Abstract: An electronic control for a locomotive airbrake featuring field replaceable control portions having a minimum of pneumatic and electrical connections which are controlled by a redundant, distributed network of microprocessors.

Abstract: Lithium polymer battery charger methods for charging a plurality of equal charge point lithium polymer battery cells prevent overcharging of any cell, whether the cells are arranged in a series stack or are arranged in parallel. When the cells are connected in a series stack, a power supply is connected to the series stack to apply a charge current to the series stack. The state of charge of each cell in the stack is monitored. Information that the state of charge of any cell is approaching full charge is used to control the charge current and to prevent overcharging of any cell.

Abstract: In a reactive metal-water electrochemical cell, an alkaline electrolyte containing soluble inorganic ions which are reduced preferentially to water at the cathode. More particularly, the additives substantially reduce or eliminate reduction of water and evolution of hydrogen at the cathode resulting in significant improvement in current efficiency, gravimetric energy density and cell potential at a given current. Additionally, suppression of hydrogen evolution makes possible a sealed system with venting of gases from the cell no longer necessary. The inorganic ions of the invention are nitrite, hypochlorite, chlorate, bromate, dinitrogen trioxide and sulfite ions which are formed when soluble salts of nitrite, sulfite, hypochlorate, bromate, chlorate, soluble gases such as dinitrogen trioxide and sulfur dioxide and other soluble inorganic compounds are dissolved in the alkaline electrolyte.
