[0034] The inventors have identified problems with conventional fitness machines or exercise machines currently known in the art, particularly with the conventional input devices used to control the operation of such machines. Known conventional input devices for controlling exercise machines include, but are not limited to, push-button switches, capacitive touch switches, slide switches, selector switches (e.g., knobs or levers with multiple positions), levers (e.g., limit switches), and / or other switching mechanisms. In the example of an elliptical trainer, the input device is typically used to adjust the resistance experienced and / or switch electronic exercise settings. Other uses of conventional input devices for exercise machines include, for example, those used to adjust the resistance, incline, and / or stride length of rowing devices, treadmills, stair climbers, cross trainers, elliptical trainers, or upright or recumbent stationary bikes. It should be recognized that these are merely examples, and other features of exercise machines known in the art can also be adjusted via input devices.

[0035] The inventors recognize that, particularly for exercise machines, conventional input devices tend to be damaged or otherwise fail, and are especially susceptible to the effects of liquids (e.g., beverages, cleaning agents, water, and / or sweat) during operation, particularly during user exercise due to heavy use and / or operation. For example, some conventional input devices known in the art have moving parts, seams, and other joints, and therefore have an inherently limited lifespan. This is further exacerbated for conventional input devices in exercise machines used in commercial environments (e.g., fitness centers), where these input devices are exposed to greater usage and, consequently, greater wear and malfunction. Similarly, the inventors have determined that any ingress of water, sweat, and / or dirt can cause malfunctions in the moving or adjacent parts of a conventional input device (and / or any internal electrical components contained therein), leading to input device failure. Replacing these conventional input devices is often expensive and requires installation by a technician rather than the exercise machine owner, adding further costs and longer downtime. Some conventional input devices may be combined with or embedded in other components (e.g., the panel of an inseparable input device), making it impossible to replace the faulty input device without replacing the entire component.

[0036] Through experimentation and development, the inventors have invented a novel input module with a force-sensitive component that solves or at least reduces the severity of one or more problems associated with the aforementioned conventional input devices.

[0037] Figure 1An example exercise machine 10, including an elliptical trainer, is depicted. The elliptical trainer is similar to those currently known in the art, but incorporates one or more input modules 30 according to this disclosure. The exercise machine 10 is configured to allow a user to perform one or more exercise movements. The exercise machine 10 has a frame 11 that supports components of the exercise machine 10 (described below) and further supports the user thereon. One or more ground-engaging wheels and / or support legs 12 are coupled to the frame 11 and configured to prevent the exercise machine 10 from tilting. In use, the user stands on a pedal 13, which is connected to an elongated leg member 14 and is movable to rotate a crank assembly 15. An arm member 16 is pivotally coupled to the leg member 14, and the user grips the arm member 16 during operation. Thus, the user can apply forces (e.g., pushing or pulling forces) to the arm member 16 and / or leg member 14 with their arms and legs, respectively, thereby rotating the crank assembly 15 and exercising.

[0038] Resistance device 90 is coupled to crank assembly 15 and contained within housing 25. Resistance device 90 is configured to resist rotation of the crankshaft about an axis (not shown) within crank assembly 15, and thus control the resistance applied to the exercise movement. Resistance device 90 may include, for example, eddy current or magnetic or friction braking devices and / or others. The user can adjust resistance device 90 by adjusting resistance settings via display interface 19 and / or input component 20, thereby changing the resistance applied by resistance device 90. Display interface 19 may be a capacitive touchscreen display or an LED display panel. Display interface 19 may include mechanical and / or tactile buttons.

[0039] Display interface 19 is mounted to and extends generally upward from bridge 17, which is connected to frame 11. Arm member 16 may also be pivotally connected to bridge 17. Bridge 17 may include one or more cup holders and trays for holding the user's personal items. Optionally, bridge 17 supports handle 18, which may be selectively gripped by the user, and input module 30 is positioned within a space at least partially defined by handle 18. Input module 30 is configured to face the user on exercise machine 10 and has one or more input buttons or areas 31 for receiving or adjusting operating settings of exercise machine 10, such as resistance settings and / or tilt settings. Handle 18 may optionally include one or more sensors (e.g., heart rate sensors and / or others) that provide user feedback signals to control system 100. Note that control system 100 is schematically depicted as part of display interface 19. Control system 100 processes feedback signals to display information to the user, customize exercise programs, adjust the tilt of leg member 14, and / or adjust the resistance applied by resistance device 90.

