Abstract: An enclosure and mounting system that provide ideal RF signal transmission and battery management for AMR systems utilized with a utility meter in a utility meter pit environment are disclosed. The AMR device includes processing electronics that receive consumption data from a pit-mounted utility meter, an antenna to wirelessly transmit signals from the AMR device, and an enclosure that houses the processing electronics and the antenna to provide protection thereto. The enclosure is configured to support different battery sizes and provide battery wire/connector management. The enclosure also defines a dome-shaped antenna compartment therein to house the antenna, the antenna compartment protruding out from a remainder of the enclosure so as to provide for positioning of the antenna at a location extended out therefrom. A companion adaptor utilized with the AMR device is mountable to a cover of the utility meter pit and increases a height of the antenna relative thereto.

Abstract: A surrogate temperature sensor (52) for a convection cooled radiant heater system is described. The surrogate temperature sensor has an internal controllable heater (62) and a sensing device such as a thermocouple (64). The surrogate temperature sensor is paired with a furnace/dryer radiant heat source (38). The surrogate's internal heater provides sufficient power to heat the surrogate to the same temperature as the radiant heater. At least one surrogate temperature sensor (52) is positioned to be exposed to the cooling media in a manner similar to the radiant heat source. The surrogate sensor reports its temperature which is indicative of the radiant heater temperature to the cooling controller. The controller responds to this signal and adjusts cooling to maintain the radiant heater at its desired temperature.

Abstract: A two-stroke internal combustion engine (30) is disclosed. Fuel efficiency is improved and extended over a wide power band by an inlet air valve (108) which controls the air charge and maintains a constant compression ratio. An integrated positive displacement supercharger (50) provides adequate air charge at all power levels and recovers compressor power from unused supercharged air. An integrated post combustion chamber (48) extends the power stroke by mixing combustion gases with ambient air for farther expansion and power production. Exhaust noise is reduced because the combustion gases are vented from the engine at lower pressure, lower velocity and temperature. The opposed cylinder design provides nearly continuous power by combining supercharger power recovery with extended power strokes.
