    • A wheel servicing machine such as a wheel balancer includes an acoustic transducer configured to measure energy of one or more reflected acoustic waves after the waves have bounced off a material boundary surface such as a wheel assembly. In some embodiments, a return energy index signal representative of the measured energy is generated by a transducer and is further processed by a processor to control operations of the machine. The acoustic transducer also measures distance between the transducer and the wheel assembly surface in some embodiments. One or more values in a sample queue of acquired distance data may be flagged, or indexed, based on variation in the magnitude of the return energy signal. Methods of measuring wheel width using sonar measurement of both distance and reflected energy are also provided.
    • 诸如车轮平衡器之类的车轮维修机器包括声波换能器,该声学换能器被配置为在波浪从材料边界表面(例如车轮组件)弹起之后测量一个或多个反射声波的能量。 在一些实施例中,表示测量能量的返回能量指数信号由换能器产生,并由处理器进一步处理以控制机器的操作。 在一些实施例中,声换能器还测量换能器和车轮组件表面之间的距离。 所获取的距离数据的采样队列中的一个或多个值可以基于返回能量信号的大小的变化被标记或索引。 还提供了使用距离和反射能量的声纳测量来测量车轮宽度的方法。
