Abstract: A synchronized optical clocking signal is provided to a plurality of optical receivers by providing a layer of a high absorption coefficient material, such as SiGe or Ge, on a front surface of a low absorption coefficient substrate, such as silicon. Diodes are formed in the germanium containing layer for receiving an optical signal and converting the optical signal into an electrical signal. An optical clocking signal is shined on the back surface of the silicon substrate. The light has a wavelength long enough so that it penetrates through the silicon substrate to the germanium containing layer. The wavelength is short enough so that the light is absorbed in the germanium containing layer and converted to the electrical clocking signal used for neighboring devices and circuits. The germanium concentration is graded so that minority carriers are quickly swept across junctions of the diodes and collected.

Abstract: Focused imaging of constant size and resolution over a wide range of distances and a wide field of view in object space is provided by a doubly telecentric catadioptric optical system including an external limiting aperture at the juncture of the focal planes of two objectives, with a large-diameter concave spherical or aspheric mirror as the primary objective, and a camera lens as the secondary objective. Constant resolution avoids rescaling of images made at different depths for machine recognition tasks such as OCR, saving computation time and cost, and increasing through-put and accuracy. For digital linescan cameras, constant resolution of the image avoids scanning objects at different line rates for different depths of objects being scanned, thus maximizing speed of the objects and, hence, throughput. The field of view is constant over the entire range of depth and is not limited by the diameter of the camera lens elements.

Abstract: In producing complementary sets of metal-oxide-semiconductor (CMOS) field effect transistors, including nFET and pFET), carrier mobility is enhanced or otherwise regulated through the reacting the material of the gate electrode with a metal to produce a stressed alloy (preferably CoSi2, NiSi, or PdSi) within a transistor gate. In the case of both the nFET and pFET, the inherent stress of the respective alloy results in an opposite stress on the channel of respective transistor. By maintaining opposite stresses in the nFET and pFET alloys or silicides, both types of transistors on a single chip or substrate can achieve an enhanced carrier mobility, thereby improving the performance of CMOS devices and integrated circuits.

Abstract: A secure data processing system having a plurality of resources accessible over a network arrangement such as the Internet and including a server, maintains lists of three categories of access authorization information. A resource list contains path or location information such as a universal resource locator (URL). A profile list maintains a plurality of profile data specifying individual resources or combinations of resources. A user list contains a userID or other data by which a user may be authenticated to the server and one or more profiles freely assignable to respective users. An access control program allows administrator supervision of editing of the lists of user access authorization information. An authorization program performs authorizations to resources for all users based on the profile information of respective users upon completion of editing.

Abstract: In a protection switching method for a passive optical network system, a communication abnormality is detected in at least one active-system virtual path established between an optical line terminal and a subscriber terminal through a transmission path and a network unit. When a communication abnormality is detected in an active-system virtual path, a switch is controlled to switch the transmission paths to establish a standby-system virtual path between the optical line terminal and the subscriber terminal as a communication partner. A protection switching apparatus for a passive optical network system is also disclosed.

Abstract: The invention relates to a computerized method of managing workload within a Workflow-Management-System (WFMS) said WFMS comprising a process model, said process model comprising one or more activities being the nodes of an arbitrary graph, and directed edges of said graph defining a potential control flow within said process-model. The inventions suggests a determination step, wherein the process model is analyzed if a priority execution specification is assigned to said one activity comprising at least one Boolean predicate and a priority level. In a launching step said Boolean predicate is evaluated using a variable value not comprised in the process model but the variable value being comprised in a context of an instance of the process-model. If the Boolean predicate evaluates to TRUE, the launching step launches execution of said one activity in said activity's execution environment with an execution priority specified according to the priority level.

Abstract: An anti-fuse structure that can be programmed at low voltage and current and which potentially consumes very little chip spaces and can be formed interstitially between elements spaced by a minimum lithographic feature size is formed on a composite substrate such as a silicon-on-insulator wafer by etching a contact through an insulator to a support semiconductor layer, preferably in combination with formation of a capacitor-like structure reaching to or into the support layer. The anti-fuse may be programmed either by the selected location of conductor formation and/or damaging a dielectric of the capacitor-like structure. An insulating collar is used to surround a portion of either the conductor or the capacitor-like structure to confine damage to the desired location. Heating effects voltage and noise due to programming currents are effectively isolated to the bulk silicon layer, permitting programming during normal operation of the device.

Abstract: Methods and apparatus for executing a series of sequential tasks existing within a system-level domain of a customer computing system providing provisioning of meta-level domain products are disclosed. For each product or product action (202), one or more sequence of tasks (250–272) is defined. Within each sequence, one or more tasks are defined as milestones (250, 252, 254, 260, 264, 270, 272). The sequence of tasks is executed, and at each milestone task, an enquiry is made of a related meta-level domain feature to determine whether, as a precondition, it has attributes associating it with a customer, and further whether the product feature holds a locking attribute that corresponds with the milestone task. If so, the execution is continued, and the product feature is placed in a locked state such that its attributes cannot be changed until execution of the task sequence is complete.

Abstract: A method and apparatus for utilizing graphical representations of programming objects to reflect the state of programming objects. State reflection is unique in that it reflects the state of programming objects at the time of programming, rather than during execution, in a visual programming language. The visual programming language comprises a set of graphic aspects which are associated with data element states via a set of graphic aspect references. Each programming object used in the visual programming language comprises a set of data elements. The programming objects may be related via super and subclass objects structures. The method detects when a data element has changed its state and reflects that state change in the visual representation of the programming objects and their respective graphic aspects. A list of graphic aspect references points to a number of graphic aspects which may or may not be applicable to the detected state change.

