Description

[Technical Field]

[0001] Field

[0001] This disclosure relates to an oarlock for locking oars to a rowing vessel when the oarlock is installed on the rowing vessel or rowing simulator, and is particularly, but not exclusively, applicable to an oarlock that can be installed on a rigging pin of a rowing vessel or rowing simulator. [Background technology]

[0002] background

[0002] In rowing, to assess rowing performance, it is often useful to measure the force a rower applies to an oar or oars, and the angular displacement of those oars from a reference data point, while the rower is rowing. Such rowing force and angular displacement measurements are typically made with on-board oarlocks on both sides of the rowing vessel, or with the rower positioning an oar or oars.

[0003] It is known that an oarlock can include components for measuring a force or forces applied to the oarlock by the oar and the angular displacement of the oarlock when the oar is used by the rower during a rowing stroke. It is known that a microelectromechanical systems ("MEMS") gyroscope can be utilized to measure the angular displacement of the oarlock.

[0004] However, measurements from MEMS gyroscopes drift over time, and therefore there is a need in the art for an improved or alternative oarlock. Summary of the Invention [Means for solving the problem]

[0010] Detailed Description of the Embodiments

[0031] An aspect provides an oarlock for locking oars to a rowing vessel when the oarlock is installed on the rowing vessel or rowing simulator, the oarlock including a housing, an angle measuring device, and a resetter.

[0011]

[0032] Another aspect provides a method for displaying rowing data, the method including reviewing a target for a measurement category and measurement data belonging to that category, determining a difference between the target and the measurement data, and displaying one of a plurality of types of display categories based on the difference.

[0012]

[0033] FIG. 1 illustrates an embodiment of a closed oarlock 1 (i.e., an oarlock shown in a closed position) for locking oars to a rowboat when the oarlock 1 is installed on the rowboat. The oarlock 1 includes a housing 2, which itself includes a cover 5 and an arm 4 having a latch 3, the latch 3 being shown in the closed position. The cover 5 is configured to receive a cartridge 10 (not shown), which in turn is configured to receive a rigging pin 6 (not shown). The oarlock 1 further includes a top cap 8 that retains the cartridge 10 within the cover 5 and secures the oarlock 1 to the rigging pin 6. A separate resetter magnet 13 can be seen below the housing 2, which will be described later.

[0013]

[0034] In this embodiment, the latch 3 is a magnetic latch that can be maintained in a closed position by a magnetic fastener. However, in alternative embodiments, it is contemplated that the latch 3 may not be a magnetic latch. For example, in another embodiment, it is contemplated that the latch 3 can simply be clipped into place without the use of a magnet.

[0014]

[0035] FIG. 2 shows the oarlock 1 when the latches 3 shown in FIG. 2 are in an open position, and therefore shows an embodiment of an unlatched oarlock 1 (ie, the oarlock 1 shown in the unlatched position).

[0015]

[0036] 3A shows an embodiment of an open oarlock 1. After the latch 3 has been moved to the open position, the arm 4 may be swung open as shown in FIG.

[0016]

[0037] 3B and 3C show alternative views of the open oarlock 1 of FIG. 3A.

[0017]

[0038] FIG. 4A shows an embodiment of an oarlock 1 mounted on a mounting pin 6. First, the resetter magnet 13 is mounted on the mounting pin 6 so that the oarlock 1 can be positioned at the appropriate height relative to the rower. Next, the cover 5 and cartridge 10 (not shown) receive the mounting pin 6 as described above. That is, the oarlock 1 is placed on the mounting pin 6 via the cover 5 and cartridge 10 until the cartridge 10 is positioned over the resetter magnet 13. Next, the top cap 8 is placed over the cover 5, securing the oarlock 1 to the mounting pin 6. From there, the rower may further secure the oarlock 1 to the mounting pin 6 by placing a spacer below the resetter magnet 13 to fill the space between the resetter magnet 13 and the raised portion 7 of the mounting pin 6, and placing a spacer above the top cap 8 to fill the space between the top of the mounting pin 6. The rower may adjust the height of the oarlock 1 on the rigging pin 6 by adding or removing spacers as needed.

