Abstract: A method of operating a locomotive including a set of electrical traction motors, a fuel cell power module for generating electrical current for the traction motors, an air system for providing an air mass to the fuel cell power module, and a cooling system for cooling the fuel cell power module. When an amount of power is requested from the power module, a required current and a stoic set point for the power module are determined. From the required current, the stoic set point, and numerical factors characterizing the power module, an air mass flow set point is determined for producing the requested amount of power. A compressor set point including speed and torque set points of a compressor motor are determined for the air system to produce the air mass flow corresponding to the requested amount of power.

Abstract: Improved heaters and self-heating packages that function without application of external energy. Heat is generated by contact of a heat-producing composition, such as calcium oxide, and an activating solution which is typically water. The heater contains multi-compartments containing heat-producing composition and activating solution. The heater is activated by application of hand pressure to rupture a frangible seal which allows the heater components to mix. The heater compartments are at least in part formed from flexible walls. The self-heating package has one or more products or product containers in thermal contact with one or more heaters. In preferred packaging embodiments, the heating package has one or more product containers or pouches in thermal contact with one or more heaters. In a specific embodiment, the product container is integrally formed with the heater. Preferred self-heating packages are constructed entirely of flexible packaging materials.

Abstract: A portable heat source that may be used to warm food, beverage or other supplies. The heater contains a heat-producing composition that is a solid that may be stored for long periods of time, and activated by addition of water or an aqueous solution. Heat-producing compositions contain an acidic anhydride, an acidic salt, a basic anhydride or a basic salt. Preferred heat-producing compositions contain a mixture of an acidic anhydride or salt together with a basic anhydride or salt, such that addition of water to both acidic and basic anhydrides produces heat as well as acid and base respectively; subsequent reaction of the acid and base produces additional heat, as well as a safe, neutral product that is easily disposed. The invention further consists of means and methods for regulating the rate of heat production in heaters by the addition of inert additives to heat-producing compositions and the application of processing methods that regulate access of water to heat-producing compounds.
