Abstract: One example provides a printhead including a plurality of printhead dies, each printhead die including at least one crack sense resistor. At least one analog bus is connected to each printhead die, the at least one analog bus to output voltages to facilitate a printer controller to determine whether at least one of the printhead dies is cracked.

Abstract: The viscosity of a fluid may be determined using a flow rate determination. The flow rate may be determined based on fluid presence determinations within a capillary channel. Also, a temperature of an environment surrounding a capillary channel may be determined and signals may be transmitted to a thermal element responsive to the determined temperature.

Abstract: A fluidic die includes a number of sensors to measure properties of a number of property control elements associated with the printhead die, a pass gate to communicate a number of signals to an application specific integrated circuit (ASIC) via an analog bus using control logic associated with the pass gate, and a bi-directional configuration bus coupled to the fluidic die to transmit a number of control signals to property control elements located on the fluidic die.

Abstract: A method may include maintaining a sample comprising an ionic species and an optical indicator at an elevated temperature above 25° C. on a semi-conductive microfluidic die during an incubation period, intermittently interrogating the sample with an interrogating light during the incubation period and sensing a response of the sample to the interrogating light, wherein the sample is interrogated with the interrogating light only during those times at which the sample is being sensed.
