  • Patent number: 7429402
    Abstract: In one embodiment, a method for depositing a tungsten-containing film on a substrate is provided which includes depositing a barrier layer on the substrate, such as a titanium or tantalum containing barrier layer and depositing a ruthenium layer on the barrier layer. The method further includes depositing a tungsten nucleation layer on the ruthenium layer and depositing a tungsten bulk layer on the tungsten nucleation layer. The barrier layer, the ruthenium layer, the tungsten nucleation layer and the tungsten bulk layer are independently deposited by an ALD process, a CVD process or a PVD process, preferably by an ALD process. In some examples, the substrate is exposed to a soak process prior to depositing a subsequent layer, such as between the deposition of the barrier layer and the ruthenium layer, the ruthenium layer and the tungsten nucleation layer or the tungsten nucleation layer and the tungsten bulk layer.

  • Publication number: 20080229261
    Abstract: A software design rule system is provided. The software design rule system can employ a rule language that enables software developers to model valid interactions between multiple, inter-related objects; provide a rule verifier component that determines whether design rules achieve their intended purpose; and provide a rule enforcer component that determines whether the software complies with the specified rules. Software designers can provide design specifications using the rule language that the software design rule system employs. The rule language can specify a program that identifies “auxiliary states” associated with objects in the software that is being developed, transitions between the auxiliary states, and object invariants.

  • Patent number: 7424562
    Abstract: A bridging device has at least two ports. The first port allows the device to communicate with devices on an expansion bus and at least one other port to allow the bridge to communicate with a system memory on a system bus or other devices on another expansion bus. The device is capable of identifying at least two regions in memory, a descriptor region and a data region. A descriptor provides information about segments of data in the data region. The bridge may detect descriptors read from the memory, extract information related to data associated with those descriptors and use this information to perform prefetching of data from the system memory.

  • Publication number: 20080209028
    Abstract: A device, system, and method are directed towards determining network information. A network address is determined for a possible proxy. A determination is made whether a port on the possible proxy is open and/or if the port supports an HyperText Transfer Protocol (HTTP) proxy request. A request is sent to the possible proxy over the port, the request being configured to be forwarded to a network device. A type of the possible proxy is determined based in part on a behavior of the network device. The behavior may indicate whether the request is received by the network device, or whether the possible proxy obscures an origin of the request. The proxy type may include whether the possible proxy is a non-proxy, an anonymous-proxy, a controlled-proxy, and/or an open-proxy. Various types of network analysis may then be performed using the possible proxy and the determined proxy type.

  • Patent number: 7392424
    Abstract: A router and routing protocol redundancy are disclosed to reduce service outage or degradation for a network device and thus to increase service availability on a network due to software and hardware failures of the network device. A network device such as router includes a redundancy platform having an active controller system and a standby controller system. A routing protocol state change is received or generated by the active controller system. The received or generated routing protocol state change is replicated to the standby controller system. By replicating the routing protocol state change, the standby controller system can maintain the routing protocol sessions for the network device if a failure occurs in the active controller system. Furthermore, the routing protocol states are maintained in realtime to handle the dynamic changes created by routing protocols.

  • Publication number: 20080147471
    Abstract: The present invention discloses a method and system for scheduling topic based meetings. The method allows users to update their interests, profile, role etc., and the organizer of the meeting to define objective and agenda of the meeting, based on which the system intelligently assembles the set of users among whom the meeting has to be scheduled on a per topic basis. Once this set has been constructed, a regular scheduling algorithm is applied to arrange a meeting among the interested users. The scheduling process is distributed across various agents acting on behalf of the users among whom the meeting is arranged. Topic based meeting scheduler allows users with similar interests to schedule meetings based on common interests. The method and system of the present invention reduces the time in organizing the meeting among users required to attend, thus improving the efficiency of the group and making collaboration in an efficient manner.

  • Patent number: 7378805
    Abstract: This invention presents a single-stage power converter for driving many number of Light-Emitting-Diode (LED). The power converter converts an AC input voltage into DC current source and regulates the current flowing into the LED. In addition, the AC input current is controlled to have a sinusoidal waveform synchronized with the AC input voltage so that AC input Power Factor is corrected. Hence, both of Power Factor Correction (PFC) and LED current regulation are obtained simultaneously by using a single power conversion stage. So higher efficiency with low cost can be obtained.
