Abstract: A radio frequency identification device includes an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.

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.

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.

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.

Abstract: A method, a system, and an apparatus are provided for wireless communication of a traffic signal over a network. A message comprising data related to the traffic signal is received. Thereafter, the forwardability of the message is detemined. If forwardable, the message is forwarded. The validity of the message is checked and if found to be valid, information in the data is communicated to a vehicle controller. The message is discarded, if it is found to be invalid.

Abstract: A method, system and apparatus are provided for securely connecting a peripheral device to a processing device in a wireless network. The peripheral device makes a request for access to the processing device, which generates a challenge message and prompts a user to respond. The peripheral device is allowed access to the processing device, based on the user's response. If the user's response validates the challenge message, access is allowed; otherwise it is disallowed.

Abstract: A method, system, apparatus and machine-readable medium for monitoring a server in a network is provided. Based on a predefined condition, at least one reference value of the server is updated, the reference value being determined from a reference Uniform Resource Locator (URL). Subsequently, a test URL of the server is used to determine a test value of the server. The state of the server is determined, based on a comparison between the test value and the reference value.

Abstract: The various embodiments of the invention provide a method, system, apparatus and machine-readable medium for transfer of data in a wireless network. The method involves identification of nodes through which the data can be transferred. The method further involves monitoring of parameters associated with a battery in the node. In addition, the methodit involves selection of a node among the identified nodes. Further, the method further involves transfer of the data through the selected node.

Abstract: The invention is directed to techniques for managing a network of nodes by automatically configuring the arrangement of nodes in the network. A network manager in a node selects a group of nodes and compares network metrics for each node in the group, such as a bottleneck bandwidth measurement from each node to a root node of the network. The network manager selects a target node using the network metrics. Optionally, the network manager can select a new group of nodes using the target node, compare network metrics for the new group, and optionally select a new target node. If the node is a newly connecting node to the network, the network manager can repeat this process of selecting new groups until establishing a relationship with a target node that is not a root node (e.g., with performance that is the same, or about the same, as the root node), because the goal is not to overload the root node with too many relationships.

Abstract: The invention relates to a telephone conference system and an associated method. A conference phone includes a plurality of input audio signals and a spatial preference sensor adapted to identify a listening preference associated with at least one conference participant. The spatial preference sensor might indicate a head position of a conference participant, such that small movements of the participant's head control processing of a plurality of input signals resulting in a more audibly intelligible conference.

Abstract: The invention is directed to techniques for managing data distribution in a network. A source or root node distributes data (e.g., video data) throughout a network of nodes by distributing data from parent to child through a tree of nodes. The nodes distribute the data through the network concurrently in a real-time manner, but retain copies of the data in nonvolatile data storage on each node. Thus, the data remains accessible on each node so that the data is available after the real-time distribution of the data. After the real-time distribution of the data, a new node can attach to any of the nodes currently in the network as a child of that node, and then the new node can request a copy of the data from the data storage of that parent node.

Abstract: A method, system and apparatus are provided for dynamically pre-positioning content from servers located in a network, which may be a content distribution network. The content is pre-positioned on a proxy server, and the pre-positioning is triggered by at least one of the scheduling of an event and the presence of a user. Users commuting between different locations of a company can quickly and easily access the pre-positioned content. This content may be prioritized and pre-positioned, based on a user requiring a specific content at a particular time.

Abstract: The invention is directed to techniques for maintaining a map of node relationships for a network of nodes (e.g., network of computers). In one example, the map of node relationships represents relationships overlaying and typically different from the network of physical connections among the nodes. Each child node periodically checks in with its parent nodes, and the parent nodes can thus determine when a child node has terminated a relationship with the parent or created a new relationship with a new parent. Changes in relationships propagate upward through the network of nodes so that each node maintains a map of the relationships among the descendants of that node. A root node receives the propagated change relationship information and maintains a map of the entire network and valid pathways through the network.
