    • An improved gas-electric power delivery system is provided. The invention provides an array of internal combustion engine-powered electric generators and an array of electric drive motors wherein each electric drive motor connects to a common shaft. The common shaft of the electric drive motor array connects to a mechanical load of varying power demand. The electric drive motors draw power from a battery in response to demands on the motors by the varying power demands of the external load. The array of electric generators charges the battery and each such generator turns on and off, as needed, to maintain the battery charge in response to demands on the battery by the electric drive motor array. Each electric motor connected to a common shaft in the electric motor array also turns on and off, as needed, to meet the varying power demands of the external load.
    • 提供了一种改进的气体电力输送系统。 本发明提供了一种内燃发动机动力发电机阵列和电驱动马达阵列,其中每个电驱动马达连接到公共轴。 电驱动电机阵列的公共轴连接到不同功率需求的机械负载。 电驱动电机根据外部负载的不同功率需求响应电机的要求,从电池中吸取电力。 发电机组对电池充电,并且根据需要每个这样的发电机接通和关断,以通过电驱动电动机阵列来响应对电池的需求来维持电池充电。 根据需要,连接到电动机阵列中的公共轴的每个电动机也根据需要打开和关闭,以满足外部负载的变化的功率需求。

    • A balance circuit for an amplifier circuit having 2.sup.M amplifiers serially biased across a supply potential node and a common potential node, where M is an integer greater than 0, and having respective 2.sup.M -1 interstage bias nodes and voltages between the amplifiers which are driven by respective input drive signals provided by 2.sup.M -1 2-way power splitters. A voltage reference circuit provides as to each power splitter first and second reference potentials respectively associated therewith. A plurality of control circuits are associated with respective power splitters and interstage nodes. Each control circuit is responsive to the associated first and second reference potentials and the interstage bias node for controlling the signal levels of the first and second drive signals provided by the associated 2-way splitter as a function of the associated interstage bias potential relative to the first and second reference potentials.
