path length 509 is represented. Within this range, individual magnetometers may have defined usable ranges. For example, magnetometer data within a region near the peaks may be particularly useful. As shown, the first magnetometer data, represented by the first line 510 and the second line 520, may define a first magnetometer range D11 between the origin on the y-axis 590 and a first magnetometer transition 508. The first magnetometer transition 508 does not necessarily represent a point at which the first magnetometer values are no longer used or preferred, but may instead represent a point from which only the second magnetometer values are used.The second magnetometer data represented by the third line 530 and the fourth line 540 can define a second magnetometer range D12 between a second magnetometer transition 507 and the maximum path 509. The second magnetometer transition 507 does not necessarily represent a point at which the second magnetometer values are no longer used or preferred, but can instead represent a point from which only the first magnetometer values are used. It should be noted that the described ranges are adjustable and can overlap to any extent.
[0073] In Fig. In section 5, an overlap region D13 is defined between the second magnetometer transition 507 and the first magnetometer transition 508. The overlap region D13 specifies a region in which the first and second magnetometers, for example the first detection element 220 and the second detection element 222 of Fig. 2-4, provide useful position data. It should be noted that an embodiment may be configured such that the entire movement takes place within the overlap area D13, or that, as in Fig. Figure 5 shows that useful measurements beyond this overlap area D13 are possible through the individual use of data from the first and second magnetometers.
[0074] Fig. 6 is another diagram showing the outputs of the Fig. The position detection device shown in diagrams 2-4 is illustrated. The description of the diagram is as follows: Fig. 6 continues to be carried out using the above exemplary embodiment of the diagram from Fig. 5. In particular, using the same quantities along the axes shown, the embodiments of Fig. Reference is made to sections 2-4. However, it should be noted that the diagram in Fig. It could represent 6 different values and sizes that are representative of other embodiments considered herein. The diagram in Fig. 6 has an x-axis 680, which represents a travel position of the second telescopic component 204 relative to the first telescopic component 202, and a y-axis 690, which represents a detector output.
[0075] In Fig. Figure 6 shows a fifth line 615 and a sixth line 635. The fifth line 615 and the sixth line 635 represent first and second magnetometer data, respectively. For example, the fifth line 615 can establish a relationship between the first line 510 and the second line 520 of Fig. 5 describe, for example, an angular relationship. Referring to the multi-axis magnetometer example described above, the fifth line 615 represents a calculated angle based on orthogonal components, such as axial and radial components. The sixth line 635 in Fig. 6. According to this embodiment, a relationship can be established between the third line 530 and the fourth line in Fig. 5 describes, for example, an angular relationship. Referring to the multi-axis magnetometer example described above, the sixth line 635 represents a calculated angle based on orthogonal components, such as axial and radial components.
[0076] As from Fig. As can be seen in Figure 6, the fifth line 615 can provide consistent and reliable position data at least between the origin on the y-axis 690 and the first magnetometer transition 508. Between the first magnetometer transition 508 and the maximum path 509, the fifth line 615 can provide relatively unpredictable position data. According to this embodiment, the data from the sixth line 635 provide consistent and reliable position data over this range. The sixth line 635 can provide consistent and reliable data at least between the second magnetometer transition 507 and the maximum path 509. Between the origin on the y-axis 690 and the second magnetometer transition 507, the sixth line 635 can provide relatively unpredictable position data. As described above, the fifth line 615 provides consistent and reliable position data over this range.Accordingly, consistent and reliable position data is guaranteed across the entire range from the origin on the y-axis 690 to the maximum path 509.
[0077] Fig. Figure 7 is a perspective view of a front fork 700. The front fork 700 can be used to mount a position sensing device described elsewhere herein, e.g., the one described with reference to Fig. The position detection device 200 described in sections 2-4. Fig. The front fork 700 shown generally includes a fork steerer tube 702 for attachment to a bicycle frame (for example, the frame 102 of Fig. 1) The fork steerer tube 702 is connected to a crown assembly 704. The crown assembly 704 transmits forces between other suspension forces to the fork steerer tube. For example, the crown assembly 704 transmits the steering torque of a rider input to a wheel (i.e., the front wheel 104 of the Fig. 1), which is connected to a wheel mounting section 710, and suspension forces via the fork steerer tube 702 to the rider. An upper assembly 706 is connected to the crown assembly 704. The upper assembly 706 may comprise one or more upper tubes, for example, those in Fig. The configuration shown in Figure 7 has two upper tubes. According to further embodiments, a configuration with a single tube can be provided. It should also be noted that although the upper assembly 706 and the crown assembly 704 are shown as separate components, they can be at least partially integral. For example, an inverted or upside-down fork configuration can have a one-piece crown and an upper assembly (not shown). A lower assembly 708 is movable relative to the upper assembly 706. The lower assembly 708 and the upper assembly 706 can each be referred to as a suspension element independently of one another. The relative movement of the lower assembly 708 and the upper assembly 706 serves to suspend the front fork 700. This relative movement of the lower assembly 708 and the upper assembly 706 can occur along an axis with a tube-in-tube configuration, as shown in Figure 7. Fig. 7 shown, or follow another path, for example with different connection arrangements that control the movement. Although according to the in Fig. In the embodiment shown in Figure 7, where the upper arrangement 706 is incorporated into the lower arrangement 708, it should be noted that the lower arrangement 708 could be incorporated into the upper arrangement 706, as is the case with inverted forks.
[0078] According to Fig. Figure 7 further comprises the front fork 700, comprising a damper section 712 and a spring section 714. The spring section 714 can be an air, metal-coil, or other spring configuration and is designed to support the weight of a rider. The damper section 712 is configured to control the movement of the spring section 714 and may be adjustable in various aspects. Although the damper section 712 and the spring section 714 are shown in separate legs of the front fork 700, it should be noted that the damper section 712 and the spring section 714 can also be combined in the same leg of the front fork 700, either in a single leg or in both legs. A brake mounting section 716 is also provided for receiving a brake, such as a mechanical or hydraulic brake caliper (not shown) acting on a brake disc (not shown).The brake mounting section 716 can be provided, as shown, on a single leg on the side of the damper section 712 or the spring section 714. A second brake mounting section (not shown) can also be provided on an opposite leg of the front fork 700.
[0079] Fig. Figure 7 further illustrates a first position sensing housing 718 and a second position sensing housing 720. The position sensing housings 718, 720 can be configured as in other embodiments described herein, for example as with reference to Fig. 2-4 and the position detection device 200 are described. The in Fig. The 7 section lines 8-8, 10-10, 11-11 and 12-12 shown schematically illustrate a section of the front fork, based on which various embodiments are now shown in Fig. 8-13 are described.
