Description

[0001] SYSTEM FOR POSITIONING A SENSOR WITHIN A DISPENSER

[0002] BACKGROUND

[0003] Absorbent products are widely used to absorb liquids and clean surfaces. For example, absorbent products, such as paper towels, wipes, toilet paper, etc., are frequently provided in restrooms, kitchens, and other services areas to absorb liquids and / or clean surfaces. Such absorbent products are frequently provided within dispensers to protect the absorbent products and facilitate dispensing of the absorbent products by users.

[0004] In many service areas, such as office buildings, health care facilities, manufacturing plants, etc., attendants service the dispensers on a scheduled or periodic basis to ensure that the service area is stocked with absorbent products. The attendants frequently service numerous areas within a building. In general, the attendants have little to no knowledge of the current condition of the dispensers, including the fullness state of the dispensers, until the attendants visually inspect the dispensers. Depending upon the interval between service checks, the absorbent products in dispensers may be completely depleted. Thus, the dispensers may be empty for a significant period before the attendant checks and refills the dispensers.

[0005] Sensors can assist with remotely monitoring absorbent products remaining in a dispenser but pose challenges. For instance, a wide variety of dispenser makes and models are in use. Retrofitting such dispensers with sensors for monitoring absorbent products within the dispensers is challenging. Moreover, correctly positioning sensors within the wide variety of dispenser makes and models is difficult due to the differing installation space available within each dispenser make and model. If placed incorrectly, the sensors may not function correctly and may improperly read absorbent product levels within the dispensers.

[0006] Systems and methods for facilitating intuitive placement of sensors within dispensers would be useful.

[0007] SUMMARY

[0008] In general, the present disclosure is directed to systems and methods for installing sensors within dispensers in order to detect absorbent product within the dispensers. The systems and methods may utilize one or more positioning feature(s) keyed to engage with specific features of the dispenser in order to properly position the sensor within the dispenser. For instance, the positioning feature(s) may engage with the features of the dispenser to position and orient the sensor towards absorbent product within the dispenser. If an installer attempts to engage the positioning feature(s) with portions of the dispenser other that the correct feature(s) of the dispenser, the installer can recognize the mismatch between the positioning feature(s) and the incorrect feature(s) of the dispenser and adjust the sensor to the correct location. Thus, the systems and methods of the present disclose may advantageously provide intuitive feedback regarding the correct placement of sensors within dispensers.

[0009] In one example embodiment, a sensor positioning system includes a sensor. A sensor mounting bracket is mountable within a dispenser.

[0025] DETAILED DESCRIPTION

[0026] The present disclosure is generally directed to a sensor positioning system. The system may include a sensor and a mounting bracket. The mounting bracket may be installed within a dispenser and thereby provide a mounting location for the sensor within the dispenser. For example, the sensor may be positioned on a surface of the mounting bracket. The system may also include a spacer. The spacer may be configured to engage with features of the dispenser to assist with proper positioning of the mounting bracket in the dispenser. For example, the spacer may include one or both of a first positioning feature and a second positioning feature. The first positioning feature may be engageable with a first feature of the dispenser, and the second positioning feature may be engageable with a second feature of the dispenser. Thus, e.g., the spacer may be keyed to one, two, or more features of the dispenser. If an installer attempts to engage the first and second positioning features in an incorrect position (e.g., not with the first and second features of the dispenser), the installer can recognize the mismatch between spacer and the dispenser and move the spacer to the correct location, e.g., such that the first and second positioning features engage with the first and second features of the dispenser.

[0027] When each of the positioning features of the spacer engage with the respective feature of the dispenser, the spacer may provide a mounting location for the mounting bracket in the dispenser. For instance, the spacer may include a first engagement feature and a second engagement feature. The mounting bracket may also include a first engagement feature and a second engagement feature. The first engagement feature of the spacer may be shaped complementary to the first engagement feature of the mounting bracket, and the second engagement feature of the spacer may be shaped complementary to the second engagement feature of the mounting bracket. Thus, the engagement features of the mounting bracket may be keyed for engagement with the engagement features of the spacer. When each of the engagement features of the mounting bracket engages with the respective engagement feature of the spacer (and the spacer is installed at the correct location in the dispenser), the mounting bracket may be disposed at a correct location within the dispenser. The mounting bracket may be mounted to the dispenser at the correct location using the spacer as a positioning guide. Thus, the spacer may engage features of the dispenser to provide the mounting location for the mounting bracket in the dispenser. With the mounting bracket mounted within the dispenser, the sensor may be installed on the mounting bracket at a correct location for the sensor to detect absorbent products within the dispenser.

