DISPENSER FUNCTIONALITY EVALUATION
First Claim
1. A method for evaluating dispenser functionality of a dispenser for dispensing a material, comprising:
- measuring a non-loaded electrical characteristic of a dispenser;
responsive to the non-loaded electrical characteristic being above a first non-loaded threshold, performing a dispense event; and
responsive to the non-loaded electrical characteristic being between the first non-loaded threshold and a second non-loaded threshold;
measuring a loaded electrical characteristic of the dispenser;
responsive to the loaded electrical characteristic being above a loaded threshold, performing the dispense event; and
responsive to the loaded electrical characteristic being below the loaded 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.

13. A system for evaluating dispenser functionality of a dispenser for dispensing a material, comprising:
a pre-dispense evaluation component configured to; measure a non-loaded electrical characteristic of a dispenser; responsive to the non-loaded electrical characteristic being above a first non-loaded threshold, perform a dispense event; and responsive to the non-loaded electrical characteristic being between the first non-loaded threshold and a second non-loaded threshold; measure a loaded electrical characteristic of the dispenser; responsive to the loaded electrical characteristic being above a loaded threshold, perform the dispense event; and responsive to the loaded electrical characteristic being below the loaded threshold, refrain from performing the dispense event. - View Dependent Claims (14, 15, 16)

17. A method for evaluating dispenser functionality of a dispenser for dispensing a material, comprising:
-
determining an expected current for a dispense event of a dispenser based upon a non-loaded voltage of the dispenser; obtaining a current measurement of a current dispense event of the dispenser; evaluating the current measurement against the expected current to determine an operational characteristic of the dispenser; and providing the operational characteristic. - View Dependent Claims (18, 19, 20)
