Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This application claims priority from U.S. application No. 60/805,020 filed Jun. 16, 2006, which application is incorporated herein by reference for all purposes. BACKGROUND [0002] Prior-art systems use RF tags that can be subjected to any Electromagnetic Interference (EMI) risk to hearing aid wearers, pacemakers, or IDC patients and had problems with Electromagnetic Compatibility worldwide. [0003] Prior-art systems always had bandwidth as an issue. Prior-art systems also had high cost, low client count, short battery life and can only function in mild environment (away from steel and water). Many cost-sensitive, power "limited" applications exist (e.g., most industrial visibility networks) that may not require bandwidth, yet do require real-time, peer-to-peer networking with extended battery life. [0004] The purpose for the below-described preferred embodiment to address above-listed problems within a long-wavelength network. SUMMARY [0005] The Visibility Network is designed to provide real-time web enabled asset visibility. The RuBee IV protocol was designed to work reliably in a local visibility network and provide real-time visibility for assets, people, and livestock, pedigree and provide chain of possession events. [0006] RuBee works over a controlled-range, wide area (1'.times.1' to 100'.times.100') in harsh environments (that is, near metals, liquids and through earth), with an extended battery life (10-15 years), and a high safety standard. The network's design goal was to create a low cost two-way radio tag that is safe for use in hospital patient-based settings, hospital operating rooms, airports and other public facilities. RuBee could not accept any Electromagnetic Interference (EMI) risk to hearing aid wearers, pacemaker, or IDC patients and has no known or Electromagnetic Compatibility (EMC) issues worldwide. Yet, RuBee provides range and the reliability needed to produce a real-time visibility network. Every radio tag attached to an asset appears to be a mini-web asset server within the Visibility Network. The Long Wavelength ID (LWID) tag has an antenna operable at a low radio frequency not exceeding 1 megahertz The tag also has a radiating transceiver operatively connected to said antenna, the transceiver operates to transmit and receive data at low radio frequency. The tag also has a programmed data processor to process data received from the transceiver. The data processor usually is a low cost 4-bit processor capable of encrypting and decrypting and complex functions associated with managing IP addresses. The tag associated with a first IP address. The tag has a volatile memory that stores said IP address. The transceiver emits an identification signal based upon said IP address stored in the volatile memory. The tag also has an energy source used for activating the transceiver and the data processor. Any RuBee IV tag if enabled properly may be searched and discovered on Google or the VAI "Dot-Tag" network. [0007] The local network of tags talks to a RuBee Router (Sidewinder). The Sidewinder manages the local tag net in real time in much the same way any WiFi router manages a TCP/IP network. The Sidewinder communicates by a VPN to a data server which manages a PostgresSQL database of virtual tags (the Dot-Tag Visibility Data Server). [0008] Long wavelength, produces little, if any energy dissipated in the form of an electrical field (E). Long wavelength transmissions radiate energy (99.99%) in the form of a magnetic field (H). The RuBee radio tags are inductive tags and typically need a minimum signal of 0.1 milligauss to a maximum of about 300 milligauss for reliable communication. The strongest field near or on top of a base station antenna can be about 1200 milligauss, however most standard antennas are in the 100-300 milligauss range. To help provide some context for these values, the earth's magnetic field is 300-600 milligauss. [0009] The systems are installed in several major retailers as in-store inventory visible systems, in hospitals to provide medical device visibility, other healthcare applications providing real time inventory visibility on high valued products throughout distribution, in agricultural applications providing visibility and age verification for cattle, and in other industries providing identity systems and visibility systems for patients, physicians, policemen, firemen, correctional officers and corporate employees. [0010] The advantage of this system low cost to clients, low cost base stations and routers, long battery life tags, high client/tag counts within a single network, and work in harsh environments (near steel and water).
