  • Unit for storage of building digital technical documentation, on site; any data saved on the unit cannot be either modified, renamed or erased and it is always possible to add new data as required as long as memory capacity is available
    Patent number: 10684967
    Abstract: A unit for managing initial saving, subsequent saving, and reading technical information such as plans, figures, executed works, manuals, notebooks, a visitors' book, maintenance records, and the like of a site such as a building, a ship, a platform, an industrial facility, and the like, the unit comprising a casing incorporating an electronic circuit comprising a non-volatile memory, a USB connector and a processor controlled by firmware controlling the management of inputs and outputs and of the memory, wherein the firmware comprises means for managing the inputs-outputs according to the standard USB protocol, and in addition for preventing the change command from modifying information previously recorded in the non-volatile memory.

  • Device for the simultaneous demodulation of a multifrequency signal, particularly for an eddy current measurement
    Patent number: 5952879
    Abstract: A device for the simultaneous demodulation of a multifrequency signal comprising a processor in which demodulation takes place by calculation. An injector's output signal is multiplied by a complex signal having sinusoids of varying frequencies corresponding to frequency-shifted carriers, thereby transposing the injector's signal on intermediate frequencies.

  • Digital oscillator and supply circuit for an eddy current probe
    Patent number: 5929635
    Abstract: The present invention relates to a digital oscillator comprising an oscillator (40), a counter (41), a memory (42), a digital-analog converter (43) and a low-pass filter (44). The memory is able to directly store a complex signal, rendering the use of a real time calculating unit unnecessary.
