  • Patent number: 7901130
    Abstract: The presently described embodiments are directed to a calibration method and system for thin film thermistors that are locally heated with integrated thin film heaters. Initially, print head temperature is either measured or referenced. Then, transient thermistor resistances are measured and used to determine the thermistor resistance at a higher temperature. Notably, this calibration method is advantageously implemented as a step of an existing process without having to expose the print heads to operating temperatures. In some implementations of the presently described embodiments, trimming of the thermistors may be required once calibrated.

  • Patent number: 7445315
    Abstract: A liquid drop ejector comprising a jet stack, thin film or thick film heaters formed on the surface of the jet stack, and at least one thin film or thick film temperature sensor operative to provide feedback temperature control for the thin film or thick film heater elements is provided. In one form, the liquid drop ejector also has the thin film or thick film heater elements grouped in segments that are operative to be individually controlled. In addition, in another form, the signal lines provided to the liquid drop ejector are patterned to allow for more uniform resistance over the span of the liquid drop ejector.

  • Patent number: 6217151
    Abstract: An acoustic ink print head includes an array of individual emitters. Each of the emitters have a corresponding transducer with a lower electrode, a separate layer of a piezo-electric material located on the lower electrode, and a separate upper electrode provided on the upper surface of the piezo-electric layer. The upper and lower electrodes are connected to a source of conventionally modulated RF power. A dielectric layer is deposited on top of this structure and lenses are etched into the top of the dielectric layer. The lenses focus energy generated by the transducer to a region of the upper surface of a body of liquid located above the transducer. The lenses concentrate sound waves from the transducers thereby disturbing the surface and causing droplets to be emitted. The print head is formed as an array of individual emitters. The upper electrodes of the individual emitter array have varying surface areas dependent upon their location within a row of electrodes and their output efficiencies.
