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. Each actuator is disposed in a fluid chamber. The fluidic die also includes an array of fluid sensors. Each fluid sensor is disposed within a fluid chamber and determines a characteristic within the fluid chamber. A data parser of the fluidic die extracts from an incoming signal, firing instructions and measurement instructions for the fluidic die. The measurement instructions indicate at least one of a peak measurement during a nucleation event and a reference measurement during a non-nucleation event. A firing controller generates firing signals based on the firing instructions and a measurement controller activates, during a measurement interval of a printing cycle for the primitive, a measurement for a selected actuator based on the measurement instructions.

Abstract: An advanced blowout preventer that includes an arrester section and a shear section. The arrester section includes a number or arrester rings that are shaped to extend downwardly. The shape of the arrester rings allows the force of gas flowing out of the well to assist in closing the rings. The arrester section may have a number of arrester rings that cooperate to significantly reduce fluid from flowing in the annulus between a section of drill pipe and the blowout preventer. The advanced blowout preventer may also include a shear section. The shear section is configured to engage and shear a section of pipe using induction.

Abstract: A printing system having a printhead assembly with an integrated distributive processor that provides localized control of the thermal characteristics of a printhead. The printing system includes a controller, a power supply and a printhead assembly. The printhead assembly includes a memory device and distributive processor integrated with an ink driver head. The printhead assembly includes a system and method for measuring thermal characteristics of the printhead, providing feedback to control devices including the distributive processor and making control decisions based upon the measure thermal characteristics.