[0080] Fig. Figure 8 is a first embodiment of a sectional view of a position detection device 800 along the section line 8-8 in the schematic view of Fig. 7. The reference to Fig. The position detection device 800 described in Section 8 comprises a first leg 802 and a second leg 804. As shown, the first leg 802 can be a lower leg, for example, part of the [description of] the [description of] Fig. The lower arrangement 708 described in section 7. The second leg 804 can be an upper leg, for example, part of the arrangement described in section 708. Fig. The upper arrangement described in section 706. Fig. The section shown in Figure 8 can generally be referred to as the overlap region, in which the first leg 802 and the second leg overlap axially relative to a damper axis Q. According to the exemplary embodiment of Figure 8, the first leg 802 and the second leg 804 have a Fig. 8 each form a generally tubular configuration. The first leg 802, also referred to as the first tube, defines a first leg volume or a first tube volume. The second leg 804, also referred to as the second tube, defines a second leg volume or a second tube volume. As shown, the second leg 804 is located at least partially within the volume defined by the first leg 802. As already described with reference to the first telescopic component 202 and the second telescopic component 204 of Fig. As described in Figures 2-4, the second leg 804 is designed such that it moves telescopically relative to the first leg 802. As in Fig. As shown in Figure 8, the second leg 804 can, for example, move along the damper axis Q relative to the first leg 802. The damper axis Q can generally describe a translational axis, for example as shown in Figure 8. Fig. 2-4 described axis T described.
[0081] According to Fig. A detectable element 816 is provided. As described elsewhere herein, the detectable element 816 can have various configurations, including a permanent magnet configuration that generates a magnetic field. The detectable element 816 can also be referred to as a field-generating element. The detectable element 816 can be arranged at least partially within the volume defined by the first leg 802. For example, the Fig. 8 depicted detectable element 816 arranged in the volume defined by the first leg 802 and in the volume defined by the second leg 804.
[0082] The detectable element 816 can be fixed relative to the second leg 804 in various configurations. For example, the one in Fig. The detectable element 816 shown in Figure 8 is housed in a housing 818 of the detectable element and fixed by at least one holder 819 for the detectable element. The holder 819 for the detectable element can be an elastomeric element, a retaining ring, an adhesive, or various other fastening means. As shown in the present embodiment, a limiter 838 for the detectable element can also partially hold the detectable element 816 relative to the second leg 804. The limiter 838 for the detectable element can be an elastomeric element or a relatively rigid element and can further be configured to provide an alignment. For example, the illustrated limiter 838 for the detectable element can radially limit movement of the second leg 804 relative to the housing 818 of the detectable element.
[0083] As in Fig. As shown in Figure 8, the sensing element 816 can further be fixed relative to a body 842. The body 842 can also be referred to as a damper body, which controls at least a damping fluid. The body 842 is fixed relative to the second leg 804 and is accordingly movable along the damper axis Q with the second leg 804. A rod 840 is at least partially movable within the body 842. For example, the rod 840 can be moved within the body 842 by means of damping fluid in order to control a relative movement of the first leg 802 and the second leg 804. The rod 840 is fixed relative to the first leg 802.
[0084] At least one detector can be provided for detecting a magnetic field of the detectable element 816. For example, as in Fig. As shown in Figure 8, a first detection element 820 and a second detection element 822 are provided. The first detection element 820 and the second detection element 822 can be arranged outside the volume defined by the first leg 802 and the volume defined by the second leg 804. For example, the first detection element 820 and the second detection element 822 are arranged in a detection housing 830, as shown. The detection housing is arranged on an outer surface of the first leg 802, as shown. It is also conceivable that the detection housing could be integrated into the first leg 802, for example, in a detection housing cavity (not shown) of the first leg 802. As shown in Fig. As shown in Figure 8, the first detection element 820 and the second detection element 822 can generally be described as arranged on the outside and the detectable element can generally be described as arranged on the inside.
[0085] According to the in Fig. In the embodiment shown in Figure 8, the first detection element 820 and / or the second detection element 822 are shown on opposite sides of one or more elements of the detectable element 816. For example, the first detection element 820 and the second detection element 822 can each be described as lying on opposite sides of the first leg 802 from the detectable element 816. The first detection element 820 and the second detection element 822 can also each be described as lying on opposite sides of the second leg 804 from the detectable element 816. It should be noted that the first detection element 820 and / or the second detection element 822 can be provided in their own detection housing 830 or integrated into one or more elements and still be able to detect the detectable element 816 across one or more elements.For example, the first detection element 820 and / or the second detection element 820 can be integrally housed with the first leg 802 and operated in such a way that they detect a position of the detectable element 816 across the second leg 804.
[0086] The first sensing element 820 and the second sensing element 822 communicate with a processor 828 and a communication interface 832 and are powered by a power source 826. It should be noted that the first sensing element 820 and the second sensing element 822, as well as associated elements, can generally be configured as described with reference to related elements in other embodiments described herein. For example, the first sensing element 820 and the second sensing element 822, as well as associated elements, can generally be configured as described with reference to the first sensing element 220 and the second sensing element 222 in Fig. 2-4 described, and these descriptions may also apply to other embodiments, which are described below with reference to Fig. 9-14 are described. Although the in Fig. Figure 8 shows an embodiment with the first detection element 820 and the second detection element 822. It should be noted that any number of detection elements can be provided. For example, only the first detection element 820, a third detection element (not shown), or even further detection elements (not shown) can be provided.
[0087] Fig. Figure 9 is an embodiment of a sectional view of an arrangement 900 of a detectable element along the section line 8-8 in the schematic view of Fig. 7. The arrangement 900 of the detectable element can generally be used with other embodiments described herein, for example with the one described with reference to Fig. Position detection device 800 described in section 8. The one in Fig. The embodiment shown in Figure 9 provides a detectable element 916, which is housed in a casing 918 of the detectable element and is at least partially fixed by at least one holder for the detectable element. As shown, several holders 919 are provided for the detectable element. The several holders 919 for the detectable element can be threaded fastening elements. For example, a two-shell configuration of the casing 918 of the detectable element can be held together by the several holders 919 for the detectable element.
[0088] The in Fig. The detection element 916 shown in Figure 9 is fixed relative to a body 942. For example, the detectable element 916 can be held between the body 942 and the housing 918 of the detectable element. The body 942 can be positioned as above with reference to Fig. 8 described as being designed as a damper body. As in Fig. As shown in Figure 9, the body 942 includes a body opening 943, for example for receiving a rod or other damping element such as the one described with reference to Fig. Rod 840 described in section 8. The one in Fig. The body 942 shown in Figure 9 further comprises a body mounting interface 941. The body mounting interface 941 can be used to position various other components. For example, the body mounting interface can be connected to a rod seal assembly (not shown) to seal one or more damper components.
