  • Publication number: 20070072604
    Abstract: A Point to Multipoint (PMP) multi-hop relay network includes a base station, one or more relay stations and one or more subscriber stations. Active service flows in a PMP multi-hop relay network have a 16-bit connection identifier (CID). A CID defines the connection that a packet is servicing. Before traffic can be transmitted, the path through the network, and the association of CIDs with respective hops needs to be established. The CID mapping relationship from the ingress air link to the egress air link at each relay station is first set up, which is then followed by a traffic phase where the CID mapping relationship is used to route traffic from a base station to a subscriber station.

  • Patent number: 7196801
    Abstract: A method for measuring a characteristic of a substrate, including directing an incident beam at an inspection grid of points on the substrate, receiving the reflected beam with a position sensitive detector, measuring the displacement of the reflected beam from its expected location, compiling a database of the displacement measurements, examining the database for effects of a pattern induced anomaly in the displacement measurements, producing an adjusted database, and deriving the characteristic of the substrate from the adjusted database. Thus, pattern induced errors from the displacement measurements are corrected. In this manner, problems with interpreting the reflection angles of a beam in substrate stress analysis equipment are overcome where distortions in the reflection angles are caused by deposition patterns on the substrates.

  • Patent number: 7190441
    Abstract: Methods and systems for preparing a sample for thin film analysis are provided. One system includes an energy beam source configured to generate an energy beam. The system also includes an energy beam delivery subsystem configured to direct the energy beam to a sample and to modify the energy beam such that the energy beam has a substantially flat-top profile on the sample. The energy beam removes a portion of a contaminant layer on the sample to expose an analysis area of a thin film on the sample.

  • Publication number: 20060256966
    Abstract: A transmitter classifies quantum pulses into supervisory pulses and message pulses, and assigns each message pulse to a message bit. Each message pulse is then encoded using a coding base randomly selected from a set of coding bases, and with a polarity relative to the coding base that depends on the value of the corresponding message bit. Supervisory pulses are encoded using a coding base different from the coding bases in the aforementioned set. The encoded pulses are sent to a recipient over a quantum channel. The transmitter also informs the recipient of the positions of the supervisory pulses. The recipient detects the pulses relative to a locally selected coding base, producing a zero-click, a one-click or a two-click.

  • Publication number: 20050190704
    Abstract: A routing tree that spans a graph representing a network is constructed by iteratively expanding the tree to include a node of the graph that is not in the tree, the node being chosen because an allowable path extends from a root of the tree to the node that is optimal in comparison with the other paths to the other nodes not in the tree. If the path to the node cannot be extended to a node in the serial restriction group, the node is re-included in the tree using a secondary path to the node that can be extended to a node in the serial restriction group, if the secondary path is most optimal among the paths to nodes outside of the tree.

  • Publication number: 20050111375
    Abstract: A method and apparatus for associating metric information with an abstracted link of an abstracted network map that includes certain network elements (NEs) of a data transport network involves computing routes through the data transport network between the NEs of the abstracted network map. The routes may be computed using the shortest widest path algorithm. The routes from an NE are exchanged with the other NEs of the abstracted network map, so that an edge NE receives the resource availability information of all optimal routes between pairs of NEs in the abstracted network map. The edge NE then transforms the resource availability of a corresponding optimal route into metric information of an abstracted link. The metric information is sent to a client associated with the abstracted network map to permit the client to make routing decisions.

  • Publication number: 20050088978
    Abstract: A method of computing allowable routes through a data network that includes a subnetwork that introduces a subnet intransitivity constraint on allowable paths through the network involves using an abstracted network map to construct a directed graph that compensates for the subset intransitivity constraint by removing all unallowable paths. The abstracted network map may be used to compute least cost allowable paths through the network. The directed graph represents the same network, and is constructed by representing bi-directional links between the subnetwork elements with two directed edges, and representing the subnetwork elements as paired ingress and egress nodes. A method for constructing the directed graph representing an abstracted map of a network that exhibits subset intransitivity is also described.

  • Publication number: 20040243653
    Abstract: A system for generating an alarm when an abnormal database backup status occurs includes an alarm module (121) for determining whether an abnormal database backup status exists, and generating and transmitting an alarm message and an alarm email. The alarm module includes a scan sub-module (1211), an alarm message sub-module (1212), an alarm mail sub-module (1213), and a log file sub-module (1214). The scan sub-module is used for scanning the database to identify whether an abnormal backup status exists, wherein the abnormal backup status means that the free space of the database is not enough for storing backup files. The alarm message sub-module is used for sending the alarm message. The alarm mail sub-module is used for sending the alarm email. The log file sub-module is used for recording the abnormal backup status. A related method for generating an alarm when an abnormal database backup status occurs is also provided.

  • Patent number: 6751510
    Abstract: A predictive and self-tuning PI controller includes an apparatus for variably assigning gains thereto in accordance with specified time functions following a change in set-point. The control gains are computed in accordance with a plurality of input parameters and subsequently continuously adjusted to set-point errors based on a GPC approach thereby to optimize performance indices derived from simple and classical user specifications. Variation and tuning of control gains in accordance with set-point errors permits the PI controller to be useful in the general area of process control and applicable to a wider range of processes compared to traditional PI control, including time-delay processes, unstable processes and processes with time-varying dynamics.

  • Patent number: 6697767
    Abstract: This invention provides a novel process identification and control package for high performance. For process identification, a simple yet effective and robust identification method is presented using process step responses to give a continuous transfer function with time-delay without iteration. A new relay, called cascade relay, is devised to get more accurate and reliable points on the process frequency response. For controller tuning, the internal model principle is employed to design single-loop controller PID or high-order types with best achievable control performance. The process identification and control design parts can be easily integrated into control system auto-tuning package. Further, a general control scheme for disturbance rejection is given which can significantly improve disturbance rejection performance over conventional feedback systems with time delays. Practical issues such as noises, real-time implementation and tuning guidelines are also provided.