[0028] In example embodiments, a sensor positioning system may include a plurality of sensors, a plurality of sensor mounting brackets, and a plurality of spacers. The mounting brackets may be mounted within a dispenser. Each of the sensors may be positioned on a surface of a respective mounting bracket. The spacers may engage features of the dispenser to provide positioning guides for mounting of the mounting brackets in the dispenser. For example, engagement features of the spacers may be shaped complementary to respective features of the dispenser. Thus, the spacers may be keyed to specific locations within the dispenser. When the spacers are mounted at the specific locations, engagement features of the mounting brackets may engage with engagement features of the spacers to locate the correct mounting bracket at each of the specific locations in the dispenser. Thus, the installer may utilize the spacers to correctly position two, three, four, five or more sensors within the dispenser.

[0029] In example embodiments, the locating features of the spacer may be integrated into the mounting bracket(s). Thus, locating features on the mounting bracket(s) may engage with corresponding features of the dispenser to correctly locate the mounting bracket(s) within the dispenser.

[0030] Additional aspects of such sensor positioning systems are described in more detail below.

[0035] Dispenser:

[0036] FIGS. 1 and 2 show a dispenser 100 according to an example embodiment of the present subject matter. The dispenser 100 may be configured for dispensing an absorbent product, such as a paper towel, a bath tissue, or a wiper. The absorbent products (e.g., sheets or rolls of material) may be utilized to absorb liquids and / or clean surfaces. As discussed in greater detail below, the dispenser 100 may include features for detecting the amount or quantity of absorbent product remaining within the dispenser 100. Moreover, example aspects of the present subject matter may advantageously assist with positioning and mounting sensors within the dispenser 100 for accurate sensing of the absorbent product.

[0037] As shown in FIGS. 1 and 2, the dispenser 100 may include a housing 101 with a base frame 110 and a front cover 112. Thus, in example embodiments, the housing 101 may have a two-part configuration. The base frame 110 may be secured to a wall or other structural element. For instance, a rear wall 111 of the base frame 110 may be fastened to a wall within a restroom. The front cover 112 may be mounted to the base frame 110 in order to enclose an interior 113 of the dispenser 100. For example, the interior 113 of the dispenser 100 may be defined between the base frame 110 and the front cover 112. In example embodiments, the front cover 112 may be rotatably mounted to the base frame 110 via a hinge. Thus, as shown in FIGS. 1 and 2, the front cover 112 may be rotatable between a closed position (FIG. 1) and an open position (FIG. 2). In the closed position, the front cover 112 may enclose and limit access to the interior 113 of the dispenser 100. Conversely, the front cover 112 may be rotated to open and allow access to the interior 113 of the dispenser 100. A lock 115 may selectively secure the front cover 112 on the base frame 110. In other example embodiments, the front cover 112 may be completely separable from the base frame 110.

[0038] As shown in FIG. 1, the housing 101 may extend between a top portion 102 and a bottom portion 104 along a vertical direction V. The housing 101 may also extend between a rear portion 106 and a front portion 108 along a transverse direction T, which is oriented perpendicular to the vertical direction V. A panel 114 may be removably mounted to the front cover 112, e.g., at the front portion 108 of the housing 101 . The panel 114 may be selected for cosmetic appeal. For instance, the panel 114 may be selected with a desired surface ornamentation and / or color.

[0039] Turning now to FIG. 2, the dispenser 100 may also include absorbent material roll holders 120. The roll holders 120 may be mounted within the housing 101 on the base frame 110, e.g., such that the roll holders 120 extend from the base frame 110 into the interior 113 of the dispenser 100. The roll holders 120 may configured for supporting a roll of sheet material, such as paper towels, within the interior 113 of the dispenser 100. Each of the roll holders 120 may include a bearing 122. The roll of sheet material may be mounted on the bearings 122 such that the roll of sheet material is rotatable relative to the housing 101 within the interior 113 of the dispenser 100.