[0040] Now go to Figures 2-3An enlarged view of another example exercise machine 10 (which is an upright stationary bicycle in this illustrated example) is shown, and exercise machine 10 includes an example input module 30 according to this disclosure. Note that each example exercise machine 10 of this disclosure may include one or more features and / or components (or a portion of) the other example exercise machines 10 described herein. For example, Figure 2 The example exercise machine 10 depicted may include reference Figure 1 The described exercise machine 10 includes one or more features and / or components. In another example, Figure 1 The exercise machine 10 described herein may include reference Figure 2 The described exercise machine includes one or more features and / or components. Further note that similar components shown in the accompanying drawings may be designated using the same reference numerals; however, it should be understood that the use of the same reference numerals for features and / or components in the various examples of this disclosure should not be construed as indicating that features and / or components with similar reference numerals must be identical. Features and / or components with similar reference numerals may have varying characteristics. For example, Figure 2 The frame 11 may include a seat post, which is not included in the frame. Figure 1 In the frame 11 shown.

[0041] The exercise machine 10 includes a frame 11 having a seat post (not shown) supporting a seat (not shown) for a user to sit on, pedals for a crank assembly (not shown), a display interface (not shown), a tray 22 for the user to place personal items, and handlebars 23 that the user can optionally grip. The handlebars 23 include a plurality of sensors / input devices 24, and an input module 30 is located near the central portion of the handlebars 23. Note that although the example input module 30 according to this disclosure is depicted on an exercise machine 10 that is an upright stationary bike, the input module 30 can be used on other exercise machines 10, such as elliptical trainers, rowing machines, treadmills, stair climbers, recumbent stationary bikes, and others.

[0042] Typically, the input module 30 is oriented toward and / or towards the user and includes one or more input buttons or areas 31 for a force-sensitive sensor assembly 50 (further described herein) that the user can engage. Based on the user's engagement with the sensor assembly 50, the input module 30 provides one or more signals (e.g., control signals) to the control system 100, which in turn can adjust the operation of the exercise machine 10 (e.g., adjust resistance and / or incline), display information to the user, customize exercise programs, and so on. Figure 2 As shown, the sensor assembly 50 has three input areas 31 (see also...) Figure 4The exercise machine 10 includes an input switch 32, both of which are surrounded by a protective cover 33. During normal operation of the exercise machine 10, the protective cover 33 is reinforced by a reinforcing plate 70 (further described herein; see also...). Figure 13 The guard 33 is securely attached to the frame 11 and / or the handle 23. However, during the assembly and / or maintenance of the exercise machine 10, the guard 33 can be detached from the handle 23 and / or the frame 11.

[0043] Figures 4-9 The other components of the housing 33, sensor assembly 50, and input module 30 are described in more detail. See reference for details. Figures 4-6 The shield 33 includes a first opening 35A and a second opening 35B. Figure 4 The sensor assembly 50 receives the input switch 32 in the first opening 35A. Figure 2 The first opening 35A is partially received in the second opening 35B. The first opening 35A is partially formed by the lip 36. Figure 6 Defined by a lip edge 36, which extends inwardly from the inner peripheral surface 37 of the shield 33, the lip edge 36 has an upper lip edge surface 38. The shield 33 also includes a first surface 39 surrounding the opening 35A, and the first surface 39 lies in a plane parallel to and offset from another plane where the lip edge surface 38 is located. In some examples, the lip edge surface 38 is below the first surface 39. A second surface 40 surrounds the first surface 39, and a transition surface 43 ( Figure 6 The transition surface 43 extends between the first surface 39 and the second surface 40. Note that... Figure 7 The second surface 40 is depicted having a round edge 45 adjacent to the transition surface 43. The bottom first side 41 of the opening 35A ( Figure 6 This allows the cable to pass through it to reach the sensor assembly 50. The user accesses the sensor assembly from the upper second side 42 (opposite to the first side 41) of the opening 35A. Figure 6 ) Connect sensor assembly 50.

