  • Patent number: 6118419
    Abstract: A method and apparatus for detecting random electrostatic discharge events is disclosed in which the electrostatic discharge indicator is "Electric Paper". The "Electric Paper" has a plurality of spheres having one hemisphere of one color and the other hemisphere of another color. The spheres rotate when an electric field is applied to them and are sensitive enough to respond to electrostatic discharge events. The "Electric Paper" may be pre-imaged so that a pattern indicating the state of the paper is visually ascertainable.

  • Patent number: 6116718
    Abstract: A print head is disclosed for use in a marking apparatus in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration.

  • Patent number: 6119156
    Abstract: In an SNMP-based network management system, an agent within the system maintains a quantity of memory which serves as a "lock table." The lock table is a set of object identifiers (OID's) relating to objects associated with the agent. When a manager on the network requests a particular object associated with the agent, the agent retains the OID of the object in the lock table. If another manager simultaneously wishes to set an object associated with the agent, the OID of the proposed object is compared to any OID currently in the lock table, and if the proposed object intersects with one of the objects in the lock table, access to the object is denied. The method permits locking of specific objects, while leaving other objects associated with the same device available to others.

  • Patent number: 6118900
    Abstract: Disclosed herein are easy-to-realize multivalued image coding and decoding devices, each of which is capable of reducing memories in number while the accuracy of calculations necessary upon coding and decoding is being held and relaxing a probability estimate. An image disassembler disassembles a bit string indicative of pixels into a plurality of parts in response to image data inputted from an image input unit. Further, the image disassembler sends the value of each disassembled pixel to be coded and the value of each disassembled pixel for reference to an image analyzer as disassembled image data. The image analyzer sends the value of each disassembled pixel to be coded to a coding unit as disassembled pixel-value data and transmits the value of the reference pixel to a probability estimate unit as status data. The probability estimate unit sends probability estimate data corresponding to the status data to the coding unit.

  • Patent number: 6116596
    Abstract: An improvement in sheet sorters in which movable bins are incremented past a sheet entrance and the bins are cantilever-mounted and incremented in the sorter from only one side of the bins. The unsupported side or end of at least one of the cantilevered bins is temporarily supported to prevent its sagging from the weight of sheets loaded therein, or other causes. Specifically, the free end of the bin which is currently in position to receive sheets entering the sorter from the sheet entrance is supported by a small rotatably driven indexing bin support, such as a star-wheel, which is mounted to allow unrestricted access to the bins for the removal of stacks of sorted sheets.

  • Patent number: 6119052
    Abstract: A market based controller controls the motion of an object on a transport assembly. The transport assembly is formed using sensors and actuators that are proximately coupled in physical space. To efficiently allocate a fixed amount of air pressure directed to the actuators, the market controller maps each market agent to points in space on the transport assembly, as well as, points in time relative to a system clock. Using information gathered from the sensor units, each market agent determines whether to bid on the fixed amount of air pressure each bid interval. Using the bids submitted by the market agents, a market equilibrium price and quantity are computed by a market auctioneer. The air pressure purchased by each market agent is then distributed to the actuators mapped thereto.

  • Patent number: 6113231
    Abstract: An apparatus and related method for high speed offset ink jet printing are provided. Multiple print head modules form a full width ink image by ejecting ink drops onto an intermediate transfer surface on a rotating drum. One or more complete images are formed on the intermediate transfer surface in less than one revolution of the drum. The images are then transferred to a final receiving medium while additional images are simultaneously formed on the intermediate transfer surface as the drum continues to rotate. Two or more color component images may be overlayed to form a complete color image in less than one revolution of the drum. Additionally, the simultaneous imaging and image transfer allow the apparatus and method to print images having a length greater than the circumference of the drum.

  • Patent number: 6115718
    Abstract: A method and apparatus for predicting document access within a collection of linked documents. The present invention utilizes a predictive technique known as "spreading activation" where document collections are graphically represented as a network. Empirical data is analyzed according to a law of surfing to generate a decay function which is used to dampen the activation as spreads through the network. Activation is applied to a set of focus documents and propagates through the network until a stable pattern of activation is achieved across all documents. From this stable pattern, the desired usage information is extracted. Such a system will provide several practical benefits to users of the World Wide Web. For example, the present invention can be used to identify relevant pages to a set of one or more focus pages or to predict the number of times a document will be accessed in a collection of linked documents.

    Abstract: A light collector for directing light to a concentrated area on a target surface such as for use with a linear LED array used as an erase lamp in an electrophotographic printer. The collector includes a compound cylinder lens supported by a pair of reflecting members. The reflecting members reflect light rays from the LED array to the cylinder lens. The cylinder lens includes a lower surface for capturing the reflected light rays and a tongue extending from the lower surface for capturing light rays directly from the LED array. The cylinder lens directs and concentrates the captured light rays in a narrow line on a target surface.

  • Patent number: 6115136
    Abstract: A mark is provided on an object surface of an object under measurement, and the mark provides two intersection points P.sub.1 and P.sub.2 between first and second straight lines L.sub.1, L.sub.2, and between second and third lines L.sub.2, L.sub.3, in which an angle ".alpha." defined by the first and second straight lines L.sub.1 and L.sub.2, another angle ".beta." defined by the second and third straight lines L.sub.2 and L.sub.3, and a distance between P.sub.1 and P.sub.2 are known. This mark is imaged on at least one set of one-dimensional optical sensor. When a sensor signal having a light intensity distribution along a longitudinal direction is outputted from the one-directional optical sensor, a calculation unit calculates positions of the straight lines L.sub.1 to L.sub.3 of the mark image on the one-dimensional optical sensor in response to the sensor signal. Based upon this calculation result, another calculation is made of at least one position of the two intersection points P.sub.1 and P.sub.
