Abstract

The invention relates to an enclosure for housing transmitter components of an Automatic Meter Reading (AMR) system electrically associated with a utility meter disposed in a substantially non-RF transparent location. The enclosure comprises a first section mechanically associated with a second section where the first section is disposed outside the non-RF transparent location, and said second section extends from said first section to a point within said non-RF transparent location. The first section may house an antenna and a transmitter while the second section may house a power source electrically associated with said transmitter.

Claims

1. An apparatus for housing components of an AMR system associated with a utility meter, wherein said utility meter is located inside a substantially non RF transparent environment, said substantially non RF transparent environment comprises at least one access-surface defining an access-hole there through, said apparatus comprising:

a top-section comprising a top-section-upper-piece associated with a top-section-lower-piece so that said top-section-upper-piece is substantially adjacent to said top-section-lower-piece thereby forming a top-section-void there between, said top-section-void suitably sized for receiving a transmitter and a corresponding antenna;

a depending base having a first end and a second end wherein said first end is associated with said top-section-lower-piece and extend to a point distal to the said top-section-lower-piece; and

wherein said top-section is suitably configured for being associated with said access-surface so that said top-section-lower-piece is substantially adjacent to said access-hole so that said depending base extends from said top-section, through said access-surface and to a point at least partly through the access-surface.

2. An apparatus for housing components of an AMR system as in claim 1, wherein said top-section-lower-piece and said depending base are a single piece.

3. An apparatus for housing components of an AMR system as in claim 1, wherein said depending base is configured to house a power source electrically associated with said transmitter.

4. An apparatus for housing components of an AMR system as in claim 1, wherein said depending base further comprises an energy-converter compartment for housing an energy-converter.

5. An apparatus for housing components of an AMR system as in claim 4, wherein said energy-converter compartment forms a shell for housing a radioactive gas and wherein substantially all of the inside surface of said energy-converter compartment is lined with a plurality of PN junctions.

6. An apparatus for housing components of an AMR system as in claim 5, wherein the surface of said PN junctions define a plurality of indentions about 1μ

wide, 1μ

long, and 40 μ

m deep.

7. An apparatus for housing components of an AMR system associated with a utility meter, wherein said utility meter is installed in an underground pit enclosure associated with a pit lid that is generally at ground level, said pit lid defining an opening there through, said apparatus comprising:

a depending base comprising a first end and a second end;

a top-section mechanically associated with said first end, wherein said top-section is suitably configured to rest generally on top of said pit lid and substantially co-planer with said pit lid so that said second end is located at least partly through the opening in said pit lid; and

wherein said top-section is suitably configured to receive a transmitter and a corresponding antenna so that said transmitter and antenna are positioned outside said pit enclosure.

8. An apparatus for housing components of an AMR system as in claim 7, further comprising at least one photovoltaic cell disposed on an outer surface of said top-section in a location that does not substantially block the RF transmission path of said antenna.

9. An apparatus for housing components of an AMR system as in claim 7, wherein said depending base extends completely through said pit lid to a point inside the pit enclosure and wherein said depending base is configured for housing a first-power-source.

10. An apparatus for housing components of an AMR system as in claim 9, wherein said depending base further comprises an auxiliary power connector suitably configured for at least one of (a) connecting additional power sources to said transmitter and (b) disconnecting said first-power-source.

11. An apparatus for housing components of an AMR system as in claim 10, where said top-section and said depending base are suitably configured to receive a sealing material for encasing substantially all of the top-section and depending base.

12. An apparatus for housing components of an AMR system associated with a utility meter, wherein said utility meter is installed in a substantially non RF transparent enclosure associated with at least one access lid, said access lid defining an opening there through, said apparatus comprising:

a top-section mechanically associated with a depending base, said top-section defining a void suitably sized for receiving a transmitter and a corresponding antenna, wherein said top-section is suitably configured to rest generally adjacent to an access lid and substantially co-planer with said access lid so that said depending base extends from said top-section to a point at least partly through an opening in said access lid; and

wherein said top section comprises an RF transparent section providing propagation path for RF signals generated by said transmitter and antenna.

13. An apparatus for housing components of an AMR system as in claim 12, wherein said antenna is disposed substantially adjacent to said RF transparent section and is suitably configured for being electrically associated with said transmitter.

14. An apparatus for housing components of an AMR system as in claim 13, wherein said depending base is configured for housing a power source.

15. An apparatus for housing components of an AMR system as in claim 14, further comprising at least one photovoltaic cell disposed on an outer surface of said top-section in a location that does not substantially block the RF transmission path provided by said RF transparent section and wherein said at least one photovoltaic cell is electrically associated with said power source.

16. An apparatus for housing components of an AMR system as in claim 14, where said top-section and said depending base are suitably configured to receive a sealing material for encasing substantially all of the top-section and depending base in a protective material.

17. An apparatus for housing components of an AMR system as in claim 16, wherein said depending base further comprises an auxiliary power connector suitably configured for at least one of (a) connecting additional power sources to said transmitter and (b) disconnecting said first-power-source.

18. An apparatus for housing components of an AMR system as in claim 12, wherein said top-section further comprises a section for receiving one of a core and a coil.
