发明名称 Universal send/receive utility usage data gathering system
摘要 A utility usage data gathering system that is universally capable of operating with any other portion of another usage gathering system is disclosed. The system comprises of major portions, the universal transponder or actual device that accumulates utility usage and will universally relay accumulated usage to any reader/interrogator, and the universal reader that will universally read its own transponder or any other transponder. The system is based on standard micro-electronic chips and uses the same chips and logic in both the reader/interrogator and transponder. Each portion of the system, when polled by a foreign device, will determine what communication protocol is required and will respond to collect or transmit utility usage data in the proper protocol. Both portions of the apparatus use switchable multi-tapped antennae, capable of universal matching in order to transceive the modulated electromagnetic wave which contains the utility usage data.
