Abstract: A printer includes a printhead having first and second elongate printhead modules; and first and second printer controllers receiving print data and processing the print data to output dot data to the printhead, the first printer controller outputting dot data to the first printhead module and the second printer controller outputting dot data to the second printhead module. The first elongate printhead module is informationally isolated from the second elongate printhead module, whereby no dot data passes therebetween. The first printer controller and the second printer controller communicate therebetween a synchronization signal to effect synchronization therebetween.

Abstract: A printing system comprising: a printhead cartridge comprising a printhead; a cradle unit for supporting the printhead cartridge; and an interface at which the cradle unit is removably engageable with the printhead cartridge, the interface comprising connections for connecting the printhead cartridge with a power supply which is remote from the interface and a power regulation circuit for regulating supply of power from the power supply to the printhead cartridge.

Abstract: A printhead is provided having a plurality of nozzle rows which have displaced row portions.

Abstract: Provided is a printhead assembly that includes a printhead mounted on a support structure, said printhead having an ink ejection face, and a print media guide mounted on the support structure for guiding print media past the printhead for printing. The assembly also includes a wicking element mounted on the support structure between the support structure and the print media guide, as well as a pad with an angled contact surface to operatively facilitate the transferral of ink from the printhead to the wicking element. The wicking element is formed from an absorbent material and is positioned in a cavity defined between the print media guide and the support structure.

Abstract: A pressure sensor (30) for sensing fluid pressure in harsh environments such as the air pressure in a tire by providing a chamber (58) partially defined by a flexible membrane (50). The flexible membrane (50) is at least partially formed from conductive material, and the chamber (58) contains a fluid at a reference pressure. The flexible membrane (50) deflects from any pressure difference between the reference pressure and the fluid pressure. A conductive layer (36) within the chamber spaced from the flexible membrane (50) and, associated circuitry (34) incorporating the flexible membrane (50) and the conductive layer (36). The conductive layer (36) and the flexible membrane (50) form capacitor electrodes and the deflection of the flexible membrane (50) changes the capacitance which the associated circuitry (34) converts into an output signal indicative of the fluid pressure.

Abstract: A micro-electromechanical fluid ejection device includes a substrate. A semiconductor layer is positioned on the substrate. The substrate and the semiconductor layer define a fluid inlet chamber. A nozzle chamber defining structure is positioned on the substrate to define a nozzle chamber in fluid communication with the fluid inlet chamber and a fluid ejection port in fluid communication with the nozzle chamber. An actuator is fixed, at one end, to the substrate. The actuator incorporates a heating circuit electrically connected to the semiconductor layer. The heating circuit is configured to generate thermal differential expansion and contraction upon excitation and de-excitation by the semiconductor layer so that the actuator is cyclically displaced relative to the substrate. A fluid ejection member is fixed to an opposite end of the actuator and positioned with respect to the nozzle chamber so that resultant displacement of the fluid ejection member causes fluid to be ejected from the fluid ejection port.

Abstract: A method of processing an image taken with a digital camera including an eye position sensing means said method comprising the step of utilizing the eye position information within the sensed image to process the image in a spatially varying sense, depending upon said location information. The utilizing step can comprises utilizing the eye position information to locate an area of interest within said sensed image. The processing can include the placement of speech bubbles within said image.

Abstract: An ink jet nozzle assembly includes a nozzle chamber having an inlet receiving ink from a reservoir and a nozzle through which ink from the chamber can be ejected. The chamber includes a fixed portion and a movable portion configured such that relative movement in an ejection phase reduces an effective volume of the chamber and alternate relative movement in a refill phase enlarges the effective volume of the chamber. A pair of spaced apart actuating arms is connected with the movable portion and undergo selective differential thermal expansion upon heating so as to effect the relative movement. The inlet is positioned and dimensioned relative to the nozzle such that ink is ejected preferentially from the chamber through the nozzle in droplet form in the ejection phase, and ink is alternately drawn preferentially into the chamber from the reservoir through the inlet in the refill phase.
