  • Publication number: 20060205417
    Abstract: Methods and apparatus are provided for estimating a location of a plurality of wireless terminals. Signal strength measurements are obtained for at least one packet transmitted by each of the wireless terminals; and a Bayesian algorithm is applied to the signal strength measurements to estimate the location of each wireless terminal. In an infrastructure-based deployment, signal strength measurements are obtained from one or more signal monitors. In a client-based model, signal strength measurements are obtained from a client associated with a respective wireless terminal.

  • Publication number: 20050176442
    Abstract: A system is disclosed that enables the estimation of the location of a wireless terminal in a wireless network. The illustrative embodiment works without requiring modifications to be made to the wireless terminal. Furthermore, the hardware of some embodiments of the present invention can be inexpensively deployed indoors. Some embodiments of the present invention are, therefore, ideally suited for use with legacy indoor systems. The system of the illustrative embodiment of the present invention, in some embodiments, uses an offline process and an online process for location estimation. The described system, however, can be used with other techniques for location estimation.

  • Patent number: 6707903
    Abstract: An automated method for servicing a plurality of work items within committed times. A workflow including two or more work activities is assigned for each of the plurality of work items and a commitment is assigned either to each workflow or to each work item in each workflow. Queued work items are automatically assigned to a next available agent based on an activity state. A short-term predictor provides early detection of work items that are at risk of failing to meet their commitments. A long-term predictor detects backlogs of work items where excessive delays in queue are likely to put work items at risk of failing to meet their commitments. An activity's state can also cause additional reserve and backup agents to be assigned to it, to service work items from its queue before their commitments are missed.