[0044] Sensor assembly 50 in Figures 5-7 The image is depicted as a split view, thus illustrating the placement of the sensor assembly 50 relative to the shroud 33. Typically, the sensor assembly 50 includes a cover layer 53 and a light guide plate 51 (described further herein). When the sensor assembly 50 is in the opening 35A, the bottom 59 of the light guide plate 51 rests on the lip surface 38. In some examples, when the light guide plate 51 rests on the lip surface 38, the top 58 of the light guide plate 51 is flush with the first surface 39 of the shroud 33 (see [link to image]). Figures 8-9 An adhesive or bonding layer (not shown) can bond the light guide plate 51 to the lip surface 38. Once the light guide plate 51 is correctly positioned in the first opening 35A (as described above), the cover layer 53 is attached to the top 58 of the light guide plate 51 and the first surface 39 of the shield 33 (see...). Figure 6 and Figure 4 Therefore, the cover layer 53 is typically located in a plane and provides a generally smooth top surface 55 for the cover layer 53.

[0045] The cover layer 53 is formed of any suitable material (e.g., plastic, polyester, glass, and polycarbonate materials) and is coated such that the markings (e.g., the numbers "1", "2", "3") are visible on the top surface 55 of the cover layer 53. In one example, the markings are coated white, while the rest of the cover layer 53 is coated black. In this example, the markings are at least translucent and thus allow light from the light guide plate 51 to pass through (as further described herein). Note that in some examples, the bottom side of the cover layer 53 is coated white to accommodate one or more light sources 49, such as monochrome or RGB light-emitting diodes (LEDs). Figure 7 The reflection of emitted light.

[0046] The input region 31 of the input module 30 is typically defined as the area around the top surface 55 surrounding each mark, for example, see Figure 4 The dashed lines in the diagram schematically depict the input area 31 on the top surface 55 surrounding each digit "1", "2", and "3". The overlay layer 53 includes a peripheral lip 54. Figure 6 The peripheral lip 54 extends laterally (e.g., vertically) away from the top surface 55. The peripheral lip 54 adheres to the transition surface 43 of the shield 33, thereby forming a liquid-impermeable seal between the transition surface 43 and the cover layer 53 to prevent debris and / or fluid from entering the opening 35A. Furthermore, the peripheral lip 54 serves to block light that might otherwise leak through the seam between the cover layer 53 and the transition surface 43.

[0047] The light guide plate 51 includes a printed circuit board assembly (PCBA) 52 and a light guide assembly 60. The PCBA 52 has a top surface 56 to which one or more light sources 49 are coupled, and the light sources 49 extend from the top surface 56. The light sources 49 are configured to emit light, and the top surface 56 is preferably reflective and / or coated white to reflect the light emitted by the light sources 49. The PCBA 52 also includes an opposite bottom surface 57 to which electrical components such as capacitors, inductors, resistors, diodes, sensors, and transistors are coupled. Note that... Figure 10 The bottom side of the shield 33 is depicted, wherein the bottom surface 57 of the PCBA 52 is visible through the opening 35A. The PCBA 52 includes a module for input 30 (see...). Figure 4 Sensor 48 in each input area 31 Figures 10-11 ),and Figure 11The PCBA 52, light guide assembly 60, and cover layer 53 are depicted as transparent, thereby exemplarily illustrating that each sensor 48 can interact with one of the input areas. Figure 4 Alignment with corresponding markings. Sensor 48 is configured to sense strain forces acting on one or more components (e.g., PCBA 52) of input module 30. For example, sensor 48 is capable of sensing strain forces in PCBA 52 that are applied by the user to input area 31 ( Figure 4 Caused by the application of one or more forces. Cover layer 53, light guide assembly 60, and PCBA 52 (see...) Figure 5 The components are connected together such that a force applied by the user to one of the input areas 31 of the cover layer 53 is transmitted to the PCBA 52, and thus the PCBA 52 bends or deforms due to the force applied to the input area 31. The bending or deformation of the PCBA 52 results in strain forces in the PCBA sensed by the sensor 48. The sensor 48 generates an analog signal, and the control system 200 analyzes and / or calculates the corresponding sensed strain forces. Note that in some examples, the sensor 48 generates digital signals. The signal corresponding to the sensed strain forces is transmitted to the control system 100. Figure 1 The following provides a further description of sensor 48 and control system 100. Sensor 48 can be any suitable sensor 48 capable of sensing bending or deformation of PCBA 52 and / or sensing strain forces in PCBA 52. In a non-limiting example, sensor 48 is a piezoresistive sensor or a piezoresistive pressure sensor. In a non-limiting example, sensor 48 is a commercially available and publicly available piezoresistive sensor manufactured by New Degree Technology (part number: MSK10-P6 or MSK10-P8).