[0040] The dispenser 100 may also include an automatic dispensing assembly 130. The automatic dispensing assembly 130 may include a drive roller rotatable by a drive motor to dispense absorbent material. For instance, a free end of a roll of sheet material on the roll holders 120 may be inserted into the automatic dispensing assembly 130, and the automatic dispensing assembly 130 may be configured for dispensing the free end of the roll of sheet material through an opening 116 at an exterior of the housing 101. The automatic dispensing assembly 130 may include a sensor for detecting a user indication for absorbent material. For instance, the sensor may detect a hand of the user waving below the opening 116, and the automatic dispensing assembly 130 may activate the drive motor to dispense the free end of a roll of sheet material through the opening 116. Thus, the automatic dispensing assembly 130 may be configured for selectively dispensing absorbent material from the interior 113 of the dispenser 100 based on inputs from the sensor of the automatic dispensing assembly 130. The automatic dispensing assembly 130 may be powered by batteries contained in a battery compartment or may be powered by an AC distribution system.

[0041] It will be understood that the dispenser 100 is provided by way of example only. The present subject matter may be used in or with other suitable dispensers in alternative example embodiments. For example, FIGS. 3 and 4 show a dispenser 200 according to another example embodiment of the present subject matter. The dispenser 200 may also be configured for dispensing an absorbent product, such as a paper towel, a bath tissue, or a wiper. As discussed in greater detail below, the dispenser 200 may include features for detecting the amount or quantity of absorbent product remaining within the dispenser 200. Moreover, example aspects of the present subject matter may advantageously assist with positioning and mounting sensors within the dispenser 200 for accurate sensing of the absorbent product.

[0042] As shown in FIGS. 3 and 4, the dispenser 200 may include a housing 201 with a base frame 210 and a front cover 212. The base frame 210 may be secured to a wall or other structural element, and the front cover 212 may be mounted to the base frame 210 in order to enclose an interior 213 of the dispenser 200. In example embodiments, the front cover 212 may be rotatably mounted to the base frame 210 via a hinge. Thus, as shown in FIGS. 3 and 4, the front cover 212 may be rotatable between a closed position (FIG. 3) and an open position (FIG. 4). In the closed position, the front cover 212 may enclose and limit access to the interior 213 of the dispenser 200. Conversely, the front cover 212 may be rotated to open and allow access to the interior 213 of the dispenser 200. A lock 215 may selectively secure the front cover 212 on the base frame 210. In other example embodiments, the front cover 212 may be completely separable from the base frame 210.

[0043] As shown in FIG. 3, the housing 201 may extend between a top portion 202 and a bottom portion 204 along a vertical direction V. The housing 201 may also extend between a rear portion 206 and a front portion 208 along a transverse direction T, which is oriented perpendicular to the vertical direction V. A panel 214 may be removably mounted to the front cover 212, e.g., at the front portion 208 of the housing 201. The panel 214 may be selected for cosmetic appeal. For instance, the panel 214 may be selected with a desired surface ornamentation and / or color. In example embodiments, the panels 114, 214 of various dispensers may be matched within a room, building, etc.

[0044] Turning now to FIG. 4, the dispenser 200 may also include absorbent material roll holders 220. The roll holders 220 may be mounted within the housing 201 on the base frame 210, e.g., such that the roll holders 220 extend from the base frame 210 into the interior 213 of the dispenser 200. The roll holders 220 may configured for supporting a roll of sheet material, such as toilet paper, within the interior 213 of the dispenser 200. Each of the roll holders 220 may include a bearing 222. The roll of sheet material may be mounted on the bearings 222 such that the roll of sheet material is rotatable relative to the housing 201 within the interior 213 of the dispenser 200. The dispenser 200 may be configured for manual dispensing in the example embodiment shown in FIGS. 3 and 4.

[0045] Sensing System:

[0046] FIG. 5 shows an absorbent product sensing system 300 according to an example embodiment of the present subject matter. The sensing system 300 may be utilized in or with a suitable dispenser to detect the amount or quantity of absorbent product remaining within the dispenser. As an example, the sensing system 300 may be used in or with the dispenser 100 (FIGS. 1 and 2) and / or the dispenser 200 (FIGS. 3 and 4). However, it will be understood that sensing system 300 may be used in or with different dispensers in other example embodiments.

[0047] As shown in FIG. 5, the sensing system 300 includes a plurality of sensors 330 and a plurality of sensor mounting brackets 340. Each of the sensors 330 may be mounted on a respective one of the mounting brackets 340. The mounting brackets 340 may be mounted within a dispenser at a respective location, e.g., such that the sensors 330 on the mounting brackets 340 are positioned and oriented for detecting the amount or quantity of absorbent material, such as a roll of paper towels and / or a roll of toilet paper, within the associated dispenser. For instance, the mounting brackets 340 may be mounted on a panel 310 of the dispenser at a respective location. Moreover, each of the sensors 330 may be positioned and oriented on the mounting brackets 340 such that each of the sensors 330 is directed towards a respective rotational axis X of roll holders 320. As discussed in greater detail below, the present subject matter may utilize various features of the dispenser to assist with proper positioning and orientation of the sensors 330 in the dispenser.

