作者提出了一种测量装置，由多个平行使用的超声波传感器组成，以执行三角测量。传感器系统基于两个思想。第一个想法是使用借鉴现有雷达和声纳系统的信号处理技术。这允许精确地确定多个对象的位置。实时处理数据需要一个相当强大的处理系统。第二个想法是为每个传感器分配一个微处理器。为了支持在最终测量设置中使用多个传感器，转换器被用作处理元件，因为它们具有串行链路，因此易于扩展。该传感器测量到多个物体的距离非常准确，分辨率为2厘米。结果表明，这些技术可以以经济有效的方式实现
The authors propose a measurement setup consisting of a number of ultrasonic sensors used in parallel to perform triangulation measurements. The sensor system is based on two ideas. The first idea was to use signal processing techniques borrowed from existing radar and sonar systems. This allows the accurate determination of the position of multiple objects. Processing data in real time demands a fairly powerful processing system. The second idea was to assign a microprocessor to each transducer. To support the use of multiple sensors in the final measurement setup, transputers were used as processing elements as they offer easy scalability because of their serial links. This sensor measured the distance to multiple objects very accurately and with a resolution of 2 cm. It is shown that these techniques could be implemented in a cost-effective manner.<<ETX>>
