The dispensing system 100 can include a dispensing device 104. The dispensing device 104 can be attached to the surface 102. In an example, the dispensing device 104 dispenses a material 108 that is stored within the dispensing device 104. The dispensing device 104 can include a housing 110 that defines an interior in which the material 108 is stored. In one possible example, a container 112 is stored within the housing 110. The container 112 defines a substantially hollow interior in which the material 108 is stored. In some examples, the container 112 includes a nozzle 114 through which the material 108 can be selectively dispensed.
The material 108 includes any type of liquid, semi-liquid, gel, powder, foam based materials, etc. The material 108 can include, for example, cleaning materials such as disinfectants, sanitizers, antiseptics, soaps, moisturizers, or the like. In other examples, the material 108 may include water or other non-cleaning liquid materials. Indeed, the material 108 is not specifically limited to these examples, and could include any type of materials.
The dispensing system 100 can include a controller 120. The controller 120, which may include a logic controller (e.g., microcontroller, etc.) or the like, is coupled to the container 112. In an example, the controller 120 can control the dispensing of the material 108 from the container 112. In some examples, the dispensing system 100 includes a proximity sensor 122 that is coupled to the controller 120. The proximity sensor 122 can detect the presence of a user 124 in proximity to the dispensing system 100. The proximity sensor 122 can communicate with the controller 120 to cause the material 108 to be dispensed from the container 112 to the user 124.
The dispensing system 100 can include a sensor assembly 130. In an example, the sensor assembly 130 can be attached to and/or supported by the surface 102. The sensor assembly 130 can be coupled to the dispensing device 104. In some examples, the sensor assembly 130 can detect a size of the user 124 in proximity to the dispensing device 104. As such, the sensor assembly 130 can activate the dispensing device 104 to dispense a quantity of the material 108 that is based on the size of the user 124 detected by the sensor assembly 130.
The sensor assembly 130 can include a first sensor 132 positioned at a first height 134 (e.g., with heights being measured from the ground or floor). The first sensor 132 comprises any number of sensors, including active sensors, passive sensors, infrared sensors, parallel sensors, triangulated sensors, position sensitive devices, time of flight distance sensors, radio frequency signal strength, capacitive sensors, inductive sensors, microwave sensors, optical sensors, or the like. In some examples, the first sensor 132 comprises sonar, ultrasonic, or laser sensors. Indeed, the first sensor 132 can include nearly any type of sensor that can detect the presence of the user 124 without physical contact. In one possible example, the first sensor 132 may detect a temperature difference above a threshold difference from an ambient temperature based upon infrared radiation emitted from the user 124 standing in proximity to the first sensor 132.
The sensor assembly 130 can detect a first size 140 of the user based upon an output from the first sensor 132. In an example, when the user 124 has a size that is at least as great as the first height 134 of the first sensor 132, the first sensor 132 can detect the presence and/or size of the user 124. The first sensor 132 can detect the presence and/or size of the user 124 based on infrared radiation emitted from the user 124. In some examples, the user 124 has a first size 140 that may include a height of the user. In the illustrated example, the first size 140 is less than the first height 134 of the first sensor 132. As such, the first sensor 132 may not detect the user 124 or may detect that the first size 140 of the user 124 is less than the first height 134 of the first sensor 132. In these examples, an output from the first sensor 132 may be transmitted to the controller 120, with the output being indicative of the first size 140 of the user 124.
The sensor assembly 130 can include a second sensor 152 positioned at a second height 154 that is greater than the first height 134. The second sensor 152 comprises any number of sensors, including active sensors, passive sensors, infrared sensors, parallel sensors, triangulated sensors, position sensitive devices, time of flight distance sensors, radio frequency signal strength, capacitive sensors, inductive sensors, microwave sensors, optical sensors, or the like. In some examples, the second sensor 152 comprises sonar, ultrasonic, or laser sensors. Indeed, the second sensor 152 can include nearly any type of sensor that can detect the presence of the user 124 without physical contact. In one possible example, the second sensor 152 may detect a temperature difference above a threshold difference from an ambient temperature based upon infrared radiation emitted from the user 124 standing in proximity to the second sensor 152.

