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 for multichannel multifrequency analysis of an object, applying a set of excitation signals to the object and sampling the response signal from the object, using uniform and non-uniform undersampling. Non-uniform sampling of the response signal is performed, i.e., the sampling is performed for two or more different frequencies in one observation time slot. Also, uniform sampling of the response signal is performed, i.e., the sampling of a signal, corresponding to one frequency, is performed for two or more channels within one observation time slot and then sampling the same signal for another frequency for two or more channels within the next observation time slot.

Abstract: Method for determining digital content preferences of the user is combining content access logs with additional information representing user physical activity patterns. For additional information describing changes in user activity pattern recordings from different sensors, like accelerometer, tilt sensor, magnetometer, e-field sensor, etc. integrated into handheld device will be used. Certain typical sensor patterns present higher or lower user interest comparing to an average.

Abstract: A method and device for high speed broadband testing of systems and substances using a binary, spectrally sparse sequence (SSS) as a periodic excitation waveform. The sequences with controllable frequency and magnitude spectra content are designed by component manipulation method or by edge manipulation method. The excitation waveform is typically pre-calculated, and kept in waveform memory, from where it is shifted out into digital to physical quantity converter (DQC). The sparse spectrum of the SSS makes it easy to create plenty of uncorrelated frequency sets with adjacent, but sufficiently different frequencies to form multi-path test systems, where all the paths can be measured simultaneously. The response of the sample under test (SUT) is sampled and the complex transfer function is calculated directly or indirectly via Impulse Response by Discrete Fourier Transform technique and its derivatives. The sequence bit interval and sampling interval have a predetermined ratio.

Abstract: A method for impedance measurements, using synchronous detecting and modified rectangular signals. The method comprises introducing a first modified rectangular signal into a bioobject, receiving a response signal from said bioobject, introducing said response signal and a second modified rectangular signal into a synchronous detector, whereas either one or both rectangular signals are modified to remove particular higher harmonics from the signal. In one embodiment, either one or both the first and the second modified rectangular signals are generated by summing at least two modified rectangular signals, wherein at least one of such rectangular signals have a zero amplitude segment introduced between rectangular half periods.