[0018]

[0039] Alternatively, it is envisioned that the resetter magnet 13 may be located on the oarlock 1 on the mounting pin 6, i.e., on the top cap 8, or alternatively, in any other location fixed relative to the oarlock 1 from which the cartridge 10 can perform the reset function, as described below.

[0019]

[0040] 4B-4D show alternative views of the oarlock 1 installed on the rigging pin 6 of FIG. 4A.

[0020]

[0041] 5A shows an embodiment of a cartridge 10. The cartridge 10 is installable in and removable from the cover 5 of the oarlock 1. The cartridge 10 includes a support 11, which itself includes other components described below, and a force loading plate 18.

[0021]

[0042] In this embodiment, the support 11 is a printed circuit. However, those skilled in the art will appreciate that the support 11 may be in the form of a separate, dedicated circuit device that is not entirely integrated into the cartridge 10.

[0022]

[0043] Figure 5B shows an alternative view of cartridge 10 of Figure 5A. From this perspective of cartridge 10, it can be seen that support 11 is equipped with an interface 17 that can be connected to an image capture or data logging device (not shown), or the like, which can provide power, data transfer and storage capabilities, and processing capabilities to cartridge 10, as described below.

[0023]

[0044] 6 shows an exploded view of an embodiment of a cartridge. As shown, support 11 includes angle measurement device 12, processor 15, analog-to-digital converter 16 ("ADC"), and magnet sensor 19. As mentioned above, cartridge 10 also interfaces with resetter magnet 13 (not shown) and includes interface 17 (not shown). Additionally, cartridge 10 includes at least two force-measuring devices 14 positioned below force load plate 18. Resetter magnet 13 and magnet sensor 19 are collectively known as resetters 13, 19. In another embodiment, it is envisioned that cartridge 10 may also include a communication device and a power source.

[0024]

[0045] In this embodiment, the angle measuring device 12 includes an angular displacement sensor (or angular displacement measuring device) configured to measure the angular displacement of the oarlocks 1 from a datum or reference point, and a planar acceleration sensor (or planar acceleration measuring device) configured to measure the planar acceleration of the oarlocks 1 from the datum or reference point. However, in alternative embodiments, it is envisioned that the angle measuring device 12 includes only an angular displacement sensor or only a planar acceleration sensor. In this embodiment, the angle measuring device 12 is a MEMS gyroscope.

[0025]

[0046] When the planar acceleration sensor measures the planar acceleration of the oarlock 1, the planar acceleration sensor measures the frequency, magnitude, and direction of the force sensed by the oarlock 1. For example, upon completion or release of a rowing stroke by a rower, the planar acceleration sensor is configured to detect how much vibration or rocking of the oars and oarlocks 1 occurs, for example, by measuring the frequency, magnitude, and direction of the force sensed by the oarlock 1 in a plane perpendicular to the rigging pin 6 or a plane collinear with the centerline of the rowing vessel. Advantageously, the data measured by the planar acceleration sensor may indicate how efficiently and effectively the rower and their skill level performed the completion or release of the rowing stroke. A rowing stroke that ends with a particularly high reading captured by the planar acceleration sensor may indicate that the rower is a beginner.

[0026]

[0047] In another embodiment, it is envisioned that one or more planar acceleration sensors in one or more housings positionable on the rigging arms, for example, throughout the rowing vessel independently of the oarlocks 1, measure the vibration and oscillation of the oarlocks 1 closest to the planar acceleration sensor and / or the combined vibration or oscillation of the collective oarlocks 1 transmitted through the rowing vessel. When all the combined vibration or oscillation of the collective oarlocks 1 transmitted through the rowing vessel and measured by the one or more planar acceleration sensors, data may be obtained regarding damage to the rowing vessel caused by the collective end or release of a rower's rowing stroke in the rowing vessel.

[0027]

[0048] The resetters 13, 19 are configured to determine a zero point or offset to which the value measured by the angle measuring device 12 can be reset before the angle measuring device 12 measures another angular displacement of the oarlock 1 during a rowing stroke by the rower or another rowing stroke.