[0048] Sensor Installation:

[0049] FIGS. 6 through 13 show installation of a sensor 330 and mounting bracket 340 on the panel 310. With reference to FIG. 6, a spacer 350 may be configured to assist with proper positioning of the mounting bracket 340 on the panel 310, e.g., such that the sensor 330 is positioned and oriented towards the absorbent material within the dispenser. The spacer 350 may include a first positioning feature 362 and a second positioning feature 364. The first and second positioning features 362, 364 may be configured for engaging with corresponding features on the associated dispenser to assist with proper positioning and orientation of the sensor 330 and mounting bracket 340 in the dispenser. For example, the dispenser may include a first feature 312 and a second feature 314. The first feature 312 may correspond to a portion of the roll holder 320 (FIG. 5) in some example embodiments. The second feature 314 may correspond to a portion of the support bracket 322 for the roll holder 320 (FIG. 5) in some example embodiments. The spacer 350 may be configured such that the first positioning feature 362 is engageable with the first feature 312 of the dispenser and the second positioning feature 364 is engageable with the second feature 314. Thus, the spacer 350 may position the mounting bracket 340 within the dispenser such that the sensor 330 is positioned and oriented for detecting the absorbent material within the dispenser when the sensor 330 is positioned on a surface 346 of the mounting bracket 340.

[0050] The first and second positioning features 362, 364 may be spaced apart on the spacer 350. As an example, with refence to FIG. 7, the first and second positioning features 362, 364 may be spaced apart along a vertical direction V and / or a lateral direction L, which is perpendicular to the vertical direction V. Moreover, the spacer 350 may extend between a first end portion 351 and a second end portion 353 along the lateral direction L. The first positioning feature 362 may be positioned at or adjacent the first end portion 351 of the spacer 350, and the second positioning feature 364 may be positioned at or adjacent the second end portion 353 of the spacer 350. Thus, the first and second positioning features 362, 364 of the spacer 350 may be positioned opposite each other on the spacer

[0051] 350 in example embodiments.

[0052] In example embodiments, the first and second positioning features 362, 364 may have different shapes. For example, the first positioning feature 362 may be shaped incompatibility with the second feature 314 of the dispenser. Similarly, the second positioning feature 364 may be shaped incompatibility with the first feature 312 of the dispenser. Thus, the first and second positioning features 362, 364 may be keyed to the first and second features 312, 314 of the dispenser, respectively, such that the spacer 350 may engage with the features of the dispenser in one specific arrangement of the spacer 350 relative to the features of the dispenser.

[0053] As shown in FIG. 7, the first positioning feature 362 may include a first edge 366 and a second edge 367 of the spacer 350. The first edge 366 may extend along the lateral direction L, and the second edge 367 may extend along the vertical direction V and / or face towards the first end portion

[0054] 351 of the spacer 350. Thus, the first and second edges 366, 367 of the first positioning feature 362 may be oriented perpendicular to each other in example embodiments. The spacer 350 may be shaped such that the first positioning feature 362 is open facing opposite the first and second edges 366, 367. The second positioning feature 364 may include a third edge 368 and a fourth edge 369 of the spacer 350. The third edge 368 may extend along the lateral direction L, and the fourth edge 369 may extend along the vertical direction V and / or may face towards the second end portion 353 of the spacer 350. Thus, the third and fourth edges 368, 369 of the second positioning feature 364 may be oriented perpendicular to each other in example embodiments. The spacer 350 may be shaped such that the second positioning feature 364 is open facing opposite the third and fourth edges 368, 369. The first edge 366 may be spaced apart from the third edge 368 along the vertical direction V and / or the lateral direction L, e.g., when the spacer 350 is engaged with the first and second features 312, 314. The first edge 366 may also be oriented parallel to the third edge 368 in example embodiments. The second edge 367 may be spaced apart from the fourth edge 369 along the vertical direction V and / or the lateral direction L, e.g., when the spacer 350 is engaged with the first and second features 312, 314. The second edge 367 may also be oriented parallel to the fourth edge 369 in example embodiments. As may be seen from the above, the first and second positioning features 362, 364 may correspond to open sockets shaped complementary to the first and second features 312, 314, respectively.