Abstract: A system and method which employ one or more portable hand held computers and one or more servers, allows a field engineer to complete the entire design, deployment, test, optimization, and maintenance cycle required to implement successful communications networks. The engineer may take the portable hand held computer into the field, and make alterations to the components, position of the components, orientation of the components, etc. based on on-site inspection. As these alterations to the computerized model are made, predictions for the effects these changes will have on the communications network are displayed to the engineer. Measurements may also be made using equipment connected to or contained in the portable hand held computer, and these measurements may be used to optimize performance criteria. Information can be transmitted to and from the portable hand held computer and the server to allow for complex processing to be performed.

Abstract: A manufacturing process is migrated from an existing operation to a configure-to-order (CTO) system. As the CTO operation will eliminate the “machine-type model” (MTM) inventory of the existing operation, the emphasis is shifted to the components, or “building blocks”, which will still follow the build-to-stock scheme, due to their long leadtimes, and hence still require inventory. The solution involves an inventory-service trade-off of the new CTO system, resulting in performance gains, in terms of reduced inventory cost and increased service level. Other benefits include better forecast accuracy through parts commonality and risk-pooling, and increased customer demand, as orders will no longer be confined within a restricted set of pre-configured MTMs.

The inkjet printer uses the inkjet recording head.

Abstract: An integrated product data environment for system design and optimization, e.g., a Collaborative Engineering Environment (CEE). The CEE provides a multi-disciplinary engineering team with immediate access to all relevant product information. It is an enterprise system at the program as well as the company levels, managing product information as a program and corporate asset. Product-centric collaborative capabilities for the CEE are provided by extending the functionality of a commercial Product Data Management (PDM) System. Emerging web-centric commercial-off-tho-shelf (COTS) PDM capabilities, object-oriented technologies, associated rapid application development environments, sophisticated engineering toolsets, and COTS computing and communications technologies have been leveraged to establish the CEE for the complex electronic systems integration domain. The CEE offers substantial improvements in productivity, cost savings, cycle time reductions, product integrity and lifetime support of a system.

Abstract: A method and apparatus of combating the problem of interference in master-slave time division duplex indoor wireless networks based on standards, such as the Bluetooth™ standard, is proposed. The method involves a frequency look-ahead scheme in frequency hopping systems, a scheme of monitoring states of master-slave wireless communication links through values recorded in link history counters, and a scheme of scheduling an appropriate slave unit and choosing a suitable packet size to overcome the effect of interfering sources, if any, in the pico-cell.

Abstract: A system and method for parsing an electronic media database structure to produce tagged data that preserves the content, links, and electronic media structure. In particular, HyperText Markup Language (HTML) data is generated as an Interactive Electronic Technical Manual (IETM) (home page) linked into a relative structure of Web pages to support IETM deployment. An extraction process assesses the functionality associated with each node designated for presentation and builds a virtual Web, based on attributes stored in the IETM database. A series of Web pages with links that hierarchically presents IETM data at run time is produced. The method supports a data warehousing strategy that converts any data type eligible within the relational database. This expands support across multiple types of technical and engineering data. The preferred implementation utilizes a relative addressed pure HTML solution viewable in standard Web browsers.

Abstract: A collaborative engineering environment (CEE) enables the effective capture, management, communication, and exploitation of all product related information to a project team. The systematic employment of this information offers substantial improvements in productivity, cost savings, cycle time reductions, product integrity, and lifetime supportability of the system. Advanced CEE capabilities exploit and leverage the engineering, architectural and technological expertise of enterprise subject matter experts (domain experts) across multiple complex systems development and integration activities. The CEE provides a tightly coupled process automation using reusable product elements for coupling information with engineering processes and ensuring adherence to repeatable and traceable engineering processes.

Abstract: The active/passive absorber for extended vibration and sound radiation control includes principally two layers. The first layer has a low stiffness per unit area which allows motion in the direction perpendicular to its main plane. The second layer is principally a mass layer. These two combined layers have a frequency of resonance close to one of the main structure. The dynamic behavior of the coupled system makes the active/passive absorber a passive absorber; however, the first layer can be electrically actuated to induce motion in the direction perpendicular to its main plane. This addition property induces and/or changes the motion of the mass layer and therefore improves the dynamic properties of the active/passive absorber system. The acive/passive absorber can have multiple mass layers and multiple elastic layers stacked one on top of the other. In addition, the mass layers can be continuous or discretized, and have varying thicknesses and shapes for sections and/or segments in the mass layer.

Abstract: An inkjet recording head includes nozzles arrayed in one direction and ink droplet ejecting devices formed in the respective nozzles. Each nozzle has a height difference in a depthwise direction on a side on which ink droplets are ejected and an ink liquid surface is formed between both edges forming the height difference. An inkjet printer uses this inkjet recording head. The inkjet recording head can eject ink obliquely to the ejection surface for correcting recording pitches at joining portions and preventing the periphery of the nozzles from being contaminated by the ink splashed back from image receiving paper. The ejection angle and the ejecting direction can also be suitably selected and adjusted.

Abstract: Pages of books are copied without distortion due to curvature of the page near the book binding or the distortion in a copied page is corrected using the spacing of equidistant bars on tape strips applied to the top and bottom edges of a page before copying. The tape is preferably transparent and rather narrow and easily attached to a page to be copied. The first step in the distortion correction procedure is to locate the bars at the top and bottom of the page. The distortion of the spacing between the imaged bars is computed based on the known distance between the equidistant bars. The computed distortion of the spacing is then input to a distortion correction algorithm. The output of the distortion correction algorithm generates a corrected image. This image may also optionally delete the bars so that they are not printed in the copy. The corrected image is then copied.
