MONITORING CIRCUITRY INCLUDING LEVEL SHIFTERS AND ANALOG PASS GATES
According to examples, an apparatus may include fluid chambers that each includes a fluid actuator and an electrode. The fluid actuators may operate at a first voltage level and a monitoring circuitry may operate at a second voltage level that is lower than the first voltage level. The monitoring circuitry may monitor a condition of each fluid chamber based on a selection signal for selecting an electrode associated with a fluid chamber. The monitoring circuitry including an analog multiplexer that includes, for each of the electrodes for the plurality of fluid chambers, a level shifter to receive the selection signal at the second voltage level and to shift a level of the selection signal. The analog multiplexer may also include an analog pass gate to selectively couple the electrode of a respective fluid chamber to the monitoring circuitry based on the level shifted selection signal.
B41J 2/045 - Machines à écrire ou mécanismes d'impression sélective caractérisés par le procédé d'impression ou de marquage pour lequel ils sont conçus caractérisés par la mise en contact sélective d'un liquide ou de particules avec un matériau d'impression à jet d'encre caractérisés par le procédé de formation du jet en produisant à la demande des gouttelettes ou des particules séparées les unes des autres par pression, p.ex. à l'aide de transducteurs électromécaniques
In an example implementation according to aspects of the present disclosure, a system includes a thermal sensor and a processor. The processor determines that a workload surpasses a high workload threshold. The processor determines that the workload transcends a low workload threshold after the workload abates. The processor determines a measured thermolysis curve based on a reading from the thermal sensor. The processor compares the measured thermolysis curve against a target thermolysis curve and generates a filter event based on the comparing.
