An antenna includes an elongate dielectric strip having opposing first and second sides. A first conductive pattern defines a first radiating element for a first frequency range on the first side of the elongate dielectric strip. A second conductive pattern defines a second radiating element for a second frequency range on the first side of the elongate dielectric strip. The second frequency range is different than the first frequency range. A diplexer circuit is on the elongate dielectric strip between said first and second radiating elements and coupled thereto. A third conductive pattern defines a shared ground plane for the first and second radiating elements on the second side of the elongate dielectric strip.

Antenna for wearable radio system and associated method of making

A method is provided for operating a heater including a heater housing extending along a heater axis; a plurality of fuel cell stack assemblies disposed within the heater housing along the heater axis and having a plurality of fuel cells which convert chemical energy from a fuel cell fuel into heat and electricity through a chemical reaction with a fuel cell oxidizing agent; and a plurality of combustors disposed within the heater housing along the heater axis. The method includes supplying a combustor fuel to the plurality of combustors, combusting the combustor fuel to produce a heated combustor exhaust when the fuel cell stack assemblies are substantially electrochemically inactive, and using the heated combustor exhaust to elevate the temperature of the fuel cell stack assemblies to be electrochemically active.

Method of operating a heater

A geothermic heater system for heating a geological formation includes a fuel cell stack assembly disposed at the surface of the geological formation and includes a plurality of fuel cells which convert chemical energy from a fuel into electricity through a chemical reaction with an oxidizing agent, thereby producing an anode exhaust and a cathode exhaust. The geothermic fuel cell system also includes a combustor disposed within a bore hole of the geological formation. The combustor combusts a mixture at least one of the anode exhaust and the cathode exhaust to produce a heated combustor exhaust. The combustor discharges the heated combustor exhaust to heat the geological formation.

Geothermic heater system

A heater includes a heater housing extending along a heater axis. A fuel cell stack assembly is disposed within the heater housing and includes a plurality of fuel cells which convert chemical energy from a fuel cell fuel into heat and electricity through a chemical reaction with a fuel cell oxidizing agent. A combustor disposed within the heater housing includes a combustor fuel inlet for introducing the combustor fuel into the combustor, a combustor oxidizing agent inlet for introducing a combustor oxidizing agent into the combustor, and combustor exhaust outlet for discharging a heated combustor exhaust from the combustor. An anode exhaust conduit is connected to the anode exhaust outlet and extends out of the heater housing for selectively communicating a first quantity of the anode exhaust out of the heater housing. The heater housing is heated by the fuel cell stack assembly and the heated combustor exhaust.

Heater with a fuel cell stack assembly and a combustor and method of operating

A plurality of heaters are disposed end to end within a bore hole of a formation where the bore hole extends from an upper end to a lower end such that a lower heater of the plurality of heaters is proximal to the lower end of the bore hole while every other of the plurality of heaters is distal from the lower end of the bore hole. Each of the plurality of heaters includes a fuel cell stack assembly having a plurality of fuel cells which convert chemical energy from a fuel into heat and electricity through a chemical reaction with an oxidizing agent. Each of the plurality of heaters has a thermal output that is less than or equal to a predetermined value except the lower heater of the plurality of heaters which has a thermal output that is greater than the predetermined value.