[0055] The shape and / or positioning of the first and second positioning features 362, 364 may assist with holding the spacer 350 in the dispenser. For instance, when an installer engages the spacer 350 with the first and second features 312, 314, the spacer 350 may be coupled to the dispenser such that the spacer 350 is limited or prevented from rotating relative to the dispenser. For instance, the spacer 350 may be removable from the dispenser by translating the spacer 350 upwardly from the first and second features 312, 314 (e.g., along the vertical direction V) and / or outwardly from the first and second features 312, 314 (e.g., along the lateral direction L). Thus, the spacer 350 may rest on the first and second features 312, 314, e.g., without requiring the installer to hold the spacer 350 against the dispenser. For instance, the spacer 350 may remain on the first and second features 312, 314 in a hands-free manner while the installer continues installing the mounting bracket 340 on the dispenser.

[0056] With reference to FIGS. 6 and 7, the installer may first position the spacer 350 such that the first positioning feature 362 engages with the first feature 312 of the dispenser and the second positioning feature 364 engages with the second feature 314. Moreover, the first and second edges 366, 367 of the first positioning feature 362 may be disposed against the first feature 312 of the dispenser, and the third and fourth edges 368, 369 of the second positioning feature 364 may be disposed against the second feature 314 of the dispenser. With the spacer 350 engaged with the dispenser, the spacer 350 may be positioned for guiding installation of the mounting bracket 340.

[0057] As shown in FIG. 7, the spacer 350 may include a first engagement feature 352 and a second engagement feature 354. The first and second engagement feature 352, 354 may be configured for engaging with corresponding features on the mounting bracket 340 to assist with proper positioning and orientation of the sensor 330 and mounting bracket 340 in the dispenser. For example, the mounting bracket 340 may include a first engagement feature 352 and a second engagement feature 354. The first engagement feature 352 of the spacer 350 may be shaped complementary to the first engagement feature 342 of the mounting bracket 340, and the second engagement feature 354 of the spacer 350 may be shaped complementary to the second engagement feature 344 of the mounting bracket 340. Thus, e.g. , the first and second engagement feature 352, 354 of the spacer 350 may be keyed to the first and second engagement features 342, 344 of the mounting bracket 340, respectively. Moreover, the first engagement feature 352 of the spacer 350 may engage with the first engagement feature 342 of the mounting bracket 340 and the second engagement feature 354 of the spacer 350 may engage with the second engagement feature 344 of the mounting bracket 340 in one specific orientation, which corresponds to the proper position and orientation for the sensor 330 in the dispenser, e.g., towards the rotational axis X of roll holders 320.

[0058] The first engagement feature 352 of the spacer 350 and the first engagement feature 342 of the mounting bracket 340 may include a respective projection and recess. For instance, the first engagement feature 352 of the spacer 350 may correspond to a recess, and the first engagement feature 342 of the mounting bracket 340 may correspond to a projection, which is sized and positioned for receipt within the first engagement feature 352 of the spacer 350. Similarly, the second engagement feature 354 of the spacer 350 and the second engagement feature 344 of the mounting bracket 340 may also include a respective projection and recess. The second engagement feature 354 of the spacer 350 may correspond to a pair of projections with an intermediate space therebetween, and the second engagement feature 344 of the mounting bracket 340 may also correspond to a pair of projections with an intermediate space therebetween, which are sized and positioned for receipt with the second engagement feature 354 of the spacer 350. It will be understood that the sizing, number, and arrangement of the projections and recesses for the first and second engagement features 342, 344 of the mounting bracket 340 and the first and second engagement features 352, 354 of the spacer 350 is provided by way of example and that other arrangements may be used in further example embodiments.

[0059] The first and second engagement features 352, 354 of the spacer 350 may be spaced apart on the spacer 350. As an example, with refence to FIG. 6, the first and second engagement features 352, 354 of the spacer 350 may be spaced apart along the lateral direction L. The first engagement feature 352 may be positioned at or adjacent the first end portion 351 of the spacer 350, and the second engagement feature 354 may be positioned at or adjacent the second end portion 353 of the spacer 350. Thus, the first and second engagement features 352, 354 of the spacer 350 may be positioned opposite each other on the spacer 350 in example embodiments.

[0060] In example embodiments, the first and second engagement features 352, 354 of the spacer 350 may have different shapes. For example, the first engagement feature 352 may be shaped incompatibility with the second engagement feature 344 of the mounting bracket 340. Similarly, the second positioning feature 354 of the spacer 350 may be shaped incompatibility with the first engagement feature 342 of the mounting bracket 340. Thus, the first and second engagement feature 352, 354 of the spacer 350 may be keyed to the first and second engagement features 342, 344 of the mounting bracket 340, respectively, such that the mounting bracket 340 may engage with the spacer 350 in one specific arrangement of the mounting bracket 340 relative to the spacer 350.

