This change can include, for example, allowing or preventing the passage of electrical current through theswitch 218 and the dimensionallyadjustable element 230. It is to be appreciated that electrical current flowing through theswitch 218 is generically/schematically represented inFIG. 2 aselectrical energy 224. In an example, when thesensor 214 does not detect the presence of theuser 206, theswitch 218 can remain open, thus limiting electrical current from flowing through theswitch 218. - The
dispensing system 200 can include the dimensionallyadjustable element 230. The dimensionallyadjustable element 230 is generically/schematically represented inFIG. 2 since the dimensionallyadjustable element 230 includes any number of structures. For example, the dimensionallyadjustable element 230 can include wire(s), cable(s), wiring harness(es), alloy(s), or the like. - In an example, the dimensionally
adjustable element 230 can include a shape memory alloy wire or material. Shape memory alloys (SMAS) are alloys that “remember” a particular shape and can be returned to that shape after being deformed by applying heat to the alloy. SMAS can include, for example, alloys of copper-zinc-aluminum-nickel, copper-aluminum-nickel, and nickel-titanium. - The dimensionally
adjustable element 230 can be dimensionally adjusted. In an example, the dimensional adjustment of the dimensionallyadjustable element 230 includes a change in a length of the dimensionallyadjustable element 230. For example, the change in the length can include increasing the length of the dimensionallyadjustable element 230. In another example, the change in the length can include decreasing the length of the dimensionallyadjustable element 230. The dimensionallyadjustable element 230 is not limited to length changes, however, and in other examples, can include shape changes as well (e.g., bends, curves, undulations, or the like). - The
dispensing system 200 can include adispensing device 240. Thedispensing device 240 can be coupled to the dimensionallyadjustable element 230. Thedispensing device 240 can also be coupled/attached to thenozzle 204, such that thedispensing device 240 can selectively control the dispensing/supplying of material (e.g., a dispense event) from thedispensing system 200. It is to be appreciated that thedispensing device 240 is generically/schematically illustrated inFIG. 2 because thedispensing device 240 includes any number of structures/devices. Indeed, thedispensing device 240 includes any number of structures/devices that are capable of selectively dispensing/supplying material (e.g., dispense event) through thenozzle 204. Thedispensing device 240 can dispense a material (e.g., illustrated inFIGS. 3 to 6 ) that is stored within thedispensing system 200 during a dispense event. - The
dispensing device 240 can include anactuator portion 250. Theactuator portion 250 can actuate the dispense event based upon a movement of theactuator portion 250. Theactuator portion 250 includes, for example, linear actuators, rotary actuators, lever arms, or the like. Indeed, theactuator portion 250 comprises any number of mechanical or electromechanical devices. Theactuator portion 250 can likewise be provided in association with a pump, pumping device or the like. Theactuator portion 250 can be coupled to the dimensionallyadjustable element 230. In an example, theactuator portion 250 is movable, such that movement of theactuator portion 250 can cause the dispensing/supplying of the material (e.g., a dispense event). As such, theactuator portion 250 can be moved in response to the dimensionallyadjustable element 230 being dimensionally adjusted. For example, the length of the dimensionallyadjustable element 230 can be adjusted, such as by being shortened or lengthened. In such an example, this dimensional adjustment (e.g., shortening or lengthening) can cause theactuator portion 250 to move, which likewise triggers the dispense event. - Turning now to
FIG. 3 , an example operation of thedispensing system 200 is illustrated. In this example, theuser 206 can move his/her hand into proximity with thedispensing system 200 to produce a dispense event 300 (illustrated generically/schematically with arrowhead). For example, theuser 206 can move his/her hand underneath thenozzle 204 so as to receivematerial 302 from thedispensing system 200. - The
sensor 214 can detect the presence of theuser 206 in proximity to thedispensing system 200. In response, thesensor 214 can trigger theswitch 218 to close, such thatelectrical energy 224, such as in the form of electrical current flow, can flow through theswitch 218. In an example, the sensor can activate the dimensional adjustment of the dimensionallyadjustable element 230. For example, electrical current can flow from theswitch 218 and through the dimensionallyadjustable element 230. Electrical current flowing through the dimensionallyadjustable element 230 can cause a change in a temperature of the dimensionallyadjustable element 230, such as by producing heat. In response, the dimensional adjustment of the dimensionallyadjustable element 230 can be activated. In an example, the dimensionallyadjustable element 230 can be changed in length by being reduced in length. This reduction in length is illustrated generically/schematically witharrowhead 304. - The dimensional adjustment of the dimensionally
