摘要： In an embodiment, a method of sensing an ink level includes applying a pre-charge voltage Vp to a sense capacitor to charge the sense capacitor with a charge Q1, sharing Q1 between the sense capacitor and a reference capacitor, causing a reference voltage Vg at the gate of an evaluation transistor, and determining a resistance from drain to source of the evaluation transistor that results from Vg.

摘要： A printhead assembly includes at least one printhead having an internal power supply path, a power regulator providing an offset voltage from the internal power supply path voltage, and multiple primitives. Each primitive includes a group of nozzles, a corresponding group of firing resisters, and a corresponding group of switches. The switches are controllable to couple a selected firing resister between the internal power supply path and the offset voltage to thereby permit electrical current to pass through the selected firing resister to cause a corresponding selected nozzle to fire.

摘要： A drive circuit for an EL device defines a power cycle and performs energy recovery. During a charging phase of the power cycle, a first energy storage device (i.e., inductor) sequentially releases small energy portions from a power source into the EL device. The energy portions incrementally accumulate to create a high energy potential across the EL device. During a discharging phase of the power cycle, a second energy storage device (i.e., inductor) sequentially accepts small energy portions from the EL device to decrementally discharge the EL device. A switching scheme is implemented to pump the energy storage devices to sequentially release or accept the small energy portions. Energy recovery is performed by capturing some of the EL device discharge energy and introducing it back to the EL device during a subsequent charging phase.

摘要： An interconnect structure and method for forming the same for electrically connecting a main contact point with a plurality of use points. The interconnect structure includes a uniform high resistance layer. A low resistance layer is formed on the uniform high resistance layer. The low resistance layer defines first and second conductors extending between a main contact point and corresponding first and second use points. The first conductor has a corresponding conductor width that is, at least in part, based on a resistance between the first and second conductors.
