Abstract
A system and method for calibrating fluid detects an actual fluid dispensing characteristic, such as dispensing speed, and automatically adjusts the dispensing characteristic to match an ideal dispensing characteristic. The adjustment is conducted by a controller that controls fluid dispensing based on a function that correlates dispensing speed, a dispensed volume, and a dispensing time. The function allows calibration to occur automatically by converging system operation to the ideal dispensing characteristic, without requiring a user to calibrate the system through manual iterative methods.
Claims20
A fluid calibration system, comprising:
- a fluid dispenser;
- an actuator coupled to the fluid dispenser that controls output of a fluid from the fluid dispenser;
- and
- an actuator control coupled to the actuator, wherein the actuator control automatically adjusts the actuator based on a difference between an actual dispensing characteristic and an ideal dispensing characteristic, and wherein the actual dispensing characteristic is determined based upon a function and the ideal dispensing characteristic is pre-determined.
A calibrated fluid dispensing system, comprising:
- a first fluid dispenser;
- a second fluid dispenser;
- a first actuator coupled to the first fluid dispenser that controls output of a first fluid from the first fluid dispenser;
- a second actuator coupled to the second fluid dispenser that controls output of a second fluid from the second fluid dispenser;
- a first actuator control coupled to the first actuator, wherein the first actuator control automatically adjusts the first actuator based upon a first difference between a first actual dispensing characteristic and a first ideal dispensing characteristic, and wherein the first actual dispensing characteristic is determined based upon a function and the first ideal dispensing characteristic is pre-determined;
- and
- a second actuator control coupled to the second actuator, wherein the second actuator control automatically adjusts the second actuator respectively based upon a difference between a second actual dispensing characteristic and a second ideal dispensing characteristic, and wherein the second actual dispensing characteristic is determined based upon the function and the second ideal dispensing characteristic is pre-determined.
A method for calibrating a fluid dispensing system, comprising:
- detecting an actual dispensing characteristic of a fluid dispenser controlled by an actuator;
- determining a difference between the actual dispensing characteristic and an ideal dispensing characteristic;
- and
- controlling the actuator based on the determined difference and according to a function based a time measured between individual motor encoder pulses.
