  • Publication number: 20070286205
    Abstract: In embodiments of the present invention improved capabilities are described for sensing a change in a network topology using a discovery node in a mesh network; transmitting an explore frame, based at least in part on the sensed change, from the discovery node to a destination node using an intermediate node; receiving a response to the explore frame from the destination node; determining at least one functional network route from the discovery node to the destination node based at least in part on route information received in association with the response to the explore frame, wherein the route information includes a node path; and transmitting an instruction to the destination node from the discovery node based on a reverse node path.

  • Publication number: 20070263647
    Abstract: In embodiments of the present invention improved capabilities are described for configuring a constant powered mesh network node to control the configuration of an intermittently powered mesh network node, wherein the intermittently powered mesh network node periodically powers down to conserve energy; and causing the intermittently powered mesh network node to request configuration information from the constant powered mesh network node when the intermittently powered mesh network node powers up. In embodiments of the present invention improved capabilities are described for scanning a plurality of nodes in a mesh network to identify a current active wake up destination for a battery powered mesh network node; requesting the current active wake up destination to send a change wakeup destination signal; and requesting a new route from a node in the mesh network if the battery powered mesh network node does not have a wakeup destination in its memory.

  • Publication number: 20070224654
    Abstract: The invention relates to a method of evaluating the immunological status of a subject comprising the steps of 1) determining the content of an antibody in a liquid sample from the subject using an immunoassay, wherein the reaction between the antibody of the sample and a ligand in the form of an antigen, an antibody or a hapten, the ligand being directed to the Fab region of the sample antibody, is carried out in the presence of other constituents of the sample to obtain a measurement 1, 2) determining the content of an antibody in the liquid sample using an immunoassay, wherein the reaction between the antibody of the sample and a ligand in the form of an antigen, an antibody or a hapten, the ligand being directed to the Fab region of the sample antibody, is carried out in the absence of other constituents of the sample to obtain a measurement 2, and 3) interrelating measurements 1 and 2 to express the interference and using the interference as a parameter for evaluating the immunological status of the

  • Publication number: 20070201504
    Abstract: In embodiments of the present invention improved capabilities are described for using a node in a mesh network to perceive a plurality of channels within a mesh network; selecting a first channel from the plurality of channels within the mesh network with the node; remaining on the first channel with the node for a predefined duration; remaining on the first channel beyond the predefined duration in order to receive a message if a signal is detected during the predefine duration; and selecting a second channel with the node once the predefined duration has elapsed without the signal detected.

  • Patent number: 6087188
    Abstract: A method of detecting an antibody in a sample using a labelling compound and comprising the steps of mixing a ligand antigen, antibody or hapten bound to biotin with the sample; an antibody directed against the antibody to be detected bound to paramagnetic particles; and a chemiluminescent acridinium compound bound to avidin or streptavidin to form a solid phase complex; separating the solid phase from the liquid phase; and analyzing the separated solid phase for the presence of chemiluminescent complex.