[0089] Fig. Figure 10 is a second embodiment of a sectional view of a position detection device 1000 along the section line 10-10 in the schematic view of Fig. 7. It should be noted that the position sensing device 1000 can generally employ all the features or relationships described elsewhere herein with reference to other exemplary position sensing devices and associated elements. The position sensing device 1000 can generally be provided in conjunction with an air spring displaceable along a spring axis S. The spring axis S can generally represent an axis along which a relative translation of components of the position sensing device 1000 takes place and generally corresponds to the descriptions with reference to the axis T in Fig. 2-4 correspond. As in Fig. As shown in Figure 10, the position sensing device 1000 can comprise a piston 1044 with a piston seal 1046 for sealing an air spring. For example, the piston seal 1046 can form an interface with an inner surface of a second leg 1004 to seal an air spring located therein. The second leg 1004 is movable along the spring axis S relative to a first leg 1002 to compress or extend this air spring.
[0090] Fig. Figure 10 further provides a detectable element 1016, which is fixed inside the second leg 1004. The detectable element 1016 shown is provided in a housing 1018 of the detectable element with a holder 1019 for the detectable element. The housing 1018 of the detectable element can generally contain the detectable element 1016. The holder 1019 for the detectable element can be an elastomeric element. For example, the holder 1019 for the detectable element can be designed to cushion or absorb impacts on the detectable element 1016.
[0091] Furthermore, a body 1042 is provided to accommodate the in Fig. The body 1042 serves to at least partially hold the detectable element 1016 shown in Figure 10. The body 1042 can be described as a spacer. The body 1042 holds the detectable element 1016 at a distance from one end of the second leg 1004 in the compression direction C. Accordingly, the body 1042 can be used to achieve a desired position for the detectable element and / or to protect the detectable element 1016 from being forced through. The body 1042 is held in the second leg 1004 by a limiter 1038 for the detectable element. The limiter 1038 for the detectable element can be, as shown, a retaining ring or another suitable holding element to hold the body 1042, the detectable element 1016, and other associated elements.
[0092] The exemplary embodiment of Fig. Assembly 10 further comprises a rod 1040, which is attached to the piston 1044. The rod 1040 is movable at its first leg 1002 relative to the detectable element 1016 and at its second leg 1004. Accordingly, a movement of the detectable element 1016 relative to the first leg 1002 can be used to determine a movement of the piston 1044 relative to the second leg 1004 and thus the compression and rebound of the air spring.
[0093] One or more detection elements may be provided to detect the position of the detectable element 1016. For example, in Fig. Figure 10 shows a first sensing element 1020 and a second sensing element 1022, which communicate with a processor 1028 and a communication interface 1032 and are powered by a power source 1026. The first sensing element 1020 and the second sensing element 1022 can generally be provided outside the air spring enclosed by the first leg 1002 and the second leg 1004. As in the embodiment of Fig. As shown in Figure 10, the first detection element 1020 and the second detection element 1022 are enclosed in a detection housing 1030 arranged on the first leg 1002. The first detection element 1020 and the second detection element 1022 can be operated to detect the position of the detectable element across the detection housing 1030, the first leg 1002 and the second leg 1004.
[0094] Fig. Figure 11 is a third embodiment of a sectional view of a position detection device 1100 along the section line 11-11 in the schematic view of Fig. 7. It should be noted that the position detection device 1100 can generally employ all the features or relationships described elsewhere herein with reference to other exemplary position detection devices and associated elements. As in Fig. As shown in Figure 11, the position sensing device 1100 has a combined brake and sensing housing 1130. The combined brake and sensing housing 1130 is fixed relative to a first leg 1102 and movable relative to a second leg 1104. Although the present embodiment of a combined brake and sensing housing 1130 is provided in conjunction with an air spring and is at least partially displaceable along the spring axis S, it should be noted that this embodiment can also be used with damper versions of a position sensing device.
[0095] The in Fig. The illustrated embodiment 1116 provides a detectable element 1116 within a housing 1118 of the detectable element. As shown, the detectable element 1118 is attached to a body 1142, which in turn is fixed in position relative to the second leg 1104. The detectable element 1116 is enclosed in the housing 1118 of the detectable element, which is at least partially fixed by a holder 1119 for the detectable element. The holder 1119 can be dimensioned and shaped such that it fixes the housing 1118 of the detectable element relative to the second leg 1102, for example, by an interference fit. The holder 1119 can be elastomeric to enable an interference fit and / or to protect the detectable element 1116 from vibrations.A limiter 1138 is provided for the detectable element, which can also be referred to as a spacer, and which can be operated as described in other air spring embodiments described herein. For example, the limiter 1138 for the detectable element can interact with a limiter 1148 for the lower end position, as in the example of . Fig. Figure 11 is shown to define a lower end position of the position detection device 1100.
[0096] According to Fig. In Figure 11, a rod 1140 is connected to the first leg 1102. The rod 1140 can be rigidly connected to the first leg 1102 or at least partially isolated from it. For example, the rod 1140 can be isolated from the first leg 1102 against vibrations by one or more isolating features. As shown in the present embodiment, a first isolator 1150 is provided below the rod 1140 in the compression direction C, and a second isolator 1152 is provided above the rod 1140 in the compression direction C. The first isolator 1150 and the second isolator 1152 can work together to dampen or otherwise control energy from spring inputs to the first leg 1102 before transmission to the rod 1140. It should be noted that a relative movement of the first leg 1102 and the second leg 1104 along the spring axis S would still occur regardless of an input from the first insulator 1150 and the second insulator 1152.Accordingly, the position detection device 1100 described herein would be operable to measure changes in the position of the second leg 1104 relative to the first leg 1102, which are made possible by the first insulator 1150 and / or the second insulator 1152.
[0097] Various other components of the position detection device may be provided, even if these are in Fig. 11 are not shown. For example, the combined brake and detection housing 1130 described above can house various detectors and associated elements. According to one embodiment, the combined brake and detection housing 1130 generally houses an arrangement of elements, e.g., those with reference to the detection housing 230 above with reference to Fig. 2-4 described. As in Fig. Figure 11 shows the first detection axis P1 and the second detection axis P2, which extend from the detection plane P, indicating detection elements (not shown) that can be operated to measure a position of the detectable element 1116.
[0098] Fig. Figure 12 is a fourth embodiment of a sectional view of a position detection device 1200 along the section line 12-12 in the schematic view of Fig. 7. It should be noted that the position detection device 1200 can generally employ all the features or relationships described elsewhere herein with reference to other exemplary position detection devices and associated elements. As in Fig. As shown in Figure 12, various elements of the position detection device 1200 are displaceable along the damper axis Q. For example, a first leg 1202 is movable along the damper axis Q relative to a second leg 1204. The second leg 1204 is displaceable in the compression direction C relative to the first leg 1202 within a travel range until the movement is stopped by a limiter 1248 for the lower end position.