[0028]

[0049] In this embodiment, the magnet sensor 19 is configured to determine an offset for the angle measuring device 12 based on a resetter magnet 13, which includes a pair of oppositely polarized magnets (not shown), so that the zero point at which the angle measuring device 12 measures angular displacement can be reset or offset and, advantageously, compensate for drift. As the rower rows from start to finish, the magnet sensor 19 passes the resetter magnet 13 and resets the measurements taken by the angle measuring device 12 to zero if a maximum or minimum magnetic field is detected by the magnet sensor 19. Alternatively, as the rower rows from start to finish and the oar passes the resetter magnet 13, the measurements taken by the angle measuring device 12 can be noted and offset, and the zero point can be derived based on the offset. It is envisioned that other devices have the capability to reset the angle measuring device 12.

[0029]

[0050] In this embodiment, the resetter magnet 13 compensates the oarlock 1 on the rigging pin 6 of the rowing vessel to ensure automatic detection of the side of the rowing vessel on which the oarlock 1 is to be installed. Due to the orientation of the installation of the resetter magnet 13 on the rigging pin 6, a pair of oppositely polarized magnets (not shown) of the resetter magnet 13 enables measurements made by the angle measuring device 12 to always reflect values ​​relating to the appropriate side of the rowing vessel.

[0030]

[0051] The force measuring device 14 is configured to measure all forces exerted by the rower's oar on the oarlock 1 while the rower is rowing. That is, the force measuring device 14 can capture all forces for each stroke the rower makes with the oar, and the plane of the force measurements made by the force measuring device 14 is always perpendicular to the rigging pin 6. Advantageously, the force measuring device 14 can capture all angles of each stroke the rower makes with the oar in a plane perpendicular to the faces of the oarlock 1 and the rigging pin 6, so measurements can be made without the need for interpolation between the different angles the rower's oar makes with respect to the oarlock 1 and the rigging pin 6. The measurements captured by the force measuring device 14 are transmitted to the ADC 16, which then transmits the converted measurements to the processor 15.

[0031]

[0052] In this embodiment, the force measuring device 14 is a load cell. Although it is typically envisaged that there will be multiple load cells in the oarlock 1, those skilled in the art will appreciate that in alternative embodiments there can be only one load cell.

[0032]

[0053] In a preferred embodiment, the force-measuring devices 14 are positioned vertically, one above the other, as shown in Figure 6. In the embodiment shown in Figure 6, each force-measuring device 14 is capable of making an independent measurement of the rotational twist of the oar sleeve throughout the entire rowing stroke. By detecting the relative amount of force on each force-measuring device 14, the rotational twist of the oar sleeve, and therefore the oar, can be inferred.

[0033]

[0054] In this embodiment, the angle measuring device 12, the force measuring device 14, and the magnet sensor 19 take measurements at a rate of 100 Hz, however, those skilled in the art will recognize that different frequencies (e.g., faster or slower than 100 Hz) can be used.

[0034]

[0055] The processor 15 is configured to receive and process measurements and data captured by the angle measuring device 12, the magnet sensor 19, and the force measuring device 14. For example, the processor 15 can process measurements captured by the angle measuring device 12 and the force measuring device 14 and communicate such processed measurements to the mobile device via the communications device. Alternatively, the processor 15 can transmit measurements captured by the angle measuring device 12, the force measuring device 14, and the magnet sensor 19 and communicate such measurements to the image capture device via the interface 17 for processing.

[0035]

[0056] In such a setup, the image capture device may be coupled to the top of the rigging pin 6, with the processor 15 providing measurements from the angle measuring device 12 and the force measuring device 14 to the image capture device via the interface 17. By communicating such measurements to the image capture device via the interface 17, which then processes and communicates with the mobile device, the oarlock 1 advantageously avoids signal transmission losses and interference from water and other rowing vessel components.

[0036]

[0057] The image capture device can record images of the rower as he or she rows, and can then transmit such image data, or the angle and force measurements described above, directly to a mobile device or alternatively to a collector (e.g., a hub or router mounted on the rowing boat) that provides a reliable known position within the rowing boat and collects data and network transmission signals from the oarlocks 1, image capture devices, or data loggers mounted on the rowing boat, which then communicate with the mobile device. Additionally, the image capture device is configured as a data logger that stores measurements received from cartridge 10 via interface 17 in memory.

