A system for autonomously validating the topology information of an electrical power distribution system is provided. For example, the system includes a group of meters previously determined to be connected to the same transformer of an electrical power distribution system. The group of meters is configured to perform family check periodically or upon request and to identify orphan meters in the group. The identified orphan meter can contact a community device communicatively connected to meters in more than one group to request a community check. The community device performs the community check by contacting meters in other groups of meters and obtain their family signature data. The community device further determines whether the orphan meter belongs to a new family based on the voltage data of the orphan meter and the family signature data of other groups. The orphan meter can report the community check results to a headend system.

Embodiments described herein relate to a method for modifying transmission line characteristics. The method may include: making a first determination of a null frequency of an input signal to a transmission line; performing an analysis to make a second determination of a wavelength of the input signal using, at least in part, the null frequency; making a third determination, based on the analysis, of a half wavelength of the input signal; calculating, based on the half wavelength, a total stub length; and adding a trace to a stub associated with a via, wherein the stub and the trace are a length that is at least a portion of the half wavelength of the input signal.

Methods, systems, and computer readable media are disclosed for monitoring photovoltaic solar systems. In some examples, the system includes a solar power measurement input for coupling to a solar panel system, a measurement circuit configured to measure power produced by the solar panel system using the solar power measurement input, and a data transmission system. The measurement circuit is configured, by virtue of the measurement circuit including electrical components rated to at least a certain tolerance level, to take revenue-grade power measurements from the solar power measurement input with a level of accuracy that meets a national or international metering standard. The data transmission system is configured to transmit the revenue-grade power measurements from the measurement circuit to a remote system.

Some embodiments described herein include a system that collects and learns reference side-channel normal activity, process it to reveal key features, compares subsequent collected data and processed data for anomalous behavior, and reports such behavior to a management center where this information is displayed and predefine actions can be executed when anomalous behavior is observed. In some instances, a physical side channel (e.g. and indirect measure of program execution such as power consumption or electromagnetic emissions and other physical signals) can be used to assess the execution status in a processor or digital circuit using an external monitor and detect, with extreme accuracy, when an unauthorized execution has managed to disrupt the normal operation of a target system (e.g., a computer system, etc.).

A first power consumption measuring unit 5 measures only the power consumption of a pump 21 that is a reference unit of a liquid chromatograph 2. A second power consumption measuring unit 6 measures only the power consumption of a gas chromatograph main body 31 that is a reference unit of a gas chromatograph 3. An operating information acquiring unit acquires pieces of operating information on an automatic sampler 22, an oven 23, and a detector 24 that are target units of the liquid chromatograph 2 based on information on the power consumption of the pump 21. The operating information acquiring unit acquires the operating information on a head space sampler 32 that is a target unit of the gas chromatograph 3 based on information on the power consumption of the gas chromatograph main body 31. Thus, even in the case where the analyzer includes many target units, only the power consumption of the reference units is measured, and the operating time period calculating unit can acquire the pieces of operating information on the target units from the power consumption of the reference units.
