    • A wave generator has a wave emitter including an elongated dispersive waveguide and a source operatively connected to a first end of the waveguide. The source covers at least partially a surface area thereof. A signal generator is in operative connection with the transducer to create electrical signals. A computer is in operative connection with the signal generator to cause it to generate the electrical signals. A mechanical input wave is created by the source at the first end of the waveguide. The mechanical input wave is constructed independently of data related to a mechanical wave received from a source in the medium and taking into account the different predetermined propagation velocities of at least two component waves of the mechanical input wave so that they combine with each other at a second end of the waveguide to form the desired mechanical output wave in the medium.

    • A sensor array for measuring various parameters in a machine environment, the sensor array comprising a number of oscillators, each of the oscillators comprising a feedback network, an amplifier and a limiter being connected together in a loop. The feedback network has a frequency which varies with the parameters to be measured. The amplifier consumes a current from a current supply and in cooperation with the feedback network produces a signal that alternates at the natural frequency of the feedback network. The limiter limits the amplitude of the signal within a predetermined amplitude range. All of the signals from the oscillators are multiplexed onto the output of the sensor array. Frequency analysis may then used to isolate the individual readings from each of the oscillators.
    • 一种用于测量机器环境中的各种参数的传感器阵列,所述传感器阵列包括多个振荡器,所述振荡器中的每一个包括反馈网络,放大器和在循环中连接在一起的限幅器。 反馈网络具有随测量参数而变化的频率。 放大器消耗来自电流源的电流,并且与反馈网络配合产生在反馈网络的固有频率处交替的信号。 限幅器将信号的幅度限制在预定的幅度范围内。 来自振荡器的所有信号被复用到传感器阵列的输出端上。 然后可以使用频率分析来隔离每个振荡器的各个读数。
