Embodiment Construction

[0045] Unless specifically stated otherwise, the following express, it is worth noting that throughout the present invention, disclosed terms such as "send", "compute", "determine", "broadcast", "generate", "retrieve" , "output", or similar names, refers to a computer system or similar electronic equipment that manipulates and converts data expressed as physical quantities in a computer system to other similarly expressed data in a computer system or other information storage, transmission or display equipment action and process.

[0046] figure 1 A block diagram showing the framework of a system 100 for searching for physical objects. System 100 includes tag 102 , substation 104 and base station 106 . Tags 102, substations 104 and base stations 106 are embedded at the time of object manufacture. Alternatively, tags 102, outstations 104 and base stations 106 may be placed on objects by a user of system 100. For example, by employing a printable antenna, it is easy to write...

Abstract

A system and method for searching physical objects. The system comprises one or more tags, each tag being disposed on one associated object; one or more substations, each substation arranged for communication with tags located within a range around each substation; one or more base stations, each base station arranged for communication with substations located within a range around each base station; an interrogation engine residing in each base station for interrogating, in response to a search query, the substations within the range around each base station, to determine whether a search object of the search query is within the range around the respective substations.

Description

technical field [0001] The present invention relates to a system and method for searching physical objects. Background technique [0002] As information and communication technology advances, query engines are so efficient at generating information in the form of search queries that there is no need to download and store data locally. Hence, searching for information on the internet is an easy task nowadays. [0003] And, with no unnecessary loss of efficiency, less time and less effort is required in planning and organizing. For example, Google's Gmail enables mail to be tagged and searched efficiently. People can now stop compiling and filing their e-mails. [0004] However, searching for physical objects is still a tedious and difficult job. It takes a lot of time and effort to find specific objects or organize physical objects so that they can be easily retrieved in the future. [0005] Therefore, there is a need for systems and methods for searching for physical ob...
