Abstract: Electrical Tomography (ET) Images of an object can be generated based on features extracted during an excitation cycle. For example, a method described herein can include selecting, from a plurality of electrodes attached to the object, a first pair of electrodes. The method can include exciting the first pair of electrodes during a first excitation cycle. Additionally, the method can include generating an analog signal by performing measurements across remaining pairs of electrodes of the plurality of electrodes during the excitation cycle. The method can include generating the digital signal based on an analog to digital conversion of the analog signal. Further, the method can include extracting, during the excitation cycle, features based on the digital signal. The method can include generating an ET image associated with the object based on the features.

Abstract: A liquid desalination system is disclosed. The liquid desalination system includes a feed line having an inlet to receive liquid and an outlet to discharge the liquid. The liquid desalination system includes a magnet coupled to the feed line, the magnet to generate an oscillating magnetic field within the feed line and in opposition to the feed water flow. The removal of targeted ions can be achieved by manipulating the frequency and rate of the generated electromagnetic waves. The generated electromagnetic waves can be tuned to weaken the hydration bonds of that specific ion and facilitate its removal. The liquid desalination system generates an electric field across the feed line to enable the liquid to flow through the electric field. The electric field may attract sodium ions to a positive electrode and may attract chloride ions to a negative electrode, to desalinate the liquid in the feed line.

Abstract: Techniques for determining heart rate variability (HRV) and subject data polar images are described. The techniques include determining data of a subject over a period of time that includes time segments and generating HRV feature values from the HRV data. Each one of the time segments is associated with at least one of the HRV feature values. The techniques also include generating, based on the HRV feature values and the time segments, a polar representation of the HRV data and outputting the polar representation as an image. The techniques further include inputting subject data (e.g., demographic data and/or clinical data of a subject) and using them to generate a filled-in color coded image. The generated image can be used further in a deep learning model to predict a heart failure category and decide on time segments or regions within the image that contribute toward the decision.