[0061] The first and second engagement features 342, 344 of the mounting bracket 340 may be spaced apart on the mounting bracket 340. As an example, with refence to FIG. 8, the first and second engagement features 342, 344 of the mounting bracket 340 may be spaced apart along the lateral direction L. The first engagement feature 342 may be positioned at or adjacent the first end portion 341 of the mounting bracket 340, and the second engagement feature 344 may be positioned at or adjacent the second end portion 343 of the mounting bracket 340. Thus, the first and second engagement features 342, 344 of the mounting bracket 340 may be positioned opposite each other on the mounting bracket 340 in example embodiments.

[0062] With reference to FIGS. 8 through 10, the installer may remove a film from an adhesive tape 348 (or prepare another fastening mechanism for the mounting bracket 340, such as glue, screws, etc.) on the mounting bracket 340. The installer may then align the first engagement feature 342 of the mounting bracket 340 with the first engagement feature 352 of the spacer 350 and also align the second engagement feature 344 of the mounting bracket 340 with the second engagement feature 354 of the spacer 350. With the mounting bracket 340 properly positioned with the spacer 350, the mounting bracket 340 may be disposed in the dispenser in the proper position and orientation for the sensor 330, e.g . , towards the rotational axis X of roll holders 320.

[0063] In example embodiments, the first and second engagement feature 352, 354 of the spacer 350 may be positioned at a top portion of the spacer 350, e.g., such that the projections of the first and second engagement feature 352, 354 of the spacer 350 extend upwardly along the vertical direction V from the spacer 350. The first and second engagement features 342, 344 of the mounting bracket 340 may be positioned at a bottom portion of the mounting bracket 340, e.g., such that the projections of the first and second engagement features 342, 344 of the mounting bracket 340 extend downwardly along the vertical direction V from the mounting bracket 340. Thus, e.g., the mounting bracket 340 may rest on the spacer 350 when the spacer 350 engages the dispenser as shown in FIG. 10. The installer may then secure the mounting bracket 340 on the panel 310, e.g., by pressing the adhesive tape 348 onto the panel 310 or using another suitable fastener. As shown in FIG. 11 , the installer may remove the spacer 350 after the mounting bracket 340 is secured on the panel 310. In example embodiments, the mounting bracket 340 may be colored or formed to match the sensor 330 and / or dispenser. For instance, the mounting bracket 340 may be a grey, e.g., when the sensor 330 and / or dispenser is formed with white, grey, or metallic material. Conversely, the spacer 350 may have a different color than the mounting bracket 340. For example, the spacer 350 may be colored or formed to mismatch the sensor 330 and / or the dispenser. For instance, the spacer 350 may be a red, blue, purple, orange, yellow, etc., e.g., when the sensor 330 and / or the dispenser is formed with white, grey, or metallic material. Such coloring may highlight the removability of the spacer 350 from the sensor 330 and / or the dispenser and the integration of the mounting bracket 340 in the dispenser, which can assist the installer with identifying the process for installing the sensors 330 in the dispenser.

[0064] As shown in FIG. 12, the sensor 330 (e.g., a housing 335 of the sensor 330) may include a first engagement feature 332 and a second engagement feature 334. The first and second engagement feature 332, 334 may be configured for engaging with corresponding features on the mounting bracket 340 to assist with proper positioning and orientation of the sensor 330 in the dispenser. For example, the mounting bracket 340 may include a third engagement feature 372 and a fourth engagement feature 374. The first engagement feature 332 of the sensor 330 may be shaped complementary to the third engagement feature 372 of the mounting bracket 340, and the second engagement feature 334 of the sensor 330 may be shaped complementary to the fourth engagement feature 374 of the mounting bracket 340. Thus, e.g., the first and second engagement feature 332, 334 of the sensor 330 may be keyed to the third and fourth engagement features 372, 374 of the mounting bracket 340, respectively. Moreover, the first engagement feature 332 of the sensor 330 may engage with the third engagement feature 372 of the mounting bracket 340 and the second engagement feature 334 of the sensor 330 may engage with the fourth engagement feature 374 of the mounting bracket 340 in one specific orientation, which corresponds to the proper position and orientation for the sensor 330 on the mounting bracket 340, e.g., towards the rotational axis X of roll holders 320.

