    摘要： Apparatus and methods are disclosed for determining internal engine characteristics using acoustic-vibration data. Exemplary such data are passive acoustic pyrometer data. Acoustic-vibrational frequencies emanating from a running engine are detected and compared to frequencies having known relationships to particular operating characteristics of the engine. In an example, the dominant frequency or other prominent frequency emanating from an internal-combustion chamber of a turbine engine is detected and used to determine the fuel-to-air ratio in the chamber. The determined data are used for performing adjustments or optimizations of engine performance, such as adjusting the fuel-to-air ratio as required or desired. In a similar manner, operating characteristics of other engines or engine-like environments, including furnaces and boilers, can be determined.

    摘要： The present invention includes an apparatus and method for cutting a bone including a cutting assembly having a cutting blade, a cutting guide for guiding the shape of the cut in the bone, and a power source for powering the cutting blade. The cutting blade is moveable radially to vary the depth of the cut in the bone, and the cutting blade is capable of cutting around the circumference of the bone as well as in a longitudinal direction along the bone. A powered bone breaking device for completing the breaking of the weakened bone is also disclosed. A miniaturized version of the bone cutting apparatus can be used to cut out sections of a femur head from inside a femur body.
