Abstract
In one example in accordance with the present disclosure, a fluidic die is described. The die includes an array of fluid actuators grouped into primitives. The die also includes an array of actuator evaluators, wherein each actuator evaluator of the fluidic die is coupled to a subset of the array of fluid actuators. A fluid actuator controller groups multiple fluid actuators of the array of fluid actuators into primitives. A primitive size is greater than or equal to a lower limit threshold and the subset of the array of fluid actuators coupled to the actuator evaluation device is less than or equal to the lower limit threshold.
Claims15
A fluidic die comprising:
- an array of fluid actuators grouped into primitives;
- an array of actuator evaluators, each actuator evaluator coupled to a subset of the array of fluid actuators;
- and
- a fluid actuator controller to group multiple fluid actuators of the array of fluid actuators into primitives, wherein:
- a primitive size is greater than or equal to a lower limit threshold;
- and
- the subset of the array of fluid actuators coupled to the actuator evaluation device is less than or equal to the lower limit threshold.
A fluidic die comprising:
- an array of fluid actuators grouped into primitives;
- a number of actuator sensors to receive a signal indicative of a state of a fluid actuator, wherein each actuator sensor is coupled to a respective fluid actuator;
- an array of actuator evaluators wherein each actuator evaluator is coupled to a subset of the array of fluid actuators, to:
- evaluate an actuator state of any fluid actuator within the subset;
- and
- generate an output indicative of the actuator state;
- and
- a fluid actuator controller to group multiple fluid actuators of the array into primitives, wherein:
- a primitive size is greater than or equal to a lower limit threshold;
- the subset of the array of fluid actuators coupled to the actuator evaluation device is less than or equal to the lower limit threshold;
- and
- the primitive size varies.
A method comprising:
- determining a quantity of fluid actuators within a subset of an array of fluid actuators, which subset are coupled to an actuator evaluator;
- setting a lower limit threshold for a primitive size to be greater than or equal to the quantity of fluid actuators within the subset;
- activating a fluid actuator of the primitive to generate a first voltage measured at a corresponding fluid actuator sensor;
- and
- evaluating a state of the fluid actuator at the actuator evaluator based on a comparison of the first voltage and a threshold voltage.
