    Abstract: An example printer includes an actuator selection engine. The actuator selection engine is to determine, for an array including a plurality of fluidic actuators, which fluidic actuators to fire. The printer also includes a balancing engine. The balancing engine is to analyze the determined fluidic actuators to identify a large set of fluidic actuators scheduled to fire substantially simultaneously. The balancing engine is also to schedule the large set of fluidic actuators among a plurality of fire pulse groups. Each fire pulse group may include a subset of the large set of fluidic actuators to be fired at a time distinct from another subset.

    Abstract: In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes an array of fluid actuators grouped into primitives. The fluidic die also includes a fluid actuator controller to selectively activate fluid actuators via activation data. The fluidic 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. The actuator evaluators selectively evaluate an actuator characteristic of a selected fluid actuator based on: an output of an actuator sensor paired with the selected fluid actuator, the activation data, and an evaluation control signal.

    Abstract: A fluidic die includes an array of nozzles, each nozzle to eject a fluid drop in response to a corresponding actuation signal having an actuation value. The fluidic dies includes nozzle select logic to provide, for each nozzle, a nozzle select signal having a select value or a non-select value, with a select value indicating the nozzle is select to eject a fluid drop, a nozzle displacement register to receive displacement bits, each displacement bit corresponding to a different one of the nozzles and having an enable value or a disable value, a disable value indicating a defective nozzle, and actuation logic, for each nozzle having a corresponding nozzle select signal having a select value, the actuation logic to provide an actuation signal having an actuation value to an operational neighboring nozzle instead of to the selected nozzle when the corresponding displacement bit has a disable value.

    Abstract: In one example in accordance with the present disclosure, a fluid ejection die is described. The die includes a number of actuator sensors disposed on the fluid ejection die to sense a characteristic of a corresponding actuator. Each actuator sensor is coupled to a respective actuator and multiple coupled actuator sensors and actuators are grouped as primitives on the fluid ejection die. The die also includes an actuator evaluation die per primitive to evaluate an actuator characteristic of any actuator within the primitive. The die also includes a number of disable devices. Each disable device 1) is coupled to a respective actuator of the number of actuators and 2) disables a corresponding actuator when the corresponding actuator is determined to be malfunctioning.

    Abstract: A fluid ejection die that may include a drive bubble device, a sensor and a sensor control logic. The drive bubble device can include a fluid ejector. Furthermore, the sensor can be operatively connected to the drive bubble device and the sensor control logic can be operatively connected to the sensor. Moreover, the sensor control logic can include a protective circuitry that can be operatively connected between the sensor control logic and the drive bubble device. The protective circuitry can be configured to shunt excess portions of a signal transmitted from the sensor to protect a circuit path to a DBD control circuit.

    Abstract: A circuit (30) and method for controlling a micro-electromechanical system (10) is herein disclosed. In one embodiment of a micro-electromechanical system (10) having top (16) and bottom (14) capacitor plates with a pixel plate (18) movably positioned therebetween, a release voltage sufficient to overcome stiction forces adhering the pixel plate (18) to one of the capacitor plates (14, 16) is applied to the pixel plate (18) to cause the pixel plate (18) to be attracted to the capacitor plate (14, 16) opposite the capacitor plate (14, 16) to with which the pixel plate (18) is in contact. After the pixel plate (18) has moved a predetermined distance away from the capacitor plate (14, 16) to which it had been adhered by stiction forces, the release voltage is removed. Thereafter, a positional voltage is applied to the pixel plate (18) to move the pixel plate (18) to a desired location between the capacitor plates (14, 16). Release and positional voltages are coupled to and decoupled from the pixel plate (18) by one or more switching mechanisms (32, 34).

    Abstract: A method for calibrating a display device (10) comprises controlling an applied voltage to at least one fabry-perot interferometer pixel (32) through a plurality of switches. The at least one fabry-perot interferometer pixel (32) has a top (34, 41, 64) and a bottom (36, 42, 66) plate defining a gap (44, 58) therebetween wherein the at least one fabry-perot interferometer pixel (32) produces a selected output color in response to the applied voltage. The method further includes controlling a test voltage to the at least one fabry-perot interferometer pixel (32) through the plurality of switches (38, 40) during a calibration sequence to determine a gap capacitance in the at least one fabry-perot interferometer (32). The gap capacitance represents the relative position of the top plate (34, 41, 64) with respect to the bottom plate (36, 42, 66).
