A system and method for simulating a plurality of networked program logic controllers includes, in one aspect of the invention, determining if a configuration of networked program logic controllers exists; populating a configuration by creating a plurality of program logic controllers in a network if the configuration does not exist, the populating of the program logic controllers provided by use of a network view for collecting network information; and interacting with at least one of the program logic controllers to simulate a networked program logic controller.

System and method for encapsulating edges of a paper in digital printing systems. A spray applicator can include a set of stationary sprayers with spray nozzles, a set of transfer rollers and an inkjet print head. The stationary sprayers can be positioned at both marginal ends of the paper. The stationary sprayers apply the fluid through the spray nozzles at edges of the moving paper to encapsulate the edges of the paper such that loose paper fibers and debris are bound to the paper. The fluid can be applied when the transfer rollers can pass the moving paper through a printer or printing press. Thus, the system can protect various subsystems of the printer or printing press against contamination due to the loose paper fibers and debris.

A pachymeter apparatus for measuring corneal thickness is configured for the calculation of intraocular pressure (“IOP”). The apparatus includes a pachymeter for measuring corneal thickness as well as a microprocessor and a user interface. A reading of IOP from a tonometer can be entered into the device and corrected according to the pachymeter reading of corneal thickness. Correction algorithms are user selectable and user customizable. A pachymeter may have a graphical display which displays multiple locations at which measurements are to be taken. A pachymeter may use a capacitor charged by a variable current supply to measure times for signals to be reflected from a back side of a cornea.

A planar magnetic acoustical transducer including a diaphragm with electrical circuit carrying conductors having a width substantially equal to a combined width of a plurality of magnetic fields created by equally spaced opposing rows of permanent magnets carried by opposing frame sections between which the diaphragm is mounted such that substantially the entire active area of the diaphragm is driven to create a smooth frequency response. The electrical circuit includes generally parallel segments which are aligned within the magnetic fields created by the rows of opposing magnets and are spaced at a distance relative to one another generally not less than a distance equal to a width of pole elements which are integrally formed with the frame sections and which pole elements are spaced intermediate each of the rows of magnets so as to be in an opposing relationship with one another on opposite sides of the diaphragm.

A method and apparatus for document verification exploits a temporally variable physical process to generate a reproducible effect that cannot be copied. A document such as a credit card is provided with a spot or stripe that incorporates at least one, and preferably a large plurality of photorefractive crystals arrayed in a random manner. The document verifying apparatus includes a coherent light source such as a diode laser to illuminate the photorefractive crystals, and a photosensor to receive light scattered from the photorefractive crystals. The random distribution and orientation of photorefractive crystals comprises a unique characteristic for each card or document, and this characteristic is not based on any assigned number or code. The response of photorefractive crystals to the coherent illumination comprises a time-varying characteristic that is dependent upon the intensity and temporal nature of the illumination itself. Input to the laser illuminator may be varied to elicit differing responses from the photorefractive crystals, and this factor may be very difficult for a counterfeiter to ascertain. Also, for any given illumination intensity or temporal pattern, the image received by the photosensor varies with time. The time at which the photosensor signal is sampled to obtain an identifying image may also be varied, thereby further compounding the difficulty for a counterfeiter to overcome. A large number of "snapshots" of the time-varying image of the document is electronically captured, digitized, and stored in an electronic media. The photosensor signal is compared to the stored data; a match indicates a valid document, and no match indicates an invalid or unauthorized document. The image recognition process can be enhanced by comparing the rate of change in a sequence of images elicited by the laser illuminator.

A maintenance assembly for cleaning a plurality of printheads in a printing machine comprises two or more cleaning members, each of the cleaning members sized and positioned to clean at least one but less than all of the plurality of printheads when in a cleaning position. A drive mechanism associated with each of the two or more cleaning members is configured to selectively move an associated cleaning member to and from the cleaning position and a retracted position. The cleaning members are supported on a frame with a mechanism provided for translating the frame into position juxtaposed with the plurality of printheads and a further mechanism to swipe the cleaning members across the printheads. The maintenance assembly is operable to clean only selected printheads in a single operation.