In operation, the user 124 can approach the dispensing system 100. In an example, the dispensing system 100 can detect the presence of the user 124 in proximity to the dispensing device 104. In one possible example, the proximity sensor 122 can detect the user 124 and/or the user's hand(s). In the alternative, the sensor assembly 130 and/or other sensors can be provided to detect the user 124 in proximity to the dispensing device 104.
With the user 124 in proximity to the dispensing device 104, the sensor assembly 130 can detect the size (e.g., first size 140, second size 156, third size 160, etc.) of the user 124. In the illustrated example of
Responsive to the size (e.g., first size 140) of the user 124, the dispensing device 104 can dispense a quantity of the material 108. The dispensing device 104 can dispense a quantity of the material 108 that is based on at least one of the first size 140 of the user 124, the second size 156 of the user 124 or the third size 160 of the user 124. In the illustrated example of

Responsive to the size (e.g., second size 156) of the user 124, the dispensing device 104 can dispense a quantity of the material 108. The dispensing device 104 can dispense a quantity of the material 108 that is based on the second size 156 of the user 124. In the illustrated example, the quantity of the material 108 comprises a second quantity 200 of the material 108 for the second size 156 of the user 124. The second quantity 200 of the material 108 is greater than or equal to the first quantity 170 of the material 108. The controller 120 can control the container 112 and/or the nozzle 114 (e.g., by controlling a valve, pump, or the like) to cause the container 112 to dispense the second quantity 200 of the material 108. As such, the second quantity 200 of the material 108 is dispensed when the sensor assembly 130 (e.g., the first sensor 132) detects the second size 156 of the user 124.

The dispensing device 104 can dispense a quantity of the material 108 that is based on the third size 160 of the user 124. In the illustrated example, the quantity of the material 108 comprises a third quantity 300 of the material 108 for the third size 160 of the user 124. The third quantity 300 of the material 108 may be greater than or equal to the second quantity 200 of the material 108. The controller 120 can control the container 112 and/or the nozzle 114 (e.g., by controlling a valve, pump, or the like) to cause the container 112 to dispense the third quantity 300 of the material 108. As such, the third quantity 200 of the material 108 is dispensed when the sensor assembly 130 (e.g., the first sensor 132 and the second sensor 152) detects the third size 160 of the user 124.

In addition to the first sensor 132 and second sensor 152, the second sensor assembly 400 can include a third sensor 410. In the illustrated example, the third sensor 410 is attached to/supported by a second surface (e.g., a ceiling 420). The third sensor 410 is not limited to being attached to/supported by the second surface (e.g., ceiling 420), and in other examples, could be located on a vertically extending surface that is adjacent the surface 102. The third sensor 410 can be positioned over an area in which the user 124 is located when the user 124 is in proximity to the dispensing device 104.
The third sensor 410 comprises any number of sensors, including active sensors, passive sensors, infrared sensors, parallel sensors, triangulated sensors, position sensitive devices, time of flight distance sensors, radio frequency signal strength, capacitive sensors, inductive sensors, microwave sensors, optical sensors, or the like. In some examples, the third sensor 410 comprises sonar, ultrasonic, or laser sensors. Indeed, the third sensor 410 can include nearly any type of sensor that can detect the presence of the user 124 without physical contact. In one possible example, the third sensor 410 may detect a temperature difference above a threshold difference from an ambient temperature based upon infrared radiation emitted from the user 124 standing in proximity to the third sensor 410.
While the third sensor 410 is illustrated in conjunction with the first sensor 132 and second sensor 152, in some examples, the third sensor 410 may operate independently and/or without the first sensor 132 and/or second sensor 152. In such an example, the third sensor 410 may be provided without the first sensor 132 and/or the second sensor 152. As such, the third sensor 410 can detect the presence of the user 124 and the size of the user 124, and communicate this information to the dispensing device 104.