[0099] According to the in Fig. In the embodiment shown in Figure 12, a detectable element 1216 is fixed in position relative to the second example 1204. The detectable element 1216 can be attached directly to the second leg 1204, e.g., by means of adhesive bonding. Alternatively, the detectable element 1216 can be, as in the embodiment shown in Figure 12, Fig. As shown in Figure 12, the detectable element is provided in a housing 1218. The housing 1218 of the detectable element is, in turn, attached to the second leg 1204. As shown in the present embodiment, a holder 1219 for the detectable element is provided to fix the housing 1218 of the detectable element relative to the second leg 1204. The holder 1219 of the detectable element can be an integral part of the second leg 1204, for example, a projection extending axially inward relative to the damper axis Q. The holder 1219 of the detectable element can also be designed as a removable element, for example, as a retaining ring or O-ring.
[0100] In the present embodiment, the second leg 1204 is movable along the damper axis Q relative to a rod 1240 attached to the first leg 1202. The rod 1240 is at least partially movable by a body 1242, which can also be referred to as an air spring body. The rod 1240 can be at least partially isolated from the first leg 1202. For example, the rod 1240 can be spring-loaded and / or damped relative to the first leg 1202. As in the embodiment of Fig. As shown in Figure 12, an insulator 1252 can be provided to isolate the rod 1240 against impacts or other forces acting on the first leg 1202. As shown, the insulator 1252 can be operated to absorb forces in the compression direction C and against the compression direction C on the first leg 1202 in a force transmission path to the rod 1240. The insulator 1252 can be provided as a plurality of elements, as shown with reference to the first insulator 1150 and the second insulator 1152 in Figure 12. Fig. 11 shown. According to the in Fig. In the embodiment shown in Figure 12, the insulator 1252 is provided as a single component which at least partially restrains the rod 1240 in order to control its movement in the compression direction C and against the compression direction C.
[0101] According to Fig. In the embodiment 12, a detection housing 1230 is provided outside the first leg 1202. The detection housing 1230 generally contains one or more detectors that detect the position of the detectable element 1216 within the first leg 1202. As shown in the present embodiment, the detection housing 1230 contains a first detection element 1220 and a second detection element 1222, each of which communicates with a processor 1228, a power source 1226, and a communication interface 1232. The communication interface 1232 can be wired or wireless and can be used to transmit data and / or command signals.For example, the 1232 communication interface can be used to transmit data indicating a position and / or to transmit command signals from processed position data, the command signals being used to command a change in the damper control of the suspension, the spring control of the suspension, or the control of one or more other bicycle components.
[0102] Fig. Figure 13 is a partial exploded view of an arrangement 1299 of the detectable element of the position detection device 1200 of Fig. 12. The arrangement 1299 of the detectable element can generally describe the detectable element 1216 and associated elements fixed relative to the detectable element 1216. As in Fig. As shown in Figure 13, the detectable element 1216 can be mounted along a mounting axis G with the housing 1218 of the detectable element. A cavity 1254 for the detectable element is provided in the housing of the detectable element 1218, wherein the cavity 1254 for the detectable element is dimensioned and shaped such that it can accommodate the detectable element 1216. A clearance 1256 for the detectable element can be provided as a corresponding feature to the detectable element 1216. As shown in the present embodiment, the clearance 1256 for the detectable element is provided in the second leg 1204. The clearance 1256 for the detectable element can interact with the housing 1218 of the detectable element to accommodate the detectable element 1216.The clearance 1256 for the detectable element can also serve to reduce the wall thickness of the second leg 1204, for example, to enable communication of a field of the detectable element 1216 across the second leg 1204. According to one embodiment, the clearance 1256 for the detectable element can be a broached feature in the second leg 1204.
[0103] According to Fig. In the second leg 1204, a limiter recess 1239 is provided. The limiter recess 1239 can be used to control impact forces. For example, the limiter recess 1239 can be configured to, upon contact with the limiter 1248 for the lower end position, as described above with reference to Fig. 12 described, to redirect or otherwise absorb impact forces. The limiter recess 1239 is shaped and dimensioned such that it can accommodate a limiter 1238 for the detectable element. The limiter 1238 for the detectable element can be any suitable feature that can hold the detectable element 1216 relative to the second leg 1204. As described in Fig. As shown in Figure 13, the limiter 1238 for the detectable element can be a retaining ring that can be removed for disassembly or maintenance.
[0104] Fig. Figure 14 is a perspective view of a position detection device 1400. The position detection device 1400 can be used with various bicycle components, e.g., the front fork 700 from Fig. 7, the front fork 108 of Fig. 1 or the rear suspension component 136 of Fig. 1. The in Fig. The position detection device shown in Figure 14 can generally have features that are described with reference to other embodiments, for example those described with reference to Fig. 2-4 described position detection device 200. As in Fig. As shown in Figure 14, the position sensing device 1400 has a sensing housing 1430. The sensing housing 1430 can be used to define an interior space for the position sensing device 1400, for example, by arranging components within the interior of the sensing housing 1430. As shown, the sensing housing 1430 is designed to be independent of other bicycle components; however, it should be noted that the sensing housing 1430 can be integrated into various bicycle components, for example, the front fork 700 of Fig. 7, the front fork 108 of Fig. 1 or the rear suspension component 136 of Fig. 1.
[0105] According to Fig. The position detection device 1400 further comprises a housing bracket 1431. The housing bracket 1431 shown is attached to the detection housing 1430, for example, by one or more fasteners (not shown) and / or an adhesive bond. The housing bracket 1431 can cooperate with the detection housing 1430 to seal the interior defined by the detection housing 1430. It should be noted that, according to some embodiments, the housing bracket 1431 can, for example, be formed as a single, integrated element with the detection housing 1430.
[0106] The in Fig. The position sensing device 1400 shown in Figure 14 can be configured for attachment to one or more components of a bicycle. For example, the position sensing device 1400 can be designed to be complementary in size and shape to one or more components. As already described, the position sensing device 1400 can be used to measure the position of the bicycle. Fig. The housing bracket 1431 shown in Figure 14 comprises a mounting element 1472. The mounting element 1472 is shown as a contour complementary to a bicycle component. However, it should be noted that the mounting element 1472 can be used as a fastener, adhesive, or other element for attaching the position sensing device 1400 to a bicycle component. As shown in Figure 1431, the housing bracket 1431 includes a mounting element 1472. The mounting element 1472 is shown as a contour complementary to a bicycle component. However, it should be noted that the mounting element 1472 can be used as a fastener, adhesive, or other element for attaching the position sensing device 1400 to a bicycle component. Fig. As shown in Figure 15, the mounting element 1472 comprises a mounting surface 1474. The mounting surface 1474 is dimensioned and shaped such that it can be attached to a bicycle component. According to the exemplary embodiment of Fig. 14 and Fig. 15 The mounting surface 1474 is designed for attachment to a generally tubular component or section. For example, the mounting surface 1474 can conform in size and shape to the contours of a bicycle front fork, such as the 700 front fork of Fig. 7 or the front fork 108 from Fig. 1 corresponds.
