    Abstract: A fluid reservoir (101) includes a number of electrode pairs disposed within the fluid reservoir. Each of the electrode pairs includes a number of sensing electrodes (103), and a number of electrical traces (105) wherein the sensing electrodes are coupled to a respective one of the electrical traces. The fluid reservoir also includes a common electrode (104) electrically coupled to a voltage source (106). A number of properties of a fluid (110) within the fluid reservoir are detected by applying a voltage between the sensing electrodes in an electrode pair, and a level of the fluid within the fluid reservoir is detected by applying a voltage between the electrodes and the common electrode. A multiplexer (102) may be used to selectively couple the sensing electrodes (103) to a processing device (108). The fluid reservoir may be a printing fluid container.

    Abstract: First electronics may determine a count of bubble jet resistors to be fired by a fire pulse group. A fire pulse generator may generate a fire pulse train for bubble jet resistors, the fire pulse train comprising a precursor pulse and a firing pulse separated by a dead time. Second electronics may adjust a width of the fire pulse for the bubble jet resistors of the fire pulse group by maintaining a first edge of the fire pulse relative to the precursor pulse and adjusting a second edge of the fire pulse relative to the precursor pulse based upon the determined count for the fire pulse group.
