摘要： Data relating to the performance of an individual ink-jet printhead is stored in an electrically-readable form on a silicon substrate forming an essential part of the printhead. A template of electrically-detectable structure is created on the substrate at manufacture, and then portions of the structure are removed in accordance with the data desired to be stored. In one embodiment, the digital performance data may be encoded and also read out in serial form using a shift register on the chip.

摘要： A bubble jet printing device is optimized for extended operation by preventing heat buildup within the printhead and ink supply. Several configurations provides for the addition of heat sinks of appropriate dimensions either directly to the printhead or to an electrode board bonded to the printhead. Plated holes through the electrode board increase heat flow away from the printhead. According to another aspect of the invention, the ink supply cartridge has thermally conductive particles dispersed therethrough to effectively increase its capacity to radiate heat away from the printhead.

摘要： Operating an ultrasonic transmitter and receiver includes providing a MEMS composite transducer. The MEMS composite transducer includes a substrate. Portions of the substrate define an outer boundary of a cavity. A first MEMS transducing member includes a first size. A first portion of the first MEMS transducing member is anchored to the substrate. A second portion of the first MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A second MEMS transducing member includes a second size smaller than the first size of the first MEMS transducing member. A first portion of the second MEMS transducing member is anchored to the substrate. A second portion of the second MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A compliant membrane is positioned in contact with the first and second MEMS transducing members. A first portion of the compliant membrane covers the first and second MEMS transducing members. A second portion of the compliant membrane is anchored to the substrate. Electrical pulses are sent to the first MEMS transducing member which causes the first MEMS transducing member and the compliant membrane to vibrate. The vibrations of the first MEMS transducing member and the compliant membrane are transmitted to an object. Echo signals are received from the object. The received echo signals are converted into electrical signals by the second MEMS transducing member.

摘要： An inkjet printhead having a drop ejector array, an ink passageway for providing ink to the drop ejector array, and a thermally actuated degassing unit. The degassing unit itself includes a body enclosing an air chamber, a check valve configured to allow air to vent from the air chamber to ambient when the pressure in the air chamber exceeds ambient air pressure by a predetermined amount. The thermal degassing unit includes a thermally-induced pressure build-up time to increase the pressure in the air chamber. The air chamber is allowed to cool which causes internal pressure to drop below ambient and draws gas out of the ink.

摘要： A printing system includes a movable tray for holding recording media. The movable tray includes spaced-apart reference marks for determining distance traveled by the tray. A reference-mark optical detector is positioned to provide a field of view through which the reference marks pass. An identifying-mark optical detector provides a field of view through which media-type identifying marks on a piece of recording medium pass. A signal processor provides an output relative to: a) amount of reference marks passing through the field of view of the reference-mark optical detector, and b) signal variation in a signal provided by the identifying-mark optical detector. A look-up table includes media identification signal patterns that are correlated to corresponding media types. Finally, a comparator compares the output of the signal processor to the media identification signal patterns in the look-up table in order to identify type of recording medium.

摘要： A method for measuring dimensions of a stack of medium in a media input location of an imaging system, includes emitting light along a direction that is at a predetermined angle with respect to the normal of the planar surface of the media input location. An array of photosensors are disposed along an array direction that lies in a plane defined by the direction of the light and the normal of the planar surface. The photosensors receive a spatially-varying pattern of light reflected from a surface that is substantially parallel to the planar surface of the media input location to provide corresponding electronic signal data from the photosensor array for subsequent transmission to a printing system controller. The varying electronic signal data is used to provide a measurement of the one or more dimensions corresponding to the stack of medium.