[0037]

[0058] This embodiment of AllLock 1 uses a wired connection for communication between AllLock 1 and the image capture device. However, it is contemplated that other suitable wireless communication technologies may be used. For example, one skilled in the art will recognize that alternative embodiments of AllLock 1 may use Zigbee, WiFi, or Bluetooth instead.

[0038]

[0059] The power source provides power to the different components of cartridge 10 (e.g., angle measurement device 12, force measurement device 14, processor 15, and communication device). It is envisioned that the power source may be a rechargeable battery, a replaceable battery, or any other type of power supply. It is further envisioned that an external device (e.g., an image capture device) may also provide power to cartridge 10 via interface 17.

[0039]

[0060] FIG. 7A shows an embodiment of an exploded view of the cartridge 10 relative to the oarlock 1 such that the cartridge 10 can be installed in and removed from the cover 5 of the oarlock 1 .

[0040]

[0061] FIG. 7B shows an alternative exploded view of cartridge 10 relative to oarlock 1 of FIG. 7A.

[0041]

[0062] 8A shows an embodiment of the cartridge 10 and resetter magnet 13 mounted on the mounting pin 6, without showing the cover 5 and oarlock 1. When the cartridge 10 is mounted on the cover 5 of the oarlock 1 and the cover 5 accommodates the mounting pin 6, the mounting pin 6 passes through the cartridge 10, as shown in FIG. 8A.

[0042]

[0063] FIG. 8B shows an alternative view of the cartridge 10 installed on the mounting pin 6.

[0043]

[0064] 9 shows an embodiment of the angle measurement device 12 and resetter magnet 13 positioned around the mounting pin 6, not showing the rest of the cartridge 10, the cover 5 and the oarlock 1. As mentioned above, the resetter magnet 13 includes a pair of oppositely polarized magnets 13a, 13b.

[0044]

[0065] As mentioned above, the mobile device may have measurements made by the angle measuring device 12 and the force measuring device 14 transmitted to the mobile device via the oarlock 1 by the communication device of the cartridge 10 or by an image capture device coupled to the cartridge 10 via the interface 17. For a given rower, the mobile device may receive measurements from two oarlocks 1 or two image capture devices in the case of sculling, and from one oarlock 1 or one image capture device in the case of sweep rowing. For example, a given rower in a sculling boat may have one oarlock 1 measuring the angles and forces resulting from the rower's bow oar (or the right side of the rowboat as viewed from the stern to the bow of the rowboat) and another oarlock 1 measuring the angles and forces resulting from the rower's port oar (or the left side of the rowboat as viewed from the stern to the bow of the rowboat). The measurements captured by the forward oarlock 1 and the port oarlock 1 may then be transmitted to a mobile device directly or via an image capture device on the respective forward or port side of the rowing vessel.

[0045]

[0066] When the mobile device receives measurements from Alllock 1 or the image capture device, it may format the measurements and present them on the user interface 30 .

[0046]

[0067] 10A shows an example of a user interface 30 for an eight-part rowing boat on a mobile device according to an embodiment. The user interface 30 provides a display category 34 for a given measurement category 33 for each rower 32 (e.g., Jazz, Amy, Eddie, etc.) at each rowing position 31 (e.g., 1b or bow seat number 1, 2s or stroke seat number 2, 3b or bow seat number 3, etc.). Instead of the oarlocks 1 simply transmitting raw or real-time measurements captured by the angle measuring devices 12 and force measuring devices 14, the processor 15 or image capture device can process the measurements captured by the angle measuring devices 12 and force measuring devices 14 and transmit such processed data for display on the user interface 30.

