Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences. Other embodiments are also described.

1. A system for radio frequency identification (RFID)-enabled information collection comprising: one or more ring elements, each ring element including a conductive ring connected to an RFID integrated circuit;at least one source element;an interrogator capable of transmitting a signal to the source
1. A system for radio frequency identification (RFID)-enabled information collection comprising: one or more ring elements, each ring element including a conductive ring connected to an RFID integrated circuit;at least one source element;an interrogator capable of transmitting a signal to the source element; andat least one of the conductive rings capable of coupling to its source element when the conductive ring is in a first position and orientation, energizing the RFID circuit associated with the conductive ring to respond; anda processor in communication with the interrogator and capable of deriving information regarding the positions and orientations of the one or ring elements relative to the one or more source elements. 2. The system of claim 1, wherein the source element comprises an antenna element. 3. The system of claim 1, wherein the source element comprises an open waveguide such that the ring element can couple to the waveguide structure when it is in the proper position and orientation. 4. The system of claim 1, wherein the conductive ring and the source element are placed on door components such that the conductive ring couples to the source element only when the door is in a first position. 5. The system of claim 1, wherein the conductive ring has a shape selected from group comprising circular, elliptical, triangular, rectangular, trapezoidal, and other polygonal. 6. An apparatus for radio frequency identification (RFID)-enabled information collection comprising: one or more ring elements, each ring element including a conductive ring connected to an RFID integrated circuit; andat least one source element, responsive to a signal from an interrogator and capable of transmitting a responding signal from the RFID integrated circuit when energized;wherein at least one of the conductive rings is capable of coupling to its corresponding source element when the conductive ring is in a first position and orientation, energizing the RFID circuit associated with the conductive ring to respond; andwherein the responding signal from the RFID integrated circuit is capable of being analyzed by a processor in communication with the interrogator, the responding signal containing information regarding the positions and orientations of the one or ring elements relative to the one or more source elements. 7. The system of claim 6, wherein the source element comprises an antenna element. 8. The system of claim 6, wherein the source element comprises an open waveguide such that the ring element can couple to the waveguide structure when it is in the proper position and orientation. 9. The system of claim 6, wherein the conductive ring and the source element are placed on door components such that the conductive ring couples to the source element only when the door is in a first position. 10. The system of claim 6, wherein the conductive ring has a shape selected from group comprising circular, elliptical, triangular, rectangular, trapezoidal, and other polygonal.
