Patent ID: 8378841

Claim:
A trackable pipe comprising: a) a hollow pipe comprising a wall portion having an outer surface; b) a low frequency radio frequency identification (RFID) tag attached to said hollow pipe at said outer surface, said RFID tag being operable at a low radio frequency not exceeding 1.0 megahertz, said RFID tag comprising: i) a tag transceiver operable to transmit and receive data signals at said low radio frequency not exceeding 1.0 megahertz; ii) a tag communication antenna operatively connected to the tag transceiver; iii) a tag data storage device operable to store data comprising identification data for identifying said object; iv) a tag data processor operable to process data received from said tag transceiver and said tag data storage device and to send data to cause said tag transceiver to emit an identification signal based upon said identification data stored in said tag data storage device; and v) a tag energy source for activating said tag transceiver and said tag data processor, wherein said energy source comprises an electrical energy storage device and an electrical generator operable to energize the aforesaid electrical storage device, and said electrical generator comprises a tag power antenna operable to pick up energy induced by an applied varying external electric field, and wherein said tag communication antenna comprises a first elongated ferrite core, said tag power antenna comprising a second elongated ferrite core, oriented substantially orthogonally to said first elongated ferrite core and energy storage device is connected to said tag power antenna.