[0065] The first engagement feature 332 of the sensor 330 and the third engagement feature 372 of the mounting bracket 340 may include a respective projection and recess. For instance, the first engagement feature 332 of the sensor 330 may correspond to a recess, and the third engagement feature 372 of the mounting bracket 340 may correspond to a projection, which is sized and positioned for receipt within the first engagement feature 332 of the sensor 330. Similarly, the second engagement feature 334 of the sensor 330 and the fourth engagement feature 374 of the mounting bracket 340 may also include a respective projection and recess. The second engagement feature 334 of the sensor 330 may correspond to a projection, and the second engagement feature 334 of the sensor 330 may also correspond to a projection, which has a different size and / or shape than the first engagement feature 332 of the sensor 330. It will be understood that the sizing, number, and arrangement of the projections and recesses for the first and second engagement features 332, 334 of the sensor 330 and the third and fourth engagement features 372, 374 of the mounting bracket 340 is provided by way of example and that other arrangements may be used in further example embodiments.

[0066] In example embodiments, the first and second engagement features 332, 334 of the sensor 330 may have different shapes. For example, the first engagement feature 332 of the sensor 330 may be shaped incompatibility with the fourth engagement feature 374 of the mounting bracket 340. Similarly, the second positioning feature 334 of the sensor 330 may be shaped incompatibility with the third engagement feature 372 of the mounting bracket 340. Thus, the first and second engagement feature 332, 334 of the sensor 330 may be keyed to the third and fourth engagement features 372, 374 of the mounting bracket 340, respectively, such that the sensor 330 may engage with the mounting bracket 340 in one specific arrangement of the sensor 330 relative to the mounting bracket 340.

[0067] The first and second engagement features 332, 334 of the sensor 330 may be spaced apart on the sensor 330. As an example, with refence to FIG. 12, the first and second engagement features 332, 334 of the sensor 330 may be spaced apart along the lateral direction L. Moreover, the sensor 330 may extend between a first end portion 331 and a second end portion 333 along the lateral direction L. The first engagement feature 332 may be positioned at or adjacent the first end portion 331 of the sensor 330, and the second engagement feature 334 may be positioned at or adjacent the second end portion 333 of the sensor 330. Thus, the first and second engagement features 332, 334 of the sensor 330 may be positioned opposite each other on the sensor 330 in example embodiments.

[0068] The third and fourth engagement features 372, 374 of the mounting bracket 340 may be spaced apart on the mounting bracket 340. As an example, with refence to FIG. 13, the third and fourth engagement features 372, 374 of the mounting bracket 340 may be spaced apart along the lateral direction L. The third engagement feature 372 may be positioned at or adjacent the first end portion 341 of the mounting bracket 340, and the fourth engagement feature 374 may be positioned at or adjacent the second end portion 343 of the mounting bracket 340. Thus, the third and fourth engagement features 372, 374 of the mounting bracket 340 may be positioned opposite each other on the mounting bracket 340 in example embodiments.

[0069] With reference to FIGS. 12 through 16, the installer may remove a film from an adhesive tape 338 (or prepare another fastening mechanism for the sensor 330, such as glue, screws, etc.) on the sensor 330. The installer may then align the first engagement feature 332 of the sensor 330 with the third engagement feature 372 of the mounting bracket 340and also align the second engagement feature 334 of the sensor 330 with the fourth engagement feature 374 of the mounting bracket 340. With the sensor 330 properly positioned with the mounting bracket 340, the sensor 330 may be disposed in the dispenser in the proper position and orientation for the sensor 330, e.g . , towards the rotational axis X of roll holders 320.

[0070] In example embodiments, the mounting bracket 340 may include a surface 346 for the sensor 330. The surface 346 may be planar and / or shaped complementary to the sensor 330. The surface 346 may be oriented such that a tangent line from the surface 346 may be oriented at an angle with respect to the vertical direction V. The angle between the tangent line from the surface 346 and the vertical direction V may be no less than fifteen degrees (15°) and no greater than seventy-five degrees (75°) in example embodiments, such as about forty-five degrees (45°). A sensor aperture 339 may be oriented in the same or similar manner with respect to the vertical direction V.

