Abstract: Systems and methods for identifying a device using a programmable memory circuit having at least one partially blown fuse are described herein. A fluid ejection apparatus includes an electronic controller. The electronic controller is configured to determine a resistance associated with a partially blown fuse in a programmable memory circuit and to determine an identifier based on the resistance.

Abstract: A method of forming a slot in a substrate comprises growing an oxide layer on a first side of a substrate, patterning and etching the oxide layer to form an opening, forming a material overlying the opening and the oxide layer, removing substrate material through a second side to a first distance from the first side, and anisotropic etching the substrate to create a substrate opening at the first side which is aligned with the opening in the oxide layer during anisotropic etching. The material overlying the opening and the oxide layer is selected so that an anisotropic etch rate of the substrate at an interface of the material and the substrate is greater than an anisotropic etch rate of the substrate at an interface of the oxide layer and the substrate.

Abstract: This invention relates to a method for varying a printing speed based upon ink/toner dry time profiles, comprising the steps of: determining a gloss reading of an ink/toner located on a media; determining an actual ink/toner dry time profile for the media; determining the type of media; and adjusting, if possible, a printing speed of a printing device that is utilizing the ink/toner.

Abstract: A fluid ejection system includes a fluid ejection assembly including a plurality of photosensors and a first array of fluid ejection elements. Each of the fluid ejection elements is configured to cause fluid to be ejected when the fluid ejection element is activated. Each one of the photosensors is coupled to a respective one of the fluid ejection elements for activating the fluid ejection element. A first light source emits a light beam. A control system scans the light beam across the fluid ejection assembly and selectively illuminates the photosensors, thereby activating the fluid ejection elements coupled to the illuminated photosensors.

Abstract: This invention relates to a method for grain equalization utilizing double dotting, comprising the steps of: determining a drop weight of each die in a multi-die printhead to print a given ink; determining the highest drop weight amongst all the dies; and determining a percentage of double dotting that is needed to substantially match a grain of the highest drop weight die.

Abstract: A layer of compressive alpha-tantalum is formed on a substrate by depositing a buffer layer on the substrate and depositing a layer of compressive alpha-tantalum on the buffer layer with lattice matching between the layer of compressive alpha-tantalum and the buffer layer. A bias may be applied to the substrate during deposition of the buffer layer and/or compressive alpha-tantalum layer. In some embodiments, the method may include depositing buffers layers comprising titanium, niobium, substantially pure aluminum or aluminum-copper alloy.

Abstract: This invention relates to an apparatus and method for making booklets. Such structures of this type, generally, employ a variety of creasing techniques in order to form the booklet.

Abstract: This invention relates to a Web-based imaging system that provides a print preview. Such systems of this type, generally, allow the user to preview the print job prior to printing of the print job. In particular, if the media to be printed upon is non-white, the system will provide the user with a view of how the print job will look on the non-white media.

Abstract: This invention relates to self-propelled, mobile input/output bins (MIOB). Such structures of this type, generally, allow the MIOB to provide an automated input/output job distribution. For example, the MIOB can provide a method for automated input/output job distribution, comprising the steps of: detecting an input/output job at a consumable handling device; interacting between said consumable handling device and a first self-propelled, mobile input/output bin; and contacting a second self-propelled, mobile input/output bin by said first input/output bin when said first input/output bin becomes full.

Abstract: This invention relates to self-propelled, mobile input/output bins (MIOBs). Such structures of this type, generally, allow several MIOBs to communicate with one another and a data center. For example, the MIOBs can communicate with a data center if one of the MIOBs experiences a breakdown so that MIOB can be sent to assist with the breakdown.

Abstract: This invention relates to a method and apparatus for making booklets. Such structures of this type, generally, employ a saddle, a plurality of skis, and a cutting mechanism to retain and cut individual sheets of media and, subsequent, fasten the individual sheets to form the booklet.

Abstract: This invention relates to an apparatus and method for making booklets. Such structures of this type, generally, employ a variety of creasing techniques in order to form the booklet.
