Abstract: Method and device for impedance analyzer with binary excitation with improved accuracy, where the non-idealities of the sampling and preprocessing of the response signal (including aliasing effects) are taken into account by using of the overall system model with equivalent circuit diagrams of the analyzed object and the model of the preliminary analysis of the response signal. The analysis result is the equivalent circuit diagram with component values with the best match of the overall model analysis and of the preliminary analyze of the response signal. Further, the analysis result can be the impedance frequency characteristic or the classifier of the analyzed object. It could be reasonable to use the pre-calculated function (e.g. in the form of the look-up-table) for matching the results of the over-all model against the preliminary analyzed results of the response signal.

Abstract: Method and device for acquiring stream of the precisely time-stamped images, including the modulated light source, controlled by the absolute global real-time-base (e.g. provided by global navigation satellite system (GNSS) controller) and the image acquisition and processing unit, decoding the light modulation waveform and determining the time-stamp for every image frame. The GNSS time and position messages can be used to provide the full time- and location stamps for each frame. Multi-element light sources can be used to have more informative light modulation in the time domain. For time-stamping of several image streams (e.g. from several cameras) multiple light sources with the same modulation can be used.

Abstract: A method is provided for measuring a frequency response of an object, the method involving: generating an excitation signal having relatively fast changing frequency, defined by a time-domain function; generating at least one reference signal, having a waveform corresponding to the excitation signal; introducing the excitation signal into the object, receiving a response signal from the object; analyzing said response signal in a signal analyzer by correlating the response signal with at least one reference signal during a relatively short sliding time-domain window.
