摘要： A method for processing a signal on board an aircraft. An electronic control unit receives an input signal including useful data in a first passband, implements a first operation of bandpass filtering the input signal with a first passband to obtain a useful signal containing the useful data, with detection of interference caused by a lightning strike. The electronic control unit implements a second operation of bandpass filtering the input signal to obtain a detection signal, the bandpass filter having a second passband that is distinct from the first passband, comparing a detection value derived from the detection signal with a detection threshold, and correcting the exploitation of the useful data if exceeded.

摘要： An optic probe is used to measure signals from a device under test. The optic probe is positioned at a target probe location within a cell of the device under test, the cell including a target net to be measured and a plurality of non-target nets. A test pattern is applied to the cell with the optic probe a laser probe (LP) waveform is obtained in response. A target net waveform is extracted from the LP waveform by: (i) simulating a combinational logic analysis (CLA) cross-talk waveform to model cross-talk from selected non-target nets by simulating an optical response of the cell to the test pattern with the target net masked; (ii) estimating a cross-talk weight; and (iii) determining a target net waveform by weighting the CLA cross-talk waveform according to the cross-talk weight and subtracting the weighted CLA cross-talk waveform from the LP waveform.

摘要： Systems, methods, and apparatus for detecting UAVs in an RF environment are disclosed. An apparatus is constructed and configured for network communication with at least one camera. The at least one camera captures images of the RF environment and transmits video data to the apparatus. The apparatus receives RF data and generates FFT data based on the RF data, identifies at least one signal based on a first derivative and a second derivative of the FFT data, measures a direction from which the at least one signal is transmitted, analyzes the video data. The apparatus then identifies at least one UAV to which the at least one signal is related based on the analyzed video data, the RF data, and the direction from which the at least one signal is transmitted, and controls the at least one camera based on the analyzed video data.

摘要： A multi-channel capacitive sensor for measuring the capacitances of a plurality of sense electrodes to a system reference potential. The sensor comprises a sample capacitor having a first terminal and a second terminal, a first diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a first sense electrode, and a second diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a second sense electrode. The sample capacitor and diodes are coupled to a control circuit, e.g. implemented in a microcontroller. The control circuit is operable to apply a drive signal, e.g. a series of voltage pulses, to the first terminal of the sample capacitor while simultaneously applying a bias signal to the second terminal of one or other of the diodes to prevent the diode from conducting the drive signal. Thus charge transfer techniques can be used to measure multiple capacitances while sharing a common sample capacitor. This helps reduce inter-channel drift. Further measurement channels may be added by providing further diodes and corresponding sense electrodes. With three or more channels the scheme requires only one additional control circuit connection per additional channel.

摘要： An electromagnetic (EM) sensor includes a front-end module, a memory, and a microcontroller unit. The front-end module generates an electromagnetic signal using externally introduced electromagnetic waves. The memory stores a first reference signal and a second reference signal generated from multiple probability models required to recognize the electromagnetic signal. The microcontroller unit compares the electromagnetic signal with the first reference signal and the second reference signal, to determine whether the electromagnetic signal is a valid signal.
