From a mobile device in the subset, a magnetic measurement value obtained by performing a magnetic measurement is received. The magnetic measurement value comprises a change in a magnetic property of an immediate surrounding ambient environment of the mobile device. When the magnetic measurement corresponds to a deviation in a network condition in a portion of a network, the portion being located in the local area, a conclusion is output that the deviation is caused by an electromagnetic disturbance (EMD), where an effect of the EMD causes the magnetic measurement value. A notification including an indication of the EMD and an identification of the local area is generated.

  • Patent number: 9939480
    Abstract: A measurement system includes a current source that is arranged to generate a current pulse to charge a capacitor as a function of an input clock signal. The accumulated charge on the capacitor is converted to a sample (e.g., resultant digital value) by an ADC (analog-to-digital converter). The samples can be aggregated as a distribution in order to estimate the jitter of the input clock signal. Variability of the measurement system can be minimized through calibrating the device-under-test at specific points of PVT (process, voltage, and temperature) conditions. A confidence metric such as a standard of deviation can be derived from the associated samples. The measurement system can be included on a substrate that includes the oscillator that generates the input clock signal.

The reference voltage is used as a reference to match a scale of the voltage of a unit cell selectively connected to the capacitor for each of the first and second polarities with the predetermined voltage range.

  • Patent number: 9939494
    Abstract: A concentration distribution in an active material of a battery unit is calculated by using a diffusion equation, and a first polarization elimination time taken for the concentration distribution in the active material to fall within an allowable range is calculated assuming that charge and discharge of the battery unit is not performed. A concentration distribution in an electrolyte of the battery unit is calculated by using a diffusion equation, and a second polarization elimination time taken for the concentration distribution in the electrolyte to fall within an allowable range is calculated assuming that the charge and the discharge of the battery unit is not performed. It is determined that polarization of the battery unit is eliminated when a time for which the charge and the discharge of the battery unit is not performed is longer than the longer one of the first polarization elimination time and the second polarization elimination time.
