Abstract: A protective-fire-hydrant-cover comprising an operating-nut-extender and a protective-fire-hydrant-casing. The operating-nut-extender is firmly coupled with an operating-nut of a fire-hydrant such that when the operating-nut-extender rotates, the operating-nut rotates therewith, the operating-nut-extender includes an inner-groove exhibiting a substantially circular shape. The protective-fire-hydrant casing includes a lock-mechanism therein, which includes a latch. The latch moves between at least a locked and un-operable position and an unlocked position. The protective-fire-hydrant-casing fits over the operating-nut-extender such that it covers the operating-nut-extender and the latch aligns with the groove. When the latch moves to locked and un-operable position the latch enters the inner-groove thus internally locking the protective fire-hydrant-casing with the operating-nut-extender thus locking the protective fire-hydrant-cover onto the fire-hydrant.

Abstract: A method and system by which certain radio transmitters are assigned to certain reception nodes for the purpose of transmitting metering data derived from a plurality of utility meters to a system management computer. The reception nodes are configured to receive and process data transmissions only from those transmitters with data paths assigned to particular reception nodes, and to ignore data transmissions from non-listed transmitters, thereby assuring that on a continuous basis, a majority of the transmitters will utilize only one data path. Lists may be formed for the transmitters and reception nodes in the system management computer and transmitted to the reception nodes. The status of data transmissions through the repeaters may also be uploaded to the system management computer for analysis of data update rates and data path redundancy.
