Abstract: A single port multi-resonator acoustic resonator device (200, 300, 400, 490) possesses an input impedance that exhibits precisely designed electrical resonances. The device contains at least three parts: a transducer/resonator (201, 301, 401. 491) used both to interface to an external electrical circuit and to transform electrical energy into mechanical (i.e. acoustic) vibrations (and vice versa), and also function as a resonator; a mechanical (i.e. acoustic) resonator (203, 303, 460, 480) and an acoustic coupler (202, 302, 404, 494) that controls the acoustic interaction between the transducer/resonator and the mechanical resonator.

Abstract: A method and apparatus for positioning a fluid ejection device such as an inkjet pen, or a plurality of aligned fluid ejection devices, on a supporting frame known as a printbar for page wide array printing involves provision of datum surfaces on each ejection device in two orthogonally related planes. First datum surfaces on the bottom of the devices support the device in a Z direction and second datum surfaces on opposite generally vertically extending sides of the fluid ejection devices are provided near the remote ends of the devices outwardly of electrical interconnects on each side of the devices. The device interconnects resiliently electrical interconnects mounted on the frame causing rotation of the devices to position the second datum surfaces on the device against positioning surfaces of the printbar to hold each fluid ejection device in correct position.

Abstract: A method of operating an inkjet printer comprises forming an image on a media sheet by ejecting ink from an orifice array of an inkjet printhead at a print zone, capturing moist atmosphere from said printed image at a moisture removal zone and conducting moist atmosphere to said orifice array. An inkjet printing mechanism is provided including means for removing moisture from a printed sheet of media and means for conducting moisture removed from said printed sheet to an inkjet orifice array at a print zone.

Abstract: A method of automatically servicing the orifices of an inkjet printhead particularly beneficial for inexpensive fixed or stationary printhead printers capable or printing onto either a series of discrete media sheets or onto a continuous media web. The method includes orifice servicing at the start of each character printing job and at periodic intervals during completion of print jobs. Printing ink is used for automatic cleaning or flushing of the printhead orifices.

Abstract: The footprint of a document scanning unit such as a copier, facsimile machine or document scanner or combinations thereof is reduced by causing overlap of the leading and trailing edges of long document sheets to be scanned in the document delivery roller system downstream of the scanning station. Differential slippage of the overlapping ends between a drive roller and a pinch roller is provided in a first embodiment. A second embodiment uses a moveable pinch roller in the document delivery system to selectively open and close a gap to permit slippage of the leading and trailing edges of the document. A third embodiment uses three document delivery rollers defining two spaced nips in which the leading and trailing edges of a long document are simultaneously present and a crenellated roller surface to guide the leading edge of the document to the desired nip in the delivery system.

Abstract: A method and apparatus for positioning a fluid ejection device such as an inkjet pen, or a plurality of aligned fluid ejection devices, on a supporting frame known as a printbar for page wide array printing involves provision of datum surfaces on each ejection device extending in three orthogonally related planes. The datum surfaces on the fluid ejection devices mate with positioning surfaces on the printbar to hold each fluid ejection device in correct position. A datum surface on a laterally outwardly extending key on each device is engaged by a biasing spring mounted on the printbar to position the device lengthwise of the printbar and also to prevent incorrect installation of the device.

Abstract: A paper cutter assembly for a printer/plotter is mounted on the printhead carriage for movement therewith to avoid separate mounting and guide structure. A cutter wheel is mounted in a housing for cam induced movement between a raised inactive position and a lower active position by engagement of a cam element carrier mounted for movement in the cutter housing with structure on the printer chassis. The printer platen has a stationary cutter bar which extends in a channel in the platen transversely of the path of paper movement and has a cutter wheel receiving well at one end of the channel into which the cutter wheel drops without contacting the platen or cutter bar at commencement of a cutting operation. Camming surfaces on the platen engage the side of a cutter drive wheel to move the cutter wheel into engagement with the cutter bar and then to raise the cutter wheel to the proper amount of operational overlap of the cutting edges as the cutter assembly moves across the paper path.

Abstract: A modular printer chassis, particularly for large scale printers, includes a lower media module which provides a rigid platen media support surface connected to an upper scanning carriage support module by a plurality of fasteners which are tightened at the time of assembly to thereafter permanently hold the modules, which are accurately positioned with the aid of a gauge at the time of assembly, in place so that the accurate inkjet printhead to media spacing in the print zone is maintained.

Abstract: A flexible skate boot having lower and upper portions made of leather, synthetic leather or similar material is provided with a flexible ankle encircling cuff made of synthetic moldable plastic material capable flexing designed in amounts in the forward and aft and lateral directions to act as an energy storage and release device and without wrinkling so as to minimize discomfort and abrasion on the user's ankle and extend the useful life of the boot. The tongue portion of the boot has a similar molded synthetic flexible panel separating the upper and lower sections of the tongue, the tongue panel being aligned with the flexible ankle encircling cuff which separates the upper and lower parts of the boot from each other. The parts are designed to essentially lock the tongue in the desired frontal position to prevent tongue migration from the desired frontal position during skating.

Abstract: A unitary ink supply tube guiding system for a large format inkjet printer includes a tube guide having a bottom comprising a tube support surface, and generally upwardly, preferably vertically, extending front and rear walls and an anti-buckling wall for confining movement of the ink tubes to prevent tube buckling. The ink tubes are supported throughout a full length to convey ink from stationary reservoirs to printheads mounted on a transversely movable printhead carriage. The tubes are preferably bundled together in at least one vertically extending plane and extend through front and rear substantially parallel reaches joined by a bend. The ink tubes are bundled together along a portion of their length by a protective sheath having wear resistant outer ribs which contact the tube guide. Anti-buckling stretch resistant tension ribs are preferably located along one side of the protective carrier or sheath.

Abstract: A governed performance metal shell bat designed to ensure ball exit speed approximating and not exceeding that of a wood bat of comparable weight and geometry is comprised of a thin wall metal shell filled such as aluminum or titanium or alloys thereof with light weight semi-rigid material such as a syntactic foam in the hitting area, the bat having longitudinal flexibility approximating that of a similarly shaped wood bat and the filler material having a density and hardness correlated with the thickness of the metal shell wall in the hitting area.

Abstract: An end cap assembly for a thin wall tubular ball bat includes an insert sleeve which is closely received inside the barrel end of the bat and defines, with the barrel, a glue chamber into which adhesive is injected to affix the sleeve to the barrel without a mechanical interlock. The end cap is mechanically locked into the sleeve and held in place by a radially projecting locking collar on an axially depending skirt portion of the end cap which is received in an annular recess in the internal cylindrical surface of the sleeve. Abutting shoulders on the end cap and sleeve prevent axial movement of the end cap relative to the sleeve.
