Abstract:
1. A method of managing progress of at least two parties engaged in converging upon a predetermined common destination at substantially the same time, comprising the steps of: providing each party with a portable location reporting device having a location capability wherein the portable location reporting device is capable of determining location, and a communication capability wherein the portable location reporting device is capable of receiving location information from the other portable location reporting devices and of transmitting location information to the other portable location reporting devices; monitoring location of at least two of the parties by querying each one of the monitored parties using one of the portable location reporting devices; estimating arrival time of the parties who were monitored; and determining a common destination which will be reached at substantially the same time by all of the parties, based on estimated arrival times of the parties; calculating magnitude of separation for each one of the monitored parties; adjusting the time intervals at which the location of each one of the monitored parties is queried based on calculated magnitudes of separation of the monitored parties; and reducing time intervals between queries as the estimated time until arrival decreases.
