摘要:
An inkjet printhead assembly (50) for an inkjet printer having a printhead (10) with a plurality of nozzles (24) and data path and control electronics circuitry (56) operably coupled with the printhead (10) for providing image data that control the flow of ink through the nozzles (24). The nozzles (24) are arranged in sections with actuators (28a, 28b) predisposed about each nozzle (24), for causing the nozzles (24) to print. Interconnections (54) between the data path and control electronics circuitry (56) and printhead (10) include DATA, CLOCK, LATCH and ENABLE lines which are used to operate the printhead (10) and, in turn, the nozzles (24) via shift register stages (228). The actuators (28a, 28b) are supported by the shift register stages (228) into which data is shifted from register stage to register stage for loading data that enables the actuators (28a, 28b). The shift registers stages (228) for all actuators (28a, 28b) are located to one side of the print head (10) to facilitate cleaning of the nozzles (24).
摘要:
A method for timing a deflection correcting electrical pulse relative to operational pulses of an asymmetric thermal droplet deflector of a continuous ink jet printer having nozzles, including the steps of generating a line image data with image data values corresponding to the nozzles, the image data values being indicative of desired pixel graytone levels for the nozzles, comparing the image data values to reference values, generating a serial bit stream in the form of a serially arranged bits based on the comparison of the image data values to the reference values, and producing an actuation value that times the deflection correcting electrical pulse in the serial bit stream when the image data value is equal to the reference value being compared to. The deflection correcting electrical pulse is timed to the actuation value in the serial bit stream.
摘要:
An inkjet printhead assembly (50) for an inkjet printer having a printhead (10) with a plurality of nozzles (24) and data path and control electronics circuitry (56) operably coupled with the printhead (10) for providing image data that control the flow of ink through the nozzles (24). The nozzles (24) are arranged in sections with at least two heater elements, an upper heater (28a) and a lower heater (28b), predisposed about each nozzle (24), the heater elements configured to actuate a nozzle (24) for printing. The data path and control electronics circuitry (56) comprises a plurality of shift registers (100, 102) configured to drive the nozzles, causing them to deliver ink in the direction of a receiver media, such as paper. Interconnections (54) between the data path and control electronics circuitry (56) and printhead (10) include DATA, CLOCK, LATCH and ENABLE lines which are used to operate the printhead (10) and, in turn, the nozzles (24) via the shift register stages (100, 102). The number of interconnections are minimized by interleaving data to the shift registers between upper and lower heater elements of the printhead (10) or by interleaving the data on the DATA line to the shift register stages (104, 106) for the upper and lower heater elements.
摘要:
An image processor (14) supporting very high-speed printing. The image processor (14) preferably has two separate connections to a source (12) of the image being printed, e.g., a printer control bus (34) and an image data bus (36). The image processor (14) preferably accepts images from the image source (12) in commonly known graphics file formats, such as the well-known 24-bit, uncompressed TIFF file format. The image processor (14) is a multiprocessor implementation. Preferably, one processor (30) coordinates or “orchestrates” control of the printing system and handshaking with the image source via the printer control bus (34) and the other processor (32) functions as a raster image processor (RIP) processor (52) and accepts and stores images into the printer environment from the image source (12) via the image data bus (36). The RIP processor (52) preferably performs color separation on the image into color planes and transmits each color plane to a separate processing path from that point on in the imaging chain. Each color plane preferably has a separate imaging path out from a shared image data bus (62). This separate path for each color plane preferably includes a band manager (54), a print engine or nozzle controller (60), and a print head (58).

The herein described Adaptive Ergonomic Positioning device (“AEPD”) relates generally to the field of surgery and other medical or healthcare procedures. The AEPD can be adapted for use with most standard surgical tables and surgical chairs where the patient must be positioned prone during a particular procedure. The AEPD may also be used for certain procedures where the patient may be positioned supine. The AEPD support assemblies are highly adjustable and deliver improved ergonomics for both patients and providers. Patients of different morphology can be comfortably positioned in prone with their head and neck in a neutral position, and shoulders in a forward flexed, slightly internally rotated position. The AEPD can be adjusted to accommodate patients with neck and shoulder mobility restrictions, without any effect on provider accessibility to the surgical or treatment site.
摘要:
A ladder assembly for a work vehicle comprises a deck affixed horizontally just below an entry door of the cab. A yoke is pivotally joined to a support member of the deck for rotation about a vertical axis below the deck surface. The yoke has a pair of arms pivotally joined to an upper end of a ladder structure for allowing rotation of the ladder about a horizontal axis. A turnbuckle is coupled between the support structure of the deck and one stringer of the ladder while a mechanical actuator is operatively coupled to the ladder's other stringer and to an arm of the yoke to which the other stringer is attached. Operation of the mechanical actuator moves the ladder reciprocally between a use position and stowed position where the stowed position is parallel to and immediately below the deck.

A biosensor system comprises a capillary substrate, conductive electrode, and a plurality of nanoparticles having an enzyme deposited thereon formed in a cavity at one end of the capillary substrate. The substrate may have an optional reinforcing layer (which may be conductive or non-conductive) and optional insulating layer thereon. A cannula having an optional conductive layer, insulating layer, and reference electrode may also form part of the system.

The present invention relates to compounds of formula (I): wherein; R1 represents hydrogen or C1-3alkyl; n is an integer having a value of 1 to 5; X represents O or NH; Y represents C or N; or a pharmaceutically acceptable salt thereof, have been shown to be inducers of human interferon and may possess an improved profile with respect to known inducers of human interferon, for example enhanced potency. The compounds of the invention may therefore be useful in the treatment of various disorders, in particular the treatment of infectious diseases, cancer, allergic diseases and other inflammatory conditions, and their use as vaccine adjuvants.

摘要:
Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film or similar type of material laminated with triacetate or similar type material on one or both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbornene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths. Thermoforming and press polishing techniques may be used to fabricate/curve the blanks into lenses. The lenses (optical elements) may be used in an injection molding process to add thickness.