[0107] Fig. Figure 15 is a rotated perspective view of the position detection device 1400. Fig. 14. As in Fig. 14 and Fig. As shown in Figure 15, at least one alignment element can be provided. For example, a first alignment element 1476 can be provided to define or assist the alignment of the position sensing device 1400. According to one embodiment, the first alignment element 1476 interacts with a complementary alignment element (not shown) on the bicycle component to assist with alignment during installation. The first alignment element 1476 can serve to visually assist the alignment and / or physically hinder misalignment positions. Fig. 15. A second alignment element 1477 may be provided. The second alignment element 1477 may interact with a complementary alignment element (not shown) on the bicycle component. Additionally or alternatively, the first alignment element 1476 and the second alignment element 1477 may interact with each other and / or with an alignment tool (not shown) to visually and / or physically support the alignment.
[0108] According to Fig. 14 The position sensing device 1400 includes a cover element 1435. The cover element 1435 can be provided for user access, for example, to gain access to the interior of a battery housing 1433. According to one embodiment, the cover element 1435 can provide the only access to the interior of the sensing housing 1430, for example, if the sensing housing 1430 and the housing support 1431 are a single piece. Furthermore, it should be noted that the position sensing device 1400 can also be provided as a sealed unit that cannot be opened for maintenance purposes. However, as in Fig. As shown in Figure 14, the cover element 1435 can be removably coupled to the detection housing 1430, for example via one or more fastening elements 1437.
[0109] Fig. Figure 16 is a sectional view of the position detection device 1400. Fig. 14 along the section line 16-16. The position detection device 1400 can comprise one or more detection elements, for example as above with reference to Fig. 2-4 described. According to the Fig. In the embodiment shown in Figure 14, a first detection element 1420, a second detection element 1422, and a third detection element 1424 are provided. As already described, for example, with reference to Fig. As described in 2-4, the first detection element 1420, the second detection element 1422 and the third detection element 1424 can generally be configured to provide location data of a remotely detectable element (not shown), which is, for example, housed in a particular bicycle component.
[0110] According to Fig. In the first detection element 1420, the second detection element 1422, and the third detection element 1424 each communicate with a processor 1428. The processor 1428 is configured to process data from the first detection element 1420, the second detection element 1422, and the third detection element 1424, for example, to determine the position of a bicycle component, as described elsewhere herein. A communication interface 1432 communicates with the processor 1428. According to the illustrated embodiment, the processor 1428 includes a radio device that communicates with the communication interface 1432, which is configured as an antenna.
[0111] The first detection element 1420, the second detection element 1422, and the third detection element 1424 can be physically separated or otherwise isolated from various other components. For example, the first detection element 1420, the second detection element 1422, and / or the third detection element 1424 can be isolated from components that might cause electromagnetic interference. As shown in Fig. As shown in Figure 16, the communication interface 1432 is provided on a side of a printed circuit board (PCB) 1482 opposite the first sensing element 1420, the second sensing element 1422, and the third sensing element 1424. A power source 1426 is also provided on a side of the PCB 1482 opposite the first sensing element 1420, the second sensing element 1422, and the third sensing element 1424. The power source 1426 can be a battery, e.g., a button cell battery, as shown. The PCB 1482 can itself provide electromagnetic isolation against interference to the first sensing element 1420, the second sensing element 1422, and the third sensing element 1424 caused by the power source 1426 and / or the communication interface 1432.According to one embodiment, the PCB 1482 is configured to isolate the first detection element 1420, the second detection element 1422, and / or the third detection element 1424 from electromagnetic interference, for example, by means of a metallic shield. It should also be noted that further shielding elements may be provided. According to one embodiment, the first detection element 1420, the second detection element 1422, and the third detection element 1424 are arranged remotely from electromagnetically interfering elements.
[0112] According to Fig. A light source 1478 can be provided in the 16th embodiment. The light source 1478 can serve as a visual indicator for a user, for example, to confirm a status. According to various embodiments, the light source 1478 can be actuated to confirm an operating status, a coupling status, and / or a fault status. As shown in the present embodiment, a lens 1480 can be provided with the light source 1478. The lens 1480 can be any translucent element provided with the sensing housing 1430. For example, the sensing housing 1430 or a section thereof can be transparent or translucent. The lens 1480 can also be integrated into the light source 1478 and / or the sensing housing 1430 or a section thereof, for example, the lens 1480 shown in the 16th embodiment. Fig. The cover element 1435 shown in Figure 14 is integrated. The lens 1480 can be configured to seal with the detection housing 1430 to ensure light transmission while maintaining weather-resistant properties to protect elements within the detection housing 1430.
[0113] Fig. Figure 17 shows a further embodiment of a position detection device 1700. The position detection device 1700 described herein is provided in conjunction with a braking system. A detectable element 1716 can be fixed relative to various braking elements. As, for example, in Fig. As shown in Figure 17, the detectable element 1716 is attached to a brake element such as a master cylinder piston 1768. The master cylinder piston 1768 is displaceable along a cylinder axis M by a master cylinder 1762. Accordingly, the detectable element 1716, which is also referred to as the field-generating element, is movable with the master cylinder piston 1768. Detection can be carried out by a first detection element 1720 or further detection elements (not shown) relative to the detection plane P. For example, detection can be carried out parallel and / or perpendicular to the detection plane P, as shown in the embodiments in Figure 17. Fig. 2-4 described above. The cylinder axis M can be aligned relative to the detection plane P. For example, the cylinder axis M can be, as in Fig. 17 shown, running parallel to the recording plane P.
[0114] The in Fig. The embodiment shown in Figure 17 comprises a brake body 1758 and a brake lever 1760 pivotably mounted thereon, which can be operated to control the master cylinder piston 1768. The master cylinder piston 1768 comprises a first cylinder seal 1764 and a second cylinder seal 1766, each sealing between the master cylinder piston 1768 and the master cylinder 1762. As in the embodiment of Fig. As shown in Figure 17, the detectable element is arranged between the first cylinder seal 1764 and the second cylinder seal 1766 along the cylinder axis M. The main cylinder 1762 can be in constant or selective fluid connection with a reservoir 1770. According to the Fig. In the embodiment shown in Figure 17, the master cylinder 1762 is in selective fluid communication with the reservoir, the selective connection being controlled by the first cylinder seal 1764 and the second cylinder seal 1766. It should be noted that the detectable element 1716 may be configured to come into contact with brake fluid. For example, the detectable element 1716 may be made of a material that is selectively non-corrosive to brake fluid. Furthermore, it should be noted that the detectable element 1716 may be sealed against contact with brake fluid.
