Abstract:
A PLAD (pervasive location aware device) communicating instrument, said instrument enabling a user thereof to coordinate implementation of a broad variety of services at multiple remote sites at which said user may conduct different business transactions, and wherein coordination of said services is based on varied relations of proximity of said PLAD instrument to said sites; said PLAD instrument comprising:means for communicating directly with individual ones of said sites; means cooperative with said communicating means for storing diverse program applications associated with services to be performed at said sites; each application enabling said PLAD to detect when it is within a variably determined range of proximity to a site associated with the application, determination of said range being set as a variable function by the respective application; and means responsive to detection that the respective PLAD instrument is within said variably determined range of proximity to a site associated with a said application for initiating proximity notification communications between said PLAD and said associated site; said communications serving to activate a process at said associated site to provide a service to the user of said instrument while said user is at a known distance from said site; efficient preparations of said service at said multiple sites involving lead time factors that are related to proximity ranges which are variably set by multiple applications associated with said sites; as a result of which said time factors can be different from each other at different said sites.