[0048] As described above, the light guide assembly 60 is connected to the top surface 56 of the PCBA 52 (see...). Figure 5 The light guide assembly 60 is used to diffuse the light emitted by the light source 49, so that the light uniformly illuminates the cover layer 53 and / or the markings on the cover layer 53. That is, the light emitted by the light source 49 is received in the light guide assembly 60, which diffuses the light and allows it to pass in a direction toward the cover layer 53, thereby uniformly illuminating the markings defined by the cover layer 53 (see...). Figure 4 ), and reduce or eliminate bright spots or uneven light intensity of the light illuminating the covering layer 53 and / or the markings.

[0049] Figure 12 An exploded view of the example light guide assembly 60 is depicted in more detail. The light guide assembly 60 has a first side 61, an opposite second side 62, and a plurality of light guides 63. In some examples, the number of light guides 63 corresponds to the input region 31 of the input module 30. Figure 4The number of light guides 63 is specified (e.g., three light guides 63 for three input regions 31). Each light guide 63 is formed of a suitable transparent or translucent material such as plastic, glass, and others, and each light guide 63 has a material thickness through which light propagates. In some examples, each light guide 63 includes at least one notch 66 in which the light source 49 is received (see...). Figure 7 Thus, light emitted by light source 49 enters light guide 63, and light guide 63 diffuses the light. In some examples, a diffuser layer 64 is coupled to light guide 63 and configured to further diffuse the light as it propagates from light guide 63 toward the mark in cover layer 53. In some examples, diffuser layer 64 comprises a diffuser material coated or sprayed onto light guide 63. In other examples, diffuser layer 64 comprises the top surface of light guide 63, and the top surface is etched (e.g., laser etched) to “roughen” the top surface and promote light diffusion. The inventors have found that light guide 63 and / or diffuser layer 64 advantageously diffuse light from light source 49. Therefore, sensor assembly 50 is configured to uniformly illuminate the mark in cover layer 53 ( Figure 4 This allows for aesthetically illuminating of the markings without the "hot spots," grit effect, and / or uneven illumination commonly found in conventional devices such as membrane switches.

[0050] The light guide assembly 60 includes a barrier member 65 extending between adjacent light guides 63, thereby physically isolating the light guides 63 from each other and preventing light diffused by one light guide 63 from propagating into the other light guide 63. The barrier member 65 is preferably formed of black foam. The barrier member 65 and the light guides 63 are joined together by a pair of adhesive layers (i.e., a first adhesive layer 67 and a second adhesive layer 68). The first adhesive layer 67 also bonds a first side 61 of the light guide assembly 60 to the top surface 56 of the PCBA. Figure 5 Furthermore, the second adhesive layer 68 can also bond the second side 62 of the light guide assembly 60 to the cover layer 53.