[0115] As already described, the detectable element 1716 can be detected by at least the first detection element 1720. The first detection element 1720 can be provided in conjunction with the brake body 1758, for example, integrated into or housed within it. According to the Fig. In the embodiment shown in Figure 17, the first detection element 1720 is provided in a detection housing 1730 outside the master cylinder 1762. The detection housing 1730 can be at least partially integrated into the brake body 1758. As shown in the present embodiment, the detection housing 1730 can be attached directly to the brake body 1758. The first detection element 1720 communicates with a processor 1728, a power source 1726, and a communication interface 1732, each of which can be configured according to related embodiments described elsewhere herein.
[0116] The position detection device 1700 is mounted on a handlebar (not shown), for example the handlebar 114 of Fig. 1. A steering axis H can be attached. The steering axis H can run parallel to the detection plane P. Alternatively, the steering axis H can be angled relative to the detection plane P, as in the embodiment shown in Fig. Figure 17 illustrates this. Actuation of the brake lever 1760 by a force exerted by a rider from the handlebar axis H causes a braking force to be generated by the movement of the hydraulic fluid with the master cylinder piston 1768. Movement of the master cylinder piston 1768 in the compression direction C or against the compression direction C can be detected by the first sensing element 1720 sensing the detectable element 1716. A signal indicating the position of the detectable element 1716 can then be transmitted via the communication interface 1732 to provide data on the braking process.
[0117] Fig. Figure 18 shows a front fork 1900 from the rear. In general, any single position sensing device described herein, or any combination thereof, can be used with the front fork 1900. As in Fig. As shown in Figure 18, the front fork 1900 comprises a fork steerer 1902 connected to a crown assembly 1904. The crown assembly 1904 is in turn connected to an upper assembly 1906, which is in turn connected to a lower assembly 1908. The lower assembly 1908 comprises a wheel mounting section 1910 and a brake mounting section 1916 for steering a front wheel (not shown).
[0118] The lower arrangement 1908 and the upper arrangement 1906 of Fig. 18 together define a damper section 1912 and a spring section 1914. For example, as in Fig. As shown in Figure 18, the spring section 1914 is arranged on one leg of the front fork 1900 and the damper section 1912 on another leg of the front fork 1900. However, it should be noted that the spring section 1914 and the damper section 1912 can be combined in a single leg.
[0119] The exemplary embodiment of Fig. Reference 18 further provides a position sensing housing 1918. The position sensing housing 1918 can be dimensioned and shaped such that it can accommodate any number of position sensing elements and associated components, as described in more detail below. The position sensing housing 1918 can be made at least partially of a material transparent to radio frequencies. For example, the position sensing housing 1918 can include an element made of a polymer, for example nylon, to enable wireless transmission between the interior of the position sensing housing 1918 and the outside. As in the embodiment of Fig. As shown in Figure 18, a user interface 1927 can also be provided on the position sensing housing 1918, for example, to allow a user to switch on, off, initiate coupling, or otherwise control the operation of a position sensing device housed therein. The user interface 1927 can be configured to maintain a sealed environment for the position sensing housing 1918. For example, the position sensing housing 1918 can be sealed from the lower arrangement 1908, and the user interface 1927 can be a sealed button that communicates mechanically or electrically with the interior of the position sensing housing.
[0120] Fig. Figure 19 is a side view of the 1900 front fork. As in Fig. As shown in Figure 19, a power source 1926 can be provided outside the position sensing housing 1918. The power source 1926 can, for example, be a removable battery that is detachably attached to the position sensing housing 1918. The power source 1926 and / or the position sensing housing 1918 can have one or more sealing features to maintain a sealed environment for the position sensing housing 1918 and / or the front fork 1900 in general.
[0121] As in the exemplary embodiment of Fig. As shown in Figure 19, the position sensing housing 1918 can be arranged behind the front fork 1900 relative to the direction of travel A. This mounting position makes it easier to protect the position sensing housing 1918 from obstacles and / or debris. Additionally or alternatively, this position can facilitate communication with other electronic components of a bicycle and / or offer aerodynamic advantages. As shown in Fig. As shown in Figure 19, the power source 1926 can extend rearward from the position sensing housing 1918 in a direction opposite to the direction of travel A. This arrangement of the power source 1926 offers similar advantages to the arrangement of the position sensing housing 1918. Additionally, the power source 1926 can be easily removed and replaced in such a position.
[0122] Fig. Figure 20 is a sectional view of the front fork 1900 along the section line 20-20 in Fig. 18. Further details regarding the damper section 1912 are in Fig. 20 shown with this sectional view. As in Fig. As shown in Figure 20, the damper section 1912 comprises a damper shaft 1961, which at least partially controls a compression assembly 1960 and extends between the upper assembly 1906 and the lower assembly 1908. The compression assembly 1960 generally controls the flow restriction when the front fork 1900 is compressed in the compression direction C and can be adapted to the dimensions and preferences of the user. Furthermore, it should be noted that the compression assembly 1960 could be configured to additionally or alternatively control the restoring forces in a direction opposite to the compression direction C.
[0123] According to Fig. In the present embodiment, the damper shaft 1961 is fixed relative to the upper arrangement 1906 and movable relative to the lower arrangement 1908. However, it should be noted that the reverse configuration could also be provided, for example by relocating the position sensing housing 1918 and associated components to the upper arrangement 1906. According to the present embodiment of Fig. 20, in which a floating piston 1958 is housed in the lower arrangement 1908, the position detection housing 1918 is arranged such that it detects a movement of the floating piston 1958, as described in more detail below.
[0124] Fig. Figure 21 is an enlarged sectional view of the front fork from 1900, as shown in section 21 in Fig. 20 shown. As in Fig. As shown in detail in Figure 21, the floating piston 1958 is movably housed in a damper body 1957. According to some embodiments, the section of the damper body 1957 in which the floating piston 1958 is housed can be referred to as the IFP housing, with reference to the alternative designation "internal floating piston" for the floating piston 1958. The floating piston 1958 is movable in response to the compression and rebound of the front fork 1900, for example by movement of the in Fig. 20 damper shafts shown, 1961. As in Fig. As shown in Figure 21, fluid from a first oil chamber 1962, for example, can be moved via a rebound assembly 1959 into a second oil chamber 1963. The rebound assembly 1959 can be configured as a stack of adjusting shims, as shown, or otherwise. When fluid, for example, suspension oil, is displaced into the second oil chamber 1963, the floating piston 1958 must also move. The floating piston 1958 can move freely downwards by compression of fluid in the air chamber 1964, for example, along the damper axis Q. The air chamber 1964 is pressurized to ensure that the floating piston 1958 controls the behavior of the fluid in the damper section 1912, for example, to prevent cavitation, while the floating piston 1958 can still move proportionally to the compression and rebound of the front fork 1900.
