Abstract: An apparatus for connecting a printer to a cellular radio system. The adapter allows the printer to conduct facsimile operations. The adapter has a facsimile module which includes executable instructions for decoding fax data and processing the fax data to generate print data for printing; a cell radio; one or more communication ports having at least one of the communication ports in communication with the printer; and a data encoder in communication with the facsimile module and the cell radio. The data encoder is configured to convert data transmitted between the facsimile module and the cell radio.

Abstract: An improved multi-fluid jetting device. The jetting device includes a nozzle plate having a substantially planar surface for ejecting a fluid therefrom. The nozzle plate has at least 10 or more nozzles wherein groups of three adjacent nozzles are arranged in a triad orientation and wherein at least two adjacent nozzles in said triad orientation are coupled to two different fluid sources for fluid ejection from said adjacent nozzles substantially perpendicular to said nozzle plate surface.

Abstract: A removable cassette for a photoprinter includes a reservoir containing a consumable source of ink adapted to be used by the photoprinter for printing, and a consumable supply of printable media sheets adapted to be printed upon by the photoprinter using the source of ink. The consumable source of ink for use with the photoprinter, and the printable media sheets for use with the photoprinter in conjunction with the consumable source of ink, wherein the consumable source of ink and the printable media sheets are integrated into the cassette removable from the photoprinter.

Abstract: An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming.

Abstract: In a print head for ink jet printing a nozzle plate with a nozzle array is gold plated. The gold plated nozzle array is bonded to the polymer ink barrier layer on an electronic chip by a thin layer of tantalum, zirconium, titanium or silicon dioxide. The thin layer greatly increases the ability of the surface to bond chemically to the polymer.

Abstract: Data from a patch memory (23) is substituted for that in a system ROM (9) by applying high order addresses to a standard PLA (19) having word lines (FIG. 3, 50a-50p). The address orders are separately applied to EXCLUSIVE OR circuits (27a-27g). The PLA (19) is personalized to activate line (21) at addresses to be substituted and to provide logical zeros to the EXCLUSIVE OR circuits (27a-27g) which change during the patch. Only one word line is required for each continuous patch, which vary in size on a patch-by-patch basis. The circuit is fast and efficient. It can be used for a wide variety of memory substitution applications.

Abstract: For signal storage systems that interrogate a storage cell with a concomitant precharging of the cell signal line, non-linear capacitors are employed to provide automatic selective coupling of the respective signal line to a detector for determination of the cell state. By connecting a plurality of signal lines to a detector through respective non-linear capacitors that assume a significantly enlarged capacitance when the precharge voltage level is asserted, enhanced coupling of the signal line may be achieved and by selectively precharging the signal line to be interrogated, no triggering of enlarged capacitance at other signal lines occurs to load the detection system.In a preferred symmetrical configuration for use with a reference comparison type of detection, shifts in the discharge characteristics for the two comparison inputs to the cell state detector resulting from manufacturing variations tend to cancel, thus permitting more sensitive detection to be employed.
