  • CONTROL OF AN ELECTRIC WATER HEATER AS PER A LOAD SHEDDING REQUEST SIGNAL AND A SALUBRITY INDEX
    Publication number: 20210180829
    Abstract: A system and a method for controlling an electrical water heater as per a load shedding request signal are disclosed. A temperature sensor is positioned so as to measure a water temperature in a lower area of a tank of the water heater to be controlled. A controller continuously determines a salubrity index of the water heater as a function of the temperature measured by the sensor and a time measurement, and decides to interrupt an electrical power supply of the water heater through a switch so as to interrupt or not interrupt an operation of the water heater upon the load shedding request signal and only if the salubrity index meets a preestablished criterion.

  • METHOD FOR THE PURIFICATION OF RAW CARBON NANOTUBES
    Publication number: 20210107791
    Abstract: The present invention proposes a process for purifying raw carbon nanotubes to obtain an content in metallic impurities comprised between 5 ppm and 200 ppm. The process includes an increase in the bulk density of the raw carbon nanotubes via compacting to produce compacted carbon nanotubes. The process further includes sintering the compacted carbon nanotubes by undergoing thermal treatment under gaseous atmosphere in order to remove at least a portion of the metallic impurities contained in the raw carbon nanotubes, and consequently producing purified carbon nanotubes. These purified carbon nanotubes are directly usable as electronic conductors serving as basis additive to an electrode material without requiring any subsequent purification step. The electrode material can then be used to manufacture an electrode destined to a lithium-ion battery.

    Abstract: A computerized method for quantitative analysis of signal related measurements, performed with one or more processors, is disclosed. An estimated signature typifying a characteristic feature of the signal related measurements is produced. Multidimensional statistics on the signal related measurements are computed in a multidimensional space with respect to the estimated signature. Matching likelihoods of the signal related measurements are quantified based on distances of the signal related measurements with respect to a shell manifold derived from the multidimensional statistics and enveloping a signature manifold in the multidimensional space. Multidimensional statistics on the estimated signature and trending and pattern recognition are also possible from the signal multidimensional projection.
