摘要： A received electrocardiogram (ECG) signal is filtered by a set of comb filters, each comb filter filtering a subset of adaptively estimated harmonic components from the received signal. The harmonic signal components may be computed by a sliding fast Fourier transform. Energy values are calculated for the filtered signals. A signal-to-noise and distortion (SINAD) metric is computed based on the calculated energy values. The filtered ECG signal corresponding to a maximized SINAD value is selected, whereby wandering noise associated with the signals is minimized.

摘要： Channel estimation for high mobility OFDM channels is achieved by identifying a set of channel path delays from an OFDM symbol stream including carrier data, inter-channel interference noise and channel noise; determining the average channel impulse response for the identified set of channel path delays in each symbol; storing the average channel impulse responses for the identified channel path delays; generating a path delay curvature for each channel path delay in each symbol based on stored average channel impulse responses for the identified channel path delays; estimating the carrier data in the symbols in the OFDM symbol stream in the presence of inter-channel interference noise and channel noise from the OFDM symbol steam and the average impulse responses for the identified channel path delays; reconstructing the inter-channel interference noise in response to the path delay curvature, the identified set of channel path delays and estimated carrier data; and subtracting the reconstructed inter-channel interference noise from the OFDM symbol stream to produce a symbol stream of carrier data and channel noise with suppressed inter-channel interference noise.

摘要： Corrosion sensors are described. The corrosion sensors may include components formed from carbon nanotube structures and a corroding element formed of a material which corrodes more quickly than a target material being monitored by the corrosion sensor. The corroding material may be exposed to the environment to which the target material being monitored is exposed. The corrosion sensor may be passive, thus consuming little power.

摘要： In a pipeline machine where, in an iterative process, one or more subsequent functions employ one or more parameters determined by one or more antecedent functions and the one or more subsequent functions generate one or more parameters for the one or more antecedent functions, pipeline dependency is reduced by advancing or rotating the iterative process by preliminarily providing to the subsequent function the next one or more parameters on which it is dependent and thereafter: generating by the subsequent function, in response to the one or more parameters on which is it dependent, the next one or more parameters required by the one or more antecedent functions and then, generating by the one or more antecedent functions, in response to the one or more parameters required by the one or more antecedent functions, the next one or more parameters for input to the subsequent function for the next iteration.

摘要： Aspects of the present disclosure are directed to a measurement module for measurement of a multi-electrode resistive sensing element with improved noise performance and accuracy. In some embodiments, stimulation to the sensing element is provided by a current path that originates from a signal source, through a switch block, through a pair of terminals, and ending at a reference node such as ground. An analog-to-digital converter (ADC) is coupled directly to one or both of the terminals to digitize a voltage. The ADC is coupled to terminals on the sensing element to measure a sensed voltage signal before the sensed signal goes through the switch block. As a result, the measured voltage signal may be free of noise that could be picked up from passing through the switch block, and accuracy of the resistance measurements on the sensing element can be improved.

摘要： A reader apparatus with software-controller power exciter, and methods for operating the same to wirelessly interrogate an environmental or structural sensor are disclosed. Some aspects of the application are directed to a reader apparatus that transmits high power for a fast cold start of a sensor and subsequently switch to low power transmission in response to an indication signal received from the sensor indicating that a state of charge of the sensor has reached a threshold value such that high power transmission is no longer necessary, thereby extending battery life of the reader apparatus.
