Abstract: One or more techniques and/or systems are provided for evaluating dispenser functionality of a dispenser for dispensing a material. In an example, a non-loaded electrical characteristic and/or a loaded electrical characteristic of the dispenser may be measured and evaluated to determine whether to perform a dispense event. In another example, current measurements, such as peak current, may be measured during a dispense event. The current measurements may be evaluated to determine whether a problem exists, such as a mechanical stall, a gear train problem, an actuator problem, a pump problem (e.g., a clogged pump), a mechanical impedance, and/or other issue. Such information may be collected, stored as historical data, and/or used to determine whether to perform subsequent dispense events.

Abstract: A dispensing system is provided including a dispensing device that dispenses a material stored within the dispensing system during a dispense event. A dimensionally adjustable element is coupled to the dispensing device. The dimensionally adjustable element can actuate the dispensing device to facilitate the dispense event based upon a dimensional adjustment of the dimensionally adjustable element. A sensor is coupled to the dimensionally adjustable element and can detect a presence of a user in proximity to the dispensing system. The sensor can activate the dimensional adjustment of the dimensionally adjustable element in response to detecting the presence of the user in proximity to the dispensing system. In this manner material can be dispensed from the dispensing system when the user is in proximity to the same.