adjustable element 230 can actuate thedispensing device 240 to facilitate the dispenseevent 300. In the illustrated example, the dimensionallyadjustable element 230 is shortened in length (e.g., arrowhead 304). Based upon the dimensional adjustment, the dimensionallyadjustable element 230 can cause movement of theactuator portion 250. Movement of theactuator portion 250 can trigger the dispenseevent 300, thus dispensing thematerial 302 to theuser 206. - Turning now to
FIG. 4 , an example of the dimensionallyadjustable element 230 engaging thedispensing device 240 is illustrated. In this example, thesensor 214 can trigger electrical current to flow through the switch 218 (e.g., when closed) in response to the detection of theuser 206. In the illustrated example, the dimensionallyadjustable element 230 can engage and at least partially be wound around one or more pulleys 400. While six pulleys are illustrated in this example, it is to be understood that any number of pulleys 400 can be provided. The pulleys similarly could include any number of arrangements. In this example, the dimensionallyadjustable element 230 can wrap around afirst pulley 400 a, asecond pulley 400 b, and athird pulley 400 c. - The dimensionally
adjustable element 230, after wrapping around thethird pulley 400 c, can be attached to aspring 406. Thespring 406 is illustrated generically/schematically inFIG. 4 , as thespring 406 includes any number of sizes, shapes, constructions, etc. In general, thespring 406 can be attached at one end to the dimensionallyadjustable element 230 and at an opposing second end to theactuator portion 250. - In operation, the dimensionally
adjustable element 230 can be dimensionally adjusted. For example, in response to an electrical current flow, the dimensionallyadjustable element 230 can be reduced in length (e.g., illustrated as alength reduction 408 with arrowhead). Thislength reduction 408 can deliver a pulling force on thespring 406, which similarly produces a pulling force on theactuator portion 250. Resulting movement of theactuator portion 250 can trigger the dispenseevent 300, thus dispensing thematerial 302 to theuser 206. - Turning now to
FIG. 5 , a second example of the dimensionallyadjustable element 230 engaging thedispensing device 240 is illustrated. In this example, the dimensionallyadjustable element 230 can include a first dimensionallyadjustable element 230 a, a second dimensionallyadjustable element 230 b, and a third dimensionallyadjustable element 230 c. The first dimensionallyadjustable element 230 a can be wrapped around afirst pulley system 500 a. The second dimensionallyadjustable element 230 b can be wrapped around asecond pulley system 500 b. The third dimensionallyadjustable element 230 c can be wrapped around athird pulley system 500 c. In an example, the pulley systems 500 a-500 c can each be movable. As such, individual pulleys within the pulley systems 500 a-500 c can move in response to dimensional adjustment of the dimensionallyadjustable element 230. - In this example, the first, second, and third dimensionally
adjustable elements 230 a-230 c can each be attached to a fourth dimensionallyadjustable element 230 d. The fourth dimensionallyadjustable element 230 d can be wrapped at least partially around afourth pulley 502. In operation, the dimensionallyadjustable elements 230 a-230 d can be dimensionally adjusted. For example, in response to an electrical current flow, the dimensionallyadjustable elements 230 a-230 c can be reduced in length (e.g., illustrated as alength reduction 508 with arrowhead). - The
length reduction 508 can deliver a pulling force on the fourth dimensionallyadjustable element 230 d. Resulting movement of the fourth dimensionallyadjustable element 230 d can deliver a pulling force on thespring 406, which similarly produces a pulling force on theactuator portion 250. As such, movement of theactuator portion 250 can trigger the dispenseevent 300, thus dispensing thematerial 302 to theuser 206. - Turning now to
FIG. 6 , a third example of the dimensionallyadjustable element 230 engaging thedispensing device 240 is illustrated. In this example, the dimensionallyadjustable element 230 is illustrated as including a single dimensionallyadjustable element 230, though in other examples may include a plurality of dimensionallyadjustable elements 230. In this example, the dimensionallyadjustable element 230 can be dimensionally adjusted, such as by experiencing alength reduction 600, in response to electrical current flowing through the dimensionallyadjustable element 230. - The dimensionally
adjustable element 230 can be attached to anactuator portion 602. Theactuator portion 602 is illustrated somewhat generically/schematically. In general, theactuator portion 602 can engage acontainer 604 stored within thehousing 202. Thecontainer 604 can contain, for example, thematerial 302. - In operation, the dimensionally
adjustable element 230 can be dimensionally adjusted. For example, in response to an electrical current flow, the dimensionallyadjustable element 230 can be reduced in length (e.g., length reduction 600). Thislength reduction 600 can deliver a pulling force on theactuator portion 602. Resulting movement of theactuator portion 602 can trigger the dispenseevent 300. In particular, this resulting movement can cause thematerial 302 to flow from thecontainer 604 and through thenozzle 204 to the user. - Although the subject matter has been described in language specific to structural features or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above.
