Abstract: A fluidic die may include a at least one actuator, and fluid flow architecture to flow a first fluid through at least one fluidic channel, and flow a second fluid through the at least one fluidic channel to form a laminar flow between the first fluid and the actuator. The at least one actuator forms a drive bubble from the second fluid to cause the first fluid to be ejected from the fluidic die.

Abstract: In an embodiment, a fluid ejection device includes a die substrate having first and second fluid slots along opposite substrate sides and separated by a substrate central region. First and second internal columns of closed chambers are associated with the first and second slots, respectively, and the internal columns are separated by the central region. Fluidic channels extending across the central region fluidically couple closed chambers from the first internal column with closed chambers from the second internal column. Pump actuators in each closed chamber pump fluid through the channels from slot to slot.
Abstract translation: 在一个实施例中，流体喷射装置包括具有沿着相对基板侧并且被基板中心区分开的第一和第二流体槽的管芯基板。 封闭腔室的第一和第二内部柱分别与第一和第二狭槽相关联，并且内部柱由中心区域分开。 延伸穿过中心区域的流体通道使来自第一内部柱的封闭腔室与来自第二内部柱的闭合腔室流体耦合。 每个封闭腔室中的泵执行器通过通道从槽到槽泵送流体。

Abstract: Examples include a fluid ejection device. The fluid ejection device comprises a fluid ejection die and a control engine. The fluid ejection die comprises nozzles to eject fluid drops and a temperature sensors disposed on the die to sense temperatures associated with nozzles. The control engine determines at least one nozzle characteristic of at least one respective nozzle based at least in part on a temperature change associated with the at least one respective nozzle corresponding to at least one ejection event.

Abstract: Examples include a fluid ejection system. The fluid ejection system comprises a fluid supply reservoir, a fluid ejection die, a fluid delivery subsystem, and a control engine. The fluid ejection die comprises nozzles to eject fluid and at least one temperature sensor disposed on the die to sense a temperature of the fluid ejection die. The fluid delivery subsystem fluidly connects the fluid reservoir and the fluid ejection die, and the fluid delivery subsystem comprises at least one valve to regulate conveyance of fluid from the fluid supply reservoir to the fluid ejection die. The control engine controls the at least one valve to thereby regulate conveyance of fluid from the fluid supply reservoir to the fluid ejection die based at least in part on the temperature of the fluid ejection die.