[0125] As already described in the embodiment above, the floating piston 1958 can be configured to move proportionally to the movement of the front fork 1900. More precisely, the floating piston 1958 can move directly proportionally to the relative movement between the upper assembly 1906 and the lower assembly 1908. That is, there is a constant or nearly constant ratio between the movement of the upper assembly 1906 relative to the lower assembly 1908 and the movement of the floating piston 1958 and the movement of the damper body 1957. According to some embodiments, this ratio can be approximately 10:1 between the movement of the suspension and the movement of the IFP. Accordingly, the position measurement of the floating piston 1958 can generally be correlated with the position of the front fork 1900 in the compression direction C.Furthermore, it should be noted that the detection of the floating piston 1958 may be important independently, for example to determine whether the front fork 1900 is being actuated beyond a threshold value or at all, instead of being transported or moved.
[0126] According to Fig. 21 As described elsewhere herein, one or more detection elements and detectable elements may be provided. As shown, a detectable element 1965 is provided in the floating piston 1958. The detectable element 1965 is held relative to the floating piston 1958 by a limiter 1966 for the detectable element. As shown, the limiter 1966 for the detectable element is a retaining ring, but could be any retention feature, including adhesive or magnetic retention features. The detectable element 1965 may be a permanent magnet or another suitable detectable construction, which may depend on the type of detection element(s) implemented.
[0127] The in Fig. The embodiment shown in Figure 21 provides a first sensing element 1920 spaced apart from a second sensing element 1922. It should be noted, however, that only the first sensing element 1920 can be used, for example, when, due to the relatively short travel of the floating piston 1958 along the damper axis Q in relation to the relatively long travel of the front fork 1900, an adequate range and resolution are generally achieved. According to the present embodiment, the first sensing element 1920 and the second sensing element 1922 are each arranged on a PCB 1982. The PCB 1982 can be configured with any number of elements, as described elsewhere herein. As shown, the PCB 1982 includes a processor 1928 and a communication interface 1932.The 1932 communication interface can be a radio device, for example for receiving and sending radio signals to an external device.
[0128] As in Fig. As shown in Figure 21, the power source 1926 can be held removable relative to the front fork 1900. For example, the power source 1926 can be removablely attached to the position sensing housing 1918 by means of a battery lock 1937. The present embodiment provides a rotatable configuration of the battery lock 1937, which is attached to the position sensing housing 1918 by means of a locking pin 1933. A first end of the power source 1926 is selectively engaged by rotating the battery lock 1937, and an oppositely arranged end of the power source 1926 engages the position sensing housing 1918 with a power source positioning feature, which is shown as a battery tab.It should be noted that according to this and other embodiments, the power source 1926 can be interchangeable with one or more power sources on other bicycle components, for example gear shifters, suspension controls, seat posts, power meters or other electronic bicycle components.
[0129] Fig. Figure 22 is another sectional view of the front fork 1900 along the section line 22-22 in Fig. 19. The view in Fig. Figure 22 illustrates the spring section 1914 of the front fork 1900 more clearly. It should be noted that further embodiments described herein can be combined with the described embodiments of the present front fork 1900. For example, the front fork 1900 can be modified with one or more sensing elements and sensable elements on the fork chassis. According to such an embodiment, data can be collected that represent a chassis movement (i.e., a movement of the upper assembly 1906 relative to the lower assembly 1908) and an IFP movement (i.e., a movement of the floating piston 1958 relative to the damper body 1957). Since this data is assumed to be in a fixed and predictable relationship to each other, any deviation can serve as an indication of a fault condition, for example, a fluid loss in the damper section 1912.
[0130] Fig. Figure 23 is a side view of a shock absorber 2000, in which any of the position detection devices described herein may be used. Fig. Figure 24 is a second side view of the 2000 shock absorber and is shown together with Fig. 23. The shock absorber 2000 generally comprises a first mounting section 2010 and a second mounting section 2011. As shown, the first mounting section 2010 and the second mounting section 2011 each have an eyelet configuration, but they can also be configured differently to accommodate any type of bicycle frame element. Movement of the first mounting section 2010 relative to the second mounting section 2011 along an axis T provides suspension for a bicycle to which the shock absorber 2000 can be attached.
[0131] According to the present embodiment, the first mounting section 2010 is connected to a cap assembly 2004 as part of an outer assembly 2006. The second mounting section 2011 is connected to a damper body 2057 as part of an inner assembly 2008. The inner assembly 2008 is telescopically movable within the outer assembly 2006 along the axis T. The inner assembly 2008 and the outer assembly 2006 can each be referred to separately as suspension elements. The outer assembly 2006 includes an air reservoir 2002 in which the damper body 2057 can be received. Within the outer assembly 2006 is a spring section 2014, which is designed to resist the compression of the shock absorber 2000. Although the spring section 2014 shown and described herein is an air spring configuration, it should be noted that, according to this embodiment, a coil spring could also be used.A damper section 2012 is also provided and designed to control the compression and expansion of the shock absorber 2000.
[0132] The in Fig. 23 and Fig. Figure 24 further illustrates a position sensing housing 2018. The position sensing housing 2018 can generally be designed like any other position sensing housing described herein. As shown, the position sensing housing 2018 is arranged near the damper body 2057 on the outer assembly 2006. As described in more detail below, this exemplary arrangement of the position sensing housing can enable a compact design and reliable position sensing.
[0133] Fig. Figure 25 is a sectional view of the shock absorber 2000 along the section line 25-25 in Fig. 24. As in Fig. As shown in Figure 25, a damper shaft 2061 is provided to partially control the fluid movement between a first oil chamber 2062 and a second oil chamber 2063. When fluid is moved from the first oil chamber 2062 into the second oil chamber 2063 via an adjusting plate arrangement 2059, a compressible fluid in an air chamber 2064 expands and moves a floating piston 2058, so that the total volume between the first oil chamber 2062 and the second oil chamber 2063 remains constant when the damper shaft 2061 is retracted from this combined volume. The damper shaft 2061 is sealed by an internal seal 2045 of the sealing head.
[0134] According to the in Fig. In the embodiment shown in Figure 25, a sealing head assembly 2044 is provided to hold the inner seal 2045 and an outer seal 2046 of the sealing head. The inner seal 2045 of the sealing head seals the second oil chamber 2063 against the spring section 2014 (shown as an air spring). The outer seal 2046 of the sealing head seals a positive spring volume against a negative spring volume in the spring section 2014. The inner seal 2045 and the outer seal 2046 of the sealing head work together to enable the spring section to compress air and function as a suspension spring.