[0047]

[0068] For a given measurement category 33, a user of a mobile device or mooring display device may view, at a glance, data regarding rower performance in an easily summarizable format. The measurement category 33 includes "FG force," which corresponds to the force on the fore and port oarlocks 1 as measured by each oarlock's force measuring device 14; "FG angle," which corresponds to the angle of each oarlock 1 relative to the fore and port oarlocks 1 as measured by each oarlock's angle measuring device 12; "FG synchronicity," which corresponds to a measure of how synchronized the rowers 32 are with each other in terms of the closeness of rowing stroke timing between each rower 32; and "FG duration," which corresponds to a measure of the duration of time per rowing stroke for each rower 32. Within each measurement category 33, instead of displaying measurements collected at each of the fore and port oarlocks, it is envisioned that parameters of one or more measurement categories 33 may be displayed. For example, in the "FG Force" measurement category 33, columns in the Display category 34 may correspond to the rower's 32 force per kilometer, peak force, force during the catch or start of the rowing stroke. It is envisioned that other measurement category 33 parameters may be calculated from measurements taken by the angle measuring device 12 and the force measuring device 14. Further measurement categories 33 such as the rower's 32 body temperature or heart rate data received from a separate integrated sensor or device are also envisioned.

[0048]

[0069] A user of the mobile device or tethered display device may first input target values ​​for measurement categories 33 into the user interface 30, where the target values ​​are numerical values ​​that benchmark the performance of each rower 32. For example, for the "FG angle" measurement category, a user of the mobile device or tethered display device (e.g., a coach) may input a target value corresponding to a theoretically ideal angle measurement for the catch angle. Next, the user of the mobile device or tethered display device may input high and low tolerance levels for measurement category 33 into the user interface 30, where the tolerance level is a numerical value referenced to the target value and represents an acceptable deviation from the target value. Then, as the rowers 32 row, measurements taken by the angle measurement device 12 for each rower's 32's catch angle during their rowing stroke (i.e., the angle at which the output portion of their stroke begins) are compared to the target value input by the user of the mobile device or tethered display device. The display category 34 for each rower 32 indicates the difference between each rower's 32's measured catch angle and target values ​​entered by the mobile device user for both the catch angle and the finish angle (i.e., the angle at which the output portion of the rower's stroke ends), as represented by the left and right columns of the display category 34, respectively. For example, a first type of display category 35a, shown with dashed lines, may indicate that, for a particular rowing stroke, the rower is making the catch at an angle that is on target or within a small tolerance level from the target. A second type of display category 35b, shown with dotted lines, may indicate that, for a particular rowing stroke, the rower is making the catch at an angle that is within an expected tolerance level from the target. A third type of display category 35c, shown with solid lines, may indicate that, for a particular rowing stroke, the rower is making the catch at an angle that exceeds the tolerance level from the target. Other ranges of tolerance levels from the target and different types of display categories 35 (e.g., different colors for each type of display category 35) are envisioned.For example, in an embodiment, a first type of display category 35a may be shown in green, a second type of display category 35b may be shown in amber, and a third type of display category 35c may be shown in red.

[0049]

[0070] 10A , the user interface 30 shows the selection of the Force Measurement Category 33 tab, and a mobile device user (e.g., a coach) may view each rower 32's performance relative to the force applied by each rower 32 to the rower's oars and conversely to each rower's oarlock 1, represented by display categories 34 having a given type of display category 35. The mobile device user may have set a force target for each oarlock 1 for each rower 32 by benchmarking measurements taken by the force measurement device 14, determine the difference between the force of the given rower's 32 rowing stroke and the force target, and display the corresponding type of display category 35. Alternatively, as described above, each column of a display category may correspond to a parameter of a different measurement category 33. For example, in FIG. 10A, rower 32 (Ellie) sitting in rowing position 31 (7s) has a parameter in the force measurement category 33 of the first oarlock 1 that is outside the range of the target value to the vicinity of the tolerance level, and a parameter in the force measurement category of the second oarlock 1 that is on target.

[0050]

[0071] In Figure 10B, the user interface 30 shows additional detail regarding the display categories 34 compared to Figure 10A in the form of a target display 36. The target display 36 indicates whether the force measurements for a given rower 32's rowing stroke are greater than or less than the target value entered by the mobile device user, indicated by an up or down arrow, respectively. As can be seen in Figure 10B, the rower 32 (Issy) sitting in rowing position 31 (5s) has a parameter in the force measurement category 33 for the first oarlock 1 that is greater than the target value and outside a range near the target value and an acceptable level, and a parameter in the force measurement category 33 for the second oarlock 1 that is greater than the target value and outside a range near the target value and an acceptable level.

