  • Publication number: 20090184869
    Abstract: Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple GNSS, where at least one GNSS is FDMA. Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities. The scheme enables GLONASS carrier phase ambiguities to be resolved and used in a combined FDMA/CDMA (e.g., GLONASS/GPS) centimeter-level solution.

  • Publication number: 20090086118
    Abstract: An array substrate includes first and second gate lines, a data line, a pixel electrode, a domain electrode, first, second and third switching elements, and a voltage-changing part. The domain-dividing electrode divides the first and second pixel parts into a plurality of areas. The first, second and third switching elements are controlled by a first gate signal applied from the first gate line. The first, second and third switching elements apply a data signal received from the data line to the first and second pixel parts and the domain-dividing electrode, respectively. The voltage-changing part is controlled by a second gate signal applied from the second gate line. The voltage-changing part increases a voltage level of the domain-dividing electrode and decreases a voltage level of the second pixel part.

  • Publication number: 20080137528
    Abstract: Embodiments of the invention can resolve conflicts between candidate master network devices such as may be encountered in a failover condition. In a common type of failover protocol, two or more candidate master devices send messages to each other prior to a failover condition. A witness device (or process or service) also casts a vote to prevent a stalemate condition between the two candidate master devices that could lead to an error condition where multiple masters, or no masters, are elected.

  • Publication number: 20070299942
    Abstract: In one embodiment, a first network node in a subnet retrieves a network configuration from a second network node located outside the subnet. The first network node communicates with at least one other network node to collect information from inter-node communication packets containing network address information other than an address assignment to the first network node. The first network node determines an available network address based on the network address information contained in the collected inter-node communication packets. The first network node is assigned the available network address and locates a network address for at least one subnet router. The network node accesses the second network node located outside the subnet, using the located network address for the at least one subnet router, for an available network configuration from a list of network configurations. The first network node is assigned the available network configuration.

  • Publication number: 20070266125
    Abstract: In one embodiment, a subnet mask is automatically determined by a first network node attached to a subnet in a packet communication network. The first network node issues plural communication packets from plural source addresses to at least one address known to be used in the subnet to evoke responses, and based on the presence or absence of responses from the network nodes at the known addresses, the first network node determines the subnet mask which represents the subnet.

  • Patent number: 7281036
    Abstract: The present invention includes a method and apparatus for automatically assigning a network address to a network device in an electronic communications network carrying inter-device communication packets to and from electronic devices located at assigned network addresses. The network device, also referred to as an appliance, communicates with at least one other network device to collect information from inter-device communication packets, which contain network address assignment information. From the network address assignment information in the communication packets, the appliance determines an available network address. The appliance assumes the available network address. The appliance may access a remote network device to retrieve an available, permanent, network configuration, including IP address.

  • Publication number: 20070115234
    Abstract: In a display apparatus, a first display substrate includes a common electrode to which a common voltage is applied. A second display substrate facing the first display substrate includes a first pixel electrode and a second pixel electrode. The first and second pixel electrodes formed in one pixel region are spaced apart from and insulated from each other. A first data voltage having a first polarity with reference to the common voltage is applied to the first pixel electrode, and a second data voltage having a second polarity different from the first polarity with reference to the common voltage is applied to the second pixel electrode. Thus, a fringe field is formed between the first and second display substrates and a lateral field is formed in the second display substrate, thereby improving a transmittance and a response speed of the display apparatus.
