    摘要： Micro-fluid ejection device actuator chips and methods of measuring temperature of a micro-fluid ejection device actuator chip are provided. An exemplary micro-fluid ejection device includes an actuator chip for delivering fluid from the device. In one such device, one or more fluid vias include a column of actuators per at least one of the sides of the vias that are apportioned into temperature zones. A temperature sense element or resistor (TSR), per each of the zones, measures a temperature therefor. In this manner, average die or chip temperature along a length of the one or more vias can be controlled closer to a predetermined value. In various aspects, individual actuators are apportioned into zones and dedicated TSRs sense temperatures of the zones. In turn, corrective action may be caused to increase or decrease temperature as the case may be. Representative zones include three per each side of a fluid via. Mono- and multi-colored chips are also contemplated as are inkjet printers and other external devices.

    摘要： A printing apparatus is provided that precisely control the transition of an electrical signal that causes a printing substance to be deposited. In particular, in some embodiments, a circuit is configured to control the application of a firing pulse to a printing element, and the printing element is configured to control the application of a printing substance. The circuit in this embodiment is configured to condition or control the transition of the firing pulse from the first state to the second state such that current through the printing element dissipates to zero over a period of tine that is neither too fast nor too slow.

    摘要： Disclosed is a method and/or apparatus for adjusting the sample time and order associated with a digital correction system for maximizing output power and minimizing power stage delay sensitivity of a switching power stage. In certain embodiments, the sample point of an ADC may be changed as a function of the duty ratio of the PWM signal thus allowing higher performance and use of less expensive power stage components. In addition, adjustment of the order of an integrating error amplifier in the system permits operation of the power stage with an output being permitted to saturate up to the power supply rails, thus increasing a power output of the power stage.

    摘要： A fluid cartridge has a bottle to retain a volume of fluid. An ejector chip resides in fluid communication with the bottle and causes ejection of fluid upon activation of fluid ejectors. Control logic coordinates ejector activation with dose control logic and temperature control circuitry. The dose control logic pre-specifies an amount of fluid to be ejected and prevents further ejection upon reaching the amount. Meanwhile, the temperature control circuit inhibits any ejection until a temperature of the fluid is within a predefined acceptable range. Bottle modularity, fluid dispense-areas and group-control of the ejectors facilitate certain designs.
