    • This invention relates to a readily portable apparatus and the related method of determining the useful torque and horsepower wherein the apparatus includes a first unit which provides a velocity signal directly proportional to the velocity of rotation of the prime mover and has as an output a signal indicative of the velocity of rotation of the prime mover. A second unit is coupled to the first unit to provide a signal directly proportional to acceleration. A third unit is coupled to the first and the second units, respectively, and provides an output which is directly proportional to the useful horsepower and torque developed at any given instant during operation of the prime mover.
    • 本发明涉及易于携带的装置和确定有用转矩和马力的相关方法,其中装置包括第一单元,该第一单元提供与原动机的旋转速度直接成比例的速度信号,并具有作为输出的信号指示 的原动机的旋转速度。 第二单元耦合到第一单元以提供与加速度成正比的信号。 第三单元分别联接到第一和第二单元,并且提供与在原动机操作期间的任何给定时刻产生的有用马力和转矩成正比的输出。
