    Summarizes important developments relating to power for deep space missions. The important alternatives to thermocouples for converting radioisotope heat into electric power are Stirling engines, alkali-metal thermal-to-electric converters (AMTEC), thermionic converters, and thermo-photovoltaic converters. The operating principles and limitations of these converters are described. View full abstract»

    An ultracapacitor system for an electric vehicle has been implemented. The device allows higher accelerations and decelerations of the vehicle with minimal loss of energy and minimal degradation of the main battery pack. The system uses a DC-DC power converter, which is connected between the ultracapacitor and the main battery pack. The design has been optimized in weight and size, by using water-...

    The first monostatic microwave intrusion detection sensor with range cutoff was introduced in 1984. This range cutoff circuit as used in the Model 375 and 385 has proven very effective in preventing nuisance alarms beyond a user-defined range. The Intrepid Digital Transceiver introduced in this paper builds upon this proven technology with the addition of a unique digital signal processing routine... View full abstract»

    New battery applications ranged from an implanted battery that powers an artificial heart, to powering a seismic sensor behind an oil-well drilling bit as it grinds through rock looking for oil-bearing structure. These applications require high reliability that justifies the cost of thorough qualification testing, production control, acceptance testing of every cell, and tracking every cell by its...