[0071] Positioning System:

[0072] Turning now to FIGS. 17 though 20, the system 300 may include a plurality of mounting brackets 340, 440 and a plurality of spacers 350, 450. Each of the mounting brackets 340, 440 may be configured for placement at a respective location within a dispenser. The spacers 350, 450 may be configured for engaging respective positioning features of the dispenser to properly position the mounting brackets 340, 440 within the dispenser. The engagement feature 342, 344, 442, 444 of the mounting bracket 340, 440 may be keyed to the engagement feature 352, 354, 452, 454 of the spacers 350, 450 such that the spacers 350, 450 position the mounting bracket 340, 440 at the correct locations within the dispenser. As shown in FIGS. 21 and 22, the engagement feature 342, 344 of the mounting bracket 340 may not match or be engageable with the engagement feature 452, 454 of the spacers 450, and the engagement feature 442, 444 of the mounting bracket 440 may not match or be engageable with the engagement feature 352, 354 of the spacers 350. Thus, the mounting bracket 340 may not be keyed to the spacers 450, and the mounting bracket 440 may not be keyed to the spacers 350.

[0073] Mounting Brackets:

[0074] It will be understood that the positioning features of the spacer may be incorporated in or integral with the mounting bracket in certain example embodiments. The aspects of the positioning features of the spacer described above for the example embodiments shown in FIGS. 5 through 22 may be utilized with the example embodiments described below, in which the positioning features are incorporated in or integral with the mounting bracket. Reference is made to the description above and not repeated below for the sake of brevity.

[0075] FIG. 23 shows a mounting bracket 540 according to another example embodiment of the present subject matter. In FIG. 23, the mounting bracket 540 may be configured to assist with proper positioning on a panel, e.g ., such that the associated sensor is positioned and oriented towards the absorbent material within the dispenser. The mounting bracket 540 may include a first positioning feature 542 and a second positioning feature 544. The first and second positioning features 542, 544 may be configured for engaging with corresponding features on the associated dispenser to assist with proper positioning and orientation of the sensor and mounting bracket 540 in the dispenser. For example, the dispenser may include a first feature 512 and a second feature 514. The first feature 512 may correspond to a corner wall in some example embodiments. The second feature 514 may correspond to another, separate corner wall in some example embodiments. The mounting bracket 540 may be configured such that the first positioning feature 542 is engageable with the first feature 512 of the dispenser and the second positioning feature 544 is engageable with the second feature 514. Thus, the mounting bracket 540 may thus be positioned within the dispenser such that the sensor is positioned and oriented for detecting the absorbent material within the dispenser when the sensor is positioned on a surface 546 of the mounting bracket 540. The first and second positioning features 542, 544 may be spaced apart on the mounting bracket 540. For example, the first and second positioning features 542, 544 of the mounting bracket 540 may be positioned opposite each other on the mounting bracket 540 in example embodiments.

[0076] The shape and / or positioning of the first and second positioning features 542, 544 may assist with holding the mounting bracket 540 in the dispenser. For instance, when an installer engages the mounting bracket 540 with the first and second features 512, 514, the mounting bracket 540 may be coupled to the dispenser such that the mounting bracket 540 is limited from moving relative to the dispenser.

[0077] FIG. 24 shows a mounting bracket 640 according to another example embodiment of the present subject matter In FIG. 24, the mounting bracket 640 may be configured to assist with proper positioning on a panel, e.g., such that the associated sensor is positioned and oriented towards the absorbent material within the dispenser. The mounting bracket 640 includes similar components as the mounting bracket 540 described above. Thus, repetitive description is omitted for the sake of brevity. However, in the example embodiment shown in FIG. 24, the first feature 612 corresponds to a rib, and the second feature 614 corresponds to another, separate rib. The mounting bracket 640 may be configured such that the first positioning feature 642 is engageable with the first feature 612 of the dispenser and the second positioning feature 644 is engageable with the second feature 614.

[0078] FIG. 25 shows a mounting bracket 740 according to another example embodiment of the present subject matter. In FIG. 25, the mounting bracket 740 may be configured to assist with proper positioning on a panel, e.g . , such that the associated sensor is positioned and oriented towards the absorbent material within the dispenser. The mounting bracket 740 includes similar components as the mounting bracket 540 described above. Thus, repetitive description is omitted for the sake of brevity. However, in the example embodiment shown in FIG. 25, the first feature 712 corresponds to a top wall of the dispenser, and the second feature 714 corresponds to a side wall of the dispenser. The mounting bracket 740 may be configured such that the first positioning feature 742 is engageable with the first feature 712 of the dispenser and the second positioning feature 744 is engageable with the second feature 714.

[0079] These and other modifications and variations to the present invention may be practiced by those of ordinary skill in the art, without departing from the spirit and scope of the present invention, which is more particularly set forth in the appended claims. In addition, it should be understood that aspects of the various embodiments may be interchanged both in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims.