[0051] Now go to Figures 13-14 The input module 30 and the protective cover 33 are depicted removed from the exercise machine 10, thereby exposing the reinforcing plate 70 of the frame 11 attached to the exercise machine 10. Note that in this example, the sensor assembly 50 is transparently depicted as being attached to the protective cover 33, and the input switch 32 is depicted as being attached to the reinforcing plate 70. The inventors recognize that a user of the exercise machine 10 may grab the protective cover 33 ( Figure 2 The sensor 48 ( ) is located on both sides and further forces (e.g., torsional forces) are applied to it. These forces may affect the sensor 48 ( ) Figure 10 The sensed strain causes sensor 48 to generate a signal indicating that the user has engaged one or more input regions 31. Figure 4Therefore, the inventors have sought to prevent non-input area engagement forces from being sensed by the sensor 48. These forces are those applied to the exercise machine 10 and / or input module 30, rather than those directed by the user to the engagement input area 31 (e.g., the torsional force on the guard 33 when the user grips the handle 23, the rocking force applied to the exercise machine 10 when the user performs an exercise). The inventors have developed a reinforcing plate 70 that reduces or prevents non-input area engagement forces from being sensed by the sensor 48. The reinforcing plate 70 isolates the sensor assembly 50 from the guard 33 and frame 11. The reinforcing plate 70 is securely attached to the frame 11 and / or handle 23, and includes a channel 71 through which wires reach the sensor assembly 50. Figure 14 The shield 33 includes one or more first mounting devices 44 (e.g., screws, threaded holes) that are mounted to corresponding second mounting devices 72 (e.g., screws, threaded holes) on the reinforcing plate 70. Therefore, the non-input area engagement force applied to the shield 33 is transmitted to the reinforcing plate 70 via the mounting devices 44, 72, thereby isolating the sensor assembly 50 from certain non-input area engagement forces and preventing the sensor 48 ( Figure 10 This generates an error signal caused by the user engaging the shield 33.

[0052] Figure 15 This includes an example input module 30 with three input areas 31 and another example input module 30 with six input areas 31. The input module 30 with six input areas 31 may include reference... Figures 2-14 The three-region input module 30 depicted in the diagram describes multiple components and features. Figure 15 In the example shown, the input module 30, with six input areas 31, has a function for adjusting the exercise machine 10 ( Figure 1 The three input areas 31 for the inclination and the three input areas 31 for adjusting the resistance of the exercise machine 10. Figure 1 ).

[0053] Figures 16-20 Other example sensor components 50 according to this disclosure are depicted. Figures 17-18 The electronic communication tail 47 is depicted, which is connected to the bottom surface 57 of the PCBA 52. Figure 10 This connects PCBA52 electronically to the control system 100. Figure 1 ).

[0054] Figure 21 An example control system 100 for controlling and adjusting the operation of the exercise machine 10 is depicted. As described above, the user can communicate with the control system 100 via a display interface 19, input device 24, and / or input module 30. Figure 1It provides user input to control and adjust the operation of the exercise machine 10 (e.g., adjust the resistance).

[0055] Certain aspects of this disclosure are described or depicted as functional and / or logical block components or processing steps that can be performed by any number of hardware, software, and / or firmware components configured to perform specified functions. For example, some embodiments employ integrated circuit components, such as memory elements, digital signal processing elements, logic elements, lookup tables, or others, configured to perform various functions under the control of one or more processors or other control devices. Connections between functional block components and logical block components are merely exemplary and can be direct or indirect, and may follow alternative paths.

[0056] In some examples, the control system 100 communicates with each of one or more components of the exercise machine 10 via a communication link 101, which can be any wired or wireless link. The control system 100 is able to receive information and / or control one or more operational characteristics of the exercise machine 10 and its various subsystems by sending and receiving control signals via the communication link 101. In one example, the communication link 101 is a Controller Area Network (CAN) bus (e.g., an I2C serial communication bus); however, other types of links may also be used. It will be appreciated that the scope of the connection and the communication link 101 can actually be one or more shared connections or links between some or all of the components in the exercise machine 10. Furthermore, the line of communication link 101 is intended only to indicate that the various control elements can communicate with each other and does not represent an actual wiring connection between the various elements, nor does it represent a unique communication path between the elements. Furthermore, the exercise machine 10 can include various types of communication devices and systems, so the communication link 101 shown can actually represent various different types of wireless and / or wired data communication systems.

[0057] The control system 100 may be a computing system including a processing system 102, a memory system 104, and an input / output (I / O) system 103 for communicating with other devices, such as input devices 108 (e.g., display interface 19, input device 24, and / or input module 30) and output devices 107 (e.g., resistance device 90), any of which may or may alternatively be stored in the cloud 109. The processing system 102 loads and executes an executable program 105 from the memory system 104, accesses data 106 stored in the memory system 104, and instructs the exercise machine 10 to operate as described in further detail below.

