Abstract: An apparatus, system, and method for cooling a lamp assembly is described herein. The apparatus includes an air channel and an axial slot. A flow of air is injected into the air channel of a lamp housing, wherein the lamp housing comprises at least a bulb. The axial slot is located in a reflector housing and has dimensions that enable a constant flow of air through the slot and across the bulb when a predetermined air flow is input to the air channel.

Abstract: In one example in accordance with the present disclosure an apparatus for attaching to a shaft using a wedge is described. The apparatus includes a disc having a longitudinal axis. At least a portion of the disc is insertable into a shaft and is expandable against an inside diameter of the shaft. The disc has a recess at the longitudinal axis. A wedge to be inserted into the recess pushes the portion of the disc that is insertable into the shaft against an inside diameter of the shaft.

Abstract: A printer mechanism includes a printhead to print on a print medium, and a platen located generally adjacent the printhead such that the platen and the printhead define a print zone therebetween. The platen includes a plurality of elongate ribs that project from an upper surface of the platen in a spaced relationship and positioned to contact a lower surface of the print medium such that the print medium bends downwardly between the ribs to provide an undulated section of the print medium with hills and valleys in the print zone. At least one shape control mechanism transforms each of the hills in the print zone into a corresponding valley in an output path adjacent to the print zone and transforms each of the valleys in the print zone into a corresponding hill in the output path.

Abstract: A method of printing includes ejecting ink drops onto a bottom portion of a print media from ink orifices of a first portion of a printhead; after ejecting ink drops from the first portion of the printhead, advancing the print media; and after advancing the print media, ejecting ink drops onto the bottom portion of the print media from ink orifices of a second portion of the printhead. The second portion of the printhead is smaller than the first portion of the printhead and excludes ink orifices toward an end of the printhead opposite a direction of the advancing of the print media.

Abstract: A printing device component may include a base surface and a plurality of ribs extending away from the base surface. Each rib may include a nominal guiding surface, one or more primary transition surfaces, one or more secondary transition surfaces, and one or more angled surfaces. Each primary transition surface may begin at a top surface and end at a secondary transition surface. Each secondary transition surface may begin at a primary transition surface and end at an angled surface. Each angled surface may begin at a secondary transition surface and end at the base surface.

Abstract: Embodiments of electrostatic blower system for use in computer systems or other electronic device, e.g., in inkjet printers for cooling or drying operations, are disclosed. An exemplary method may include arranging a plurality of electrostatic blowers together to increase output pressure. The method may also include positioning the arranged electrostatic blowers directly adjacent a point of use in a printer device. The method may also include directing and accelerating airflow using a corona discharge in each of the plurality of electrostatic blowers for cooling or drying operations in the printer device.

Abstract: The present invention relates to surgical instruments and more specifically to surgical instruments for removing polyps and growths from within a patient's body. The surgical instrument of the present invention comprises an electrically conductive probe and a shape memory alloy filament attached to the working end of the electrically conductive probe. The shape memory alloy has a first working position and a second working position and is capable of acquiring the second working position in response to the passage of electrical current flowing through, and elevating the temperature of the filament.
