    Abstract: In one example a fluid level sensing device is described. The device includes a sensing die having a number of fluid level sensors disposed thereon and a number of control devices, each control device corresponding to one of the number of fluid level sensors. A control device includes a comparing device to determine a state of a corresponding fluid level sensor. A state of the fluid level sensor is selected from the group consisting of a fluid state and a no fluid state. Each control device also includes a non-volatile memory device corresponding to the comparing device to indicate whether the corresponding fluid level sensor is at the fluid state or the no fluid state. A control device also includes a locking device to receive a write command and to irreversibly set the non-volatile memory device to the no fluid state based on the write command.

    Abstract: An exemplary embodiment of the present technique may include a method including monitoring a number of drops of ink released by a print head of a printing device. The method may also include associating the number of drops of ink with a quanta of charge. The method may also include storing the associated quanta of charge in a memory cell of a programmable read-only memory (PROM) device.

    Abstract: An inkjet printhead device, fluid ejection device and method thereof are disclosed. The fluid ejection device includes a fluid supply chamber to store fluid, an ejection chamber including a nozzle and a corresponding ejection member to selectively eject the fluid through the nozzle, and a channel to establish fluid communication between the fluid supply chamber and the ejection chamber. The fluid ejection device also includes a pressure sensor unit having a sensor plate to output a voltage value corresponding to a cross-sectional area of an amount of fluid in the at least ejection chamber.

    Abstract: In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes a number of zones. Each zone includes a number of sets of fluidic devices. Each fluidic device includes a fluid chamber and a fluid actuator disposed in the chamber. Each fluidic device also includes a sensor to sense a characteristic of the zone and an adjustment device. The adjustment device 1) delays a firing signal received from a previous zone as it passes by each set of fluidic devices and 2) adjusts the firing signal as it enters the zone based on a sensed characteristic.

    Abstract: In some examples, a fluid dispensing device includes a plurality of fluidic actuators and a decoder to detect that a first fluidic actuator is to be activated, and detect that a sense measurement is to be performed. In response to detecting that the first fluidic actuator is to be activated and the sense measurement is to be performed, the decoder is to suppress activation of the first fluidic actuator at a first time, and activate the first fluidic actuator at a second time corresponding to a sense measurement interval to perform the sense measurement of the first fluidic actuator.