[0051]

[0072] In addition to variable directional target indicators 36, such as up and down arrows, different target indicators 36 are also contemplated. For example, in FIG. 11A , the delta target indicator 36 may show a difference from target in decimal form that corresponds to the difference from target displayed in the display category 34 having the type of display category 35. Additionally, the actual target indicator 36 may show a measurement of the rowing stroke for a particular rower 32 in decimal form that is displayed in the display category 34 having the type of display category 35. In some embodiments (e.g., the embodiment shown in Figures 11A and 11B), if target indicators 36 are available, if the measurement is within the target's acceptable range or tolerance, neither target indicator 36 may be shown in display category 34, or a symbol may be shown in display category 34, as shown in the left and right columns of display category 34 for rower 32 (Andy) sitting in rower position 31(8b) in Figures 11A and 11B, and in the left column of display category 34 for rower 32 (Amy) sitting in rower position 31(2s) in Figure 11B.

[0052]

[0073] 11A illustrates the user interface 30 showing the selection of the Synchronization Measurements category 33 tab, where a mobile device user (e.g., coach) may view each rower 32's performance against the Synchronization Measurements category 33 parameters of each rower's 32 rowing stroke as compared to other rowers 32 and the rowing targets represented by display categories 34 having a given type of display category 35. A Delta Target display 36 is shown in FIG. 11A, where the number in each display category 34 represents units of time away from the synchronization target.

[0053]

[0074] 11B illustrates the user interface 30 showing the selection of the Synchronized Measurements category 33 tab, where a mobile device user (e.g., coach) may view each rower 32's performance against the Synchronized Measurements category 33 parameters of the rowing stroke of each rower 32 as compared to other rowers 32 and the rowing goals represented by display categories 34 having a given type of display category 35. Like FIG. 10B, FIG. 11B illustrates a variable direction target display 36.

[0054]

[0075] From the user interface 30, a mobile device user may cycle through measurements taken at different times or with different rower 32 rowing strokes to see how a particular rower 32 is performing over time or at a particular time.

[0055]

[0076] As described above, the image capture devices can record images of the rowers as they row, and then transmit such image data directly to a mobile device or alternatively to a collector on the rowing vessel, which can then communicate with the mobile device. In an eight-piece rowing vessel (i.e., a vessel carrying eight rowers), an image capture device can be installed on each rigging pin 6, and the image data recorded by each image capture device can be stored on each image capture device and then transmitted to the same mobile device or collector, which can then communicate such image data to the mobile device. A user of the mobile device may then use user interface 30 to view synchronized image captures (i.e., video) of each rower from the port and bow sides of the rowing vessel.

[0056]

[0077] Additionally, as discussed above, it is contemplated that the oarlock 1 may transmit the raw or real-time measurements captured by the angle measuring device 12 and the force measuring device 14 to a mobile device or image capture device where they are processed by the processor 15 or image capture device. When received by the mobile device, a user of the mobile device may view such data on the user interface 30 in the form of an alternative to a graph charting measurements over time. It is contemplated that a user of the mobile device may view such measurement data simultaneously with image data captured by the image capture device, allowing visualization of such measurement data as it was collected during the rower's rowing stroke.

[0057]

[0078] FIG. 12 illustrates an embodiment of a method 40 for displaying rowing data.

[0058]

[0079] The method includes a first method step 41 of receiving a target of measurement category 33 .

[0059]

[0080] In a second method step 42, measurement data belonging to a measurement category 33 is received.

[0060]

[0081] In a third method step 43, the difference between the target and the measured data is determined.

[0061]

[0082] In a fourth method step 44, one of a plurality of types of display categories 35 is displayed based on the difference between the target and the measured data.

[0062]

[0083] Unless the context requires, either by clear words or necessary implication, in the following claims and the foregoing specification of the invention, the terms "comprise" or variations such as "comprises" or "comprising" are used in an inclusive sense, i.e., to specify the presence of stated features but not to exclude the additional presence of further features in various embodiments of the invention.