[0058] The processing system 102 may be implemented as a single microprocessor or other circuitry, or distributed across multiple processing devices or subsystems that collaboratively execute the executable program 105 from the memory system 104. Non-limiting examples of the processing system include general-purpose central processing units, dedicated processors, and logic devices.

[0059] Memory system 104 may include any storage medium readable by processing system 102 and capable of storing executable program 105 and / or data 106. Memory system 104 may be implemented as a single storage device or distributed across multiple storage devices or subsystems that collaboratively store computer-readable instructions, data structures, program modules, or other data. Memory system 104 may include volatile and / or non-volatile systems and may include removable and / or non-removable media implemented using any method or technology for storing information. Storage media may include non-transitory and / or transient storage media, including random access memory, read-only memory, magnetic disks, optical disks, flash memory, virtual and non-virtual memory, magnetic storage devices, or any other medium that can be used to store information and is accessible by an instruction execution system.

[0060] In the example above, sensor 48 is configured to sense strain in PCBA52 when a user presses input area 31 on cover 53 (see [link]). Figure 5 and Figure 10 Sensor 48 then transmits a signal corresponding to the strain (e.g., the number of grams of force experienced by PCBA 52) to control system 100 via control system 200. Note that this signal can be an analog signal or a digital signal.

[0061] Note that in the example described below, the signal from sensor 48 is transmitted to the control system 100 of the exercise machine 10 for processing. The control system 100 of the exercise machine 10 also controls components of the exercise machine 10 and sensor assembly 50 based on the signal. However, in other examples, sensor assembly 50 includes a sub-control system or its own control system that processes the signal from sensor 48 and then relays the processed signal to the control system 100 of the exercise machine 10 for further processing, sending control signals to other components of the exercise machine 10 (e.g., resistance devices), and / or sending control signals to other components of sensor assembly 50 (e.g., light source 49).

[0062] The following describes an example method 600 for operating the exercise machine 10 (see also...) Figure 24 ), including an input area 31 based on user engagement (e.g., pressing). Figure 4 )Control light source 49( Figure 7The resistance is applied by the lighting and / or resistance device 90. In step 601, the user may wish to select a first resistance setting or level and therefore press the input area 31 containing the number "1". The sensor 48 aligned with the number "1" (see...) Figure 11 The sensor 48 senses the strain force generated when the user engages the corresponding input area 31 (step 602). The sensor 48 then transmits a signal or data corresponding to the sensed strain force (e.g., force in grams) and / or the sensed duration (e.g., the length of time the sensor senses the strain force value) to the control system 100. Note that in other examples, the control system 100 includes a timer, such that the control system 100 is configured to determine the sensed duration based on the signal from the sensor 48. In step 603, the control system 100 receives the signal or data and compares the sensed strain force and / or the sensed duration to a predetermined threshold force (e.g., 300.0 grams of force) and / or a predetermined threshold duration (e.g., 200.0 milliseconds), respectively. The predetermined threshold force and / or predetermined threshold duration may be stored in the memory system 104, for example, in a lookup table. If, in step 604, the control system 100 determines that the sensed strain force is greater than a threshold force and the sensed duration is equal to or greater than a threshold duration, then the control system 100 further determines that the strain force sensed by sensor 48 is a result of the user pressing the input area 31 of the number "1". Therefore, in step 605, the control system 100 controls the LEDs to emit light illuminating the number "1" and controls and / or commands the resistance device 90 to apply a first resistance level.

[0063] In some examples, if the control system 100 determines that the user presses another input area 31 (e.g., the input area 31 corresponding to the number "2"), the control system 100 will turn off the light source 49 corresponding to the other input area 31, turn on the light source 49 corresponding to the pressed input area 31, and further change the resistance device 90 to apply the resistance setting corresponding to the pressed input area 31.

