  • Patent number: 6877147
    Abstract: In one embodiment, a computer readable medium comprises at least first instructions and second instructions. The first instructions, when executed, compute a first plurality of routes. Each route of the first plurality of routes corresponds to a respective net of a plurality of nets in an integrated circuit layout, and represents a theoretically optimal route of the respective net according to a graph theory based algorithm. The second instructions, when executed, compare each of the first plurality of routes to a corresponding route of a current plurality of routes, each of the current plurality of routes corresponding to the respective net of the plurality of nets and currently existing in the integrated circuit layout. A method is also contemplated.

  • Publication number: 20050041355
    Abstract: A monitoring and response system including a monitoring device for detecting one or more conditions, a transmission system for sending control codes, and multiple devices for actively performing functions in response to the control codes. The monitoring device may consist of multiple detectors located in different geographic areas. The monitoring device may also be an external system. In the external monitoring device configuration, a centralized monitoring device detects and locates the conditions and transmits this information to the transmission system. The transmission system then transmits control commands to the devices.

  • Patent number: 6834379
    Abstract: A method (and a computer accessible medium comprising one or more instructions which, when executed, implement the method) is contemplated. At least a first timing path is identified in a first timing report corresponding to a first partition of a circuit. For at least one timing constraint applied to the first timing path, a second timing path in a second partition of the circuit that causes the timing constraint is determined. A second timing report comprising the first timing path from the first timing report and the second timing path from the second partition is generated.

  • Patent number: 6801787
    Abstract: A transceiver assembly is designed to receive a controller module or to be inserted into a controller module to form a portable smart card communication device. The transceiver assembly includes a transceiver and a connector to electrically connect the controller module to the transceiver. The controller module establishes a communication link between itself and a smart card by sending and receiving signals and data through the connector. Information is read from the smart card and forwarded to the controller module. Information is transmitted through the transceiver assembly and stored on the smart card. The controller module can easily be disconnected from the transceiver assembly for use with other transceiver assemblies.

  • Publication number: 20040191238
    Abstract: The invention is based on the finding that the secretin receptor is expressed in tissues present in the distal lung of humans. In patient with CF, levels of the receptor are elevated compared to normal tissue. Treatment of tissue by secretin stimulates the movement of negative ions in the tissue. The invention provides methods of treatment of cystic fibrosis or COPD in a patient by administering to said patient an effective amount of an agent which triggers anion efflux in respiratory tissue via the activation of a secretin receptor.

  • Patent number: 6791343
    Abstract: A method is contemplated. According to the method, capacitances in a first resistance/capacitance (RC) extraction corresponding to a circuit are modified. Each capacitance is modified to estimate Miller effect on that capacitance. A ratio of a total capacitance on a first wire after the modification in the first RC extraction to a total capacitance on the first wire before the modification in the first RC extraction is calculated. Capacitances in a second RC extraction that are coupled to the first wire are modified according to the ratio. The second RC extraction is a reduced extraction as compared to the first RC extraction. A timing analysis is performed for the circuit using the second RC extraction with capacitances modified to estimate Miller effect.

  • Publication number: 20040174715
    Abstract: Fiber optic light panel assemblies include a panel member having one or more layers of individual optical fibers arranged in close proximity to each other. One or more of the optical fibers may be completely severed adjacent the light receiving end of the panel member to prevent any light entering the light receiving end from being transmitted through the severed optical fibers. At least some of the severed optical fibers may extend along one or more side edges of the panel member and/or intermediate the side edges. A slot may extend through an unlighted end of the panel member toward the light receiving end intermediate the side edges that sever a number of the optical fibers at the innermost end of the slot. The panel member may also be cut into a plurality of smaller width panel sections to provide gaps between the panel sections.

  • Patent number: 6769878
    Abstract: A turbine blade including an airfoil having a profile in accordance with Table 1 is disclosed. The turbine blade has a plurality of cooling passages extending radially outward through the airfoil. The aerodynamic profile of the airfoil has been reconfigured to further reduce overall heat load to the airfoil while paying particular attention to the leading edge region. Specifically, the airfoil leading edge, which is the life-limiting location of the turbine blade has been reconfigured to lower heat load and allow for increased cooling, thereby increasing turbine blade life.

  • Patent number: 6761536
    Abstract: A gas turbine blade having an airfoil to platform interface configured to minimize thermal and vibratory stresses is disclosed. This configuration minimizes exposure to the conditions that are known to cause high cycle fatigue and low cycle fatigue cracks. The turbine blade incorporates a channel in the platform trailing edge that extends from the platform concave face to the platform convex face and has a portion having a constant radius. The channel extends a sufficient distance into a stress field created by the aerodynamic loading of the turbine blade airfoil in order to redirect the mechanical stresses away from the blade trailing edge while allowing the platform trailing edge region to be more responsive to thermal fluctuations.

  • Patent number: 6733187
    Abstract: Connector assemblies for tightly compacting end portions of a bundle of optical fibers together include a plastic tube surrounding the optical fiber end portions and a metal ferrule surrounding the plastic tube. The metal ferrule is crimped to maintain a compression force on the optical fiber end portions while the plastic tube acts as a buffer to prevent damage to the optical fiber end portions by the metal ferrule and is stiff enough to prevent the compression force from causing the optical end portions to sink into the plastic tube blocking light entering the optical fiber end portions.

  • Patent number: 6727802
    Abstract: A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags (“smart” or “proximity” cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data/information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag.

  • Publication number: 20040066659
    Abstract: Illuminators include transparent light emitting members having a pattern of rounded shallow notches or grooves in one or more surfaces of the members for causing internally reflected light to be emitted from the members. The notches or grooves may be cut using a circular cutting tool. The relative speed of the cutting tool and feed rate of the cutting tool relative to the members may be controlled to produce a roughened surface on the notches or grooves.
