Patent Images
1. A pit mount interface device, comprising:
- a body having a head and an elongate stem extending from a bottom surface of the head, the elongate stem sized and configured to be received in and extend through a hole formed in a cover of a pit;
a nut defining a central aperture sized and configured to receive the elongate stem of the body, the nut for coupling the body to pit cover;
a passive radiator disposed within the body and configured to receive a radio frequency (RF) signal transmitted by an automatic meter reading (AMR) device located below the cover through inductive coupling and radiate the RF signal from a position located above the cover of the pit; and
a pair of spaced apart tabs extending from an interior surface of the elongate stem, the pair of spaced apart tabs sized and configured to slidably receive a conducting section of the passive radiator.

Abstract
A pit mount interface device includes a body having a head and an elongate stem extending from a bottom surface of the head. The elongate stem is sized and configured to be received in and extend through a hole formed in a cover of a pit. A nut defines a central aperture that is sized and configured to receive the elongate stem of the body. A passive radiator is disposed within the body and configured receive a radio frequency (RF) signal transmitted by an automatic meter reading (AMR) device located below the cover through inductive coupling and to radiate the RF signal from a position located above the cover of the pit.

7. A pit mount interface device, comprising:
-
a body having a head and an elongate stem extending from a bottom surface of the head, the elongate stem having a width that is smaller than a width of the head and including at least one thread disposed on an external surface; a nut defining a central aperture that is sized and configured to receive the elongate stem of the body, an interior surface of the nut including a thread configured to engage the thread disposed on the external surface of the elongate stem; a passive radiator disposed within a channel defined by the head of the body and configured to receive a radio frequency (RF) signal transmitted by an automatic meter reading (AMR) device disposed adjacent to a coupling section of the passive radiator through inductive coupling and to radiate the RF signal from a radiating section of the passive radiator positioned above a cover of a pit; a cap configured to be coupled to the head of the body such that the radiating section of the antenna is secured within a slot; and a pair of spaced apart tabs extending from an interior surface of the elongate stem, the pair of spaced apart tabs sized and configured to slidably receive a conducting section of the passive radiator. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of installing a pit mount interface device, comprising:
-
inserting a passive radiator into a mounting body having an elongate stem extending from a head, the elongate stem having a substantially circular cross-sectional area defining a central passageway, wherein inserting the passive radiator into the mounting body includes sliding edges of a conducting section of the passive radiator along a pair of spaced apart tabs that extend from an interior surface of the elongate stem until a radiating section of the passive radiator is received within a channel defined by the head of the mounting body; attaching a cap to the head of the mounting body to secure the passive radiator within the mounting body; inserting the elongate stem into a hole defined by a cover of a pit until a bottom surface of the head of the elongate body contacts a surface of the cover; and fastening a clamp nut to the elongate stem to secure the mounting body to the cover. - View Dependent Claims (15, 16, 17)

23. A method of installing a pit mount interface device, comprising:
inserting a passive radiator into a mounting body having an elongate stem extending from a head, the elongate stem having a substantially circular cross-sectional area defining a central passageway; attaching a cap to the head of the mounting body to secure the passive radiator within the mounting body; inserting the elongate stem into a hole defined by a cover of a pit until a bottom surface of the head of the elongate body contacts a surface of the cover; fastening a clamp nut to the elongate stem to secure the mounting body to the cover; aligning a pair of projections that extend from a neck of the AMR device with a pair of slots defined by an interior surface of the elongate stem; advancing the neck of the AMR device into the central passageway of the elongate stem; and rotating the AMR device such that the projections are received within a pair of openings defined by the elongate stem, each opening in communication with a respective one of the slots defined by the interior surface of the elongate stem. - View Dependent Claims (24, 25, 26)