In an example, the third sensor 410 can detect the presence of the user 124 in proximity to the dispensing device 104 such as by sensing infrared radiation emitted from the user 124. An output from the third sensor 410 may be transmitted to the controller 120 indicating that the user 124 is in proximity to the dispensing device 104. Next, in a similar manner as described above in

In an example, the first sensor 510 comprises a first sensing device 512 and a second sensing device 514. The first sensing device 512 and second sensing device 514 are positioned along a first sensor axis 516 that is horizontal. In one possible example, the first sensing device 512 comprises an emitter that can send out one or more signals. The one or more signals sent out by the first sensing device 512 can include, for example, photons, light pulses, parallel beams, triangulated beams, lasers or the like. These signals can reflect off the user 124. The second sensing device 514 is positioned in proximity to and adjacent to the first sensing device 512. In one possible example, the second sensing device 514 comprises a receiver, such as a photodiode, array of photodiodes, time of flight measurement device, etc. The second sensing device 514 can detect/receive the signals sent out by the first sensing device 512.
The second sensor 520 comprises a first sensing device 522 and a second sensing device 524. The second sensor 520 is identical to the first sensor 510. The first sensing device 522 and second sensing device 524 are positioned along a second sensor axis 526 that is horizontal. In an example, the second sensor axis 526 is parallel with respect to the first sensor axis 516, with the second sensor axis 526 spaced a distance apart (e.g., above) from the first sensor axis 516. In one possible example, the first sensing device 522 comprises an emitter that can send out one or more signals. The one or more signals sent out by the first sensing device 522 can include, for example, photons, light pulses, parallel beams, triangulated beams, lasers or the like. These signals can reflect off the user 124. The second sensing device 524 is positioned in proximity to and adjacent to the first sensing device 522. In one possible example, the second sensing device 524 comprises a receiver, such as a photodiode, array of photodiodes, time of flight measurement device, etc. The second sensing device 524 can detect/receive the signals sent out by the first sensing device 522.
In operation, the first sensing device 512, 522 can send out one or more signals 550. The signals 550 may be directed towards the user 124, who is standing in proximity to the dispensing device 104. In some examples, the signals 550 are reflected off of the user 124 and detected by the second sensing device 514, 524. An output from the second sensing device 514, 524 of the first sensor 510 or second sensor 520 may be transmitted to the controller 120. In some examples, this output can indicate that the user 124 is in proximity to the dispensing device 104. In another example, this output can indicate the size (e.g., first size 140, second size 156, third size 160, etc.) of the user 124. In yet another example, this output can indicate the distance that the user 124 is away from the dispensing device 104. For example, based on time of flight (e.g., time between transmission of signals from first sensing device 512, 522 to second sensing device 514, 524), signal strength (e.g., signal strength received by second sensing device 514, 524), or the like, the distance of the user 124 from the dispensing device 104 can be determined.
In some examples, the third sensor assembly 500 can detect the size of the user 124 without inadvertently detecting the size of a person or object located behind or adjacent the user 124. For example, the first sensor 510 and/or second sensor 520 can detect the size of the user 124. Based on factors related to the signals 550 emitted by the first sensing device 512, 522 and received by the second sensing device 514, 524, the third sensor assembly 500 can determine the size of the user 124 while ignoring, filtering, and/or not detecting the size of people/objects adjacent the user 124. In an example, factors related to the signals 550 can include the strength of the signal 550 received by the second sensing device 514, 524, time of flight between emission and reception of the signals 550, or the like. In such an example, signals that are stronger and/or faster may be indicative of the user 124 and not other people/objects adjacent the user 124. In one possible example, the third sensor assembly 500 can output this information to the controller 120, such that the dispensing device 104 can dispense the quantity of the material 108 that is based on the size of the user 124.
