Dispenser functionality evaluation
First Claim
1. A method for evaluating dispenser functionality of a dispenser for dispensing a material, comprising:
- measuring a first electrical characteristic of the dispenser across a power supply of the dispenser while no dispense event is being performed;
responsive to the first electrical characteristic being above a first threshold, performing a dispense event to dispense the material, wherein performing the dispense event comprises actuating a motor of the dispenser to dispense the material through a dispenser nozzle of the dispenser; and
responsive to the first electrical characteristic being between the first threshold and a second threshold;
measuring a second electrical characteristic of the dispenser across a load on the power supply while no dispense event is being performed;
responsive to the second electrical characteristic being above a third threshold, performing the dispense event to dispense the material; and
responsive to the second electrical characteristic being below the third threshold, refraining from performing the dispense event.

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.

12. A system, comprising:
-
a pre-dispense evaluation component configured to; measure a first electrical characteristic of a dispenser across a power supply of the dispenser while no dispense event is being performed; responsive to the first electrical characteristic being above a first threshold, perform a dispense event to dispense a material; and responsive to the first electrical characteristic being between the first threshold and a second threshold; measure a second electrical characteristic of the dispenser across a load on the power supply while no dispense event is being performed; responsive to the second electrical characteristic being above a third threshold, perform the dispense event to dispense the material; and responsive to the second electrical characteristic being below the third threshold, refrain from performing the dispense event; and a motor configured to be actuated during the dispense event to dispense the material through a dispenser nozzle of the dispenser. - View Dependent Claims (13, 14, 15)

16. A method for evaluating dispenser functionality of a dispenser for dispensing a material, comprising:
-
determining an expected current measurement for a dispense event of the dispenser; performing the dispense event by dispensing the material, wherein performing the dispense event comprises actuating a motor of the dispenser to dispense the material through a dispenser nozzle of the dispenser; obtaining a measured current measurement of the dispense event of the dispenser; and evaluating the measured current measurement against the expected current measurement to identify a component of the dispenser that is experiencing a problem based upon a time during the dispensing event at which the measured current measurement deviates from the expected current measurement. - View Dependent Claims (17, 18, 19, 20)