[0135] As in Fig. As shown in Figure 25, a detectable element 2065 is provided with the sealing head assembly 2046. The detectable element 2065 can be a permanent magnet or another suitable detectable element, as described elsewhere herein. The detectable element 2065 is fixed relative to the sealing head by a limiter 2066 for the detectable element, which can be a retaining ring or another suitable fastening element described herein. The detectable element 2065 can also be formed integrally with the sealing head assembly 2044, for example by co-molding.
[0136] Various position detection housings and their internal components are described elsewhere herein and could be used in the Fig. The embodiment shown in Figure 25 is used. As shown in the present embodiment, a first detection element 2020 and a second detection element 2022 are provided, which are powered by an internal power source 2026.

[0137] Fig. Figure 26 is a side view of a shock absorber 2100 in which any of the position detection devices described herein may be used. Fig. Figure 27 is a second side view of the shock absorber 2100 and is shown together with Fig. 26 described. The present embodiment can generally be designed with regard to spring and damper components like the shock absorber 2000 described above. As in Fig. 26 and Fig. As shown in Figure 27, the shock absorber 2100 can be mounted using a first mounting section 2110 and a second mounting section 2111. The first mounting section 2110 is connected to an outer assembly 2106, which includes a cap assembly 2104, an air reservoir 2102, and a spring section 2114. The second mounting section 2111 is connected to an inner assembly, which includes a damper body 2157 and a damper section 2112.
[0138] The in Fig. The embodiment shown in Figure 26 further provides a reservoir body 2183, which is sometimes also referred to as an external reservoir or piggyback. The reservoir body 2183 according to the present embodiment is configured to receive an IFP, as explained elsewhere herein and, in particular, with reference to the present embodiment, as detailed below. Fig. 28 and Fig. 29 described. The illustrated reservoir body 2183 is connected to a first position sensing housing 2118, which is adjacent to a power source 2126. As described below, one or more additional or alternative position sensing housings may be provided, which are, for example, connected to the power source 2126 and adjacent to the reservoir body 2183.
[0139] Fig. Figure 28 is a sectional view of the shock absorber 2100 along the section line 28-28 in Fig. 26. Fig. Figure 29 is an enlarged sectional view, as in section 29 in Fig. 28 is shown, and is presented together with Fig. 28 described. The views in Fig. 28 and Fig. Figure 29 shows a floating piston 2158, which is housed in the reservoir body 2183. The floating piston 2158 moves relative to increases or decreases in the fluid volume of a first oil chamber 2162 and is pressure-assisted by the gas pressure in an air chamber 2164. The movement of the oil via an adjusting shim arrangement 2159 into and out of the first oil chamber 2162 represents the compression of the shock absorber 2100. The floating piston 2158 can therefore be used as a substitute for the overall movement of the shock absorber 2100 in a similar manner to that described above with reference to the front fork 1900.
[0140] According to Fig. 29 is a detectable element connected to the floating piston 2158, held by a limiter 2166 for the detectable element, as shown. A first detection element 2120 is provided on a PCB 2182 in the first position detection housing 2118. A processor 2128, a user interface 2127, and a communication interface 2132 are also provided, as described elsewhere herein. As shown in this view, the first detection element 2120 has a first detection axis P1 that overlaps with, but is not concentric with, a reservoir axis R representing the stroke of the floating piston 2158. Accordingly, the first detection axis P1 can run parallel to the stroke of the floating piston 2158 along the reservoir axis R.
[0141] Fig. Figure 30 is another sectional view of the shock absorber 2100 along the section line 30-30 in Fig. 27. As in Fig. As shown in Figure 30, a second position sensing housing 2119 can be provided. The second position sensing housing 2119 can be provided in addition to or as an alternative to the first position sensing housing 2118. According to one embodiment, the first position sensing housing 2118 uses its first sensing element 2120 and the second position sensing housing 2119 uses its second sensing element 2122 to jointly measure a position of the detectable element 2165. In this embodiment, it is noteworthy that the first sensing element 2120 has a first sensing axis P1 that is angularly, for example orthogonally, offset from a second sensing axis P1 of the second sensing element 2122.
[0142] The first acquisition element 2120 and the second acquisition element 2122 can, when used together, share other elements such as the power source 2126, the communication interface 2132, and / or the processor 2128. Alternatively, additional such elements can be provided in duplicate for the second acquisition element 2122. As shown in Fig. As shown in Figure 30, the power source is attached next to the second sensing element 2122 using a battery lock 2137, a locking pin 2133 and a power source positioning feature 2131, which are similar to those described above with reference to the front fork 1900.
[0143] In the partial section view of Fig. Figure 30 shows a section of a sealing head assembly 2144, which includes an outer seal 2146 of the sealing head. This configuration can generally be similar to that described above with reference to the shock absorber 2100. For example, the present embodiment includes a second oil chamber 2163, which is partially sealed by the sealing head assembly 2144, so that, upon compression of the shock absorber 2100, it is moved via the adjusting shim assembly 2159 into the first oil chamber 2162. With reference to Fig. Item 30 specifies a 2145 coil spring as a negative spring. It should be noted that a coil negative spring can be used instead of or in addition to an air negative spring, just as coil and air positive springs are interchangeable.
[0144] Fig. Figure 31 is a flowchart describing a method for position detection. It should be noted that the exemplary methods described herein can be applied to each of the aforementioned embodiments of the position detection device 200, 800, 1000, 1100, 1200, 1400, 1700. In Figure 1801, a detectable element 216, 816, 916, 1016, 1116, 1216, 1716 is moved. For example, a detectable element 216, 816, 916, 1016, 1116, 1216, 1716 can be moved along a travel path over a travel range, for example, along an axis G, M, Q, S, T relative to one or more other elements. This movement can define an infinite number of positions. According to one embodiment, a detectable element 216, 816, 916, 1016, 1116, 1216, 1716 is movable between a first position and a second position.
[0145] According to the in Fig. In the 31 illustrated procedure, a first output is generated at 1802. The first output can be generated by a first detection element 220, 820, 1020, 1220, 1420, 1720. The first output indicates a movement of the detectable element 216, 816, 916, 1016, 1116, 1216, 1716 from the first position to the second position. At 1803, a second output is generated. The second output can be generated by a second detection element 222, 822, 1022, 1222, 1422. The second output differs from the first output, for example, by indicating a measurement from a different position. The second output indicates a movement of the detectable element 216, 816, 916, 1016, 1116, 1216, 1716 from the first position to the second position.
[0146] The in Fig.Procedure 31, illustrated, continues with 1804, determining position data from the first and second outputs. This determination can be performed using a processor 228, 828, 1028, 1228, 1428, or 1728. The procedure can then proceed to transmit processor outputs representing position data. For example, the processor 228, 828, 1028, 1228, 1428, or 1728 can transmit this data, via a communication interface 232, 832, 1032, 1232, 1432, or 1732, to a portable device, cloud storage, or various components of a bicycle for analysis or control, as described elsewhere herein.
