  • Devices, systems and methods of detecting defects in workpieces
    Patent number: 10132780
    Abstract: Device and method for detecting a defect in a workpiece with a broadband transducer (10), a driving circuit connected to the transducer to operate the transducer in a actuator mode, a signal output circuit connectable to operate in a sensor mode, a control for selectively connecting the transducer to the driving circuit or signal output circuit wherein the driving circuit includes at least a pair of oscillators for generating signals of at least frequencies F1 and F2 and a summer for summing the signals to provide a driving circuit for the transducer.
    Type: Grant

  • Seismic apparatus and method including use of transputers for real time processing of data
    Patent number: 5111399
    Abstract: A seismic processing apparatus comprises a plurality of processing modules (12), each module comprising a transputer (T) and a transversal filter (TF) with these transputers of the modules connected in a linear array by their links. The apparatus is able to carry out real-time demultiplexing of the seismic data from a plurality of receiver channels, and is able to carry out a number of other processing functions in the field, e.g. common depth point stacking, summing, correlation, convolution and two dimensional Fourier transforms.