[0064] In some examples, the control system 100 determines that the sensed duration is less than a threshold duration, that the input area 31 was not pressed correctly (e.g., the input area 31 was pressed too quickly or for insufficient duration, or the input area 31 was accidentally "brushed" by the user's arm), and therefore ignores the signal from the sensor 48 and takes no action. In some examples, if the sensed duration of the user pressing the input area 31 is within a predetermined time range (e.g., 3.0-5.0 seconds), the control system 100 determines that the user has pressed the input area 31 to enter the programming mode of the control system 100, which allows the user to adjust the function of (one or more) input areas 31. For example, the user can press the input area 31 corresponding to the number "3" for 3.0 or 4.0 seconds to enter the programming mode and further set the resistance setting associated with the input area 31 corresponding to the number "3" to the current resistance setting or the maximum resistance setting or level. The programming mode can also allow the user to change the brightness or color of the light emitted by the light source 49, the intensity of the light emitted by the light source 49, and / or other functions of the exercise machine 10.

[0065] In some examples, if the control system 100 determines that the sensed strain force is less than a threshold force, the control system 100 will determine that the user did not press input area 31, and that the sensed strain force is the result of another object unintentionally pressing the input area (e.g., a sweat drop) or the strain force sensed by sensor 48 when the user presses another (one or more) input areas 31 (e.g., more than one sensor 48 can sense the strain force in PCBA 52 that may be caused by pressing one of the input areas 31). Therefore, the memory system 104 includes algorithms that help analyze the strain forces sensed from multiple sensors 48, allowing the control system 100 to ignore certain signals and / or determine which input area 31 the user actually pressed. For example, if the user presses the input area 31 for the number "2", the sensor 48 directly below the input area 31 for the number "2" will sense a higher strain force (e.g., 400.0 grams) than the sensors 48 below other input areas 31 (e.g., sensor 48 senses 250.00 grams). In this example, the control system 100 will determine that the input area 31 of the number "2" is pressed and ignore the signals from other sensors 48 because the strain force value sensed by the sensor 48 below the input area 31 of the number "2" is greater than the threshold force, and the strain force sensed by other sensors 48 is less than the strain force value sensed by the sensor 48 below the input area 31 of the number "2".

[0066] In another example, if a user presses between input area 31 for the number "2" and input area 31 for the number "3", both sensors 48 below these input areas 31 can sense similar strain. In this example, the control system 100 will determine that a single input area 31 is not being pressed properly, and therefore, since the sensed strain values ​​are not sufficiently separated from each other, the control system 100 will ignore the signal and take no action.

[0067] Figures 22-23 This is a schematic diagram of an example control system 100 of this disclosure. In these examples, the input module 30 includes a separate control system 200, which is connected to the exercise machine 10 ( Figure 4 The control system 100, sensor 48, and light source 49 communicate with each other. Note that the control system 200 may be similar to the control system 100 described above and includes similar components and / or features. The control system 200 may include a microprocessor.

[0068] Figure 22 It depicts three corresponding input regions 31 (see, for example) Figures 5-6 The system includes an input module 30 for three sensors 48 and three light sources 49. Sensors 48 communicate with the control system 200 via a communication link 101. The control system 200 may include a microprocessor (µP). In some examples, sensors 48 provide analog input signals to the control system 200.

[0069] Several communication links 101 extend from control system 200 to various components of exercise machine 10. For example, control system 100, control system 200, and / or display interface 19 communicate via one or more communication links 101. Control system 100 may be configured to provide interrupt signals to various components of exercise machine 10 based on input signals received by control system 200. For example, events leading to an interrupt signal include a user pressing an input area 31, sensor 48 sensing a user pressing an input area 31, an INT flag being placed on control system 100, and / or control system 100 receiving a data packet (e.g., data input by the user via display interface 19). Control system 200 may be configured to operate in the background during operation of exercise machine 10 and communicate with control system 100 only when necessary. Control system 200 may activate light source 49 (see [link to relevant documentation]) based on input received from the user via display interface 19. Figure 6The brightness of the light source 49 can be adjusted. When the display interface 19 is "frozen" or "locked," the control system 100 can also enable a "reset" of the input module 30 and / or the processing system of the control system 100. The control system 200 is also allowed to selectively turn the light source 49 on or off based on inputs received in the control system 200 and / or the control system 100. The input module 30 includes a voltage regulator 204 that converts the input voltage to an appropriate voltage.
